摘     要
沖壓制品已在工業(yè)、農(nóng)業(yè)、國防和日常生活中的方面得到廣泛應(yīng)用,特別是在機械業(yè)中更為突出。機械產(chǎn)品的外殼大部分是沖壓制品，產(chǎn)品性能的提高要求高質(zhì)量的沖壓模具和沖壓性能，成型工藝和制品的設(shè)計。
沖壓制品的成型方法很多。其主要用于是沖孔，落料，彎曲，拉伸等。而沖壓模，約占成型總數(shù)的60％以上。當(dāng)然如利用電氣控制，可實現(xiàn)半自動化或自動化作業(yè)。
冷沖壓沖裁模主要用于金屬制品的成型，它是沖壓制品生產(chǎn)中十分重要的工藝裝置。沖壓模的基本組成是：上下模座、模具墊板、下模固定板、凹模鑲塊、抬料釘、導(dǎo)料板、導(dǎo)柱導(dǎo)套、卸料板彈釘、卸料板等。
通過對沖裁圖樣零件的工藝性的正確分析，設(shè)計了一個連續(xù)沖裁沖孔落料模。本設(shè)計介紹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、墊板、導(dǎo)柱、導(dǎo)套等的設(shè)計和選用過程，重要零件的工藝參數(shù)的選擇與計算，沖裁機構(gòu)與送料擋料以及其它結(jié)構(gòu)的設(shè)計過程，并對著重對模具的設(shè)計部分作了詳細(xì)介紹。

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.
