產(chǎn)品的質(zhì)量和性能與其生產(chǎn)過程密不可分。為了保證產(chǎn)品質(zhì)量，有必要控制生產(chǎn)過程。以沖壓拉伸模為例。在生產(chǎn)中，其生產(chǎn)過程一般具有以下特點(diǎn)： </p> <p> <br /> </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，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，每個(gè)沖壓沖程可獲得一個(gè)沖頭。 </p> <p> <br /> 多次拉伸可以提高產(chǎn)品的合格率，不容易產(chǎn)生廢品，多次拉伸的中間去應(yīng)力，退火軟化。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="羅湖防腐精密拉伸五金件價(jià)格多少,精密拉伸五金件"
