内容提要
本论文应用本专业所学课程的理论和生产实际知识进行一次冷冲压模具设计工作的实际训练从而培养和提高学生独立工作能力，巩固与扩充了冷冲压模具设计等课程所学的内容，掌握冷冲压模具设计的方法和步骤，掌握冷冲压模具设计的基本的模具技能懂得了怎样分析零件的工艺性，怎样确定工艺方案，了解了模具的基本结构，提高了计算能力，绘图能力，熟悉了规范和标准，同时各科相关的课程都有了全面的复习，独立思考的能力也有了提高。。采用落料拉伸复合模，能较好地实现落料及落料件的修边，模具设计制造简便易行。落料拉伸效果好，能极大地提高生产效率，但落料拉伸凹模设计较为重要，设计中应充分考虑其落料拉伸模口形状，否则易影响落料拉伸件的形状。主要工序包括：a复合下料，冲孔，b全周压毛边，冲孔，小折，c冲孔，铆螺母，d成型。本设计共分6章，分别论述了产品工艺分析，冲压方案的确定，工艺计算，模板及零件设计，模具组立等问题。本论文是第三工程（冲孔）的模具。本设计的内容是确定复合模内型和结构形式以及工艺性，绘制模具总图和非标准件零件图。
Content summary
Thus the present paper applies this specialty to study the curriculum the theory and the production know-how carries on a time cold stamping mold design work the actual training to raise and to sharpen the student independent working ability, consolidated and expanded the content which curricula and so on cold stamping mold design studied, the method and the step which the grasping cold stamping mold designed, the basic mold skill which the grasping cold stamping mold designed had understood how analyzed the components the technology capability, how definite craft plan, had understood the mold basic structure, sharpened the computation ability, cartography ability, has been familiar with the standard and the standard, simultaneously various branches correlation curriculum all had the comprehensive review, independent thinking ability also had the enhancement. . can enhance the production efficiency enormously, but falls the material to stretch the concave mold design to be important, in the design should consider fully it falls the material stretch mold mouth shape, otherwise easy to affect falls the material stretches the shape. the punch holes, small booklet, c punch holes, riveting nut, d formation. This design altogether is divided 6 chapters, elaborated the product craft analysis separately, the ramming plan determination, the process design, the template and the components design, the mold group at once question. The present paper is the third project (punch holes) mold. This design content is determined the superposable die former and the structural style as well as the technology capability, draw up the mold assembly drawing and the non-standard letter detail drawing.
