Abstract
The invention relates to a rotor sheet die which comprises a first template and a second template. The first template is provided with a convex die, and the second template is provided with a concave die matched with the convex die; the convex die comprises a groove convex die used for stamping grooves on a rotor sheet and a shaft hole convex die used for stamping a shaft hole on the rotor sheet; the groove convex die comprises first groove convex dies and second groove convex dies, wherein a plurality of groove convex dies are distributed along a first circumference, a plurality of second convex dies are distributed along a second circumference, the diameter of the first circumference is larger than the diameter of the second circumference, and the first groove convex dies and the second groove convex dies are connected through connecting parts. The invention has the advantage of simple structure, and the grooves of the stamped rotor sheet can benefit the assembly of leads.
Description
Technical field
The present invention relates to a kind of rotor punching mould.
Background technology
At present, the rotor middle part offers the groove that is used to place lead loop, and identical with stator, rotor also is to be formed by the silicon steel sheet lamination usually.Therefore, this type of groove is stamped out when the punching press silicon steel sheet.The groove of present rotor lamellar body generally is Long Circle, but when lead was installed, lead and insulating paper all were installed in the groove, often because groove is bigger, causes insulating paper to fit.
Summary of the invention
The invention provides a kind of rotor punching mould.
For achieving the above object, the technical solution used in the present invention is:
A kind of rotor punching 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: the groove punch that is used for groove on the stamping rotor lamellar body, the axis hole punch that is used for stamping rotor lamellar body upper shaft hole, described groove punch comprises the first groove punch, the second groove punch, a plurality of described first groove punch are along first circle distribution, a plurality of described second groove punch are along second circle distribution, the diameter of described first circumference is greater than the diameter of described second circumference, and the described first groove punch is connected by connecting portion with the second groove punch.
Preferably, be provided with the 3rd groove punch between two described first groove punch, a plurality of described the 3rd groove punch are along first circle distribution.
Further preferably, the described first groove punch is identical with the 3rd groove punch.
Preferably, described axis hole punch around be distributed with a plurality of line hole punch that are used for stamping rotor lamellar body upward wiring hole.
Because the technique scheme utilization, the present invention compared with prior art has following advantage: the present invention is simple in structure, and the groove of the rotor lamellar body of punching press can better be installed lead.

Embodiment
Below in conjunction with drawings and Examples the present invention is further described:
A kind of rotor punching mould shown in Fig. 1～6 comprises first template 1 and second template 2.Wherein: first template 1 is provided with punch, second template 2 is provided with the die that is complementary with punch.
Punch comprises: be used for groove on the stamping rotor lamellar body 10 groove punch 3, be used for the axis hole punch 4 of stamping rotor lamellar body 10 upper shaft holes.Wherein: groove punch 3 comprises the first groove punch 5, the second groove punch 6, the first a plurality of groove punch 5 are along first circle distribution, a plurality of second groove punch 6 are along second circle distribution, simultaneously, the diameter of first circumference is greater than the diameter of second circumference, and such first groove punch 5 just is arranged on the outside of the second groove punch 6.The first groove punch 5 is connected by connecting portion 8 with the second groove punch 6, and its three is become one.In addition, in the present embodiment, two first 5 of groove punch are provided with the 3rd groove punch 7, and a plurality of the 3rd groove punch 7 are too along first circle distribution, same the 3rd groove punch 7 can with the 5 identical settings of the first groove punch.
Around axis hole punch 4, be distributed with a plurality of line hole punch 9 that are used for stamping rotor lamellar body 10 upward wiring holes.
Be complementary with punch, the die on second template 2 is provided with groove die 30, axis hole die 40 and line hole die 90 equally.
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.
