Abstract
The utility model discloses a sintered NdFeB multi-pole magnet ring, which is characterized in that the magnet ring comprises a columnar circular ring body, a plurality of tile-shaped sheet bodies and an anti-explosion ring-shaped body, wherein the tile-shaped sheet bodies are stuck onto the outer wall at the periphery of the columnar circular ring body, and the anti-explosion ring-shaped body is positioned at the end part of the columnar circular ring body; the tile-shaped sheet bodies are stuck onto the outer wall at the periphery of the columnar circular ring body through glue; the tile-shaped sheet bodies are made of sintered NdFeB, and the columnar circular ring body and the anti-explosion ring-shaped body are manufactured by magnetic conducting pure iron. The magnet ring has the advantages of excellent and stable performance and good consistency; the outside diameter is greater than 5mm, the height is 250mm and the wall thickness is greater than 1.5mm, so as to greatly facilitate the selectivity of the people; without the need of special dies in the production process, only the common machining is needed; and the cost is low, the efficiency is high, and only the ordinary magnetizing equipment is needed for magnetizing.
Description
Technical field
The utility model relates to a kind of sintered NdFeB multi-pole magnet-ring, specifically a kind ofly processes the magnet ring simple, that cost is low, efficient is high.
Background technology
The manufacture process of present radially oriented sintering magnetic Nd-Fe-B ring all has very big restriction to performance and specification, and external diameter requires 15-150MM, height 60MM, wall thickness 2.5-3.5MM, be significantly less than the performance of square shape, instability, the user of use generally believes explosion easily in the use.Also need special mould, mould takes present subsistence level more than 100,000, and magnetizes and also need to the special magnetized head of foreign procurement, the magnetized head that each specification all will be mated, and the threshold of use is than higher.
Summary of the invention
The purpose of this utility model provides a kind of magnet ring simple, that cost is low, efficient is high of processing.
The purpose of this utility model is achieved through the following technical solutions.
A kind of sintered NdFeB multi-pole magnet-ring is characterized in that: described magnet ring comprises column torus, some watts of shape plates and blast ring body, and watt shape plates are bonded on the toric outer circumferential walls of column, and the blast ring body is positioned at the toric end of column.
Described watt of shape plates are bonded on the toric outer circumferential walls of column by glue.
Described watt of shape plates are made by sintered NdFeB, and column torus and blast ring body are made by the permeability magnetic material pure iron.
The utility model compared with prior art has the following advantages.
Magnet ring described in the utility model has the following advantages: the performance height; Stable performance, high conformity; External diameter is from more than the 5MM, height 250MM, and wall thickness improves people's selectivity more than 1.5 greatly; Need special dies in the production process, general machining gets final product, and cost is low, the efficient height, magnetizing only needs common magnetizing equipment just passable.
Description of drawings
Fig. 1 is the front view of the utility model magnet ring;
Fig. 2 is the vertical view of the utility model magnet ring.
Embodiment
Below in conjunction with accompanying drawing the utility model magnet ring is described in further detail.
As Fig. 1 and shown in Figure 2, magnet ring described in the utility model comprises column torus 1, some watts of shape plates 2 and blast ring body 3, and watt shape plates are bonded on the toric outer circumferential walls of column, and the blast ring body is positioned at the toric end of column.Watt shape plates are bonded on the toric outer circumferential walls of column by glue.Watt shape plates are made by sintered NdFeB, and column torus and blast ring body are made by the permeability magnetic material pure iron.Magnet ring described in the utility model has the following advantages: the performance height; Stable performance, high conformity; External diameter is from more than the 5MM, and height 250MM, wall thickness be more than 1.5, greatly the guest's of Ti Gaoing selectivity; Need special dies in the production process, generally all machining gets final product, and cost is low, the efficient height, magnetizing only needs common magnetizing equipment just passable.
