A device for producing a pattern onto a work piece includes a die, an electromagnetic actuator and a base. The die includes a patterned surface, and the patterned surface includes a pattern. The electromagnetic actuator includes 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 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.

Device for producing patterns

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.
