Abstract

The invention relates to mechanical engineering, namely, to forging equipment. The purpose of the invention is to improve the convenience and safety of the device. The device contains a rotary platform (P) 1 with a roller table 2 and a mechanism for moving the stamp 9 with a drive 3, stationary tables with roller tables and clamps of the position of the stamp, a stationary support 7. The mechanism for moving the stamp is made in the form of a beam placed on P 1 10 with blocks 11 at the ends located on B 10 with the possibility of moving the carriage (K) 12 connected by means of flexible couplings 13 with P 1. To remove punch 9 from press 6, P 1 is coaxial with support 7 and press 6. 3 B 10 comes out of P 1. At the same time By 12 is moved along B 10 towards the stamp. The stamp 9 interlocks with K 12 and the actuator 3 moves to P 1. Next, P 1 rotates toward the free table and the die moves to the table, K 12 is released from the punch and P 1 rotates towards the table on which the new punch is installed. Install a new stamp in reverse order. 3 il.

To extract the stamp 9 from the press 6, the platform I rotates to align its axis with the axis of the stationary support 7 and the press 6. The drive 3 of the block 10 is extended from platform 1, and the carriage 12 alternates along the beam 10 in the direction of the press. In the extreme position, the carriage 12 interlocks with the punch 9. The reverse travel of the actuator 3 and the punch 9, C (; one with the carriage 12), Mi press fi advances. Since the mechanism for moving the stamp is made in the form of a beam 10 with two blocks 1 1 at the ends having the ability of KOHco.ibHo to move forward by drive 3 from plug-in I. and carriage 12, having the ability to move along beam 10, and n), and this carriage 12 is connected to platform 1 by flexible connections 13, covering beam 10 through B.uki 11, The stamp 9 in one movement is mixed from the press through the support 7 onto the platform 1. Yes, 1 circuit 1 is rotated to rma sovmeshepi to one hundred stationary. sev 4, which is free. (using the .3 P1tamp 9 rotary drive from platform 1 on the roller conveyor 5 CTo.ia 4 and on the front face 14, the clamp 8 is clamped. In this position, the stamp 9 rests on the front part of the supporting utility on the clamp 8, and on the back part of the p (). 1ik roller table. The arising forces of t | h Ш1 between the stamp 9 and the fixture 8 (}) are stamped on the table 4. In those cases, when the stamp is not installed on the lock for some reason, the spontaneous rolling The stamp 9 with ro, 1ganga 5 of table 4 is prevented by nak, the first position of the roller table 5.

Then, P1tamp 9 times1 is united with the carriage 12 and the drive 3, the mechanism for moving the dies is retracted. Platform I turns to

combining with another table 4, on which the chips are prepared for operation. The movement of the stamp prepared for operation to the press is carried out similarly.

In comparison with the known, the proposed device provides a convenient approach both to the press and to stationary tables and a turntable and eliminates the possibility of injury when moving the N1 stamps to stationary tables.
