Neodymium iron boron magnet sintering method

Abstract

The invention relates to the technical field of neodymium-iron-boron magnet sintering, and discloses a neodymium-iron-boron magnet sintering device which comprises a sliding plate, grinding tool equipment is arranged on the side face of the sliding plate, a driving roller is arranged in the sliding plate, a driving belt is arranged on the surface of the driving roller, a driving rod is arranged onthe surface of the driving belt, a base is arranged on the surface of the sliding plate, a push ring is arranged on the lower surface of the base, a first turning column is arranged on the side surface of the sliding plate, a second turning column is arranged on the side surface of the sliding plate, and a limiting column is arranged on the surface of the base. According to theneodymium-iron-boron magnet sintering device, the driving roller cooperates with the driving belt, the driving rod cooperates with the pull ring, the base cooperates with the sliding plate, and a fixing table cooperateswith thegrinding tool equipment, so that cyclic grinding of the square tneodymium-iron-boron magnet is realized, the edge grinding machining process is simple, the neodymium-iron-boron magnet edge grinding machining effect is good, and the edge grinding machining efficiency is high.

Description

technical field [0001] The invention relates to the technical field of sintering of NdFeB magnets, in particular to a sintering method of NdFeB magnets. Background technique [0002] The sintering of NdFeB magnets is to make the smelted alloy into powder and press it into a compact in a magnetic field. The compact is sintered in an inert gas or vacuum to achieve densification to increase the coercive force of the magnet, usually requiring aging Heat treatment, sintering of NdFeB magnets is a crucial step in the manufacturing process of NdFeB magnets, and it is also a key step in determining the performance and quality of NdFeB magnets. After the sintering of NdFeB magnets, the surface will appear At the same time, after the sintering is completed, the flatness and smoothness of the surface will decrease, so the sintered NdFeB magnets need to be ground and edged. [0003] For the edging processing of square NdFeB magnets, when the existing NdFeB magnets are edging, they need...
