[0002] A rebar bending machine for cast-in-place piles is a mechanical device specifically designed for bending rebars during the construction of cast-in-place piles. It helps construction workers to complete the rebar bending work efficiently and accurately, thereby ensuring the quality and stability of the entire pile foundation structure.

[0003] First, if the device does not have the function of controlling the bending length of the reinforcing bars, it will be unable to accurately control the bending length of the reinforcing bars, which may lead to the reinforcing bars not meeting the design requirements, increasing the risk of rework and material waste, and reducing the construction quality.

[0004] Secondly, if the device does not have the function of clamping different types and shapes of steel bars, it limits the scope of application of the device. It may be necessary to equip different clamps for different types and shapes of steel bars, which increases the cost and construction complexity.

[0005] Finally, if the device does not have the function of changing the bending direction of the reinforcing bars, it will limit the bending angle and direction of the reinforcing bars, which may not meet the design requirements of complex structures and affect the integrity and safety of the structure.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figures 1-5A rebar bending machine for cast-in-place piles includes a support 1, a moving mechanism, a clamping mechanism, and a running mechanism. The moving mechanism includes a motor 2 and a lead screw 3. The motor 2 is fixedly mounted on the support 1, and the lead screw 3 is fixedly mounted on the motor 2 and rotatably connected to the support 1. A sliding frame 4 is mounted on the support 1, and the sliding frame 4 is slidably connected to the support 1 and cooperates with the lead screw 3. Rollers 5 are mounted at the bottom of the sliding frame 4, and the rollers 5 are rotatably connected to the sliding frame 4 and slidably connected to the support 1. The clamping mechanism includes a first hydraulic cylinder 6 and a cooperating component 7. The first hydraulic cylinder 6 is fixedly mounted in the sliding frame 4, and the cooperating component 7 is mounted on the first hydraulic cylinder 6 and cooperates with the first hydraulic cylinder 6. An adjusting component 8 and a fixing component 9 are mounted on the first hydraulic cylinder 6, and the adjusting component 8 is rotatably connected to the first hydraulic cylinder 6. The fixing component 9 is mounted on the first hydraulic cylinder 6 and is slidably connected to the first hydraulic cylinder 6 and cooperates with the fixing component 9.

[0031] In this embodiment, the moving mechanism includes a motor 2 and a lead screw 3. In use, after clamping the reinforcing bar, the position of the reinforcing bar can be adjusted. The motor 2 drives the lead screw 3 so that the lead screw 3 engages with the first threaded hole 14 inside the sliding frame 4, thereby allowing the sliding frame 4 to slide inside the support 1. The roller 5 located at the bottom of the sliding frame 4 slides in the sliding groove 13 inside the support 1, completing the movement of the sliding frame 4 on the support 1. After one end of the reinforcing bar is bent, it may be necessary to bend the reinforcing bar again. At this time, the bending length can be controlled by the precise sliding of the lead screw 3 as described above, thus completing the processing of the workpiece.

[0032] In this embodiment, the clamping mechanism includes a first hydraulic cylinder 6 and a mating component 7. In use, the mating component 7 can be installed on the first hydraulic cylinder 6 first. When installing the mating component 7, the limiting block 20 on the mating component 7 can be placed into the limiting groove 22 of the connecting block 16. During installation, the adjusting component 8, which is rotatably connected by the connecting rod 17 and the connecting groove 18, is rotated in advance, so that the second threaded hole 15 in the adjusting component 8 and the screw 19 on the fixing component 9 are engaged and connected. The fixing component 9 slides in the connecting component. After the position of the mating component 7 is fixed, the fixing component 9 can be engaged and connected by the locking hole 21 according to the above operation, so that the position of the mating component 7 on the connecting block 16 is fixed. Then, the first hydraulic cylinder 6 drives the mating component 7 to clamp the steel bar, thus completing the fixation of the position of the steel bar.

[0033] In this embodiment, the operating mechanism includes a second hydraulic cylinder 10 and a force-receiving component 11. During use, one end of the reinforcing bar has exceeded the position of the fixed rod 12. At this time, the second hydraulic cylinder 10 can be directly driven, so that the force-receiving component 11 driven by the second hydraulic cylinder 10 can slide on the main body, and the pressing block 23 on the force-receiving component 11 directly contacts the reinforcing bar. Under the action of the fixed rod 12, the reinforcing bar is bent. At the same time, if the reinforcing bar needs to be bent continuously at different angles, it can be processed by a moving mechanism and a clamping mechanism.

[0034] Example 2:

[0035] In summary, during use, the mating part 7 can be installed on the first hydraulic cylinder 6 first. When installing the mating part 7, the limiting block 20 on the mating part 7 can be placed into the limiting groove 22 of the connecting block 16. During installation, the adjusting part 8, which is rotatably connected by the connecting rod 17 and the connecting groove 18, should be rotated in advance so that the second threaded hole 15 in the adjusting part 8 and the screw 19 on the fixing part 9 are engaged. The fixing part 9 slides in the connecting part. After the position of the mating part 7 is fixed, the fixing part 9 can be engaged with the locking hole 21 according to the above operation, so that the position of the mating part 7 on the connecting block 16 is fixed. Then, the first hydraulic cylinder 6 drives the mating part 7 to clamp the steel bar, thus fixing the position of the steel bar. After clamping the steel bar, the position of the steel bar can be adjusted. The motor 2 drives the lead screw 3 so that the lead screw 3 engages with the first threaded hole inside the sliding frame 4. 14. The threaded engagement allows the sliding frame 4 to slide inside the support 1. The roller 5 located at the bottom of the sliding frame 4 slides in the sliding groove 13 inside the support 1, completing the movement of the sliding frame 4 on the support 1. After one end of the steel bar is bent, it may be necessary to bend the steel bar again. At this time, the bending length can be controlled by the precise sliding of the lead screw 3 as described above, and the workpiece processing is completed. Specifically, during processing, one end of the steel bar has exceeded the position of the fixed rod 12. At this time, the second hydraulic cylinder 10 can be directly driven, so that the force-bearing component 11 driven by the second hydraulic cylinder 10 can slide on the main body, and the pressing block 23 on the force-bearing component 11 directly contacts the steel bar. Under the action of the fixed rod 12, the steel bar is bent. At the same time, if the steel bar needs to be bent continuously at different angles, the moving mechanism and the clamping mechanism can be used to complete the processing of the steel bar.

[0036] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
