軟管總成壓扣工(gong)藝流(liu)程是危(wei)害品質的關鍵要素

危害壓扣式橡膠軟管接頭總成(cheng)(cheng)品質的關鍵加工(gong)工(gong)藝要素是(shi)壓(ya)扣工(gong)藝流(liu)程(cheng)。現(xian)階段關鍵有(you)二種壓(ya)扣方法，一種是(shi)軸(zhou)徑送入式(shi)，可(ke)在通用(yong)性壓(ya)機里(li)用(yong)專(zhuan)用(yong)型模貝來完成(cheng)(cheng)。其壓(ya)扣量(liang)不(bu)容易(yi)調節(jie)，在壓(ya)扣全(quan)過程(cheng)中非常容易(yi)損(sun)害外衣外表層。為了更好(hao)地取下壓(ya)扣件。務必把模貝制(zhi)成(cheng)(cheng)對開(kai)(kai)啟式(shi)。這就會有(you)合縫，使制(zhi)成(cheng)(cheng)品外型不(bu)太好(hao)。另一種為軸(zhou)向壓(ya)扣式(shi)其模貝有(you)兩開(kai)(kai)、三瓣、六瓣和八瓣模之(zhi)分。合適大批量(liang)生(sheng)產(chan)一般用(yong)六瓣和八瓣模貝，確(que)保壓(ya)扣品質的基(ji)本是(shi)恰當把握橡膠軟(ruan)管(guan)的內膠縮小(xiao)量(liang)和外衣的壓(ya)扣量(liang)。

其(qi)中孔(kong)規(gui)格盡可(ke)能超過提高層(ceng)規(gui)格，不(bu)(bu)然沒法裝進，乃至會(hui)導(dao)致提高層(ceng)完全(quan)散頭狀(zhuang)況。一般(ban)空(kong)隙為１～１.５ｍｍ。外(wai)衣(yi)內部(bu)的槽(cao)(cao)(cao)形(xing)(xing)會(hui)立即危(wei)害接頭品質。現階段有直(zhi)孔(kong)無(wu)槽(cao)(cao)(cao)體(ti)式(shi)、鋸齒(chi)(chi)(chi)狀(zhuang)槽(cao)(cao)(cao)體(ti)式(shi)及(ji)其(qi)環狀(zhuang)和(he)鋸齒(chi)(chi)(chi)狀(zhuang)槽(cao)(cao)(cao)整(zheng)體(ti)式(shi)。棉繩（化學纖維）手(shou)工(gong)編織橡膠軟(ruan)管因應用(yong)(yong)工(gong)作(zuo)壓(ya)力(li)低，拔脫力(li)小(xiao)，都選(xuan)(xuan)用(yong)(yong)無(wu)槽(cao)(cao)(cao)體(ti)式(shi)構造(zao)。不(bu)(bu)銹鋼(gang)絲手(shou)工(gong)編織橡膠軟(ruan)管在(zai)壓(ya)扣時(shi)其(qi)提高層(ceng)易(yi)造(zao)成彎折形(xing)(xing)變，多選(xuan)(xuan)用(yong)(yong)鋸齒(chi)(chi)(chi)狀(zhuang)。不(bu)(bu)銹鋼(gang)絲螺旋(xuan)波紋管一般(ban)疊加(jia)層(ceng)數較多，提高層(ceng)的單側(ce)薄(bo)厚較大(da) 達到３.６ｍｍ，壓(ya)扣時(shi)要(yao)使提高層(ceng)產生波浪(lang)狀(zhuang)形(xing)(xing)變而(er)置(zhi)入(ru)槽(cao)(cao)(cao)體(ti)就務必選(xuan)(xuan)用(yong)(yong)環狀(zhuang)和(he)鋸齒(chi)(chi)(chi)狀(zhuang)槽(cao)(cao)(cao)相組(zu)成，這類槽(cao)(cao)(cao)形(xing)(xing)比鋸齒(chi)(chi)(chi)狀(zhuang)槽(cao)(cao)(cao)寬２／３，其(qi)抗(kang)拔脫力(li)更(geng)強。
