拉伸件的種類很多，由于其形狀不同，其變形區(qū)的位置、變形的性質(zhì)、坯料各部分的應(yīng)力應(yīng)變狀態(tài)和分布規(guī)律等都有相當(dāng)大的差別，有些甚至是本質(zhì)上的區(qū)別。 1、拉伸過(guò)程中，福田質(zhì)量精密拉伸五金件加工，坯料的凸緣部分是主要變形區(qū)，其余部分只發(fā)生少量變形，但要承受并傳遞拉伸力，故是傳力區(qū)； 2、變形區(qū)受切向壓應(yīng)力和徑向拉應(yīng)力作用，產(chǎn)生切向壓縮和徑向伸長(zhǎng)變菜。當(dāng)變形程度較大時(shí)，變形區(qū)主要發(fā)生失穩(wěn)起皺現(xiàn)象。 3、拉伸件的壁厚不均勻，口部壁厚略有增厚，底部壁厚略有減薄，福田質(zhì)量精密拉伸五金件加工，靠近底部圓角處變薄嚴(yán)重； 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，福田質(zhì)量精密拉伸五金件加工，冷作硬化小，故度也低。奧氏體不銹鋼為亞穩(wěn)定型，在變形時(shí)會(huì)出現(xiàn)變相，誘發(fā)馬氏體相；福田質(zhì)量精密拉伸五金件加工</p><div style="width:100%;text-align:

沖壓拉伸加工中為什么要用塑性好的金屬材料？這取決于塑性材料的拉伸變形量。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> <p> <br /> </p> <p> 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(jiàn)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(kāi)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(guò)一段時(shí)間的存放或者使用中出現(xiàn)開(kāi)裂。
