Disappearance, product just has restorable trend after demoulding, cannot comply fully with expected mold shape, influence product accuracy.
According to rebound producing cause-elastic deformation, it can be deduced that rebound can not be eliminated itself, can only take from engineering viewpoint certain
Control measure.Since rebound cannot be completely eliminated in itself, certain means can only be taken to be controlled, so there are two types of angles at present
Control rebound: (1) from material stamping parts is overcome to spring back.The heat treatment for carrying out certain way before punching press to material, improves stress
Situation, can decreasing rebound to a certain degree.(2) bool is overcome to spring back from mould structure.If choosing first way, that
Some unnecessary processes will be will increase, increase process costs.More economic mode is by improving mould structure, drop
Low original springback capacity.However existing mold is mostly rigid die, i.e., requires to make specific mold for a kind of rebound part,
This method higher cost, production mold process is also excessively complicated, and the part production cycle is long, therefore, studies a kind of unitized
It is just very great for the meaning of the apparatus for correcting of the rebound part of different shape size.
