Abstract
The invention relates to a stator punching groove mould, comprising a first mould plate and a second mould plate, wherein a convex mould is arranged on the first mould plate, and a concave mould matched with the convex mould is arranged on the second mould plate; the convex mould comprises a locating convex mould which is used for punching a locating hole on a stator sheet body and a notch convex mould for punching the notches on the stator sheet body, a plurality of the notch convex moulds are arranged, the outermost ends of a plurality of the notch convex moulds are distributed along the same circumference, and at least two locating convex moulds are arranged at the outer side of the circumference in which the notch convex moulds are distributed. The stator punching groove mould has the advantages of good locating effect and high punching efficiency, and is simple in structure.
Description
Technical field
The present invention relates to a kind of stator jet-bedding mould.
Background technology
At present, the motor stator middle part offers the groove that is used to place stator coil, and stator is formed by the silicon steel sheet lamination usually.Therefore, this type of groove just forms when the punching press silicon steel sheet.
In the prior art, " one falls three " mode is adopted in the stator motor punching, after the punching press of silicon steel sheet profile, again with the flute profile punching press.Because profile and flute profile are the branch secondary centre of punch, both concentricitys are difficult to guarantee when carrying out lamination, and the wedging degree of flute profile also is difficult to guarantee, make punching laminate moulding after flute profile uneven, influence motor quality.
Summary of the invention
The invention provides a kind of stator jet-bedding mould.
For achieving the above object, the technical solution used in the present invention is:
A kind of stator jet-bedding mould, comprise first template and second template, described first template is provided with punch, described second template is provided with the die that is complementary with described punch, described punch comprises: be used for stator lamellar body upper punch press location hole the location punch, be used for the groove punch of groove on the punching press stator lamellar body, described groove punch is provided with a plurality of, and a plurality of described groove punch are along same circle distribution; Described location punch is provided with at least two, and described location punch is arranged on the periphery that is distributed of described groove punch.
Preferably, described location punch is provided with four.
Further preferably, four described location punch are arranged on four summits of circumscribed square of the circumference that described groove punch distributed.
Preferably, the diameter of described location punch is 8mm.
Stator jet-bedding mould of the present invention is applicable to the subpunch grooved, the processing technology of back punch extermal form, and by when the stator jet-bedding, additional punching press location hole makes stator when the separation punching press of carrying out next step, guarantees the consistent of twice punching press concentricity and flute profile by location hole.
Because the technique scheme utilization, the present invention compared with prior art has following advantage: the present invention is simple in structure, good positioning effect, the efficient height of punching press.

Embodiment
Below in conjunction with drawings and Examples the present invention is further described:
A kind of stator jet-bedding mould as shown in Figure 1, 2 comprises that first template 1 and second template, 2, the first templates 1 are provided with punch, second template 2 is provided with the die that is complementary with punch.
Wherein, punch comprises: be used for stator lamellar body 7 upper punches press location hole 9 location punch 3, be used for the groove punch 4 of groove 8 on the punching press stator lamellar body 7.How many groove punch 4 is provided with several according to the stator coil setting, and these groove punch 4 generally are Long Circle, and the outermost end of groove punch 4 is along same circle distribution, and same, its inner terminal is also along same circle distribution, and both centers of circle are concentric.
Locate die 5 and groove die 6 with first template, 1 corresponding being provided with on second template 2.
Below the concrete method of operation of present embodiment down of setting forth:
Processing stator lamellar body 7 as shown in Figure 5,4 stators of punching press on a slice stator lamellar body 7 in the present embodiment.Stator lamellar body 7 is placed in the groove die 6 of second template 2, as shown in Figure 3.Start 1, four location punch 3 of first template and a plurality of groove punch 4 and on stator lamellar body 7, go out 4 location holes 9 and several grooves 8 simultaneously, as shown in Figure 4.On a slice stator lamellar body 7, repeat 4 punching presses, go out stator lamellar body 7 as shown in Figure 5.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
