1、拉伸加工：使用壓板裝置，利用凸模的沖壓力，將平板材的一部分或者全部拉入凹模型腔內(nèi)，使之成形為帶底的容器。容器的側(cè)壁與拉伸方向平行的加工，是單純的拉伸加工，福田精密拉伸五金件加工，福田精密拉伸五金件加工，而對(duì)圓錐(或角錐)形容器、半球形容器及拋物線面容器等的拉伸加工，其中還包含擴(kuò)形加工。 </p> <p> <br /> </p> <p> 2，福田精密拉伸五金件加工、再拉伸加工：即對(duì)一次拉伸加工無法完成的深拉伸產(chǎn)品，需要將拉伸加工的成形產(chǎn)品進(jìn)行再次拉伸，以增加成形容器的深度。 </p> <p> <br /> </p> <p> <br /> 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。福田精密拉伸五金件加工</p><div

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">錐形拉伸加工：h/d>0.8、α =10°～30°的深錐形件，由于深度較大，坯料的變形程度較大，*靠坯料與凸模接觸的局部面積傳遞成形力，極易引起坯料局部過度變薄乃至破裂，需要經(jīng)過多次過渡逐漸成形。階梯拉伸法是首先將坯料拉伸成階梯形過渡件，其階梯外形與錐形部的內(nèi)形相切，***脹形成錐形。階梯過渡件的拉伸次數(shù)、工藝等與階梯圓筒件的拉伸相同。矩形再拉伸加工：多次拉伸成形的高矩形件，其變形不*與深圓筒形件的拉伸不同，與低盒形件的變形也有很大差別。圖1-46為多工位自動(dòng)搬送壓力機(jī)進(jìn)行高矩形盒件加工時(shí)，多次拉伸過程中制件外形、尺寸伴隨拉伸高度的變化。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。</p><div

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。便于散熱均勻，從而減少橫向亮斑。南山耐磨精密拉伸五金件的用途和特點(diǎn)</p><p
