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；主要是因為，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?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">橢圓封頭為什么比直邊厚主要原因有：1、封頭的加工在設(shè)計上現(xiàn)在不考慮加工減薄量，因此在制造的過程中要另外增加減薄量。板材的常用規(guī)格可能要提檔。2、封頭上一般有開孔，標準的橢圓封頭的計算厚度和筒體基本一但是考慮到開孔補強的問題就會增加厚度，這里主要是指不采用補強圈的問題。封頭與盲板的作用差不多,在施工中要因工程的需要而定。不可拘泥不化。盲板在選用上,對厚度的要求也要注意,眾所周知,封頭是用中板做的。中板的厚度多為下差,如50厚的中板也就是49.5的厚度。20的中板就在19.5甚至是19個的厚度上。一定要根據(jù)實際的需要來選擇封頭的厚度。封頭就是起到一個封死管道的作用。其實這個管道到頭就不準備再用了。如果為以后還想再接管子。就可以用盲板與法蘭盤想配。這樣來封住管子。旋壓法加工封頭的優(yōu)點：設(shè)備、工裝投資較模壓法少。</p><div
