Abstract
The utility model relates to a permanent magnetic ferrite tile magnetic steel mould for producing auxiliary-direction magnetic field orientation. The permanent magnetic ferrite tile magnetic steel mould is characterized in that non-magnetic steel is embedded in the contact parts of the upper punch and the lower punch of the permanent magnetic ferrite tile magnetic steel mould and magnetic material blank; and the thickness of the non-magnetic steel is set according to the center of the curvature of permanent magnetic ferrite tile magnetic steel. The power output by a micromotor adopting the permanent magnetic ferrite tile magnetic steel produced by the permanent magnetic ferrite tile magnetic steel mould used for producing auxiliary-direction magnetic field orientation is enhanced by 5 percent of the power output by the micromotor adopting the permanent magnetic ferrite tile magnetic steel produced by the permanent magnetic ferrite tile magnetic steel mould for producing parallel magnetic field orientation.
Description
Technical field
The utility model is a kind of permanent-magnet ferrite tile-shaped magnet steel mould for preparing auxilliary to magnetic field orientating.
Background technology
At present, the permanent-magnet ferrite pressing orientating is the parallel magnetic field orientation in the prior art, to the permanent-magnet ferrite of producing bulk or cake shape and structure is rational, this product belongs to low-grade level in affiliated technical field, but the parallel magnetic field orientation is disadvantageous concerning the permanent-magnet ferrite of watt shape structure of top grade, its reason is to have quite a few material not to be orientated fully, so its magnetic property is also effectively utilized.
Summary of the invention
The utility model has overcome the defective of above-mentioned existence, and purpose is the magnetic property that more effectively utilizes permanent magnetic material for solving, and a kind of permanent-magnet ferrite tile-shaped magnet steel mould for preparing auxilliary to magnetic field orientating is provided.
The auxilliary permanent-magnet ferrite tile-shaped magnet steel mould content Description of the utility model preparation to magnetic field orientating:
The auxilliary permanent-magnet ferrite tile-shaped magnet steel mould of the utility model preparation to magnetic field orientating, it is characterized in that: inlay the nonmagnetic steel body at the upper and lower drift of mould and the contact portion of magnetic material blank, the thickness of nonmagnetic steel body is determined by the center of curvature of permanent-magnet ferrite tile-shaped magnet steel.
Prepare the permanent-magnet ferrite tile-shaped magnet steel of assisting to the permanent-magnet ferrite tile-shaped magnet steel die production of magnetic field orientating with the utility model, be used for electrical micro-machine and can make the power output of electrical micro-machine higher more than 5%, effectively utilized the magnetic property of permanent magnetic material than the permanent-magnet ferrite tile-shaped magnet steel of parallel magnetic field orientation production.
Description of drawings
Fig. 1 is the auxilliary permanent-magnet ferrite tile-shaped magnet steel mould structure schematic diagram to magnetic field orientating of preparation
Among the figure: the 1st, mould upper punch, the 2nd, nonmagnetic steel body, the 3rd, nonmagnetic steel body, the 4th, mould low punch.
Embodiment
The auxilliary permanent-magnet ferrite tile-shaped magnet steel mould to magnetic field orientating of the utility model preparation is achieved in that to do below in conjunction with accompanying drawing and specifies.See Fig. 1, the auxilliary permanent-magnet ferrite tile-shaped magnet steel mould of the utility model preparation to magnetic field orientating, upper punch 1 and low punch 4 at mould are inlayed nonmagnetic steel body 2 and nonmagnetic steel body 3 with the contact portion of magnetic material blank, and the thickness of nonmagnetic steel body 2 and nonmagnetic steel body 3 is determined by the center of curvature of permanent-magnet ferrite tile-shaped magnet steel.
The utility model in the production of permanent-magnet ferrite tile-shaped magnet steel is auxilliary to magnetic field orientating with the parallel magnetic field orientation change, thereby has effectively utilized the magnetic property of permanent magnetic material.
