The opening width of the V-groove 8 is larger than the diameter of the rotating tube roller 7. This prevents the tube 15 from touching the V-groove 8 during rotation, thus avoiding uneven heating of the tube 15.
[0021] The support assembly includes a fixed plate 9 and a support side plate 10. The upper end of the fixed plate 9 is fixedly connected to the guide assembly, and the two sides of the fixed plate 9 are detachably fixed to the support side plate 10.

[0024] The working principle of the utility model is as follows:
[0025] The device is installed on the flaring machine, when the pipe 15 is heated, the pipe 15 is uniformly laid between the two rotating tube rollers 7 in the middle of the V-shaped groove 8, the pressing cylinder 1 drives the fixed plate 9, the pressing base 4 and the pressing soft plate 5 to descend, so that the pressing soft plate 5 and the pipe 15 are tightly attached, the rotating tube cylinder 2 starts to work, the rotating tube cylinder 2 extends and retracts to drive the base support plate 3 to move back and forth along the direction of the guide rail 16, so that the base support plate 3 drives the pressing base 4 and the pressing soft plate 5 to move back and forth, and the pipe 15 rotates between the pressing soft plate 5 and the rotating tube roller 7 under the action of friction, so that the uniform heating of the pipe 15 in the heating process is ensured.
