Influence of Slide Stroke Curves on Deep Drawing of Box Shaped Part

摘要：

In order to explore the influence of slide stroke curves on drawing process and solve the problems of springback and serious thickness thinning during forming, the deep drawing processes of box shaped part based on the conventional mechanical press and servo press were simulated. The springback and thickness variation of box shaped part by different slide stroke curves were obtained. It shows that comparing with the deep drawing with conventional mechanical press, the springback of drawn workpiece decreases by pressure-keeping drawing;the maximum thickness thinning ratio of drawn workpiece is smaller by staged drawing, and the distribution of workpiece thickness is more uniform.
