A drawing of making a vibrating table with your own hands. Do-it-yourself vibro-tables for paving slabs

The manufacture of paving slabs, as well as products from concrete, gypsum or building mixtures, provides for compaction of the working composition. Under the influence of vibration, the working solution fills the corner sections of the form, acquires increased strength and the necessary structure. In order to manufacture concrete products intended for domestic use, you can make a vibrating table with your own hands. This inexpensive and easy-to-manufacture equipment is not inferior to industrial designs in terms of work efficiency.

Getting to know the equipment - vibration table

For machine molding of concrete products, poured into special molds, vibration equipment is used - universal vibrating table. It is possible to make the unit with your own hands, most importantly, to understand its purpose, device and principle of operation. The equipment is a metal structure with a pivotally fixed working platform on which the molds are placed.

The stove makes up to three thousand vibrations in one minute, which allows:

increase the density of the concrete mass;
increase strength characteristics;
get rid of air inclusions.

As a result of vibration exposure, the concrete structure is compacted, which positively affects the quality, as well as the service life of paving slabs and other types of products.

What is the vibrating table intended for?

Small-sized vibrating platform, made in domestic conditions, is designed to solve a wide range of problems:

The performance of the device is determined by the area of \u200b\u200bthe working plate, as well as the intensity of the vibrations.

Vibrostable - design features

The platform intended for vibration molding is a mechanism consisting of the following elements:

steel frame. It is a massive metal structure of vertical posts, to which the jumpers are rigidly welded;
working plate. It is a horizontal base with a shoulder on the upper contour, limiting the mobility of the forms;
vibration motor. When installing the engine for a vibrating table with your own hands, you need to pay attention to the mass of the eccentric, transmitting the oscillation plate;
movable mount. It provides the connection of the plate with the bed. Represents four spring elements installed in glasses;
starting machine. It performs the functions of supplying and disconnecting voltage to the vibration motor, and also protects against thermal overloads.

When deciding how to make the vibrating table itself, you should pay attention to its performance characteristics.

What is the device of the vibrating table?

The main parameters affecting the effectiveness of compaction and the quality of manufactured products:

amplitude of oscillatory motion;
frequency of rotation of the vibromotor shaft.

For optimum performance it is necessary:

choose the right eccentric design;
choose a mounting location for the vibration drive;
equip the site with an electric motor of rated power.

The selection of optimal modes is carried out experimentally.

How does a homemade vibrating table

Before making a vibrating table, it is necessary to study the principle of operation of the unit.

The molding device works quite simply:

Homemade vibrating table from the washing machine and industrial equipment operate according to the same algorithm.

Getting ready to make a vibrating table with your own hands - materials and tools

Prepare everything you need to make a vibrating table with your own hands. Drawings allow you to determine the list of materials for its construction.

Need to prepare:

Installation of a frequency regulator will allow changing the molding intensity in the manufacture of products from various building materials.

We make a homemade vibrating table with our own hands - simple solutions

When planning to make a universal molding vibrating table with your own hands, drawings must be purchased in advance or drawn on your own. It is important to determine the design features of the vibrating unit. The following types of vibration compactor are used:

molding equipment. It is used for vibration ramming of concrete mortar poured into lithforms;
decoupling device. Designed to remove hardened products from molds using a special device;
non-standard design options. Used to make a limited number of products at home.

The advantage of a simplified design is the ability to assemble for a limited time without additional cash costs using existing equipment and materials.

DIY simple vibrating table

The simplest options:

based on car ramps. To assemble the tamping device, you need 2-3 slopes, a hammer, and also a wooden shield, the dimensions of which allow you to place the forms. The compaction process occurs when the molds are mounted on a wooden board located on the tires. When tapped with a rubber hammer, the concrete composition is compacted;
using a drill or punch. The design uses a plate made of a metal sheet or a wooden board. The table top is placed on a horizontal basis and abuts against the wall with a damper made of a piece of rubber. When you turn on the punch, brought to the opposite side of the base, the material is compacted.

Other options are also possible, involving the use of an old washing machine, as well as used electric motors from household appliances.

We develop a drawing of a vibrating table

You need to know, developing a drawing on a vibrating table, how to do it correctly.

For this it is necessary:

use proven documentation, which previously produced a vibration platform;
independently develop a sketch using a valid sample.

the optimal dimensions of the countertops are 50x100 cm;
the distance from the floor to the working surface should not exceed 80 cm.

How to make a vibrating table yourself

When developing a drawing, it is important to consider the following requirements:

the engine should not touch the base or structural elements;
the surface of the desktop is horizontal;
the legs of the frame should be of equal length to ensure stability;
stiffeners are installed in the corners to increase stability.

Prior to the development of working documentation, you must first determine the dimensions of the unit and the mounting location of the motor. It is advisable to place the vibration motor in the center of mass of the entire metal structure.

We select the engine for the vibrating table

Various motors can be used as a source of oscillation.:

second-hand or new motor up to 1000 watts. It is able to transmit vibration to the countertop with dimensions of 0.8x1.5 m. Two eccentrics must be fixed on the drive shaft of the electric motor, the angular position of which can be changed. This will allow you to adjust the amplitude and strength of the oscillations;
industrial vibration vibrator. It should be attached to the surface of the desktop. The standard vibrator motor is equipped with eccentrics mounted on opposite sides of the shaft. By adjusting the mutual position of the imbalances, you can change the level of vibration exposure.

In a home-made version of the vibrodrive, the motor shaft bearings are subjected to increased loads under the influence of alternating vibrations. The specified disadvantage is deprived of a purchased vibrator having an increased service life.

Engine for a makeshift vibrating table

It is also possible to fix the shaft to the bearing supports to the lower plane of the table, which has an offset center of gravity. Using a belt drive, the structure can be connected to the motor pulley. The level and direction of vibration in this embodiment is regulated by the position of the eccentrically fixed load.

How to make a vibrating table with your own hands - drawings and instructions

According to previously developed drawings, it is easy to make a vibration platform, guided by the following algorithm:

It is important to weld frame parts that absorb vibration loads.

How to make a vibrating table with your own hands without errors

When performing work, pay attention to the following points:

the presence of a side around the perimeter of the table;
the ability to adjust the amplitude of the oscillations;
reliability of fixing the frame to the floor;
weld quality;
horizontal when installing countertops.

The manufacture of the site according to the drawings will avoid errors.

DIY vibration table manufacturing - safety requirements

Observe safety measures during assembly and device:

use safety glasses when welding and working with the “grinder”;
ground the power tool and the device drive;
carry out welding work in special clothes.

Do not forget that in the room where they cook, there must be a fire extinguisher.

Conclusion

Recommendations will help to independently produce a vibration platform. Manufacturing technology is simple. It is important to carefully consider the design features, take the design of the sketch seriously and follow the sequence of operations. A self-made unit will provide effective sealing of products at home.

The production of paving slabs is carried out using the method of vibrocasting. For this, a special device is used - a vibrating table. At home, there is nothing to replace it, so you have to make it yourself.

How to make a vibrating table for the manufacture of paving slabs? Let's consider this question in more detail.

The process of concrete hardening, accompanied by small frequent fluctuations, proceeds with the release of air bubbles, compaction of the concrete structure and an increase in the density and strength of the material. To ensure this mode, a vibrating table is used.. It is a surface that makes frequent oscillatory movements (of the order of 3000 / min).

Concrete molds are mounted on this surface and vibration processing is performed. Mode significantly compacts the structure of concrete, which significantly affects the quality of paving slabs, the operating conditions of which require great strength.

There are different types of devicesFrom large industrial ones with a hydraulic source of vibrations for processing large concrete blocks, to smaller electrical ones that vibrate with an eccentric mounted on the motor shaft. Since only the second option is available at home, we will not consider the hydraulic drive device.

Vibration frequency and amplitude - characteristics that determine the texture of the processed material. They are set up empirically, it is too difficult to calculate all the nuances in advance, because too many variables are involved in the process.

Therefore, the design of the table should provide for the possibility of some adjustment of the amplitude of the oscillations.

Find out how to stack on our website. We will tell about the successive stages of the work performed.

And you will find a lot of useful information about preparing the site for laying paving slabs.

Materials and tools that will be required

The specifics of the device allows the use of only metal elements. All joints are welded or bolted. Accordingly, for the manufacture need sheet metal with a thickness of 3 mm (the larger the area, the thicker the sheet will be needed).

For the bed you need a corner or channel. Table springs provide mobility, the size of which must correspond to the weight of the table plus the load of the installed molds.

To assemble a vibrating table for paving tiles with your own hands need a welding machine, electric drill with a set of drill bits for metal. Cutting metal parts is a grinder. You will need a measuring tool, a set of wrenches for threaded connections.

The legs of the table require reliable fixing to the floorotherwise, during work, he will run around the room. It is best to cement the legs into the recesses, for which it is necessary to weld the plates of sheet metal to the ends and deepen by 10-15 cm.

If possible, pour anchors into the floor and attach the table to them, this option will, if necessary, disconnect the device and move it to another location.

How to draw a drawing

Manufacturing work you need to start by creating a device drawing. Making at random is not recommended, since it is difficult to remodel a knot connected by welding.

All dimensions must be calculated in advance., distance, engine mounting location, so that its location is as close as possible to the center of mass of the table. If the eccentric is not located on the motor shaft, but on a separate drive, then it is placed in the center. Creating a drawing must begin with a bed.

Take into account the height, type of attachment to the floor, the perimeter of the strapping of the bed in terms of repeats the contours of the working surface. This is necessary, since the springs are located at the corners and at the central points of the sides of the table.

How to choose the right engine

The table area is selected based on engine power, which should not be too large. Usually enough power up to 1 kW. A table with dimensions of 1500 by 800 mm is suitable for such an engine.

Dimensions are approximate, since the table mass and engine shaft speed are not taken into account. In general, care must be taken not so much about power as about the condition of bearings or bushings.

They bear the entire load, and to ensure long-term operation, you need to choose a motor with reliable bearings. If necessary, if design permits, you can modify the engineby removing the bushings and replacing them with reinforced bearings.

If you plan to install an eccentric directly on the motor shaft, this procedure will significantly extend the performance of the motor.

Manufacturing instruction

On this, the assembly process of a home-made vibrating table for paving slabs can be considered completed, it remains to start the device and adjust the amplitude of the vibrations by changing the position of the eccentric.

Important nuances, error prevention

On the perimeter of the working surface of the table, a side is needed to prevent the mold from slipping with concrete.
If long bolts are used as guide rods for springs, the springs can be slightly tensioned by screwing nuts with washers to more securely fix the table and limit the amplitude of vibration.
Instead of a conventional electric motor, you can use a type IV99 vibrator or the like, with which you can more accurately control vibrations and get a quality result.

Security measures

All work should be carried out in a room intended for such actions. Welding work, as fire hazardous, must be carried out with the availability of fire extinguishing means.

Cutting, drilling and other metal work are performed in compliance with safety precautions. Attention should be paid to working with the grinder.

The first start is best done with the drive belt removed.to eliminate the consequences of improper connection or attachment of nodes.

Protective grounding must not be forgotten.which must be connected before the test run.

In this video, see how you can make a vibrating table for the production of paving tiles with your own hands:

The assembly process of the vibrating table does not take a lot of time, usually its installation is completed in one day.

Setting the mode can be performed almost instantly, or drag out for some time, since the most optimal option is found experimentally.

An aggregate made in this way can serve for a long time, and can be used both for the production of paving slabs, and for other works with concrete, ceramics, or other compositions requiring vibration processing.

Making paving slabs with your own hands is quite an interesting process, but for this you need certain materials and tools. One of these is the vibration table, which we promised to write about.

In the previous article we talked so be sure to read. And today you will learn how to make a vibrating table yourself.

Device requirement

Concrete hardening is always accompanied by slight fluctuations in which air bubbles are released. Due to this, the future product becomes durable, and the structure of concrete is compacted. In order to ensure this and need a vibrating table. It oscillates at a frequency of 3000 movements per minute.

All vibrating tables can be divided into two types:

Industrial with hydraulics;
Home use, creating vibrations using an eccentric mounted on an electric motor.

It is the latter that we will consider.

Important! Since it is impossible to deliberately calculate the number of vibrations, the vibrating table must have an amplitude adjustment function.

But first things first.

In order to make a vibrating table with your own hands you will need:

Metal sheet with a thickness of at least 3 mm;
Springs;
Channel and corner;
Pipes
Electric drill;
Welding machine;
Bulgarian;
Spanners;
Metal legs;

Drawing

First of all, you need to draw a drawing of the future vibration table or download it ready on the Internet. It is important that all dimensions, the required distance, are calculated in advance.

The engine should be placed closer to the center. The drawing itself is drawn starting from the bed. When creating a drawing, do not forget to take into account the height of the table and the methods of attachment to the floor.

Engine selection

When making a vibrating table for a tile, you need to pay attention not only to the structure itself, but also to the engine, because the whole load will come to it. More specifically, on bearings and the sleeve. Therefore, when choosing an engine, do not rely on its power, because 1-2 kW is enough for home use. But the bearings should be of high quality and reliable. As a last resort, during operation you can replace them.

One more tip! By installing the cam directly on the shaft, you significantly extend the life of the motor.

Production of vibrating table for paving slabs

We proceed to assembly only after preparing the drawing.
Based on his data, we cut the blank for the future bed. Corner - 45 mm. Pipes must be at least 65 mm in diameter. Length, depending on the desired table height. We weld all the necessary elements and only then weld the metal sheet.
After that, you need to take the spring and cut it into pieces of the same length, in the amount of ten pieces.
Then, we weld springs to the finished frame: at the corners, in the center and between the corner and the center at the same distance.
From the remaining pieces of the pipe, we make glasses and weld them on the underside of the table. In diameter, they should be 3 mm larger than the springs and positioned exactly to their placement.
For reliable fixation, rods can be welded.
After welding, you need to set the table on the bed.
The eccentric mechanism is welded from below, in the center.
The engine is mounted at a distance that corresponds to the length of the belt.
At the end, you need to install the on / off button, connect the power.

On this assembly and installation is completed. You can start and calibrate the amplitude of the oscillations, if necessary. This is done by moving the eccentric.

Mistakes and how to avoid them

Be sure to make a side around the perimeter of the surface of the table, so that when the form with the tile does not fall.
To limit the amplitude, it is possible to weld the bolts instead of the springs for the springs, onto which the washer and nut must be screwed.
In order to more accurately regulate vibrations, install not an engine, but an IV-99 type vibrator.
Securely fix the legs so that the table “does not go” in the process. It is best to cement them.
The legs of the vibrating table should be high enough so that you do not have to bend.
The motor must not touch the ground.

Security

When making a vibrating table for paving tiles with your own hands, do not forget about safety! First of all, wear protective equipment when carrying out welding work.

Work with the grinder carefully so as not to damage your hands.
Remember to ground before turning on the vibrating table.
When starting the technical device for the first time, remove the drive belt to eliminate the negative consequences associated with incorrect connection.

As you can see, it is not so difficult to make a vibration table to create a tile, it is enough to adhere to certain rules. If they are followed, the product will serve you for more than one year, and as a result you will get high-quality tile.

Of course, it will differ from the factory in any case, but it will come out much cheaper. Save up to 20%, even when assembling a vibrating table.

And so that you see a clear example of the assembly, watch the video below.

The issue of designing tracks on a site sooner or later faces all owners of the sites. The option of using paving slabs for this purpose is one of the most simple, reliable and beautiful. Therefore, for self-manufacturing and laying, you will need instructions on how to make a vibrating table for paving tiles with your own hands. This article will discuss all the nuances of the assembly of the device, as well as the recommendations of specialists in the manufacture of the frame and the choice of engine.

A vibrating table, or as it is also called, a vibrating press is a special device designed for the manufacture of paving slabs. The main advantage of this device is the ability of its working surface to oscillate. In addition, the vibrating table can be used for other purposes, for example, for the manufacture of monuments, sections of concrete fences, etc.

As for the independent manufacture of the vibrating table, this is most often resorted to when they want to independently engage in the manufacture of paving slabs to decorate their own yard. Although in some cases, this method is used to organize your own small business.

Of course, using a vibrating table, it is definitely impossible to engage in production on an industrial scale, but given that it can be made from improvised materials, and with its main functions - eliminating air bubbles and compacting the composition of the forms, such a device will cope perfectly.

As much as possible we will consider what is needed in order to make a home-made vibrating table, as well as step-by-step instructions for its manufacture.

Types of equipment for the production of paving slabs

Vibrating tables are different, and before proceeding to manufacture, it is necessary to determine the appropriate option and its features. So, depending on the direction of vibration, these types of devices are distinguished:

Models with horizontal vibration.
Models with vertical vibration.

These types of devices are divided depending on how exactly the rotor is located in them. In this case, the first option (table with horizontal vibration) is more popular.

Depending on the installation method, vibration tables can also be divided into two types: stationary and portable (mobile). But depending on the specialization of the devices, those that are designed to form products, as well as those that are designed to extract the finished product from the mold using vibration, are distinguished.

Externally, the molding and forming tables are practically no different, except for a special nozzle with holes, on which the mold is installed, from which it is necessary to remove the finished product.

If you want to make your own machine for the production of paving slabs, it will be quite enough to make a vibrating table with horizontal vibration. In this case, you can remove the tile in two ways: manually (usually flexible forms are used in the home workshop) or by installing a molding nozzle.

The technology of paving slabs: the principle of the machine

In order to understand how to properly make this or that device, you need to understand the manufacturing technology of those elements for which it is designed. Therefore, we consider the principle of operation of the vibrating table and what each of its components is intended for.

The working surface of the table is attached to the bed using a special spring system, if it is a horizontal vibration device or with the help of suspensions, in the case of vertical devices. Due to the operation of an electric motor of rated power, on the shaft of which an eccentric, the tabletop is set in motion. Due to the fact that the eccentric shifts, the center of gravity changes, resulting in the desired vibration.

How to make a vibrating table with your own hands: drawings and description

A general idea of \u200b\u200bthe device of the vibrating table can be obtained by reading the sketch. But for the independent manufacture of such a design, a full-fledged drawing is required, which will allow you to take into account all the nuances and pre-designate the necessary dimensions of each of the elements.

Before you start creating a drawing, you should consider the two most popular options: for beginners and for masters. In the first case, the vibrating press has a simpler design, but it allows you to perform the main task - to form products. The assembly, maintenance and care of such a device is quite simple and quite possible even for a novice master.

Helpful advice! Over time, additional features such as a sand screener can be added to such a simple design. The main thing is to correctly carry out all the necessary calculations so that the addition of new functions does not cause the failure of the basic elements.

More complex designs designed for craftsmen initially combine a vibrating press and a sand screener. In the assembly, such a design is more complicated, however, it is convenient in that it facilitates the process of obtaining the components of the desired fraction.

Step-by-step instructions for manufacturing a horizontal vibrating table

The first thing you should pay attention to before starting work is the size of the countertop. It is believed that the minimum surface size should be 600x600, since with narrower sides, the shapes will fall during movement. In addition, the narrow design will have less stability.

Helpful advice! If in the process of making paving slabs at home the forms nevertheless fall off, you can try to reduce their number. This will negatively affect the performance of the device, but in this case the number of tiles damaged due to falling will be reduced.

In many ways, the size of the vibrating table is determined by the required volume of production. We can say that there is a direct correlation - the more elements must be made at a time, the larger the area of \u200b\u200bthe countertop should be. Naturally, for a large vibrating press, a more powerful engine will be required, and the materials from which the structure will be assembled must be very durable.

As for the height of the vibrating table, it all depends on the individual data of the person who has to work for him. A standard height, optimally suitable for a person of average height, is considered to be 90-100 cm.

Important! When determining the height of the table, it is worth taking into account the installation method that will be used. So, for example, if a stationary device needs to be dug into the ground and cemented, then the length of the legs of the table must be taken into account in advance.

Materials and tools necessary for the assembly of a vibrating table: prices and specifications

In order to assemble the structure yourself, you will need a grinder, a welding machine, a drill, as well as the ability to handle them. Consider the list of necessary materials that can be found among the handouts.

For the countertop, you can use plywood or a sheet of metal of a suitable size. In this case, the plywood sheet should be 14 mm thick. This will allow to transfer a greater amount of vibration due to the small thickness, but at the same time provide the necessary structural strength. In addition, this way you can significantly reduce the noise level during operation of the device. If a metal sheet is used, then its thickness should be in the range of 5-10 mm.

The cost of a plywood sheet of the desired thickness made of birch veneer will be about 650 rubles with a standard size of 1525 × 1525 mm. But a sheet of hot-rolled metal with a thickness of 5 mm will cost more, about 1000 rubles.

Helpful advice! If a metal sheet of smaller thickness is available, it can also be used by reinforcing the structure with metal corners or pipes welded to the center of the sheet and around the perimeter.

Metal corners measuring 50 × 50 mm. They will be required to create a fringing of the countertop and during operation of the vibrating table will not allow the forms for the production of paving slabs to move from the surface as a result of vibration. Their cost will be about 140 rubles per 1 m.

Channel for mounting the motor (about 210 rubles / mp). It will need to be welded in the center of the reverse side of the countertop, having pre-drilled holes that will be used for the bolts holding the motor.

Metal pipes for table legs. Typically, elements with a thickness of 2 mm and a size of 40 × 40 are used for this purpose. The price will be 107 rubles per 1 m.

Pipes for forming the upper and lower parts of the frame. Since the main load will be precisely on these elements, it is worth choosing a rather strong material - 40 × 20 and 2 mm thick for the upper part and at least 20 × 20 of the same thickness for the bottom. The cost will be 84 rubles / m. and 53 rubles / mp respectively.

Metal plates to be used as the sole for the support legs. For this, pieces of metal with a size of at least 50 × 50 and a thickness of 2 mm are suitable.

You will also need a plate for installing electrical equipment and springs, which are designed to provide vibration. It is quite possible to purchase these elements at the autodismantling. Numerous reviews indicate that the ideal option is to use springs from mopeds, the cost of which at a height of 113 mm and a diameter of 54 mm will be about 500 rubles. They are installed in the corners of the table, and with a large surface area, another one is additionally mounted in the center.

Important! If an additional spring was installed in the center of the countertop, then the engine mounting location and the support configuration will be changed.

Additional aspects that you should pay attention to when choosing materials for a vibrating table

In addition to the above materials, it is worthwhile to carefully select other components that, although not visible, largely determine the quality of the device:

bolts for fixing the springs. This element acts as a cup for the spring, so it must have the proper strength. Sometimes, pipe blanks of a length of 50-70 mm are used for this purpose. It is important that their diameter exceeds the spring diameter by 5-10 mm;
bolts and washers (usually 4 pcs.), which are required to fix the engine;
electrical cable, which must have a sufficient cross-section. It is also worth considering the presence in the immediate vicinity of an outlet and a circuit breaker.

Important! If the diameter of the home-made cup will significantly exceed the diameter of the spring itself, this will lead to the fact that the vibration will be uneven. As a result, the spring will quickly wear out, and the movement of the table could be called swinging rather than vibration.

Production of paving slabs at home: how to choose an electric motor

Consider the two most popular options: their cost and characteristics:

IV-99 E with a power of 0.5 kW. Its weight is 14.5 kg, rotation speed 3000 rpm, driving force up to 5 kN. The device receives power from a network with a capacity of 220 V. You can purchase it at a price of 7650 rubles.
IV-98 E is a more powerful model (0.9 kW), which has a larger weight of 22.5 kg and a driving force of up to 11 kN. Moreover, the rotation speed is also 3000 rpm. But the main difference between this model and the previous one is the presence of unbalances on the rotor, which rotate together with the rotor shaft. For power, a regular 220 V network can also be used. The cost of this model is 8540 rubles.

For the production of a small amount of tile this will be more than enough, but if you want to organize a small paving slab factory in your workshop, then it is better to pay attention to the model IV-104 B, with a capacity of 0.53 kW. For its power supply, a 380 V network will be required, however, this will make it possible to achieve a driving force of 6.3 kN.

But there are cases when it comes to the manufacture of a very small amount of paving slabs for paths to the cottage, and acquiring a motor for this purpose is simply unjustified. In this case, craftsmen use the engine from an old washing machine or pump station as a basis. In this case, you will have to spend much less money, paying only a turner for some alterations, if necessary.

The only significant drawback of this solution is the fragility of old engines. They are extremely rarely able to withstand more than three dozen work cycles. After this, the axis breaks up or the bearing completely seizes. Therefore, if it is planned to manufacture a large number of tiles, it is better to purchase a more durable engine that can last the required period of time.

Important! The main task of the engine is to ensure uniform surface vibration, since otherwise, the solution may boil in the tank, which will lead not to compaction, but, on the contrary, to increased fragility of the products.

Even taking into account the need to purchase all the necessary elements, making such a design with your own hands is much cheaper than buying a vibrating table for paving slabs.

Do-it-yourself vibro-table for paving slabs: construction assembly rules

After all the necessary materials have been purchased, it remains only to assemble the structure together. But in order for the resulting device to function properly for many years, you must adhere to the following rules:

All metal elements must be opened with an anti-corrosion compound before assembly. This will provide them with reliable protection against rust. GF-021 Lacra primer, the cost of which is only 125 rubles / kg or paint-enamel, is perfect for this purpose. At the same time, if you have to deal with elements that have already undergone corrosion processes, you will have to purchase more expensive material, for example, the primer EP-0180, worth 188 rubles / kg.
To fasten the components of the vibrating table, it is necessary to use a weld. Bolts for this purpose are not used because over time, as a result of exposure to vibration, they can become loose, which will lead to a decrease in the rigidity of the support. This solution is allowed only for collapsible structures, but in this case, it is necessary to regularly tighten the bolts.
It is very important that the motor, which produces the vibration, in no case comes into contact with the ground. This is not allowed by the technology for the production of paving slabs, and therefore, before proceeding with the manufacture of the first batch, the device must be tested by running and checking the amplitude of oscillations and the stiffness of the springs.
All legs of the support should have the same length. However, in order to make it convenient to use the table, you must also take care that the surface on which it will be installed is flat. This will avoid distortions and make the process of manufacturing paving slabs for summer cottages as efficient as possible. It is wise to consider fixing the table to the surface. This can be done using suitable anchors or concrete mortar.

Helpful advice! In some cases, the ideal engine location can only be determined empirically. If something does not suit you in the vibropress, you can experiment a bit to achieve the desired effect and ease of use.

Vibration table motor imbalance methods

Depending on where the engine is installed, it is necessary to unbalance the belt drive unit on the countertop or on the pulley. There are several ways to do this:

to put a round pulley on the shaft, from which a section of the circle is drilled or grinded;
experimentally select a nut that is suitable in size and weight, and weld it to the pulley;
put the coupling on the shaft, having previously welded a bolt with two nuts placed across its end. Due to the fact that the nuts can be moved along the thread, imbalance is carried out.

As you can see, the independent manufacture of paving slabs for summer cottages is a feasible task if you spend time and effort studying the issue and assembling the necessary device. Although it should be noted that with the help of such a vibrating table it is possible to organize, for example, a small production of polymer sand paving slabs.

Vibrating table is used for the production of polymer-sand paving slabs, concrete fence elements, figures, monuments, statues, by the method of vibrocasting

Using vibrating table and special shapes, it is possible to make paving slabs of any size and configuration

Types of equipment for the production of paving slabs

Models with horizontal vibration.
Models with vertical vibration.

These types of devices are divided depending on how exactly the rotor is located in them. In this case, the first option (table with horizontal vibration) is more popular.

The working surface of the table is attached to the bed using a special spring system, if it is a horizontal vibration device or with the help of suspensions, in the case of vertical devices. Due to the operation of an electric motor of rated power, on the shaft of which an eccentric, the countertop is set in motion. Due to the fact that the eccentric shifts, the center of gravity changes, resulting in the desired vibration. For the convenience of working with a vibrating table, the height of the legs of the base should be taken into account

Helpful advice! Over time, additional features such as a sand screener can be added to such a simple design. The main thing is to correctly carry out all the necessary calculations so that the addition of new functions does not cause the failure of the basic elements.

Helpful advice! If in the process of making paving slabs at home the forms nevertheless fall off, you can try to reduce their number. This will negatively affect the performance of the device, but in this case the number of tiles damaged due to falling will be reduced.

Important! When determining the height of the table, it is worth taking into account the installation method that will be used. So, for example, if a stationary device needs to be dug into the ground and cemented, then the length of the legs of the table must be taken into account in advance.

Materials and tools necessary for the assembly of a vibrating table: prices and specifications

An example implementation of a vibrating table for the manufacture of paving slabs with a forming nozzle

The cost of a plywood sheet of the desired thickness made of birch veneer will be about 650 rubles with a standard size of 1525 × 1525 mm. But a sheet of hot rolled metal with a thickness of 5 mm will cost more.

Helpful advice! If a metal sheet of smaller thickness is available, it can also be used by reinforcing the structure with metal corners or pipes welded to the center of the sheet and around the perimeter.

Imbalances are used to excite oscillations in the vibration mechanism of the vibrating table.

Channel for mounting the motor It will need to be welded in the center of the reverse side of the countertop, pre-drilled holes that will be used for the bolts holding the motor.

Metal pipes for table legs. Typically, elements with a thickness of 2 mm and a size of 40 × 40 are used for this purpose.

Reliability of fastenings of all elements of the vibrating table ensures the correct operation of the device, the quality of the manufactured products and the duration of the operation

Metal plates to be used as the sole for the support legs. For this, pieces of metal with a size of at least 50 × 50 and a thickness of 2 mm are suitable.

Important! If an additional spring was installed in the center of the countertop, then the engine mounting location and the support configuration will be changed.

Additional aspects that you should pay attention to when choosing materials for a vibrating table

In addition to the above materials, it is worthwhile to carefully select other components that, although not visible, largely determine the quality of the device:

bolts for fixing the springs. This element acts as a cup for the spring, so it must have the proper strength. Sometimes, pipe blanks of a length of 50-70 mm are used for this purpose. It is important that their diameter exceeds the spring diameter by 5-10 mm;
bolts and washers (usually 4 pcs.), which are required to fix the engine;
electrical cable, which must have a sufficient cross-section. It is also worth considering the presence in the immediate vicinity of an outlet and a circuit breaker.
Important! If the diameter of the home-made cup will significantly exceed the diameter of the spring itself, this will lead to the fact that the vibration will be uneven. As a result, the spring will quickly wear out, and the movement of the table could be called swinging rather than vibration.

Production of paving slabs at home: how to choose an electric motor

Consider the two most popular options: their cost and characteristics:

IV-99 E with a power of 0.5 kW. Its weight is 14.5 kg, rotation speed 3000 rpm, driving force up to 5 kN. The device receives power from a network with a capacity of 220 V. You can purchase it at a price of 7650 rubles.
IV-98 E is a more powerful model (0.9 kW), which has a larger weight of 22.5 kg and a driving force of up to 11 kN. Moreover, the rotation speed is also 3000 rpm. But the main difference between this model and the previous one is the presence of unbalances on the rotor, which rotate together with the rotor shaft. For power, a regular 220 V network can also be used. The cost of this model is 8540 rubles.

Important! The main task of the engine is to ensure uniform surface vibration, because otherwise, the solution may boil in the tank, which will lead not to compaction, but, on the contrary, to increased fragility of the products.

Even taking into account the need to purchase all the necessary elements, making such a construction with your own hands is much cheaper than buying a vibrating table for paving slabs. The power of the electric motor determines the duration of the machine and the required amount of produced paving slabs

Vibration table motor imbalance methods

Depending on where the engine is installed, it is necessary to unbalance the belt drive unit on the countertop or on the pulley. There are several ways to do this:

to put a round pulley on the shaft, from which a section of the circle is drilled or grinded;
experimentally select a nut that is suitable in size and weight, and weld it to the pulley;
put the coupling on the shaft, having previously welded a bolt with two nuts placed across its end. Due to the fact that the nuts can be moved along the thread, imbalance is carried out.

For reliable long-term operation of the vibrating table, it is worth using steel elements and a cooking apparatus for fastenings
