带凸缘筒形件-锥形件落料拉深工艺及模具设计【落料拉深复合冲压】 摘要：本介绍了拉深的成形方法和条件，拉深是利用拉深模在压力机的压力作用下，将平板坯料或空心工序件制成开口空心件的加工方法。旋转体拉深时的应力应变分析，还有拉深过程中的起皱和拉裂。拉深件毛坯的尺寸计算，和工艺计算，以及拉深次数的计算。拉深模结构相对较简单。根据拉深模使用的压力机类型不同，拉深模可分为单动压力机用拉深模和双动压力机拉深模；根据拉深顺序分为首次拉深和以后各次拉深；根据工序组合可分为单工序拉深、复合工序拉深和连续工序拉深；根据压料情况可分为有压边装置和无压边装置拉深。从模具设计到零部件的加工工艺以及装配工艺等进行详细的阐述，并应用CAD进行各重要零件的设计。 关键词：工艺分析；拉深成型；模具装配；模具结构 Abstract： The paper i
