s3, after the edge rolling forming, the surface temperature of the formed part can rise, and for avoiding the formed part from generating secondary deformation, a small water pump (132) is started, so that water in a cooling water tank (131) is extracted through a water pumping pipe (135), then the water is conveyed to a cooling spray nozzle (134) through a bent pipe (133) and sprayed to the formed part, the formed part is rapidly cooled, and the formed part is prevented from generating secondary deformation.
