Influence of Slide Stroke Curves on Forming Quality of Box Shaped Part during Deep Drawing

Abstract:

To explore the influence of slide stroke curves on deep drawing and solve the problems of cracking and wrinkling during drawing, the deep drawing processes of box shaped part with the conventional mechanical press and servo press were simulated, respectively. The variation rules of cracking and wrinkling for box shaped part by different slide stroke curves were obtained. It shows that the qualified parts can be obtained more easily when drawing with servo presses by decreasing the rotational speed of servo motor at the forming stage due to its variability; drawing cycle can be shorten effectively by adjusting the variable displacement-velocity curves of servo press.
