Preferably, the two sunken platform holes are internally provided with inner step holes with threads, and two ends of the spring are respectively connected with the fixed part and the movable part through the threads. The spring is prevented from falling off in the machining process by arranging the threads and connecting the spring.

The utility model has the advantages that the original male die is divided into two parts, the fixed part and the movable part can slide relatively, the male die with the negative angle part is formed by combining the two parts together during stamping, the section width can be reduced in the return stroke process of the movable part under the action of spring reset after stamping, when the sum of the width and the width of the fixed part on the same horizontal plane is less than the minimum width of the part, the male die can be withdrawn from the part with the negative angle from the positive direction, and the stamping part is suitable for stamping the part of the part type with the negative angle part needing to be rotated during stamping; the process of preventing the parts from being clamped in the die and rotating the parts is omitted, so that continuous production can be realized, the production efficiency is improved, and the cost is saved. The process of preventing the parts from being clamped in the die and rotating the parts is omitted, so that continuous production can be realized, the production efficiency is improved, and the cost is saved. Meanwhile, due to the simple structure, a large number of standard parts can be used, the processing difficulty is reduced, the preparation of a bench worker is simplified, and the production cost is further saved.
