Abstract

Thinning is one of the main reasons that caused parts scrap, the geometry size is not accurate and the finished part has a poor quality in the process of cold stamping. Based on the orthogonal experiment method, LS-DYNA software is used in this paper to carry on the deep drawing process of box parts with finite element simulation. The thickness of the thinnest place is selected to indicate the quality of the finished parts and the main effect of technical parameters of deep drawing process which makes the variation in thickness of the thinnest place of box parts. The analysis shows that the most important factor which affects the thickness of the minimum is blank holder force, the second is the concave die entrance radius, the influence of Punch velocity and the radius is minimal. Thus the optimal process parameters of blank-holder force is 200 KN, die entrance radius is 4 mm, combined with punch radius 5mm, punch velocity 2000 mm/s.
