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的，這也增加了生產成本，2、在容器封頭限制中，其形狀應盡量簡單，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，并且恰當的增大圓角半徑，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。南京原液儲罐封頭企業(yè)封頭的加工在設計上現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。</p><div

style="text-indent:25px">封頭加熱溫度一般不宜超過420度，當式件溫度降至300度以下時，不適宜繼續(xù)熱成形。鈦封頭應該盡量采用熱成形，如成型溫度約為300度－400度。高溫熱成形時工件加熱溫度可以提高到大約650度，但不應該超過800度。冷成形后的熱校形溫度為100－350度。不銹鋼封頭的厚度愈大，隨著產品形狀變量的增多，強度和抗拉強度增卓著進步，硬度值增加，耐塑性下降，產生了卓著的加工硬化現象。不銹鋼封頭對金屬坯料施加外力，使其產生塑性變形、改變尺寸、外形及改善機能。</p><p style="text-indent:25px">封頭冷加工的特點和封頭熱加工的特點比較：1、未經加熱，不會發(fā)生材質劣化，特別適合不銹鋼封頭加工。因加熱，會發(fā)生材質劣化，導致不銹鋼封頭耐腐蝕性下降，不適合不銹鋼封頭加工。2、未經加熱，不會產生冷卻收縮導致的尺寸變化，形狀規(guī)整，尺寸精確且一致性好。加熱成形，導致模具受熱膨脹和封頭冷卻收縮，尺寸難以控制且一致性差。3、未經加熱，封頭成形后表面維持原有材料的光潔表面，外觀漂亮。因加熱，封頭成形后的表面氧化皮嚴重，且難以去除。封頭初度運轉時，要供認電動機滾動的方向是不是精確。</p><div

style="text-indent:25px">封頭與其它的產品不大一樣，主要是用在各種容器兩端，無論是壓制的原材料還是制造后的檢驗都要非常清楚，這樣在事后有什么問題的時候可以探查是哪里出了問題。要如何來解決!所以制造封頭的材料應有用以檢驗和追蹤的確認標記。在制造過程中，如原有確認標記被裁掉或材料分成了幾塊，應在切割前完成標記的移植。確認標記的表達方式由封頭制造單位規(guī)定并且要滿足以下兩點要求：1、對于不銹鋼及復合鋼板制封頭，鋁，鈦，銅，鎳及鎳合金制封頭以及復合材料制封頭，不得在其耐蝕面采用硬印作為材料的確認標記和焊工標志；鈦材及鈦鋼復合板的標記、標志還應符合JB/T4745的有關規(guī)定。2、對于鋼制低溫壓力容器用封頭及需要進行疲勞分析設計的封頭，不得采用硬印作為材料的確認標記和焊工標志。雖然這些都是比較小的細節(jié)方面，但是只有將每一步小細節(jié)都做好了才能決定大步驟的發(fā)展浙江粉罐運輸車封頭廠家聯系方式</p><p
