Abstract
The invention relates to a radial magnetizing or orientating device comprising a spiral tubular magnetizing and orientating magnetic field coil, an upper die, a lower die and magnet-conducting plates. The upper die and the lower die are made from a non-magnet-conducting material, and the magnet-conducting plates are made from a material with high magnetic conductivity. When the radial magnetizing or orientating device is in work, original parallel magnetic force lines of a magnetic field are adjusted to approximate radial magnetic force lines so as to radially magnetize and orientate a tile-shaped permanent magnet working piece. By changing an included angle between the magnet-conducting plates, the invention can conveniently adjust the radiation state of the magnetic field and further change the magnetic force line direction and the magnetic flux density ratio of the magnetizing or orientating magnetic field on the inner surface and the outer surface of the tile-shaped permanent magnet material so as to change the surface magnetic state, the magnetic density waveforms, and the like of the inner surface and the outer surface of the permanent magnet working piece and satisfy the working requirements of different products.
Description
Technical field
The present invention relates to a kind of permanent magnet radiation and magnetize or aligning device, relate in particular to and a kind of watt shape permanent magnet radially carried out the device that radiation is magnetized or is orientated.
Background technology
Watt shape magnetic material is widely used in field of magnetic material, the magnetic line of force direction that product greatly wherein arranged for watt shape cambered surface radially, working face also is single working face.If can control and improve table magnetic, the magnetic flux density waveforms of magnet working face on request, just can directly improve the work effect of permanent magnet.
Number of patent application is: 200720191419.5 Chinese utility model patent, a kind of radial radiation magnetizer is disclosed, and claim to solve the demanding problem of table magnetic, magnetic flux and magnetic flux density waveforms that prior art exists to the magnet working face.After the anchor clamps that this device is made for use upper and lower two secondary pure iron are changed into radiation direction with the magnetic line of force direction in the original parallel magnetic field of magnetizing, to radially the magnetizing of watt shape permanent magnet workpiece of magnetizing for the treatment of between the upper and lower anchor clamps, to reach table magnetic, magnetic flux that improves the magnet working face or the purpose of improving magnetic flux density waveforms.Though but think that after we research and analyse this device has certain effect, but because structural defective, the radiation center point in magnetic field of magnetizing is difficult to watt shape wait to magnetize inside and outside arc central point of workpiece concentric, radiation effect is also limited, and the position of the radiation center point in magnetic field can not be controlled, thereby being difficult to has control to regulate by need of work to the relation of inside and outside magnetic flux density of watt shape workpiece, to reach the purpose of different demands.
Summary of the invention
Purpose of the present invention is exactly in order to address the above problem, and a kind of device that watt shape permanent magnetic material is carried out radial magnetizing or orientation that provides.There is work structuring simple, the easily characteristics that realize, and magnetic field radiation central point
Adjustable, reach and can need improve the table magnetic of magnet working face or improve the purpose of magnetic flux density waveforms by workpiece.
The object of the present invention is achieved like this: a kind of radiation is magnetized or aligning device, comprises that helix magnetizes or the alignment magnetic field coil.Coil central authorities are provided with the upper and lower mould that non-magnet material is made, and the lower end of mold has one section to be arc, so as with wait to magnetize or be orientated the interior side-to-side anastomosis of workpiece.There is one section approximate arc the upper end of bed die, so as with wait to magnetize or be orientated the outer side-to-side anastomosis of workpiece.Upper and lower mould be combined to form one watt of shape space, in order to fixing or fill a watt shape and wait to magnetize or be orientated the permanent magnetism workpiece.The both sides of upper and lower mould are respectively equipped with symmetrical distribution, and are the plate shaped magnetic conductive board of being made by high-permeability material of an angle mutually.
Operation principle is: by magnetizing or the work of oriented coils, can produce the magnetic field that the magnetic line of force is almost parallel at the coil central part, this magnetic line of force is through magnetic conductive board the time, because the effect of the high-permeability material of magnetic conductive board, the magnetic line of force can change direction along the trend of magnetic conductive board, is approximate radial trend between two magnetic conductive boards.
Because upper and lower mould is non-magnet material and makes, so magnetize or alignment magnetic field when the upper and lower mould, upper and lower mould can not change the radiation direction in magnetic field, to guarantee that the magnetic line of force is through waiting to magnetize or the correctness of magnetic field trend when being orientated workpiece body surperficial.
The radiation center of the radiative collision line of force is similar to the joint at the plane of both sides magnetic conductive board extended line.From geometry principle, we can learn: if the radiation center position is concentric with watt center of circle of the arcwall face of shape workpiece, then magnetizing or be orientated the magnetic line of force will be perpendicular to the inside and outside surface of watt shape workpiece; As both decentraction, then magnetic line of force meeting slightly inclined is in watt inside and outside surface of shape workpiece.Magnetize simultaneously or alignment magnetic field also can change because of the difference of radiation center position to some extent in watt magnetic flux density of the inside and outside surface action of shape workpiece.So we can adjust the radiation center position of the radiative collision line of force by the angle that changes the both sides magnetic conductive board, and then can be as required to magnetizing or alignment magnetic field carries out regulating and controlling in the proportionate relationship of watt incident direction on the inside and outside surface of shape permanent magnet workpiece and magnetic flux density, to reach the purpose of different demands.
