摘 要
随着国家实力的提高，科学技术水平也在不断的提高，当然了我们的模具制造的水平也在不断的科学化发展。其生产方法也在不断的由手动方式改变为利用高科技软件来辅助达到的设计要求，提高了生产的效率。
冷冲模算是其中的一种。
这次设计的主要目的就是，把我们大学四年所学的理论知识和实践知识综合运用起来。
通过自己设计的模具不仅巩固和提高相关专业知识，熟悉模具设计制造的方法、步骤和相关技术要求。而且还锻炼自己如何更有效的查阅相关自己想要，需求的资料也是一种不可或缺的能力。
模具设计与冲压工艺应该从零件的质量、、生产的成本、效率，劳动的强度、环境的保护以及生产的安全性等各个方面综合考虑。选择生产效率高的、生产成本较低的、生产安全的工艺方案和模具。
关键词：模具设计制造； 冲压工艺； 环境保护； 经济合理。

Abstract
With the improvement of national strength, scientific and technological level has been improved, and of course our mold manufacturing level is constantly scientific development. Its production process has also been changed to take advantage of high-tech software to assist achieve the design requirements of the manual mode, improve the efficiency of production. Die regarded as one of them.
The main purpose of this design is that the theoretical and practical knowledge learned our comprehensive four-year university to use them.
Through their own mold design not only consolidate and enhance relevant expertise, familiar with mold design and manufacturing methods, procedures and relevant technical requirements. But also how to more effectively exercise their own access to relevant they want, demand for information is an indispensable capability.
Mold design and stamping process should start with the quality of parts,, various aspects of the production cost, efficiency, intensity of labor, environmental protection and production safety comprehensive consideration. Choose high production efficiency, lower production costs, production safety technology program and die. keywords :
Mould design and manufacture； stamping process； environmental protection； economic and reasonable
引 言
“冲压主要是利用安装在冲压机施加在材料上的压力，以产生塑性变形或分离设备模，而获得一个压力处理方法。”
冲压是工程技术模制材料为材料的加工或塑性加工压力的一种方法。
冲压用于冲压工具模具，简称冲模。只有有了先进的模具，才会有先进的冲压工艺，两者为相辅相成的两个技术。它们只有相互合作才可以得到好的冲压件。
冲压与其他的工艺相比有很多的优点，冲压加工生产效率高，操作方便，易于实现机械化和自动化；不损伤冲压的表面质量，模具寿命一般比较长，冲压质量稳定，互换性效果好，可以处理相对较大的尺寸范围，适用范围比较广。成本还是低的。
很多时候复杂的零件需要大量的模具来加工成型，模具制造精度高，技术要求高，
