2、具的冲孔、弯曲、切断凸模用同一固定板固定;冲孔凹模和切断凹模采用整体固定板固定。落料、切断凸模间装有导正销,保证了工件上孔和外形的相对位置准确,提高了加工精度。如此设计出的结构可确保模具工作运行可靠和冲压产品大批量生产的要求。关键词:连续模;冲压模具;标准模架;冲压设备;校核;冲孔;落料;弯曲;IABSTRACTThisdesigncarriesonblanking,thepiercingprogressivediesdesign.Thearticlehasbrieflyoutlinedthepressdieatpresentdevelopmentconditionandthetende
