軟管總成壓(ya)扣(kou)工藝流程是危害品質的關鍵要素

危害壓扣式橡膠軟管接頭總成品(pin)質的(de)關鍵加工工藝要素(su)是壓(ya)(ya)扣(kou)工藝流程(cheng)(cheng)。現階段(duan)關鍵有二(er)種(zhong)壓(ya)(ya)扣(kou)方法(fa)，一(yi)種(zhong)是軸(zhou)徑送(song)入式，可在通用(yong)(yong)性壓(ya)(ya)機(ji)里用(yong)(yong)專用(yong)(yong)型模貝來完成。其(qi)壓(ya)(ya)扣(kou)量不容(rong)(rong)易(yi)調節(jie)，在壓(ya)(ya)扣(kou)全過程(cheng)(cheng)中非常容(rong)(rong)易(yi)損(sun)害外(wai)衣(yi)外(wai)表(biao)層。為了更好(hao)地取下壓(ya)(ya)扣(kou)件。務(wu)必(bi)把(ba)模貝制成對(dui)開啟式。這就會有合縫，使制成品(pin)外(wai)型不太好(hao)。另(ling)一(yi)種(zhong)為軸(zhou)向壓(ya)(ya)扣(kou)式其(qi)模貝有兩開、三瓣(ban)、六瓣(ban)和(he)八(ba)瓣(ban)模之(zhi)分。合適(shi)大批量生產一(yi)般用(yong)(yong)六瓣(ban)和(he)八(ba)瓣(ban)模貝，確(que)保壓(ya)(ya)扣(kou)品(pin)質的(de)基本(ben)是恰當把(ba)握(wo)橡膠軟管的(de)內膠縮小量和(he)外(wai)衣(yi)的(de)壓(ya)(ya)扣(kou)量。

其(qi)(qi)中孔(kong)規(gui)格(ge)盡(jin)可能超過提高(gao)層規(gui)格(ge)，不然(ran)沒法裝進，乃(nai)至(zhi)會導致提高(gao)層完(wan)全(quan)散頭(tou)狀(zhuang)(zhuang)況。一(yi)般空隙為１～１.５ｍｍ。外衣(yi)內部的槽形(xing)(xing)(xing)會立即(ji)危害(hai)接頭(tou)品質。現階段有直孔(kong)無槽體式(shi)、鋸齒(chi)狀(zhuang)(zhuang)槽體式(shi)及其(qi)(qi)環狀(zhuang)(zhuang)和鋸齒(chi)狀(zhuang)(zhuang)槽整(zheng)體式(shi)。棉繩（化學纖維(wei)）手工編織橡膠(jiao)軟管因應用(yong)工作壓(ya)力低(di)，拔脫(tuo)力小，都選(xuan)(xuan)用(yong)無槽體式(shi)構造(zao)(zao)。不銹鋼絲手工編織橡膠(jiao)軟管在壓(ya)扣時其(qi)(qi)提高(gao)層易造(zao)(zao)成彎折形(xing)(xing)(xing)變(bian)，多選(xuan)(xuan)用(yong)鋸齒(chi)狀(zhuang)(zhuang)。不銹鋼絲螺旋波紋管一(yi)般疊加(jia)層數(shu)較多，提高(gao)層的單側薄厚較大 達到３.６ｍｍ，壓(ya)扣時要使(shi)提高(gao)層產生(sheng)波浪狀(zhuang)(zhuang)形(xing)(xing)(xing)變(bian)而置入(ru)槽體就務必選(xuan)(xuan)用(yong)環狀(zhuang)(zhuang)和鋸齒(chi)狀(zhuang)(zhuang)槽相組成，這類(lei)槽形(xing)(xing)(xing)比鋸齒(chi)狀(zhuang)(zhuang)槽寬２／３，其(qi)(qi)抗拔脫(tuo)力更(geng)強。
