[0051] Wing 201 Detailed implementation method:

[0052] T-shaped profiles consist of a web and flanges. The web is welded below the flanges to form a T-shaped cross-section. This is a major structural component in many structures and rails, and is also widely used in the shipbuilding industry. The lower edge of the web in the middle of the T-shape is welded to the base surface. During the welding process, the upper flange is in a horizontal state. The entire profile can serve as a rail or a base frame. Whether it is a rail or a base frame, it is used as a reference. Therefore, the T-shaped profile must not have any deformation that does not meet the precision requirements. In particular, the upper end face of the T-shaped profile needs to ensure its flatness. However, during the welding process, especially during long-distance welding, deformation may occur, that is, the flatness of the upper end face of the flange does not meet the flatness requirements.

[0053] Figure 1 This is a three-dimensional schematic diagram of a straightening device for a type of steel profile according to an embodiment of the present invention; Figure 2 This is a front view schematic diagram of a steel straightening device according to another embodiment of the present invention; Figure 3 This is a top view schematic diagram of a steel straightening device according to another embodiment of the present invention; Figure 4 This is a side view of a straightening device for steel profiles according to another embodiment of the present invention; Figure 5 This is a schematic diagram of a straightening device for a steel profile and a T-shaped profile according to another embodiment of the present invention. Figures 1 to 5 As shown, in one embodiment, the present invention provides a straightening device for steel profiles, the straightening device for steel profiles includes at least a pair of channel steels 1 and at least one connecting strip 2, as well as a first bolt 3, a second bolt 4, a third bolt 5, and a fourth bolt 6;

[0054] The channel steel 1 is arranged in pairs, facing the same direction, with the openings 11 of the pairs of channel steel 1 facing each other.

[0055] The connecting strip 2 has a first end face 21, which is attached to the same outer end face 12 of the paired channel steel 1, and both ends of the connecting strip 2 are respectively fixed on the paired channel steel 1.

[0056] The first bolt 3 and the second bolt 4 penetrate from the outer end face 22 into the interior of the channel steel 1;

[0057] The third bolt 5 and the fourth bolt 6 are fixed to the paired channel steel 1 by passing nuts through them.

[0058] This embodiment provides a specific structure for a steel profile straightening device. Channel steels 1 are arranged in pairs, with the openings 11 of each channel steel 1 facing each other. The two sides of the flange of the T-shaped profile are respectively placed inside the paired channel steels 1. The lower end face inside the channel steel 1 serves as a reference. Because the steel profile straightening device is not welded, it can ensure that it will not undergo thermal deformation. The symmetrical channel steels 1 can be connected by connecting strips 2 to ensure that their lower end faces are in the same plane and overlap the lower end face of the flange. After adjusting the third bolt 5 and the fourth bolt 6 to level the lower end face, the first bolt 3 and the second bolt 4, with their inserted ends pressing against the two sides of the flange, can be used to correct the flatness of the upper end face of the flange. This helps to solve the technical problem of lacking a steel profile straightening device in the prior art for straightening T-shaped steel after welding.

[0059] In one embodiment, the connecting strip 2 is provided with an elongated hole 22 along its length direction, and the connecting strip 2 is fixed to a pair of channel steels 1 through the elongated hole 22 by the fifth bolt 7 and the sixth bolt 8.

[0060] This embodiment provides a specific structure for a connecting strip 2, in which an elongated hole 22 is provided in the middle to adjust the distance between the channel steel 1 by means of the fifth bolt 7 and the sixth bolt 8, so as to meet the leveling requirements of different T-shaped profiles.

[0061] In one embodiment, the straightening device for the steel profile further includes a seventh bolt 9 and an eighth bolt 10, which are fixed to one end of the pair of channel steels 1 after being threaded through with nuts, and a third bolt 5 and a fourth bolt 6 are fixed to the other end of the pair of channel steels 1 after being threaded through with nuts.

[0062] In this embodiment, a seventh bolt 9 and an eighth bolt 10, a third bolt 5 and a fourth bolt 6 are provided to form a surface adjustment around the channel steel 1 pair, which can better adjust and help the flatness of the T-profile, and the channel steel 1 pair is also better subjected to force.

[0063] In one embodiment, there are two connecting strips 2, which are respectively disposed at both ends of the channel steel 1.

[0064] This embodiment provides a specific implementation where there are two connecting strips 2.

[0067] This embodiment provides a specific implementation method for adjusting the flatness of the ninth bolt 101 and the tenth bolt 102. The four bolts achieve flatness adjustment of four points on the upper end face of the T-shaped profile.

[0068] In one embodiment, the present invention also provides a straightening method for a steel profile straightening device, the straightening method comprising:

[0069] S101, insert the opposite channel steels 1 into the two sides of the flange 201 of the T-profile 200 through the openings 11 respectively.

[0070] This step provides a specific procedure for adjusting the positional relationship between the channel steel 1 and the T-profile 200. At this time, the lower end face of the flange 201 of the T-profile 200 is attached to the lower bottom surface inside the channel steel 1, which also supports the lower end face for adjusting deformation.

[0071] S102, adjust the height of the channel steel 1 by adjusting the third bolt 5 and the fourth bolt 6.

[0072] This step provides a specific procedure for adjusting the height of the third bolt 5 and the fourth bolt 6. This step mainly involves adjusting the height of the channel steel 1, on the one hand to adapt to the height of the flange 201 of the T-profile 200, and on the other hand to adjust the height of the reference surface of the lower bottom surface.

[0073] S103, adjust the height of the first bolt 3 and the second bolt 4 to level the wing plate 201.

[0074] This step provides a specific procedure for adjusting the height of the first bolt 3 and the second bolt 4. The ends of the first bolt 3 and the second bolt 4 will press against the upper surface of the wing plate 201, thus ultimately achieving the correction of the wing plate 201.

[0075] This embodiment provides a straightening method for a steel profile straightening device. Specifically, it provides a reference plane in space and straightens the steel profile from top to bottom using a first bolt 3 and a second bolt 4. Before that, it uses a third bolt 5 and a fourth bolt 6 to level the channel steel 1 to adapt to the height of the T-profile 200 and to provide a reliable reference plane.

After the step of adjusting the height of the channel steel 1 by adjusting the third bolt 5 and the fourth bolt 6, the method further includes:

[0080] Adjust the seventh bolt 9 and the eighth bolt 10 to level the flatness of the channel steel 1.

[0081] In this embodiment, the flatness of the channel steel 1 can be adjusted by adjusting the seventh bolt 9 and the eighth bolt 10 to form a four-corner structure with the third bolt 5 and the fourth bolt 6.
