Abstract：

Because the minimum thickness or the maximum thickness could reflect the cracking or wrinkling trend of material after the roof cover plate stamping, the influences of different factors such as blank holder force, stamping speed, friction coefficient, die clearance and drawbead width on thickness were studied by a combination of orthogonal experiment with AutoForm stamping simulation software under the single factor experiment and orthogonal experiment, and the thickness variation was set as evaluation index. Then, the primary and secondary sequence of various factors and the significance influence of different factors on thickness were determined by range and variance analysis, and the optimal stamping process parameters were confirmed. Finally, the physical model was verified by the actual production. The results show that the thickness variation decreases with the increase of various factor values. Therefore, the sequence of influence on the minimum thickness and the selection values are stamping speed of 1500 mm·s-1, friction coefficient of 0.15, die clearance of 0.63 mm, drawbead width of 18 mm and blank holder force of 200 kN.
