DIY cinder block machine: drawings, photos

If you are interested in the question of the maximum cost reduction of building materials, then you can think about how to make a machine for cinder blocks with your own hands. This can only be done using a vibrating machine. Of course, it is possible to purchase such equipment, but it is quite expensive, and will be justified only if you want to put the molding of products on stream. That is why experts advise you to make a matrix yourself, but you can read about the rules for carrying out these works below.

You can make a machine for the production of cinder blocks with your own hands yourself. Cinder block act as the most affordable and simple stone material for walling. It was invented more than 100 years ago, the combination of the characteristics of this insulating and structural material makes it indispensable today. The development of mass private construction, especially with regard to farms and subsidiary plots, requires a constant reduction in the cost of constructing non-residential premises.

For the construction of pantries, sheds and cribs today, almost everything that comes to hand is used. If you want to do the work with the help of high-quality products, then you can make a cinder block machine yourself.

Technology of work

You must understand the moment that the final product, made with a homemade machine, will not have such high durability and strength as blocks of factory production. This is due to the fact that home production cannot afford to withstand all the rules and features of the technology, because you will not be able to use the steaming stage, which saturates the material with the necessary moisture. However, self-made blocks can be used for the construction of light one-story houses. Their service life will be 30 years.

If you decide to make a machine for cinder block, then keep in mind that the main part of such equipment will be the mold for the raw mix, or matrix. These parts are a steel box in which elements in the form of voids are installed. The matrix is ​​a machine that can be used to perform a certain stage of operations manually.

Preparation of materials and tools

In order to make a machine for cinder block, you should stock up on a grinder, metalwork tools, a welding machine and a vice. You will need a 3 mm steel sheet, the size of which will be 1 square meter. Prepare a 3 mm strip with a width of 0.3 meters. Nuts and bolts will act as additional components. Be sure to stock up on a pipe, the diameter of which can vary from 75 to 90 millimeters. Its length should be equal to one meter. You will need an electric motor, the power of which can vary from 500 to 750 watts.

Work procedure

If you decide to make a machine for cinder block on your own, you have to comply with the technology. At the first stage, it provides for the need to determine the dimensions of a standard cinder block. The master must take into account the necessary dimensions for the future product. The side parts of the matrix are cut out of the sheet, and you need to expect that for 2 blocks you will need a structure that will be equipped with a partition in the center. Thus, you should get a kind of box in which there will be two compartments. Voids should provide this wall, the thickness of which is at least 30 millimeters. Given this, you need to determine the height of the parallelepiped or cylinder. This will limit the void.

Equipment manufacturing technique

If you decide to make your own machine for the cinder block with your own hands, the drawings of which are to be prepared in advance, you need to cut the pipe lengths in the amount of 6 pieces. Their length should be the height of the cylinder.

In order to give the cylinders a cone shape, it is necessary to cut each element along to the central part, and then squeeze it with a vice, connecting with a welding machine. This will reduce the diameter by 3 millimeters. Cylinders are welded on both sides. Connect them together will need to be in the form of a row on the long side of the future product. It is necessary to make cuts in the center of each of the compartments of the fabricated matrix, and then strengthen the eyes on the back side. This is required for temporary fixation of the void limiters, which will enable one to produce blocks.

Expert Advice

When a cinder block machine is made by oneself, drawings must be considered before the start of work. On one of the transverse walls you need to weld 4 bolts for the mounting holes. Blades and an apron are welded along the edges. All parts are polished and cleaned so that they can be painted afterwards.

At the next stage, the master makes the mold. This element is a plate with holes, the diameter of the latter should be larger than the cylinder by about 5 millimeters. It is important to make the plate so that it freely immerses to a depth of 70 millimeters in the box where the stops will be.

Handles are attached to the press, which will be convenient to use during the operation of the equipment. The whole structure is painted at the next stage, and after that the vibromotor is installed.

What else needs to be considered when manufacturing

In order to convert a conventional electric motor, turning it into a vibromotor, it will be necessary to add eccentric shafts onto it, which are welded in the form of bolts. Their axis must necessarily coincide. The nuts are tightened onto the bolts, and it is important to select the vibration frequency and amplitude. If you make such a matrix, then it will act as the basis for a walking or stationary machine. If you want to upgrade the design, then you will need the skills of a locksmith.

Material for blocks

After the machine for the production of cinder blocks is ready, you can think about what will form the basis of the products. Theoretically, they can be made from anything; claydite concrete, clay, and sawdust concrete are suitable. The most suitable mixture composition is 1 part sand, 3 parts gravel slag and 1 part cement.

The decisive moment in carrying out these works will be the ratio of water in the mixture. No matter how good the slag block making machine is , if the mixture is improperly prepared, the products will turn out to be of poor quality. The water content is easy to determine by eye. The mixture should keep its shape without crumbling. The raw materials fit into the matrix, so that during the pressing process, blocks are obtained. In the manufacture of the machine instead of voids, you can use a brick fight, an acute-angled stone or glass bottles.

Work with the machine

Drawings of the machine for cinder blocks you may well be done independently. It is important to correctly understand the technology that was described above, and also to study the features of working with a home-made device. All contact surfaces before the first loading of raw materials must be lubricated with oil, while the solution will not stick to the metal.
