设计简介
摘 要
随着社会生产力的提高与发展，现如今模具制造中的冲压加工已经是一种非常成熟的金属加工方法。它具有操作简单、精度高、产品一致性好、生产效率高、材料利用率高和用于大批量生产等特点。本次毕业设计根据已经确定的冲载件即双耳止动垫片的尺寸进行冲载工艺的分析及设计，从而得到冲载工艺。根据已经确定好的冲载工艺进行凸凹模结构参数的计算与设计，并根据文献资料最终确定级进模的凸凹模结构。根据设计好的凸凹模结构选择标准零件和模架，从而完成模具的设计并校核。完成模具设计后，用UG软件完成模具的三维模型并采用AutoCAD软件完成模具装配图的制图。本次毕业设计还独立完成与专业相关且不少于4万字符的指定英文资料翻译。通过本次毕业设计，我系统的学习和掌握了模具设计的知识和制造加工工艺的编制技术。我采用了较好的设计思想和设计方法，成功的完成了双耳止动垫片冲孔落料级进模的毕业设计。

Abstract
With the improvement and development of social productive forces, the stamping of Mold Manufacturing now is already a very advanced metal processing methods. It has the feature of simple operation, high accuracy, product consistency, high production efficiency, high utilization of materials and for mass production and so on. The graduation project bases on the pieces（binaural washer）of punch set that have been identified in binaural washer dimensions for analysis and design of the craft of punch set resulting in getting the craft of punch. I will do the job of calculation and design of structural parameters punch basing on the craft of punch set that has been determined，and ultimately determine the progressive of punch structure of Progressive Die according to the literature. I select the standard parts and the mold according to the designed structure of punch structure .Thus completing the mold design. After the completion of mold design, I use UG software to complete three-dimensional model and use AutoCAD software to complete the graphics of mold assembly drawing. The graduation project is independently complete not less than40,000 characters of the specified English translation associated with professional. Through this graduation design, I learn systematically and mastered the preparation of technical of manufacturing process and knowledge of mold design. I used the advanced design concepts and design methods, and I successfully complete the graduate design of Binaural Washer Punching and Blanking Progressive Die Design.
