錐形件落料拉深工藝及模具設(shè)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(jī)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(zhuǎn)體拉深時的應(yīng)力應(yīng)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(jié)構(gòu)相對較簡單。根據(jù)拉深模使用的壓力機(jī)類型不同，拉深?？煞譃閱蝿訅毫C(jī)用拉深模和雙動壓力機(jī)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(fù)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(shè)計到零部件的加工工藝以及裝配工藝等進(jìn)行詳細(xì)的闡述，并應(yīng)用 CAD 進(jìn)行各重要零件的設(shè)計。關(guān)鍵詞：工藝分析；拉深成型；模具裝配；模具結(jié)構(gòu)錐形件落料拉深工藝及模具設(shè)計 ABSTRACT： 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
