Abstract

This invention relates to multi-stage die forging. The goal is to expand the technological capabilities of the stamp. The stamp is equipped with at least one mechanism for fixing the carriage in an intermediate position. The mechanism is implemented in the form of spring-loaded stops, gates and retainers in the form of stepped rods, which fix the carriage. The stamp allows you to reduce the changeover time when the workpiece is oriented at the machining positions, 1, hp. f-ly, 5 ill.

Description

The invention relates to the processing of metals by pressure, in particular to successive dies for bulk forming.

The aim of the invention is to expand the technological capabilities of the stamp.

FIG. 1 shows the proposed stamp, side view; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. 3; in fig. 5 shows a section B-B in FIG. one ,

The stamp contains 1 plate 2 installed on a shtampa plate with T1 / Zimi 3 and 4 fastened to T1. In guides 3 and A, a carriage 5 with a matrix 6 is mounted. Carriage 5 is connected with part 7.

After this, the power cylinder 7 is turned on and moves the carriage 5 along with the die

The pushers 9 press the steps 16 and the latches 14. The latches 14, together with the stowed support 12, move downwardly, compressing the spring 13. When the latches 14 move downward, the steps 15 exit the grooves 21, releasing the latches 18, which are pushed out of the guides by the action of the springs 19 3 and 4 up to the stop in the step 16. After completion of the stamping, the plate 22 moves upwards, while the stop stop 12 remains in the lower position (below the carriage 5), since the latches 18 fix the latches 14 in steps 16. After the end of the forging, the ram is turned on 7 and moves the car 5 with the die 6 and the pressed billet to the right, to the last position of the punching up to the stops 27. When the carriage 5 moves, the latter slides over the 20 bevels of the latches 18, the latches 18 are recessed, the springs 19 are compressed, the grooves 21 release the latches 14, and the last ones together with the springs -: The stop 12 at the expense of the springs 13 moves upward until the stop 12 rests against the bottom of the slider 5. Stage 15 BHOBij locks the latch 18 in the recessed position. After finishing the Hoi i punching by punch 25, the power cylinder moves the carriage 5 to its original position. When moving to the left, the carriage 5 releases the rest stop 12, and the latter also occupies the initial position.

Next, the punch cycle is repeated.

The proposed stamp can be used not only as multi-position, but also as two-position. For the work of the stamp; as a double-edged one. It is necessary to remove the brackets 8.
