It will not be a revelation to anyone that cinder block is one of the most popular building materials. From such blocks you can build both residential buildings and utility buildings (garages, warehouses, etc.). This product has many advantages, the most important of which is the ability to make it yourself.
For these purposes, homemade machines are used for the production of cinder blocks. It must be said that there is nothing complicated in the construction of such a device; any novice master can make it.
Machines for the production of cinder blocks make it possible to produce high-quality building material not only for the purpose of saving Money, but also for the opportunity to produce them for sale. This activity could turn into profitable business, But that is another topic.
In this article we will talk about this homemade equipment, which will allow us to produce hollow concrete blocks for construction.
Let's say right away what this is for technological process we will need:
- Special foam fillers;
- Granular slag;
- Cement.
The resulting products will have good thermal and sound insulation properties.
Making a mold for blocks
On the World Wide Web, for example, on specialized forums, you can find drawings of a machine for the production of cinder blocks for free. But if you don’t want to waste your time, then you can use the drawings given in this article, with the help of which you can easily make the necessary equipment for the production of cinder blocks with your own hands.
Almost all such mechanisms make it possible to produce both solid and hollow blocks. The most primitive design is a collapsible form without vibration, which you can see a little lower.
Note that in most cases, for the production of such blocks with voids, they use concrete mixture with increased liquid content.
Sequence of block production
- We fill the molding box (matrix) with concrete;
- We keep the solution in the matrix until it sets (about 2-3 hours);
- Disassembling the matrix - the building material dries in a free state.
Advice. Useful for the production of hollow blocks glass bottles, cans and other cylindrical objects.
They fit well in size and can be found in any household.
In addition, you can make special cylinders from tin, they will be more durable.
To create the bottom and walls for such matrices, sheets of plywood or metal are suitable. Remember that before pouring the concrete mixture into the matrix, it must be lubricated with machine oil. Even working off is suitable for these purposes.
Homemade vibrating machines
Such cinder block production machines are more advanced equipment. It is more convenient and faster to make blocks using them, because they do not require waiting for the solution to set. For such machines concrete mortar It cooks thicker and tougher, and also has a slight shrinkage.
Technically, this can be implemented in two ways:
- using a vibrating table;
- equip the mold itself with a motor, on the shaft of which an eccentric with a shifted center of gravity is installed.
Such devices with eccentrics are more convenient for the production of large volumes of material, because they allow you to obtain ready-made blocks without turning over.
Important. If you do not have enough time to create such mechanisms yourself, then you can use your regional newspaper with advertisements.
Typically, people who have completed the construction of their homes sell used cinder block machines.
Homemade laying hen machine
This machine is the simplest, and its design includes the following elements:
- molding matrix without bottom;
- vibration mechanism on the side wall;
- handles on the drawer, which are designed to quick removal block;
- sets of pressure plates that are replaceable;
- void formers for various forms voids.
The production instructions state that the standard block is 39 x 19 x 18.8 cm. With such dimensions, the voids should be no more than 30%.
Blacksmithing is hard physical work that requires special equipment combined with specialized knowledge and experience of the master. However, to make some artistic elements, you simply need to bend the blanks at the desired angle. Metal deformation can be performed without heating mechanically, for this purpose machines are used for cold forging. What features do such units have will be discussed in this article.
Selection of tools and materials for forging. Tips for beginning metal artists. Description of the forging process, features and warnings.
The main working force required to deform the material will be taken by the support, so the base of the future machine must be strong. An I-beam or a pair of channels welded together are suitable for this purpose. Stability of the base will be added by paws made of a similar profile, welded to the overall structure. Next, you can start making other components - the tailstock and spindle.
In each of the components of a homemade cold forging machine with your own hands, the cartridges intended for placing workpieces in them must have strong screw clamps (for the purpose of reliable fixation). Due to the reduction in the length of the workpiece when twisting, the tailstock is always sliding. It is possible to construct a headstock from a vice, securing them to the base with bolts of a standard size of at least M16. On the same axis with the clamping unit, a bushing is installed for the moving part of the machine, in which holes for the clamping bolts are pre-drilled.
The moving part of the spindle is rotated by a handle consisting of 4 levers, which are of sufficient length to absorb the force applied for rotation. You can add rubber grommets to protect your hands from slipping.
The main difference in assembling a universal homemade cold forging machine is the design of the moving part. It should provide for screw feed when making lanterns and baskets and be fixed during normal twisting of the metal. Therefore, the moving part is equipped with a set of two spindles - smooth and screw. In this design, the sliding headstock requires a locking screw for fixation.
Helpful advice! If it is necessary to make a workpiece that is not twisted along its entire length, but only in certain areas, limiters are added to the design of the machine. They are made like a tailstock - with screw clamps and the ability to slide.
Working on a torsion bar machine is physically tiring; obtaining high-quality products in large volume difficult. Therefore, introducing an electric drive into the design would be an appropriate solution.
How to make a cold forging machine
The bending machine is monumental, massive, simple in design and assembly, but difficult to find and fit parts. Its purpose is to bend under different angles workpieces, so the force on all components will be equally large, which means that the requirements for assembly parts are high.
A thick steel frame is selected for the base of the machine. It is worth considering that the machine will be mounted on a table. Usually the fasteners are made with a bolted connection, for example, like a vice. There is a guide in the center of the frame that will be movable. It is driven by an eccentric mechanism, which, in turn, is fixed to the base frame. Additionally, three stops are installed, creating a kind of “fork” - these are the working elements of the structure. Depending on the bend profile, they are changed: round rollers - for making waves, “hammer” - for forming corners.
Working elements are made only from structural steel. Their strength is the reliability of all equipment. Processing and fitting similar products require exclusively professional equipment. Therefore, if there are difficulties in ordering, purchasing or manufacturing the main components, then it would be advisable to buy a machine for cold bending forging in a store. Its cost is low, but it can be additionally useful for bending pipes.
Do-it-yourself snail machine for cold forging: design options
The algorithm for assembling a homemade cold forging machine with your own hands is quite simple and understandable. Only when creating a snail, three variants of the design idea are possible, and even then very approximate. Each master sees the execution of a curl or spiral, as well as the sequence of bending the workpiece in his own way.
Like anyone creative process, making a snail for cold forging with your own hands begins with the basics - designing the key components of the machine. Applied to this case– this is a frame, a table top and a main shaft with a rotation lever.
The frame or table for the snail must be made of metal. Wood is completely unsuitable for this design: prolonged and heavy loads will destroy it after several uses. The material used would be a corner, thick-walled pipes or a channel. For the tabletop you will also need metal - a sheet with a thickness of at least 4 mm: the thicker, the more reliable. The shaft and lever are the main assembly that will force the metal workpiece to bend according to a given pattern. The lever is connected on one side to a roller that bends the workpiece, and on the other to the main shaft.
According to the type of design, snail machines come in three variants:
- monolithic with a fixed bending template;
- with removable bending structures that allow you to create different types of curls;
- with collapsible curl designs and a rotating tabletop for obtaining complex bending profiles of great precision.
Drawings of a cold forging machine for a snail with your own hands
Many craftsmen who take on the manufacture of machines for the first time neglect the design stage, build templates “by eye”, and develop and modernize components directly during the assembly process. A drawing of a snail for cold forging with your own hands should be done at the preparation stage. It will help to avoid some subtle nuances during assembly, and will also significantly reduce the manufacturing process time.
It is not necessary to follow the drawings made by another master. Availability of manufacturing materials or assembly conditions may vary, and it is likely that the vision finished design may also be different.
One of the design options :
1 - snail ploughshare; 2 - base of the machine; 3 - pressure roller; 4 - lever for controlling the pressure roller; 5 - fastening the base; 6 - finger for fixing the plowshares; 7 - groove for the pressure roller; 8 - control lever axis; 9 - spring for pressing the roller; 10 - clamp for the workpiece; 11 - driving ploughshare of the snail; 12 - main axis; 13 - levers
Diagram of a snail machine for processing products using cold forging
A drawing is especially important for constructing curl patterns with your own hands. A video of cold forging equipment will help you correctly calculate and build a proportional spiral. This stage is necessary so that the curl made on a homemade machine has an aesthetic appearance.
Helpful advice! Templates for the snail are built according to the rules of mathematical spirals, taking into account the number of turns, their density, the width of the opening for equipment on the machine and the initial radius of the entrance to the curl.
Making a snail: how to make a machine with your own hands
A monolithic machine is the most simple design snails The spiral pattern is applied directly to the tabletop. Then, following the drawing, several pieces are cut out of thick metal. They are welded to the tabletop, following the previously applied markings. Work on a snail of this type progresses slowly, but the machine allows you to bend both workpieces of symmetrical diameter and strips of metal that are laid flat, without vertical deformations.
A monolithic machine can have Alternative option designs when the base is not made fixed, but can be rotated. A worm mechanism is used for a given rotation and to facilitate physical labor.
How to improve a snail cold forging machine with your own hands
A homemade snail does not have to contain only simple elements. You can immediately assemble an improved model. For example, what to do if curls are needed different forms, and with different patterns of spirals? It would be impractical to assemble a separate machine for each sample. Therefore, instead of a tightly welded single template, a number of removable options with different patterns are created on the tabletop. Adjustments are made to the design that allow you to change the template, secure it stably, while maintaining the overall reliability of the machine.
The most professional of the snail models is a machine where the table top rotates and the curl template is made from several collapsible segments. It is worth noting that all sections are manufactured with high precision. It is difficult to implement this in a home workshop, so the production of the unit is ordered in workshops or at a factory. The curvature of the template is changed using adjusting screws, and a number of holes are made on the surface of the tabletop that will fix the template segments in a given position. You can bend any type of curl using this method.
Making a cold forging machine with your own hands, the drawing of which will help you complete this task, is quite simple if you understand the principle of its operation and design features. It is important to calculate everything carefully and take measurements. It is possible that someone will be able to come up with their own new options or improve existing models.
Homemade machines for cold metal forging with your own hands: video instructions
Cinder block – modern variety building material, which is rightfully considered one of the most convenient for use in the construction of small residential or non-residential buildings.
Such blocks are excellent heat and sound insulators, as a result of which they are widely used in modern construction residential buildings in order to improve the operational properties of houses.
Like any other building materials of similar purpose, cinder block has quite high cost. To save on the construction of a building using such blocks, you can make them yourself by making your own machine for producing blocks according to ready-made drawings.
The simplest design of a cinder block machine
The most in a simple way The manufacture of such building blocks is the use of collapsible forms without a vibration mechanism and any other additional elements.
To make blocks in such a primitive machine, you need to prepare a soft solution, pour it into molds and leave for several hours. After this, the mold is disassembled, leaving the cinder block to dry in a free state.
To ensure the presence of voids in the blocks, you can use regular bottles from champagne, since they have fairly thick walls that are difficult to break during such use.
The material for the walls of such a homemade machine for making cinder blocks can be wood or some sheet metal, pre-treated with oil.
Making a more complex machine
More complex design The machine, on which it will be possible to produce cinder blocks, additionally has a vibration mechanism, as well as a device for removing finished blocks from the cinder block mechanism.
It should be noted that this type of building material comes in three main types:
- whole concrete block without voids;
- blocks with voids, the volume of which is no more than a third of the volume of the entire product;
- blocks whose voids make up 40% of the total volume.
Such parameters must be taken into account when creating drawings for making such a machine yourself.
The most popular material of this type is a block with 30% voids. The drawings and design of a homemade machine for the production of just such blocks will be discussed further.
Machine form
First of all, it is necessary to make a cinder block mold, which during the manufacturing process of building materials will serve as a template for future products.
First you need to decide on the size of the material to be produced. Standard option cinder block - 40x20x20 centimeters, but this is not at all prerequisite, you can set the sizes yourself to suit your specific needs and preferences.
For high quality workmanship When making a cinder block with your own hands, the machine should be susceptible to slight vibrations, so the height of the mold for the blocks should be about 5 cm higher than the height of the future block - the concrete will shrink slightly when exposed to vibration.
The optimal form is made from sheet metal at least 3 mm thick. All welds must be placed on the outer part of the form, otherwise they will spoil the form and appearance material.
Next, it is necessary to make special inserts in the mold, which will ensure the presence of voids in them during the production of blocks. For this the best option will use three cylinders with a diameter of approximately 8 cm.
Such elements can be made with your own hands, using any available means, for example, cutting metal pipes.
Elements that will ensure the presence of cavities in the finished cinder block material should be made at a slight angle - cone-shaped: this will ensure ease of removing the finished product from the mold.
To prevent concrete from sticking to the mold walls and pipe sections, their surface must be lubricated with oil before each block production.
Vibration mechanism
To ensure maximum high quality finished material, during the production process the blocks need to be subject to slight vibrations. The presence of a special mechanism for this must be provided at the stage of creating the device drawing. In this case, residual air can be effectively removed from the concrete, and the material will be evenly distributed throughout the entire volume of the form, resulting in final product It will be uniformly dense and durable.
Typically, an electric motor is used as such a mechanism. A bar is attached to the working shaft, in which the center of gravity is shifted. Such a device requires manual adjustment, otherwise strong vibration can splash concrete, and weak vibration will not ensure high quality blocks.
A vibration system of this type is used in all drawings of do-it-yourself cinder block machines - to implement it you can even use an engine from a conventional washing machine with a power of at least 150 W.
To ensure uniform transmission of vibrations, the mold must be protected from sudden shocks using a layer of silicone or rubber gaskets.
Lifting mechanism
Typically, the design of a cinder block machine, made by hand according to drawings, provides for the presence of a special mechanism that will allow you to easily and quickly remove finished goods from the machine. There are a lot of designs for such a device, since each master creates a device for producing such material for himself, using his own available materials and personal preferences.
The simplest option is to weld ordinary handles to the block mold, by pulling which, the almost finished building material can be removed from its shape. Of course, you can come up with a mechanism that is a little more complicated and easier to use.
Therefore, to manufacture a suitable lifting mechanism, you should study existing models of such equipment - both home-made machines and factory ones, and only after that begin to implement your own idea. In this case, you can take the maximum correct solution, choosing the optimal design for yourself.
Thus, using the information provided, anyone can make a machine for the production of standard or standard cinder blocks with their own hands. own design. But to get the maximum quality material, it should be based on a reliable and well-made form, as well as a special installation that will create vibrations.
Cold forging is impossible without special forging equipment. Let's look at the types of devices and the figures that can be obtained with their help. We have prepared drawings and thematic videos for you. We will also consider the sequence of making a cold forging machine with your own hands.
If you are just going to organize a cold forging workshop and want to avoid high expenses, That self-production machines and devices will help you create your own small business without excessive costs.
Basic devices and machines
Cold forging machines are mainly designed for arc or angle bending, as well as twisting. They can be manual or electrically driven.
The main types of machines and devices for cold forging:
- Gnutik
- Twister
- Snail
- globe
- Wave
- Flashlight
Device "Gnutik"
Purchased or made independently, the “Gnutik” is a universal device that allows you to obtain an arc or angle from a rod. It consists of a base with a slider, on which a stop with an angle (90° or another as necessary) and two cylindrical fixed stops are fixed. By moving the slider and the angle stop, the rod bends at an angle. To obtain an arc, a third cylinder is provided, rotating on the side opposite to the angle stop.
The device can be made on a horizontal or vertical platform.
Axonometry of the "Gnutik" device - vertical arrangement
To scale the dimensions, here is a drawing of the bottom bar of this “Gnutik”.

This is what a homemade “Gnutik” looks like:
Twister device
“Twister” is a tool for twisting rods, mostly square, along the longitudinal axis. This simple device can be manual or electric. Operating principle: both ends of the rod are secured, then one fastening begins to rotate, twisting the metal to the required shape.
Appearance of a purchased manual “Twister”
Look at the photo of a homemade “Twister” with an electric drive, assembled using used electrical equipment:
For making “Lanterns” and “Cones” there is special machine, but for starters, you can also use “Twister”, as shown in the video (English, but everything is very clear).
Video: how to make a blank for “Flashlight” on “Twister”
Device "Snail"
The Snail Tool is designed to create curls (or spirals) and “currencies” (S-shaped pieces). There are various designs.
One of the design options: 1 - snail ploughshare; 2 - base of the machine; 3 — pressure roller; 4 — lever for controlling the pressure roller; 5 — fastening the base; 6 — finger for fixing the plowshares; 7 — groove for the pressure roller; 8 — control lever axis; 9 — spring for pressing the roller; 10 — clamp for the workpiece; 11 — leading ploughshare of the snail; 12 — main axis; 13 — levers
The result should be something like this:
Another one lightweight design to bend rolled products with a cross-section up to 12 mm:
1 - cochlear segment; 2 - eccentric; 3 - handle; 4 - base; 5 — guide runners; 6 - axis; 7 - slider; 8 — axle nut; 9 — roller mounting axis; 10 - roller; 11 — drive axis; 12 — eccentric guide; 13 - central segment of the cochlea; 14 — eccentric wing; 15 — main leg; 16 — connecting pin of cochlea segments; 17 — adjustment screw; 18 - connecting ear of cochlear segments
Often the “Snail” device is made on a support, especially if you need to bend thick rolled products.
Several useful videos on homemade “Snail” machines.

We will talk more about such designs below.
"Globe" device
Such a device is similar in appearance to a school protractor and is designed for making arcs with a large bending radius from a strip, square, circle or hexagon. First, one end of the workpiece is fixed with a bend, then it is bent along its entire length according to the template. The principle of operation is somewhat similar to the operation of a canning machine.

Making a "Snail" with a drive
The electrically driven "snail" facilitates the production of curls and "currencies". This is especially valuable when the work is not “for the soul”, but for production large quantity similar products on the production line when working to order.
Below are the steps to assemble a rod bending machine maximum cross section 10x10 mm. The 0.5 kW/1000 rpm engine operates at the limit of its capabilities. Performs 6 shaft revolutions per minute. The snail segments are machined from a round blank St.45 without heat treatment, 25 mm high and 20 mm thick. The volute is mounted on a shaft on bearings from the rear wheel of a motorcycle - 7204. The support roller is firmly fixed in the groove. Pulleys are installed between the engine and the gearbox.
Below are drawings of the cochlea segments.

Snail centerpiece
For a more massive rod (from 12 mm), the motor power should be more than a kilowatt. The photographs below show a machine with a 2.2 kW, 1000 rpm motor, giving a shaft output of about 10 rpm. This is already a machine for professional use. A used gearbox was used, the matrix was cut from a 30 mm thick workpiece - the most labor-intensive process.
For cold forging you will also need an anvil and a hammer. A forge is not needed, it is only required for hot forging.
Advice! Before starting work, draw a sketch future design V life size. This will help you adjust the elements and not get confused during assembly.
On the market building materials presented different kinds concrete blocks, including slag concrete. They are distinguished by their low weight and increased dimensions, which makes it possible to build a building at an accelerated pace. Wanting to reduce the estimated cost of work, many developers do not purchase block building materials, but make them themselves using a machine for producing blocks. Industrial models of vibrating machines are not always distinguished by their quality and performance. Easy to do homemade unit, guided by the recommendations given.
Cinder blocks
Types of concrete blocks for construction
Despite the fact that in construction industry Brick is often used for the construction of buildings; it is difficult for it to compete with block building materials made from concrete. To build a house, it’s easy to choose blocks that differ:
- increased dimensions;
- reduced weight;
- filler used;
- production technology.
The manufacturing technology of block products involves the use of the following filler:
- expanded clay;
- sawdust;
- slags;
- brick fighting;
- dropouts.
Expanded clay blocks Wall materials block type are divided into the following types:
- expanded clay concrete blocks;
- wood concrete products;
- foam concrete building materials;
- aerated concrete products;
- cinder blocks.
The use of cinder blocks, the cost of which is lower than other block building materials, reduces the cost of building construction. Making cinder blocks on your own is easy to do at home, using a machine for producing blocks. Let's consider the characteristics of cinder block building materials.
Cinder concrete blocks - properties of building materials
Cinder concrete blocks are a building material produced using vibration pressing technology. Along with cement and sand, the following types of filler are used for production:
- slags, which are waste from metallurgical enterprises;
- granite and crushed stone screenings;
- brick waste;
- river crushed stone;
- expanded clay particles.
Brick waste is one of the components for cinder blocks The production of cinder block products can be carried out in various ways:
- using industrial technology, which involves heat treatment and steaming;
- at home using homemade machine for blocks.
By producing cinder blocks on a block making machine, you can obtain products that have the following advantages:
- elevated thermal insulation characteristics. Slag concrete has low thermal conductivity and retains heat well;
- increased dimensions. They allow you to quickly build a cinder concrete building, outbuilding or garage with your own hands;
- resistance to microorganisms and damage by rodents. This is ensured by the filler used and the structure of the cinder block mass;
- reduced cost. Homemade cinder block cheaper than, for example, foam blocks used for construction purchased in a retail chain.
In addition, slag concrete material is fireproof, easy to process and dampens external noise.
Along with its advantages, slag concrete has a number of disadvantages:
- limited service life. The durability of a slag concrete structure does not exceed two and a half decades;
- reduced strength properties. Only one-story and two-story buildings are erected from cinder concrete;
- cracks when sheared. During the shrinkage of the box, cracks do not occur along the seams, but directly along the blocks.
Cinder concrete has low thermal conductivity and retains heat well Slag concrete also has an unpresentable appearance and needs exterior decoration. In addition, cinder concrete cannot be used for foundation construction.
Despite weak sides material, it is preferred in situations where it is required for minimum costs quickly build a small building or outbuilding.
Which is the best block machine to use?
Developers who decide to independently produce cinder blocks for the construction of walls are faced with the question of choosing equipment. It is not always possible to rent a machine for the production of building blocks, especially in small populated areas. Many people decide to make the equipment themselves. Depending on your financial capabilities, you can choose the following options:
- simplest design that allows you to make it at home wall blocks at minimal cost;
- a modernized version of the unit, equipped with a compaction device and additional mechanisms.
It is difficult to give a definite answer as to which block production machine is preferable to use. It all depends on the number of blocks that need to be produced and financing opportunities. Let us dwell on the features of each unit.
Simplified block machine
To make cinder blocks on your own in a reduced quantity, it is not necessary to make a mechanized unit, use a vibrator, or additional mechanisms. The manufacturing process using simplified technology can be carried out in special forms.
Simplified block machine Procedure:
- Assemble the molds and coat their inner surfaces with waste oil.
- Pour cinder block mixture into collapsible molds.
- Leave for 3-4 hours until the solution hardens.
- Disassemble the containers and carefully remove the blocks.
- Allow to dry indoors.
If it is necessary to produce hollow products, it is advisable to use ordinary drink bottles to form cavities. A simplified machine for the production of blocks, which is a container of the required size made of wood or steel, can be manufactured at a minimum amount of cost.
Modernized machine for the production of building blocks
With an increased need for cinder blocks for the construction of a large building, you can make a more complex machine for producing blocks, equipped with special devices:
- vibration mechanism. An electric motor is used as a vibration motor, with an eccentric located on the drive shaft. The drive power depends on the size of the mold, the mass of the slag concrete solution and is 0.5–1.5 kW. Under the influence of vibration, the slag concrete mass is compacted, the material is evenly distributed throughout the entire space of the mold, and air inclusions are removed. As a result of compaction, the specific gravity and strength of cinder block products;
- lifting device. It is designed for faster extraction finished products from molding containers. There are many constructive solutions, allowing to speed up and facilitate the removal of blocks. In the most simple version It is enough to weld handles of any shape to the molding container, by pulling which you can remove the hardened block. Using ready-made drawings, you can independently assemble a lever mechanism from scrap materials.
Upgraded machine for the production of building blocks The shape used in this unit must correspond to the size of the cinder block that is planned to be made. In most cases, products are manufactured of standard dimensions - 0.4x0.2x0.2 m. The molding container must have a height increased by 4m5 cm so that the molded block after compaction has the required dimensions. To simulate cavities, pipe scraps of the required diameter can be welded to the bottom of the container.
We make a machine for blocks with our own hands - sequence of actions
To perform work on assembling the vibration compactor, it is necessary to prepare. Will be required following materials and tools:
- steel sheets 2.5–3 mm thick;
- metal pipe with an outer diameter of 7.5 m 8.5 cm;
- electric motor with a power of up to one kilowatt;
- apparatus for electric welding with electrodes;
- grinder complete with cutting wheel for metal;
- locksmith tool.
Before production begins, you should prepare drawings and understand the design of the machine for producing blocks. It is necessary to decide on the dimensions of the blocks that will be made - the size of the mold depends on this. It can be welded to fit standard products or made in larger sizes.
Drawing of a cinder block machine When everything is prepared, we make a machine for the production of block products, observing the sequence of operations:
- Cut from steel sheet blanks rectangular shape for welding a molding container of the required size.
- Tack them with electric welding and assemble the side edging of the molding box for pouring the cinder block mixture.
- Check the correct tack when equal to length diagonals, finally weld the mold elements.
- Slice tubular blanks, the length of which is equal to the height of the form and make diametrically located cuts on the side surface.
- Provide a conical shape for the tubular elements and weld them to bottom sheet future molding box.
- Weld the crossbar to the cones, install plugs on the ends with a smaller size.
- Produce final assembly molding box, welding the bottom with inserts to the edging.
- Attach two handles on opposite sides to lift and transport the molding container.
- Install the threaded elements for fastening the vibration motor and screw the vibration motor with the balancing weight.
- Cut out the top cover that matches the dimensions of the inner cavity of the box and has holes for pipes.
- Apply anti-corrosion coating, assemble the unit and check its operation.
The use of a group container of increased size allows to increase the productivity of the vibropressing machine.
Drawing. Vibroforming machine Self-production of slag concrete blocks - recipe
Do-it-yourself cinder block making machine To make cinder blocks using self-made equipment, you need to prepare the following materials:
- Portland cement marked M400 and higher;
- screenings or small crushed stone;
- slag or ash from coal combustion;
- sifted sand;
- water.
Special plasticizers are also used to increase the strength of the cinder block mass and accelerate hardening. To prepare an increased volume of slag concrete mixture, a concrete mixer will be required.
The following slag concrete compositions are used:
- mix Portland cement with slag in a ratio of 1.5:8. Gradually dilute the mixture with water, the amount of which should not exceed half the volume of cement;
- mix crushed stone screenings, cement and coal ash in a ratio of 4:1:4. Add water to the concrete mixer until the solution becomes plastic.
Possible formulations include the use of granulated slags, plasticizers, quartz sand and brick fighting.
Portland cement marked M400 We manufacture products ourselves using a block production machine
Using a self-made machine for blocks, carry out work according to the following algorithm:
- Place the equipment on level ground.
- Connect electrical power.
- Prepare cinder block mortar.
- Pour the prepared mixture into the mold.
- Turn on the vibration motor for 2-3 minutes.
- Add cinder mixture to the top level.
- Place the protective cover and turn on the vibrator.
Compact the array. The cover should come into contact with the stops located in accordance with the height of the block. Then remove the box and let the molded block sit until the mass sets. After careful removal, dry the cinder concrete products in a closed and ventilated area.
Let's sum it up
When planning the construction of a building made of cinder concrete, you can reduce costs by independently making a machine for producing blocks. It is important to use verified documentation for the manufacture of the unit and carefully understand the design of the vibration compaction device. To obtain high-quality products, study the recipe and also understand the technology.
