Abstract :
The springback is mainly an elastic deformation which occurs after sheet metal forming processes. This paper analyzed the mechanism of deep drawing springback of sheet metal forming, and the springback compensation was studied. Based on this, taking the stiffener parts of auto as an example, the paper analyzed the trend and distribution of springback and its distribution under different conditions after the forming, and compensation was adopted with a multi-step implicit algorithm. The results showed that springback compensation was valid and the precision forming was realized.
