摘 要

本设计是对给定的产品图进行冲压模具设计。冲压工序的选择是经查阅相关资料和对产品形状仔细分析的基础上进行的;冲压模具的选择是在综合考虑了经济性、零件的冲压工艺性以及复杂程度等诸多因素的基础上进行的;产品毛坯展开尺寸的计算是在方便计算但不影响模具成型的前提下简化为所熟悉的模型进行的。文中还对冲压模具成型零件和其他相关零件的选择原则及选择方法进行了说明。冲压件的设计首先要从冲压生产工艺上对所要设计的铁芯片进行冲压工艺的分析与计算,然后在分析计算的基础上并参看相关的冲压设计资料确定冲压工艺方案,再在此基础上确定各工序的复合关系后,再进入冲模各具体结构的设计。在此基础上对各副冲压模具的主要零部件的尺寸进行设计与计算,期间要参考大量与冲压相关的资料和翻阅各种“冲压手册”,并通过计算以确定各副模具具体的结构及尺寸,通过不断的计算与修改,并在指导老师的悉心关怀和耐心指导下进行不间断的反复修改,最终确定画出了一副装配图和3副零件图和一张立体图。通过这次毕业设计使我了解和掌握了许多实际的东西,结合我在生产实习中所看所想的一些东西,有了自己的一些收获。在此特别感谢学院,学校各位老师给我的这次机会和悉心指导。

Abstract

The design of a given product plans for stamping die design. Stamping process is the choice of the available relevant information and a detailed analysis of the shape of the products on the basis of; stamping die option is considered in the economy, parts of the stamping process and the complexity of many factors, and so on the basis of; Products rough start calculating the size is calculated at a convenient but does not affect mold forming on the premise familiar to simplify the model. The paper also forming part of the stamping dies and other relevant parts of the principle of choice and select the method described. Stamping parts from the design of the first stamping on the production process to be designed to cover iron of chipfor stamping process of analysis and calculation and then calculated on the basis of analysis and see stamping design information related to determine the programme stamping process, and on this basis The process of determining the relationship, and then entered the concrete structure of the die design. On this basis, all of the major parts stamping die design and size, the large number of reference during the relevant information with the press and read all kinds of \structure and Size, by the calculation and constant changes in the careful guidance of teachers under the guidance of patient care and continuously repeated changes to draw the final 1 assembly and 3 parts map. Through this I graduated from design to understand and master the many practical things with my internship in the production of which would like to see some of the things, with some of their own harvest. In this special thanks to college, school teachers for giving me this opportunity and the careful guidance.

Key words: Stamping process, Stamping dies, Sheet metal forming technology, Design calculation
