[0002] In construction, steel bars are a key building material. A large amount of steel bars are usually supplied in coils before use. These coiled steel bars have a certain degree of bending deformation due to the coiling process. Building structures have high requirements for the shape and dimensional accuracy of steel bars. In concrete structures, steel bars need to act as a skeleton to withstand various stresses such as tension and compression. If the steel bars are bent and not straight, it will not only affect the effective arrangement of the steel bars in the concrete, but may also lead to a decrease in the synergistic performance between the steel bars and the concrete. Steel bar straightening machines can quickly and accurately straighten steel bars through mechanical transmission, automatic control and other technical means.

[0003] In the existing technology, the straightening roller is fixed by multiple bolts. When disassembling the straightening roller, these bolts need to be loosened one by one, which is cumbersome and time-consuming. In particular, when the bolts are rusted or deformed due to long-term use, the disassembly difficulty will be further increased, which seriously affects the overall working efficiency of the rebar straightening machine.

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figure 1 - Figure 4This utility model provides an embodiment of a rebar straightening machine for construction, comprising a base plate 1, a fixed frame 2 fixedly connected to the upper surface of the base plate 1, a straightening cylinder 3 rotatably connected inside the fixed frame 2, a locking block 4 slidably connected to the inner wall of the straightening cylinder 3, a connecting cylinder 5 fixedly connected to the outer wall of the locking block 4, a fixed frame 8 fixedly connected to the outer wall of the connecting cylinder 5, a straightening roller 9 disposed inside the fixed frame 8, one end of a spring 6 fixedly connected to the inner wall of the fixed frame 2, and a ring 7 fixedly connected to the other end of the spring 6, the outer wall of the ring 7 slidably connected to the outer wall of the connecting cylinder 5, the outer wall of the ring 7 slidably connected to the outer wall of the straightening cylinder 3, and the inner wall of the fixed frame 2 fixedly connected to... A limiting post 10 is provided, with a limiting cap 11 fixedly connected to one end of the limiting post 10 away from the fixed frame 2. The inner side of the ring 7 is slidably connected to the outer wall of the limiting post 10, and the outer wall of the spring 6 is slidably connected to the outer wall of the limiting post 10. A straightening cylinder 16 is rotatably connected inside the fixed frame 2. A rotating assembly is provided on the upper surface of the fixed frame 2. The rotating assembly includes a motor 12, with the outer wall of the motor 12 fixedly connected to the upper surface of the fixed frame 2. A pulley 13 is fixedly connected to the output end of the motor 12. A belt 14 is provided on the outer wall of the pulley 13. A pulley 15 is provided on the inner wall of the belt 14. The inner wall of the pulley 15 is fixedly connected to the outer wall of the straightening cylinder 16.

[0027] Specifically, the base plate 1 can fix the fixed frame 2. The straightening cylinder 3, which is rotatably connected inside the fixed frame 2, is used for the insertion of the reinforcing bar. The locking block 4 can fix the connecting cylinder 5. The connecting cylinder 5 can fix the fixed frame 8. The fixed frame 8 can fix the straightening roller 9. The straightening roller 9 is used to straighten the reinforcing bar in the rotating state. The spring 6 can push and reset the ring 7. When the straightening roller 9 is not disassembled, the spring 6 pushes the ring 7 to fix the connection between the locking block 4 and the straightening cylinder 3, thereby ensuring the stability of the straightening roller 9 when rotating. The limiting post 10 can limit the ring 7 to prevent the ring 7 from rotating synchronously when the connecting cylinder 5 rotates. The fixed frame 2 can fix the motor 12 to ensure the smooth operation of the motor 12.

[0028] Reference Figure 1 and Figure 5 A rectangular frame 17 is fixedly connected to the upper surface of the base plate 1, and a rectangular groove 18 is provided on the upper surface of the rectangular frame 17.

[0029] Specifically, the base plate 1 can fix the rectangular frame 17.

[0030] Reference Figure 1 and Figure 5A rotating column 19 is rotatably connected inside the rectangular frame 17, and a disc 20 is fixedly connected to the outer wall of the rotating column 19. Sliding balls 22 are slidably connected to both ends of the disc 20, and a U-shaped seat 21 is fixedly connected to the outer wall of the sliding balls 22. The outer wall of the U-shaped seat 21 is slidably connected to the inner wall of the rectangular groove 18. A cylinder 23 is fixedly connected to the upper surface of the U-shaped seat 21, and a steel brush 24 is provided on the inner wall of the cylinder 23. A third pulley 25 is fixedly connected to the outer wall of the rotating column 19, and a second belt 26 is provided on the outer wall of the third pulley 25. A linkage pulley 27 is provided on the inner wall of the second belt 26, and the inner wall of the linkage pulley 27 is fixedly connected to the outer wall of the straightening cylinder 16.

[0031] Specifically, when the rotating column 19 rotates, it rotates inside the rectangular frame 17. The rectangular frame 17 supports the rotation of the rotating column 19. The rotating column 19 is fixedly connected to the disk 20, and the rotating column 19 can fix the disk 20. When the rotating column 19 rotates, it causes the disk 20 to rotate. When the disk 20 rotates, it causes the slider 22 to slide at both ends of the disk 20. Since the disk 20 is placed at an angle, the position of the slider 22 changes when the disk 20 rotates, causing the slider 22 to drive the U-shaped seat 21 to slide back and forth in the rectangular groove 1. The rectangular groove 18 on the inner wall of the 8 can limit the movement of the U-shaped seat 21 and also provide smooth movement of the U-shaped seat 21. The U-shaped seat 21 can fix the cylinder 23. The steel brush 24 set on the inner wall of the cylinder 23 can rub and remove rust from the straightened steel bar. When the straightening cylinder 26 rotates, it will drive the linkage pulley 27 to rotate, which in turn causes the belt 26 to drive the rotating column 19 to rotate inside the rectangular frame 17 through the pulley 3 25. The straightening and rust removal of the steel bar can be carried out in a coordinated manner without the need for intermediate transfer process, which improves the timeliness of rust removal and improves work efficiency.

[0032] Working principle: During use, the reinforcing bar is placed inside the straightening cylinder 3. After passing through the clamping block 4 and connecting cylinder 5, the reinforcing bar comes into contact with the inner wall of the straightening roller 9. The motor 12 is started, which causes the pulley 13 to rotate, which in turn causes the belt 14 to drive the straightening cylinder 16 to rotate via the pulley 15. The rotation of the straightening cylinder 16 drives the fixed frame 8 to rotate, which in turn causes the straightening roller 9 to rotate and straighten the reinforcing bar. During long-term use, the straightening roller 9 is prone to wear and requires maintenance. When the straightening roller 9 needs to be replaced, move the ring 7 outward to make it slide out of the outer wall of the connecting cylinder 5, and then slide on the outer wall of the straightening cylinder 3. During the movement of the ring 7, the limiting post 10 will be passively slid inside the ring 7, causing the spring 6 to contract under force. When the ring 7 slides past the connection between the locking block 4 and the straightening cylinder 3, the locking block 4 can be driven by the connecting cylinder 5 to slide out from the inner wall of the straightening cylinder 3, thereby completing the quick disassembly of the straightening roller 9. This achieves the effect of quick disassembly of the straightening roller 9, allowing maintenance personnel to easily and promptly remove and replace or repair the worn straightening roller 9, ensuring normal operation, reducing downtime, and improving work efficiency. After the straightening roller 9 straightens the steel bar, the straightened steel bar exits through the straightening cylinder 16 and enters the interior of the cylinder 23. During the rotation of the straightening cylinder 16, the straightening cylinder 16 drives the linkage pulley 27 to rotate. The rotation of the linkage pulley 27 drives the pulley 25 to rotate through the belt 26. The rotation of the pulley 25 drives the rotating column 19 to rotate inside the rectangular frame 17 and drives the disc 20 to rotate. When the disc 20 rotates, the sliding ball 22 is passively slid on the outer walls of both ends of the disc 20 and causes the U-shaped seat 21 to reciprocate and slide on the inner wall of the rectangular groove 18. This causes the cylinder 23 to drive the steel brush 24 to reciprocate and perform rust removal treatment on the straightened steel bar, thus ensuring that all parts of the steel bar surface are effectively rust-removed, resulting in a high-quality rust removal effect.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
