[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0022] Reference Figures 1-3 A concrete utility pole rebar straightening machine includes a base plate 7. A heating assembly is provided on the upper surface of the base plate 7. A support frame 8 is bolted to the upper surface of the base plate 7. Multiple grooves 9 are formed on the top of the support frame 8. A rotating ring 1 is rotatably connected within each groove 9, and the grooves 9 restrict the position of the rotating ring 1. Multiple straightening tubes 2 of different diameters are inserted and fixed inside the rotating ring 1. One end of each straightening tube 2 is connected to a conical block 3. A slot 11 is formed on one side of the rotating ring 1, and a clamping bracket 10 is clamped within the slot 11. A connecting frame 13 is bolted to one side of the clamping bracket 10. A magnetic block 14 is bolted to the outer wall of one side of the support frame 8, and the connecting frame 13 contacts the magnetic block 14. The contact surface of 4 is made of iron. Pull the connecting frame 13 outward to move the card holder 10 out of the card slot 11. At the same time, the connecting frame 13 separates from the magnetic block 14. Then rotate the rotating ring 1 to move the diameter of the reinforcing bar of the utility pole that needs to be straightened, so that the straightening tube 2 of the appropriate size moves until it corresponds to the position of the heating tube 4. Then reset the connecting frame 13 and the card holder 10. The upper surface of the base plate 7 is fixed with a fixing frame 19 by bolts. The upper surface of the fixing frame 19 is provided with a conveying component. Then pass the reinforcing bar of the utility pole that needs to be straightened through the heating component to heat the reinforcing bar. Then the reinforcing bar of the utility pole continues to move into the straightening tube 2 at the corresponding position for straightening. The conveying component drives the straightened reinforcing bar of the utility pole to move.

[0023] In this invention, it should be noted that the conveying assembly includes a bidirectional threaded rod 18, which is rotatably connected to the top of the fixed frame 19. Two slides 17 are threadedly connected to the outer side of the bidirectional threaded rod 18, and rotating rollers 16 are rotatably connected to the outer side of each slide 17. A motor is bolted to one side of one of the slides 17, and one end of the motor's output shaft is fixed to the adjacent rotating roller 16. The reinforcing bar of the utility pole continues to move into the corresponding straightening tube 2 for straightening, then passes between the two rotating rollers 16. Rotating the bidirectional threaded rod 18 causes the slides 17 to move inwards and contact the reinforcing bar. The motor is started, causing the corresponding rotating roller 16 to rotate, thereby moving the straightened reinforcing bar. The top of the fixed frame 19 is bolted... A positioning post 15 is fixed, and the slide 17 is slidably connected to the positioning post 15. The positioning post 15 can guide the slide 17 to move stably and prevent the slide 17 from tilting. The heating component includes two support blocks 6, which are fixed to the upper surface of the base plate 7 by bolts. A heating tube 4 is fixed between the two support blocks 6 by bolts, and the heating tube 4 corresponds to the position of one of the straightening tubes 2. Multiple heating wires 5 are installed inside the heating tube 4. The heating wires 5 soften the steel bar of the pole and remove rust at the same time. Two guide rods 12 are fixed to the bottom of the connecting frame 13 by bolts, and the support frame 8 is slidably connected to the guide rods 12. The guide rods 12 can guide the connecting frame 13 to move stably. A knob is welded to the top of the bidirectional threaded rod 18.

[0024] Working principle: When straightening the reinforcing bars, first pull the connecting frame 13 outward, causing it to move the clamp 10 out of the clamp slot 11. At the same time, the connecting frame 13 separates from the magnetic block 14. Then, rotate the rotating ring 1 to move the diameter of the reinforcing bar to be straightened, so that the appropriate size straightening tube 2 moves until it corresponds to the position of the heating tube 4. Then, reset the connecting frame 13 and the clamp 10. Then, the worker passes the reinforcing bar to be straightened through the heating tube 4, so that the heating wire 5 heats and softens it. Then, the reinforcing bar continues to move into the straightening tube 2 at the corresponding position for straightening, and then passes between the two rotating rollers 16. Rotate the bidirectional threaded rod 18 to drive the slide 17 to move inward and contact the reinforcing bar. Start the motor, and the motor rotates to make the corresponding rotating roller 16 rotate, thereby moving the straightened reinforcing bar.
