軟管總成壓扣(kou)工藝流程(cheng)是危害品質的關鍵要素

危害壓扣式橡膠軟管接頭總成(cheng)(cheng)品(pin)質的關(guan)鍵(jian)加工(gong)工(gong)藝(yi)要素是壓扣(kou)工(gong)藝(yi)流程。現階段關(guan)鍵(jian)有(you)二種壓扣(kou)方法，一種是軸徑送入(ru)式，可(ke)在(zai)通用(yong)(yong)性壓機里用(yong)(yong)專用(yong)(yong)型(xing)模(mo)貝來完成(cheng)(cheng)。其(qi)壓扣(kou)量不容(rong)(rong)易調節，在(zai)壓扣(kou)全過程中非常容(rong)(rong)易損(sun)害外(wai)(wai)衣外(wai)(wai)表層。為了(le)更好(hao)地取下(xia)壓扣(kou)件(jian)。務必(bi)把(ba)模(mo)貝制(zhi)成(cheng)(cheng)對(dui)開啟式。這就會有(you)合縫，使制(zhi)成(cheng)(cheng)品(pin)外(wai)(wai)型(xing)不太好(hao)。另一種為軸向壓扣(kou)式其(qi)模(mo)貝有(you)兩開、三瓣(ban)、六(liu)瓣(ban)和(he)(he)八瓣(ban)模(mo)之分。合適大批(pi)量生產一般用(yong)(yong)六(liu)瓣(ban)和(he)(he)八瓣(ban)模(mo)貝，確保壓扣(kou)品(pin)質的基本(ben)是恰(qia)當把(ba)握橡(xiang)膠軟(ruan)管的內膠縮小量和(he)(he)外(wai)(wai)衣的壓扣(kou)量。

其中孔(kong)規(gui)格(ge)盡可能(neng)超過提高層規(gui)格(ge)，不(bu)然沒(mei)法裝進，乃至會導致提高層完全散頭狀(zhuang)況。一(yi)般空(kong)隙為(wei)１～１.５ｍｍ。外衣內部的(de)(de)槽形(xing)會立即危害接頭品質。現階段有直孔(kong)無(wu)(wu)槽體式、鋸(ju)(ju)齒(chi)狀(zhuang)槽體式及其環(huan)狀(zhuang)和(he)鋸(ju)(ju)齒(chi)狀(zhuang)槽整體式。棉(mian)繩（化學纖維）手工(gong)編織橡膠(jiao)軟(ruan)管(guan)因應(ying)用(yong)(yong)工(gong)作壓(ya)力低(di)，拔脫(tuo)力小，都(dou)選用(yong)(yong)無(wu)(wu)槽體式構造。不(bu)銹(xiu)鋼絲手工(gong)編織橡膠(jiao)軟(ruan)管(guan)在壓(ya)扣時其提高層易造成(cheng)彎折(zhe)形(xing)變，多選用(yong)(yong)鋸(ju)(ju)齒(chi)狀(zhuang)。不(bu)銹(xiu)鋼絲螺旋波(bo)紋管(guan)一(yi)般疊加層數較多，提高層的(de)(de)單側薄厚(hou)較大 達到３.６ｍｍ，壓(ya)扣時要(yao)使提高層產生波(bo)浪(lang)狀(zhuang)形(xing)變而置入槽體就務必選用(yong)(yong)環(huan)狀(zhuang)和(he)鋸(ju)(ju)齒(chi)狀(zhuang)槽相(xiang)組成(cheng)，這類槽形(xing)比鋸(ju)(ju)齒(chi)狀(zhuang)槽寬２／３，其抗拔脫(tuo)力更強。
