摘要
以某车型翼子板为例,从降低拉伸深度、优化补充面、分模线、拉伸筋形状及拼合方式方面,提出了提高翼子板材料利用率的方法,对拉伸冲压工艺进行优化。建立拉伸过程有限元模型,对比优化前后制件成形后的最小次应变分布、塑形应变、A面潜在缺陷及材料利用率,对于采用卷料方式计算优化后材料利用率由44.5%提升到69.1%。
Take a fender as example,give the methods to improve the material utilization rate of the fender from reducing the draw depth,optimizing addendum surface,punch open profile,the shape of draw bead and combination mode.Optimize the stamping process of drawing.Build the finite element model for the drawing process,compare the minimum strain distribution,plastic strain,potential cosmetic surface defect of A surface of the simulation-result and the material utilization rate of the part before and after optimization.For coil mode calculation,the material utilization rate is increased from 44.5%to 69.1%after optimization.
