带有浮动凸凹模的拉伸冲孔复合模设计

Design of Drawing and Piercing Compound Die with Floating Punch Block

为了保证零件的尺寸精度和位置精度要求 ,使拉伸系数较小的拉伸件能在普通的冲床上进行拉伸成形 ,介绍了1副具有浮动拉伸凸模、浮动冲孔凹模 ,方便调节压边力的模具 。

In order to meet the requirement of design for dimension and position precision,and to draw parts with small drawing coefficient on general stamping machine,a die with floating drawing punch and floating piercing matrix,and with easy-adjustable blank-holding force was introduced.This offered an effective forming way for similar parts.
