[0027] By providing a detachable straightening upper mold 8 and a straightening lower mold 3, the straightening device can be adapted to metal pull ring rods of different sizes for straightening operations, and the metal pull ring rod is heated by the electric heating wire 4 before straightening, thereby improving the toughness of the metal pull ring rod, destroying the original stress distribution, and improving the straightening effect.

[0028] The bottom outer wall of the fixed top plate 6 is fixed with a hydraulic telescopic rod 7 by bolts, and the bottom of the hydraulic telescopic rod 7 is connected with a straightening upper mold 8, and the straightening upper mold 8 is adapted to the straightening lower mold 3. The outer wall of the arc-shaped mounting plate 14 is welded with an arc-shaped outer gear ring 15, and the bottom outer wall of the arc-shaped outer gear ring 15 is meshed with a first gear 16, and the axis of the first gear 16 is connected with a first servo motor 17;

[0029] The bottom outer wall of the driving rack 18 is meshed with a second gear 19 , and a rotating shaft 20 is welded at the axis of the second gear 19 . Both ends of the rotating shaft 20 are rotatably mounted on the fixed housing 9 .

[0030] A worm wheel 21 is welded to the outer wall of one side of the rotating shaft 20, and a worm 22 is meshed on the top of the worm wheel 21, and a second servo motor 23 is connected to the axis of the worm 22. Electric telescopic rods 24 are fixed to both ends of the outer wall of one side of the arc-shaped mounting plate 14 by bolts, and an arc-shaped clamping plate 25 is fixed to the piston rod of the electric telescopic rod 24;

[0031] When the metal pull ring rod is straightened, the meshing drive of the arc-shaped outer tooth ring 15 and the first gear 16 can drive the metal pull ring rod to rotate and adjust its position, thereby reducing the time consumed by manual rotation and further improving the processing effect of the bent metal pull ring rod.
