Description

one

The invention relates to equipment for the production of hollow bricks with semi-dry pressing and can be used in the building materials industry.

The closest technical solution is a press for semi-dry pressing of hollow silicate brick, containing a frame, a turntable with press-forms installed in it, and hollow-forming machines with a mixed drive, 1.

However, the products obtained at a known press have insufficient voidness, not higher than 8-10%, since the drive of the void-forming agents is not able to absorb considerable forces from the latter and they are pushed out of the mold during the pressing of the brick. As a result, the required depth of voids is not achieved, which reduces the quality of the products.

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

The goal is achieved by the fact that in the press for semi-dry pressing of hollow bricks, containing a frame, a turntable with molds installed in it and hollow-forming machines with a stirring drive, the latter is made in the form of two opposedly

power cylinders and crank mechanisms, kinematically connected with them and interacting with hollow cores.

5 In FIG. 1 shows the proposed press; in fig. 2 shows section A-A in FIG. one.

The press contains a bed 1, a rotary table 2 with molds 3 installed in it, a traverse 4, an actuator (not shown) with a gear wheel 5 on which a cam 6 is fixed, which is a strip with a bevel, curved along the circumference; corresponding to the central angle, on which the gear rotates during the time from the moment table 2 stops to the end of pressing. On the base 1 there is a four-way valve 7 and an auxiliary valve 8, the roller of which

20 is in contact with the cam 6. The drive for moving the formers comprises a frame 9, which is mounted on the cross member 4 and on which the supports 10 of the cranks 11 and the power cylinders 12 are mounted, the drive 25 SCH the cranks 11 in motion. The connecting rods 13 are connected to the rod 14 of the nustooobrazovateli through the crossbar 15, the purpose of which is to unload the rod 14 and their guides from the transverse forces.

30 Press works as follows.

Claims (1)

Claim A press for semi-dry pressing of hollow bricks, containing a bed, a 5-turn table with molds installed on it, hollow formers with a drive for moving, characterized in that, in order to improve the quality of products, the drive for moving hollow formers is made in the form of two opposed power cylinders and crank mechanisms kinematically connected with them and interacting with hollow formers.
