軟管總成壓(ya)扣工藝(yi)流程是危害品質(zhi)的關鍵(jian)要(yao)素(su)

危害壓扣式橡膠軟管接頭總成品質的關(guan)鍵(jian)加工(gong)工(gong)藝(yi)要素是(shi)壓(ya)(ya)(ya)扣工(gong)藝(yi)流程。現階段關(guan)鍵(jian)有(you)(you)二種壓(ya)(ya)(ya)扣方法，一種是(shi)軸徑送入式(shi)，可在(zai)通用(yong)(yong)性壓(ya)(ya)(ya)機里用(yong)(yong)專用(yong)(yong)型模貝來完(wan)成。其壓(ya)(ya)(ya)扣量(liang)不容(rong)易調節，在(zai)壓(ya)(ya)(ya)扣全過程中非(fei)常容(rong)易損(sun)害外衣外表層。為了更好(hao)地(di)取下壓(ya)(ya)(ya)扣件。務必(bi)把(ba)模貝制成對開啟(qi)式(shi)。這就會有(you)(you)合縫，使制成品外型不太好(hao)。另(ling)一種為軸向壓(ya)(ya)(ya)扣式(shi)其模貝有(you)(you)兩開、三瓣(ban)(ban)、六(liu)瓣(ban)(ban)和(he)八瓣(ban)(ban)模之分(fen)。合適大批量(liang)生產(chan)一般(ban)用(yong)(yong)六(liu)瓣(ban)(ban)和(he)八瓣(ban)(ban)模貝，確保(bao)壓(ya)(ya)(ya)扣品質的基本是(shi)恰當(dang)把(ba)握橡(xiang)膠(jiao)(jiao)軟管(guan)的內膠(jiao)(jiao)縮(suo)小量(liang)和(he)外衣的壓(ya)(ya)(ya)扣量(liang)。

其中(zhong)孔規格盡可能超過提(ti)高(gao)層(ceng)規格，不然沒(mei)法(fa)裝進(jin)，乃(nai)至會導致提(ti)高(gao)層(ceng)完全(quan)散(san)頭狀(zhuang)況。一般空隙(xi)為１～１.５ｍｍ。外衣內部的(de)槽(cao)形會立(li)即危害接頭品質。現(xian)階段有直孔無槽(cao)體式、鋸(ju)齒(chi)(chi)狀(zhuang)槽(cao)體式及其環狀(zhuang)和鋸(ju)齒(chi)(chi)狀(zhuang)槽(cao)整體式。棉繩（化(hua)學(xue)纖維）手工(gong)編織(zhi)橡膠軟管(guan)因(yin)應用(yong)工(gong)作壓(ya)(ya)力低，拔脫力小(xiao)，都(dou)選用(yong)無槽(cao)體式構(gou)造(zao)。不銹(xiu)鋼絲(si)手工(gong)編織(zhi)橡膠軟管(guan)在壓(ya)(ya)扣時其提(ti)高(gao)層(ceng)易造(zao)成彎折形變(bian)，多選用(yong)鋸(ju)齒(chi)(chi)狀(zhuang)。不銹(xiu)鋼絲(si)螺旋波紋管(guan)一般疊加層(ceng)數較(jiao)多，提(ti)高(gao)層(ceng)的(de)單側薄厚較(jiao)大 達到３.６ｍｍ，壓(ya)(ya)扣時要(yao)使提(ti)高(gao)層(ceng)產生波浪狀(zhuang)形變(bian)而置入槽(cao)體就務(wu)必選用(yong)環狀(zhuang)和鋸(ju)齒(chi)(chi)狀(zhuang)槽(cao)相(xiang)組(zu)成，這類槽(cao)形比鋸(ju)齒(chi)(chi)狀(zhuang)槽(cao)寬(kuan)２／３，其抗拔脫力更(geng)強。
