Abstract

This invention relates to a device for filling molds with powder. The aim of the invention is to improve the quality of the sleeve sleeve type products. The cassette 1 falls asleep powder into the cavity of the matrix and is retracted. When a compressed product is pushed together, the transport device 5, designed as a U-shaped gripper, fits under the sleeve of the sleeve and carries it through the die cavity. In the course of the further movement of the cassette, the interrupter 12 is pivotally mounted on the guide columns 11, and during the reverse course of the cassette it returns to its original position, excluding the possibility of the product re-entering the pressing zone. The device provides the removal of products of the sleeve type with a collar from the pressing zone without their destruction. 4 il. J 2 (L с: к сою ч 11

Description

The invention relates to powder metallurgy, namely, devices for filling the cavity of the mold with powder, mainly in the pressing of shaped articles, in particular bushings.

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

FIG. 1 shows the proposed device in the initial position of supplying the gripper under the collar of the sleeve for transporting the product from the pressing zone with subsequent filling of the powder into the mold cavity; in fig. 2 is a section A-A in FIG. one; in fig. 3 - the device at the time of the return stroke, at which the product is cut off from the transport device; tfa of FIG. 4 is a section BB in FIG. 3

The device for filling the mold contains a movable cassette 1, into which a nozzle 2 is inserted for feeding powder with a flexible hose. On the front wall of the cassette 1 is rigidly fixed by means of the plate 4, the transport device 5, crammed into a U-shaped grip. The device is installed on the matrix plate 6, which includes the matrix 7, the lower punches 8 and 9 rod 10. On the plate 6, the direction of column 11 is set, on which the cutter 12 is pivotally mounted

The device works as follows.

A cartridge filled with powder through | nozzle 2 and a hose 3 moved eircH across the matrix plate 6, causing the powder to fall asleep in the cavity of matrix 7. Then the cartridge is retracted. The powder is then compacted with punches. At the end of the pressing cycle, the pressed product is pushed out of the cavity of the matrix 7 by the lower punch 9, which is flush with the matrix 7. As the cassette 1 moves forward, the transport device 5 fits under the pressed bushing and transfers it through the annular cavity formed by the matrix 7 and the punch 8 Thanks to that, when driving

the cassette 1 not only pushes forward, but also maintains the pressed product with the transporting device 5, the product does not tip over into the annular cavity and

subject to destruction.

During the further movement of the cassette 1 forward, the cutter 12 is deflected, and during the reverse course of the cassette 1, it returns under the action of its own weight

to the starting position. Once behind the colliding product, the slam-shut 12 excludes the possibility of the product re-entering the pressing zone. Then the cycle repeats.

The proposed device provides for the removal of sleeve-type products with a collar from the pressing zone without their destruction.
