The invention relates to the production of building products by layer-by-layer vibropressing.

The purpose of the invention is to improve the quality of products.

Fig, 1 schematically shows the proposed device; figure 2 - section aa on fig.Z - node

I FIG, 1 | Fig, 4 - node punch

A device for the manufacture of building products by extrusion contains- bins 1 with dispenser 2 ,. under which are located gate valves 3 with a drive for their movement, a matrix 4 with a drive 5, receiving frames 6 installed in two levels with the possibility of movement in the matrix by means of pistons 7 rigidly connected with them, and a punch 8 with a drive 9 movement, In the niches of the pistons 7 are located rolling rollers 10 connected to the rods

II actuator 12 with the help of swivel joints 13, providing self-installation of rollers in the horizontal plane. The punch 8 is made in the form of a main plate 14 and is equipped with coaxially arranged additional plates, 15 of which are intermediate, which are gear-like, and the lower 16 is equipped with a rod with an exciter 17 K made with teeth of the plate 15,

The plate 14 is spring-loaded by means of the spring 19 relative to vibration of the bodies 17 and the plate 15, the rod passes through the hole in the plate 14,

The device works as follows.

The mixture from the hopper 1 is fed into the receiving frame 6 by the dispenser 2, after the hopper 1 is blocked by the gate valve 3. Moving the rolling rollers 10 by the actuator 12, the rolling is carried out and the mixture is distributed in the receiving frame. Then, the lower frame 6 slides onto the movable plate of the matrix 4 while retaining the mixture structure attached thereto. The rolling roller 10, after tacking, is retracted into the niche of the piston 7. The bumping frame 6 also slides over without disturbing the structure of the material placed in it to the downstream until the outlines of their openings completely coincide. With the help of the actuator 9, the punch makes a working movement,

acting on the mixture in the combined frames 6. In the case of manufacturing products of considerable thickness, it is possible that the pressing action is caused by the punch under static pressure of the bottom plate, and after combining the frames 6 - in combination with the vibration action from the vibration exciter 17 and the drive 9. At the same time vibration protection by means of springs 19, through which static pressure is also transmitted. In the case of compaction of the mixture separately in the lower frame 6, followed by compaction in two frames together, the teeth of the plate 15 with the exciter 18 turned off do not create the required pressure on the mixture, and therefore the protrusions on the product at the locations of their location provide the best conditions for adhering two layers of the mixture when pushing upstream frame 6. In this case, vibration exciter 18 is included, which eliminates the lack of static pressure transmitted through springs 19 from drive 9, If desired, it can be A product with a relief surface is obtained, which is ensured by selecting the operating time of the vibration exciter 17 and exceeding or decreasing the height of the protrusions of the intermediate plate 15 with respect to the bottom plate 16 of the punch 8.
