In order to achieve flexible pressing and be suitable for pressing different stamped parts, a buffer cavity is provided in the pressure block 8, and a pressing rod 11 slides in the buffer cavity. A support spring 12 is also provided on the top wall of the buffer cavity, and the bottom of the support spring 12 is connected to the top of the pressing rod 11. Multiple sets of support springs 12 and pressing rods 11 are evenly distributed. The bottom of the pressing rod 11 is provided with an anti-slip rubber sleeve 19 to avoid scratching the surface of the stamped parts. To facilitate the inspection, maintenance and replacement of the positioning frame 4 and the positioning components 5 thereon, a positioning plate 20 is also included. The four corners of the positioning plate 20 are provided with locking screws 21. The positioning frame 4 and the driving component 3 are provided with screw holes corresponding to the locking screws 21 on their respective sides. At the same time, the positioning frame 4 and the driving component 3 are positioned by pins and pin holes on their connecting surfaces.

[0027] The push-pull column 13 is equipped with an anti-slip sleeve for easy manual pushing and pulling.

[0028] Example 2

[0029] Based on Example 1, such as Figure 3 As shown, in order to flexibly adjust and fix the slide block 6, a push-pull column 13 is provided on one side of the slide block 6 and extends to the outside of the positioning frame 4. A friction block 14 and a threaded locking nut 15 are also slidable on the push-pull column 13. In use, the friction block 14 is pressed against the side wall of the positioning frame 4, and the positioning of the slide block 6 is achieved by the locking nut 15 pressing the friction block 14.
