Description

Technical Field

[0001] The utility model relates to the technical field of metal parts, in particular to a metal part stamping jig. Background Art

[0002] When metal parts are produced and processed, they usually need to be stamped to facilitate the processing and forming of the metal parts.

[0003] A Chinese patent with application publication number CN212494750U discloses a metal parts stamping jig. In the patent, the core body and the pressure head with overlapping vertical central axes are connected naturally, and the force directions of the two are consistent, which increases the firmness of the installation and stabilizes the force, which is conducive to long-term installation and use. The screw and the pressure head of the threaded connection are tightly connected, and the installation is natural, which also facilitates the disassembly of the two from each other. The pressure head will be damaged during long-term high-intensity stamping, but the two can be directly separated by the threaded connection between the screw and the pressure head, which is convenient for repair and replacement of the pressure head.

[0004] When using the above patent, we found that the device does not have the ability to fix metal parts, and it is easy to cause the metal parts to move during the stamping process, making it inconvenient to stamp the metal parts. Therefore, we proposed a metal part stamping jig. Summary of the invention
