Description

Technical Field

[0001] The invention belongs to the field of technical magnetizing fixtures, and in particular relates to a planar multi-pole magnetizing fixture of a ejection-type large-size magnetic ring and a realization method thereof. Background Art

[0002] With the increasing application of magnetic materials, the market requires the supply of multi-pole permanent ferrite rings after magnetization, among which there are many permanent ferrite rings with large outer diameter and high thickness. When magnetizing such permanent ferrite rings with large outer diameter and high thickness, the following problems exist:

[0003] After saturation magnetization of a permanent ferrite ring with a large outer diameter and high thickness, because the plane size of this type of ferrite ring is large and the number of plane magnetized poles is large, there is a strong attraction between the ferrite ring and the magnetizing fixture due to the magnetic field after saturation magnetization, and it is very difficult to directly remove the ring from the surface of the magnetizing fixture.

[0004] In the prior art, for example, in a planar multi-pole magnetization device of a large outer diameter and high thickness magnetic ring disclosed in Chinese Patent Application No. 201420759713.1, the contact area between the pressure plate and the magnetic ring and between the magnetic ring and the pole head is gradually reduced by translating the magnetic ring so that the magnetic ring can be removed. However, the translation will generate friction, resulting in surface damage to the magnetic ring. Moreover, due to the large magnetic attraction, even the translation method is still difficult, resulting in high labor intensity and low work efficiency. Summary of the invention

[0010] In order to dissipate heat quickly and increase the service life, a water cooling cavity is further provided inside the base, and symmetrical water inlets and outlets are also provided on the circumference of the base.

A push block is slidably disposed inside the second jacking hole, and the lower end of the push block is connected to the output end of the second electric push rod. Both the push rod and the push block are made of pure iron.
