(54) PRESS-FORM FOR THE MANUFACTURE OF PRODUCTS OF P-SHAPED PROFILE

(crazy pneumatic mold drive circuit.

On the base 1 of the mold, there is a punch 2, an air distributor 3 and a bending cylinder 4 with a matrix 5 fixed on its stem, carrying the rod 6. In the upper part of the frame 1 there is a valve 7, and pneumatic chambers 8 are mounted on the side racks pressure torus 9, throttle 10 and side pressing cylinder 11. Air chambers 8 with rods} 2 and hinged pillars on the uprights of base 1 levers 13 with rollers 14 form direct pressing amplifiers ./ On the matrix 5, contact strips 15c / gasket are installed 16. A check valve 17 is connected in parallel to the throttle 10, and a reverse valve 9 is connected to the pressure regulator 18. Between the arms 13 t ", the lateral columns 1 have springs 19. The conical head 20 is fixed to the stem of the lateral pressing cylinder 11.

Works mold in the following way. On the punch 2, which is installed on the bed 1, put a package of glued veneer. The air distributor 3 is turned on. The bending cylinder 4 lowers the die 5, the package bends.

The rod 6 fixed at the matrix at the end of the matrix stroke turns on valve 7. Compressed air enters pneumatic chambers 8 direct press amplifiers and through pressure regulator 9 and throttle 10 into the piston cavity of the lateral pressing cylinder.

The rods 12 of the non-cam 8 act on the levers 13, which, by turning, use rollers 14 to press the contact strips 15 mounted on the die and adjustable in height with the help of the spacers 16.

There is a pressing of media of his section of the package. Due to the adjustment of the throttles 10, the rod of the lateral pressing 11 moves with a delay, the opening of the sidewalls of the punch 2 and the pressing of the lateral sections of the package occurs after the middle section of the package is pressed. Depending on the . the shape of the product the pressure on the side parts is regulated by means of the pressure regulator 9.

At the end of the pressing time, the reshar ne {connects the air distributor 3. Compressed air is supplied, the rod cavity of the iybany 4 cylinder and the side pressing cylinder 11. The piston bending 4 through the air distributor 3 communicates with the atmosphere. The piston cavity of the side-pressing cylinder 11 through check valves 17 and IS. valve 7 and air distributor 3 communicate with the atmosphere. The cavities of the pneumatic chambers 8 through the valve 7 and the air distributor 3 communicate with the atmosphere.

The levers 13 under the action of the spring 19 come to their original position. Side press cylinder rod. The vanilla 11c with the tapered head 20 is lowered, the pressure on the side jniacTKH products is removed, allowing

the matrix 5 to rise to its original position. I

When the valve 7 is turned off, the residual compressed air from the pneumatic chambers 8 and the piston capacity of the side-pressing cylinder 11 is released into the atmosphere directly through the valve 7. The mold opens, the finished product is removed, the operating cycle repeats.

Claims (2)

1. Press-form for the manufacture of products of U-shaped profile according to ed. St. N 361871, that is, so that, in order to simplify operation and maintenance of the mold, it is equipped pneumatically driven, including bending, side pressing cylinders and direct pressing amplifiers made in the form of pneumatic chambers and levers with spring return mounted on the side racks and rollers that interact with the contact bars mounted on the die and height-adjustable. 2. Press-form; according to claim. 1, characterized in that. that, in order to automate the process of pressing and ensuring uniform distribution of pressure on the surface of the product; the cylinder of the side press is equipped with a throttle and pressure regulator. 1 Fie.2
