摘     要
冲压制品已在工业、农业、国防和日常生活中的方面得到广泛应用,特别是在机械业中更为突出。机械产品的外壳大部分是冲压制品，产品性能的提高要求高质量的冲压模具和冲压性能，成型工艺和制品的设计。
冲压制品的成型方法很多。其主要用于是冲孔，落料，弯曲，拉伸等。而冲压模，约占成型总数的60％以上。当然如利用电气控制，可实现半自动化或自动化作业。
冷冲压冲裁模主要用于金属制品的成型，它是冲压制品生产中十分重要的工艺装置。冲压模的基本组成是：上下模座、模具垫板、下模固定板、凹模镶块、抬料钉、导料板、导柱导套、卸料板弹钉、卸料板等。
通过对冲裁图样零件的工艺性的正确分析，设计了一个连续冲裁冲孔落料模。本设计介绍了模具成型零件包括凸模、凹模及其他零件，如卸料板、固定板、垫板、导柱、导套等的设计和选用过程，重要零件的工艺参数的选择与计算，冲裁机构与送料挡料以及其它结构的设计过程，并对着重对模具的设计部分作了详细介绍。

The blanking dies design of fixed plate
Abstract:  
Stamping products has been extensively applied in the industry, agriculture, national defense and in the daily lives of area, especially in the machinery industry. mechanical products is the most pressing housing products, and the improvement of product performancer equires of high-qualityp erformance stamping molds ,stamping,process and product design.
There are many ways of molding products of stamping. It is mainly used for piercing ,blanking, bending, stretching etc. And stamping molds almost form more than 60 percent of the total number. For example ,electrical control can be realized as semi-automatic or automatic operation.
Cold-metal stamping die mainly used for the metal products, and it is very important in the production of stamping technology devices. The basic component of stamping molds is block model from top to bottom, backing strip，fixed-plate of mould, die inserts, raising nails, plate unloading, guidepillars and guide bushes, unloading bombs nail plate, stripper plate and so on.
Through to technological correct analysis of the blanking patterns components, has designed a continual blanking punching die blanking . This design introduced the mold formation components including the plunger, the lower die and other components like unload the yard lumber, the dead plate, the backing strip, the guide pillar, the guide busher and so on design and select the process, the technological parameter's choice and the computation of the important components, the blanking organization and the feeding keep off the material as well as other structure design process, and to has made the detailed introduction emphatically to mold's design parts.
