Problems solved by technology

However, there are multiple gaps between the magnetizing chucks of the magnetizing fixture. If there is a filler in the gap, after a long time of use, the filler in the gap is prone to cracks due to the expansion and contraction of the coil, which will affect the service life of the magnetizing fixture.

Abstract

The invention discloses a multi-pole magnetization device for a magnetic ring. The multi-pole magnetization device comprises an annular ring and magnetizing poles; two pairs of more than two and an even number of pairs of magnetizing poles are evenly arranged inside the annular ring in the radial direction; each magnetizing pole is wound with a coil; a magnetic shielding insert is arranged between every two adjacent magnetizing poles; a fan-shaped gap between every two adjacent magnetizing poles is filled with an insulating material. The multi-pole magnetization device has the advantages that the gaps between the magnetizing poles are eliminated by use of the inserts, and the insulating material in the gaps can be prevented from cracking after long-time use.

Description

technical field [0001] The invention relates to the technical field of magnetic ring magnetization, in particular to a multi-pole magnetization device for a magnetic ring. Background technique [0002] With the increasing application of magnetic materials, customers require more and more types and quantities of products supplied by magnetization, and the requirements for magnetization are getting higher and higher, so the requirements for the production of magnetic fixtures are getting higher and higher. There is a certain gap between the poles of a general multi-pole magnetizing device. When the magnetizing device is in use, the coils wound between adjacent poles are likely to touch and interfere, causing accidents. After the insulation filler is added to separate the magnetized coils on each pole head after a long period of charge and discharge, the coils will continue to expand and shrink, and the solidified filler will easily produce cracks in the gap between the pole he...
