摘要

模具是现代工业生产中重要的工艺装备之一。在铸造、锻造、冲压、塑料、橡胶、玻璃、粉末冶金、陶瓷等生产行业中得到广泛应用。近年来，我国的模具工业也有了较大的发展，模具制造工艺和生产装备智能化程度越来越高，极大地提高了模具制造的精度、质量和生产率。

本设计是垫片的冷冲压模具设计，利用的是级进模生产的。级进模，又称为多工位级进模、连续模、跳步模，它是在一副模具，按所加工的工作分为若干等距离的工位，在每个工位设置一个或几个基本冲压工序，来完成冲压工作某部分的加工。被加工材料，事先加工成一定宽度的条料，采用某种送进方法，每次送进一个步距。经逐个工位冲制后，便得到一个完整的冲压工件。在一副级进模中，可以连续完成冲裁、弯曲、拉深、成形等工序。一般来说，无论冲压零件形状怎么复杂，冲压工序怎样多，均可用一副级进模冲成完成。

本设计重点是在分析冲裁变形过程及冲裁件质量影响因素的基础上，主要介绍冲裁件的工艺性分析、确定冲裁工艺方案、选择模具的结构形式、进行必要的工艺计算、选择与确定模具的主要零部件的结构与尺寸、校核模具闭合高度及压力机有关参数、绘制模具总装图及零件图都是这次设计的主要容。

本次设计不仅让我熟悉了课本所学的知识，而且我做了把所学到的知识运用到实践当中，更让我了解了级进模设计的全过程和加工实践的各种要点。

The pad stamps forming handicraft and design for die

Abstract:The mod is one of the most important Technology and Equipment in modern industry.It’s been widely used in casting ,forging,stamping plastic, rubber, glass, powder metallurgy,

ceramics etc.In recent years,die industry gets larger development.die manufacturing process and the more intelligent level of production equipment improve the accuracy ,quality and productivity greatly.

The graduation project is progressive die design.In a pair of mod, according to the process of the work is divided into a number of equal distance to the station, set up the basic stamping one or several steps in each station, to complete the processing of a part of the stamping work..Materials to be processed, previously processed into strip width, a feeding method, each in one step.Each station by punching, stamping workpiece will be a complete.In a progressive die, blanking, bending can be continuously completed, drawing, forming process. In general, no matter how complex shape stamping parts and stamping process are, it’s can make by a progressive die .

This design focus on the analysis of blanking deformation process and impact factors based on quality of blanking pieces,main introduction and analysis of the blanking process,determining the plan of stamping process,selection of die structure,calculation the necessary process, selection and determination the structure and size of the main components of the mod,checking the mold height and press parameters,drawing die assembly drawings and part drawings are the main content of this design.

This design not only let me know the textbook knowledge, put the

knowledge into practice, but also let me understand the various points of the whole process and processing practice of progressive die design.

Key words:Piecening progressive die cold stamping
