摘要:冷冲压加工在我国已有很长的历史，封建社会时期我国劳动人民纯手工打造金、银和铜饰品，制作各种日用品，就已显示出精巧的工艺技术，但那时人们劳动强度大，制作时间长，不宜生产大量的生活用品供生活所需，随着现今科技的进步，工业发展，模具在工业生产中引起了人们的重视。冲压模具生产产品效率高，能保证工件的精度，实现了自动化，适合大批量生产。未来模具将向全面推广CAD/CAE/CAM,模具优质材料及表面处理技术，特种加工，模具扫描及数字化系统，模具研磨抛光将自动化、智能化，模具自动加工系统方向发展。
本设计是对漏油器外壳的落料、拉深、冲孔级进模的设计，完成的内容为：对模具在工业生产中的作用，模具发展历史与现状，未来模具的发展前景做了概述。进行零件的形状、尺寸、精度工艺分析，确定合理的工艺方案，确定工序数目。确定毛坯尺寸，判断能否一次拉成，合理排样，绘制排样图，计算冲裁力、推件力、顶件力、卸料力、拉深力，确定压力中心。确定拉深凸、凹模间隙，计算落料、拉深、冲孔的凸、凹模刃口尺寸。确定凸、凹模结构，并绘制零件图，设计定位零件，压料、卸料、出件零部件，设计固定零件，选择模架标注紧固件。最后绘制模具非标准零件图，用CAD和UG分别画出二维与三维装配图，三维图并生成爆炸图。
本设计运用模具使钢料产生塑性变形，获得最终需要的零件，这是一种少切削、无切削、多工序重合的生产方法，并且利用级进模生产零件，提高了生产效率，对相似工件的大批量生产具有参考的作用。

Abstract:Cold stamping has a long history in China. The period of feudal society, our working people handmade gold, silver and copper jewelry, production of daily necessities, Already shows a sophisticated technology, But then the people to the labor intensity of production a long time, should not produce large amounts of daily necessities for living expenses. With today's advances in technology, industrial development, attracted the attention of people die in industrial production. Stamping mold products, high efficiency, to ensure the precision of the workpiece, automated, suitable for mass production. The mold will comprehensively promote the automation of CAD / CAE / CAM, mold-quality materials and surface treatment techniques, special machining, mold scanning and digitizing systems, mold grinding polishing, intelligent, mold automatic processing system direction.
This design is the oil spill shell blanking, deep drawing, Punching Progressive Die Design, Completed as follows : The role of mold in industrial production, mold development history and current situation, future prospects for the development of the mold to do an overview. The part shape, size, precision and process analysis , To determine a reasonable process , To determine the process number, To determine the blank size, to determine whether to pull into for a time, Reasonable layout, drawing layout diagram, Calculate the blanking force, pushing pieces of force, the top pieces of force, the discharge power, drawing force, determine the center of pressure. Make sure the convex drawing, the die gap to calculate the convexity of the blanking, deep drawing, punching, and the die edge size. Determine the convex and concave mold structure, and draw the parts diagram, locate the part of the design, binder, discharge, the piece parts, design of fixed parts, select mold label fasteners. Finally draw the mold non-standard parts diagram, draw 2D and 3D assembly drawings, three-dimensional map with CAD and UG, respectively, and generates the exploded diagram.
The use of design mold steel material of the plastic deformation, to obtain the final parts, this is a little cutting, cutting, multi-process production methods overlap, and progressive die production parts, improve production efficiency, similar to the workpiecehigh-volume production with reference to the role.
