摘 要：盒形件拉深主要变形区集中在盒形件角部的法兰和凹模圆角部位。根据盒形件拉深的特点，假设盒形件圆角区剪应力零线与圆筒形拉深件的变形规律相同，通过理论推导得到了盒形件角部变形区法兰和凹模圆角处的应力解析表达式，为定量研究盒形件拉深成形提供了理论依据。

Abstract: The main deformation areas of the rectangular box in deep drawing were flanges and the circlecorners of female die in the corners. With the deformation characteristics of rectangular box in deep drawing, analytical solution of stress on deformation area had been obtained on the basis of the hypothesis that deformation law of shear stress zeroline was the same as the corresponding axisymmetric work pieces, a theoretical basis for qualitative analysis of deep drawing for rectangular box was provided.
Key words: rectangular box; deep drawing; analytical solution of stress
