Technical field
The invention belongs to the equipment design field on permanent ferrite magnetic tile machining production line, specifically, it is related to
A kind of and magnetic shoe molding press device for studding with non-magnet_conductible material.
Background technology
Magnetic shoe is used primarily in permanent magnet DC motor, different by magnet exciting coil generation magnetic potential source from electromagnetic motor, forever
Magneto is to produce constant magnetic potential source with permanent-magnet material.Permanent magnetic tile replaces electrical excitation to have lot of advantages, can make electric machine structure
Simply, easy to maintenance, in light weight, small volume, using it is reliable, copper consumption is few, copper loss is low, energy consumption is small etc..Magnetic shoe generally uses iron oxygen
Body, neodymium iron boron, these three materials making of aluminium nickel cobalt, in the preamble of making, magnetic shoe slurry is in molding press device medium-pressure type and magnetizes,
Then machining processes are entered after demagnetizing.
Referring to Fig. 5, former magnetic shoe molding press device includes former upper mould 5, middle mould 2 and former drift 6.The former upper mould 5 and middle mould 2 are
Permeability magnetic material makes, and does not inlay non-magnet_conductible material.The former spill block of non-magnet_conductible material is inlayed in the upper end of the former drift 6
61, the shape of the former spill block 61 is this same tile of radian up and down, and thickness is 2~4mm.This method for embedding pressure
The magnetic shoe that type comes out, the magnetic line of force after magnetizing be in divergent state, intrados magnetic flux and the presence of extrados magnetic flux with a central point
Extreme difference, although can meet the use of motor, there is stomata in the magnetic shoe extrados of shaping, and reduces the density of magnetic shoe.
The content of the invention
There is the density that cavitations improve magnetic shoe to solve magnetic shoe extrados in shaping, the invention provides one kind
Stud with the magnetic shoe casted die mould of non-magnet_conductible material.
A kind of magnetic shoe molding press device for studding with non-magnet_conductible material, including upper mould 1, middle mould 2 and drift 3.The upper mould 1 is located at
The top position of middle mould 2, the middle mould 2 are provided with the pilot hole of 1~4 identical size, one are inserted upwardly into each pilot hole
Drift 3, magnetic shoe slurry are placed on the upper end of drift 3, and drift 3 is up, and magnetic shoe slurry is pressed into the tile with cambered surface, the dress
Magnetizer has been installed, and magnetic shoe base has been magnetized simultaneously.The downside of the upper mould 1 is provided with what two pieces non-magnet_conductible material made
Convex block 11, the downside of the convex block 11 are provided with convex cambered surface, and the upper end of the drift 3 is provided with what non-magnet_conductible material made
Spill block 31, the upper side of the spill block 31 are concavity cambered surface, and the concavity cambered surface and the convex of the downside of convex block 11
The radius of curvature of cambered surface is identical.
The technical scheme further limited is as follows：
The convex block 11 is connected with the connected mode of welding with upper mould 1, the center of convex block 11 and the pilot hole of middle mould 2
Center it is corresponding.
The downside of the spill block 31 is flat face.
The thickness of the convex block 11 is 5~12mm at the vertex position of convex cambered surface.
The thickness of the spill block 31 is 2~6mm in concavity cambered surface its lowest position.
The method have the benefit that：
(1) after mould and drift add the mosaic block of non-magnet_conductible material on, the cloth of original magnetic flux and the magnetic line of force is maintained
Put, stomata no longer occurs in the magnetic shoe after shaping.
(2) density of magnetic shoe is added, is compared with original process unit, the density of magnetic shoe, which has, original is less than 4.7g/
cm3Increase to and be more than 4.9g/cm3。
