Compared with the prior art, the method has the advantages of high material utilization rate, simple equipment and small occupied area.
Description
Technical field
The present invention relates to motor stator core, be specifically related to a kind of manufacture method of disk type motor stator core.
Background technology
The stator core of conventional motors is to sweep away circular punching on electric steel plate, punching is formed by stacking again, and this iron core has following deficiency:
1, stock utilization is low.Because electric steel plate dispatches from the factory and is generally the cylindrical steel roll form, add and earlier coil of strip is cut into the rectangle steel plate man-hour, on sheet steel, go out circular punching then, this mode of production must cause stock utilization low.With the electric steel plate upper punch external diameter of 200mm * 640mm is that 100 punching is example (going out the rotor punching simultaneously), and the utilance of material only is about 65%;
2, the motor axial length is longer, is unfavorable for saving the space, and the motor complicated integral structure, is unfavorable for maintaining;
3, be unfavorable for heat radiation, be difficult to improve power density.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of stock utilization height, the manufacture method of the disk type motor stator core that equipment is simple, area occupied is little for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: a kind of manufacture method of disk type motor stator core, it is characterized in that, this method is the electrical sheet winding that band shape electrical sheet is processed into certain width, be installed on the take-off reel of slotting winding machine tool, take-off reel is regularly sent the electrical sheet winding to feeding table, by feeding table stamping die is sent in the electrical sheet winding and gone out flute profile, the electrical sheet winding of having dashed after the flute profile is wound into the iron core dish on closed reel, the iron core dish that processes unloads from closed reel, flatten on the tooling platform then, the welding footing is promptly finished the production of product.
Described iron core dish top is provided with welding machine, and this welding machine is in the head part that goes out that closed reel begins to reel and reel when finishing fixedly electrical sheet winding, makes the iron core dish indeformable when closed reel unloads.
Described iron core dish below is provided with jig, and this jig makes the flute profile alignment on the iron core dish, and the driving fuselage moves down along guide rail with the increase of iron core dish radius.
Described iron core dish back is provided with fuselage, and this fuselage is used for the gravity of balance fuselage.
Described fuselage connects cylinder, and is provided with operation panel between fuselage and cylinder.
Described operation panel is the control board of operation slotting winding machine tool.
Compared with prior art, the present invention has advantage:
1, adopt the inventive method to produce disk type motor stator core stock utilization height.What this method was used is banded electrical sheet, each iron core by a complete steel coil strip around forming, its shape just in time shape with former electrician's coil of strip is consistent, can as the conventional motors punching, can't not utilize four jiaos clout, theoretically, the utilization rate of raw materials of this product can reach 100%, and promptly all parts of former coil of strip can effectively be utilized;
2, the profile of the disc type electric machine stator of employing the inventive method production is in the form of annular discs, and corresponding motor is also in the form of annular discs, and such motor has the short characteristics of axial length, and conditional occasion can be given full play to its effect in a lot of spaces.And the overall structure of motor is very simple, is beneficial to maintaining;
3, the winding of disc type stator is embedded in the surface of iron core, is open distribution, and area of dissipation is very big, compares with the conventional motors with power, and this motor can make volume-diminished 40% under same temperature condition.
