Abstract
The invention discloses a method for manufacturing a motor core. The method comprises the following steps 1) performing punch forming on the core; 2) flaring a stator slot on the core subjected to the punch forming by using a flaring device, so that the stator slot has the size to meet the requirement of winding; 3) winding the core; 4) shaping the core subjected to winding, so that the stator slot recovers the size during punch forming. Compared with the prior art, the method has the advantages that the stator slot is flared and winding can be carried out through the flared stator slot, so that the magnetic flux of the core is increased; and after winding, the stator slot is shaped to recover the size during punch forming, so that the normal assembly of a motor is not influenced, an aim that a small-slot core has high magnetic flux is fulfilled, and the performance of the motor is greatly improved. Therefore, the method has the characteristic of improving the magnetic flux and the performance of the motor by winding through the stator slot.
Description
Technical field
The present invention relates to a kind of manufacture method of electric machine iron core.
Background technology
At present, the electric machine iron core of prior art is after punch forming, all need to carry out coiling process, but because stator rabbet is relatively little, cannot coiling process be carried out, then be difficult to the magnetic flux promoting iron core on existing basis, therefore also just cannot the performance of lifting motor, if and stator rabbet is washed into large notch on the contrary coiling rear motor performance do not reach designing requirement again, therefore prior art exist cannot to stator rabbet coiling, the problem that magnetic flux and motor cannot promote.
Summary of the invention
The present invention is directed to above problem and provide a kind of by stator rabbet coiling, and then the manufacture method of the electric machine iron core of lifting magnetic flux and motor performance.
The present invention overcomes the above problems technical scheme used: the manufacture method providing a kind of electric machine iron core, and it comprises the following steps: the 1) punch forming of iron core; 2) by expanding device, enlarging is carried out to the stator rabbet on punch forming iron core, required notch size when making stator rabbet reach coiling; 3) iron core winding; 4) shaping is carried out to the iron core that coiling completes, size when making stator rabbet return to punch forming.
Described expanding device comprises upper bolster, discharging panel seat, stripper and enlarging punch; described enlarging punch upper end is slidably connected on discharging panel seat; the lower end of described discharging panel seat is connected with stripper; the lower end of described enlarging punch is positioned at the outside of stripper lower end, and described upper bolster lower end is provided with the slide block slided for promoting enlarging punch.
After adopting above method and apparatus, compared with prior art, the present invention is owing to having carried out enlarging to stator rabbet, then can carry out coiling by the stator rabbet after enlarging when coiling, this is with regard to the magnetic flux of increment rate iron core, and size when again stator rabbet shaping being returned to firm punch forming again after coiling, then do not affect the normal assembling of motor, thus reach the object of the large magnetic flux of small-rabbet iron core, and then make motor in performance, have larger lifting.Therefore the present invention has by stator rabbet coiling, and then promotes the feature of magnetic flux and motor performance.
As improvement, described discharging panel seat is provided with the resetting device resetted for enlarging punch, then, after resetting device is arranged, make enlarging punch can be returned to initial position rapidly after enlarging, and then improve the operating efficiency of enlarging punch, reduce the use cost of equipment.
As further improvement, described resetting device comprises lead and reset slide block, the lower end of described lead is connected with stripper upper surface, described reset skid is socketed on lead, the upper end of described lead is provided with the annular stop block to reset cap slider position, back-moving spring is provided with between the lower surface of described reset slide block and stripper upper surface, described reset slide block outer circumference surface is provided with the first inclined-plane, and the radius of reset slide block lower end is greater than the radius of reset upper end of slide block, described enlarging punch is provided with second inclined-plane of fitting with the first inclined-plane, the then resetting device of this structure, structure is simpler, parts are also less, preparation cost is lower, be pure mechanical structure simultaneously, not by actuating unit, the reliability used is higher, stability is also better.
As improving further again, the lower surface of described reset slide block is provided with the first counterbore, stripper upper surface immediately below the first described counterbore is provided with the second counterbore, one end of described back-moving spring is against in the first counterbore, the other end of back-moving spring is against in the second counterbore, after this paired counterbore is arranged, the two ends of spring are made to be limited in counterbore, therefore in use, not easily there is situation about being shifted in spring, and then ensure that reset slide block has enough restoring forces and enlarging punch is back into initial position, the stability of further raising equipment use and reliability, and reduce maintenance cost.
As improving further again; the lower end of described upper bolster is provided with depression bar; the upper end of described depression bar is connected with upper bolster; fit in the lower end surface of depression bar and the upper surface of reset slide block; then pressing down in process at upper bolster, depression bar also pushes reset slide block slide downward, and then makes slip can promote the slip of enlarging punch more smoothly; and then the active force that reduction upper bolster presses down, thus reach the object reducing energy consumption.
As further improving, the lower end of described slide block is provided with chamfering, the side of the described nearly slide block of enlarging punch is provided with the 3rd inclined-plane of fitting with chamfering, the then combination of inclined-plane and chamfering, the motion that slide block is glided can be transformed into the translation of enlarging punch more smoothly, and not easily occur between slide block and enlarging punch puckery live situation, and then make the stability in use of equipment and reliability higher.
