摘要
冲压模具在实际工业生产中应用广泛。在传统的工业生产中,工人生产的劳动强度大、劳动量大,严重影响生产效率的提高。随着当今科技的发展, 工业生产中模具的使用已经越来越引起人们的重视,而被大量应用到工业生产中来。冲压模具的自动送料技术也投入到实际的生产中,冲压模具可以大大的提高劳动生产效率,减轻工人负担,具有重要的技术进步意义和经济价值。
本模具采用了落料、冲孔两工序复合进行冲压。该套冲压模具设计周密,设计内容全面。包括对冲压件工艺性分析,模具工艺方案的确定,模具零件的设计、受力计算及其校核,模具标准的选定,装配图的绘制,压力机的型号选定等,并综合考虑各种模具结构,最后以最高效率、最低成本、最高质量、最简结构来确定模具的结构,这样的模具操作更加安全、快捷、方便,并且更容易达到冲压件的公差等级要求等。实现了冲压模具用材节省、结构合理、精度高、操作方便等优点。

Abstract
Punching die has been widely used in industrial production. In the traditional industrial production, the worker works very hard and there are too much work for them, so the efficiency is low. With the development of the science and technology nowadays, the use of punching die in the industrial production gain more attention, and be used in the industrial production more and more. Self-acting feed technology of punching die is also used in production, punching die could increase the efficiency of production and could alleviate the work burden,so it has significant meaning in technologic progress and economic value.
This mould is designed by the method of blanking and punching operates in the same plumb axes working procedure, or as posite die .The stamping die’s design cycle is thorough prehensive .Such as pressing part has been made all the necessary full craft analysis, die craft is designed carefully ,craft calculation formulas ,die type and construction are elected prudently ,assemble drawing and parts drawing are reordered time and time again, with prehensively the structures of various moulds ,and finally we confirm the structure of this mould with the criterion of the high efficiency, low cost, high quality and simple structure. With this method the designed die will be used safely, high efficiency and expediently. Mean well, it will be easy to reach the tolerance which the part need, and so on. The die can also satisfy that cost saving, well-knit, easy operation, and so on.
