Abstract:

The stamping process is mainly used in the automotive industry to manufacture parts. However, there is a major problem with the geometrical variations of the part which lead to assembly difficulties, this problem is known as the spring back, that is to say the propensity of the sheet to recover its original shape after being deformed, this results in a geometric variation of the part which affects the final assembly. ; In this article, we started by modelling the drawbead force and then examined the consequences of drawbead on the spring back, which is one of the essential elements of the stamping process. We have demonstrated that the type of drawbead chosen plays a crucial role in the spring back of the part. We have therefore carried out a comparative study between two types of drawbead, the bead and the step bead. The result shows that the use of a step bead as a type of drawbead improves spring back.
