液壓(ya)成(cheng)形是金屬鋼波紋涵管應(ying)用(yong)常見的(de)一(yi)種(zhong)成(cheng)(cheng)形方法。主要(yao)用(yong)來(lai)制造環形波紋(wen)(wen)(wen)涵(han)(han)(han)管(guan)(guan)，可成(cheng)(cheng)形壁(bi)厚(hou)0.08-4mm的(de)波紋(wen)(wen)(wen)涵(han)(han)(han)管(guan)(guan)。波紋(wen)(wen)(wen)涵(han)(han)(han)管(guan)(guan)液壓成(cheng)(cheng)形是管(guan)(guan)坯在(zai)受內(nei)壁(bi)液體壓力下(xia)，當應(ying)力超過屈服強度后，在(zai)專用(yong)模其內(nei)成(cheng)(cheng)形為波紋(wen)(wen)(wen)涵(han)(han)(han)管(guan)(guan)。金屬波紋(wen)(wen)(wen)涵(han)(han)(han)管(guan)(guan)2.機(ji)(ji)械(xie)成(cheng)(cheng)形工藝(yi)波紋(wen)(wen)(wen)涵(han)(han)(han)管(guan)(guan)的(de)機(ji)(ji)械(xie)成(cheng)(cheng)形，包括旋1-I成(cheng)(cheng)形、滾仄(ze)成(cheng)(cheng)形和機(ji)(ji)械(xie)膨脹等(deng)工藝(yi)方法。

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)運輸(shu)狀(zhuang)況(kuang)，橋(qiao)梁的(de)(de)(de)承載能(neng)力和(he)通過(guo)的(de)(de)(de)車輛不成正比。舊(jiu)橋(qiao)加固(gu)工程迫在眉睫，為(wei)了提高舊(jiu)橋(qiao)的(de)(de)(de)承載能(neng)力，確(que)保交通運輸(shu)的(de)(de)(de)安全是目前和(he)今后面(mian)臨的(de)(de)(de)任務。今天小編給大(da)家介紹一款舊(jiu)橋(qiao)加固(gu)的(de)(de)(de)好產品(pin)---鋼(gang)波紋涵管。

鐵路鋼波(bo)紋管

機械液(ye)壓成形的(de)波(bo)紋涵(han)管，由于波(bo)峰、波(bo)谷(gu)都參加了變形，都達到(dao)了強化，對提高(gao)波(bo)紋涵(han)管彈性起到(dao)了良好的(de)作(zuo)用，是制造深(shen)波(bo)波(bo)紋涵(han)管的(de)一種有(you)效工藝方法。隨著經濟的(de)發展和(he)重(zhong)點(dian)工程(cheng)的(de)建設，目(mu)前公(gong)路(lu)橋(qiao)梁(liang)所承受(shou)的(de)負荷有(you)3個(ge)特點(dian)：1、交通量不斷增(zeng)大。2、重(zhong)型車輛增(zeng)加及(ji)超(chao)載現(xian)象(xiang)嚴(yan)重(zhong)。3、超(chao)限(xian)運輸的(de)出現(xian)和(he)增(zeng)加。

它是以橡膠為成(cheng)(cheng)(cheng)(cheng)形凸模，在壓(ya)力作用下像膠凸模變(bian)形，把管(guan)(guan)坯按凹模型腔成(cheng)(cheng)(cheng)(cheng)形波(bo)紋涵(han)(han)管(guan)(guan)，成(cheng)(cheng)(cheng)(cheng)形方(fang)(fang)式(shi)通常是單波(bo)連續成(cheng)(cheng)(cheng)(cheng)形。金屬波(bo)紋涵(han)(han)管(guan)(guan)4.機(ji)械(xie)液1-I;成(cheng)(cheng)(cheng)(cheng)形機(ji)械(xie)液壓(ya)成(cheng)(cheng)(cheng)(cheng)形是將管(guan)(guan)幼:先用滾壓(ya)方(fang)(fang)法(fa)向內滾形，然后用液壓(ya)方(fang)(fang)法(fa)向外脹形形成(cheng)(cheng)(cheng)(cheng)波(bo)紋涵(han)(han)管(guan)(guan)的成(cheng)(cheng)(cheng)(cheng)形方(fang)(fang)法(fa)。

一(yi)般(ban)來說機械(xie)成形其有工(gong)(gong)藝(yi)簡單、工(gong)(gong)裝制(zhi)造(zao)容易，生產(chan)效率高(gao)等優點。同(tong)時也存在產(chan)品制(zhi)造(zao)比較(jiao)粗糙，性能不高(gao)等缺點.它較(jiao)多(duo)應用于螺旋波紋(wen)(wen)涵管(guan)，波紋(wen)(wen)膨脹節(jie)、大直徑厚壁(bi)波紋(wen)(wen)涵管(guan)的制(zhi)造(zao)。金屬(shu)波紋(wen)(wen)涵管(guan)3.橡膠(jiao)成形工(gong)(gong)藝(yi)橡膠(jiao)成形工(gong)(gong)藝(yi)是(shi)脹形工(gong)(gong)藝(yi)的一(yi)種。

鋼制波紋管涵

波(bo)紋(wen)涵(han)管的波(bo)紋(wen)成(cheng)(cheng)(cheng)形(xing)(xing)是(shi)制(zhi)造(zao)波(bo)紋(wen)涵(han)管的關鍵工(gong)(gong)藝(yi)。日前(qian)常用(yong)的成(cheng)(cheng)(cheng)形(xing)(xing)方法有(you):液(ye)壓成(cheng)(cheng)(cheng)形(xing)(xing)、機(ji)械成(cheng)(cheng)(cheng)形(xing)(xing)、橡(xiang)膠成(cheng)(cheng)(cheng)形(xing)(xing)、焊接成(cheng)(cheng)(cheng)形(xing)(xing)、電化學成(cheng)(cheng)(cheng)形(xing)(xing)等。液(ye)壓成(cheng)(cheng)(cheng)形(xing)(xing)和(he)機(ji)械成(cheng)(cheng)(cheng)形(xing)(xing)是(shi)金(jin)(jin)(jin)屬波(bo)紋(wen)涵(han)管制(zhi)造(zao)行業(ye)常用(yong)的工(gong)(gong)藝(yi)。它(ta)適于制(zhi)造(zao)其(qi)有(you)良(liang)好(hao)塑性(xing)的銅合金(jin)(jin)(jin)、不銹鋼、彈性(xing)合金(jin)(jin)(jin)及(ji)高溫合金(jin)(jin)(jin)等材(cai)料的U型(xing)、S型(xing)等波(bo)型(xing)的波(bo)紋(wen)涵(han)管，其(qi)有(you)的適應性(xing)和(he)良(liang)好(hao)的工(gong)(gong)藝(yi)性(xing)。

鋼波紋(wen)涵管(guan)具(ju)有(you)重(zhong)量輕，施工簡單、工期短等(deng)優點，波紋(wen)管(guan)底部及兩(liang)側可填充沙礫、碎(sui)石(shi)土、片石(shi)砼(tong)等(deng)材料，鋼波紋(wen)涵管(guan)頂部可用(yong)高壓泵送(song)膨(peng)脹水泥沙漿(jiang)或砌筑片石(shi)膨(peng)脹砼(tong)，此方法在舊(jiu)橋加固(gu)工程中取得了很好(hao)的效果。（hanihanbj.com）
