1、容器封頭的各個(gè)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(shí)，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(jiǎn)單，并且對(duì)稱；主要是因?yàn)?，軸對(duì)此的拉伸件，在圓周方向上是有均勻變形的，并且簡(jiǎn)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，浙江換熱設(shè)備封頭生產(chǎn)制造廠家，還能夠有利于成形；4，浙江換熱設(shè)備封頭生產(chǎn)制造廠家，浙江換熱設(shè)備封頭生產(chǎn)制造廠家、要確保容器封頭的厚度均勻，其上面孔的位置也要合理。半球形封頭常用在高壓容器上。浙江換熱設(shè)備封頭生產(chǎn)制造廠家</p><div
