Abstract

The invention discloses a rotary magnetic field magnetizing apparatus for a neodymium-iron-boron radiation ring magnet, relates to the field of a radiation direction of the neodymium-iron-boron radiation ring magnet, particularly applicable to saturation magnetization of a sintered neodymium-iron-boron large-diameter radiation ring, and particularly relates to a novel radiation magnetic field generation structure with a rotatable magnetic field framework. The rotary magnetic field magnetizing apparatus mainly comprises a rotary magnetic field magnetizing machine main body, a hydraulic oil cylinder, and an electrical system. By adoption of the rotary magnetic field magnetizing apparatus, the problem that the radiation magnetic field magnetization of the sintered neodymium-iron-boron large-diameter radiation ring cannot be realized is solved; the produced sintered neodymium-iron-boron large-diameter radiation ring can be used as a magnetic levitation bearing and a petrochemical engineering pipeline accessory for extending a petroleum hydrocarbon chain to reduce oil transport resistance, so that the application of the sintered neodymium-iron-boron large-diameter radiation ring is expanded and promoted.

Description

Technical field [0001] The invention relates to the field of magnetization in the radiation direction of a neodymium-iron-boron radiation ring magnet, and is particularly suitable for the saturation magnetization of a sintered neodymium-iron-boron large-diameter radiation ring. Background technique [0002] Sintered neodymium iron boron large-diameter radiating ring magnets of 80mm or more can only be magnetized in the radial direction at present, and there is no effective method for magnetizing in the radial direction. Therefore, the development of a device that can magnetize the radiation direction of large-diameter radiation ring products is a key goal of the industry. Summary of the invention [0003] The purpose of the present invention is to provide a magnetizer with a brand-new structure, which is used to produce large-diameter radiating ring magnets that are not currently on the market for magnetizing in the radial direction. [0004] The present invention is realized by ad...
