摘　　要：以接触簧片的冲压工艺设计为研究对象,运用弯曲件的工序安排方法和级进模的排样设计方法,主要研究了接触簧片的弯曲和切废工艺设计方案。结果表明:根据冲件结构特点,采用分段弯曲和分段切除余料的方法,交替安排弯曲工位、切废工位和空工位,可以优化模具结构;用有去屑功能的抬起块抬起条料,用限位块控制模具的冲压高度,用带弹压装置的导板和弯曲凸模压料,有效控制了偏移和回弹,保证了接触簧片的精度。Taking the contact spring’s stamping process design as an object of study,according to the process arrangement method of bending part and the layout design method of progressive die,the contact spring’s process design in bending and cutting waste was studied.The results show that based on the stamping structure characteristics,using the method of sectional bending and segmental resection of surplus material,arranging alternately bending station,cutting waste station and space station,the die structure can be optimized.Using the lifting block with removing chips function to lift strip,the limiting block to control stamping height of the mould,the guide board with elastic press device and the bending punch to press strip,the offset and the rebound are controlled effectively.The precision of contact spring is guaranteed.
