Description

112

The invention relates to the processing of metals by pressure, namely to mountains; whose die forging.

The purpose of the invention is to increase the productivity and quality of the products obtained. ,

Fig: 1 shows the stamp, the closed position; in fig. 2 - the same, the original position; in fig. 3 - the same; side view; in fig. 4 shows section A-A in FIG. 3

The combined stamp contains a top plate 1 with a punch 2 fixed on it, on which traverse 3 is movably mounted, connected by spring-loaded rods 4 with the top plate 1. The traverse matrix 5 is fixed on the traverse 3, the ejector 6 is mounted in the traverse with ejector beams 6 with bevels , on the traverse wall, on the opposite side of the ejector, there is an opening for ejection of the forging, and there are two projections on the outside of the traverse. On the bottom plate 7, a punch-matrix S is fixed, on which movably the catcher 9 with a window in the form of a forging is mounted, supported on the buffer 10, and also the stops 11 with the possibility of their interaction with the projections of the traverse 3.

The stamp works as follows.

The forging 12 is placed in the safety gear 9: When the press slide moves downward, the traverse 3 with the die 5 touches the forgings with a burr and remains fixed until 5 when the upper plane touches the upper plate 1. With some stroke of the slide of the traverse 3 with the die 5 and the punch 2, the forging is pressed 12 to the punch-die 8, lowering the driver 9. With the further lowering of the slide, trimming by the obstruction matrix 5 and punching the holes by the punch 2 takes place. The inner baling is pushed through the die-punch 8 and falls through the hole in the buffer. When the slide is up, the forging 12 together with the punch 2, and then the yoke 3 with the matrix 5 moves up. Traverse 3, interacting with its projections with the stops 11, stops. Moving upward along with the punch 2, the forging 12 with its side surface interacts with the ejector bevels and retracts the ejectors to the left, touches the traverse 3 with its upper surface of the upper plane of the window, and stops. Upon further movement of the slider, the punch 2 leaves the forging 12, and the forging 12 by the pickers 6 is automatically removed through the crosshead window 3 to the container. The blister remaining on the catcher 9 is removed by a robot or worker.
