摘要：

以某汽车座椅侧板为例，采用有限元分析软件AutoForm对座椅侧板拉延和翻边成形进行模拟分析，为解决其翻边成形过程中回弹量过大的问题，在翻边成形过程中增加挡板进行预成形，成功解决该问题。为得到更好的成形效果，设计4因素3水平正交试验，选取压边力、模具间隙、冲压速度和摩擦系数作为因素。试验结果表明：回弹量随冲压速度和模具间隙的增大而变大，摩擦系数和压边力对回弹量影响较小。综合考虑后得出最优参数组合为：压边力为250 kN，板料间隙为1.05t，冲压速度为10 mm·s-1，摩擦系数为0.16。采用最优参数组合进行试模，制件成形质量良好，与模拟结果一致，为制件实际生产提供了理论依据。

For the seat side blank of an automobile, its deep drawing and flanging processes were simulated and analyzed by finite element analysis software AutoForm. In order to solve the excessive springback during flanging process, the pre-forming was designed by adding a baffle in the flanging process, and the above problem was solved successfully. Furthermore, the orthogonal experiment of four factors and three levels was designed to get a better formability, and the blank holder force, die clearance, stamping speed and friction coefficient were chosen as process parameters. The experimental results show that the springback increases with the increasing of stamping speed and die clearance, while friction coefficient and blank holder force have little effect on the springback. After comprehensive consideration, the optimal parameter combination is obtained with the blank holder force of 250 kN, die clearance of 1.05t, stamping speed of 10 mm·s-1 and friction coefficient of 0.16. Thus, the high-quality part is obtained by the optimum parameters, and the experiment results are consistent with the simulation results to provide a theoretical basis for the actual production of parts.
