Abstract:

The current work deals with numerical simulation connected to forming of a rectangular shaped part made from tailored blanks (TWB’s), having the welding line positioned symmetrical with respect to the part geometry. During the deep drawing process, due to dissimilar base materials of the TWB’s, the welding connection modifies its initial position. The presented work is trying to demonstrate the important role of the blankholder force on the welding line movement during the deep drawing process. To simulate the forming process the academically version of the PAM STAM 2G software have been used. After each simulation the obtained part is analysed and measured to quantify the movement of the welding line.

Keywords:
