有凸緣筒形件沖壓成形工藝及模具設計摘 要：本論文介紹了拉深的成形方法和條件，拉深是利用拉深模在壓力機的壓力作用下，將平板坯料或空心工序件制成開口空心件的加工方法。旋轉體拉深時的應力應變分析，還有拉深過程中的 起皺和拉裂。拉深件毛坯的尺寸計算，和工藝計算，以及拉深次數(shù)的計算。 拉深模結構相對較簡單。根據(jù)拉深模使用的壓力機類型不同，拉深模可分為單動壓力機用拉深模和雙動壓力機拉深模；根據(jù)拉深順序分為首次拉深和以后各次拉深；根據(jù)工序組合可分為單工序拉深、復合工序拉深和連續(xù)工序拉深；根據(jù)壓料情況可分為有壓邊裝置和無壓邊裝置拉深。從模具設計到零部件的加工工藝以及裝配工藝等進行詳細的闡述，并應用 CAD進行各重要零件的設計。關鍵詞：工藝分析；拉深成型；模具裝配；模具結構A flange cylinder Stamping process and Die DesignAbstract： The paper introduced to pull to take shape method and condition deeply, pulling is the pressure function that the exploitation pulls a deep mold in the pressure machine deeply under, anticipate flat panel or the hollow work preface piece make in to open mouth a hollow piece to process a method.Revolving the body pulls deep hour of should dint contingency analysis, also have already pulled deep process in of shrivel and pull crack.Pull a deep piece the size calculation of the semi-finished product, and the craft compute, and pull the calculation of deep number of times. Pull deep mold structure opposite more simple.According to pull the pressure machine type dissimilarity that the deep mold uses, pulling the deep mold can is divided into a list to move pressure machine to use to pull deep mold and double to move pressure machine to pull a deep mold;According to pull deeply in proper order is divided into for the very first time pull deeply with later each one pull deeply;According to the work preface combination can is divided into a single work preface to pull deeply, compound the work preface pull to deeply pull with continuous work preface deeply;According to pressing to anticipate a circumstance can is divided in to press side device and don't press side device to pull deeply.Design to zero partses to process a craft and assemble craft's etc. to carry on to elaborate in detail from the molding tool, and the design applied CAD to carry on each important spare parts.Key Words：Craft analysis; Pull to model deeply; The molding tool assembles; Molding tool structure
