Abstract
The invention discloses a method for manufacturing a commutator copper segment, which is characterized by comprising the following steps: a. forming the body of the commutator copper segment, and forming embedding holes in the side direction of the body of the commutator copper segment; b. forming pins of the commuator copper segment, wherein each pin is provided with an embedding member of which the shape matches with that of the embedding hole; and c. mounting the embedding members of the pins into the embedding holes of the commutator copper segment, wherein the embedding members and the embedding holes are in interference fit, and the embedding members are expanded in the embedding holes. The method has an advantage of simple process. According to different strength requirements of the commutator, the pins of the commutator copper segment are independently and flexibly designed, and then the pins are combined with the body of the commutator copper segment. Not only is high strength requirement of the commutator better satisfied, but also universal design can be realized for the body and the pins of the commutator copper segment. The number of prepared molds is reduced and furthermore the pins of the commutator copper segment can be made of a material which is different from that of the commutator copper segment, thereby saving cost.
Description
[technical field]
The present invention relates to commutator manufacture technology field, be specifically related to the manufacture method of copper segment.
[background technology]
Commutator is applied on rotor, and the major part of commutator is exactly copper segment.The copper segment of prior art, be made up of body portion and hook part, lamellar body and hook are structure as a whole, for the commutator of dissimilar, different size, varying strength, the structure of its copper segment is all different, comprises the difference of lamellar body and the difference of hook, hook determines the bond strength of copper segment and commutator matrix, be equivalent to the mechanical strength determining commutator product, because lamellar body and hook are all different, so the punching die of copper segment will be equipped with a lot; Also have, because be disjunctor with lamellar body, so the design meeting critical constraints of hook, for ensureing the bond strength between copper segment and commutator matrix, it is comparatively large that hook often will design, and hook can only be same copper material with lamellar body, the material in addition on hook limit all want when hook is shaping punched fall, will cause larger spillage of material like this, cost is high.
[summary of the invention]
The present invention takes following technical scheme:
Copper segment manufacture method, is characterized in that comprising the following steps: the lamellar body of the shaping copper segment of a., and molds inlaid hole in the side surface direction of copper segment lamellar body; B. the hook of shaping copper segment, hook band insertion, the shape of insertion and the mating shapes of inlaid hole; C. loaded by the insertion of hook in the inlaid hole of lamellar body, insertion and inlaid hole interference fit, insertion swelling is in inlaid hole.
In step a, utilize the lamellar body of the shaping copper segment of drawing process drawing, utilize the inlaid hole of Sheet Metal Forming Technology punch forming copper segment lamellar body side surface direction.
In stepb, the hook of upsetting technique or pressure injection technique or the shaping copper segment of Sheet Metal Forming Technology is utilized.
The lamellar body of copper segment is copper material, and the hook of copper segment is high-strength nylon material or ferrous material.
After adopting technique scheme, the lamellar body of the first shaping copper segment of the present invention, and inlaid hole is molded on lamellar body, then the hook of independent flexible design copper segment is required according to commutator varying strength, and the hook of independent shaping copper segment on this basis, shaping hook band insertion, finally the insertion of hook is loaded in the inlaid hole of lamellar body, technique is simple, can better meet commutator requirement of strength, and the lamellar body of copper segment, hook can realize universal design, as long as combine, reduce mould to be equipped with, the hook of copper segment can select the material being different from lamellar body simultaneously, it is less that hook size also can design, do not need yet the material on hook limit when hook is shaping punched fall, cost-saving.
[accompanying drawing explanation]
The present invention has the following drawings:
Fig. 1 for utilizing the copper segment made by the technology of the present invention,
Fig. 2 is the Split type structure figure of Fig. 1,
Fig. 3 be Fig. 1 overlook directional diagram.
[embodiment]
As shown in the figure, utilize the copper segment made by the technology of the present invention, be made up of lamellar body 1 and upper and lower two hooks 4, the side surface direction of lamellar body 1 is provided with upper and lower inlaid hole 2, hook 4 is with insertion 3, the shape of insertion 3 and the mating shapes of inlaid hole 2, and the insertion 3 of hook 4 loads in the inlaid hole 2 of lamellar body 1, insertion 3 and inlaid hole 2 interference fit, insertion 3 swelling is in inlaid hole 2.
Copper segment manufacture method of the present invention, comprises the following steps: a. utilizes the lamellar body 1 of the shaping copper segment of drawing process drawing, and utilizes Sheet Metal Forming Technology to go out inlaid hole 2 at the side surface direction punch forming of copper segment lamellar body 1; B. the hook 4 of upsetting technique or pressure injection technique or the shaping copper segment of Sheet Metal Forming Technology is utilized, hook 4 is with insertion 3, the insertion 3 of hook 4 loads in the inlaid hole 2 of lamellar body 1 by the shape of insertion 3 and the mating shapes c. of inlaid hole 2, insertion 3 and inlaid hole 2 interference fit, insertion 3 swelling is in inlaid hole 2.
The lamellar body 1 of copper segment is copper material, the hook 4 of copper segment is high-strength nylon material or ferrous material, when the hook of copper segment is high-strength nylon material, it is shaping that hook can utilize pressure injection (injection moulding) technique, when the hook of copper segment is ferrous material, hook can utilize upsetting technique (when hook shape is more complicated) or Sheet Metal Forming Technology (when hook shape is simpler) to come shaping.
