軟管總成壓扣工藝流程是危害品質(zhi)的關鍵要素

危害壓扣式橡膠軟管接頭總成品(pin)質的(de)關鍵(jian)加工(gong)工(gong)藝要素是壓(ya)扣(kou)工(gong)藝流(liu)程(cheng)。現階段關鍵(jian)有(you)二種(zhong)壓(ya)扣(kou)方法(fa)，一種(zhong)是軸徑送入式，可在通用(yong)(yong)性壓(ya)機里用(yong)(yong)專用(yong)(yong)型(xing)模(mo)(mo)(mo)貝(bei)來完(wan)成。其壓(ya)扣(kou)量不容(rong)易調(diao)節，在壓(ya)扣(kou)全(quan)過程(cheng)中(zhong)非常容(rong)易損害外(wai)(wai)衣外(wai)(wai)表(biao)層。為(wei)了更好地取下壓(ya)扣(kou)件。務必(bi)把模(mo)(mo)(mo)貝(bei)制成對開(kai)啟式。這(zhe)就會有(you)合縫，使制成品(pin)外(wai)(wai)型(xing)不太好。另一種(zhong)為(wei)軸向壓(ya)扣(kou)式其模(mo)(mo)(mo)貝(bei)有(you)兩(liang)開(kai)、三瓣(ban)(ban)、六瓣(ban)(ban)和八(ba)瓣(ban)(ban)模(mo)(mo)(mo)之分。合適大批量生產一般用(yong)(yong)六瓣(ban)(ban)和八(ba)瓣(ban)(ban)模(mo)(mo)(mo)貝(bei)，確保壓(ya)扣(kou)品(pin)質的(de)基本是恰(qia)當把握橡(xiang)膠軟管的(de)內膠縮小(xiao)量和外(wai)(wai)衣的(de)壓(ya)扣(kou)量。

其(qi)(qi)中孔(kong)規格盡可能超過提(ti)高(gao)(gao)層(ceng)(ceng)規格，不然沒法裝進，乃至會導致提(ti)高(gao)(gao)層(ceng)(ceng)完全散(san)頭狀況。一般空隙為(wei)１～１.５ｍｍ。外(wai)衣內(nei)部的槽(cao)(cao)形會立即(ji)危害接頭品(pin)質。現階段有直孔(kong)無槽(cao)(cao)體(ti)(ti)式(shi)、鋸(ju)齒(chi)(chi)狀槽(cao)(cao)體(ti)(ti)式(shi)及其(qi)(qi)環狀和(he)鋸(ju)齒(chi)(chi)狀槽(cao)(cao)整體(ti)(ti)式(shi)。棉繩（化(hua)學(xue)纖維(wei)）手工(gong)(gong)編織橡(xiang)膠軟管因應用(yong)工(gong)(gong)作壓力低，拔脫力小，都選用(yong)無槽(cao)(cao)體(ti)(ti)式(shi)構造。不銹鋼(gang)絲手工(gong)(gong)編織橡(xiang)膠軟管在壓扣(kou)時其(qi)(qi)提(ti)高(gao)(gao)層(ceng)(ceng)易(yi)造成彎折形變(bian)，多(duo)(duo)選用(yong)鋸(ju)齒(chi)(chi)狀。不銹鋼(gang)絲螺(luo)旋波(bo)紋管一般疊(die)加層(ceng)(ceng)數較多(duo)(duo)，提(ti)高(gao)(gao)層(ceng)(ceng)的單側(ce)薄厚較大 達到(dao)３.６ｍｍ，壓扣(kou)時要使(shi)提(ti)高(gao)(gao)層(ceng)(ceng)產(chan)生波(bo)浪(lang)狀形變(bian)而(er)置入(ru)槽(cao)(cao)體(ti)(ti)就(jiu)務必選用(yong)環狀和(he)鋸(ju)齒(chi)(chi)狀槽(cao)(cao)相組成，這類槽(cao)(cao)形比鋸(ju)齒(chi)(chi)狀槽(cao)(cao)寬２／３，其(qi)(qi)抗(kang)拔脫力更強。
