Abstract
The invention relates to a stator and rotor punched sheet manufacture step by step craft. The stator and rotor punched sheet manufacture step by step craft adopts soil stock to feed materials automatically and comprises the following steps: (1) four pilot holes, a shaft hole ,a key groove, a buckle piece groove and all of the rotor groove profiles are punched; (2) a rotor punched sheet is punched: the rotor punched sheet is punched out by using the four pilot holes to positioning, and a stator inner circle is punched; (3) Coining the stator groove profiles: all of the stator profiles are punched by positioning by the four pilot holes; (4) Punching a stator punched sheet: the stator punched sheet is punched by positioning by the four pilot holes and punching a stator outer circle. The stator and rotor punched sheet manufacture step by step craft has the advantages of being capable of lowering production cost, improving operation security and being high in working efficiency. The stator and rotor punched sheet manufacture step by step craft is also applicable to small quantity production.
Description
Technical field
The invention belongs to the manufacturing field of generator, relate to a kind of rotor punching processing stepping technique, be particularly useful in batches little and generator stator-rotator punching that efficient is high of processing.
Background technology
The manufacturing procedure of electric machine rotor punching is the important procedure during motor is made.The punch machining process flow process of the existing electric machine rotor punching of generally using at present is as follows:
⑴ blanking: three (the dropping out stator cylindrical, stator inner circle, axis hole) that fall;
⑵ the compound punching of stator: go out again stator grooved, stator cylindrical, cramp groove with stator inner circle location;
⑶ the compound punching of rotor: go out again slot shape of rotor, axis hole keyway with the axis hole location.
But with this punch machining process punching out rotor punching the time, there are labour intensity height, inefficiency, the poor problem of processing safety.
Another kind of technique is to adopt progressive die production punching, and this technique can have the automatic stack pressure function, but a secondary progressive die high cost, the product that is applicable to produce in enormous quantities.
Summary of the invention
Problem to be solved by this invention is, overcome the deficiencies in the prior art, a kind of electric machine rotor sheet punching press processing technology is provided, adopt coiled strip self-feeding → rush again axis hole, keyway, slot shape of rotor, cramp groove → rush stator inner circle, go out rotor punching → rush again stator grooved → rush the stator cylindrical, go out stator punching.Reduced production cost, improved processing safety, high efficiency is applicable to be pilot production.
The present invention solves its technical problem and takes following technical scheme to realize:
According to rotor punching processing stepping technique provided by the invention, adopt the coiled strip self-feeding, it may further comprise the steps:
(1) four correcting holes of punching out, axis hole, keyway, cramp groove and all slot shape of rotors;
(2) go out rotor punching: with location, four correcting holes, rush the stator inner circle, go out rotor punching;
(3) stator grooved punching out: with location, four correcting holes, go out all stator grooveds;
(4) go out stator punching: with location, four correcting holes, rush the stator cylindrical, go out stator punching.
The present invention compared with prior art has significant advantage and beneficial effect:
Because the present invention adopts the coiled strip self-feeding, has improved production efficiency, reduced workman's labour intensity and improved the fail safe of producing; On die cost, greatly reduce than progressive die cost, be applicable to the production of be pilot.
The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to embodiment provided by the invention, structure, feature and effect thereof, be described in detail as follows.
A kind of electric machine rotor sheet punching press processing technology as shown in Figure 1 adopts coiled strip 9 self-feedings, and it may further comprise the steps:
(1) four correcting holes 1 of punching out, axis hole 5, keyway 4, cramp groove 2 and all slot shape of rotors 3, the structure of title compound schematic diagram as shown in Figure 2.
(2) go out rotor punching: with location, four correcting holes, rush stator inner circle 10, the structure of title compound schematic diagram goes out rotor punching 6 as shown in Figure 3, and the structure of title compound schematic diagram as shown in Figure 4.
(3) stator grooved punching out: with location, four correcting holes, go out all stator grooveds 7, the structure of title compound schematic diagram as shown in Figure 5.
(4) go out stator punching: with location, four correcting holes, rush stator cylindrical 11, gained waste material structural representation goes out stator punching 8 as shown in Figure 6, and the structure of title compound schematic diagram as shown in Figure 7.
Claims (1)
1. stepping technique is processed in a rotor punching, and it is characterized in that: adopt the coiled strip self-feeding, it may further comprise the steps:
(1) four correcting holes of punching out, axis hole, keyway, cramp groove and all slot shape of rotors;
(2) go out rotor punching: with location, four correcting holes, rush the stator inner circle, go out rotor punching;
