0028-端蓋拉深成形工藝及模具設(shè)計(jì)（落料拉伸復(fù)合模設(shè)計(jì)）,端蓋拉深,成形,工藝,模具設(shè)計(jì),拉伸,復(fù)合,設(shè)計(jì) 端蓋的沖壓工藝及模具設(shè)計(jì) 摘要：此次畢業(yè)設(shè)計(jì)任務(wù)是端蓋零件的模具設(shè)計(jì)。端蓋為有凸緣圓筒形件，是典型的拉深件，其拉深過程中變形區(qū)的應(yīng)力狀態(tài)和變形特點(diǎn)與無凸緣圓筒形件是相同的，但有凸緣圓筒形件拉深時(shí)，胚料凸緣部分不是全部進(jìn)入凹模洞口，當(dāng)拉深進(jìn)行到凸緣外徑等于零件凸緣直徑時(shí)，拉深工作就停止。 良好的工藝性和合理的工藝方案，可以用最少的材料，最少的工序和工時(shí)，使得模具結(jié)構(gòu)簡單且模具壽命長，能穩(wěn)定的獲得合格沖裁件，通過分析端蓋的工藝性，確定合理的工藝方案；通過計(jì)算端蓋的相對直徑或者相對高度，判斷端蓋能否一次拉深成功，從而確定拉深工藝參數(shù)以及模具工作部分的幾何形狀與尺寸；根據(jù)計(jì)算結(jié)果選用標(biāo)準(zhǔn)表架。 關(guān)鍵詞：端蓋 應(yīng)力狀態(tài) 工藝性 工藝方案 拉深次數(shù) Gasket ramming craft and mold design Abstract：This mission is designed graduate washers parts mold design. Gaskets for flange cylinder-shaped pieces, is typical of drawing parts, Drawing its process of deformation of stress and deformation characteristics and without flange cylinder-shaped pieces are the same. But flange cylinder-shaped drawing, blank flange is not something all entered Die holes When drawing for diameter of the flange to flange diameter parts, drawing on the work to stop. Good technology and good process, with the least material, at least the processes and working hours. make simple structure Die Mold longevity, stability can be qualified blanking through analysis of the washers, determine reasonable process; By calculating the relative diameter washers or relative height, Can a judge washers Drawing successful, in order to determine drawing process parameters and die part of the geometric shape and size; According to the results table-selection criteria.
