Problems solved by technology

NdFeB magnets are called "magnet kings". They have the highest remanence and magnetic energy product among all kinds of permanent magnet materials, and also have high coercive force. With the improvement of the performance of commercial NdFeB magnets, NdFeB magnets Boron devices are developing towards small size, ultra-thin, and special-shaped. The existing NdFeB cannot solve the problem of poor reliability of the surface coating of the product caused by glue coating, curing, and water glue non-conductivity in the production process. Therefore, a neodymium Iron boron process processing procedure

Embodiment example

[0022] A kind of neodymium iron boron process processing procedure, specifically comprises the following steps:

[0023] S1. Material selection: NdFeB is selected as the raw material according to the requirements of the customer's drawings.

[0024] S2. Initial slicing: the NdFeB prepared in S1 is preliminarily sliced ​​by a slicer to form two NdFeB sheets.

[0025] S3. Surface treatment: the NdFeB sheet in S2 is polished by a grinding device. After completion, the polished NdFeB sheet is placed in the bellows, and the impurities on the NdFeB sheet are cleaned through the bellows;

[0026] S4. Glue application: take out the two treated NdFeB sheets, apply glue evenly on the front of one of the NdFeB sheets, and evenly apply glue on the reverse side of the other NdFeB sheet, and set aside after completion;

[0027] S5. Press forming: place the two NdFeB sheets in S4 on the extrusion device, and press the front and back sides of the two NdFeB sheets.

[0028] S6. Glue curing: ...

Abstract

The invention discloses a neodymium-iron-boron processing working procedure. The neodymium-iron-boron processing working procedure comprises the following steps: S1, material selection; S2, first slicing; S3, surface treatment; S4, gumming; S5, compression molding; S6, glue solidification; S7, slicing again; S8, surface treatment again; S9, magnetizing; and S10, packaging. According to the neodymium-iron-boron processing technology of magnetic poles in different directions disclosed by the invention, an original neodymium-iron-boron processing technology is broken through, magnets are not adhered commonly, but two neodymium-iron-boron slices are specially adhered to realize the magnetic poles in different directions on one side, and the problem of poor product surface coating reliability caused by the fact that gumming, solidification or glue is free of electric conduction in the manufacturing process is solved, so that the performance and using method are further improved, and wider applications are obtained in modern industry and electronic technique.

Description

technical field [0001] The invention relates to the technical field of magnet preparation, in particular to a neodymium-iron-boron process. Background technique [0002] As the third generation of rare earth permanent magnet materials, NdFeB rare earth permanent magnet materials have been commercialized and developed by Japan's Sumitomo Metal and American GM Corporation in 1983. Due to the characteristics of high remanence, high coercive force and high magnetic energy product , are widely used in power electronics, communications, information, motors, transportation, office automation, medical equipment, military and other fields, and make the application of some small, highly integrated high-tech products possible. To meet the above market needs, we need NdFeB magnets with both high remanence and high coercivity are prepared at a lower cost. NdFeB magnets are called "magnet kings". They have the highest remanence and magnetic energy product among all kinds of permanent mag...
