彎管機(ji)(ji)出(chu)口商品結構(gou)無明(ming)顯好轉，金(jin)屬(shu)(shu)加工機(ji)(ji)床(chuang)出(chu)口呈直線上(shang)升趨勢，數(shu)(shu)控(kong)金(jin)屬(shu)(shu)加工機(ji)(ji)床(chuang)增(zeng)長66%以上(shang)。其中：數(shu)(shu)控(kong)常(chang)用加工機(ji)(ji)床(chuang)、數(shu)(shu)控(kong)車床(chuang)、數(shu)(shu)控(kong)鏜床(chuang)、數(shu)(shu)控(kong)龍門銑床(chuang)、數(shu)(shu)控(kong)成型折(zhe)彎機(ji)(ji)出(chu)口增(zeng)長均超(chao)過數(shu)(shu)控(kong)折(zhe)彎機(ji)(ji)整體(ti)增(zeng)速(su)。

在我們(men)(men)的(de)日(ri)常(chang)(chang)生活中(zhong)，我們(men)(men)經常(chang)(chang)可以接觸(chu)到(dao)管(guan)(guan)件(jian)(jian)的(de)使用范(fan)圍。我認為(wei)管(guan)(guan)件(jian)(jian)深加(jia)工(gong)生產(chan)的(de)所有產(chan)品都(dou)應該屬于(yu)(yu)管(guan)(guan)件(jian)(jian)的(de)范(fan)圍。我國管(guan)(guan)道(dao)加(jia)工(gong)機的(de)專業彎管(guan)(guan)機是將(jiang)管(guan)(guan)件(jian)(jian)彎曲(qu)成適合(he)客戶需求的(de)弧形彎頭(tou)管(guan)(guan)件(jian)(jian)。由(you)于(yu)(yu)管(guan)(guan)道(dao)是通過深加(jia)工(gong)成為(wei)商品的(de)原料，這(zhe)類產(chan)品具有管(guan)(guan)道(dao)和(he)機械零(ling)件(jian)(jian)的(de)雙重特點，是兩者(zhe)的(de)結合(he)。

管(guan)(guan)(guan)(guan)道是(shi)管(guan)(guan)(guan)(guan)件(jian)所必(bi)需的原料，但管(guan)(guan)(guan)(guan)件(jian)的加(jia)(jia)工(gong)方法很多(duo)，只要是(shi)機(ji)械(xie)加(jia)(jia)工(gong)，就可以應用。我(wo)認為管(guan)(guan)(guan)(guan)件(jian)在國外(wai)發(fa)展(zhan)如此之快有兩(liang)個突出的優點:*它可以替(ti)代(dai)一些機(ji)械(xie)加(jia)(jia)工(gong)商(shang)品，比機(ji)械(xie)加(jia)(jia)工(gong)零件(jian)、鑄件(jian)、零件(jian)輕，節省(sheng)材(cai)料；二是(shi)比機(ji)械(xie)加(jia)(jia)工(gong)商(shang)品節省(sheng)工(gong)藝、工(gong)作時間(jian)，降(jiang)低工(gong)件(jian)成本。管(guan)(guan)(guan)(guan)件(jian)種類繁(fan)多(duo)，可總結為以下(xia)主要類型(xing):變(bian)直徑管(guan)(guan)(guan)(guan)件(jian)，是(shi)指管(guan)(guan)(guan)(guan)端或管(guan)(guan)(guan)(guan)道某一部分(fen)直徑減小；變(bian)厚管(guan)(guan)(guan)(guan)件(jian)是(shi)指沿管(guan)(guan)(guan)(guan)道長度方向變(bian)厚。

根據(ju)需要，將圓(yuan)形段變為方(fang)(fang)形、橢(tuo)圓(yuan)形、多邊(bian)形等。；彎(wan)曲(qu)管(guan)件，我們(men)接觸更多，是將接管(guan)變成(cheng)不同曲(qu)率半徑的彎(wan)頭，如(ru)彎(wan)頭、彎(wan)頭等。；帶(dai)凸平臺和圓(yuan)邊(bian)緣的管(guan)件，前(qian)者是指(zhi)管(guan)頂(ding)向(xiang)(xiang)內或(huo)外凸起，后者是指(zhi)在管(guan)周方(fang)(fang)向(xiang)(xiang)產(chan)生(sheng)凸起或(huo)凹槽的管(guan)件；帶(dai)卷(juan)邊(bian)和封底的管(guan)件，增(zeng)加管(guan)端總強度，向(xiang)(xiang)管(guan)外或(huo)內側卷(juan)起或(huo)封閉管(guan)件頂(ding)部的管(guan)件；

擴徑管(guan)(guan)件(jian)，按規定(ding)擴大管(guan)(guan)件(jian)頂部或某個位置(zhi)，產(chan)生各種形(xing)(xing)狀的管(guan)(guan)件(jian)；管(guan)(guan)件(jian)的加(jia)(jia)工(gong)方法(fa)(fa)有很(hen)多(duo)種。很(hen)多(duo)也屬(shu)于機(ji)(ji)械加(jia)(jia)工(gong)范圍，采用沖壓(ya)法(fa)(fa)、鑄造(zao)法(fa)(fa)、滾(gun)輪(lun)加(jia)(jia)工(gong)法(fa)(fa)、滾(gun)壓(ya)法(fa)(fa)、膨脹(zhang)法(fa)(fa)、拉伸法(fa)(fa)、彎(wan)曲(qu)法(fa)(fa)和(he)組(zu)合加(jia)(jia)工(gong)法(fa)(fa)。管(guan)(guan)件(jian)加(jia)(jia)工(gong)是(shi)機(ji)(ji)加(jia)(jia)工(gong)與金屬(shu)壓(ya)力加(jia)(jia)工(gong)的有機(ji)(ji)結合。例如：液(ye)壓(ya)彎(wan)曲(qu)法(fa)(fa)：將液(ye)壓(ya)彎(wan)管(guan)(guan)機(ji)(ji)管(guan)(guan)道(dao)(dao)放(fang)入彎(wan)管(guan)(guan)機(ji)(ji)模(mo)具中，用液(ye)壓(ya)動(dong)力將管(guan)(guan)道(dao)(dao)彎(wan)曲(qu)成弧度(du)，加(jia)(jia)工(gong)外觀不變形(xing)(xing)。液(ye)壓(ya)彎(wan)曲(qu)法(fa)(fa):將管(guan)(guan)道(dao)(dao)準(zhun)確放(fang)入壓(ya)彎(wan)機(ji)(ji)上，也采用模(mo)具壓(ya)盤(pan)將管(guan)(guan)道(dao)(dao)彎(wan)曲(qu)效果好，加(jia)(jia)工(gong)管(guan)(guan)道(dao)(dao)面積(ji)廣。
