摘　　要：根据接触簧片的结构特点,采用级进模冲压生产,介绍了制件排样设计、模具结构设计及模具关键零件设计。模具采用侧刃初定位、导正销精定位及2种浮料装置,保证了送料精度,同时采用完全镶拼式结构,可根据试模情况及时调整成形部位尺寸。模具现已投入生产,实践表明,模具结构合理、可靠,制件质量符合图纸要求,可为同类制件的级进模设计提供参考。A progressive die for stamping a contact spring was developed according to its structure characteristics. The part layout, the design of die structure and key components were described in detail. The feeding precision was guaranteed through initial positioning by side edge, accurate positioning by pilot pin and two types of floating material device. The insert structure can simplify the replacement of forming parts.
