Abstract
The utility model discloses a generator or motor iron core. The whole core is formed through convex-concave matching buckle riveting of more than two core unit blocks at a root portion in a circumferential direction, a number of the core unit blocks is consistent with a number of charging coiling poles of the whole core, each core unit block has a same shape, grooves on the core unit blocks which are used for convex-concave matching are dovetail grooves, the core unit blocks are formed by laminating core unit punching sheets, each core unit punching sheet has a same shape, and grooves on the core unit punching sheets which are used for convex-concave matching are dovetail grooves. By utilizing the generator or motor iron core, under equal output power, more materials are saved during manufacturing of the generator or motor iron core, so a material utilization rate is effectively improved, and manufacturing cost is reduced to a certain degree.
Description
Technical field
The utility model relates to the parts of generator or motor, especially the iron core of generator or motor.
Background technology
The fabrication of iron core process of existing motor alternator for vehicle or motor is: obtain lamination with thin steel band material through punching press earlier, again several lamination alignment are stacked and rivet (i.e. folded riveting).In order to enhance productivity, several that arrange in length and breadth are set on secondary mould usually paste chip forming units, with a thin steel band material, or the thin steel band material that stacks of several piece, disposablely just stamp out a lot of individual laminations.Lamination is through blanking punched formation, because the lamination shape is special, thin steel band material shared ratio of surplus material after blanking punched is very big, and the stock utilization that ubiquity when causing present iron core to make is low, the cost problem of higher.
The utility model content
The purpose of this utility model provides and a kind ofly can improve stock utilization during fabrication, reduces the generator of manufacturing cost or the iron core of motor.
For realizing above-mentioned technical purpose, the utility model has newly designed the iron core of a kind of generator or motor, whole iron core by plural iron core unit piece at root along circumferentially forming by the convex-concave button riveting that matches, single iron core unit piece is formed by the folded riveting of iron core unit punching.
Be equivalent to original whole core stamping is several iron core unit punchings upwards cutting in week, elder generation's punching press obtains the iron core unit punching during manufacturing, then the folded riveting of iron core unit punching is become single iron core unit piece, at last again with the iron core unit piece at root along circumferentially by the convex-concave button riveting that matches, thereby obtain whole iron core.Like this, in the design of diel, just the shaping mould mutual dislocation of a plurality of iron core unit punchings can be arranged, in the hope of making lacking that vacant part tries one's best, make that the surplus material accounting on the strip of blanking punched back minimizes, thereby reach the purpose of economical with materials.
Further, the quantity of iron core unit piece is consistent with the quantity of the whole iron core charging coiling utmost point, i.e. each charging coiling extremely corresponding an iron core unit piece.Under the prerequisite that does not influence the iron core function, the iron core unit piece that whole iron core cuts into is more little, the more easy mutual dislocation setting of carrying out iron core unit punching shaping mould when the design of diel, more easy maximized economical with materials.
Further, the size shape of each iron core unit punching is identical, accordingly, the size shape of each the iron core unit piece after the folded riveting is also identical, under the prerequisite that does not influence the iron core function, the size shape of each iron core unit punching is identical, the more easy mutual dislocation setting of carrying out iron core unit punching shaping mould when the design of diel, more easy maximized economical with materials.
Further, the groove that matches in order to convex-concave in the iron core unit punching is dovetail groove, and is corresponding, and the groove that matches in order to convex-concave on the iron core unit piece after the folded riveting also is dovetail groove.Adopt the convex-concave of dovetail groove form to match embedding even, and be aided with the button riveting, to increase mechanical strength, guarantee product reliability.
Adopt structure of the present utility model, under the condition of equal power output, make the iron core of generator or motor make more economical with materials, effectively improved the utilance of material, can reduce manufacturing cost to a certain extent.

Fig. 3 is the structural representation of iron core finished product among the utility model embodiment.
Fig. 4 is thin firm automatic stamping blanking schematic diagram among the utility model embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
As Fig. 1, Fig. 2 and shown in Figure 3, the iron core of a kind of generator or motor, whole iron core 4 by plural iron core unit piece 2 root along circumferentially by convex-concave match the button riveting form, the quantity of iron core unit piece 2 is consistent with the quantity of the whole iron core 4 charging coiling utmost points, be each charging coiling extremely corresponding an iron core unit piece, the size shape of each iron core unit piece 2 is identical, and the groove 2a that matches in order to convex-concave on the iron core unit piece 2 is dovetail groove.
Single iron core unit piece 2 is formed by iron core unit punching 1 folded riveting, and the size shape of each iron core unit punching 1 is also identical accordingly, and the groove 1a that matches in order to convex-concave in the iron core unit punching 1 also is dovetail groove accordingly.
Adopt the convex-concave of dovetail groove form to match embedding even, and be aided with the button riveting, to increase mechanical strength, guaranteed reliability of products.
Under the prerequisite that does not influence the iron core function, iron core unit piece, iron core unit punching that whole iron core 4 cuts into are more little, and make the size shape of each iron core unit piece, iron core unit punching identical, the more easy mutual dislocation setting of when the design of diel, carrying out iron core unit punching shaping mould, just more easy maximized economical with materials.
During manufacturing, elder generation's punching press obtains iron core unit punching shown in Figure 1, then the folded riveting of iron core unit punching is become single iron core unit piece shown in Figure 2, at last again with the iron core unit piece at root along circumferentially by the convex-concave button riveting that matches, thereby obtain whole iron core shown in Figure 3.Like this, in the design of diel, just the shaping mould mutual dislocation of a plurality of iron core unit punchings can be arranged, as shown in Figure 4, make lacking that vacant part tries one's best, surplus material accounting on the strip 3 of blanking punched back minimizes, thereby reaches the purpose of economical with materials, and reduces manufacturing cost to a certain extent, technology is simple, does not influence the iron core end properties.
