基于CAD/CAM/CAPP的圆形垫圈复合模具设计与制造工艺摘要：本课题研究圆形垫圈复合模具设计与工艺制造，经分析过后采用倒装式复合模，这种模具生产率高，工件精度高，但模具制造较复杂，调整维修较麻烦，使用寿命低。本次设计是利用计算机辅助设计(CAD)及UG绘制模具主要工作零件图和模具的总装配图，运用了数控切削加工、数控线切割电加工等先进加工技术。在这次设计中根据所给题目的要求，首先对冲压件进行了分析，分析该零件的尺寸精度得出用一般精度的模具即可满足零件精度的要求，再从零件的形状、尺寸标注及生产批量等情况看，选择加工方案。然后用UG或者CAXA做出仿真，直观的展现出模具的工作过程。其次希望能够灵活运用所学的专业知识和技能，圆满完成此次的设计。关键词：冲压；模具；复合模；工艺；仿真全套图纸，三维仿真，加The CAD/CAM/CAPP Of Circular Gasket Stamping Mould Design And Manufacturing ProcessAbstract: In the present the fierce competition in the market, products put on the market sooner or later is often key to success. In the graduation design using a computer aided design (CAD) drawing mould main parts of the die assembly drawings always chart and, using a numerical control machining, numerical control line electric processing advanced processing technology. In this design according to the requirements of the topic, first of stamping, based on an analysis of the part of that size precision with general precision of the mould can meet the accuracy requirement of the parts, and again from the shape of the parts, dimensions and production batch, etc, we can see the processing scheme selection. Based on the comprehensive analysis of the parts, in the design of the mould is I design inversion blanking punching composite die, are mainly introduced in this paper cutting technology, use UG or CAXA die structure and design, punch die blanking punching principle of work, etc. Hope to flexible using of major knowledge and skills, the successful completion of the design.Key words: Stamping, mould, separation process, process, simulation目录第1章 绪论11.1 模具行业的发展现状及市场前景11.2 设计目的及意义21.3 设计任务3第2章 冲裁件的工艺分析42.1 冲裁工艺的概念42.2 冲裁件的工艺性42.3 排样及材料利用率52.3.1 排样52.3.2 搭边52.3.3 条料宽度52.3.4 材料利用率52.4 方案的确定5第3章 冲压力及压力中心的计算73.1 冲裁力73.1.1 冲孔冲裁力P孔73.1.2 落料冲裁力P落73.2 卸料力P卸73.3 推料力P推83.4 顶件力P顶83.5 总冲压力P总83.6 计算模具压力中心8第4章 凹模凸凹模刃口及结构尺寸计算94.1 计算模具刃口尺寸94.1.1 落料刃口尺寸计算94.1.2 冲孔刃口尺寸计算94.2 结构尺寸计算94.2.1 落料凹模结构尺寸计算94.2.2 冲孔凸模结构尺寸确定104.2.3 凸凹模结构尺寸计算14第5章 模具总体结构设计155.1 模架155.2
