When the aluminum plate is formed into a curved surface, according to the required curvature, the first forming roller is pressed down by different distances, and when the aluminum plate passes through the first forming channel and the second forming channel in sequence, the aluminum plate is formed into a curved aluminum plate with a required curvature under the extrusion of the three forming rollers, and the opening of the curved aluminum plate faces upward.

[0004] However, the three-roller bending machine in the related art needs a production personnel to take out the formed aluminum plate, so that the production efficiency of the aluminum plate is limited by the speed of the production personnel in taking the aluminum plate. SUMMARY
