[0002] Light steel structure buildings have developed rapidly in China due to their fast construction speed, beautiful, fashionable and environmentally friendly appearance and color. H-shaped steel is an economical section steel with better section mechanical properties than I-beams. It is named because the shape of its section is the same as the English letter "H". During the production process of H-shaped steel, due to the existence of welding stress, excessive or too small restraint will cause the H-shaped steel to deform. Therefore, a straightening machine is needed to straighten the H-shaped steel.

[0003] After retrieval, a Chinese patent discloses an H-shaped steel processing device (publication number: CN216857833U). Although the lower straightening structure and the upper straightening structure support the inner sides of the two web plates, and the web plates experience the processes of straightening, heating, secondary straightening and cooling in turn during the movement of the H-shaped steel, so as to achieve the purpose of straightening the web plates. No matter how large the deformation of the H-shaped steel is, it has a good straightening effect. However, when the four heating heads and the four cooling heads heat and cool the H-shaped steel, they are heated as a whole, and the temperature required for straightening is relatively high, and the required energy is relatively high. It cannot perform fixed-point heating and straightening according to the deformation position. Therefore, the technical personnel in this field provide a straightening device for H-shaped steel structure processing to solve the problems raised in the above background technique.

The H-shaped steel is supported by the two guide structures 9 to prevent the length of the H-shaped steel from being too long, resulting in unstable clamping of the two connecting seats 5 to the H-shaped steel and causing accidents.

[0033] The correction structure 10 includes a baffle 1001, two correction plates 1003, multiple correction rollers 1004, multiple cooling heads 1005, two first substrates 1006, multiple heating heads 1007, two second substrates 1008, two third substrates 1009, multiple delay-off switches 1010, multiple springs 1011 and multiple pressing rollers 1012. The two third substrates 1009 are arranged side by side at a position close to the front of one side of the baffle 1001. The multiple delay-off switches 1010 are arranged in a rectangular pattern on one side wall of the two third substrates 1009.

Multiple groups of delay-off switches 1010 are electrically connected between multiple groups of heating heads 1007 and multiple groups of cooling heads 1005 respectively. When the deformed H-shaped steel touches the multiple pressing rollers 1012 and moves to one side, the delay-off switches 1010 are pressed, so that the multiple heating heads 1007 and the multiple cooling heads 1005 at the corresponding positions are started, and the deformed position is subjected to fixed-point heating correction and cooling, reducing the energy consumption of the overall heating.

[0034] The guiding structure 9 includes a bottom plate 901 and multiple guiding rollers 902. The multiple guiding rollers 902 are arranged in the front and back at the center of the upper end surface of the bottom plate 901, which is convenient for preventing the H-shaped steel from being too long before and after correction, resulting in unstable clamping of the H-shaped steel by the two connecting seats 5 and causing accidents.

[0035] A plurality of hydraulic rods 1002 are arranged in the front and back at the center of one side wall of the four baffles 1001 and at the center of the two side walls of the two bases 4. The output ends of the plurality of hydraulic rods 1002 are respectively fixedly connected to one side wall of eight third substrates 1009, one side wall of eight second substrates 1008, one side wall of eight correction plates 1003, and one side wall of eight first substrates 1006. By pushing the eight third substrates 1009, eight second substrates 1008, eight correction plates 1003, and eight first substrates 1006 with the plurality of hydraulic rods 1002 to fit on the H-shaped steel for correction. A plurality of delay-off switches 1010, a plurality of heating heads 1007, and a plurality of cooling heads 1005 are arranged in the front and back as a group. Multiple groups of delay-off switches 1010 are electrically connected between multiple groups of heating heads 1007 and multiple groups of cooling heads 1005 respectively. The corresponding delay-off switches 1010 are used to control the start and delay stop of the multiple groups of heating heads 1007 and cooling heads 1005 at the corresponding positions, reducing energy consumption. One side wall of each of the eight correction plates 1003 is provided with an inclined surface, which facilitates the correction rollers 1004 on the inclined surface to pre-correct the H-shaped steel.

[0036] The output ends of the two motors 3 respectively penetrate one side wall of the two connecting seats 5 and are fixedly connected between the two front rollers 11. By driving the two front rollers 11 to rotate with the two motors 3, the H-shaped steel is transported backward. The heights of the four third substrates 1009, four second substrates 1008, four correction plates 1003, and four first substrates 1006 on the outer side are higher than those of the four third substrates 1009, four second substrates 1008, four correction plates 1003, and four first substrates 1006 on the inner side, which is convenient for comprehensively correcting the H-shaped steel.

[0037] Working principle: When in use, place the H-beam on the front bottom plate 901. Support the H-beam through multiple guide rollers 902 added on the two bottom plates 901 to prevent accidents caused by the excessive length of the H-beam, resulting in unstable clamping of the H-beam by the two connecting seats 5. Place the end of the H-beam between the two connecting seats 5, and multiple second electric telescopic rods 12 clamp the H-beam. Then start the contraction of the four first electric telescopic rods 6, and the eight third base plates 1009, eight second base plates 1008, eight correction plates 1003 and eight first base plates 1006 surround the H-beam completely. Start the two motors 3, and the two motors 3 drive the two front rollers 11 to rotate to convey the H-beam backward. When the deformed H-beam touches the multiple pressing rollers 1012 and moves to one side, the pressing delay-off switch 1010 is triggered, so that the multiple heating heads 1007 and multiple cooling heads 1005 at the corresponding positions are started to perform fixed-point heating correction and cooling on the deformed position, reducing the energy consumption of overall heating. Since the one side wall of each of the eight correction plates 1003 is provided with an inclined surface, correction rollers 1004 are added on the inclined surface and the correction plates 1003 for correction. The correction rollers 1004 on the inclined surface first perform pre-correction on the H-beam, then perform correction at the rear end, and then roll between the multiple correction rollers 1004 and the H-beam to reduce the friction with the H-beam and reduce the damage to the H-beam.
