1、拉伸過程中，坯料的凸緣部分是主要變形區(qū)，福田本地精密拉伸五金件的用途和特點(diǎn)，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變菜，福田本地精密拉伸五金件的用途和特點(diǎn)。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，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，冷作硬化小，福田本地精密拉伸五金件的用途和特點(diǎn)，故度也低。原材料要冷卻到50°以下才能移到拉伸架上進(jìn)行拉伸加工。福田本地精密拉伸五金件的用途和特點(diǎn)</p><div style="width:100%;text-align: center;"><img

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 /> </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)會出現(xiàn)開裂有時(shí)會出現(xiàn)拉伸變形后；有時(shí)會在拉伸件由凹模內(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。
