This telescopic component is a first telescopic component 61. The direction of arrow F in the figure is the direction of expansion of the first telescopic component.
[0020] The expanded diameter end rotates driven by the first motor, and the direction of the arrow J in the figure is the direction of rotation of the expanded diameter end, and under the action of the first telescopic component, it is screwed into the end of the steel pipe, so as to achieve the expansion of the end of the steel pipe; its characteristic is that: a rolling roller 7 is also installed on the expanded diameter end, and the rolling roller has a central axis, and the central axis is arranged parallel to the length direction of the steel pipe, and the rolling roller is installed on the device body through the telescopic component, and this telescopic component is the second telescopic component 62, and the direction of the arrow D in the figure is the direction of telescopic extension of the second telescopic component, and the extension direction of the second telescopic component is toward the end of the steel pipe.
[0021] The utility model is arranged in this way, so that in the process of expanding the diameter of the steel pipe, the rolling roller can be used to roll the outer side of the expanded diameter portion of the steel pipe, thereby reducing the generation of cracks and achieving the purpose of the utility model.
[0022] Furthermore, the rolling roller is also connected to a motor, which is a second motor 52. The second motor rotates to drive the rolling roller to roll the outside of the processed steel pipe end. The direction of the arrow H in the figure is the direction of rotation of the rolling roller.
[0023] The utility model is arranged in this way, so that the rolling roller can actively rotate during the rolling process, and the generation of cracks can be further reduced.
[0024] Furthermore, the second telescopic component is also installed on the device body through a telescopic component, which is the third telescopic component 63.
