[0065] The fixed locking rod 443 includes a first locking rod 4431 inserted in the first locking hole 4131 and threadedly engaged with the transverse support plate assembly 41 and the first fixed rod 4421 respectively, a second locking rod 4432 connected to the first locking rod 4431 and inserted in the second locking hole 4132, a third locking rod 4433 connected to the second locking rod 4432 and inserted in the third locking hole 4133, and a fourth locking rod 4434 connected to the third locking rod 4433 and inserted in the fourth locking hole 4134; the second locking rod 4432 is threadedly engaged with the transverse support plate assembly 41 and the second fixed 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 are connected in sequence in the present application to form a vertical locking channel running through; the first locking rod 4431 is threadedly engaged with the transverse support plate assembly 41 and the first fixing rod 4421 respectively, and plays 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 41 33, the integrity of the overall longitudinal locking is further enhanced, and the fourth locking rod 4434 is threadedly engaged with the transverse support plate assembly 41 to complete the fixation of the lower side. The present application realizes multi-point linkage fastening from top to bottom through multiple threaded engagement parts, so that the axial position of the first fixing rod 4421 and the second fixing rod 4422 in the multi-layer structure is firmly controlled to prevent loosening or displacement during the correction process, ensuring that the sliding limit position of the correction plate body 422 is stable and reliable, thereby improving the structural strength and safety of the correction device under high-stress operation.

[0067] Furthermore, if Figure 4 As 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 larger than that of the second locking rod 4432 . The diameter of the second locking rod 4432 is larger than that of the third locking rod 4433 . The diameter of the third locking rod 4433 is larger than that of the fourth locking rod 4434 .

[0069] The above-mentioned structure of the aperture and locking rod diameter that decrease step by step from top to bottom in the present application enables the fixed locking rod 443 to be interference fit or threaded in the first locking hole 4131 to the fourth locking hole 4134 in sequence during the insertion process, which not only realizes multi-level positioning, but also has a coarse to fine guiding effect during operation, effectively avoiding jamming and damage caused by misalignment or forced insertion, improving assembly smoothness and safety of use. At the same time, the gradual structure enhances the overall connection strength and tensile and shear resistance through step-by-step sealing, and can more firmly lock the position of the correction plate body 422 during the correction process, thereby further improving the structural stability and operational reliability of the flat steel correction device.

[0070] The present application also discloses that the diameter of the tapered limiting hole 4425 on the first fixing rod 4421 is larger than the diameter of the tapered limiting 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 conical limiting hole 4425 from top to bottom, it first enters the conical limiting hole 4425 on the first fixed rod 4421 with a larger aperture, which has a larger guiding space, thereby reducing the initial insertion force and improving the insertion accuracy, and then gradually transitions to the conical limiting hole 4425 on the second fixed rod 4422 with a smaller aperture, to achieve a tighter limiting and fixing effect. The structure uses a decreasing aperture design to provide a segmented limiting fit from loose to tight, so that the fixed locking rod 443 has the assembly advantage of first introduction and then stabilization during the insertion process, which is convenient and quick to install, and enhances 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, high-intensity operation.

[0072] Furthermore, if Figure 4 As shown, the first fixing rod 4421 is further provided with a first conical inclined surface 4426, and the second fixing rod 4422 is further provided with a second conical inclined surface 4427;

[0073] The fixed locking rod 443 also includes a first conical slope 4435 located between the first locking rod 4431 and the second locking rod 4432 and used to press-fit with the first conical inclined surface 4426, and a second conical slope 4436 located between the second locking rod 4432 and the third locking rod 4433 and used to press-fit with the second conical inclined surface 4427.

[0074] The first conical slope 4435 of the present application is used to press-fit with the first conical inclined surface 4426, and the second conical slope 4436 is used to press-fit 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 the 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 compression 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.

[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 portion of the flat steel to achieve the flatness of the flat steel.

[0081] The present application first adjusts the position of the first correction plate 42 and the second correction plate 43 in the horizontal slide groove 411, and locks the preset distance between the first correction plate 42 and the second correction plate 43 through the fixed limit mechanism 44 to ensure that the correction distance is stable; rotates the correction handle mechanism 1 to drive the telescopic rod mechanism 2 threadedly matched 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 inserts the deformed flat steel into the first correction plate 42 and the second correction plate 43, and the electric heating plate assembly 53 is pressed against and heats the deformed part of the flat steel through the universal bamboo tube 52 to soften the deformed part of the flat steel; presses the correction handle mechanism 1, and drives the first correction plate 42 and the second correction plate 43 through the elbow rod mechanism 3 to apply clamping and shaping force to the deformed part to complete the deformation correction and realize the flatness restoration of the flat steel; the present application combines the adjustment structure, local heating and mechanical correction, is easy to operate, and has high correction accuracy, which can improve the repair efficiency and yield rate of deformed flat steel, reduce manual errors and improve process consistency.
