軟管總成壓扣工藝流程是危害品質(zhi)的關(guan)鍵(jian)要(yao)素

危害壓扣式橡膠軟管接頭總成(cheng)品質(zhi)的關鍵(jian)加工(gong)工(gong)藝(yi)要素是壓(ya)(ya)扣工(gong)藝(yi)流程。現階段關鍵(jian)有(you)二種(zhong)(zhong)壓(ya)(ya)扣方法(fa)，一種(zhong)(zhong)是軸(zhou)徑(jing)送入式，可在通(tong)用(yong)(yong)性(xing)壓(ya)(ya)機里用(yong)(yong)專用(yong)(yong)型(xing)模(mo)貝(bei)來(lai)完成(cheng)。其壓(ya)(ya)扣量不(bu)容易(yi)調(diao)節，在壓(ya)(ya)扣全過(guo)程中非常容易(yi)損害(hai)外衣外表層。為了(le)更好地(di)取下壓(ya)(ya)扣件。務必把模(mo)貝(bei)制(zhi)成(cheng)對開啟式。這就(jiu)會有(you)合縫，使(shi)制(zhi)成(cheng)品外型(xing)不(bu)太(tai)好。另一種(zhong)(zhong)為軸(zhou)向壓(ya)(ya)扣式其模(mo)貝(bei)有(you)兩開、三瓣(ban)、六瓣(ban)和八瓣(ban)模(mo)之分。合適(shi)大批量生產一般用(yong)(yong)六瓣(ban)和八瓣(ban)模(mo)貝(bei)，確(que)保壓(ya)(ya)扣品質(zhi)的基本是恰當把握橡膠軟管的內膠縮小量和外衣的壓(ya)(ya)扣量。

其(qi)中孔規格盡可能(neng)超過(guo)提(ti)(ti)高(gao)層(ceng)(ceng)規格，不然(ran)沒法裝(zhuang)進，乃至(zhi)會導致提(ti)(ti)高(gao)層(ceng)(ceng)完全散頭狀況。一(yi)般空隙為１～１.５ｍｍ。外衣(yi)內部的(de)槽(cao)形會立即危害接頭品質。現階段有直孔無槽(cao)體(ti)式(shi)、鋸齒(chi)狀槽(cao)體(ti)式(shi)及其(qi)環狀和(he)鋸齒(chi)狀槽(cao)整(zheng)體(ti)式(shi)。棉繩（化學纖維）手工編織橡(xiang)膠軟(ruan)管因應用(yong)(yong)工作壓力低，拔(ba)脫力小，都選用(yong)(yong)無槽(cao)體(ti)式(shi)構造。不銹鋼絲(si)手工編織橡(xiang)膠軟(ruan)管在壓扣(kou)時其(qi)提(ti)(ti)高(gao)層(ceng)(ceng)易造成彎折形變，多(duo)選用(yong)(yong)鋸齒(chi)狀。不銹鋼絲(si)螺旋波紋管一(yi)般疊(die)加層(ceng)(ceng)數較多(duo)，提(ti)(ti)高(gao)層(ceng)(ceng)的(de)單(dan)側薄厚較大 達到３.６ｍｍ，壓扣(kou)時要使(shi)提(ti)(ti)高(gao)層(ceng)(ceng)產(chan)生波浪狀形變而置入槽(cao)體(ti)就務必(bi)選用(yong)(yong)環狀和(he)鋸齒(chi)狀槽(cao)相組(zu)成，這類槽(cao)形比鋸齒(chi)狀槽(cao)寬２／３，其(qi)抗拔(ba)脫力更強(qiang)。
