    • An apparatus for working a surface of a metal pipe is provided. The apparatus comprises a drawing unit for drawing a metal pipe to reduce a diameter thereof, and a working assembly for working the diameter-reduced metal pipe to form an inner surface and/or an outer surface thereof into a predetermined configuration. The working assembly includes a rolling unit and a driving mechanism therefor. The rolling unit includes a housing, a plurality of rolling rolls rotatably disposed within the housing and outside the metal pipe so that the rolling rolls have their respective axes extending at an inclination angle with respect to an axis of the metal pipe. The rolling rolls are respectively mounted on support shafts rotatably supported in the housing through thrust bearings. The driving mechanism drivingly rotates the rolling unit to revolve the rolling rolls around the metal pipe. The rolling unit is removably mounted on the driving mechanism.
    • 提供了一种用于加工金属管表面的设备。 该装置包括用于拉伸金属管以减小其直径的拉伸单元,以及用于对直径减小的金属管进行加工以形成预定结构的内表面和/或外表面的工作组件。 工作组件包括滚动单元及其驱动机构。 滚动单元包括壳体,多个滚动辊,其可旋转地设置在壳体内并且在金属管外部,使得滚动辊具有相对于金属管的轴线倾斜倾斜的角度。 轧辊分别安装在通过推力轴承可旋转地支撑在壳体中的支撑轴上。 驱动机构使轧制单元驱动旋转,使轧制辊围绕金属管旋转。 滚动单元可拆卸地安装在驱动机构上。
