Abstract
The invention relates to a radial magnetization plastic magnet. The radial magnetization plastic magnet is an annular magnet, the wall thickness of the magnet changes according to rules of sine waves, and the position of the wave crest of the wall thickness corresponds to the position of the wave crest of magnetic performance. According to the radial magnetization plastic magnet, the wall thickness of the magnet changes according to the rules of the sine waves and the position of the wave crest of the wall thickness corresponds to the position of the wave crest of the magnetic performance, so needed materials are greatly reduced, the product cost is saved, the product quality is improved, the logistics cost is lowered, and the product competitiveness is improved.
Description
Technical field
The present invention relates to a kind of radial magnetizing and mould magnet.
Background technology
Radial magnetizing is moulded magnet two kinds of forms conventionally: inside fill multi-pole magnet and fill multi-pole magnet outward, because the magnetic property of radial magnetizing is to change with the variation of wall thickness, and the magnetic property of radial magnetizing is sinusoidal wave, if the wall thickness of magnet is constant, certainly will cause the waste of material, thereby the cost of product is significantly improved, and the increase of product weight also can increase logistics cost.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of radial magnetizing of waste of material that can not cause to mould magnet.
For addressing the above problem, the technical solution used in the present invention is: a kind of radial magnetizing is moulded magnet, is an annular magnet, and the wall thickness of its magnet is with sinusoidal wave rule size variation, and the position of wall thickness crest is the crest location to magnetic property just.
On the outer wall of described magnet, be evenly arranged at intervals with outer groove along hoop.
On the inwall of described magnet, be evenly arranged at intervals with inner groovy along hoop.
The invention has the beneficial effects as follows: above-mentioned radial magnetizing is moulded magnet, its wall thickness by magnet is designed to sinusoidal wave rule size variation, the position of wall thickness crest is the crest location to magnetic property just, thereby reduce greatly material requested, save the cost of product, the quality that has reduced product, has reduced logistics cost, has improved the competitiveness of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the present invention;
Fig. 2 is the structural representation of another kind of embodiment of the present invention;
In figure: 1, magnet, 2, outer groove, 3, inner groovy.
Embodiment
Below by specific embodiment, a kind of radial magnetizing of the present invention being moulded to magnet is described in further detail.
As shown in Figure 1, a kind of radial magnetizing is moulded magnet, for interior form of filling multi-pole magnet, it is an annular magnet 1, on the outer wall of described magnet 1, be evenly arranged at intervals with outer groove 2 along hoop, the wall thickness of its magnet 1 is with sinusoidal wave rule size variation, and the position of wall thickness crest is the crest location to magnetic property just.
As shown in Figure 2, a kind of radial magnetizing is moulded magnet, for filling the form of multi-pole magnet outward, it is an annular magnet 1, on the inwall of described magnet 1, be evenly arranged at intervals with inner groovy 3 along hoop, the wall thickness of its magnet 1 is with sinusoidal wave rule size variation, and the position of wall thickness crest is the crest location to magnetic property just.
Above-mentioned radial magnetizing is moulded magnet, its wall thickness by magnet is designed to sinusoidal wave rule size variation, the position of wall thickness crest is the crest location to magnetic property just, thereby reduce greatly material requested, save the cost of product, the quality that has reduced product, has reduced logistics cost, has improved the competitiveness of product.
The above embodiments are principle and effect thereof of illustrative the invention only, and the embodiment of part utilization, but not for limiting the present invention; It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
