軟管總成壓(ya)扣工(gong)藝流程是危害品質(zhi)的關鍵要素

危害壓扣式橡膠軟管接頭總成(cheng)(cheng)品(pin)質的(de)關鍵加工工藝要(yao)素(su)是壓(ya)(ya)扣(kou)工藝流程(cheng)。現階段(duan)關鍵有(you)二種(zhong)壓(ya)(ya)扣(kou)方法，一種(zhong)是軸徑送入式(shi)，可在(zai)通用性壓(ya)(ya)機里用專用型(xing)(xing)模(mo)貝(bei)來完成(cheng)(cheng)。其壓(ya)(ya)扣(kou)量(liang)(liang)不容易調節，在(zai)壓(ya)(ya)扣(kou)全過程(cheng)中非(fei)常容易損害外(wai)衣(yi)外(wai)表層(ceng)。為了更(geng)好(hao)地取下壓(ya)(ya)扣(kou)件。務必(bi)把模(mo)貝(bei)制(zhi)(zhi)成(cheng)(cheng)對開(kai)啟(qi)式(shi)。這就會有(you)合縫，使制(zhi)(zhi)成(cheng)(cheng)品(pin)外(wai)型(xing)(xing)不太(tai)好(hao)。另(ling)一種(zhong)為軸向壓(ya)(ya)扣(kou)式(shi)其模(mo)貝(bei)有(you)兩開(kai)、三瓣(ban)、六瓣(ban)和八(ba)瓣(ban)模(mo)之(zhi)分(fen)。合適(shi)大批量(liang)(liang)生產一般用六瓣(ban)和八(ba)瓣(ban)模(mo)貝(bei)，確保(bao)壓(ya)(ya)扣(kou)品(pin)質的(de)基本是恰當把握橡(xiang)膠軟管的(de)內膠縮(suo)小量(liang)(liang)和外(wai)衣(yi)的(de)壓(ya)(ya)扣(kou)量(liang)(liang)。

其(qi)(qi)中孔規格(ge)(ge)盡可能(neng)超過提(ti)高層(ceng)規格(ge)(ge)，不(bu)然(ran)沒法裝進，乃至會(hui)(hui)導致(zhi)提(ti)高層(ceng)完全(quan)散(san)頭(tou)狀況(kuang)。一般空(kong)隙為１～１.５ｍｍ。外(wai)衣內部的槽形(xing)(xing)會(hui)(hui)立即危害接頭(tou)品質。現階段有直孔無槽體(ti)式、鋸齒(chi)(chi)狀槽體(ti)式及其(qi)(qi)環(huan)狀和(he)鋸齒(chi)(chi)狀槽整(zheng)體(ti)式。棉繩（化(hua)學纖維）手工(gong)(gong)編(bian)織橡膠軟管(guan)因應用(yong)(yong)工(gong)(gong)作壓力低，拔(ba)脫力小，都選(xuan)(xuan)用(yong)(yong)無槽體(ti)式構(gou)造。不(bu)銹鋼(gang)絲手工(gong)(gong)編(bian)織橡膠軟管(guan)在壓扣時(shi)其(qi)(qi)提(ti)高層(ceng)易造成(cheng)彎折形(xing)(xing)變，多選(xuan)(xuan)用(yong)(yong)鋸齒(chi)(chi)狀。不(bu)銹鋼(gang)絲螺旋波紋管(guan)一般疊加層(ceng)數較多，提(ti)高層(ceng)的單(dan)側薄厚(hou)較大 達到３.６ｍｍ，壓扣時(shi)要使提(ti)高層(ceng)產生(sheng)波浪狀形(xing)(xing)變而置(zhi)入槽體(ti)就務必選(xuan)(xuan)用(yong)(yong)環(huan)狀和(he)鋸齒(chi)(chi)狀槽相組成(cheng)，這類槽形(xing)(xing)比鋸齒(chi)(chi)狀槽寬２／３，其(qi)(qi)抗拔(ba)脫力更強。
