[0024] Furthermore, a pair of fixed blocks 9 are fixed at the bottom of the mounting frame 3, and a connecting shaft 10 is connected between the two fixed blocks 9 for common rotation. Both ends of the connecting shaft 10 are fixedly sleeved with rollers 11 that form rolling contact with the base plate 1. When the mounting frame 3 moves, it can be rolled and supported on the base plate 1 by the rollers 11, thereby stabilizing its movement process and reducing movement resistance.
[0025] Furthermore, a guide rod 14 is fixed on the rack 2, and a guide plate 12 is fixed on the side of the mounting frame 3. The guide rod 14 passes through the guide hole 13 on the guide plate 12. Through the sliding cooperation between the guide plate 12 and the guide rod 14, the mounting frame 3 can be limited and stabilized.
[0026] Furthermore, a first support plate 15 is fixed on the top of the bottom plate 1, and a cooler 16 is fixed on the top of the first support plate 15. The rolled portion of the steel pipe enters the cooler 16, and the cooler 16 cools the portion of the steel pipe to shape it.
[0027] Furthermore, a second support plate 17 is fixed on the top of the bottom plate 1, and a support plate 18 for supporting the steel pipe is fixed on the top of the second support plate 17. The steel pipe can be supported by the support plate 18, so that the steel pipe can be smoothly pushed forward.
[0028] Furthermore, a U-shaped support frame 19 is fixed on the top of the base plate 1, and a pair of propulsion rollers 20 are rotatably connected to the support frame 19. A second motor 22 is fixed on the support frame 19, and the output shaft of the second motor 22 is connected to a main gear 23. An end fixed sleeve of one of the propulsion rollers 20 is provided with a sub-gear 24 meshing with the main gear 23. When the second motor 22 is started, the output shaft of the second motor 22 drives the main gear 23 to rotate, and the main gear 23 meshes to drive the sub-gear 24 to rotate. The sub-gear 24 synchronously drives the propulsion roller 20 to rotate, and the propulsion roller 20 can propel the steel pipe.
[0029] Furthermore, a rubber sleeve 21 is provided on the pushing roller 20. By providing the rubber sleeve 21, wear between the pushing roller 20 and the steel pipe can be avoided.
[0030] Working principle: The heated steel pipe is put on the rod core 8, and the output shafts of the two first motors 6 are periodically reversed at the same time. The output shaft of the first motor 6 drives the first gear 7 to rotate, and the first gear 7 engages with the rack 2, so that the mounting frame 3 moves back and forth along the length direction of the rack 2, and the pressure roller 5 will repeatedly roll this section of the steel pipe to ensure the rolling accuracy. Then the steel pipe is pushed forward, and the pressure roller 5 will roll the next section of the steel pipe. The rolled part of the steel pipe enters the cooler 16, and the cooler 16 will cool this part of the steel pipe to make it shape. When pushing the steel pipe, the output shaft of the second motor 22 drives the main gear 23 to rotate, and the main gear 23 engages to drive the sub-gear 24 to rotate, and the sub-gear 24 synchronously drives the propulsion roller 20 to rotate, and the propulsion roller 20 pushes the steel pipe.
