Description

12

The invention relates to the construction industry and can be used in the manufacture of products from concrete mixtures by pressing.

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

Fig, 1 shows a device, a view in plan; figure 2 - section in figure 1; on fig.Z - the location of the form iodine press; 4 is the same after the extrusion is finished; FIG. 5 is a section BB in FIG. in fig. 6 - 40, at the time of the end of stripping.

The device consists of a rotary body 1 with matrices 2, a post 3 for laying the mixture, a press 4 and a post 5 for demoulding. A bunker 6 and a lift 7 of the pallets 8 are mounted at the mixing station, and the press 4 is made in the form of a support table 9, a drive 10 and a poin. 11 “fixed on it.” The rotary body around the perimeter of each matrix 2 is hinged. Tray grips 12 for pallets 8, carried out with cams 13. At the dismantling post, an ejector 14 with a drive 15 is installed, which is equipped with vertical rails 16, with bevels at the free ends that come in contact with the bevels of the cams 13 at dismantling 13. A receiving ejector is mounted under the ejector. 17 of the article 18 th,

The device works as follows.

At the post 3 on the lift 7 stack the pallet 8 and by means of the drive lift lift. When this pallet, pressing the bevels of the L-shaped grippers 12, removes them. After pressing the pallet to the matrix 2, the pallet 8 is grasped with L-shaped grippers 12. Then the concrete mixture is placed in the matrix 2 and the casing is rotated one step by placing the filled matrix under the punch 11, pressing the product 18 (Fig. 4). Fill the following matrix with concrete mix. After the extrusion is completed and the concrete mixture is placed into the next matrix, the housing 1 is turned to the next step, the matrix 2 is installed with the compressed product at the formwork post under the ejector 14 (FIG. 3). Then, turning on the actuator 15, lower the ejector 14, which bevels with the vertical rails 16 and interacts with the cams 1 3 and lifts the L-shaped grippers from under the pallet 8 (Fig. 6). After this, the bottom 17 and the ejector 14 are synchronously lowered down j laying on, with the products on the bottom or on the product previously laid on it. Then, the ejector is raised to the upper position, and the process is repeated.
