摘　　要：在拉深成形过程中,摩擦系数在一定程度上影响着拉深的深度。文中对两者之间的关系进行了理论分析,并通过有限元的方法进行模拟验证,发现在一定程度上,减小摩擦系数有利于拉深深度的增加。在此基础之上,文中提出了一种新的滚珠压边圈模型,大大减少了材料间的摩擦系数,提高了材料的拉深深度极限。In deep drawing process, friction coefficient has some influences on the drawing depth. This article makes a theoretical analysis about the relationship between them, and verify them through the finite element method. Founding in a certain extent, reducing friction coefficient can increase the drawing depth. On this basis, this paper presents a new ball blank-holder model, which can greatly reduce the friction coefficient between material, and can improve the material of deep drawing depth limit.
