Summary of the invention
Embodiment of the present invention technical problem to be solved is: a kind of rotor insulating paper is provided, is convenient to the follow-up manufacture craft of rotor, enhance productivity.
The embodiment of the present invention the technical problem that will further solve be: a kind of manufacture method of rotor insulating paper is provided, is formed with seeker on insulating paper.
For solving the problems of the technologies described above, the embodiment of the present invention adopts following technical scheme: a kind of manufacture method of rotor insulating paper comprises the steps:
The impression trace: with extrusion mechanism extruding insulation paper tape, the technique impression of frictional resistance between extruding in order to reinforced insulation paper and rotor core wire casing on insulating paper strip;
Rush seeker: go out on being pressed with the insulating paper strip of impression with punching mechanism in order to the seeker in the gap between leader film insertion flanging and rotor core wire casing;
Cut off: cut off insulating paper strip with shut-off mechanism and generate the semi-finished product insulating paper;
Punch forming: the moulding of semi-finished product insulating paper pressing and bending, namely obtain the finished product insulating paper.
For further solving the problems of the technologies described above, the embodiment of the present invention adopts following technical scheme: a kind of rotor insulating paper, comprise that body reaches the flanging from the long side bending formation of body, described rotor insulating paper also comprises in order to leader film and inserts seeker in gap between flanging and rotor core wire casing, and described seeker comprises the guide portion that the short brink one extension from flanging forms.
Further, described seeker also comprises the support portion of leaning on flanging place's extension and being connected with the guide portion one from the body short brink.
The beneficial effect of the embodiment of the present invention is: compared to existing technology, owing to being provided with seeker on rotor insulating paper, make the follow-up slotting film technique of rotor core carry out smoothly, both facilitated follow-up technique, improved again rotor production efficiency.
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail.

Embodiment
To shown in Figure 6, the embodiment of the present invention provides a kind of rotor insulating paper and preparation method thereof as Fig. 4.
As Fig. 4, the manufacture method of described rotor insulating paper comprises:
Wherein, the step of impression trace is for preventing that insulating paper 1 from coming off, due to insulating paper 1 be arranged on the wire casing 21 of rotor core 2 interior after, also will be on rotor core 2 installing insulating glue core 3, so stamp the frictional resistance that the technique impression increases insulating paper 1 and wire casing 21 inwalls on insulating paper 1.
As Fig. 5, after Cutting process, generate semi-finished product insulating paper 1, it comprises the breach 14 of body 11, seeker 12, flanging 13 and excision.Impression not shown in the figures, the length of body 11 is predetermined length D, because the length of rotor core 2 is D1, the thickness of insulated rubber core 3 is D2, so facilitate in order to insulate and wind the line, requires D≤D1+2D2, and D〉D1.The length of seeker 12 is not limit, and protruding suitably, distance gets final product.So the total length of semi-finished product insulating paper 1 is greater than D, after guaranteeing excision breach 14, retaining on semi-finished product insulating paper 1 has seeker 12.
As Fig. 6, after punch forming process, generate finished product insulating paper 1, it comprises body 11, seeker 12, flanging 13 and V-type groove 15.Body 11 is after the pressing and bending moulding process, and its profile is as figure V font, is complementary with the V font wire casing 21 of described rotor core 2, and the length of body 11 is constant; Described seeker 12 is positioned at the front end of body 11, and described flanging 13 is formed by the long side bending of body 11, is positioned at the top of finished product insulating paper 1; Described seeker 12 comprises from the short brink one of flanging 13 and extends the guide portion 121 that forms, and also comprises the support portion 122 of extending and being connected with guide portion 121 one by flanging 13 places from body 11 short brinks.
As Fig. 7, when film is installed, film 5 is driven by inserted sheet cutter 5 in the wire casing 21 that inserts rotor cores 2, and due to the existence of seeker 12, film 5 is with before insulated rubber core 3 contacts, the seeker 12 that is insulated paper 1 supports, and be inserted into smoothly in wire casing 21 along the upper end of flanging 13, be positioned at flanging 13 and the gap that wire casing 21 forms, avoided film 5 immediate roofs on the end face of insulated rubber core 3, perhaps be inserted in the V-type groove 15 of insulating paper 1, and have influence on the installation of film 5.
In sum, embodiment of the present invention rotor insulating paper and preparation method thereof owing to being provided with seeker 12 on insulating paper 1, makes the follow-up slotting film technique of rotor carry out smoothly, has both facilitated follow-up technique, has improved again production efficiency.
The above is the specific embodiment of the present invention; should be pointed out that the general expression technical staff for the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also are considered as protection scope of the present invention.
