端盖落料拉深模设计摘 要：本论文介绍了带凸缘件拉深的成形方法和条件及其拉深模的设计过程，拉深是利用拉深模在压力机的压力作用下，将平板预制金属坯料或空心工序件制成开口空心件而不产生过度起皱、变薄和拉裂的加工方法。它可以成行出带直边、斜边或两者混合或带弯曲边的圆柱形或盒形的制件。本文要设计的制件为带凸缘圆柱形件。拉深模结构较简单。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。本文要设计的模具为单动压力机复合工序压边装置拉深,内容主要包括模具结构设计、零部件的加工以及装配、应用CAD进行各重要零件的设计等。关键词：拉深；模具装配；模具结构Abstract：The paper introduces the methods， process and conditions of drawing with flange .Drawing is the process of changing a flat，precut blank into a hollow vessel without excessive wrinking，thinking，or fracturing . The various forms produced may be cylindrical or box shaped with straight or tapered or curved sides.The part introduced this paper is cylindrical and a part with flange.The structure of drawing dies is simple. According to the differend kinds of presss used by the dies，drawing dies can be divided into single action dies、double action dies. According to the differend methods of compositing of stations，drawing dies can be divided into single station，compound station dies and continous stations drawing dies. According to a die whether has pressure pad or not，drawing dies can be divided into dies with pressure pads and dies without pressure pads. The die introduced this paper is a single action，compound station die which has a pressure pad. The paper consists of the design of the drawing die structure，the manufacturer and assembling of the portion of the die，and the applacation of CAD in des
