軟管總成壓扣(kou)工藝流(liu)程是危害品質的關鍵要(yao)素

危害壓扣式橡膠軟管接頭總(zong)成(cheng)(cheng)品(pin)(pin)質(zhi)的(de)關鍵加工(gong)工(gong)藝(yi)要素是壓(ya)(ya)扣工(gong)藝(yi)流程。現階段關鍵有二種(zhong)壓(ya)(ya)扣方(fang)法，一(yi)種(zhong)是軸徑送入(ru)式(shi)，可在通用性壓(ya)(ya)機里用專用型模貝來完成(cheng)(cheng)。其壓(ya)(ya)扣量不容易調節，在壓(ya)(ya)扣全(quan)過程中非常容易損害外(wai)衣(yi)外(wai)表層。為了更好地取下(xia)壓(ya)(ya)扣件。務(wu)必把(ba)模貝制(zhi)成(cheng)(cheng)對開啟(qi)式(shi)。這(zhe)就會有合(he)縫，使制(zhi)成(cheng)(cheng)品(pin)(pin)外(wai)型不太好。另(ling)一(yi)種(zhong)為軸向(xiang)壓(ya)(ya)扣式(shi)其模貝有兩開、三瓣(ban)、六(liu)瓣(ban)和八瓣(ban)模之分。合(he)適(shi)大批量生產一(yi)般用六(liu)瓣(ban)和八瓣(ban)模貝，確保壓(ya)(ya)扣品(pin)(pin)質(zhi)的(de)基本是恰(qia)當把(ba)握橡(xiang)膠軟管的(de)內膠縮小(xiao)量和外(wai)衣(yi)的(de)壓(ya)(ya)扣量。

其(qi)(qi)中孔規格盡(jin)可(ke)能(neng)超過提高(gao)層(ceng)規格，不(bu)然沒(mei)法裝進(jin)，乃至(zhi)會導致(zhi)提高(gao)層(ceng)完全散(san)頭狀況(kuang)。一般(ban)空隙(xi)為(wei)１～１.５ｍｍ。外衣內部的槽形會立即危害接(jie)頭品(pin)質。現(xian)階段有直(zhi)孔無(wu)槽體(ti)式(shi)、鋸齒(chi)(chi)狀槽體(ti)式(shi)及(ji)其(qi)(qi)環狀和(he)鋸齒(chi)(chi)狀槽整體(ti)式(shi)。棉繩（化學纖維）手工編(bian)織橡(xiang)膠軟(ruan)管因應用(yong)(yong)(yong)工作壓(ya)力低，拔(ba)(ba)脫(tuo)力小(xiao)，都選用(yong)(yong)(yong)無(wu)槽體(ti)式(shi)構造。不(bu)銹(xiu)鋼絲(si)手工編(bian)織橡(xiang)膠軟(ruan)管在壓(ya)扣時(shi)其(qi)(qi)提高(gao)層(ceng)易造成彎折形變，多(duo)選用(yong)(yong)(yong)鋸齒(chi)(chi)狀。不(bu)銹(xiu)鋼絲(si)螺(luo)旋(xuan)波(bo)紋管一般(ban)疊加層(ceng)數較多(duo)，提高(gao)層(ceng)的單側(ce)薄厚較大 達到３.６ｍｍ，壓(ya)扣時(shi)要使提高(gao)層(ceng)產生波(bo)浪狀形變而置入槽體(ti)就務必選用(yong)(yong)(yong)環狀和(he)鋸齒(chi)(chi)狀槽相(xiang)組成，這類槽形比鋸齒(chi)(chi)狀槽寬２／３，其(qi)(qi)抗(kang)拔(ba)(ba)脫(tuo)力更強。
