Description

Technical Field

[0001] This utility model relates to the field of steel component processing technology, and in particular to a support fixture for processing H-shaped steel components. Background Technology

[0002] The fabrication of H-beams is a complex process involving multiple steps. Before cutting, the steel plates need to be pre-treated, including removing oxide layers, rust, oil, and other impurities from the surface to improve surface density and ensure subsequent welding quality. Raw materials must undergo re-inspection and testing according to standards and project technical requirements before warehousing and use; only qualified materials can be used for component production. Cutting and Leveling: Before cutting, a leveling machine is used to level the steel plates to ensure cutting accuracy. Cutting: A precision CNC flame steel plate cutting machine or a flame multi-head straight bar cutting machine is used for cutting. During cutting, the material, specifications, and dimensions of the steel plates must be carefully checked for accuracy, and cutting tolerances and quality must meet relevant specifications. T-Shaped Assembly: On an automatic H-beam assembly machine, the web plate and one of the flange plates are assembled into a T-shape and positioned by welding. H-Shaped Assembly: The T-shape is assembled with another flange plate to form an H-shape, ensuring the perpendicularity of the flange plate to the web plate meets design requirements. After assembly, temporary fixation is achieved using additional process plates. Main weld welding: Welding the four main welds of the H-beam is a critical step. Before welding, impurities such as rust, burrs, oxides, and oil must be removed from the weld area. Automatic welding using a gantry submerged arc welding method is commonly employed to ensure weld quality. Welding quality control: During welding, the position of the welding wire should be observed and adjusted promptly to prevent wire deviation. After welding, weld quality inspection is required, including visual inspection and non-destructive testing, to ensure the weld quality meets design requirements. Mechanical straightening is then performed to eliminate stress and deformation generated during welding. Mechanical straightening is typically done using an H-beam flange straightening machine to ensure the parallelism of the flange plates and the perpendicularity of the flange plates to the web plates. For components with significant bending or torsional deformation, flame straightening can be used. Flame temperature must be controlled during straightening to avoid overheating. According to design requirements, mounting holes and interlocking seams are fabricated on the H-beam, and the welds are cleaned and ground to eliminate welding defects and excess weld weight. Flame straightening can be used for areas with significant localized deformation. H-beams are rust-removed by shot blasting to improve coating adhesion, and then coated to enhance their corrosion resistance and service life.

[0003] Supports play a crucial role in the fabrication of H-beams, ensuring their stability and safety during processing, transportation, and installation. Support devices secure the H-beams, preventing displacement or deformation due to vibration or external forces during fabrication, thus ensuring accuracy and stability. Providing robust support reduces the risk of accidents and protects operators. A well-designed support system simplifies the fabrication process, improves efficiency, and reduces production costs. For example, using specialized brackets or supports to fix the H-beams to the workbench is suitable for situations where movement of the H-beams is not required during fabrication. Using rollers or sliding devices to support the H-beams, allowing them to move along a specific path during fabrication, is suitable for situations requiring continuous fabrication or long-distance transport.

[0004] When processing H-beams, it is necessary to ensure their stability. However, the traditional method of supporting and fixing H-beams involves clamping them to the sides, top, or bottom with clamps. This method results in an excessively large contact area between the fixing components and the H-beams, making it difficult to process and hindering the processing of certain parts of the H-beams. Therefore, there is an urgent need for a support fixture for processing H-beams to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a support fixture for processing H-beam steel components. This solves the problem that in the prior art, when supporting and fixing H-beam steel components, clamps are used to hold and fix the sides, top, and bottom of the H-beam steel components. This fixing method results in an excessively large contact area between the fixing component and the H-beam steel component, which makes it inconvenient to process the H-beam steel component and hinders the processing of some parts of the H-beam steel component.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A support fixture for processing H-beam steel components includes a frame, a support plate slidably connected to the inner side of the frame, and a bearing plate fixedly connected to both sides of the top of the support plate. Adjustment plates are provided on both sides of the two bearing plates, with one end of each adjustment plate penetrating through the two bearing plates. A threaded rod is provided at the bottom of one end of each adjustment plate. A limit frame is rotatably connected to the bottom of each of the four threaded rods, and the top ends of each of the four threaded rods penetrate through the four adjustment plates. Insert rods are provided on both sides of the top of the two bearing plates, and slots for use with the insert rods are provided on the top of the bearing plates and one side of the top of the adjustment plates. Several slots are provided on the adjustment plates.

[0008] Preferably, sliders are fixedly connected to both sides of the support plate, and both sliders are slidably connected to the side wall of the frame through a groove.

[0009] Preferably, the bottom ends of the four threaded rods are all threadedly connected to the adjusting plate through threaded grooves.

[0010] Preferably, the bottom ends of the four threaded rods are rotatably connected to the tops of the four limiting frames via rotating shafts.

[0011] Preferably, each of the four adjusting plates has a pull plate fixedly connected to it on the side away from the four threaded rods, and each of the four pull plates has a handle fixedly connected to one side.

[0012] Preferably, the connection between the output shaft of the hydraulic cylinder and the frame is a sliding connection.

[0013] This utility model has the following beneficial effects:

[0014] The required H-beam steel component is placed on top of the support plate. Then, according to the specifications of the H-beam steel component, the positions of the four limiting frames are adjusted so that they are located at the four corners of the H-beam steel component. The adjusting plate is then limited by inserting the rod into the slot. The threaded rod is then continuously rotated, causing the limiting frames to move downwards, thus fitting the four limiting frames onto the four corners of the H-beam steel component. This effectively limits and fixes the four corners of the H-beam steel component, significantly reducing the contact area between the supporting limiting components and the H-beam steel component compared to existing technologies for supporting H-beam steel components. During fixing, clamps are typically used to hold and fix the H-beams on both sides or at the top and bottom. This method results in an excessively large contact area between the fixing components and the H-beams, making it difficult to process the H-beams and hindering processing in certain areas. The method proposed in this invention, through the coordinated use of various structures, limits and fixes the four corners of the H-beams. This not only ensures the stability of the H-beam support but also significantly reduces the contact area between the supporting limiting components and the H-beams, facilitating subsequent processing of the H-beams.

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.

[0023] Reference Figure 1-5 A support fixture for processing H-beam steel components includes a frame 1, a support plate 2 slidably connected to the inner side of the frame 1, and bearing plates 4 fixedly connected to the top two sides of the support plate 2. Adjustment plates 5 are provided on both sides of the two bearing plates 4. The movement of the adjustment plates 5 allows for the adjustment of a limiting frame 8. One end of each adjustment plate 5 passes through one of the two bearing plates 4, and a threaded rod 9 is provided at the bottom of one end of each adjustment plate 5. The bottom ends of the four threaded rods 9 are rotatably connected to the limiting frame 8. The limiting frame 8 can be adjusted at any time according to the required H-beam steel. The top ends of the four threaded rods 9 pass through the four adjustment plates 5. Insert rods 12 are provided on both sides of the top of the two bearing plates 4. Slots 13 for use with the insert rods 12 are provided on the top of the bearing plates 4 and one side of the top of the adjustment plates 5. Several slots 13 are provided on the adjustment plates 5. By engaging the insert rods 12 with the corresponding slots 13 on the top of the bearing plates 4 and the adjustment plates 5, the adjustment plates 5 can be limited.

[0024] Furthermore, sliders 10 are fixedly connected to both sides of the support plate 2, and both sliders 10 are slidably connected to the side wall of the frame 1 through the slide groove 11. By using the sliders 10 to slide in the slide groove 11, the stability of the support plate 2 can be greatly improved.

[0025] Furthermore, the bottom ends of the four threaded rods 9 are all threadedly connected to the adjusting plate 5 through the threaded grooves 14.

[0026] Furthermore, the bottom ends of the four threaded rods 9 are rotatably connected to the tops of the four limiting frames 8 via rotating shafts.

[0027] Furthermore, each of the four adjusting plates 5 has a pull plate 6 fixedly connected to one side away from the four threaded rods 9, and each of the four pull plates 6 has a handle 7 fixedly connected to one side. The adjusting plates 5 can be easily adjusted by pulling them out using either the handle 7 or the pull plate 6.

[0028] Furthermore, the connection between the output shaft of the hydraulic cylinder 3 and the frame 1 is a sliding connection.

[0029] In summary:

[0030] First, the operator needs to place the H-beam steel component to be processed stably on top of the support plate 2. Next, according to the specific specifications and dimensions of the H-beam steel component, the operator needs to finely adjust the positions of the four limiting frames 8. This adjustment process is achieved by pulling out the adjusting plate 5 on the tooling, which easily allows for slight movements of the limiting frames 8 in the horizontal and vertical directions. Through precise adjustment, the four limiting frames 8 can be accurately positioned at the four corners of the H-beam steel component, laying a solid foundation for subsequent limiting and fixing. After the positions of the limiting frames 8 are determined, the adjusting plate 5 is further limited by inserting the rod 12 into the slot 13. This design not only enhances the stability of the adjusting plate 5 but also ensures that the adjusting plate 5 will not shift due to external forces during the entire processing, thus guaranteeing processing accuracy and efficiency. Subsequently, the operator needs to manually rotate the four threaded rods 9. As the threaded rods 9 rotate continuously, they drive the limiting frames 8 to gradually move downwards. During this process, the operator can adjust the positions according to actual needs. By controlling the rotation speed and number of turns of the threaded rod 9, the downward movement distance of the limiting frame 8 is precisely controlled. When the limiting frame 8 is completely fitted into the four corners of the H-beam, the limiting and fixing of the H-beam is completed. This method of limiting and fixing the four corners of the H-beam has significant advantages. On the one hand, it ensures that the H-beam remains stable during processing and will not shake or tilt due to external forces, thus guaranteeing the quality and safety of processing. On the other hand, since the limiting frame 8 only contacts the four corners of the H-beam, the contact area between the supporting limiting component and the H-beam is greatly reduced. This not only reduces friction and resistance during processing but also makes subsequent processing of the H-beam more convenient and faster, improving processing efficiency and quality. Through its unique design and ingenious mechanism, it achieves efficient and stable support and limiting fixation of the H-beam, which not only provides strong support for the processing of H-beams but also lays a solid foundation for improving processing efficiency and quality.
