[0037] The rear end surface of the bracket 100 is provided with a horizontal holding device 400, and the horizontal holding device 400 includes a slide groove 401, the surface of the slide groove 401 is opened on the rear side surface of the bracket 100, the interior of the slide groove 401 is slidably connected with a slider 404, the inner wall of the slider 404 is slidably connected with a slide rod 402, the surface of the slide rod 402 is sleeved with a pressure spring 403, the top of the pressure spring 403 is fixedly connected to the bottom surface of the slider 404, the bottom of the pressure spring 403 is fixedly connected to the inner bottom of the slide groove 401, the pressure spring 403 is sleeved on the surface of the slide rod 402, and is fixedly connected to the slider 404 and the slide groove 401. The bottom can provide shock absorption and buffering effects, spring rebound force, stability and precision, and reduce friction, thereby improving the operating efficiency and stability of the entire device. The two ends of the slide rod 402 are fixedly connected to the inner wall of the slide groove 401. The rear end top surface of the bracket 100 is equipped with an electric telescopic rod 405. The output end of the electric telescopic rod 405 passes through the top surface of the slide groove 401 and is fixedly connected to the top surface of the slider 404. By passing the output end of the electric telescopic rod 405 through the top surface of the slide groove 401 and fixedly connected to the top surface of the slider 404, it can be ensured that the output end of the electric telescopic rod 405 and the slider 404 are in contact with each other. The positional relationship remains stable, thereby achieving precise control of the movement of the slider 404. The central surface of the bracket 100 is equipped with a motor 406 and a roller rod 300. The two ends of the motor 406 and the roller rod 300 are fixedly connected to the inner walls on both sides of the bracket 100. The bottom of the motor 406 is fixedly connected to a hollow block 409. The inner wall of the hollow block 409 is slidably connected to a positioning block 412. The bottom of the positioning block 412 is fixedly connected to the top of the induction telescopic rod 407. The surface of the hollow block 409 is penetrated and plugged with a bolt assembly 411, which is connected to other components through the bolt assembly 411 to ensure the stability of the system, control the movement, and provide a firm connection. The bottom of the positioning block 412 is fixedly connected to the top of the induction telescopic rod 407, ensuring that the position of the hollow block 409 is fixed and will not shift or swing due to movement. The top surface of the induction telescopic rod 407 is fixedly connected with a soft wire 410, and the top of the soft wire 410 is fixedly connected to the bottom surface of the motor 406. Through the soft wire 410, the motor 406 can receive power supply and signal transmission, and control the operation of the electric telescopic rod 405 through the soft wire 410, and provide the function of flexible connection and protection of the wires. The bottom inner wall of the hollow block 409 is equipped with the induction telescopic rod 407, and the output end of the induction telescopic rod 407 is rotatably connected with a rotating wheel 408.

[0038] When in use, the cold rolling component 200 first rolls the steel, and then one end of the steel is placed on the surface of the roller rod 300, and then the roller rod 300 is started to rotate, so that the pressed steel plate is wound on the roller rod 300. As the volume of the steel plate gradually increases when the roller rod 300 is wound, an angle error is formed between the curvature of the steel plate wound on the top of the roller rod 300 and the curvature of the center of the cold rolling component 200. As a result, after the cold rolling of the steel plate, the surface of the steel plate is easily deformed when the steel plate is wound on the roller rod 300, and the induction telescopic rod 407 at the top of the rear end of the bracket 100 is used, and then the rotating wheel 408 at the output end of the induction telescopic rod 407 is attached to the top of the steel plate. When the steel plate is wound When the angle of the plate is tilted upward, the outer surface of the wrapped steel plate squeezes the top inductive telescopic rod 407, and the signal of the squeezing of the inductive telescopic rod 407 is transmitted to the motor 406 through the electrical connection of the soft wire 410, so that the motor 406 drives the electric telescopic rod 405 to extend downward, and at the same time, the electric telescopic rod 405 pushes the slider 404 at the output end to slide along the slide groove 401 on the inner wall of the bracket 100, driving the roller rod 300 assembled on the surface of the slider 404 to move downward synchronously to control the horizontal angle of the roller rod 300 and the surface of the cold rolling component 200, and the bolt assembly 411 inside the hollow block 409 can adjust the distance between the inductive telescopic rod 407 and the steel plate to adapt the equipment to processing steel plates of different thicknesses.

[0039] At the same time, in order to limit the position of steel with different widths, please refer to Figure 1-Figure 7 As shown in the figure, a limiting device 500 is arranged at the top center of the bracket 100, and the limiting device 500 includes a second slide groove 501. The surface of the second slide groove 501 is opened on the top surface of the bracket 100. The inner wall of the second slide groove 501 is slidably connected with an L-shaped support block 502. The surface of the L-shaped support block 502 close to the center of the bracket 100 is fixedly connected with a support block 503. The surfaces of the L-shaped support block 502 and the support block 503 are both rotatably connected with a roller 504. By utilizing the contact between the roller 504 and the steel plate, the friction can be effectively reduced, the surface of the steel plate is protected, and the To provide a smoother flow of steel plates, thereby improving the quality and efficiency of the processing process, the top of the L-shaped support block 502 is slidably connected to a round rod 506, the top of the round rod 506 is fixedly connected to a pull ring 507, the bottom of the round rod 506 is fixedly connected to a pressure plate 505, the top of the pressure plate 505 is fixedly connected to an air bag 508, the top of the air bag 508 fits the surface of the L-shaped support block 502, and the contact between the pressure plate 505 and the L-shaped support block 502 is closer, thereby ensuring that the steel plate will not move or shake during the processing, providing additional fixation and stability.

[0040] During use, when the cold rolling assembly 200 processes a steel plate and puts it onto the roller rod 300, the L-shaped support block 502 at the top center of the bracket 100 is used to position the width of the steel plate to prevent the steel plate from being misplaced during processing. The L-shaped support block 502 uses the roller 504 on the surface to fit the steel plate, reducing the friction between the L-shaped support block 502 and the steel plate, allowing the steel plate to flow more smoothly. At the same time, before putting in the steel plate, the staff first pulls up the pull ring 507 to drive the round rod 506 to slide on the top of the L-shaped support block 502. When the steel plate is placed on the L-shaped support block 502, the pressure plate 505 at the bottom of the round rod 506 is used to hold the steel plate to prevent the steel plate from popping out during flow and causing damage to the surface of the equipment.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
