摘 要
我的这次论文内容是通过给定的任务设计的。完成冲压工艺的方法是通过我的查询资料和指导老师的辅导下以及对相应的产品的大小、形状、质量深入研究分析的基础上决定完成的;该设计的模具则是通过我在仔细深入的分析研究过该产品的经济性、以及该产品需要的冲压工艺性和该产品设计的复杂程度和一系列的因素的仔细研究后开始着手的;该零件的其毛坯的展开的尺寸的数据设计则是通过我在易于设计并且不会阻碍到该产品的模具成型的重要前提下变得更简单来为我们更常见的简单模型来设计的。本篇论文包含了对冲压成型产品以及其它类似的产品的选择原则及选择方法有专门的介绍和描述,其中还包含描述了几种零件的形状的毛坯展开尺寸数据的设计的手段以及它的简化模型,另外还包含了为了完成冲压模具设计我需要查询的几本参考书。

Abstract
The content of my thesis is given the task by design. Complete stamping process is by my query information and guidance teacher's guidance and the basis of the corresponding product size, shape, quality, in-depth research and analysis on the decision to complete; the design of the mold is through my carefully depth analysis through a careful study of the complexity of the product of the economy, as well as the stamping process of product needed and the product design and a range of factors began; it blank to expand the size of the part of the design data by my easy to design and do not hinder the next important prerequisite for the molding product becomes easier for us to the more common simple model to design. This paper contains a press-molded product selection principles and selection methods and other similar products have a special presentation and description, which also contains the description of the shape of the several parts of the means of blank expanding size of the data and its simplified design model, also included in order to complete my need, stamping die design of several reference books.
