By pulling the pull ring 502, with the assistance of the auxiliary wheel 506 and the main steel wire rope 504, the secondary steel wire rope 505 pulls the positioning rod 503 to move, so that the positioning rod 503 retracts into the clamping block 501, and the upper die 4 can be quickly replaced.
[0022] At the bottom of the punching press 2, there are a connecting plate 3 and an upper die 4. A connecting device 5 is arranged on the connecting plate 3, and a lower die 7, a limiting device 8 and a plate 9 are arranged on the base 6. The plate 9 is lapped on the top of the lower die 7. The limiting device 8 includes a motor 801. The output end of the motor 801 is fixedly connected with a main bevel gear 802. A secondary bevel gear 803 meshing with the main bevel gear 802 is arranged on the main bevel gear 802, and a lead screw 804 is fixedly connected to the secondary bevel gear 803. The motor 801 is used to drive the main bevel gear 802 to rotate, and through the cooperation of the secondary bevel gear 803, the lead screw 804 rotates.

[0025] The working principle of the present utility model is as follows: First, when the lower die 7 is replaced, the arc surface of the fixing rod 11 is squeezed, and it will shrink into the base 6. Subsequently, through the cooperation of the auxiliary spring 12, the fixing rod 11 is inserted into the lower die 7, and the lower die 7 is limited by inserting the auxiliary positioning block 10 into the lower die 7. Then, the pull ring 502 is pulled, and with the assistance of the auxiliary wheel 506 and the main steel wire rope 504, the secondary steel wire rope 505 pulls the positioning rod 503 to disengage it from the insertion with the upper die 4. After the upper die 4 is replaced, the pull ring 502 is released, and through the cooperation of the elastic force of the connecting spring 507, the positioning rod 503 is inserted into the upper die 4 to fix the upper die 4.
