Abstract
The utility model discloses a kind of eccentric type magnetic core blank of applicable directional cutting, comprise magnetic core stem stem, magnetic core base plate and magnetic core limit leg, described magnetic core stem stem is divided into the first magnetic core stem stem and the second magnetic core stem stem, arrange one groove between described first magnetic core stem stem and the second magnetic core stem stem, described groove is the rectangular channel penetrating magnetic core base plate.The distance that the two ends of groove described in the utility model extend to magnetic core limit, both sides leg is that B, B are of a size of 1/3rd of magnetic core limit leg thickness.Blahk structure described in the utility model needs the distance of cutting short, and structure is thin, only needs to cut the connected position of magnetic core limit, two ends leg, can not cause a large amount of powder wastes.The utility model, because cutting is apart from short, decreases the wearing and tearing of cutting blade, simultaneously because cutting quantity is little, also reduces the risk that in cutting process, eccentric magnetic core edge bursts apart.
Description
Technical field
The utility model relates to core production manufacturing technology field, especially relates to a kind of technical field of eccentric type magnetic core blank of applicable directional cutting.
Background technology
In order to solve the problem on deformation of some eccentric structure magnetic core product, cutting integral workblank structure is generally adopted to produce to the method for eccentric type magnetic core processing at present.
As shown in Figure 1, for the eccentric magnetic core blank of traditional cutting-type, comprise magnetic core stem stem 1, magnetic core base plate 2 and magnetic core limit leg 3, the both ends of the surface of magnetic core stem stem 1 are designed to the cambered surface caved inward, as the location of cutting, cut direction is the dotted portion shown in Fig. 1, therefrom can find out, first the distance of this kind of structure needs cutting, structure is thick, and waste powder is serious, secondly also increases the wearing and tearing of cutting blade, simultaneously because cutting quantity is large, so easily cause the magnetic core edge cut into burst apart breakage, thus considerably increase manufacturing cost, need to be improved.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, applicant is through repeatedly putting into practice improvement, devise a kind of eccentric type magnetic core blank of applicable directional cutting, decrease amount of debris when blank being cut into two eccentric magnetic cores, and also reduce the risk that in cutting process, eccentric magnetic core edge bursts apart.
Technical scheme: in order to realize foregoing invention object, the technical scheme that the utility model adopts is: a kind of eccentric type magnetic core blank of applicable directional cutting, comprise magnetic core stem stem, magnetic core base plate and magnetic core limit leg, described magnetic core stem stem is divided into the first magnetic core stem stem and the second magnetic core stem stem, arrange one groove between described first magnetic core stem stem and the second magnetic core stem stem, described groove is the rectangular channel penetrating magnetic core base plate.
Further, in order to realize the effect of groove directional cutting, the width of rebate A of described groove is 1.5 ~ 3.0mm, and the distance C between described groove and the first magnetic core stem stem/the second magnetic core stem stem is 0.05 ~ 0.15mm.
Again further, the two ends of groove described in the utility model extend to the distance of magnetic core limit, both sides leg is that B, B are of a size of 1/3rd of magnetic core limit leg thickness.
Beneficial effect: compared with prior art, its beneficial effect is the utility model:
1, blahk structure described in the utility model needs the distance of cutting short, and structure is thin, only needs to cut the connected position of magnetic core limit, two ends leg, can not cause a large amount of powder wastes.
2, the utility model is because cutting is apart from short, decreases the wearing and tearing of cutting blade, simultaneously because cutting quantity is little, also reduces the risk that in cutting process, eccentric magnetic core edge bursts apart, adds the acceptance rate of product, saved many manufacturing costs.
Accompanying drawing explanation
Fig. 1 is the structural representation of the eccentric magnetic core blank of traditional cutting-type.
Fig. 2 is a kind of vertical view of new E FD magnetic core blahk structure.
Fig. 3 is the structural representation that the utility model groove runs through magnetic core base plate.
Embodiment
Below by a most preferred embodiment, the technical program is described in detail, but protection range of the present utility model is not limited to described embodiment.
As shown in Figure 1, the eccentric magnetic core blank of tradition cutting-type comprises magnetic core stem stem 1, magnetic core base plate 2 and magnetic core limit leg 3, described magnetic core limit leg 3 points is located at the both sides of magnetic core stem stem 1, and from figure, in magnetic core blank originally, magnetic core stem stem 1, magnetic core base plate 2 are overall structure.
As shown in Figure 2, an eccentric type magnetic core blank for applicable directional cutting, comprises magnetic core stem stem, magnetic core base plate 2 and magnetic core limit leg 3, described magnetic core stem stem is divided into the first magnetic core stem stem 1a and the second magnetic core stem stem 1b, arranges one groove 4 between described first magnetic core stem stem 1a and the second magnetic core stem stem 1b.The width of rebate A of described groove 4 is 1.5 ~ 3.0mm, and the distance C between described groove 4 and the first magnetic core stem stem 1a/ second magnetic core stem stem 1b is 0.05 ~ 0.15mm.The distance that the two ends of described groove 4 extend to magnetic core limit, both sides leg 3 is that B, B are of a size of 1/3rd of magnetic core limit leg 3 thickness.
As shown in Figure 3, groove 4 described in the utility model is for penetrating the rectangular channel of magnetic core base plate 2.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
