4、拉伸件各部分硬度也不一樣，口部變形程度大，冷作硬化嚴(yán)重，故硬度較高；而底部變形程度小，冷作硬化小，故度也低。中山精密拉伸五金件的用途和特點(diǎn)例如同等的拉伸高度，如果選擇塑性比較差的金屬材料，就需要用更多的拉伸步距或中途退火。</p><div style="width:100%;text-align: center;"><img style="max-width:

style="text-indent:25px">精密五金拉伸件是比較難做的，***它的精密度要求高，第二表面光潔度要求也高；第三和普通的拉伸件相比較是很小的。零件的精度能達(dá)到0.03mm,表面光潔度可到達(dá)0.8mm。如此高精密的工件，需要多年經(jīng)驗(yàn)的師傅才能做出來(lái)。禾聚精密沖壓拉伸件可以保證其公差為±0.01mm，折彎尺寸為±0.03mm內(nèi)，選用拉伸油的方法有四種，硅鋼板是比較容易拉伸的材料，為了工件成品的易清洗性，在防止劃痕產(chǎn)生的前提下會(huì)選用低粘度的沖壓油。碳鋼板在選用拉伸油時(shí)首先應(yīng)該注意的是拉伸油的粘度。根據(jù)工藝難易度和脫脂條件來(lái)決定較佳粘度。鋁合金拉伸件具有優(yōu)良的導(dǎo)電性、導(dǎo)熱性和抗蝕性。珠海防腐精密拉伸五金件哪里買(mǎi)</p><p style="text-indent:25px">鋁合金拉伸件加工注意事項(xiàng)有：在取料、移動(dòng)、拉伸中材料不能相互碰擦。寶安本地精密拉伸五金件模具</p><p> 拉伸件成型沖壓加工是禾聚精密的六大技術(shù)之一，技術(shù)特點(diǎn)：拉伸公差可達(dá)±0.015mm、外觀無(wú)瑕疵、可做到R/T＜1.0。拉伸件應(yīng)用于機(jī)械、電子、電器、儀表、汽車、航空、**產(chǎn)品。 </p> <p> <br /> </p> <p> 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 /> 寶安本地精密拉伸五金件模具</p><p
