[0016] In order to make the content of the present invention more clearly understood, the present invention is further described in detail below according to specific implementation modes and in combination with the accompanying drawings.

[0017] Figure 1 The schematic diagram of the structure of the thin steel plate head and tail S-bend correction device provided in the embodiment of the present application includes a base 1, a support platform 2 and a pressing component. The steel plate to be corrected is placed on the support platform 2, and the pressing component can press down and correct the bent part of the steel plate.

[0018] For details, see Figure 1, the support platform 2 is arranged on the base 1. There are two support platforms 2, which are arranged in sequence along the length direction of the base 1, and a certain gap is left between the two support platforms 2. When the steel plate to be corrected is placed on the two support platforms 2, the bent portion of the steel plate to be corrected is located in the gap between the two support platforms 2.

[0019] Preferably, the two support platforms 2 are both slidably set on the base 1 and can slide back and forth along the length direction of the base 1. The distance between the two support platforms 2 can be adjusted according to the curvature of the steel plate head and tail and the yield strength of the steel plate, so as to achieve a suitable deformation distance and ensure the correction effect.

[0020] In this embodiment, a bidirectional screw assembly is provided on the base 1, and the bidirectional screw assembly includes a bidirectional screw rotatably provided on the base 1, and two threaded sections on the bidirectional screw are threadedly matched with a moving seat, and two support platforms 2 are respectively fixedly mounted on the two moving seats. The bidirectional screw assembly also includes a drive motor for driving the bidirectional screw to rotate around its own axis, and the drive motor is fixedly mounted on the base 1. When the drive motor is running, it will drive the bidirectional screw to rotate around its own axis, and through the threaded match between the bidirectional screw and the moving seat, the two moving seats can be synchronously moved toward or away from each other, thereby realizing the adjustment of the distance between the two support platforms 2.

[0021] The pressing assembly includes a lifting drive device 4 fixedly mounted on the base 1 and a pressing plate 3 connected to the lifting drive device 4. When the lifting drive device 4 is in operation, it drives the pressing plate 3 to rise and fall in the vertical direction. Figure 1 The pressing plate 3 is located between the two supporting platforms 2, and the spacing between the pressing plate 3 and the two supporting platforms 2 is equal. This ensures that the pressing plate 3 is aligned with the curved portion of the steel plate to be corrected, thereby ensuring the correction effect.

[0022] Better, see Figure 1 A hard ball head 5 is fixedly mounted at the lower end of the pressing plate 3. When the pressing plate 3 corrects the bent portion of the steel plate, the hard ball head 5 contacts the surface of the steel plate, which can effectively avoid scratches and pits on the surface of the steel plate caused by friction between the pressing plate 3 and the steel plate, thereby ensuring the surface quality of the steel plate.

[0023] It should be noted that the diameter of the hard ball head 5 is greater than the width of the pressing plate 3 .

[0024] Therefore, the technical solution of the present application can quickly adjust the deformation stroke and correction position to ensure the correction effect on the bent part of the steel plate. At the same time, it can avoid scratches and pits on the surface of the steel plate, effectively correct the blind area of ​​the head and tail straightening of the steel plate, and is convenient, safe and reliable to use, meeting the correction requirements of the head and tail S-bend of the steel plate.

[0025] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
