The threaded block 270 then moves the slider 260 along the guide rail 250, and the slider 260 moves the entire up-down adjustment assembly 170. Thus, the longitudinal position of the mold 180 can be adjusted. The structure is simple and the adjustment is precise.

The rotating disk 300 can drive the entire up-down adjustment assembly 170 to rotate by a certain angle. Then, the bolt 320 is tightened to fix the rotating disk 300 on the slider 260, thereby enabling the adjustment of the horizontal angle of the grinding tool 180 and improving the flexibility of the entire device.
[0053] In some preferred embodiments, the motor 190 and the mold 180 are driven by a belt 330, with the mold 180 located on one side of the support 210 and the motor 190 located on the other side of the support 210.
[0054] Understandably, by setting up belt 330, motor 190 drives mold 180 to rotate via belt 330, thereby allowing for flexible arrangement of motor 190 and making the overall equipment compact.

The flap wheel 350 can continuously grind the weld seam of the welded pipe, resulting in high work efficiency. At the same time, the flap wheel 350 also has a certain degree of elasticity, which can prevent the welded pipe from being worn through.
[0057] Reference Figure 2 In some preferred embodiments, the support base 130 is provided with a groove 360, the cross section of the groove 360 is arc-shaped, and the groove 360 fits with the bottom of the welded pipe.
[0058] It is understandable that by setting the groove 360, the bottom of the welded pipe fits into the groove 360, and the force between the welded pipe and the groove 360 is uniform. When grinding the welded pipe, it can prevent the welded pipe from deforming under stress.
[0059] Reference Figure 1 and Figure 3 In some preferred embodiments, the feed roller assembly 120 includes a base 370 and two first rollers 380 rotatably connected to the base 370. The two first rollers 380 are vertically arranged, and the circumferential surfaces of the two first rollers 380 abut against the two sides of the welded pipe respectively.
