1、 湖南工業大學本科生畢業設計（論文）帶槽三角形固定板沖圓孔、沖槽、落料連續模設計院 （系）：機械工程學院專 業：學 號：學生姓名：指導教師：2010年5月摘要本設計進行了沖圓孔、沖槽、落料連續模的設計。文中簡要概述了沖壓模具目前的發展狀況和趨勢。對產品進行了詳細工藝分析和工藝方案的確定。按照沖壓模具設計的一般步驟，計算并設計了本套模具上的主要零部件，如：凸模、凹模、凸模固定板、墊板、凹模固定板、卸料板、導尺、擋料銷、導正銷等。模架采用標準模架，選用了合適的沖壓設備。設計中對工作零件和壓力機規格均進行了必要的校核計算。此外，本模具采用始用擋料銷和圓形擋料銷擋料。落料凸模內裝有導正銷，保證了工件上

2、孔和外形的相對位置準確，提高了加工精度。如此設計出的結構可確保模具工作運行可靠和沖壓產品大批量生產的要求。 關鍵詞：連續模；沖壓模具；標準模架；沖壓設備；校核；沖孔；落料ABSTRACTThis design carried on has flushed circle hole, flushes the trough, falls the material continual mold the design. In the article has briefly outlined the ramming mold at present development condition and the

3、 tendency. Has carried on the detailed craft analysis and the craft plan determination to the product. According to general step which the ramming mold designs, calculated and has designed on this set of molds main spare part, for example: The raised mold, the concave mold, the raised mold dead plat

4、e, the backing strip, the concave mold dead plate, unloads, leads the ruler, keeps off the material to sell, to lead is selling and so on. The mold frame uses the standard mold frame, has selected the appropriate ramming equipment. In the design has carried on the essential examination computation t

5、o the work components and the press specification. In addition, this mold uses the beginning with to keep off the material to sell with the circular keeps off the material. the concave mold and falls the material concave mold to use the overall dead plate to be fixed. Fell the material raised mold i

6、nternal installation to have leads is selling, had guaranteed on the work piece the hole and the contour relative position was accurate, increased the processing precision. So designs the structure may guarantee the mold work movement to be reliable and the ramming product mass production request.Ke
