| 摘 要： | 在薄板矩形盒拉深试验的基础上,进行压料面带拉延槛拉深的有限元模拟分析后指出,在压料面直边部设置相应的拉延槛,增大法兰直边的进料阻力并控制直边流入速度,可相应提高拉深成形极限。设置拉延槛后,使直边轴向拉深变形量增加,整体塑性变形充分,因而相对减轻法兰起皱趋势,并提高矩形盒的整体刚度和成形性。

| Abstract: | Based on the sheet metal rectangular case drawing experiments,have conducted the finite element analysis and simulation on the rectangular case forming with draw step.It has been pointed out that increasing the straight edge's blank feeding resistance and controlling its feed speed after placing draw step on the straight flange can increase the rectangular case's forming limit.The draw step can increase the axial deformation of the straight edge and make the plasticity forming become more sufficient,therefore relatively lightens the crinkle trend and heightens the rectangular case's rigidity and formability. |
