[0037] The working principle of this utility model is as follows: When in use, the metal pipe to be bent is inserted between the fully grooved bending disc 7 and the semi-groove bending disc 8. At this time, the bending drive motor 12 drives the bending rotating frame 2 to rotate around the axis of the semi-groove bending disc 8 through the rotating shaft. The metal pipe can be bent by rotating the limiting block 6 and the fully grooved bending disc 7. After bending, the hydraulic drive cylinder 50 in the hydraulic drive rack 5 drives the hydraulic telescopic rod 51 to push forward. This drives the semi-groove bending disc 8 to rotate through the adjusting ring tooth 82 meshing with the drive rack 52, so that the semi-groove bending seat 81 rotates to the other side away from the fully grooved bending disc 7. In this way, the bent metal pipe can be easily removed. By rotating the adjusting screw 26, the position of the rotating limiting block 6 in the limiting groove 25 can be adjusted through the adjusting screw hole 64 connected to it. This allows for quick adjustment of the distance between the rotating limiting block 6 and the fully grooved bending disc 7, which can be conveniently adjusted and adapted to different bending requirements.
