Specific embodiment
The present invention will be further described below with reference to the drawings.
Embodiment 1: a kind of manufacturing method of wave-wound coil stator core as shown in Figure 1, including insert insulating paper process, around
Waveform coil process processed, waveform coil insertion mold core process, mold core coil are pressed into stator core process, unloading stator core work
Sequence, fixed waveform coil process.Firstly, cutting out, bending insulating paper, match the shape of insulating paper with groove body cavity shape,
Insulating paper is inserted into the groove body of iron core；In order to improve efficiency, mold I can be set, the insulating paper after cutting out, bending is put
In mold I, using mold I, insulating paper is disposably pushed into groove body, insulating paper slides, falls off in order to prevent, is insulating
Adhesive is set between paper and groove body inner cavity, makes to be close between insulating paper and groove body inner cavity.Then, coiling waveform coil, need
It wants the stator conductor of coiling to turn to S-shaped wavy line, the waveform quantity of coiling is determined according to the number of plies of iron core slot number and coiling
And length；By taking 96 channel cores as an example, stator conductor is first by 12 conducting wires and train wave is around for S-shaped, the intermediate body portion of wavy line
For straight line portion, the length of straight line portion is greater than the length of stator groove body, can be so curved coupling part there are space,
It is set as curved coupling part at the both ends of straight line portion, both ends interconnecting piece can be V-arrangement or U-shaped or arc.In coiling,
Each layer needs 8 waveforms of coiling, and 4 layers of setting in each groove body needs 32 coils of continuous coiling altogether in this way；It, can also when coiling
With around being made as two groups, every 6 conducting wires are one group, wave around when, the intermediate host straight line portion conducting wire of adjacent wavy line is non-
In same plane, the intermediate host straight line portion for the wavy line being separated by can be two groups of sinuous lead wires in the same plane in this way
Mutually embedding two groups of S-shaped sinuous lead wires are respectively formed wave crest and trough there are space, then the wherein trough of one group of wavy line and another
The wave crest of one group of wavy line is opposite, keeps two groups of sinuous lead wires mutually embedding mutually, can thus be formed and be formed side by side by 12 conducting wires
S-shaped wave is around conducting wire.
Then, it carries out waveform coil and is embedded in mold core process, first mold core is placed on winding device, turning to waveform
Winding wire is rolled into cylindrical mold core, and Winding Layer is 4 layers；A mold core coil indentation stator core process is carried out again,
In this process, first stator core is put into mold II, positioned, fixed, mold core is then put into stator core
Centre is also positioned, is fixed, and the slot number of cylindrical mold core and the slot number of stator core are equal, and position is corresponding, even if
The notch that conducting wire is placed in mold core is opposite with stator core notch, pressing mechanism is recycled, the conducting wire in mold core in circumferential side
To conducting wire is pushed around from inside to outside, the sinuous lead wire in mold core is squeezed out, and is pushed away from the groove body opening of stator core
It is pressed onto the groove body of stator core；It, can be disposably all successively push of the waveform winding wire in mold core by this process
Quick in this way, conveniently into the groove body of stator core, safety is good, does not need to be welded, production efficiency can be improved, lead
Line is not in the bad phenomenons such as broken string, and the product quality of production is high.The slot of iron core is all pressed into the winding wire of waveform
After in vivo, then unloading stator core, pressing mechanism is resetted, the fixing piece of fixed mold core is unclamped, mold core from stator core
It removes, and removes stator core out of mold II；Finally, fixed waveform coil, in the groove body opening of stator core, setting is solid
Determine part to be fixed in the groove body of iron core waveform coil, prevents waveform coil from occurring loosening in the groove body of iron core or slide, such as
Slotted wedge paper is set in the groove body opening of stator core, can prevent conducting wire from sliding from groove body opening in this way.
Embodiment 2: other steps are same as Example 1, but in step C, in order to preferably the line for turning to waveform
Circle conducting wire is rolled into cylindrical mold core, and flat plate mold can first be arranged, the winding wire for turning to waveform is embedded into flat
In board mold, the sinuous lead wire for turning to S-shaped is embedded into flat plate mold according to the sequence of conducting wire, then in flat plate mold
Sinuous lead wire be rolled into cylindrical mold core, installation in this way is more convenient, and the speed that is involved in of conducting wire can be improved, further mention
The production efficiency of high stator.
Embodiment 3: other steps are identical as embodiment 1, embodiment 2, but after the completion of the manufacture of wave-wound coil stator core,
In fixed waveform coil process, the stator core for having completed wave-wound coil is placed in mold III, is set in mold III
Wire squeezes mechanism is set, protrusion is set in wire squeezes mechanism, using the protrusion in wire squeezes mechanism, in groove body
Outermost conducting wire squeezed, so that outermost conducting wire is locally generated deformation, form protrusion, generate and squeeze with groove body side wall
Pressure, has the function that fixed, in this way, can be further improved the production efficiency of stator, improves the quality of stator.
Embodiment of the present invention is explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned embodiment party
Formula can also make several variations and modifications to those skilled in the art under the premise of not departing from the present invention, this
It also should be regarded as belonging to the scope of protection of the present invention a bit.
