球形封頭的淬火方式主要有那些？

?? 球(qiu)形(xing)封頭一般主要(yao)以開口朝上的(de)入水(shui)方式(shi)淬火。上封頭、底封頭等一般為厚度均(jun)勻、形(xing)狀規則的(de)球(qiu)冠形(xing)狀，并且球(qiu)形(xing)表面為封閉(bi)結構(gou)。其淬火方式(shi)主要(yao)有以下(xia)幾種：

（1）料(liao)(liao)盤淬(cui)火(huo)方(fang)式。此類封頭(tou)淬(cui)火(huo)之前預(yu)先設計(ji)一個淬(cui)火(huo)料(liao)(liao)盤，料(liao)(liao)盤中間根據封頭(tou)尺寸設計(ji)一個合理大小(xiao)直徑(jing)的透孔(kong)(kong)，淬(cui)火(huo)加熱以及(ji)入水時將封頭(tou)開口(kou)朝(chao)上坐于透孔(kong)(kong)上，透孔(kong)(kong)大小(xiao)保證封頭(tou)底(di)面不超(chao)出料(liao)(liao)盤底(di)面，為保證熱均勻以及(ji)隨(sui)后淬(cui)火(huo)的冷卻效率，料(liao)(liao)盤的其它部位(wei)合理的開一定大小(xiao)的透孔(kong)(kong)。淬(cui)火(huo)時，用天車(che)平(ping)穩吊(diao)起料(liao)(liao)盤浸入水中；

（2）焊(han)吊鉤淬(cui)火方式。淬(cui)火之前(qian)，先在封頭開(kai)口端每(mei)隔(ge)90°均勻(yun)焊(han)接四個相同的吊鉤，淬(cui)火時(shi)(shi)用(yong)四個吊鉤同時(shi)(shi)將鍛(duan)件(jian)吊起，這樣可以在一定程度上防止封頭過度變形，球形封頭廠(chang)，能夠(gou)更加平穩的將封頭浸入(ru)水(shui)(shui)中[5]，但是淬(cui)火時(shi)(shi)封頭內會有積水(shui)(shui)；

（3）料圈(quan)(quan)淬火方式(shi)。料圈(quan)(quan)淬火方式(shi)其(qi)(qi)實(shi)與料盤淬火方式(shi)類似，由于料盤的制造相對(dui)要(yao)復雜費工，可以(yi)將其(qi)(qi)簡化為(wei)料圈(quan)(quan)形式(shi)，省(sheng)時且節(jie)約(yue)成(cheng)本。根據封(feng)頭尺寸制作一較封(feng)頭開口端直徑小的料圈(quan)(quan)，淬火時用(yong)料圈(quan)(quan)從(cong)封(feng)頭底側(ce)套起，用(yong)單(dan)臂吊(diao)托住(zhu)料圈(quan)(quan)將封(feng)頭浸入(ru)水中。

以上3種方(fang)式，均可使(shi)封(feng)頭(tou)外表面獲得較(jiao)好的(de)冷(leng)(leng)卻效(xiao)果，但是封(feng)頭(tou)的(de)內(nei)表面由(you)于封(feng)頭(tou)的(de)形狀，較(jiao)容易存水(shui)，不(bu)能(neng)及時將水(shui)排走，使(shi)熱量部分儲(chu)存，使(shi)本(ben)來就冷(leng)(leng)卻較(jiao)慢的(de)內(nei)側的(de)冷(leng)(leng)卻能(neng)力進一步降低，影(ying)響了內(nei)表面尤其是底(di)面的(de)冷(leng)(leng)卻效(xiao)果。

不過受(shou)到形(xing)狀及材(cai)質要求，所以半球封頭在(zai)使用(yong)時應注意一些要求：

1、半球封頭的成形減薄率比橢圓形封頭要大些，正常的熱成形工藝，球形封頭制造廠，減薄率在10%左右。這點是由于不同封頭廠生產工藝不同所導致的，如果對此有詳細要求的話，應進行定制。2、對于半球封頭的材質來說，如果有特殊要求的可以按照要求進行定制。3、半球封頭的大小會有不同，亦可根據用戶要求進行定做。 球形封頭廠-貴州球形封頭-力拓封頭廠家由泰安力拓封頭制造有限公司提供。泰安力拓封頭制造有限公司是山東 泰安 ,工業鍋爐及配件的見證者，多年來，公司貫徹執行科學管理、創新發展、誠實守信的方針，滿足客戶需求。在力拓封頭領導攜全體員工熱情歡迎各界人士垂詢洽談，共創力拓封頭更加美好的未來。
