Abstract
The utility model discloses a split type stator punching sheet comprising a punching sheet body formed by splicing twelve same stator blocks along the circumferential direction, wherein each stator block is provided with a groove and a protruding block which are the same in shape and size; each stator block is also provided with a fastening sheet groove, a support leg and at least a self-riveting rivet; and an included angle alpha formed by two side edges of each stator block is 30 degrees. Compared with the technology of the prior art, the split type stator punching sheet is advantageous in that in split type stator punching sheet manufacture processes, a raw material utilization rate can be greatly improved; if a large-scale punching sheet which cannot be made through one-step punching operation is encountered, the large-scale punching sheet can be divided into independent small punching sheets and then can be punched; and therefore production of large-scale stator punching sheets is made possible.
Description
Technical field
The utility model relates to a kind of stator punching, especially a kind of split type stator punching.
Background technology
The punching that present conventional motor stator core is used is the overall structure of circle or similar round, the punching of forming stator core also is that the one piece punching press is finished, use the technology of one piece punching production punching can cause the utilance of raw material silicon steel disc lower, also increased difficulty for producing large-scale punching simultaneously.
The utility model content
The purpose of this utility model is to provide a kind of split type stator punching, overcomes the lower shortcoming of raw material silicon steel disc utilance and produces the big difficulty of large-scale punching difficulty.
The utility model realizes that the technical scheme of above-mentioned purpose is: a kind of split type stator punching, comprise the punching body, described punching body is made up of 12 identical stator blocks together of amalgamation along the circumferential direction, described stator block is provided with a groove and a projection, the shape of described groove and projection, big or small identical, on stator block, also be provided with a cramp groove and a leg, also be provided with at least one on the stator block from the riveting rivet, the angle α between two sides of stator block is 30 °.
As the further setting of such scheme, described quantity from the riveting rivet is 7.
As the further setting of such scheme, also be provided with breach on the described stator block.
As the further setting of such scheme, the breach of adjacent two stator blocks forms louvre.
The beneficial effects of the utility model are: compared with prior art, producing punching of the present utility model can be improved raw-material utilance greatly, as run into the large-scale punching of can not a punching press making, then can be divided into independently little punching and carry out punching press, provide possibility for producing large-scale stator punching.

Fig. 1 is the structural representation of stator block of the present utility model;
Fig. 2 is structural representation of the present utility model.
Among the figure: stator block 1, groove 2, cramp groove 3, leg 4, from riveting rivet 5, projection 6, breach 7, louvre 8, punching body 10.
Embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
Embodiment:
As shown in Figure 1 and Figure 2, a kind of split type stator punching, comprise punching body 10, described punching body 10 is made up of 12 identical amalgamations along the circumferential direction stator block 1 together, described stator block 1 is provided with a groove 2 and a projection 6, the shape of described groove 2 and projection 6, big or small identical, on stator block 1, also be provided with a cramp groove 3 and a leg 4, also be provided with at least one on the stator block 1 from riveting rivet 5, the angle α between two sides of stator block 1 is 30 °.
Described quantity from riveting rivet 5 is 7.
Also be provided with breach 7 on the described stator block 1.
The breach 7 of adjacent two stator blocks 1 forms louvre 8.
