[0026] The following will be combined with specific embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0027] The following is combined with Figure 1 To the attached Figure 5 And specific embodiments discuss the present invention in detail.

[0028] like Figures 1 to 5 As shown, the utility model provides a torsion device for processing hot-rolled ribbed steel bars, including a base 1 and a fixed seat 2, a lifting assembly 3 is provided in the fixed seat 2, a torsion piece 4 is provided on the outside of the fixed seat 2, the torsion piece 4 is connected to the lifting assembly 3, the lifting assembly 3 is used to move the torsion piece 4 up and down, the lifting assembly 3 includes a rotating rod 5 and a driving member 6, the driving end of the driving member 6 is connected to the rotating rod 5, the torsion piece 4 is connected to the rotating rod 5, when the driving member 6 drives the rotating rod 5 to rotate, the torsion piece 4 is in an up and down moving state.

[0029] In this embodiment, the device consists of a stable base 1 and a fixed base 2 mounted thereon. The base 1 is responsible for supporting the entire device and ensuring that it remains stable during operation; the fixed base 2 carries key mechanical components and is the core part for realizing the steel bar torsion function. A lifting assembly 3 is integrated inside the fixed base 2, which mainly includes two parts: a rotating rod 5 and a driving member 6. The driving member 6 is connected to the rotating rod 5 through its driving end, and the rotating rod 5 is connected to the torsion member 4 located outside the fixed base 2. When the driving member 6 is started, it will drive the rotating rod 5 to rotate, thereby causing the torsion member 4 connected thereto to move up and down in the vertical direction. The design of the torsion member 4 is intended to achieve effective grasping and torsion of hot-rolled ribbed steel bars. As the driving member 6 runs, the rotation of the rotating rod 5 is converted into linear motion of the torsion member 4, so that it can be accurately adjusted to the required position, thereby completing the torsion operation of the steel bar.

[0030] In this embodiment, the driving member 6 is a hydraulic driving motor, and a driving end of the hydraulic driving motor is connected to one end of the rotary rod 5 .

[0031] Hydraulic drive motors can generate far greater torque than electric motors or other types of drives, which is crucial for twisting thick or hard hot-rolled ribbed steel bars, which require greater force. The working characteristics of the hydraulic system determine that it can provide very smooth power output during operation and maintain a stable speed even under large load changes, which is very important for ensuring processing quality and improving production efficiency.

[0032] In this embodiment, the torsion member 4 includes a connecting rod 7 and a torsion block 8 . One end of the connecting rod 7 is threadedly connected to the rotating rod 5 , and the other end is connected to the torsion block 8 .

[0033] In this embodiment, the protruding length of the connecting rod 7 can be adjusted according to actual processing requirements through a threaded connection, thereby changing the position of the torsion block 8 relative to the base 1, and realizing adaptive processing of ribbed steel bars of different lengths or sizes. The threaded connection makes the assembly and disassembly between the connecting rod 7 and the rotating rod 5 simple and quick, which is convenient for users to replace or repair parts when needed, reducing maintenance costs. The tight threaded fit between the connecting rod 7 and the rotating rod 5 can ensure that there is no relative sliding between the two during the torsion process, ensuring the accuracy and consistency of the torsion action and improving the processing accuracy. The torsion block 8 is directly connected to the connecting rod 7 to withstand the reaction force from the ribbed steel bars, while the connecting rod 7 is firmly fixed to the rotating rod 5 through threads, which can effectively disperse and transmit force, reduce the wear of individual components, and extend the service life.

[0034] In this embodiment, a slot for the ribbed steel bar to pass through is provided on the end surface of the torsion block 8, and a fixing block 9 is provided on the side wall of the slot.

[0035] In this embodiment, the design of the slot ensures that the ribbed steel bars can be accurately positioned in the torsion block 8, which helps to maintain the stable position of the steel bars during processing, avoids processing errors caused by position offset, and improves processing accuracy. The fixed block 9 on the side wall of the slot can tightly grasp the ribbed steel bars to prevent them from sliding or falling out during the torsion process, ensuring the safety and effectiveness of the torsion operation. By adjusting the position of the fixed block 9 or replacing torsion blocks 8 of different specifications, it can adapt to ribbed steel bars of different diameters and types, enhancing the versatility and flexibility of the equipment. The design of the fixed block 9 takes into account the protection of the surface of the ribbed steel bars, avoiding scratches or damage that may be caused by direct hard contact, and maintaining the surface quality of the steel bars. Since the fixed block 9 can quickly and firmly clamp the ribbed steel bars, a lot of time can be saved when loading and unloading the steel bars, thereby improving the overall processing efficiency. The fixed block 9 is easy to operate, and workers can easily put the ribbed steel bars into the slot and fix them, simplifying the operating process and reducing labor intensity.

[0036] In this embodiment, the torsion device further includes a fixing mechanism, which includes a fixed hydraulic jaw 10 and a jaw hydraulic cylinder 11 . The fixed hydraulic jaw 10 is arranged on the end surface of the base 1 , and the jaw hydraulic cylinder 11 is arranged inside the base 1 .

[0037] In this embodiment, the jaw hydraulic cylinder 11 can adjust the clamping force provided according to needs, which not only ensures the effective fixation of the ribbed steel bars, but also avoids the problem of deformation or damage of the steel bars due to excessive clamping force. The fixed hydraulic jaws 10 move quickly and can complete the clamping of the ribbed steel bars in a short time, greatly shortening the preparation time and production cycle. The automated fixing mechanism reduces the chance of direct contact between the operator and the equipment, reducing the risk of work-related accidents. At the same time, the overload protection function of the hydraulic system further ensures the safe operation of the equipment. The fixed hydraulic jaws 10 can be adjusted according to ribbed steel bars of different diameters and shapes. By replacing different jaws or adjusting the pressure of the hydraulic cylinder, it can be suitable for processing steel bars of various specifications. Integrating the jaw hydraulic cylinder 11 inside the base 1 not only saves space, but also makes the appearance of the entire device more tidy, which is conducive to optimizing the workshop layout.

[0038] In this embodiment, a circular groove for the ribbed steel bar to extend into is formed on the end surface of the fixed hydraulic jaw 10, and a fixing ring 12 for fixing the ribbed steel bar is provided on the side wall of the circular groove.

[0039] In this embodiment, the design of the circular groove allows the ribbed steel bars to be accurately placed in the predetermined position, ensuring the alignment accuracy during the processing process and helping to improve the quality of the final product. The fixed ring 12 fits tightly against the side wall of the circular groove and can effectively clamp the ribbed steel bars to prevent them from displacement or vibration during processing, thereby ensuring the stability of processing. The contact surface between the fixed ring 12 and the ribbed steel bars is relatively soft, which can reduce scratches or damage to the surface of the steel bars and maintain the original state of the steel bars. By adjusting the size of the fixed ring 12 or using fixed rings 12 of different specifications, ribbed steel bars of different diameters can be adapted, increasing the scope of application of the equipment. The design of the fixed ring 12 facilitates the rapid loading and unloading of ribbed steel bars, reduces the time required for each steel bar replacement, and improves processing efficiency. The operator only needs to insert the ribbed steel bars into the circular groove and then activate the fixed ring 12 through the hydraulic system to achieve rapid fixation, simplifying the operating steps.

[0040] In this embodiment, one end surface of the fixing ring 12 is used to fix the end of the ribbed steel bar, and the other end of the fixing ring 12 is connected to the driving end of the jaw hydraulic cylinder 11.

[0041] In this embodiment, the fixed ring 12 can apply pressure quickly and evenly through the drive of the jaw hydraulic cylinder 11, ensuring the stable fixation of the ribbed steel bars during the processing, thereby improving the processing efficiency. The driving end of the hydraulic cylinder can accurately adjust the pressure applied to the fixed ring 12 through the control system, thereby adapting to ribbed steel bars of different diameters and hardnesses, and avoiding damage caused by improper clamping force. The linkage design of the fixed ring 12 and the hydraulic cylinder realizes automated operation, reduces manual intervention, reduces labor intensity, and also reduces the possibility of human error. The end face of the fixed ring 12 that contacts the ribbed steel bar is specially treated to reduce scratches or damage to the surface of the steel bar and maintain the surface quality of the steel bar. By replacing fixed rings 12 of different specifications or adjusting the pressure of the hydraulic cylinder, the device can adapt to ribbed steel bars of various specifications, thereby enhancing the versatility and flexibility of the equipment.

[0042] The staff has further described the present invention with the help of specific embodiments above, but it should be understood that the specific description here should not be understood as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
