[0003] Moreover, in the application document with the publication number of CN219324704U, a bending die for automobile parts is mentioned. This die opens the protection window through a handle, then places the automobile part in the wear-resistant layer at the upper end of the V-shaped table, then closes the protection window, fixes the protection window through a fixing block, then opens the hydraulic telescopic rod, and bends the automobile part through the stamping die. The shock-absorbing pad at the lower end will offset the impact force of the stamping die to a certain extent, but there are still certain defects that need to be optimized. The specific defects are as follows: the upper die stamping head of this die will also wear after long-term use, and at the same time, the parts are not positioned during the stamping process, and the parts are prone to displacement.

[0004] Therefore, it is particularly important to design a bending die for automobile parts to change the above technical defects and improve the overall practicability. Content of the Utility Model
