Description
Technical field
It the utility model is related to generator core stator processing engineering device technique field, and in particular to a kind of adjustable hair of radius
The compacting tool set of electric machine iron core stator.
Background technology
Most of conventional electric generators iron core stator is all to fold riveting using overall circular punching material to form, the manufacturing process
The stator unshakable in one's determination of manufacture, if produced using sonde-type coil winding machine, due to be stayed when coiling probe is moved in groove
There is the space that itself passes through, therefore copper factor can not be made too high, and because the headspace that to be popped one's head in coiling, core slots are opened
Mouth can be larger, and this can cause the torque pulsation of generator, influence motor performance.
" motor external stator with adjustable inner diameter and its manufacture method " disclosed in patent CN102710033B solves tradition
The problem of external stator motor stator-core punching utilization rate is low, and copper factor is low, and notch opening is big.The side of its first coiling after-condensation
Although method solves the problems, such as notch, but have the following disadvantages：
1st, it is complicated.Because outer stator of motor main yoke portion unshakable in one's determination is some pieces of structures stitched together, in split
Each winding and iron core in journey, it is the construction unit being separated from each other in addition to the part being coupled by secondary yoke portion, influences whether to flow
Magnetic flux through yoke portion, and secondary yoke portion is due to that will meet that the needs of bending tend not to be made too wide., should due to above reason be present
The magnetic property of stator structure is not so good as unshakable in one's determination with the tradition of material with size with it.
2nd, fastening, sizing are difficult after condensation.Consolidated after the technical scheme condensation that the patent is provided with hoop
It is fixed, even and after installing hoop additional its overall mechanical strength also not as good as the stator core of traditional scheme.
3rd, the program can not use the iron core of in the market commercialization.National standard is it has been specified that some fixed dimensions
Stator iron-core lamination, such iron-core lamination is normalized, seriation, commercialization, it is not necessary to remanufacture mould, Ke Yizhi
Purchase is connect, is a kind of precious resource.And the iron core that the program throws aside standardization does not have to need separately fabricated mould, can regard
For technical defect.
Utility model content
The purpose of this utility model is to solve the above problems, there is provided one kind is used to prepare the adjustable generator core of radius
The compacting tool set of stator.
In order to solve the above problems, the technical solution adopted in the utility model is as follows：
The adjustable generator core stator compacting tool set of radius, it is characterised in that including mold and lower mould, mold
Mutually fastened with lower mould, mold include the first ring-shaped base, vertically downward and annular configuration the first zigzag teeth portion, the
The ring-type diameter that one zigzag teeth portion is surrounded by is consistent with the yoke portion diameter to be suppressed stator unshakable in one's determination；Lower mould includes the second ring
Shape base, vertically upward and annular configuration the second zigzag teeth portion, the ring-type diameter and institute that the second zigzag teeth portion is surrounded by
The yoke portion diameter for suppressing stator unshakable in one's determination is consistent.
Optimization of the present utility model, the first zigzag teeth portion of mold and the second zigzag teeth portion of lower mould are mutually handed over
Mistake arrangement.
Further optimization, the first zigzag teeth portion of mold and the second zigzag teeth portion end of lower mould are along generator
The width of stator radial direction unshakable in one's determination accounts for 1/3rd of generator core stator yoke width to half.
Operation principle of the present utility model is：Refering to shown in Figure of description 2：
After generator core stator carries out winding technique, generator core stator yoke is pressed using compacting tool set
System.After generator core stator yoke embossing shape, following change occurs in generator core stator：
（1）Stator rabbet reduces, or even closure；
（2）Generator core stator outer diameter reduces, and the diminution degree is relevant with suppressed corrugated depth, and depth is got over
Greatly, it is bigger to reduce degree；
（3）Generator copper factor improves, because generator core stator yoke is pressed into wave-like, coiling in notch
Window area reduces, while coiling copper factor raises.
Compared with prior art, it is the advantages of the utility model：Stator core yoke portion is directly carried out using compacting tool set
Compacting, make stator core yoke portion that corrugated deformation occur, so that notch reduces, the big minor adjustment of diameter of stator bore.Utilize this reality
With the stator core prepared by new compacting tool set compared with the stator of conventional electric generators, notch phase can be selected before compacting
To big stator core, facilitate coiling；Notch, which reduces, after being suppressed using compacting tool set even makes closed slot, and copper factor can
Up to more than 90%；In the case where not changing Lamination mould, notch, diameter of stator bore size are adjustable, and flexibility is good.
