Description

Extrados is the magnetic shoe molding die of working face
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.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the schematic diagram for the magnetic shoe molding die that the utility model extrados is working face.
In figure:1st, upper die head, 2, lower die head, 3, cavity plate, 4, coil, 5, every magnetosphere, 501, arc surface, 502, lower inclined plane, 503rd, common wire, 6, magnetic shoe.
Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram, Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model, direction 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 Face 502 is linearly inclined upwardly, most weak every magnetic resistance of the magnetosphere 5 at the common wire 503 of two lower inclined planes 502, every under magnetosphere 5 Surface is using two symmetrical lower inclined planes 502 so that the whole amplitude every the magnetic resistance of magnetosphere 5 from two ends to intermediate change compared with Greatly, the position magnetic resistance reached every common wire 503 on magnetosphere 5 is significantly smaller than the magnetic resistance every the both sides of magnetosphere 5, so as to realize orientation magnetic The magnetic line of force of field is a large amount of to converge to every the position of common wire 503 of magnetosphere 5, is converged in a property, so that the magnetocrystalline of magnetic material Differently- oriented directivity tends to common wire 503, while hydraulic press applies pressure, is squeezed into the magnetic material in die cavity by upper die head 1 Reverse current is passed through in type, coil 4 so that the magnetic shoe 6 in die cavity demagnetizes.
Above-mentioned is enlightenment according to desirable embodiment of the present utility model, passes through above-mentioned description, relevant staff Various changes and amendments can be carried out in the range of without departing from this utility model technological thought completely.This practicality New technical scope is not limited to the content on specification, it is necessary to determine that its is technical according to right Scope.
