【正文】 剛性卸料與彈性卸料的比較：剛性卸料是采用固定卸料板結構。 操作與定位方式 操作方式零件的生產批量較大，但合理安排生產可用手工送料方式，也能滿足生產要求，這樣就可以降低生產成本，提高經濟效益。但級進模輪廓尺寸較大，制造較復雜，成本較高，一般適用于大批量生產小型沖壓件。其中，方案一模具結構簡單，但需要四副單工序模，成本高而生產效率低，難以滿足大批量生產要求。采用單工序模生產。零件凸緣上均布著六個的小孔和底孔，為了保證孔的位置準確和精度，其加工放在拉深結束后沖裁。由于本人水平有限，缺乏實踐經驗，所以在設計中難免產生不足和錯誤，望各位老師批評和指正，以使我的畢業(yè)設計做到合理，同時也為我走出校門步入社會打下堅實的基礎。本次設計是在周愛嬌老師認真、耐心的指導和同學們的幫助、交流下，對模具的經濟性、模具的壽命、生產周期、及生產成本等指標下進行全面、仔細的分析下而進行設計的。在近三個月的設計中，為了更好地完成任務，期間還到工廠進行了實習，參觀了沖壓模具的生產加工過程，這加強了我們的感性認識，更有利于我們完成模具設計。由于我沒有實踐經驗所以很多東西都要依靠手冊。首先，先對零件進行工藝分析與計算，其中包含工藝分析與設計方案的確定，確定排樣，計算沖裁力與選擇沖壓設備等。關鍵詞：模具，沖孔，落料，拉深Stamping process and die designAbstract：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 performance requires of highquality performance stamping molds ,stamping,process and product design. There are many ways of molding products of stamping. Piercing is mainly used for 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 semiautomatic or automatic operation. Coldmetal stamping die mainly used for the molding products, and it is very important in the production of stamping technology devices. The basic ponent of stamping molds is block model from top to bottom, mould plate, fixedplate of mould plate, die inserts, raising nails, I. plate, plate unloading I. Introduction sets column, unloading bombs nail plate, plate Discharge and so on. The widely application of blank
