PAGE 毕业设计（论文）题目名称：汽车点火器金属件（2）冲压工艺工艺与模具设计The metal parts of auto Igniters (2)Stamping process and die designing院系名称： 材料与化工学院班 级： 材控102学 号： 学生姓名： 指导教师： 2014年 6 月PAGE 摘 要本设计为一汽车点火器的冷冲压模具设计。根据所要设计零件的尺寸、材料、批量等要求，可分为以下步骤：首先分析零件的工艺性，确定拉深工艺方案及模具结构方案。然后通过一定的相关工艺设计计算，确定其工作尺寸、计算冲压力、间隙、初选压力机、计算凸、凹模刃口尺寸和公差。最后设计选用零、部件、绘制模具总装草图，以及对模具主要零件的加工工艺规程进行编制。在结构设计过程中，主要对凸模、凹模、压料圈、上模座、下模座、冲压设备、固定板等进行了设计，对于部分零部件，因为所选用的是标准件，就没深入设计。并且在结构设计的同时，对部分零部件进行了加工工艺分析，最终才完成这篇毕业设计论文。关键词：模具；拉深；凸模；凹模；凸凹模AbstractThe design for the Auto Igniters of a drawing of cold stamping die design, according to the size of the design components, materials, mass production, and so on. We can do it just like this step : the first part of the process of analysis to determine the drawing process and the die structure of the program, and then through the process design calculations, to determine the size and the stamping pressure, and also the clearance , primary presses, computing convex and concave Die Cutting Edge dimensions and tolerances. The final design selection of parts and components, drawing die assembly drawings, as well as Mold processing technology of the main parts to the preparation procedures. In which the structural design, primarily to the punch and die, a ring of pressure, the upper die seat, a die holder, stamping equipment, mold, pressing equipment, fixed plate, etc. has been designed, for the selection of some components are standard parts, there is no in-depth design, and structural design, while some parts for the processing process analysis and ultimately to complete this graduation project.
