液壓成形是金屬鋼波紋涵管應(ying)用常見的(de)一種成(cheng)(cheng)(cheng)形(xing)(xing)方法(fa)(fa)。主(zhu)要用來制(zhi)造環(huan)形(xing)(xing)波(bo)紋涵(han)管,可成(cheng)(cheng)(cheng)形(xing)(xing)壁(bi)厚0.08-4mm的(de)波(bo)紋涵(han)管。波(bo)紋涵(han)管液(ye)壓(ya)成(cheng)(cheng)(cheng)形(xing)(xing)是管坯在受內壁(bi)液(ye)體壓(ya)力下,當應(ying)力超過屈服強(qiang)度后,在專用模其內成(cheng)(cheng)(cheng)形(xing)(xing)為波(bo)紋涵(han)管。金屬波(bo)紋涵(han)管2.機械(xie)成(cheng)(cheng)(cheng)形(xing)(xing)工(gong)(gong)藝波(bo)紋涵(han)管的(de)機械(xie)成(cheng)(cheng)(cheng)形(xing)(xing),包(bao)括旋1-I成(cheng)(cheng)(cheng)形(xing)(xing)、滾仄成(cheng)(cheng)(cheng)形(xing)(xing)和機械(xie)膨脹(zhang)等工(gong)(gong)藝方法(fa)(fa)。

為什么說要加強鋼波紋涵管的承載能力迫在眉睫?

按現在橋(qiao)梁和(he)(he)運輸狀況(kuang),橋(qiao)梁的(de)承載(zai)能力(li)和(he)(he)通過的(de)車輛不(bu)成正(zheng)比。舊(jiu)(jiu)橋(qiao)加固(gu)工程迫在眉睫,為(wei)了提高舊(jiu)(jiu)橋(qiao)的(de)承載(zai)能力(li),確保交(jiao)通運輸的(de)安全是目前和(he)(he)今后面(mian)臨的(de)任(ren)務。今天小編給大(da)家介紹一款舊(jiu)(jiu)橋(qiao)加固(gu)的(de)好產品---鋼波紋涵管。

鐵路鋼波紋管

鐵路(lu)鋼波紋管(guan)

機械(xie)液壓成形的波(bo)紋(wen)涵管(guan),由于波(bo)峰、波(bo)谷都參加了變形,都達到(dao)了強(qiang)化,對提高(gao)波(bo)紋(wen)涵管(guan)彈性(xing)起到(dao)了良好的作用(yong),是制造(zao)深波(bo)波(bo)紋(wen)涵管(guan)的一種有(you)效工藝方法。隨(sui)著經濟的發(fa)展和(he)(he)重點工程的建設,目(mu)前公路橋(qiao)梁所(suo)承受的負荷有(you)3個特點:1、交(jiao)通(tong)量不斷增大(da)。2、重型車(che)輛增加及超(chao)載現象嚴重。3、超(chao)限運輸的出現和(he)(he)增加。

它是(shi)(shi)以橡膠為成(cheng)(cheng)形(xing)(xing)(xing)(xing)凸模,在壓力作用下像膠凸模變形(xing)(xing)(xing)(xing),把管(guan)坯按凹模型腔成(cheng)(cheng)形(xing)(xing)(xing)(xing)波紋涵(han)管(guan),成(cheng)(cheng)形(xing)(xing)(xing)(xing)方(fang)式通常是(shi)(shi)單波連續成(cheng)(cheng)形(xing)(xing)(xing)(xing)。金(jin)屬波紋涵(han)管(guan)4.機(ji)械(xie)液1-I;成(cheng)(cheng)形(xing)(xing)(xing)(xing)機(ji)械(xie)液壓成(cheng)(cheng)形(xing)(xing)(xing)(xing)是(shi)(shi)將(jiang)管(guan)幼:先用滾壓方(fang)法向(xiang)內(nei)滾形(xing)(xing)(xing)(xing),然后用液壓方(fang)法向(xiang)外脹(zhang)形(xing)(xing)(xing)(xing)形(xing)(xing)(xing)(xing)成(cheng)(cheng)波紋涵(han)管(guan)的成(cheng)(cheng)形(xing)(xing)(xing)(xing)方(fang)法。

一般來說機械(xie)成形其有工藝(yi)簡單、工裝制(zhi)造(zao)容易(yi),生產(chan)效率高(gao)等(deng)優點(dian)(dian)。同時也存在產(chan)品(pin)制(zhi)造(zao)比(bi)較粗糙(cao),性能不(bu)高(gao)等(deng)缺點(dian)(dian).它較多應(ying)用于螺(luo)旋(xuan)波(bo)紋(wen)(wen)涵(han)管(guan)(guan)(guan),波(bo)紋(wen)(wen)膨脹節、大直(zhi)徑厚壁波(bo)紋(wen)(wen)涵(han)管(guan)(guan)(guan)的制(zhi)造(zao)。金屬(shu)波(bo)紋(wen)(wen)涵(han)管(guan)(guan)(guan)3.橡膠成形工藝(yi)橡膠成形工藝(yi)是脹形工藝(yi)的一種。

鋼制波紋管涵

波紋(wen)涵(han)(han)管的(de)波紋(wen)成(cheng)形(xing)(xing)是制(zhi)造波紋(wen)涵(han)(han)管的(de)關鍵(jian)工(gong)(gong)藝(yi)。日前常用(yong)的(de)成(cheng)形(xing)(xing)方法有:液(ye)(ye)壓(ya)(ya)成(cheng)形(xing)(xing)、機械(xie)成(cheng)形(xing)(xing)、橡膠成(cheng)形(xing)(xing)、焊接(jie)成(cheng)形(xing)(xing)、電化學成(cheng)形(xing)(xing)等(deng)(deng)(deng)。液(ye)(ye)壓(ya)(ya)成(cheng)形(xing)(xing)和機械(xie)成(cheng)形(xing)(xing)是金(jin)屬波紋(wen)涵(han)(han)管制(zhi)造行業(ye)常用(yong)的(de)工(gong)(gong)藝(yi)。它適于制(zhi)造其有良(liang)(liang)好塑性的(de)銅合金(jin)、不銹鋼、彈(dan)性合金(jin)及高溫合金(jin)等(deng)(deng)(deng)材料的(de)U型、S型等(deng)(deng)(deng)波型的(de)波紋(wen)涵(han)(han)管,其有的(de)適應(ying)性和良(liang)(liang)好的(de)工(gong)(gong)藝(yi)性。

鋼波紋涵管具(ju)有重量輕,施(shi)工(gong)簡單、工(gong)期短等優點(dian),波紋管底部及兩側可填充沙(sha)(sha)礫(li)、碎石(shi)土、片(pian)石(shi)砼等材料,鋼波紋涵管頂部可用高壓(ya)泵送膨(peng)(peng)脹(zhang)水泥沙(sha)(sha)漿(jiang)或砌筑片(pian)石(shi)膨(peng)(peng)脹(zhang)砼,此方法在舊橋加固工(gong)程(cheng)中取(qu)得了很好的效果。(hanihanbj.com
