When the drawing die 11 is installed in the groove of the die base 1, the first spring 16 drives the locking plate 14 on the outside of the shift block 12 to be inserted into the slot of the drawing die 11 through its own elastic force, thereby completing the preliminary assembly and fixation of the die base 1 and the drawing die 11. At the same time, the magnetic force of the magnetic block 15 can stably fix the locking plate 14 in the slot, thereby improving the assembly firmness of the die base 1 and the drawing die 11.

[0022] The inner side wall of the groove is evenly provided with mounting holes, and a second spring 17 is fixedly arranged in the mounting hole. The front side of the second spring 17 fits with the rear side of the drawing die 11. At this time, the second spring 17 is in a compressed state, and the elastic force of the second spring 17 applies a thrust to the drawing die 11, so that the locking plate 14 is tightly inserted into the slot of the drawing die 11, thereby further improving the assembly firmness of the die base 1 and the drawing die 11. When the drawing die 11 needs to be disassembled, the chamfered groove 21 can make it easier for workers It contacts the shift block 12, and the locking plate 14 can be separated from the slot of the drawing die 11 by pushing the shift block 12 outward. At the same time, the thrust applied to the drawing die 11 by the second spring 17 can drive the drawing die 11 to slide forward, thereby improving the convenience and speed of disassembly of the drawing die 11. A second guide groove is opened on the rear side of the slide groove 2, and a guide block 13 is fixedly arranged on the rear side of the shift block 12. The guide block 13 is slidably arranged in the second guide groove, and the guide block 13 assists the shift block 12 to move stably left and right.

[0023] Working principle: When the drawing die 11 is installed in the groove of the die base 1, the first spring 16 drives the locking plate 14 on the outside of the shift block 12 to be inserted into the slot of the drawing die 11 through its own elastic force, thereby completing the initial assembly and fixation of the die base 1 and the drawing die 11. At the same time, the locking plate 14 can be stably fixed in the slot through the magnetic force of the magnetic block 15, thereby improving the assembly firmness of the die base 1 and the drawing die 11. At this time, the second spring 17 is in a compressed state, and the elastic force of the second spring 17 applies a thrust to the drawing die 11. In this way, the locking plate 14 is tightly inserted into the slot of the drawing die 11, thereby further improving the assembly firmness of the die base 1 and the drawing die 11. When the drawing die 11 needs to be disassembled, the chamfered groove 21 can make it easier for workers to contact the shift block 12. By pushing the shift block 12 outward, the locking plate 14 can be separated from the slot of the drawing die 11. At the same time, the thrust applied by the second spring 17 to the drawing die 11 can drive the drawing die 11 to slide forward, thereby improving the convenience and speed of disassembling the drawing die 11.
