Method for producing a rare earth anisotropic bonded magnet, magnetic field forming device orientation and method of processing molded magnet

摘要

This invention, the magnet raw materials after the heating orientation process pressurizing forming, being production method of the rare earth anisotropic bond magnet which consists of the cylindrical magnet compact which at least on the cylindrical side possesses the orientation section of 4 or more where orientation it is done to semi radial distribution, features that it makes the main magnetic direction of the intermediate orientation magnetic field which is impressed between the cavities which it adjoins with that heating orientation process identical. Because of this plural rare earth anisotropic bond magnets can be produced efficiently at one time.
