Description

1

This invention relates to the manufacture of concrete products and other materials.

The purpose of the invention is to increase productivity and simplify the design.

FIG. 1 schematically shows the device, a general view; in fig. 2 shows section A-A in FIG. one.

The device for forming articles contains a hopper (not shown), a frame 1 on which the molding chambers 2 and 3 are installed, wedge pressing bodies 4, drive pushers 5 mounted on horizontal rods 6. The latter are equipped with a drive for their reciprocating movement in the form hydraulic cylinders 7, a housing 8 for fixing in it the ends of wedge bodies 4 interconnected with each other and fixed 9 and movable 10 stops contacting the pushers 5. Each forming chamber is equipped with a movable chamber 11 with a drive its movements in the form of pneumatic cylinders 12 mounted on rods 6. Each molding chamber and movable chamber 11 cover, using soft joints 12, box 13, equipped with a 14 "agitator

The device works as follows.

At the position of the working bodies, ka is shown in the figures, and at the completion of the earlier process, the movable chambers 11 are in the closed position, and the material pushers 5 are on the support of the frame 1.

At this time, the wedge bodies 4 are in the extreme left position and occupy the initial position in the left chamber, and in the right position the position after pressing the material enclosed in it. The rods 6, moving the hydraulic cylinders 7 to the right, abut against the stops 9 and force the pushers 5 of the right chamber and the casing 8 with wedge bodies 4 to move.

The latter can be carried out with a certain "delay," which causes the material enclosed in the right chamber to be pressed in the longitudinal direction and, consequently, an increased degree of its compaction during the subsequent transverse pressing in wedge bodies. This can be adjusted by adjustable stops 10.

During the reverse movement, the rods 6 are first idle until the stops 9 approach the material 5 pusher of the left chamber and the casing 8 on the other side. During this time, another portion of the material will flow in the right chamber as a result of the removal of the pneumatic cylinder 12 11 and retracting the pusher 5 all the way, briefly turning on the stirrer 14 and reversely moving the movable chamber 11 until it closes in with the forming chamber.

After pushing the material in the left chamber and moving the wedge bodies, the molding process continues in the same sequence. /
