Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of manufacture method of core structure, specifically comprises the steps:
First, raw material as carrying out punching, steel plate materials are generated to arc punching.The structure of this arc punching as shown in Figure 3, has arc connecting portion 21 and protrudes from the tooth portion 22 on this arc connecting portion 21, wherein on arc connecting portion both sides end, is formed with the groove 23 of certain depth, is formed with protuberance 24 on corresponding end.Each arc punching can have a plurality of tooth portion, as at least two.
It should be noted that, when the punching of punching arc, can a punching form arc connecting portion and tooth portion, also can first punching form arc connecting portion, and then punching formation tooth portion, afterwards arc connecting portion and tooth portion are combined to the punching of formation arc.Concrete can be by welding or the mode such as grafting is carried out combination.What the mode of pegging graft was concrete can be on arc connecting portion, to form an inserting groove, and projecting teeth portion forms plug connector, then says that plug connector inserts in inserting groove.
Then, in vertical direction by least two the identical stacked generation arc of arc punching pieces.The structure of this arc piece as shown in Figure 4, there is arc connecting portion 31, tooth portion 32, be opened in arc connecting portion 31 1 ends, there is certain depth and the groove 33 extending along the length direction of arc piece and the protuberance 34 that protrudes from arc connecting portion 31 corresponding ends.Wherein, arc connecting portion 31, tooth portion 32, groove 33 and tooth portion 32 are respectively by arc connecting portion 21, tooth portion 22, groove 23 and the stacked generation of protuberance 24 of arc punching.
Afterwards, the arc piece of some (at least two) is spliced to generation core structure mutually.Concrete, be that the protuberance of arc piece is inserted in the groove of adjacent arc piece so that each arc piece is stitched together, form core structure as shown in Figure 5.Wherein, arc connecting portion 31 is spliced to form the yoke portion 41 of ring-type, and the tooth portion 32 of arc piece forms the tooth portion 42 of core structure.Wherein tooth portion 42 can be arc connecting portion 41 outstanding formation laterally, can be also arc connecting portion 41 outstanding formation to the inside.
In the utility model, can, according to the quantity of arc piece, determine the angle of arc connecting portion, so that the arc piece of some is spliced to form the ring-type yoke portion 41 shown in Fig. 5 mutually.
