Description
Technical field
The utility model is related to magnetic shoe molding die technical field, and especially a kind of extrados is the forming magnetic tile of working face
Mould.
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 electric power magnetic to have lot of advantages, can make electric machine structure
Simply, easy to maintenance, lightweight, small volume, using reliable, copper consumption is few, copper loss is low, energy consumption is small etc..Outer arc working face magnetic shoe
In use, magnetic shoe working face is extrados, and extrados requires extrados magnetic more as a magnetic pole, such magnetic shoe
By force, magnetic flux density is higher.All it is that intrados magnetic field intensity is high because the magnetic shoe of conventional magnetic shoe mould production, is tested after magnetizing
In the magnetic field intensity of extrados respective point.Magnetic shoe manufacturing process is analyzed to understand, due to magnetic shoe it is compressing during, material granule
Orientation is needed, therefore alignment magnetic field by changing magnetic field orientating direction, can be concentrated on to the extrados of magnetic shoe, raising outer arc is reached
The purpose of face magnetic, this relates to magnetic shoe molding die, how mold design is changed, to reach required mesh
, it is the key for solving the problem.
Utility model content
The technical problems to be solved in the utility model is:In order to solve prior art mould in compacting outer arc working face
Magnetic shoe when, the problem of outer arc working face magnetic property of magnetic shoe is weaker, now provide a kind of extrados be working face forming magnetic tile
Mould, it is adaptable to multipair pole magnetic shoe.
The utility model solves the technical scheme that its technical problem used:A kind of extrados for working face magnetic shoe into
Pattern has, including upper die head, lower die head, cavity plate and the coil for magnetizing, demagnetizing, the upper die head, lower die head and cavity plate it
Between enclose forming cavity, the coil is located at the outside of die cavity, and the upper end of the lower die head is provided with every magnetosphere, described every magnetosphere
Upper surface is the arc surface caved inward, and the lower surface every magnetosphere is that two symmetrical lower inclined planes are crossed to form, institute
State lower inclined plane to be inclined upwardly from outside to inside, the common wire that two lower inclined planes are crossed to form is located at every the middle part of magnetosphere.
Thick every magnetosphere intermediate thin two ends in this programme, lower inclined plane is linearly inclined upwardly, and is located at two lower inclined planes every magnetosphere
Common wire at magnetic resistance it is most weak, every magnetosphere lower surface using two symmetrical lower inclined planes so that the whole magnetic every magnetosphere
Resistance is larger from two ends to the amplitude of intermediate change, reaches that the position magnetic resistance every common wire on magnetosphere is significantly smaller than every magnetosphere both sides
Magnetic resistance, converge, converged in a property to every magnetosphere common wire position so as to realize that the magnetic line of force of alignment magnetic field is a large amount of so that
The magnetocrystalline differently- oriented directivity of magnetic material tends to common wire, is conducive to the extrados middle part of magnetic shoe to form strong magnetic dot.
The material every magnetosphere is 7Mn15Cr2Al3V2WMo (nonmagnetic steel) or 1Cr18Ni9Ti (stainless steel).
The beneficial effects of the utility model are:Extrados of the present utility model causes magnetic for the magnetic shoe molding die of working face
Molecule is assembled towards the middle part of extrados, and the density and magnetic property for effectively raising magnetic shoe extrados intermediate point meet electricity
The characteristic of machine.

With can be only used for helping the description to the feature in accompanying drawing with reference to (for example, upper and lower, left and right, etc.).Therefore, not in limit
Detailed description below is used in property meaning processed, and only by appended claims and its equivalents are asked to limit
The scope of the theme of protection.
Embodiment 1
As shown in figure 1, a kind of extrados is the magnetic shoe molding die of working face, including upper die head 1, lower die head 2, cavity plate 3
And the coil 4 for magnetizing, demagnetizing, forming cavity is enclosed between upper die head 1, lower die head 2 and cavity plate 3, coil 4 is located at the outer of die cavity
Side, the upper end of lower die head 2 is provided with every magnetosphere 5, is the arc surface 501 caved inward every the upper surface of magnetosphere 5, every magnetosphere 5
Lower surface is that two symmetrical lower inclined planes 502 are crossed to form, and lower inclined plane 502 is inclined upwardly from outside to inside, two lower inclined planes
502 common wires 503 being crossed to form are located at every the middle of magnetosphere 5.
Every the material of magnetosphere 5 be 7Mn15Cr2Al3V2WMo or 1Cr18Ni9Ti.
Above-mentioned extrados is as follows using process for the magnetic shoe molding die of working face
Magnetic material (magnetic slurry) is put into die cavity, coil 4 is powered and magnetized, it is thick every the intermediate thin two ends of magnetosphere 5, it is oblique
