style="text-indent:25px">橢圓封頭劃傷主要是在搬運(yùn)過程中，操作不當(dāng)引起的。例如：吊鉤劃痕，叉車劃痕。解決方法：先在吊鉤和叉車與封頭接觸面墊保護(hù)膜，出現(xiàn)劃傷后，進(jìn)行打磨，嚴(yán)重的進(jìn)行補(bǔ)焊，劃傷面積超過百分之二十五要整體處理。如何增加橢圓封頭減薄率？成型封頭的厚度均勻可以避免應(yīng)力集中，增加封頭的使用周期，根據(jù)制造工藝確定加工裕量，以確保凸形封頭和熱卷筒節(jié)成形后的厚度不小于該部件的名義厚度減去鋼板負(fù)偏差。橢圓封頭大多數(shù)的橘皮現(xiàn)象出于板材本身有分層現(xiàn)象，然而肉眼是觀察不出來的，只能是在沖壓，壓鼓工序中，橘皮現(xiàn)象才能被發(fā)現(xiàn)。封頭的功能是非常強(qiáng)大的，適用于多種場(chǎng)合。</p><div

style="text-indent:25px">不銹鋼封頭在質(zhì)量外觀上有哪些特殊要求呢？我現(xiàn)在就為大家簡(jiǎn)要介紹一下。首先不銹鋼封頭在產(chǎn)品質(zhì)量上的控制其實(shí)和一般的封頭沒有什么太大區(qū)別。不銹鋼封頭一般的生產(chǎn)流程為：不銹鋼封頭材料的進(jìn)料、理化、材質(zhì)的下料、產(chǎn)品的熱鍛成型、產(chǎn)品熱處理；封頭一般的檢驗(yàn)步驟為：產(chǎn)品檢驗(yàn)、產(chǎn)品的精加工、封頭成品的檢驗(yàn)、標(biāo)識(shí)、再成品的檢驗(yàn)、再標(biāo)識(shí)；包裝步驟：包裝前進(jìn)行打字、之后再進(jìn)行發(fā)運(yùn)。不銹鋼封頭通常用于緊固比較多種類汽車的尾氣管,這種產(chǎn)品也與某些產(chǎn)品例如一種錐度螺母，它可以用于緊固汽車尾氣管裝置。這種設(shè)備和裝置至少包括不銹鋼封頭內(nèi)與汽車尾氣管相連的隔熱圈,隔熱圈安裝在橢圓型不銹鋼管內(nèi)與汽車尾氣管外的中間,不銹鋼管一頭做成錐度外螺紋且開均分三瓣內(nèi)也錐度,旋錐度螺母越緊對(duì)隔熱圈密封也越緊機(jī)械連接。不銹鋼封頭用于下列產(chǎn)品，也就是雙出氣口管道內(nèi)與各類型尾氣管進(jìn)氣口處有緊固錐度螺母緊固裝置機(jī)械連接。解決了尾氣管裝置容易生銹、影響汽車美觀的問題。結(jié)構(gòu)簡(jiǎn)單、裝拆方便,使單管排氣轎車變成雙管后尾部看過去更氣魄,普遍應(yīng)用于各種轎車的尾氣管上。南通吸收塔封頭加工</p><p
