摘要 洛阳理工学院毕业设计（论文） PAGE XVII PAGE 7 微型电机机壳冲压模具设计 摘 要 本次课程设计的内容为无凸缘圆筒形件的模具设计，其中包括落料、一次拉深、二次拉深、冲孔、切边五道工序。其中把落料、首次拉深用复合模完成，二次拉深、冲孔、切边也使用复合模完成其成形工艺。因此，此次设计需要完成两套复合模设计，重点放在复合模设计上，主要包括落料拉深复合模和拉深冲孔切边复合模的模具类型的选择；重要零部件如凸凹模、凸模、凹模的形状设计和尺寸计算；模具零件的间隙配合的选取；模具结构初步设计和总装草图绘制；模具总装图绘制和部分零件图的绘制；最后认真完成开题报告、相关外文期刊的翻译以及毕业设计说明书的编写。 关键词：无凸缘圆筒形件，落料，拉深，冲孔，切边 WICRO-MOTOR CHASSIS STAMPING DIE DESIGN ABSTRACT The content of this course design for no of flange cylindrical parts mold design, including blanking，The first deep drawing ，secondary deep drawing ，punching and trimming five working procedure drawing. Among them the blanking, the first deep drawing with composite die completed, second deep drawing, punching and trimming also use compound die to complete its forming process. Therefore, the need to design two sets of compound die is designed, emphasis on composite mold design, Mainly solve the blanking deep drawing composite modulus and deep drawing punching trimming compound die mold type choice, important parts such as convex concave die, punch, concave die shape design and the size calculation; The selection of mold parts clearance fit; Mold structure preliminary design and final assembly sketch rendering; Mold assembly drawing and parts drawing mapping; Finally seriously complete the opening report, related the translation of foreign periodicals as well as the writing of the graduation design instruction.
