[0002] Three-dimensional curved corrugated steel plates are widely used in industry due to their advantages such as high strength and good stability. When manufacturing three-dimensional curved corrugated steel plates, the steel plates are generally pressed into a curved shape to form curved steel plates. Then, a wave punching machine is used to press multiple corrugations on the curved steel plates according to a certain wave pitch and depth. By controlling parameters such as the wave pitch and corrugation depth, the steel plates can be formed with different curvatures. However, the current wave punching process does not have accurate control over the wave pitch. The width of the steel plates often increases during the process of pressing the corrugations, and the steel plates can also be distorted. Existing equipment cannot correct the shape of the three-dimensional curved corrugated steel plates after wave punching, resulting in a large deviation between the size of the produced three-dimensional curved corrugated steel plates and the design size.

The bottom die is mounted on the base, and the cutting die is positioned above the bottom die. The cutting die is driven up and down by the hydraulic device. The corrector comprises a correction platform 11, a limiting groove 12, and a cylinder 13. The output end of the cylinder is connected to the limiting groove. The limiting groove is strip-shaped. The correction platform is provided with a working area for the three-dimensional curved corrugated steel plates to pass through. The limiting grooves are located on both sides of the working area, with the openings of the limiting grooves facing the working area. The cylinder drives the limiting grooves toward or away from the working area. The corrugated steel plate processing machine also comprises a frame 21. The cutting die and the bottom die are both located within the frame.

[0025] The wave machine also includes a top plate. The hydraulic system includes an oil pump and a cylinder, which are connected to the cylinder via a pipeline. The top plate is located above the cutting die. A support column is fixedly connected between the top plate and the base. The cutting die is slidably connected to the support column. The cylinder is installed between the top plate and the cutting die. During operation, the curved steel plate is located above the bottom die, and the cylinder drives the cutting die downward, thereby punching out the ripples of a certain depth on the curved steel plate.

[0026] The material of the knife die is steel that has been vacuum heat treated.

[0027] The correction platform is equipped with a roller 14, the axis of which is parallel to the axis of the cylinder's output shaft, and the three-dimensional curved corrugated steel plate moves on the correction platform via the roller. The corrector also includes an air pump 15, which is connected to the cylinder via an air pipe.

[0028] An annular groove is provided on the outer side of the roller.

During use, the left and right surfaces of the cutter die are respectively supported by the left and right stabilizers, preventing the cutter die from shaking during wave operation.

[0035] The wave machine also includes a clamping mechanism, which is installed on both sides of the base. When the steel plate moves into the wave machine and is ready for wave punching, the clamping mechanism clamps both sides of the steel plate and then performs wave punching.

[0038] Feeding: The curved steel plate is fed into the wave punching machine according to a certain step distance through a CNC feeder. The wave distance between two adjacent corrugations can be adjusted by controlling the step distance.

[0039] Wave punching: The curved steel plate fed into the wave punching machine is wave punched at a certain depth to form corrugations. During this process, the depth of the corrugations is controlled by controlling the stroke of the oil cylinder.
