style="text-indent:25px">容器封頭都有其加工特色和工藝性，那么在容器封頭中拉伸件的特色和工藝性是怎么樣的呢？下面簡單說一下 1、容器封頭的各個部分的尺度比例要合適，一般淺拉伸件比較好加工，如果遇到有凸緣和深度較大的容器封頭時，我們是需要較多的拉伸次數(shù)的，這也增加了生產(chǎn)成本，2、在容器封頭限制中，其形狀應(yīng)盡量簡單，并且對稱；主要是因?yàn)?，軸對此的拉伸件，在圓周方向上是有均勻變形的，并且簡單容器封頭也是好加工的；3、在拉伸容器封頭中，其圓角半徑也要適宜，拉伸件的底與壁、凸緣與壁等都要滿足一定的要求，并且恰當(dāng)?shù)脑龃髨A角半徑，還能夠有利于成形；4、要確保容器封頭的厚度均勻，其上面孔的位置也要合理。</p><p style="text-indent:25px">不銹鋼封頭在使用前要進(jìn)過一定的加工處理，比如不銹鋼封頭表面的處理，只有處理好表面的不銹鋼封頭的加工過程之中涉及處理不銹鋼氧化層的酸洗膏,尤其涉及在常溫下清理不銹鋼封頭氧化層并使其表面鈍化的酸洗膏.不銹鋼由于其耐腐蝕,有一定的機(jī)械強(qiáng)度和導(dǎo)熱性能,而被普遍應(yīng)用在各個領(lǐng)域.其需求量日趨增大.但是,不銹鋼封頭一經(jīng)熱處理或焊接等,其表面會形成一層堅(jiān)硬的灰黑色氧化層.這使得不銹鋼封頭材料既不美觀,耐腐蝕性也差.給進(jìn)一步加工和應(yīng)用帶來比較大的不便.目前世界上多采用酸洗膏對這層氧化層進(jìn)行化學(xué)處理.它們在使用過程中會出現(xiàn)煙霧,容易濺射到操作者手上,灼傷人的皮膚,同時對環(huán)境造成污染.本品既能去除不銹鋼氧化層,使不銹鋼封頭表面鈍化,同時對使用者的皮膚腐蝕輕微,在使用過程中不會產(chǎn)生煙霧.使用過的殘余物便于回收處理,使用方便.涂在不銹鋼封頭氧化層表面上(約3MM厚),在常溫下需20-50分鐘,用水潤濕表面,片刻后用塑料刷刷除之,即露出已鈍化的不銹鋼光潔表面.本品尤其適用于清理1Cr18Ni9Ti型不銹鋼氧化層。清理的殘余物可用氧化鈣中和處理之。封頭液壓設(shè)備設(shè)備完成后，按照闡明書給設(shè)備增加必定的油。</p><div
