style="text-indent:25px">封頭用以制造機(jī)械零件、工件、工具或毛坯的成形加工方法。不銹鋼封頭鍛造的受力面積會(huì)有所減少，所需要的荷載也會(huì)降低；當(dāng)加工硬化達(dá)一定程度時(shí)，如繼承形變，便有開(kāi)裂或脆斷的危險(xiǎn)，成形后其殘余應(yīng)力極易引起工件自爆破裂。擺輾、擺旋鍛和輾環(huán)也可用精鍛加工。不銹鋼封頭的承受壓力，恢復(fù)力是封頭一個(gè)重要的參數(shù)，承受壓力低可能會(huì)導(dǎo)致使用中封頭有開(kāi)裂的情況發(fā)生。如果我們提高橢圓不銹鋼封頭的加工溫度，再改變其大小，同時(shí)在變形的時(shí)候?qū)⑾鄳?yīng)的壓制區(qū)域變大，還可以將它的量控制在一定程度。封頭有手動(dòng)和自動(dòng)之分，各自的效用也是不一樣的。</p><div
