在拉伸件拉伸成型工藝中，有一次拉伸成型和多次拉伸成型。一次拉伸的特點(diǎn)是一次成型，可以提高生產(chǎn)效率，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。 </p> <p> <br /> </p> <p> 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。多次拉伸可以確保工件的精度，延伸系數(shù)以及生產(chǎn)效率都得到很大程度的提高。多次拉伸可以拉的更加勻稱，降低工件的不良率。 </p> <p> <br /> 這兩種特殊水泥涂層均適用于沖壓拉伸件的內(nèi)防腐，提高抵抗侵蝕的能力。光明精密拉伸五金件模具</p><p

拉深件的工序數(shù)量與材料性質(zhì)、拉深高度、拉深階梯數(shù)以及拉深直徑、材料厚度等條件有關(guān)，需經(jīng)拉深工藝計算才能確定。當(dāng)拉深件圓角半徑較小或尺寸精度要求較高時，則需在拉深后增加一道整形工序，精密小五金拉伸件工藝大致可分為分離工序和成形工序。 </p> <p> <br /> </p> <p> 分離工序是在沖壓過程中使其與坯料沿一定的輪廓線相互分離，同時五金沖壓件分離斷面的質(zhì)量也要滿足一定的要求。 </p> <p> <br /> </p> <p> 成形工序是使沖壓坯料在不破壞的條件下發(fā)生變形，并轉(zhuǎn)化成所要求的五金沖壓件形狀，同時也應(yīng)滿足尺寸公差等方面的要求。 </p> <p> <br /> </p> <p> <br />
