</p> <p> 1.沖壓拉伸件模具可用于加工尺寸范圍大、形狀復(fù)雜的零件，如鐘表等小秒表、汽車縱梁、覆蓋件等。由于沖壓過程中材料的冷變形和硬化效應(yīng)，沖壓的強(qiáng)度和剛度較高。 </p> <p> <br /> </p> <p> 2.沖壓時(shí)，模具保證了沖壓件尺寸和形狀的準(zhǔn)確性，一般不會(huì)損壞沖壓件的表面質(zhì)量，模具使用壽命長。因此，沖壓質(zhì)量穩(wěn)定，互換性好，具有“一模一樣”的特點(diǎn)。 </p> <p> <br /> </p> <p> 3.沖壓一般不產(chǎn)生切屑，材料消耗少，龍華本地精密拉伸五金件哪里好，龍華本地精密拉伸五金件哪里好，不需要其他加熱設(shè)備，是一種節(jié)省材料和能源的加工方法，沖壓件成本較低。 </p> <p> <br /> </p> <p> 4.本發(fā)明生產(chǎn)效率高，操作方便，易于實(shí)現(xiàn)機(jī)械化和自動(dòng)化。這是因?yàn)闆_壓是通過沖壓模具和沖壓設(shè)備來完成的。普通壓力機(jī)的沖程數(shù)可達(dá)到每分鐘幾十次，高速壓力可達(dá)到每分鐘幾百次甚至幾千次，龍華本地精密拉伸五金件哪里好，每個(gè)沖壓沖程可獲得一個(gè)沖頭。 </p> <p> <br /> 缺點(diǎn)是一次成型容易不到位，而且每次拉伸的變化程度是有要求的，不能變化太大。龍華本地精密拉伸五金件哪里好</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="龍華本地精密拉伸五金件哪里好,精密拉伸五金件"

</p> <p> <br /> </p> <p> 拉伸件總之是比較有技術(shù)含量的模具類型，不管是對(duì)設(shè)計(jì)、加工、組裝、還是調(diào)試都是一個(gè)挑戰(zhàn)，需要十分謹(jǐn)慎。 </p> <p> <br />

style="text-indent:25px">拉伸系數(shù)非常重要，一個(gè)拉伸件需要分幾步拉伸才能保證不出現(xiàn)開裂、起皺等問題都需要用拉伸系數(shù)公式進(jìn)行計(jì)算。是拉伸工藝核算中的首要工藝參數(shù)之一，一般用它來決議拉伸的次序和次數(shù)。但是，拉伸系數(shù)也不是固定不變的。影響拉伸系數(shù)的因素比較多，其中包括：材料型號(hào)、厚度、拉伸結(jié)構(gòu)類型、拉伸次數(shù)、拉伸速度、拉伸鑲件圓弧過度大小等等。不過，一般都可以查表進(jìn)行大概計(jì)算。拉伸件在調(diào)試模具過程中經(jīng)常會(huì)遇到拉裂、起皺等問題。如果出現(xiàn)拉裂，需要考慮材料流動(dòng)問題，可以在凹模上涂潤滑油不要在凸模涂，或者在產(chǎn)品靠凹模一面覆0.013--0.018mm的薄膜就是鉗工師傅常用的纏繞膜。則皺，少則裂，按此方法判斷材料的流動(dòng)情況。調(diào)整方案：調(diào)整壓邊圈的壓力、增加拉深筋、改變上下模鑲件的圓弧過度半徑、工件上切工藝口等。拉伸件總之是比較有技術(shù)含量的模具類型，不管是對(duì)設(shè)計(jì)、加工、組裝、還是調(diào)試都是一個(gè)挑戰(zhàn)，需要十分謹(jǐn)慎。</p><p
