Describe the stator punching 100 according to the utility model embodiment in detail below with reference to Fig. 1-Fig. 4, the stator wherein in motor is formed by stacking by multiple stator punching 100.
As depicted in figs. 1 and 2, stator punching 100 according to the utility model embodiment comprises: bent camber and have the punching section 1 of multiple winding slot 10, one end of punching section 1 is provided with draw-in groove 11 and the other end is provided with the buckle 12 coordinated with draw-in groove 11, and wherein stator punching 100 is spliced by the cooperation of one or more punching section 1 by buckle 12 and draw-in groove 11.Particularly, when stator punching 100 is spliced by a punching section 1, this punching section 1 is bent into arc and makes the draw-in groove 11 at two ends and buckle 12 coordinate to splice the stator punching 100 of an annular.When stator punching 100 is spliced by two punching sections 1, the buckle 12 of one of them punching section 1 and draw-in groove 11 can be coordinated with the draw-in groove 11 of another punching section 1 and buckle 12 stator punching 100 splicing an annular respectively, so analogize, when stator punching 100 is spliced by the punching section 1 of more than three and three, the punching section 1 of more than three or three successively head and the tail can be coordinated with the stator punching 100 splicing an annular.More specifically, by selecting the quantity of different punching sections 1, can splice the annular stator punching 100 of required different-diameter, different progression.
The processing method making stator punching 100 is as follows: as shown in Figure 3 and Figure 4, first, mould is adopted to become double separable stator tooth slot structure in every sheet rectangular patch prefabricated punching upper punch swaging, the sub-tooth slot structure that is often ranked limits the punching section 1 that has multiple winding slot 10, wherein as shown in Figure 3, if need two to be ranked between sub-tooth slot structure have certain gap, then adopt the mould that machining accuracy is lower, due to the impact of die cutter, the size in this gap is not less than the thickness of tooling blade.As shown in Figure 4, if need two to be ranked between sub-tooth slot structure not preset clearance, then the mould that machining accuracy is high is adopted.
Then one or more punching section 1 is joined end to end to splice stator punching 100.Wherein in order to improve the structural strength of the stator punching 100 splicing, the method for welding and/or injection moulding can be adopted to reinforce in the cooperation place of buckle 12 and draw-in groove 11.
Need to be described, as shown in Figure 1, the winding slot 10 of the stator punching 100 of this annular can be positioned on periphery wall, then correspondingly, the motor applying this stator punching 100 is external rotor electric machine.The winding slot 10 of the stator punching 100 of this annular can also be positioned on internal perisporium, then correspondingly, the motor applying this stator punching 100 is inner rotor motor.
According to the stator punching 100 of the utility model embodiment, be spliced into by the cooperation of buckle 12 and draw-in groove 11 by one or more punching section 1, thus be convenient to the machine-shaping of stator punching 100, improve the working (machining) efficiency of stator punching 100, simultaneously by selecting the punching section 1 of varying number, the demand of the motor of different seat No. can be met, reduce R&D costs, significantly shorten the research and development time.
Describe in detail according to the punching section 1 in the stator punching 100 of the utility model specific embodiment below with reference to Fig. 2.
As shown in Figure 2, on the length direction of punching section 1, one end of punching section 1 is provided with draw-in groove 11, and the other end of punching section 1 is provided with buckle 12, and the shape of buckle 12 is identical with the shape of draw-in groove 11.In order to avoid buckle 12 comes off in draw-in groove 11, the opening of draw-in groove 11 is narrowed gradually by Inside To Outside, wherein inner side refers to the direction towards buckle 12 on the length direction of punching section 1, and outside refers to the direction away from buckle 12 on the length direction of punching section 1.
On the direction from the opening of draw-in groove 11 to the diapire of draw-in groove 11, the opposing sidewalls of draw-in groove 11 is formed as the plane extended in direction surface thereof away from each other.Specifically, the opposing sidewalls of draw-in groove 11 is respectively the first plane 13 and the second plane 14, first plane 13 extends in the direction surface thereof away from the second plane 14, second plane 14 extends in the direction surface thereof away from the first plane 13, in other words, on the direction from the opening of draw-in groove 11 to the diapire of draw-in groove 11, the distance between the first plane 13 and the second plane 14 increases gradually, thus be not only convenient to the machine-shaping of draw-in groove 11, avoid buckle 12 to come off in draw-in groove 11 simultaneously.It is appreciated of course that, the shape of buckle 12 and draw-in groove 11 is not limited thereto, buckle 12 and draw-in groove 11 can also be formed as other shapes respectively, and the opposing sidewalls of such as draw-in groove 11 can be formed as arcwall face, as long as ensure that buckle 12 can coordinate with draw-in groove 11 and not easily come off in draw-in groove 11.
Punching section 1 comprises the yoke portion 15 of bent camber and the teeth portion 16 of multiple uniform intervals setting, on the first side wall that multiple teeth portion 16 is located at yoke portion 15 and two adjacent teeth portion 16 limit a winding slot 10, draw-in groove 11 and buckle 12 are located at the two ends in yoke portion 15 respectively.Thus by curved yoke portion 15 with the stator punching 100 making buckle 12 and draw-in groove 11 coordinate to splice annular.
Yoke portion 15 is provided with dashpot 17, dashpot 17 on the thickness direction in yoke portion 15, run through yoke portion 15 and the opening of dashpot 17 is positioned on second sidewall relative with the first side wall in yoke portion 15, in other words, the first side wall and the second sidewall are oppositely arranged, the opening of dashpot 17 is positioned on the second sidewall, and dashpot 17 also runs through yoke portion 15 in a thickness direction towards the first side wall is recessed.Thus by being provided with dashpot 17, the metal tension force that yoke portion 15 produces in bending process can be cushioned, reduce the deflection of punching section 1.
The number of dashpot 17 is five, and five dashpot 17 uniform intervals distributions on the length direction in yoke portion 15.Thus the metal tension force that yoke portion 15 produces in bending process can be cushioned further.Be understandable that, the number of dashpot 17 is not limited thereto, and the number of dashpot 17 can limit according to actual conditions.
Dashpot 17 comprises connected Part I 170 and Part II 171, Part I 170 is circular hole, Part II 171 is formed as the passage of the strip extended on the second sidewall, Part II 171 is bending to be extended, and the distance maximum between the opposing sidewalls of passage 171 is less than the diameter of Part I 170.Thus on the basis of buffering effect ensureing dashpot 17, be convenient to the machine-shaping of dashpot 17.It is appreciated of course that dashpot 17 can also be formed as other shapes, as long as the metal tension force cushioning yoke portion 15 and produce in bending process can be played.
In the utility model, unless otherwise clearly defined and limited, fisrt feature second feature " on " or D score can be that the first and second features directly contact, or the first and second features are by intermediary indirect contact.And, fisrt feature second feature " on ", " top " and " above " but fisrt feature directly over second feature or oblique upper, or only represent that fisrt feature level height is higher than second feature.Fisrt feature second feature " under ", " below " and " below " can be fisrt feature immediately below second feature or tiltedly below, or only represent that fisrt feature level height is less than second feature.
