Cinder block is a very convenient building material for the construction of residential buildings of small floors. Many home masters who have free time and the desire to make building blocks on their own try to make a cinder block machine. You can also follow their example, but first you need to familiarize yourself with the features of the equipment, as well as prepare all the necessary materials and tools. As a result, it will be possible to obtain ready-made blocks of cement, granite slag and other fillers, which act as excellent heat and sound insulation. Making cinder blocks is sometimes justified and profitable, which is especially true if you are limited in money.
The device of the machine for cinder blocks
You can do the cinder block machine yourself. If you want to use the simplest method, you can use collapsible forms without a vibrator. For the manufacture of blocks in such forms, a softer solution should be used, to which a slightly higher water content is added. If you want a more advanced device, it is best to add a vibrating device to the machine. With the help of one unit of such equipment, a huge number of blocks can be manufactured without waiting for the moment of concrete setting. This is due to the fact that the solution is used more thick and with little shrinkage.
There are two options for such installations, the first of them provides for the use of a vibrating table, while the second provides for a form with a center of gravity displacement on the shaft. The second method is more preferable, since there will be no need to turn over the mold, as a result, you only have to remove the formed concrete block. The cinder block machine can be made of a molding box, which is a matrix, it should not have a bottom and a vibrator on the side wall. The box is equipped with handles, and after the formation of the product is easily removed without damaging the shape of the mold.
It is possible to make such a variant of equipment in which there will be two interchangeable sets of pressure plates. The equipment should be supplemented with round or rectangular hollow core formers. If you want to make cinder blocks, the dimensions of which will be 390x190x188 mm with a 30% void or less, then for the manufacture of the matrix you should use 3 mm sheet metal, which is cut to the shape of the cinder block. In this case, leave a 5-cm margin for tamping.
The craftsman should form a through box without a bottom, and the welds must be placed outside so that the metal does not “lead”. To the box for greater stability from the end sides, you need to weld the trims from the profile pipes of a small section. A rubber upholstery is made around the perimeter of the base of the matrix, this will protect the lower edges of the matrix from deformation. In order to exclude spillage of the solution, it is necessary to form a bordering apron and attach handles.
How to make a cinder block machine yourself: preparing tools
In order to carry out a cinder block machine, it is necessary to take care of the availability of the following tools:
- Bulgarian;
- locksmith tool;
- welding machine;
- vise.
This entire set will be needed for the manufacture of the matrix, it acts as the main part of the equipment and should have the form that the blocks will have. We should not forget about the presence of voids in the matrix, the last of which is an important part of the machine.
Preparation of materials
In order to perform the work, you will need a sheet of metal, a steel pipe, steel strips, an electric motor and fasteners. The metal should have a 3 mm thickness, and its size will be 1 m 2 . The steel pipe should have a length of 1 m, and its diameter can vary from 7.5 to 9 cm. Steel strips should have the main thickness of the metal, while their length should be 30 cm. The power of the electric motor should not exceed 0.75 kW. You will need fasteners in the form of nuts and bolts.
Machine Instructions
Before making a cinder block machine, you must determine the future dimensions of the product that will be used for construction work. There is an option that provides for the measurement of the finished unit of industrial production. From a metal sheet, it is necessary to prepare the side elements of the machine in the amount of 2 pieces. Between them will be partitions in such a way as to get a box. It must have two equal parts. In the voids, you should leave the bottom wall, the minimum thickness of which will be 3 cm. This will determine the height of the cylinder, which will limit the voids.
The pipe should be divided into 6 parts, the length of each of which will be equal to the height of the voids. In order to make each cylinder in the form of a cone, it is necessary to make incisions of each to the central part, and then squeeze with a vice and weld with a welding machine. The size of the diameter will be 2 mm smaller.
Methodology
If you decide to make a cinder block machine, then the cylinders must be welded on both sides, they are interconnected by the long side of the block. They should be arranged in such a way that the formed voids accurately copy the voids of industrial production. 3 cm plates should be added to the extreme sections, in which a hole is made to fix the eyes on the surface.
In the central parts of the matrix compartments, a surface should be sawed by welding eyelets to it. They are necessary to enable temporary fastening of the stops. As a result, it will be possible to obtain a mechanism by which you will form monolithic blocks or products that will have voids.
Specialist recommendations
When a cinder block machine is made with your own hands, one transverse wall must be used for welding bolts in an amount of 4 pieces. They will act as fasteners for fixing the engine. In the pouring side of the solution, you need to weld the parts in the form of blades and an apron. All components must be cleaned and polished in order to subsequently paint them. At the next stage, a press is made, the shape of which will be the same as the mechanism itself.
For its manufacture, a plate is needed in which correspondences of a slightly larger diameter are made in comparison with the cylinder. The difference is 4 mm. This element should easily be located in the box at a height of 5 cm or more.
Final work
Once you know what the cinder block machine is, you can do it yourself. In order to provide more convenient work with the press, handles should be attached to it. All components of the mechanism must be treated with an anti-corrosion compound, only after the surface dries can it be possible to proceed with the installation of the engine. The next step is to check the system’s health. In order to make a vibrational motor out of a conventional electric motor, it is necessary to install eccentric bolts on its shaft sections. They must coincide in the axial space. When making a home-made cinder block machine, it is important to remember that the type and speed of vibration will depend on the intensity of the fastening of the fasteners.
Slag Block Solution Information
The machine you made can be used to make cinder blocks of different compositions. For this, claydite concrete, sawdust concrete or clay can be used. A standard mixture usually consists of a certain volume of filler, an equal amount of cement and 3 parts of slag waste. An important role is played by the moisture coefficient, which will be contained in the finished mixture. To determine the optimal volume, you should examine the composition, it should not fall apart, while maintaining elasticity and good shape retention.
Cost of machines
If you want to buy a used cinder block machine, then you will have to pay about 6,000 rubles for it. But new machines are much more expensive, sometimes their cost reaches 50,000 rubles.
Conclusion
Now you know how to make a cinder block machine with your own hands. However, it is important not only to execute it correctly, but also to learn how to use it. Before the first loading of the solution, it is necessary to lubricate all contact planes with oil, in which case the solution will stick less. The vibrator can turn on at any stage, but it will be most effective to use it before pressing begins. It is important to take care of the reliability of the electrical insulation of the engine, the apron should be positioned so that it covers the motor from ingress of the mixture.
