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，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">球形封頭的放樣方法：定義如下：D0=1000，δm=2，h=0（為了便于演示，h定義為零），H=250步驟如下：1、畫出構(gòu)件的主視圖及其構(gòu)件的斷面圖。2、將斷面圖分成若干等份。這里取24份。3、將主視圖一根素線分成若干等份。這里取6份。由等分點(diǎn)向斷面圖引若干垂線，交斷面圖水平線段若干點(diǎn)。并以斷面圖圓心為圓心，以圓心到垂足的距離為半徑作若干圓。4、以所選的素線的長(zhǎng)度畫一條豎直的線段。并分成和素線相等的份數(shù)。素線長(zhǎng)為605.501這里是6份。5、在所作的若干圓上截取相應(yīng)的同心圓弧的長(zhǎng)度，為了下料方便，把弧長(zhǎng)轉(zhuǎn)化成線段的長(zhǎng)度，按順序分別添加到素線的等分點(diǎn)上。6、對(duì)用弧長(zhǎng)的和用線段的進(jìn)行比較，如圖3得之，用弧長(zhǎng)的稍比用線段的長(zhǎng)一些。如圖4較大差值*為0.2mm。因此為了下料方便我們可以取，用線段表示的方法畫近似瓜瓣。7、在這里，大家都可以理解，素線的等分點(diǎn)越多，那么放樣得到的就越接近實(shí)際尺寸。無(wú)限等分后的結(jié)果就是實(shí)際瓜瓣。但是我們做不到，只能根據(jù)實(shí)際情況，按照客戶或其他原因，選取n的等分點(diǎn)進(jìn)行放樣。封頭擁有非常強(qiáng)的防腐蝕能力。</p><div
