Uniform magnetizing device for rare earth permanent magnet material and using method of uniform magnetizing device

Abstract

The invention discloses a uniform magnetizing device for a rare earth permanent magnet material and a using method of the uniform magnetizing device, and relates to the technical field of magnetizing devices. The device comprises a support, two side plates are symmetrically and fixedly connected to the top of the support, semicircular clamping plates are fixedly connected to the lower surfaces of the side plates, arc-shaped supporting strips are fixedly connected to one side faces of the semicircular clamping plates, a charging barrel with openings in the two end faces is rotationally matched between the inner walls of the two arc-shaped supporting strips, and the two ends of the charging barrel make contact with the side faces of the side plates. A shaft rod is rotationally connected between the side faces of the two side plates, and a plurality of stirring rods are fixed to the circumferential side face, located in the charging barrel, of the shaft rod. Through the design of the arc-shaped supporting strip, the charging barrel, the stirring rod, the scraping plate and the gear column, the charging barrel rotates on the arc-shaped supporting strip, so that a rare earth permanent magnet material rolls in the charging barrel, multiple faces of the rare earth permanent magnet material can be magnetized, meanwhile, the stirring rod mixes the rare earth permanent magnet material in the charging barrel, and the rare earth permanent magnet material is evenly magnetized.

Description

technical field [0001] The invention belongs to the technical field of magnetizing devices, in particular to a uniform magnetizing device for rare earth permanent magnet materials and a using method thereof. Background technique [0002] Rare earth permanent magnet material, that is, the permanent magnet material contains rare earth metals as alloy elements. A device for magnetizing permanent magnetic materials. The magnetization of rare earth permanent magnet materials is usually carried out by applying a strong magnetic field, and this magnetization operation generally uses pulse magnets to achieve short-term magnetization by generating a pulse current of hundreds of amperes to generate a strong magnetic field for a short time. With the continuous development of magnetic materials, the requirements for the magnetic field strength during magnetization are getting higher and higher, and it is difficult for pulsed magnets to obtain a strong magnetic field that meets the need...
