Description
Technical field
The utility model relates to the process equipment of electric machine iron core, relates in particular to a kind of major diameter disc type electric machine iron core automatic processing device.
Background technology
Disc-type electric motor is a kind of axial field electric motor makes, has characteristics such as simple in structure, reliable, energy-conservation, easy to maintenance, is widely used in fields such as oil-field oil pumper, adjustable speed fan, hoist engine, lathe, mixer, rolling door.
The disc type electric machine iron core is a vitals in the disc-type electric motor, and it is the hollow cylinder that is rolled into silicon steel sheet band material, and at the following wire casing that equal indicative is radially arranged of hollow cylinder, the shape of following wire casing can be straight trough, skewed slot or helicla flute.
Up to now, disc type electric machine iron core automatic processing device is generally up-coiler and milling machine, its can make band material the limit trimming around in make and have the disc type electric machine iron core of wire casing down.The domestic existing small-sized disc type electric machine of tens tame plant produced, promptly power is less than the disc type electric machine of 5KW, and the production method of the disc type electric machine iron core that it adopts can reduce three kinds: the groove milling method of promptly reeling, jet-bedding coiling method and dash the volume combination method.
Coiling groove milling method is the electric machine iron core processing method of using the earliest, adopts the silicon steel sheet that up-coiler will the band material be rolled into hollow cylinder by size, radially mills time wire casing by the grooved dimensional requirement with milling machine at hollow cylinder.Though this method operation is easy, use equipment is simple.But there is fatal problem, low as production efficiency, can on cell wall, consider to be worth doing by residual a large amount of silicon steel in the milling process, when silicon steel bits are got in the interlayer that silicon steel sheet is rolled into, can have a strong impact on the lamination insulation between silicon steel sheet, cause bigger eddy current loss, cause the power of motor and other performance index that very big decline is all arranged.
Jet-bedding coiling method is improved a kind of method on the basis of coiling groove milling method, adopt up-coiler to be rolled into hollow cylinder by size with the silicon steel sheet of material, mill the location sulculus with milling machine afterwards, launch sulculus location, hollow cylinder utilization location then, on punch press, go out the slotted hole of the channel section size that rolls off the production line, with up-coiler band material with holes is wound into hollow cylinder again again, and the milling finishing.Because it is identical that the take-up force when reeling with the first time for the second time is difficult to, shape is uneven in the following wire casing that is rolled into, and needs finishing.So its eddy current loss is not thoroughly eliminated yet, production efficiency is still very low.
Dashing the volume combination method is to adopt the punching and the mode of carrying out synchronously of reeling to process the disc type electric machine iron core, it makes the hole that is dashed on the band material be aligned to radially following wire casing according to the alignment principle, be rolled into hollow cylinder, make following wire casing on the hollow cylinder in the first-class angular distribution of circumference, the feeding during punching is realized by winding mechanism.This kind method is widely used in the production of small-sized disc type electric machine now.This method has not only improved production efficiency, and reduced the eddy current loss of motor to a certain extent, but realize mechanism's complexity, frock is required height, can realize that in theory shape is neat in the motor slot, but in actual production process, because many-sided factor affecting such as machinery, often shape is irregular in Zhi Bei the electric machine iron core groove, and influence is the full rate of wire casing down, has objectively influenced the motor properties parameter.
The processing method and the equipment of at present traditional disc type electric machine iron core exist the error that can't eliminate in winding process, cause bigger eddy current loss, cause power of electric motor and other performance index that decline is all arranged, be only applicable to process the small-power disc type electric machine iron core of diameter＜600mm, can not satisfy the processing needs of the high-power disc type electric machine iron core of diameter＞600mm.Along with the fast development of major diameter disc type electric machine iron core in recent years, the research and development of major diameter disc type electric machine iron core automatic processing device have great economic worth.
