【正文】 9 模具主要零件的設(shè)計(jì)與計(jì)算模具結(jié)構(gòu)的確定這次設(shè)計(jì)主要討論的模具是工序一的落料拉深復(fù)合模模具的形式這次設(shè)計(jì)的落料拉深復(fù)合模采用正裝式復(fù)合模輔助裝置沖壓件的定位，主要由凹模的形狀和尺寸來(lái)保證導(dǎo)向零件采用滑動(dòng)式導(dǎo)柱導(dǎo)套進(jìn)行導(dǎo)向模架采用后側(cè)導(dǎo)柱模架模具閉合高度：最大205㎜，最小170㎜凹凸模長(zhǎng)度設(shè)計(jì)為62㎜，落料凹模厚度設(shè)計(jì)為44㎜，則該模具的實(shí)際閉合高度為：H模=45mm+62mm+44mm+50mm(1+）mm=≈188mm180mm+10mm≦H模≦360mm5mm,190mm≦H模≦355mm所以取沖頭長(zhǎng)度為62mm+3mm=65mm凹模厚度為44mm+4mm=48mm模具零件的結(jié)構(gòu)設(shè)計(jì)工作零件落料凹模 10凸模 11凹凸模卸料板 12壓邊圈推件塊 13 模柄套 支撐板 14 模具的裝配 15 心得 CAD技術(shù)已經(jīng)走向了實(shí)用化，可以將設(shè)計(jì)與生產(chǎn)更為緊密的連接起來(lái)，進(jìn)一步提高生產(chǎn)率。d178。+r=√54178。但考慮到第二次拉伸時(shí)，均采用極限拉深系數(shù)，故需保證較好的拉伸條件，需選用大的圓角半徑。 3優(yōu)化選擇工藝方案及模具形式通過(guò)對(duì)汽車(chē)玻璃升降器外殼的工藝性分析，結(jié)合具體生產(chǎn)條件，優(yōu)化選擇該零件的工藝方案及模具形式，使其盡量滿足工藝性合理，經(jīng)濟(jì)性合算的原則。外殼的形狀表明，零件為拉伸件，所以拉伸為基本工序。㎜為IT10級(jí)。s domestic. Many of our products in their daily lives by the mold to produce , more and more people began to engage in the design of the mold industry, a result, our molddesign level has been further improved and the development of space. With the rapid development of the national economy, the market demand for mold growth, mold of rapid industrial growth, will inevitably bring about the great changes of the mold forms of ownership of industrial enterprises, in additi
