選擇拉伸材料中，要注意屈服點(diǎn)、抗拉強(qiáng)度的比值越小，拉深性能越好，一次變形的極限程度越大越有利于降低成本以及保證拉伸的質(zhì)量。不銹鋼拉伸是拉伸工藝中經(jīng)常見到的，很多拉伸件經(jīng)常用到不銹鋼。但由于不銹鋼的延展率比較小，彈性模量也比較大，硬化**比較高。拉伸時(shí)會(huì)出現(xiàn)開裂有時(shí)會(huì)出現(xiàn)拉伸變形后；有時(shí)會(huì)在拉伸件由凹模內(nèi)退出的時(shí)候發(fā)生；有時(shí)在拉伸變形后受到撞擊或者振動(dòng)時(shí)才出現(xiàn)；有時(shí)在拉伸變形后經(jīng)過一段時(shí)間的存放或者使用中出現(xiàn)開裂。 </p> <p> <br /> </p><p style="text-indent:25px">變薄拉伸加工（Ironing）：與普通拉伸不同，變薄拉伸主要是在拉伸過程中改變拉伸件筒壁的厚度。凸凹模之間的間隙小于毛坯厚度，毛坯直壁部分在通過間隙時(shí)，處于較大的均勻壓應(yīng)力之下，拉伸過程中壁厚變薄的同時(shí)，消除容器壁厚偏差，增加容器表面的光滑度，提高精度和強(qiáng)度面板拉伸加工（Panel drawing）：面板產(chǎn)品是板材沖壓件，表面形狀復(fù)雜。在拉伸工序中，毛坯變形復(fù)雜，其成形性質(zhì)已非簡(jiǎn)單的拉伸成形，而是拉深與脹形同時(shí)存在的復(fù)合成形。鋁酸鹽水泥涂層或***鹽水泥涂層。</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。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決定較佳粘度。這樣可以有效地避免在使用過程中發(fā)生腐蝕現(xiàn)象。深圳耐磨精密拉伸五金件模具</p><p
