摘要： A device for producing a pattern onto a work piece is disclosed. 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.

摘要： A device producing a patterned plate includes a die and an electromagnetic actuator. The die includes a patterned surface with a pattern formed thereon and a fracturing part. The tubular work piece is disposed between the die and the electromagnetic actuator such that walls of the tubular work piece correspond to walls of the die. When the electromagnetic actuator is supplied with a current pulse, an eddy current is induced in the tubular work piece, generating a repulsive force between the electromagnetic actuator and the tubular work piece. Therefore, the tubular work piece impacts the die, and a forming surface of the tubular work piece is deformed against the patterned surface and the fracturing part, thus replicating the pattern of the patterned surface onto the forming surface. At the same time, the tubular work piece is fractured at the position corresponding to the fracturing part.

摘要： An electromagnetic forming device for a sheet of material is provided. The electromagnetic forming device includes a fixing base, a magnetic concentration block, an electromagnetic actuator, and a die. The fixing base has a groove. The magnetic concentration block is disposed in the groove of the fixing base, and has an accommodating space therein, which is in communication with a surface of the magnetic concentration block via a slit. The electromagnetic actuator, used to generate a magnetic field, is disposed in the accommodating space of the magnetic concentration block, but does not contact the magnetic concentration block. The die and the magnetic concentration block are separated by a gap, and a sheet of material can be disposed in the gap. As the magnetic concentration block is a block, eddy currents in the magnetic concentration block are distributed uniformly, so the generated magnetic field is also distributed uniformly, thus exerting a uniform forming force on the sheet of material.
