Abstract

SUMMARY OF THE INVENTION: device co; holds an individual source of compressed air in the form of a pneumatic cylinder with an overpressure cavity connected to the nozzle, and the rarefaction cavity is hermetically connected to the receiving hopper with a slot receiver. The conical part of the hopper is provided with a hatch closed by a valve through which parts accumulated here are periodically removed. The nozzle and slot receiver with respect to the removed part are spatially oppositely located, and the piston on the side of the rod has a coded check valve, ensuring coordinated operation of the cavities of the pneumatic cylinder (Three movements of the press slide up. 1 ill.

Description

The invention relates to means for mechanizing forging and stamping production and can be used to remove stamped parts from the working area of a stamp and to organize their collection.

A device is known for removing parts from the die working area, comprising an air distributor and a time switch mounted on a fixed base, provided with a parts ejector pivotally mounted on the base and rigidly mounted on the last screen, located opposite the air distributor and receiving another portion of the air coming from it.

Such a device does not provide for the removal of small parts, has a significant intrinsic response time and requires external sources of compressed air.

The closest in technical essence and the achieved positive effect to the invention is a pneumatic blower device for embossing presses containing a slime, a chute, a nozzle, a one-way air valve, actuated by a system of levers from the press slide when moving it upward.

This device, providing removal from the working area of the stamp of small parts such as washers, nuts, flanges, etc., but requires external sources of compressed air; ha, it does not provide an orderly collection of them in the receiving container. The device is not reliable enough to operate.

The purpose of the invention is to increase the reliability of the device when removing the stamped parts from the working area of the stamp and collecting them in a receiving container.

This goal is achieved in that the device for removing parts from the working area of the stamp contains a nozzle mounted on one side of the stamp, an independent source of compressed air in the form of a nozzle connected to the press slider

a pneumatic cylinder, a flexible connecting hose connecting the nozzle to a source of compressed air, an intermediate receiving unit coupled to a receiving hopper connected to a rarefaction cavity of the compressed air source. in case of this, the direct hopper has a hatch valve in the lower part, and the piston of the pneumatic cylinder is equipped with a check valve on the side of the rod. -t-;

The drawing shows the layout of the device. The device according to the invention comprises a cylinder body 1, in the cavity of which a piston 2 is located, connected by means of a rod 3 and an arm 4 to a ram of a mechanical press 5 with the possibility of controlling the stroke of the piston. The piston is equipped with an annular Flat valve 6. The upper cavity 7 of the cylinder body 1 is connected by a flexible hose 8 to the nozzle 9, the second of which is located on the middle of the intermediate receiving unit 10 connected to the receiving hopper 11, which has a lower part of the valve hatch 12 with a counterweight 13, attached to the conical part of the hopper on the swivel 14. By properly sealing the hopper 11 and the lower cavity 15 of cylinder 1 communicating with it, the valve 12 serves to empty the hopper from accumulated parts 16.

The device operates as follows.

When the piston 2 is moved in the cylinder 1 from the action of the press slider 5 upwards, an excess pressure of the medium appears in the upper cavity 7 of the cylinder 1, and a significant pressure is generated in the lower cavity 15 and the hopper 1.1, while the valve 6 is closed. The stamped part 16 from the die matrix (the stamp is not shown) is pushed out by the ejector 17, falling into a narrow zone of high pressure and rarefaction of the medium, and thanks to them is carried away into the slot

receiving node 10 of the hopper 11. In the hopper, the speed of the working medium drops sharply, thanks to which the part settles to the bottom of the hopper. When the piston moves down, it opens

valve 6, noticeably reducing the effect of the reverse movement of the medium in the working area of the stamp; The piston stroke is controlled by the relative position of the stem 3 and bracket 4. Periodic removal of parts from the hopper

produced through the bottom opening of the hopper

11, closed by the valve 12.
