軟管總成壓扣工藝流程是(shi)危害品質的關鍵要素(su)

危害壓扣式橡膠軟管接頭總成(cheng)(cheng)品(pin)質的(de)關鍵加工(gong)工(gong)藝(yi)要素(su)是(shi)壓(ya)(ya)(ya)扣(kou)工(gong)藝(yi)流程(cheng)。現(xian)階段關鍵有(you)二種壓(ya)(ya)(ya)扣(kou)方法，一(yi)種是(shi)軸徑送入式，可在通用(yong)性壓(ya)(ya)(ya)機里用(yong)專用(yong)型(xing)(xing)模(mo)貝(bei)來完成(cheng)(cheng)。其壓(ya)(ya)(ya)扣(kou)量(liang)(liang)不容易調(diao)節，在壓(ya)(ya)(ya)扣(kou)全(quan)過(guo)程(cheng)中非常容易損害外(wai)衣外(wai)表層。為了(le)更好地取下壓(ya)(ya)(ya)扣(kou)件。務(wu)必(bi)把模(mo)貝(bei)制成(cheng)(cheng)對開啟式。這就(jiu)會有(you)合(he)縫(feng)，使制成(cheng)(cheng)品(pin)外(wai)型(xing)(xing)不太好。另一(yi)種為軸向壓(ya)(ya)(ya)扣(kou)式其模(mo)貝(bei)有(you)兩開、三瓣(ban)(ban)(ban)、六(liu)瓣(ban)(ban)(ban)和(he)八瓣(ban)(ban)(ban)模(mo)之分。合(he)適大批量(liang)(liang)生產一(yi)般(ban)用(yong)六(liu)瓣(ban)(ban)(ban)和(he)八瓣(ban)(ban)(ban)模(mo)貝(bei)，確保壓(ya)(ya)(ya)扣(kou)品(pin)質的(de)基本是(shi)恰(qia)當把握橡膠軟管的(de)內膠縮小量(liang)(liang)和(he)外(wai)衣的(de)壓(ya)(ya)(ya)扣(kou)量(liang)(liang)。

其中孔規格盡(jin)可(ke)能超過(guo)提(ti)高(gao)層(ceng)規格，不(bu)然沒法裝進(jin)，乃至會導致提(ti)高(gao)層(ceng)完全散頭狀(zhuang)況。一(yi)般空(kong)隙為１～１.５ｍｍ。外(wai)衣(yi)內部的(de)槽(cao)(cao)(cao)形(xing)會立即(ji)危害(hai)接頭品質。現階(jie)段有直孔無槽(cao)(cao)(cao)體(ti)(ti)(ti)式(shi)(shi)、鋸齒(chi)狀(zhuang)槽(cao)(cao)(cao)體(ti)(ti)(ti)式(shi)(shi)及其環狀(zhuang)和鋸齒(chi)狀(zhuang)槽(cao)(cao)(cao)整(zheng)體(ti)(ti)(ti)式(shi)(shi)。棉繩（化學(xue)纖(xian)維）手工(gong)(gong)編(bian)織(zhi)橡(xiang)膠軟(ruan)管因應用(yong)工(gong)(gong)作壓(ya)力低，拔脫(tuo)力小，都選用(yong)無槽(cao)(cao)(cao)體(ti)(ti)(ti)式(shi)(shi)構造(zao)。不(bu)銹(xiu)鋼絲手工(gong)(gong)編(bian)織(zhi)橡(xiang)膠軟(ruan)管在壓(ya)扣時其提(ti)高(gao)層(ceng)易造(zao)成(cheng)彎折形(xing)變，多選用(yong)鋸齒(chi)狀(zhuang)。不(bu)銹(xiu)鋼絲螺旋波紋管一(yi)般疊(die)加層(ceng)數較(jiao)多，提(ti)高(gao)層(ceng)的(de)單(dan)側薄厚較(jiao)大 達到３.６ｍｍ，壓(ya)扣時要使提(ti)高(gao)層(ceng)產(chan)生波浪狀(zhuang)形(xing)變而(er)置入槽(cao)(cao)(cao)體(ti)(ti)(ti)就務必選用(yong)環狀(zhuang)和鋸齒(chi)狀(zhuang)槽(cao)(cao)(cao)相(xiang)組成(cheng)，這(zhe)類槽(cao)(cao)(cao)形(xing)比鋸齒(chi)狀(zhuang)槽(cao)(cao)(cao)寬(kuan)２／３，其抗拔脫(tuo)力更強。
