Abstract
The utility model discloses a kind of double winding stator cores, are related to rotary electric machine iron core and its manufacturing field.Stator core is wound to certain shapes by two the same material strip superpositions and forms.The utility model improves the speed of production of traditional coiling process, reduces the usage quantity of coiling process device.
Description
Technical field
The utility model relates to rotary electric machine iron core and its manufacturing field more particularly to a kind of double winding stator iron
Core.
Background technique
Electric machine iron core is the important component of all kinds of motors, is the main composition of motor cost, and electric machine iron core is processed, I
70% or more state still uses traditional processing technology, i.e. (riveting) synthesis type is welded in punching --- closed assembly ---.The technique raw material
Utilization rate is low, such as disregards the recycling of corner, and utilization rate is only 20% or so.At beginning of the eighties late 1970s, existed before this
The U.S., after Japan, Italy etc. occur it is a kind of traditional thin plate block is substituted as raw material using thin plate strip, pass through punching tooth form
Steel band --- screw winding --- overlapping --- welding --- novel process of extrusion molding, referred to as " coiling process ", its advantage is that
Increase substantially stock utilization.But as mold rushes, speed is continuously improved, material strip columns is continuously increased, and a column are filled with a winding
Correspondence is set, the increase of winding device is caused when columns increases, traditional coiling process is unable to satisfy existing demand.
Therefore, those skilled in the art is dedicated to developing a kind of double winding stator core, to improve traditional wound work
The speed of production of skill reduces the usage quantity of coiling process device.
Utility model content
In view of the above drawbacks of the prior art, technical problem to be solved in the utility model is to improve traditional wound work
The speed of production of skill reduces the usage quantity of coiling process device.
To achieve the above object, the utility model provides a kind of double winding stator core.
In the better embodiment of the utility model, double winding stator core is by two identical material strip superposition windings
It is formed to certain shapes.
Further, the material strip of double winding stator core is steel band.
Further, the shape of winding is helical form.
The manufacturing method of double winding stator core described in the utility model, steps are as follows:
301, material strip is processed, forms the identical material strip of two column shapes；
302, two column material strips are superimposed, it is made to coincide together；
303, two column material strips are rolled up via winding apparatus to regulation shape simultaneously；
304, it is cut after reaching specific thickness, if not up to specific thickness, repeats step 303；
305 and entirety is formed by being fixedly connected with mode；
306, using shaping mechanical shaping, stator core is formed.
Further, the processing method of material strip is punching press.
Further, the material strip used is steel band.
Further, spiral helicine end face is concordant.
Further, mode is fixedly connected with as welding.
Further, mode is fixedly connected with as riveting.
Further, shaping machinery is press.
The utility model arranges equiform material strip by punching press two, carries out bilayer and winds simultaneously, reduces winding device, mention
The speed of production of high tradition coiling process, save the cost improve production efficiency, solve the problems, such as that existing production capacity is insufficient.
Make furtherly below with reference to technical effect of the attached drawing to the design of the utility model, specific structure and generation
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
Detailed description of the invention

Specific embodiment
Multiple preferred embodiments that the utility model is introduced below with reference to Figure of description, keep its technology contents clearer
Be easy to understand.The utility model can be emerged from by many various forms of embodiments, the protection of the utility model
Range is not limited only to the embodiment mentioned in text.
In the accompanying drawings, the identical component of structure is indicated with same numbers label, everywhere the similar component of structure or function with
Like numeral label indicates.The size and thickness of each component shown in the drawings are to be arbitrarily shown, and the utility model is not
Limit the size and thickness of each component.Apparent in order to make to illustrate, some places suitably exaggerate the thickness of component in attached drawing.
As shown in Figure 1, stator core 1 is made of 2 identical material strips 101, material strip 101 is steel band, is wound as helical form.
As shown in Fig. 2, stator core 1 has winding connector 102.
As shown in figure 3, stator core 1 forms multilayered structure through " coiling process ", to be formed by welding or riveting.Specific step
It is rapid as shown in Figure 4:
201, punching press is carried out to steel band, forms the two equiform material strips of column；
202, two column material strips are superimposed, it is made to coincide together；
203, two column material strips are rolled up via winding apparatus to helical form simultaneously；
204, it is cut after reaching specific thickness, if not up to specific thickness, repeats step 203；
205 and by welding or riveting to form entirety；
206, using press shaping, stator core is formed.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that this field ordinary skill without
It needs creative work according to the present utility model can conceive and makes many modifications and variations.Therefore, it is all in the art
Technical staff passes through logical analysis, reasoning, or a limited experiment according to the design of the utility model on the basis of existing technology can
It, all should be within the scope of protection determined by the claims with obtained technical solution.
