金屬波紋膨脹節用金屬波紋管的成形決定著膨脹節的整個制造工藝流程,是金屬波紋膨脹節制造的核心,在此介紹三種成形工藝:機械脹形工藝、滾壓成形工藝和橡膠成形工藝三種。膨脹節廠家
1.金屬波紋膨脹節的機械脹形工藝
機(ji)(ji)械脹(zhang)(zhang)(zhang)(zhang)(zhang)形(xing)(xing)工藝是制造(zao)金(jin)屬(shu)波(bo)紋(wen)(wen)膨(peng)脹(zhang)(zhang)(zhang)(zhang)(zhang)節用(yong)金(jin)屬(shu)波(bo)紋(wen)(wen)管的(de)(de)(de)主要方法之(zhi)一(yi)(yi),美國金(jin)屬(shu)波(bo)紋(wen)(wen)膨(peng)脹(zhang)(zhang)(zhang)(zhang)(zhang)節公司多應(ying)用(yong)機(ji)(ji)械脹(zhang)(zhang)(zhang)(zhang)(zhang)形(xing)(xing)工藝成(cheng)(cheng)形(xing)(xing)金(jin)屬(shu)波(bo)紋(wen)(wen)管。機(ji)(ji)械脹(zhang)(zhang)(zhang)(zhang)(zhang)形(xing)(xing)工藝過程(cheng)如(ru)下:將(jiang)極(ji)薄(bo)(bo)壁(bi)管材(cai)(cai)套進脹(zhang)(zhang)(zhang)(zhang)(zhang)形(xing)(xing)模(mo)(mo)(mo),在(zai)(zai)液壓機(ji)(ji)或(huo)其他(ta)裝置的(de)(de)(de)軸(zhou)向(xiang)壓力作(zuo)用(yong)下,楔狀芯軸(zhou)沿型芯向(xiang)下或(huo)向(xiang)上(shang)運動(dong),進而(er)將(jiang)剛(gang)體分(fen)(fen)瓣(ban)凹模(mo)(mo)(mo)向(xiang)外擴張,使得極(ji)薄(bo)(bo)壁(bi)管材(cai)(cai)產(chan)生脹(zhang)(zhang)(zhang)(zhang)(zhang)形(xing)(xing)變形(xing)(xing),當脹(zhang)(zhang)(zhang)(zhang)(zhang)形(xing)(xing)結束后,分(fen)(fen)瓣(ban)凸(tu)模(mo)(mo)(mo)和楔狀芯軸(zhou)在(zai)(zai)退模(mo)(mo)(mo)力的(de)(de)(de)作(zuo)用(yong)下回復到原始位置。脹(zhang)(zhang)(zhang)(zhang)(zhang)形(xing)(xing)后的(de)(de)(de)工件軸(zhou)向(xiang)移(yi)動(dong)一(yi)(yi)段(duan)距離(li),以(yi)(yi)便(bian)脹(zhang)(zhang)(zhang)(zhang)(zhang)形(xing)(xing)下一(yi)(yi)個(ge)波(bo),機(ji)(ji)械脹(zhang)(zhang)(zhang)(zhang)(zhang)形(xing)(xing)每(mei)次(ci)(ci)成(cheng)(cheng)形(xing)(xing)一(yi)(yi)個(ge)波(bo),屬(shu)于(yu)單(dan)波(bo)逐次(ci)(ci)成(cheng)(cheng)形(xing)(xing)。成(cheng)(cheng)形(xing)(xing)第二個(ge)波(bo)紋(wen)(wen)時(shi),以(yi)(yi)第一(yi)(yi)次(ci)(ci)成(cheng)(cheng)形(xing)(xing)的(de)(de)(de)波(bo)紋(wen)(wen)定位,以(yi)(yi)此逐次(ci)(ci)成(cheng)(cheng)形(xing)(xing)。脹(zhang)(zhang)(zhang)(zhang)(zhang)形(xing)(xing)時(shi)圓(yuan)筒部分(fen)(fen)隨著脹(zhang)(zhang)(zhang)(zhang)(zhang)形(xing)(xing)的(de)(de)(de)變形(xing)(xing)力自由地(di)拉入,以(yi)(yi)減少脹(zhang)(zhang)(zhang)(zhang)(zhang)形(xing)(xing)部分(fen)(fen)的(de)(de)(de)減薄(bo)(bo)量。按圓(yuan)筒脹(zhang)(zhang)(zhang)(zhang)(zhang)形(xing)(xing)分(fen)(fen)類,它屬(shu)于(yu)自然脹(zhang)(zhang)(zhang)(zhang)(zhang)形(xing)(xing),在(zai)(zai)脹(zhang)(zhang)(zhang)(zhang)(zhang)形(xing)(xing)過程(cheng)沒有(you)(you)加(jia)軸(zhou)向(xiang)力。機(ji)(ji)械脹(zhang)(zhang)(zhang)(zhang)(zhang)形(xing)(xing)屬(shu)于(yu)單(dan)模(mo)(mo)(mo)具成(cheng)(cheng)形(xing)(xing),一(yi)(yi)般情況下它只有(you)(you)凸(tu)模(mo)(mo)(mo),應(ying)用(yong)機(ji)(ji)械脹(zhang)(zhang)(zhang)(zhang)(zhang)形(xing)(xing)實現波(bo)紋(wen)(wen)管的(de)(de)(de)成(cheng)(cheng)形(xing)(xing),其凸(tu)模(mo)(mo)(mo)的(de)(de)(de)分(fen)(fen)瓣(ban)的(de)(de)(de)分(fen)(fen)瓣(ban)越多,則脹(zhang)(zhang)(zhang)(zhang)(zhang)形(xing)(xing)精度就越高(gao),如(ru)果(guo)在(zai)(zai)結構上(shang)加(jia)以(yi)(yi)改(gai)進,可以(yi)(yi)進一(yi)(yi)步消(xiao)除脹(zhang)(zhang)(zhang)(zhang)(zhang)形(xing)(xing)時(shi)出現的(de)(de)(de)各(ge)分(fen)(fen)瓣(ban)凸(tu)模(mo)(mo)(mo)之(zhi)間分(fen)(fen)瓣(ban)痕跡。
2.金(jin)屬波紋膨脹節(jie)滾壓成形工藝
滾壓(ya)(ya)成形(xing)(xing)工(gong)藝主要用來成形(xing)(xing)金屬波紋(wen)膨脹(zhang)節(jie)用的(de)金屬波紋(wen)管(guan),適合大(da)直徑波紋(wen)管(guan)的(de)成形(xing)(xing)。滾壓(ya)(ya)成形(xing)(xing)的(de)原材(cai)料形(xing)(xing)式為極(ji)薄(bo)壁(bi)管(guan)材(cai)或機械脹(zhang)形(xing)(xing)之后(hou)的(de)波紋(wen)管(guan),后(hou)者主要用于(yu)精密校(xiao)形(xing)(xing)。滾壓(ya)(ya)成形(xing)(xing)過程將薄(bo)壁(bi)管(guan)置于(yu)滾壓(ya)(ya)成形(xing)(xing)機中,滾壓(ya)(ya)時(shi)隨(sui)著波形(xing)(xing)的(de)加深,動(dong)輥(gun)要作徑向進給,同時(shi)各輥(gun)上的(de)滾輪要作響應(ying)的(de)軸(zhou)向移(yi)動(dong)。滾壓(ya)(ya)逐個成形(xing)(xing)需要進行(xing)多次滾壓(ya)(ya)。
3.金屬(shu)波紋(wen)膨脹節(jie)橡膠成形工藝
橡(xiang)膠(jiao)(jiao)成(cheng)(cheng)(cheng)形(xing)(xing)工藝成(cheng)(cheng)(cheng)形(xing)(xing)方(fang)式為單(dan)波連續成(cheng)(cheng)(cheng)形(xing)(xing),屬(shu)于軟(ruan)模(mo)(mo)(mo)成(cheng)(cheng)(cheng)形(xing)(xing)方(fang)法的(de)(de)一種(zhong)。以(yi)(yi)橡(xiang)膠(jiao)(jiao)為軟(ruan)模(mo)(mo)(mo),以(yi)(yi)成(cheng)(cheng)(cheng)形(xing)(xing)凹(ao)模(mo)(mo)(mo)為硬模(mo)(mo)(mo),橡(xiang)膠(jiao)(jiao)脹形(xing)(xing)時,軸向壓(ya)縮(suo)橡(xiang)膠(jiao)(jiao),管材隨著橡(xiang)膠(jiao)(jiao)的(de)(de)壓(ya)縮(suo)進行(xing)脹形(xing)(xing),卸去壓(ya)縮(suo)橡(xiang)膠(jiao)(jiao)的(de)(de)軸向力(li),橡(xiang)膠(jiao)(jiao)在自身彈力(li)的(de)(de)作用(yong)下回(hui)復到(dao)原始狀(zhuang)態,然后(hou)有專(zhuan)用(yong)裝置推動(dong)可軸向移動(dong)的(de)(de)成(cheng)(cheng)(cheng)形(xing)(xing)凹(ao)模(mo)(mo)(mo)進行(xing)軸向運(yun)動(dong),壓(ya)縮(suo)已經進行(xing)脹形(xing)(xing)的(de)(de)波紋管,直到(dao)兩個(ge)凹(ao)模(mo)(mo)(mo)軸向貼合(he)。
