Method for manufacturing magnetic tiles with magnetic field lines diffusing in radiating mode

Abstract

The invention relates to a method for manufacturing magnetic tiles, in particular to a method and a device for manufacturing the magnetic tiles with magnetic field lines diffusing in a radiating mode. By means of the method and the device, the problem that permanent-magnet tiles with the magnetic field lines beta perpendicular to a tangent plane direction of arc surfaces in a point-to-point mode cannot be manufactured previously can be solved. The method for manufacturing the magnetic tiles with the magnetic field lines diffusing in the radiating mode comprises the following steps: (1) cleaning the surface of a magnetic block M with the magnetic field lines beta parallelly distributed; and (2) manufacturing a base through materials which cannot start physicochemical reactions with the magnetic block M, wherein an arc surface is arranged at the top of the base, an arc-shaped cavity with the same radian with the arc surface is arranged under the arc surface on the base, and through holes which are communicated with the arc-shaped cavity and distributed full of the arc surface are arranged on the arc surface. By means of the method and the device, reasonable design and easy and convenient operation can be achieved, and thermal deformation treatment with guiding performance is conducted on a rear earth-iron-boron series permanent magnet body which is formed by processing by adopting a thermal treatment method, and the magnetic tiles with the magnetic field lines beta focused to be distributed in the radiating mode can be manufactured finally.

[0003] The existing method of preparing magnetic tiles is as follows: Through mature sintering rare earth-iron-boron permanent magnet system preparation methods, first prepare magnetic block m (such as such as magnetic line β parallel distribution (such as such as Figure 7 Show), and then prepare a tile shape through the mechanical processing process of line cutting. The magnetic tile β of the magnetic tile produced by this method is still parallel distribution, and the magnetic line β point is perpendicular to...
