Description

Technical Field

[0001] This utility model relates to the field of H-beam processing technology, and in particular to an H-beam straightening machine. Background Technology

[0002] H-beams, a widely used building material, are named for their "H"-shaped cross-section. With their high strength, light weight, and ease of construction, they occupy an important position in various fields such as building structures, bridge construction, and industrial plants. As a key component of steel structures, their quality and straightening effect have a decisive impact on the safety and stability of the overall project. Especially in the core stage of steel structure manufacturing, the straightness and dimensional accuracy of H-beams directly affect the quality of the final structure. Therefore, effective straightening treatment is an essential step in the production of H-beams.

[0003] Specifically, existing H-beam straightening machines have gradually revealed a series of significant limitations and technical problems when straightening H-beams, especially when dealing with unevenness or deformation of the inner walls. Current straightening equipment often focuses only on adjusting the external contour, neglecting effective straightening of the inner walls. This not only greatly reduces the convenience of H-beam straightening but also significantly diminishes the overall straightening effect. These problems directly lead to reduced straightening efficiency and increased operational complexity, making it difficult to meet the production demands for high precision and specific requirements. Therefore, there is an urgent need for an H-beam straightening machine to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide an H-beam straightening machine that solves the problem that existing straightening equipment often only focuses on adjusting the external contour and is not convenient for effectively straightening the inner wall of the H-beam. This not only greatly reduces the convenience of H-beam straightening, but also significantly reduces the overall effect of H-beam straightening.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An H-beam straightening machine includes a frame, with several rollers rotatably connected to the inner side of the frame. A top plate is fixedly connected to the top of the frame, and a hydraulic pipe is embedded in the top plate. A top frame is fixedly connected to the top of the top plate, and a hydraulic cylinder is fixedly connected to one side of the top of the top frame by bolts. The output shaft of the hydraulic cylinder passes through the top of the top frame and the top of the hydraulic pipe and is fixedly connected to the top of a second piston. Piston tubes are connected to both sides of the bottom of the hydraulic pipe, and a first piston is provided inside each of the two piston tubes. A piston rod is fixedly connected to one side of each of the two first pistons. An extrusion plate is provided on one side of each of the two piston tubes, and one end of each piston rod passes through one side of each of the two piston tubes and is fixedly connected to one side of each of the two extrusion plates.

[0007] Preferably, pulleys are fixedly connected to one side of the inner side of each of the two piston tubes, and pull ropes are fixedly connected to one side of each of the two first pistons. One end of each pull rope passes through the two pulleys, and the extension ends of each pull rope are fixedly connected to the bottom of the second piston.

[0008] Preferably, the connections between the two piston rods and the two piston tubes are sliding connections, and the connections between the output shaft of the hydraulic cylinder and the hydraulic tubes are also sliding connections.

[0009] Preferably, a side plate is fixedly connected to one side of the frame, and a hydraulic cylinder is fixedly connected to one side of the side plate by bolts. A push plate is slidably connected to one side of the inner side of the frame, wherein the output shaft of the hydraulic cylinder passes through and is fixedly connected between one side of the side plate and the push plate.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Reference Figure 1-5 An H-beam straightening machine includes a frame 1, with several rollers 13 rotatably connected to the inner side of the frame 1. A top plate 7 is fixedly connected to the top of the frame 1, and a hydraulic pipe 10 is embedded in the top plate 7. A top frame 8 is fixedly connected to the top of the top plate 7, and a hydraulic cylinder 9 is fixedly connected to one side of the top of the top frame 8 by bolts. The output shaft of the hydraulic cylinder 9 passes through the top of the top frame 8 and the top of the hydraulic pipe 10 and is fixedly connected to the top of the second piston 18. Piston pipes 11 are connected to both sides of the bottom of the hydraulic pipe 10, and a first piston 14 is provided on the inner side of each of the two piston pipes 11. A piston rod 15 is fixedly connected to one side of each of the two first pistons 14. A pressing plate 12 is provided on one side of each of the two piston pipes 11, and one end of each piston rod 15 passes through one side of each of the two piston pipes 11 and is fixedly connected to one side of each of the two pressing plates 12.

[0023] First, a certain amount of hydraulic oil needs to be injected into the hydraulic pipe 10, ensuring that the hydraulic oil is positioned between the first piston 14 and the second piston 18. Then, the H-beam to be straightened is placed inside the frame 1, and its position is adjusted so that the two extrusion plates 12 are accurately positioned inside the H-beam and aligned with the required straightening position. After starting the equipment, the hydraulic cylinder 9 begins to work, driving the second piston 18 downwards. The pressure of the hydraulic oil acts on the two first pistons 14, thereby pushing the piston rod 15 outwards. This causes the extrusion plate 12, connected to one end of the piston rod 15, to apply pressure to the inner wall of the H-beam, effectively straightening any uneven or deformed parts of the H-beam's inner wall. Once one position is straightened, the hydraulic cylinder 9 drives the second piston 18 upwards, causing the extrusion plate 12 to retract, facilitating the straightening work for the next position. Throughout the process, the roller 13 assists in the positioning and movement of the H-beam, ensuring that each straightening operation is precisely applied to the required position.

[0024] Furthermore, pulleys 17 are fixedly connected to one side of the inner side of each of the two piston tubes 11, and pull ropes 16 are fixedly connected to one side of each of the two first pistons 14. One end of each pull rope 16 passes through the two pulleys 17, and the extension ends of each pull rope 16 are fixedly connected to the bottom of the second piston 18. When the second piston 18 moves up and down, the cooperation of the pull ropes 16 and pulleys 17 can drive the two first pistons 14 to move synchronously more smoothly. This not only improves the stability of the hydraulic system, but also ensures that the pressure applied by the two extrusion plates 12 to the inner wall of the H-beam is uniform and consistent, thereby improving the straightening accuracy and effect.

[0025] Furthermore, the connections between the two piston rods 15 and the two piston tubes 11 are both sliding connections, and the connection between the output shaft of the hydraulic cylinder 9 and the hydraulic tube 10 is also a sliding connection.

[0026] Furthermore, a side plate 3 is fixedly connected to one side of the frame 1, and a hydraulic cylinder 4 is fixedly connected to one side of the side plate 3 by bolts. A push plate 2 is slidably connected to the inner side of the frame 1. The output shaft of the hydraulic cylinder 4 passes through the side plate 3 and is fixedly connected to one side of the push plate 2. The hydraulic cylinder 4 pushes the push plate 2 to move the H-beam, which facilitates the straightening work of the H-beam at different positions.

[0027] Furthermore, sliders 5 are fixedly connected to both sides of the push plate 2, and both sliders 5 are slidably connected to the inner wall of the frame 1 through the slide groove 6, which realizes the smooth sliding of the push plate 2 inside the frame 1. This not only enhances the moving accuracy of the push plate 2, but also effectively avoids jamming or tilting problems caused by uneven force.

[0028] Furthermore, both ends of all rollers 13 are rotatably connected to the inner wall of the frame 1 via a pivot.

[0029] In summary:

[0030] First, a certain amount of hydraulic oil needs to be injected into the hydraulic pipe 10, ensuring that the hydraulic oil is positioned between the first piston 14 and the second piston 18. Then, the H-beam to be straightened is placed inside the frame 1, and its position is adjusted so that the two extrusion plates 12 are accurately positioned inside the H-beam and aligned with the required straightening position. After starting the equipment, the hydraulic cylinder 9 begins to work, driving the second piston 18 downwards. The pressure of the hydraulic oil acts on the two first pistons 14, thereby pushing the piston rod 15 outwards. This causes the extrusion plate 12, connected to one end of the piston rod 15, to apply pressure to the inner wall of the H-beam, effectively straightening any uneven or deformed parts of the H-beam's inner wall. Once one position is straightened, the hydraulic cylinder 9 drives the second piston 18 upwards, causing the extrusion plate 12 to retract, facilitating the straightening work for the next position. Throughout the process, the roller 13 assists in the positioning and movement of the H-beam, ensuring that each straightening operation is precisely applied to the required position. Furthermore, pulleys 17 are fixedly connected to one side of the inner side of each of the two piston tubes 11, and pull ropes 16 are fixedly connected to one side of each of the two first pistons 14. One end of each pull rope 16 passes through the two pulleys 17, and the extension ends of each pull rope 16 are fixedly connected to the bottom of the second piston 18. When the second piston 18 moves up and down, the cooperation of the pull ropes 16 and pulleys 17 can more smoothly drive the two first pistons 14 to move synchronously. This not only improves the stability of the hydraulic system but also ensures that the pressure applied by the two extrusion plates 12 to the inner wall of the H-beam is uniform, thereby improving the straightening accuracy and effect. In addition, the connection points between the two piston rods 15 and the two piston tubes 11 are all sliding connections, and the connection points between the output shaft of the hydraulic cylinder 9 and the hydraulic pipe 10 are also sliding connections. In actual operation, this design can effectively reduce the friction between components and ensure a smoother movement process. A side plate 3 is fixedly connected to one side of the frame 1, and a hydraulic cylinder 4 is bolted to one side of the side plate 3. A push plate 2 is slidably connected to the inner side of the frame 1. The output shaft of the hydraulic cylinder 4 passes through the side plate 3 and is fixedly connected to one side of the push plate 2. The hydraulic cylinder 4 pushes the push plate 2 to move the H-beam, facilitating the straightening of the H-beam at different positions. Slider 5 is fixedly connected to both sides of the push plate 2, and both sliders 5 are slidably connected to the inner wall of the frame 1 through a sliding groove 6. This achieves smooth sliding of the push plate 2 inside the frame 1, which not only enhances the moving accuracy of the push plate 2, but also effectively avoids jamming or tilting problems caused by uneven force. Both ends of all rollers 13 are rotatably connected to the inner wall of the frame 1 through a rotating shaft. This helps to reduce the frictional resistance of the H-beam inside the frame 1 and facilitates its position adjustment. By employing components such as hydraulic cylinder 9, hydraulic pipe 10, first piston 14 and second piston 18, as well as the setting of pull rope 16 and pulley 17, not only is the stability and response speed of the hydraulic system improved, but also the pressure applied by the two extrusion plates 12 to the inner wall of the H-beam is uniform and consistent, thereby improving the straightening accuracy and effect.Meanwhile, the sliding connection design between the piston rod 15 and the piston tube 11 reduces friction between components, extends the service life of the equipment, and improves work efficiency. The cooperative design of the hydraulic cylinder 4 and the push plate 2 allows the H-beam to be easily moved and positioned during the straightening process, improving operational convenience. The design of the sliders 5 and grooves 6 on both sides of the push plate 2 further enhances the moving accuracy and stability of the push plate 2, preventing jamming or tilting caused by uneven force. Finally, the rotating connection design of the roller 13 reduces the frictional resistance of the H-beam within the frame 1, making it easier to adjust its position and ensuring that each straightening operation is precisely applied to the required location. These improvements work together to overcome the limitations of traditional straightening equipment that can only adjust the external contour, and greatly improve straightening efficiency and quality.
