The invention discloses a device and method for forming a three-dimensional curved surface of a plate, and belongs to the technical field of plate stamping, the device comprises a die frame, a supporting unit, a basic body unit, a lifting platform, a limiting ring and an upper die assembly, the supporting unit provides supporting force for the lifting platform, the basic body unit comprises a basic body and a pressing head, and a plate is placed on the top of the pressing head. The lifting platform abuts against the supporting unit and the basic body units and can move up and down, so that the basic body units are located on the same plane before a plate is deformed, and the basic body units make contact with the plate all the time in the forming process. Each basic body is sleeved with a limiting ring, the height of each limiting ring is designed according to the shape of a curved surface to be formed, the stroke of each basic body is accurately controlled by adjusting the height of each limiting ring, and t
