[0064] And, as Figure 4As shown, the locking limit hole 413 includes a first locking hole 4131 located above the first fixing rod 4421, a second locking hole 4132 located between the first fixing rod 4421 and the second fixing rod 4422 and communicating with the first locking hole 4131, a third locking hole 4133 located below the second fixing rod 4422 and communicating with the second locking hole 4132, and a fourth locking hole 4134 located below the third locking hole 4133 and communicating with the third locking hole 4133;

[0065] The fixed locking rod 443 includes a first locking rod 4431 inserted into the first locking hole 4131 and threadedly engaged with the transverse support plate assembly 41 and the first fixing rod 4421 respectively, a second locking rod 4432 connected to the first locking rod 4431 and inserted into the second locking hole 4132, a third locking rod 4433 connected to the second locking rod 4432 and inserted into the third locking hole 4133, and a fourth locking rod 4434 connected to the third locking rod 4433 and inserted into the fourth locking hole 4134; the second locking rod 4432 is threadedly engaged with the transverse support plate assembly 41 and the second fixing rod 4422 respectively, and the fourth locking rod 4434 is threadedly engaged with the transverse support plate assembly 41.

[0066] The first locking hole 4131, the second locking hole 4132, the third locking hole 4133 and the fourth locking hole 4134 which are sequentially communicated in this application form a through vertical locking channel; the first locking rod 4431 is threadedly engaged with the transverse support plate assembly 41 and the first fixing rod 4421 respectively, playing a role in fastening the upper limit structure. The second locking rod 4432 is threadedly engaged with the transverse support plate assembly 41 and the second fixing rod 4422 to achieve stable positioning in the middle. The third locking rod 4433 is inserted into the third locking hole 4133 to further enhance the integrity of the overall longitudinal locking. The fourth locking rod 4434 is threadedly engaged with the transverse support plate assembly 41 to complete the fixation at the lowermost side. This application realizes multi-point linkage fastening from top to bottom through multiple threaded engagement parts, so that the axial positions of the first fixing rod 4421 and the second fixing rod 4422 are firmly controlled in the multi-layer structure, preventing loosening or deviation during the correction process, ensuring the stable and reliable sliding limit position of the correction plate body 422, and improving the structural strength and use safety of the correction device under high-stress operations.

[0067] Further, as Figure 4 shown, the aperture of the first locking hole 4131 is larger than the aperture of the second locking hole 4132, the aperture of the second locking hole 4132 is larger than the aperture of the third locking hole 4133, and the aperture of the third locking hole 4133 is larger than the aperture of the fourth locking hole 4134;

[0068] The diameter of the first locking rod 4431 is greater than that of the second locking rod 4432, the diameter of the second locking rod 4432 is greater than that of the third locking rod 4433, and the diameter of the third locking rod 4433 is greater than that of the fourth locking rod 4434.

[0069] In the above-mentioned structure of the present application where the aperture diameters gradually decrease from top to bottom and match the diameters of the locking rods, when the fixed locking rod 443 is inserted, it is in interference or thread fit with the first locking hole 4131 to the fourth locking hole 4134 in sequence. This not only realizes multi-stage positioning but also has a guiding effect from thick to thin during operation, effectively avoiding jamming and damage caused by misalignment or forced insertion, improving the assembly smoothness and use safety. At the same time, the gradually changing structure enhances the overall connection strength and tensile and shear resistance through the way of gradually closing, and can more firmly lock the position of the correction plate body 422 during the correction process, thereby further improving the structural stability and operation reliability of the flat steel correction device.

[0070] The present application also discloses that the aperture diameter of the tapered limit hole 4425 on the first fixing rod 4421 is greater than that of the tapered limit hole 4425 on the second fixing rod 4422.

[0071] During the actual assembly process of the present application, when the fixed locking rod 443 is inserted into the tapered limit hole 4425 from top to bottom in sequence, it first enters the tapered limit hole 4425 on the first fixing rod 4421 with a larger aperture diameter, which has a larger guiding space, thereby reducing the initial insertion force and improving the insertion accuracy. Subsequently, it gradually transitions to the tapered limit hole 4425 on the second fixing rod 4422 with a smaller aperture diameter to achieve a more tightly limited fixing effect. This structure uses the design of decreasing aperture diameters to provide a segmented limit fit from loose to tight, enabling the fixed locking rod 443 to have the assembly advantages of being first introduced and then stabilized during the insertion process, being both convenient for quick installation and enhancing the locking stability and anti-loosening ability, thereby effectively improving the structural reliability and use safety of the flat steel correction device under long-term and high-intensity operations.

[0072] Furthermore, as Figure 4 shown, the first fixing rod 4421 is also provided with a first tapered inclined surface 4426, and the second fixing rod 4422 is also provided with a second tapered inclined surface 4427;

[0073] The fixed locking rod 443 further includes a first tapered slope 4435 located between the first locking rod 4431 and the second locking rod 4432 and used for top pressure fit with the first tapered inclined surface 4426, and a second tapered slope 4436 provided between the second locking rod 4432 and the third locking rod 4433 and used for top pressure fit with the second tapered inclined surface 4427.

[0074] The first conical slope 4435 of the present application is used for press-fitting with the first conical inclined surface 4426, and the second conical slope 4436 is used for press-fitting with the second conical inclined surface 4427. During the locking process, the fixed locking rod 443 is inserted into the locking limit hole 413 in sequence. When the fixed locking rod 443 is threaded to a predetermined position, a wedge-type pressing effect is generated between the first conical slope 4435 and the first conical inclined surface 4426, and between the second conical slope 4436 and the second conical inclined surface 4427, forming a multi-stage inclined surface tight contact structure, which effectively improves the axial clamping force and anti-pull-out force during the locking process. At the same time, the present application can still maintain a stable locking state under vibration or thermal expansion and contraction environment, avoiding loosening and displacement of the correction plate mechanism 4, thereby ensuring the fixing effect and correction accuracy of each structural component during the flat steel correction process, and improving the structural stability and service life of the overall device.

[0075] Specifically, Figure 5 As shown, the present application also discloses a flat steel correction method, including a flat steel correction device, and further comprising the following steps:

[0076] S1: Adjust the first correction plate 42 and the second correction plate 43 to a preset distance, and fix the relative positions between the transverse support plate assembly 41 and the first correction plate 42 and the second correction plate 43 by fixing the limiting mechanism 44;

[0077] S2: causing the correction handle mechanism 1 and the telescopic rod mechanism 2 to rotate relative to each other, so as to adjust the elbow rod mechanism 3 to a preset length;

[0080] S5: By pressing and toggling the correction handle mechanism 1, the first correction plate 42 and the second correction plate 43 correct the deformed part of the flat steel to achieve the flatness of the flat steel.

[0081] In this application, first, the positions of the first correction plate 42 and the second correction plate 43 in the transverse sliding groove 411 are adjusted, and the preset distance between the first correction plate 42 and the second correction plate 43 is locked by the fixed limiting mechanism 44 to ensure the stability of the correction distance; the correction handle mechanism 1 is rotated to drive the telescopic rod mechanism 2 that is in threaded cooperation with the correction handle mechanism 1 to move, and the telescopic rod mechanism 2 drives the elbow rod mechanism 3 to move to adjust the correction length of the flat steel; then the deformed flat steel is inserted between the first correction plate 42 and the second correction plate 43, and the electric heating sheet assembly 53 is attached to and heats the deformed part of the flat steel through the universal joint bamboo tube 52 to soften the deformed part of the flat steel; the correction handle mechanism 1 is pressed, and the first correction plate 42 and the second correction plate 43 are driven by the elbow rod mechanism 3 to apply a clamping and shaping force to the deformed part to complete the deformation correction and restore the flatness of the flat steel; this application combines an adjustment structure, local heating, and mechanical correction, with simple operation and high correction accuracy, which can improve the repair efficiency and finished product rate of the deformed flat steel, reduce manual errors, and improve process consistency.

[0082] The implementation principle of a flat steel correction device and a correction method according to an embodiment of this application is as follows:

[0083] A flat steel correction device rotates the correction handle mechanism 1 to make the telescopic rod mechanism 2 that is in threaded cooperation with the correction handle mechanism 1 advance or retreat, thereby driving the elbow rod mechanism 3 and the correction plate mechanism 4 to move to adjust the distance between the correction handle mechanism 1 and the area to be corrected for the flat steel. The heating sheet mechanism 5 extends along either side of the correction plate mechanism 4 and is used to attach to the flat steel correction area to heat and soften the local deformation area of the flat steel, which helps to improve the correction efficiency and correction quality; the first correction plate 42 and the second correction plate 43 are connected to the transverse support plate assembly 41 in a sliding connection manner, and the correction contact surface can be flexibly adjusted according to the deformation width of the flat steel. The fixed limiting mechanism 44 provided on the transverse support plate assembly 41 is used to fix the relative positions of the first correction plate 42 and the second correction plate 43 after the adjustment to prevent sliding and displacement, so as to achieve stable clamping and efficient correction of the deformed areas of flat steels with different widths; this application realizes collaborative correction through mechanical propulsion, heat softening, and sliding cooperation, with convenient operation, improving the correction efficiency and correction adaptability;

[0084] The first locking hole 4131, the second locking hole 4132, the third locking hole 4133, and the fourth locking hole 4134 are connected in sequence to form a through vertical locking channel; the first locking rod 4431 is threadedly engaged with the transverse support plate assembly 41 and the first fixing rod 4421 respectively, playing a role in fastening the upper limiting structure. The second locking rod 4432 is threadedly engaged with the transverse support plate assembly 41 and the second fixing rod 4422 to achieve stable positioning in the middle. The third locking rod 4433 is inserted into the third locking hole 4133 to further enhance the integrity of the overall longitudinal locking. The fourth locking rod 4434 is threadedly engaged with the transverse support plate assembly 41 to complete the fixation at the lowermost side. In this application, multiple threaded engagement parts are used to achieve multi-point linkage fastening from top to bottom, making the axial positions of the first fixing rod 4421 and the second fixing rod 4422 firmly controlled in the multi-layer structure, preventing loosening or deviation during the correction process, ensuring the stable and reliable sliding limiting position of the correction plate body 422, and improving the structural strength and use safety of the correction device under high-stress operations;

[0085] A flat steel correction method. First, adjust the positions of the first correction plate 42 and the second correction plate 43 in the transverse sliding groove 411, and lock the preset distance between the first correction plate 42 and the second correction plate 43 through the fixed limiting mechanism 44 to ensure the stability of the correction distance. Rotate the correction handle mechanism 1 to drive the telescopic rod mechanism 2 that is threadedly engaged with the correction handle mechanism 1 to move, and the telescopic rod mechanism 2 drives the elbow rod mechanism 3 to move to adjust the correction length of the flat steel. Then insert the deformed flat steel into the first correction plate 42 and the second correction plate 43. The electric heating sheet assembly 53 is attached to and heats the deformed part of the flat steel through the universal joint bamboo tube 52 to soften the deformed part of the flat steel. Press the correction handle mechanism 1, and drive the first correction plate 42 and the second correction plate 43 to apply clamping and shaping forces to the deformed part through the elbow rod mechanism 3 to complete the deformation correction and restore the flatness of the flat steel. This application combines the adjustment structure, local heating, and mechanical correction, with simple operation and high correction accuracy, which can improve the repair efficiency and finished product rate of the deformed flat steel, reduce manual errors, and improve process consistency.
