Problems solved by technology

However, in this method, during the feeding process of compression molding, due to the attraction of the magnetic material particles by the magnetic field of the permanent magnet material, the material is blocked at the mouth of the mold cavity, so that the material cannot enter the mold cavity, so automatic feeding and compression molding cannot be realized. , this kind of mold can only be made into a manual mold in which the mold cavity block and the mold cavity wall can be separated. The specific operation process is: first manually weigh a certain amount of material, add it to the mold cavity, and then insert it into the mold The cavity block is pressed after adding the upper and lower die heads. After the pressing, the mold cavity and the mold cavity wall are separated, and the blank is taken out to prepare for the next pressing
Therefore, the pressing efficiency of this method is low, and because the magnetic poles of permanent magnet materials are difficult to provide higher magnetic field strength, it is difficult to further improve the performance of the multi-pole magnetic ring

Abstract

The invention discloses an anisotropic multipole magnet ring forming mold system, and belongs to the field of magnetic material production. The anisotropic multipole magnet ring forming mold system comprises a multipole magnet ring forming mold, and further comprises a plurality of coil windings and an RC charge-discharge circuit, wherein the coil windings are wound on a plurality of magnetic poles in a cavity block of the multipole magnet ring forming mold, and are connected with the RC charge-discharge circuit. According to the anisotropic multipole magnet ring forming mold system, due to the fact that high currents are instantly generated by the RC charge-discharge circuit, the coil windings with the small number of turns can generate magnetic fields which are large enough, magnetic powder particles can carry out directional arrangement through the magnetic fields generated by the coil windings, and conditions are created for implementation of automatic extrusion of anisotropic multipole magnet rings and improvement of magnetic performance of the anisotropic multipole magnet rings.

Description

technical field [0001] The invention relates to a magnetic material production device, in particular to an anisotropic multi-pole magnetic ring forming mold system. Background technique [0002] Multi-pole magnetic rings are widely used in permanent magnet synchronous motors, permanent magnet stepper motors, instruments, timers, sensors, microwave devices, electronic devices and other fields. Compared with isotropic magnetic rings, anisotropic multi-pole magnetic rings It has the advantages of high magnetic performance and high cost performance. Anisotropic magnetic materials need to provide a magnetic field to align and orient the magnetic material particles during compression molding. The higher the degree of orientation of the magnetic material particles, the better the magnetic properties of the magnetic material and the higher the magnetic field strength generated. In order to obtain high magnetic properties, the orientation magnetic field must have sufficient strength...
