螺旋風管加工的方法

  • 點擊數:397

1、鑄造方法:用型鍛機沖壓管道頂部或部分,降低外徑。常見的型鍛機有旋轉式、連桿式和滾軸式。

2、滾輪法:將芯子放入不銹鋼管中,外界用滾軸推壓,進行圓緣加工。

3、沖壓方法:用帶錐度的芯子將管端擴展到所需的尺寸形狀。

4、彎曲成型法:常見的方法有三種,一種叫伸展法,另一種叫沖壓法,第三種有3-4個輥、兩個固定輥、一個調節輥、調節固定輥距,成品管件彎曲。

5、軋制方法:一般不使用芯棒,適用于厚壁管內側圓緣。

6、膨脹方法:在螺旋風管中放置橡膠,用沖子壓縮,使管道突出成型;另一種方法是液壓膨脹,在管道中間填充液體,液壓將管道膨脹成所需的形狀,波紋管的生產主要采用這種方法。
