摘　　要：覆盖件等复杂形状零件成形时，主要通过压料面对毛坯变形实现正确的控制。因此，压料面形式的选取对覆盖件成形至关重要。本文实验研究了柱面压料面对矩形盒件拉深变形的影响，得到了柱面压料面形式对成形极限及毛坯变形区应变分布的影响规律。In forming large complicated coveringparts,blank is mainly controlled by blankhold surface. Blankhold surface is vital to coveringparts forming. In this paper,expriments are done to study the effct of cylinder blankhold surface on rectangle box part drawing,and the effect law of between cyllinder surface and forming limits,strain distribution in deformation area are proposed.
