冲裁是利用模具使板料沿着一定的轮廓形状产生分离的一种冲压工序.它包括落料、冲孔、切断、修边等工序,其中落料和冲孔是最常见的二种工序.它是冲压工艺的最基本工序之一.在冲压加工中应用极广.它既可直接冲出成品零件也可以为弯曲、拉深和挤压等其它工序准备坯料,还可以在已成形的工件进行再加工（切边、冲孔等工序）.本文介绍了带法兰圆筒拉深复合模的设计,通过对工件的工艺分析,确定了最终的工艺方案：①落料——首次拉深成形 ②继续用第一套模具二次拉深 ③换套磨具进行冲孔切边.主要介绍了落料——拉深,冲孔——切边两套复合模具的主要工作部分尺寸设计及计算和磨具结构的设计.并绘制了两套模具的装配图和主要的零件图.

Blanking is the use of sheet metal along the mold so that the outline must have a separation of the shape of a stamping process.It includes blanking,punching,cutting,trimming processes,including blanking and punching is the most common of the two kinds of processes.It is the stamping process,one of the most basic processes.Stamping processing in a wide range of applications.It can also direct out finished parts for bending,deep drawing and extrusion billet preparation,and other processes can also be formed in the workpiece has been re-processing (trimming,punching and other processes).In this paper,drawing with cylindrical flange compound die design,through the process of analysis of the workpiece,the process to determine the final program:① blanking - the first deep drawing ② continue to use the first set of the second drawing die ③ sets for edge grinding apparatus for punching.Introduced blanking - deep drawing,punching - Trimming the two sets of composite die size of the main part of the design work and calculations and the design of abrasive structure.And mapping the two sets of mold assembly and the main parts of the map.
Keywords:Blanking; Drawing; compound die; flange cylinder
