发明名称 MANUFACTURE OF RARE EARTH MAGNET
摘要 PURPOSE:To industrially manufacture a sintered material integral with a metal material in which an adhering step is omitted by pressure molding crude magnetic alloy powder in a magnetic field, sintering it by discharging, and simultaneously baking to integrate the molding with a metal material, such as a yoke material or the like. CONSTITUTION:A metal material, such as a yoke material 6 or the like is charged in a die 1 formed of a cemented carbide or the like, magnetized in a magnetic field generated by a magnetic field generating coil 4 while compressing it by a hydraulic press 8 by upper and lower punches 2, 3 or only an upper punch 2 for charging a predetermined amount of magnetic powder thereon, and sintered and molded by discharging by simultaneously applying a DC current from a power supply 7. A rare earth sintered magnet sintered integrally with the material 6 is obtained by this operation. Thus, it can be utilized immediately as a component without requirement of steps of working and adhering to be industrially manufactured.
