Description

Technical Field

[0001] The utility model relates to the technical field of steel straightening devices, in particular to a rapid straightening device used for steel structure processing. Background Art

[0002] Fabricating steel structures involves converting steel into the desired components through cutting, forming, welding, and assembly. Steel structures are widely used in construction, bridge construction, and machinery manufacturing, offering advantages such as high strength, lightness, and durability. Surface treatment is also required during the fabrication process to enhance corrosion resistance and aesthetics, ensuring the safety and stability of the structure.

[0003] H-shaped steel holds a crucial position in fabricated steel structures, distinguishing itself through its economical cross-section profiles, optimized area allocation, and highly reasonable strength-to-weight ratio. Named for its cross-sectional shape resembling the English letter "H," H-shaped steel not only exhibits precise right-angle arrangement of its components, but also offers comprehensive performance advantages: exceptional bending resistance, ensuring structural stability in all directions; a simplified construction process, reducing both construction difficulty and construction cycle time; significant cost savings thanks to its efficient material utilization; and a lightweight structure, which contributes to the overall economic efficiency and flexibility of the building. Consequently, H-shaped steel has become an indispensable structural material in both civil and industrial construction, widely used in various building structures.

[0004] During the processing, H-shaped steel will often produce certain deformation due to the influence of external forces, welding and uneven heating, so it must be corrected.

[0005] Currently, existing H-beam correction technologies on the market mainly focus on adjusting its verticality and flatness, using various compression and correction devices to ensure the accuracy of the H-beam in these key dimensions. However, when the H-beam is improperly handled during production, transportation, or installation, resulting in compression deformation perpendicular to the flange direction, these traditional correction methods become inadequate. This compression deformation often causes the cross-sectional shape of the H-beam to distort, affecting the overall stability and load-bearing capacity of the structure. Utility Model Content

[0006] The purpose of the present utility model is to provide a rapid correction device for steel structure processing to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0008] Base comprises support, castor, and frame upper is provided with guide rail, and support and conveyer frames movable end contact site are provided with recoil spring, and castor is arranged on the pin of base bottom four, to carry mobile handler location.

[0009] When correcting H-shaped steel, the steel to be corrected is placed on the fixed table from one side of the fixed table, and the distance between the pressure roller and the steel wing of the H-shaped steel is adjusted. Generally, the pressure roller is pressed into the steel wing by about 7-10 cm, and the guide roller is adjusted to prevent the main drive wheel from being blocked during the transmission process; then the first motor and the three-phase motor are started. The three-phase motor drives the main drive wheel to rotate and drive the H-shaped steel to move, and the first motor provides the force required for the pressure roller to rotate. During the movement of the H-shaped steel, the pressure roller rolls and squeezes the steel wing, so that the bent part of the steel returns to its original shape under the action of the yield force, and during the movement of the H-shaped steel, it passes through the auxiliary correction component, which eliminates the compression deformation in the flange direction, thereby improving the correction efficiency.

[0010] Further improvements to the technical solution of the present utility model are that the auxiliary correction component includes an upper pressure plate and a lower pressure plate, and the upper pressure plate and the lower pressure plate are slidably and telescopically connected; the lower pressure plate is slidably connected to the slide rail; the upper end of the lower pressure plate is fixedly connected to a first cylinder, and the movable end of the first cylinder is fixedly connected to the upper pressure plate, and the upper pressure plate and the lower pressure plate are both L-shaped.

[0011] The above technical solution is adopted. In this solution, before correction, the height of the upper pressure plate is adjusted by the first cylinder to match the width between the H-section steel wings. During the movement of the steel, it will pass through the upper pressure plate, and the upper pressure plate will support and adjust the bent parts, so that the workpiece is extended to its original size to achieve the purpose of correction.

[0012] A further improvement of the technical solution of the utility model is that: a pad is fixedly provided on the movable frame, the pad is arranged perpendicular to the direction of the slide rail, and an opening for exposing the main transmission roller is opened in the center of the pad.

[0013] The above technical solution is adopted. In this solution, when thin steel is corrected, because the lower end of the steel is supported by the main transmission wheel, the steel is prone to bending during transportation. By setting a pad, the pad can play a supporting role and prevent the steel from bending.

[0014] A further improvement of the technical solution of the utility model is that a measuring ruler is provided on one side of the lower pressing plate facing outwards, the measuring ruler is slidably connected to the side of the lower pressing plate, and the measuring ruler can be removed from the lower pressing plate.

[0015] The above technical solution often requires multiple corrections when correcting steel, and measurement is required after each correction. Manual handheld measurement is prone to errors due to some subjective factors. By setting a sliding connection for the measuring ruler, when measurement is required, only the measuring ruler needs to be sliding to facilitate judgment, which is accurate and convenient.

[0016] A further improvement of the technical solution of the present utility model is that: the two ends of the rotating groove are fixedly connected to the fixed rod blocks, and the fixed rod blocks are rotatably connected to the screw rod; a screw hole is opened at the lower end of the pressure block, and the pressure block is threadedly connected to the screw rod through the screw hole; the other end of the screw rod is fixedly connected to the transmission shaft of the second motor, and the second motor is used to drive the screw rod to rotate.

[0017] By adopting the above technical solution, in this embodiment, the second motor drives the lead screw to rotate, so that the distance between the movable frames can be adjusted conveniently and quickly, thereby improving the efficiency during debugging.

[0018] A further improvement of the technical solution of the present utility model is that a retractable suspension beam is fixedly connected between the two movable frames, a second cylinder is symmetrically provided at the lower end of the retractable suspension beam, and a top plate is fixedly connected to the movable end of the second cylinder.

[0019] The above technical solution is adopted. In this solution, when some deformations are directed upward, the upper pressure plate and the lower pressure plate cannot be corrected; by setting a top plate and adjusting the distance between the top plate and the upper surface of the upper pressure plate through the second cylinder, the rigid wing is squeezed and corrected through the upper pressure plate and the top plate.

[0020] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0021] 1. The utility model provides a rapid correction device for steel structure processing. When correcting H-shaped steel, the steel to be corrected is placed on the fixed platform from one side of the fixed platform, and the distance between the pressure roller and the steel wing of the H-shaped steel is adjusted. Generally, the pressure roller is controlled to press into the steel wing by about 7-10 cm, and the guide roller is adjusted to prevent the main drive wheel from being blocked during the transmission process; then the first motor and the three-phase motor are started, and the three-phase motor drives the main drive wheel to rotate and drive the H-shaped steel to move, while the first motor provides the force required for the pressure roller to rotate. During the movement of the H-shaped steel, the pressure roller rolls and squeezes the steel wing of the steel, so that the bent part of the steel returns to its original shape under the action of the yield force, and during the movement of the H-shaped steel, it passes through the auxiliary correction component, which eliminates the compression deformation in the flange direction, thereby improving the correction efficiency.

[0022] 2. The utility model provides a rapid correction device for steel structure processing. The height of the upper pressure plate is adjusted by the first cylinder to conform to the width between the steel wings of the H-section. During the movement of the steel, it will pass through the upper pressure plate. If there is a bend, the upper pressure plate will support and adjust it, so that the workpiece is extended to its original size to achieve the purpose of correction.

[0023] 3. The utility model provides a rapid correction device for steel structure processing. When some deformations are directed upward, the upper and lower pressure plates cannot be corrected. By setting a top plate and adjusting the distance between the top plate and the upper surface of the upper pressure plate through the second cylinder, the steel wing is squeezed and corrected through the upper pressure plate and the top plate.

[0031] The present invention is further described in detail below with reference to the embodiments:

[0032] Example 1

[0033] like Figure 1-Figure 5 As shown, the utility model provides a rapid correction device for steel structure processing, comprising: a fixed platform 1 is fixedly connected to a slide rail 3, a mobile frame 2 is symmetrically provided on the slide rail 3, and the mobile frame 2 is slidably connected to the slide rail 3; two opposite sides of the two mobile frames 2 are symmetrically provided with pressure blocks 4, and symmetrical hydraulic cylinders 5 are provided on both sides of the pressure blocks 4, and the hydraulic cylinders 5 are fixedly connected to the mobile frame 2; a first motor 6 is provided on the mobile frame 2, and a pressure roller 8 is rotatably connected to one side of the pressure block 4, and the transmission end of the pressure roller 8 is connected to the rotating structure 7, and the rotating structure The structure 7 is used to convert the vertical rotational force of the first motor 6 into a horizontal rotational force; the movable end of the hydraulic cylinder 5 is fixedly connected to a guide roller 9 for guiding; a receiving platform 10 is fixedly connected to one side of the fixed platform 1, and a three-phase motor 11 is fixedly installed on the receiving platform 10. A rotating groove 12 is provided on the fixed platform 1, and a main transmission shaft 13 is provided in the rotating groove 12. A main transmission roller 14 is fixedly provided on the main transmission shaft 13, and the main transmission shaft 13 is fixedly connected to the output end of the three-phase motor 11; an auxiliary correction component is provided on the outward side of the guide roller 9.

[0034] In this embodiment, when correcting the H-steel, the steel to be corrected is placed on the fixed platform 1 from one side of the fixed platform 1, and the distance between the pressure roller 8 and the steel wing of the H-shaped steel is adjusted. Generally, the pressure roller 8 is controlled to press the steel wing into about 7-10 cm, and the guide roller 9 is adjusted to prevent the main drive wheel from being blocked during the transmission process; then the first motor 6 and the three-phase motor 11 are started, and the three-phase motor 11 drives the main drive wheel to rotate and drive the H-shaped steel to move, and the first motor 6 provides the force required for the rotation of the pressure roller 8 through the rotating structure 7 (the rotating structure is a higher-level concept and is not limited). During the movement of the H-shaped steel, the pressure roller 8 rolls and squeezes the steel wing, so that the bent part of the steel returns to its original state under the action of the yield force, and during the movement of the H-shaped steel, it passes through the auxiliary correction component, which eliminates the compression deformation in the flange direction, thereby improving the correction efficiency.

[0035] like Figure 1-3 As shown, in this embodiment, preferably, the auxiliary correction component includes an upper pressure plate 15 and a lower pressure plate 16, and the upper pressure plate 15 and the lower pressure plate 16 are slidably and telescopically connected; the lower pressure plate 16 is slidably connected to the slide rail 3; the upper end of the lower pressure plate 16 is fixedly connected to the first cylinder 17, and the movable end of the first cylinder 17 is fixedly connected to the upper pressure plate 15, and the upper pressure plate 15 and the lower pressure plate 16 are both L-shaped.

[0036] Before correction, the height of the upper pressing plate 15 is adjusted by the first cylinder 17 to match the width between the steel wings of the H-section. During the movement of the steel, it will pass through the upper pressing plate 15. If there is a bend, the upper pressing plate 15 will support and adjust it, so that the workpiece is extended to its original size to achieve the purpose of correction.

[0037] A pad 22 is fixedly provided on the movable frame 2 . The pad 22 is arranged perpendicular to the direction of the slide rail 3 . An opening for exposing the main transmission roller 14 is provided at the center of the pad 22 .

[0038] When thin steel is corrected, since the lower end of the steel is supported by the main transmission wheel, the steel is easily bent during transportation. By providing the pad 22, the pad 22 can play a supporting role and prevent the steel from bending.

[0039] A measuring ruler 23 is provided on one side of the lower pressing plate 16 facing outward. The measuring ruler 23 is slidably connected to the side surface of the lower pressing plate 16 and can be removed from the lower pressing plate 16 .

[0040] When correcting steel, it is often necessary to correct it multiple times, and measurement is required after each correction. Manual handheld measurement is prone to errors due to some subjective factors. By setting a sliding connection for the measuring ruler 23, when measurement is required, only the measuring ruler 23 needs to be slid to facilitate judgment, which is accurate and convenient.

[0042] like Figure 3 As shown, based on Example 1, the utility model provides a technical solution: preferably, the two ends of the rotating groove 12 are fixedly connected to the fixed rod block 18, and the fixed rod block 18 is rotatably connected to the screw rod 19; a screw hole is provided at the lower end of the pressure block 4, and the pressure block 4 is threadedly connected to the screw rod 19 through the screw hole; the other end of the screw rod 19 is fixedly connected to the second motor drive shaft, and the second motor is used to drive the screw rod 19 to rotate.

[0043] In this embodiment, the second motor drives the screw rod 19 to rotate, so that the distance between the movable frames 2 can be adjusted conveniently and quickly, thereby improving the efficiency of debugging.

[0046] In this embodiment, when some deformations are directed upward, the upper pressure plate 15 and the lower pressure plate 16 cannot be corrected; by setting the top plate 21, the distance between the top plate 21 and the upper surface of the upper pressure plate 15 is adjusted by the second cylinder, and the rigid wing is squeezed and corrected by the upper pressure plate 15 and the top plate 21.

[0047] The following is a detailed description of the working principle of the rapid correction device used for steel structure processing.

Generally, the pressure roller 8 is controlled to press the steel wing into about 7-10 cm, and the guide roller 9 is adjusted to prevent the main transmission wheel from being blocked during the transmission process; then the first motor 6 and the three-phase motor 11 are started, and the three-phase motor 11 drives the main transmission wheel to rotate and drive the H-shaped steel to move, while the first motor 6 provides the force required for the pressure roller 8 to rotate. During the movement of the H-shaped steel, the pressure roller 8 rolls and squeezes the steel wing, making the steel bend. The bent part returns to its original shape under the action of the yield force; before correction, the height of the upper pressure plate 15 is adjusted by the first cylinder 17 to match the width between the steel wings of the H-section. During the movement of the steel, it will pass through the upper pressure plate 15, and the upper pressure plate 15 will support and adjust the bent parts, so that the workpiece is extended to its original size; when some deformation is toward the upper part, the upper pressure plate 15 and the lower pressure plate 16 cannot be corrected; by setting the top plate 21, the distance between the top plate 21 and the upper surface of the upper pressure plate 15 is adjusted by the second cylinder, and the steel wings are squeezed and corrected by the upper pressure plate 15 and the top plate 21.

[0049] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
