Background technique

In the forging industry, for forgings with complex shapes, the optimization of the process can change from complex to simple or simpler. Forging locks are one of the more complex forgings.

In order to reduce the difficulty of forging the lock bolt, the original forging process "cutting - heating - billet - forming - trimming - grinding - shot peening - sending out" was improved and changed to "cutting --heating--blank-forming-cutting-edge-twisting-grinding-shot-peening-issue".

Compared with the original forging process, a torsion step is added. The torsion is a forging process in which one part of the forging is rotated at a certain angle relative to the other part around its axis. Usually, one end is fixed and the other end is pressed by a press to achieve deformation, but this method is not easy to control the amount of torsional deformation, and it can only be twisted in one direction.
