内容简介：

端罩的冲压成形工艺及冲压模具设计摘要：本设计题目为端罩的设计，体现了深薄壁类零件的设计要求、内容及方向，有一定的设计意义。通过对该零件模具的设计，进一步加强了设计者冷冲模设计的基础知识，为设计更复杂的冷冲模具做好了铺垫和吸取了更深刻的经验。本设计运用薄板类零件成型工艺及模具设计的基础知识，首先分析了零件的成分及性能要求，为设计拉深及冲裁模的数据指标做好了准备；然后计算了零件的体积，便于设计落料模的刃口尺寸；最后设计了模具的结构特征，确定了模具的设计参数、设计要点及推出装置的设计。冲压加工分为分离工序和成形工序两大类。落料、打孔属于分离工序，拉深属于成形工序。设计任务是指导老师指定加工的零件为有孔拉深件，材料为铝L3，厚度为2mm，大批量生产，其他具体要求参照零件图。根据零件形状，需要采用落料、拉深、冲孔3个工序，为提高成倍提高生产效率，提高冲压件的质量，可采用落料和拉深过程集中于一套模具来完成，冲孔工序用简单模完成。关键词：落料 拉深 冲孔 The drop-cylinder-shaped pieces of material, drawing, punching, trimming the compound die designAbstract：The design of the sets of topics for the long injection mold design, reflects the deep thin wall plastic parts of the design, content and direction of a certain design significance. Parts of the mold through the design, the designer has been further strengthened by the injection mold design based on knowledge, for the design of more complex injection molds made and lessons foreshadowing a more profound experience The use of thin design parts molding process and die design of the basic knowledge, first of all parts of the composition and performance requirements for the design and drawing Die data prepared for the target and then calculate the size of the parts, for design Blanking the edge-size; final design of the structure of the mold, a mold determine the design parameters, design elements and the introduction of the device design.Cutting and piercing belong to separating , pulling and stretching belong to calendering. The spare parts fall to cut material-pull and stretch compound die and multiple hole punched die to process.The job is in order to process the multiple hole punched die and pull-stretch die design which is given by the tutor , the material is AL L3 , the thickness is a 2 mm, the large quantity quantity produce, other request to according to the spare parts diagram in a specific way. According to the spare parts shape,it need to to cut material,to pull and stretch,to punched hole 3 work, become for the exaltation to raise the production efficiency doubly, raise to the quantity of part, to cut material and to pull and stretch adopt to compound die t
