根据前面的受力分析和模拟结果，利用激光对凸模圆角区进行了毛化处理；
According to the previous mechanical analysis and simulation results, using laser punch fillet area of texture processing;
结果表明，凸模和凹模交界处的板料首先变形，应力及应变最大值出现在凸模圆角部位外侧板料上。
The results show that the sheet in the adjacent area of die and punch deforms primarily. The maximal value of stress and strain appears in the sheet of outboard punch round corners.
研究表明不同可控拉深筋路径对盒形件侧壁和凹模圆角部位的应变路径影响不大，而对凸模圆角处的影响较为显著。
The results show that the different CD moving paths have little effect on the strain paths of box sidewall and die corner, which have significant effect on punch corner.
