一般(ban)使(shi)用(yong)(yong)(yong)(yong)(yong)(yong)橢(tuo)圓(yuan)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)，球(qiu)(qiu)(qiu)形(xing)(xing)(xing)(xing)(xing)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)替代橢(tuo)圓(yuan)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)的(de)(de)(de)原因： 1、特殊材(cai)料(liao)，貴。 我們有(you)(you)2個4200的(de)(de)(de)N10276封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)，用(yong)(yong)(yong)(yong)(yong)(yong)橢(tuo)圓(yuan)須(xu)32mm，用(yong)(yong)(yong)(yong)(yong)(yong)球(qiu)(qiu)(qiu)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)18mm，可(ke)節省(sheng)約300W。 2、一般(ban)材(cai)料(liao)，厚。 用(yong)(yong)(yong)(yong)(yong)(yong)球(qiu)(qiu)(qiu)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)節省(sheng)材(cai)料(liao)，一般(ban)超過(guo)40mm就可(ke)考(kao)慮(lv)(lv)用(yong)(yong)(yong)(yong)(yong)(yong)球(qiu)(qiu)(qiu)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)。 3、一般(ban)材(cai)料(liao)，大(da)(da)，厚。封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)成(cheng)型困難，一般(ban)采(cai)(cai)用(yong)(yong)(yong)(yong)(yong)(yong)瓜瓣式，先(xian)成(cheng)型，再拼焊，做球(qiu)(qiu)(qiu)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)容(rong)易(yi)。 無論(lun)從壓力(li)還(huan)是直(zhi)徑(jing)方面都很難確定(ding)采(cai)(cai)用(yong)(yong)(yong)(yong)(yong)(yong)橢(tuo)圓(yuan)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)或球(qiu)(qiu)(qiu)形(xing)(xing)(xing)(xing)(xing)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)的(de)(de)(de)一個界(jie)限。 有(you)(you)時(shi)多看(kan)看(kan)實際的(de)(de)(de)裝(zhuang)置(zhi)會有(you)(you)一些啟發(fa)。現在的(de)(de)(de)熱壁(bi)加氫反應(ying)器都是球(qiu)(qiu)(qiu)形(xing)(xing)(xing)(xing)(xing)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)，氣相(xiang)法線(xian)性低(di)密(mi)度聚乙烯、聚反應(ying)器（筒(tong)(tong)(tong)(tong)(tong)體(ti)直(zhi)徑(jing)3500）雖(sui)然壓力(li)不大(da)(da)高但(dan)也(ye)用(yong)(yong)(yong)(yong)(yong)(yong)的(de)(de)(de)是球(qiu)(qiu)(qiu)形(xing)(xing)(xing)(xing)(xing)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)。曾(ceng)做過(guo)氫氣罐(guan)雖(sui)然只有(you)(you)幾立方米，直(zhi)徑(jing)900，但(dan)壓力(li)較(jiao)高20多MPa，安徽球(qiu)(qiu)(qiu)形(xing)(xing)(xing)(xing)(xing)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)，也(ye)用(yong)(yong)(yong)(yong)(yong)(yong)了球(qiu)(qiu)(qiu)形(xing)(xing)(xing)(xing)(xing)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)。 我想當你需要考(kao)慮(lv)(lv)改(gai)善封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)力(li)及(ji)筒(tong)(tong)(tong)(tong)(tong)體(ti)應(ying)狀況的(de)(de)(de)時(shi)候優先(xian)考(kao)慮(lv)(lv)用(yong)(yong)(yong)(yong)(yong)(yong)球(qiu)(qiu)(qiu)形(xing)(xing)(xing)(xing)(xing)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)。較(jiao)多的(de)(de)(de)情(qing)況是工藝(yi)條件(jian)已(yi)經定(ding)了結構形(xing)(xing)(xing)(xing)(xing)式。 因為(wei)球(qiu)(qiu)(qiu)形(xing)(xing)(xing)(xing)(xing)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)的(de)(de)(de)深度比(bi)(bi)(bi)橢(tuo)圓(yuan)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)大(da)(da)，如(ru)果是大(da)(da)直(zhi)徑(jing)的(de)(de)(de)需要拼接的(de)(de)(de)球(qiu)(qiu)(qiu)形(xing)(xing)(xing)(xing)(xing)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)，在沖(chong)的(de)(de)(de)時(shi)候有(you)(you)可(ke)能會把焊縫(feng)沖(chong)開。所(suo)以不好加工。 GB150中為(wei)什么將(jiang)球(qiu)(qiu)(qiu)形(xing)(xing)(xing)(xing)(xing)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)與(yu)筒(tong)(tong)(tong)(tong)(tong)體(ti)的(de)(de)(de)環縫(feng)定(ding)為(wei)A類(lei)？ 因為(wei)球(qiu)(qiu)(qiu)形(xing)(xing)(xing)(xing)(xing)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)的(de)(de)(de)周向(xiang)應(ying)力(li)和(he)縱(zong)向(xiang)應(ying)力(li)是相(xiang)等的(de)(de)(de)， 計算(suan)厚度比(bi)(bi)(bi)圓(yuan)筒(tong)(tong)(tong)(tong)(tong)體(ti)小將(jiang)近一半。球(qiu)(qiu)(qiu)形(xing)(xing)(xing)(xing)(xing)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)與(yu)筒(tong)(tong)(tong)(tong)(tong)體(ti)連接處(chu)一般(ban)是將(jiang)筒(tong)(tong)(tong)(tong)(tong)體(ti)削薄(bo)， 連接焊縫(feng)處(chu)的(de)(de)(de)縱(zong)向(xiang)應(ying)力(li)應(ying)該不小于(yu)筒(tong)(tong)(tong)(tong)(tong)體(ti)縱(zong)縫(feng)處(chu)的(de)(de)(de)周向(xiang)應(ying)力(li)， 所(suo)以球(qiu)(qiu)(qiu)形(xing)(xing)(xing)(xing)(xing)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)頭(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)與(yu)筒(tong)(tong)(tong)(tong)(tong)體(ti)的(de)(de)(de)環縫(feng)和(he)筒(tong)(tong)(tong)(tong)(tong)體(ti)縱(zong)縫(feng)一樣(yang)屬于(yu)A類(lei)焊縫(feng)。

球形封頭是怎樣的沖壓過程？

 將(jiang)封(feng)頭毛(mao)(mao)坯(pi)(pi)(pi)(pi)對(dui)中(zhong)放在下模(mo)上，然后開(kai)動(dong)(dong)水壓(ya)(ya)機使活動(dong)(dong)橫(heng)梁空程向下，當壓(ya)(ya)邊(bian)圈與(yu)毛(mao)(mao)坯(pi)(pi)(pi)(pi)接觸后，開(kai)動(dong)(dong)壓(ya)(ya)邊(bian)鋼將(jiang)毛(mao)(mao)坯(pi)(pi)(pi)(pi)的邊(bian)緣壓(ya)(ya)緊(jin)。接著上模(mo)空程下降，當與(yu)毛(mao)(mao)坯(pi)(pi)(pi)(pi)接觸時，開(kai)動(dong)(dong)主缸使上模(mo)向下沖(chong)壓(ya)(ya)，對(dui)毛(mao)(mao)坯(pi)(pi)(pi)(pi)進(jin)行拉(la)伸，至毛(mao)(mao)坯(pi)(pi)(pi)(pi)完全通過下模(mo)后，封(feng)頭便(bian)沖(chong)壓(ya)(ya)成形(xing)。   

 對后開動提(ti)升(sheng)缸和(he)回程缸，將上(shang)模(mo)和(he)壓(ya)邊圈向上(shang)提(ti)起，碳鋼球形封(feng)頭(tou)(tou)廠(chang)家(jia)，與(yu)(yu)此同時用(yong)脫模(mo)裝置(zhi)將包在上(shang)模(mo)上(shang)的封(feng)頭(tou)(tou)脫下，并(bing)將球形封(feng)頭(tou)(tou)從(cong)下模(mo)支座下取出，沖壓(ya)過程即告結(jie)束(shu)。并(bing)且(qie)，我廠(chang)家(jia)還(huan)是(shi)一家(jia)生(sheng)產球形封(feng)頭(tou)(tou)的廠(chang)家(jia)，可根據型(xing)號(hao)進行制作，如果您有這方面的需(xu)要(yao)，可與(yu)(yu)我們聯系(xi)。  

       半(ban)(ban)(ban)球封頭是封頭的一(yi)種，主要是它的外形(xing)是半(ban)(ban)(ban)球的形(xing)狀，因此(ci)得名(ming)。半(ban)(ban)(ban)球封頭主要用于壓力容器上作為堵塞裝(zhuang)置使用。

       封頭是指用以封閉容器端部使其內外介質隔離的元件，又稱端蓋。圓筒形容器的封頭一般都是迥轉殼體。按封頭表面的形狀可分為凸形、錐形、平板形和組合形。凸形封頭是指外表面形狀為凸面的封頭，如半球形、橢圓形、碟形和無折邊球形封頭等。有的氣瓶采用凸面向內的組合形底封頭，既可保證強度，又能滿足安全使用的耍求。 球形封頭批發價-力拓封頭(在線咨詢)-安徽球形封頭由泰安力拓封頭制造有限公司提供。球形封頭批發價-力拓封頭(在線咨詢)-安徽球形封頭是泰安力拓封頭制造有限公司今年新升級推出的，以上圖片僅供參考，請您撥打本頁面或圖片上的聯系電話，索取聯系人：趙經理。
