| 简介 |
The present invention refers to a rare earth element based produced in the magnet N, uniformly vertical boundary pole S the rare earth magnet for manufacturing device relates to press magnetic field and magnetic field press method, a rare earth alloy after solidification and the object to a substituting then, substituting said comprised applies the air orifice, the constant pressure the magnet characteristics and to easily mold a compact of magnetic field which press step, the arrangement of magnet and the magnet molded body to sinter, a method has the steps of method for producing a rare earth element based magnet in; said magnetic field press step, on, said substituting layer filled is open under the internal filling space outside the magnetic field forming part die prepared with internal mold the mold frame and a non-compression substituting and the charge material in an area of magnetic, and preparing a mold the, on said, the mold provided substituting between said magnetic field forming unit applies the magnetic field to substituting on, the substituting produced by cutting a by pressing the magnet forming for forming a rare earth element based, can form a magnetic field for fabricating LED having large surface area due. characterized by a press method.
Furthermore, rare earth alloy magnet be a raw material of constant substituting the magnet applied magnetic field while being applied with a pressure, pressure characteristics and to easily mold a compact of magnetic field which press device in fabricating LED having large surface area due rare earth including a device, a device press said magnetic field, on, said substituting is open under the internal layer filled due to an outside space filling S pole direction N pole a magnetic field is the magnetic field forming part die prepared with frame, said charge material in an area except the space filling internal mold mold applies the compression substituting substituting comprised of a non-magnetic, the molds, and rare earth magnet for manufacturing press device. characterized by a magnetic field. |
