【正文】 hnology programs, and then painting process maps, calculated choice stamping equipment . Then select the type of die structure, followed by a number of die design of the relevant data, including some of the basic puting power. Punch on the mold, die machining process, as well as processing program to determine the final preparation of convexity modulus of order processing. The design of the analysis and solution of the parts manufacturing process and convex and concave mold manufacturing technology and processes arrangements.Key words:Composite mold;assembly;technology programs;process arrangements目 錄1 沖壓工藝設(shè)計(jì)………………………………………………1 ………………………………………1 …………………………………………2 ……………………………………2 …………………………………………2 …………………………………………2 …………………………………………2 …………………………………………3 …………………………………………3 …………………………………………3 …………………………………………3 ………………………………………42 復(fù)合模具的設(shè)計(jì) …………………………………………5 …………………5 …………………………………………6(落料凸模)尺寸的確定 ……………6(沖孔凹模)尺寸的確定 ………………6……………7 ………………………………73 模具主要零件加工工藝設(shè)計(jì)………………………………8(拉深凹模)加工工藝過(guò)程 …………………9(沖孔凹模)加工工藝過(guò)程…………………11………………………………11………………………………124 模具的工作過(guò)程 …………………………………………145 設(shè)計(jì)體會(huì) …………………………………………………15參考文獻(xiàn)………………………………………………………161 沖壓工藝設(shè)計(jì)通過(guò)對(duì)零件圖的觀察,知零件的形狀、尺寸及板料的材料和厚度。此模具是落料、拉深和沖孔相結(jié)合的復(fù)合模具。大多軋制成高精度的薄板或冷軋鋼帶用以制造易加工成形,強(qiáng)度低的深沖壓或深拉延的覆蓋零件和焊接構(gòu)件。零件名稱(chēng)產(chǎn)品型號(hào)文件型號(hào)零件代號(hào)每臺(tái)件數(shù)1共 頁(yè)第 頁(yè)材料08鋼 t=條料140mm2000mm材料利用率單件140mm139mm48%工序工卡工序或工卡內(nèi)容加工草圖設(shè)備1剪床下料2落料200KN壓力機(jī)3拉深200KN壓力機(jī)4沖孔200KN壓力機(jī)5檢驗(yàn)游標(biāo)卡尺2 復(fù)合模具的設(shè)計(jì)復(fù)合模具分為正裝式和倒裝式復(fù)合模具兩種。但沖孔廢料落在沖模工作面上,不易排除。因此,當(dāng)工件材料厚度較薄而要求平整時(shí),一般采用倒裝式復(fù)合模具,用彈性卸料板。查凸、凹模的制造偏差表得:凸模偏差=,凹模偏差=查雙面間隙值表得:= (mm),= (mm)由于+== (mm)所以取凸模偏差=()=,凹模偏差=()
