摘要
探讨了带凸台零件用模冲的设计。指出该模冲设计的关键问题是模冲凹槽的自锁角和形状问题。本文推导出自锁角公式ｔｇα＝Ｂ，并给出铁铜基两种材料的压坯、整形坯和浸油后的整形坯的静摩擦系数。
Design of the punch with cavity is discussed.It is indicated that the key to the degign lies in self blocking angle and shape of the cavity.It affords facilities for the design of the cavity that self blocking angle formula,tgα=B,has been derived and the static friction factors of compacts,sizing compacts and oil impregnated sizing compacts for Fe and Cu base materials are given.
