Description
Technical field
The invention belongs to the die apparatus field, particularly relate to a kind of ventilation duct mould.
Background technology
At present, because ventilation duct is " L " type structure, the ventilation duct mould die cavity of prior art also is " L " type structure, then during actual production, the end that blank is difficult for die cavity reaches the other end of die cavity, and then make blank can't carry out follow-up blowing program, make that whole production efficiency is lower, and then cause the production cost of ventilation duct higher.
Summary of the invention
The present invention is directed to above problem provides a kind of production efficiency higher, and then reduces the ventilation duct mould of the electric machine iron core of ventilation duct production cost.
The present invention overcomes the above problems used technical scheme: a kind of manufacture method of electric machine iron core is provided, and it may further comprise the steps: the 1) punch forming of iron core; 2) by the enlarging device stator rabbet on the punch forming iron core is carried out enlarging, make stator rabbet reach required notch size when winding the line; 3) iron core coiling; 4) iron core that coiling is finished carries out shaping, makes size when stator rabbet returns to punch forming.
Described enlarging device comprises upper bolster, discharging panel seat, stripper and enlarging punch; described enlarging punch upper end is slidingly connected on the discharging panel seat; the lower end of described discharging panel seat is connected with stripper; the end, lower end of described enlarging punch is positioned at the outside of stripper lower end, and described upper bolster lower end is provided with for promoting the slide block that the enlarging punch slides.
After adopting above method and apparatus, compared with prior art, the present invention is owing to carried out enlarging to stator rabbet, then when coiling, can wind the line by the stator rabbet after the enlarging, this is with regard to the magnetic flux of increment rate iron core, and the size when again the stator rabbet shaping being returned to firm punch forming after the coiling again, does not then influence the normal assembling of motor, thereby reach the purpose of the big magnetic flux of sulculus mouth iron core, and then make motor in performance bigger lifting be arranged.Therefore the present invention has and can wind the line by stator rabbet, and then promotes the characteristics of magnetic flux and motor performance.
As improvement, described discharging panel seat is provided with the resetting-mechanism that resets for the enlarging punch, after then resetting-mechanism arranges, makes the enlarging punch can be returned to initial position rapidly after enlarging, and then the operating efficiency of raising enlarging punch, the use cost of reduction equipment.
As further improvement, described resetting-mechanism comprises lead and the slide block that resets, the lower end of described lead is connected with the stripper upper surface, the described slide block slip cap that resets is connected on the lead, the upper end of described lead is provided with the annular stop piece to the cap slider position that resets, be provided with back-moving spring between the lower surface of the described slide block that resets and the stripper upper surface, the described slide block outer circumference surface that resets is provided with first inclined-plane, and the radius of the slide block lower end that resets is greater than the radius of the upper end of slide block that resets, described enlarging punch is provided with second inclined-plane of fitting with first inclined-plane, the resetting-mechanism of this structure then, and structure is simpler, parts are also less, preparation cost is lower, is pure frame for movement simultaneously, not by actuating unit, the reliability of using is higher, and stability is also better.
As further improving again, the lower surface of the described slide block that resets is provided with first counterbore, stripper upper surface under described first counterbore is provided with second counterbore, one end of described back-moving spring is against in first counterbore, the other end of back-moving spring is against in second counterbore, after this paired counterbore arranges, make the two ends of spring be limited in the counterbore, so in use, spring is not prone to the situation of displacement, and then the slide block that guarantees to reset has enough restoring forces the enlarging punch back into initial position, further stability and the reliability used of raising equipment, and reduce maintenance cost.
As further improving 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; the lower end surface of depression bar is fitted with the upper surface of the slide block that resets; then pressing down in the process at upper bolster, depression bar is also pushing away the slide block that resets to lower slider, and then feasible slip can promote the slip of enlarging punch more smoothly; and then reduce the active force that upper bolster presses down, thereby reach the purpose that cuts down the consumption of energy.
As further improving, the lower end of described slide block is provided with chamfering, one side of the nearly slide block of described enlarging punch is provided with the 3rd inclined-plane of fitting with chamfering, the then combination of inclined-plane and chamfering, the motion that makes slide block glide can be transformed into the translation of enlarging punch more smoothly, and be not prone to puckery situation of living between slide block and the enlarging punch, and then make the stability in use of equipment and reliability higher.
