Description

Technical Field

[0001] The utility model relates to the technical field of steel bar bending, and particularly relates to a novel steel bar bender. Background Art

[0002] Steel bar benders play a crucial role in the construction and engineering fields. They are specifically responsible for precisely bending metal materials such as steel bars to specific angles and shapes. With efficient mechanical control and power drive, this equipment can accurately complete the bending tasks and adapt to steel bars of various specifications and materials.

[0003] In practical applications, especially when bending the middle part of the steel bar while the two ends are not restricted by clamping, the steel bar bender faces the challenge of bending deformation. Traditional benders mainly rely on the rotation of the working disk, combined with the movement of the central axis and the forming axis to achieve the bending of the steel bar. However, if the two ends of the steel bar are not effectively clamped, slippage may occur during the bending process, resulting in inaccurate shapes or deformations.

[0004] In terms of structural design, if the fixture of the steel bar bender is poorly designed or the clamping force is insufficient, it will further exacerbate the deformation during the bending process. In addition, the material properties of the steel bar, such as hardness, elastic modulus, etc., will also affect the degree of deformation during the bending process. Therefore, for steel bars of different materials, it may be necessary to adjust the parameter settings of the bender or adopt specific bending processes.

[0005] The skills and experience of the operator are equally crucial. Improper operations, such as too fast bending speed or too large bending angle, may cause the steel bar to deform. To ensure the bending quality, the operator needs to receive professional training and have sufficient experience.

[0006] In addition, after long-term use of the equipment, the wear and aging of each component may affect its working performance. Therefore, regular maintenance and servicing are the key to ensuring the continuous and stable operation of the steel bar bender. If the equipment fails to be maintained and serviced in a timely manner, it may exacerbate the deformation of the steel bar during the bending process. Content of the Utility Model

[0007] The main purpose of the utility model is to provide a novel steel bar bender, which can effectively solve the problems raised in the background art.

[0008] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0009] A new type of steel bar bender, comprising a base, side frames, a top frame, a linear motion actuator, a connecting seat, and a first steel bar limiting and bending roller. The two side frames are installed in parallel on the base, and the top frame is fixed on the two side frames. The linear motion actuator is fixed on the top frame by bolts, and a connecting seat is provided on the telescopic head of the linear motion actuator. The first steel bar limiting and bending roller is installed on the connecting seat;

[0010] A support shaft is inserted into the opening of each side frame, and a second steel bar limiting and bending roller adapted to the first steel bar limiting and bending roller is provided at the outer end of the support shaft. An adjusting screw is provided at the other end of the support shaft, and a fixing frame is installed at the rear end of each side frame, and the adjusting screw passes through the fixing frame;

[0011] The first steel bar limiting and bending roller and the second steel bar limiting and bending roller insert the steel bar and change the first steel bar limiting and bending roller to adjust the curvature of the steel bar. By rotating the adjusting screw, the protruding distance of the second steel bar limiting and bending roller is changed, and the curvature of both ends of the steel bar is adjusted by the protrusion of the second steel bar limiting and bending roller.

[0012] In a further preferred solution, a screw tube adapted to the adjusting screw is provided inside the fixing frame, and the stable adjustment of the adjusting screw is realized through the screw tube;

[0013] In a further preferred solution, a turning handle is provided at the tail end of the adjusting screw, and an anti-slip sleeve is provided on the surface of the turning handle. The connection between the turning handle and the adjusting screw is limited and fixed by a hexagonal nut;

[0014] In a further preferred solution, the second steel bar limiting and bending roller is installed on the support shaft through a limiting ring. A protruding ring is provided on the shaft of the support shaft. The movement of the support shaft towards the fixing frame is restricted by the protruding ring. The protruding ring contacts the side frame to make the second steel bar limiting and bending roller face the first steel bar limiting and bending roller. A ball is provided at the connection between the protruding ring and the side frame;

[0015] In a further preferred solution, the cross-section of the fixing frame is designed in an "Ω" shape. The fixing frame is fixed on the side frame by bolts, and the fixing frame is threadedly connected with the adjusting screw;

[0016] In a further preferred solution, annular grooves are provided on the side walls of the first steel bar limiting and bending roller and the second steel bar limiting and bending roller. The steel bar is embedded in the annular grooves, and the groove walls of the annular grooves are designed in an arc shape.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] In this utility model, by finely adjusting the protruding distance of the second steel bar limiting and bending roller, users can precisely control the bending curvature at both ends of the steel bar according to the specific engineering requirements. This high degree of adjustability not only meets the strict requirements of different projects for the bending accuracy of steel bars, but also greatly improves the flexibility and usage efficiency of the equipment. In practical applications, due to different engineering requirements, the bending requirements of steel bars also vary. At this time, the design advantages of the second steel bar limiting and bending roller are highlighted, and it can quickly and conveniently respond to these changes, thus ensuring that the bending of steel bars meets the requirements of various complex scenarios.

[0019] Precise bending control is crucial for reducing material waste. With the improvement of bending accuracy, we can effectively avoid material loss caused by insufficient or excessive bending, thereby reducing production costs. In addition, high-quality steel bar bending is the cornerstone for ensuring the overall project quality. By adjusting the second steel bar limiting and bending roller, we ensure the bending accuracy of the steel bar, thereby improving the overall quality of the project and the reliability of the product.

[0020] Steel bars with different diameters and materials have different requirements for the bending machine. However, with the flexible adjustment of the second steel bar limiting and bending roller, our steel bar bending machine can easily adapt to steel bars of various specifications and materials, demonstrating excellent adaptability and versatility. Users can easily adjust the position of the second steel bar limiting and bending roller through simple screw adjustment operations, making the operation process more convenient, intuitive, reducing the operation difficulty, and improving the work efficiency.

[0026] In order to make the technical means, creative features, achieved purposes, and functions of this utility model easy to understand, the following further elaborates this utility model in conjunction with specific embodiments. Embodiment

[0027] The new type of steel bar bender involved in this embodiment is as follows Figures 1 to 4 shown. Its main components include a base 1, side frames 2, a top frame 3, a linear motion actuator 4, a connecting seat 5, and a first steel bar limiting and bending roller 6. Two side frames 2 are installed parallel to each other on the base 1 to ensure the stability of the structure. The top frame 3 is firmly fixed on the tops of the two side frames 2 to provide support for the entire device. The linear motion actuator 4 is tightly fixed on the top frame 3 by bolts, and a connecting seat 5 is installed on its telescopic head for connecting and driving the first steel bar limiting and bending roller 6.

[0028] The design of the side frame 2 is quite distinctive. Each side frame 2 is provided with an opening, and a support shaft 8 is inserted into the opening. A second steel bar limiting and bending roller 7 adapted to the first steel bar limiting and bending roller 6 is installed at the outer end of the support shaft 8 to ensure that the two can work together. An adjusting screw 11 is provided at the other end of the support shaft 8 for adjusting the position of the second steel bar limiting and bending roller 7. A fixing frame 9 is installed at the rear end of each side frame 2, and the adjusting screw 11 passes through the fixing frame 9, thereby achieving stable adjustment.

[0029] During use, the user only needs to insert the steel bar between the first steel bar limiting and bending roller 6 and the second steel bar limiting and bending roller 7. By the telescoping of the linear motion actuator 4, the position of the first steel bar limiting and bending roller 6 is changed, thereby realizing the adjustment of the curvature of the steel bar. At the same time, the user can also change the protruding distance of the second steel bar limiting and bending roller 7 by rotating the adjusting screw 11. With this design, the user can more flexibly adjust the curvature at both ends of the steel bar.

[0030] The installation method of the second steel bar limiting and bending roller 7 is also worth mentioning. It is installed on the support shaft 8 through a limiting ring to ensure that it will not move randomly during work. A protruding ring is provided on the shaft of the support shaft 8. This design can limit the movement of the support shaft 8 in the direction of the fixing frame 9 to ensure that the second steel bar limiting and bending roller 7 is always facing the first steel bar limiting and bending roller 6. Ball bearings are also provided at the connection between the protruding ring and the side frame 2 to reduce friction and improve the service life of the device.

[0031] The design of the fixing frame 9 is also delicate. Its cross-section is in the shape of "Ω", which is not only beautiful but also can provide better support effect. The fixing frame 9 is fixed on the side frame 2 by bolts to ensure the stability of the structure. At the same time, the fixing frame 9 is threadedly connected with the adjusting screw 11, making the adjustment more stable and reliable.

[0032] Circular grooves are provided on the side walls of both the first steel bar limiting and bending roller 6 and the second steel bar limiting and bending roller 7. When the steel bar is embedded in the circular groove, it can effectively prevent the steel bar from sliding or misaligning during the bending process. The groove wall of the circular groove is in an arc shape, which matches the shape of the steel bar, further improving the practicality of the device. Embodiment

[0033] Based on Embodiment 1, this embodiment improves the adjusting screw 11. Specifically, a screw tube 10 adapted to the adjusting screw 11 is added inside the fixed frame 9. This design makes the adjusting screw 11 more stable during adjustment, reducing errors caused by shaking.

[0034] In addition, a turning handle 12 is provided at the tail end of the adjusting screw 11 for the convenience of users to operate. An anti-slip sleeve is provided on the surface of the turning handle 12, improving the stability of holding. The connection between the turning handle 12 and the adjusting screw 11 is limited and fixed by a hexagon nut to ensure a firm structure and prevent loosening due to external forces.

[0035] Usage process: Ensure that the steel bar bender is placed on a stable workbench and check whether all components are in good condition, especially key components such as the linear motion actuator 4, the first steel bar limiting and bending roller 6, and the second steel bar limiting and bending roller 7.

[0036] Insert the steel bar to be bent into the annular groove between the first steel bar limiting and bending roller 6 and the second steel bar limiting and bending roller 7, ensuring that the steel bar is stable and centered.

[0037] Start the linear motion actuator 4. The linear motion actuator 4 can be a hydraulic cylinder or an electric push rod. Through its telescopic function, the first steel bar limiting and bending roller 6 is moved, thereby adjusting the curvature of the steel bar according to requirements. When the steel bar reaches the expected curvature, stop the linear motion actuator 4 and take out the bent steel bar from the equipment.

[0038] When adjusting the second steel bar limiting and bending roller 7: Locate the fixed frame 9 at the rear end of the side frame 2 and identify the adjusting screw 11 passing through the fixed frame 9.

[0039] Use an appropriate tool (such as a screwdriver or wrench) to gently rotate the adjusting screw 11 to make its threaded connection with the fixed frame 9, thereby adjusting the extended length of the support shaft 8.

[0040] Since the adjusting screw 11 is connected to the support shaft 8 of the second steel bar limiting and bending roller 7, by rotating the adjusting screw 11, the position of the support shaft 8 inside the fixed frame 9 can be changed, thereby adjusting the distance between the second steel bar limiting and bending roller 7 and the first steel bar limiting and bending roller 6.

[0041] When the second steel bar limiting and bending roller 7 reaches the required position, ensure that the second steel bar limiting and bending roller 7 is stable and does not move.

[0042] After the adjustment is completed, a steel bar can be inserted for a trial bend to check whether the position of the second steel bar limiting and bending roller 7 is appropriate and whether it can cooperate with the first steel bar limiting and bending roller 6 to achieve the expected bending effect.

[0043] All the standard parts used in the present utility model can be purchased from the market. The special-shaped parts can be customized according to the descriptions in the specification and the attached drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding, which are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art. In addition, the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
