The device comprises a die, an electromagnetic actuator and a base; wherein the die comprises a patterned surface and the patterned surface comprises a pattern. The electromagnetic actuator comprises an plate body, a convex part and a strip unit connected to the plate body; the electromagnetic actuator is disposed in the base. When the electromagnetic actuator is activated while a work piece is being positioned between the patterned surface and the electromagnetic actuator, an inductive current is generated on the work piece by the electromagnetic actuator, and then a repulsive force is generated between the electromagnetic actuator and the work piece. The repulsive force then causes the work piece to adhere to the patterned surface, forcing the work piece to deform against the patterned surface and to take on the shape of the pattern.

Abstract: A device for producing a patterned plate from a tubular work piece is disclosed wherein walls of the tubular work piece comprise at least one forming surface.

Therefore, the tubular work piece impacts the die, and the forming surface is deformed against the patterned surface and the fracturing part, thus replicating the pattern of the patterned surface onto the forming surface.
