Abstract
The invention discloses a high-magnetic-performance neodymium-iron-boron magnet capable of recycling waste materials and a preparation method thereof, and relates to the technical field of magnet production, the high-magnetic-performance neodymium-iron-boron magnet comprises a neodymium-iron-boron magnet main body, mounting holes are uniformly formed in the top and the bottom of the neodymium-iron-boron magnet main body, and inserting rods are embedded in the mounting holes; limiting rings are installed on the top of the upper inserting rod and the bottom of the lower inserting rod, four baffles arranged at equal intervals are installed on the surfaces, close to each other, of the two limiting rings, first storage grooves are formed in the bottoms of the upper baffles and the tops of the lower baffles, and magnetic guiding pieces are installed in the first storage grooves in an embedded mode; and an iron sheet is embedded in the first storage groove on the lower side. According to the neodymium-iron-boron magnet, the mounting holes, the inserting rods and the limiting rings are arranged, firstly, the neodymium-iron-boron magnet body is fixed between the two sets of limiting rings through embedding of the inserting rods and the mounting holes, and the stability of connection between the two sets of limiting rings is improved through attraction of the magnetic guiding sheets and the iron sheets.
