Abstract
The utility model discloses a kind of E type magnetic ferrite magnetic core, aiming to provide a kind ofly does not increase cost and does not affect the E type magnetic ferrite magnetic core of performance.It comprises base and three pillars, and three described pillars are evenly arranged on base, and the shape of its cross section is E type, and described pillar and base are integrated, and the end face of described three pillars is provided with some projections, and the shape of described projection is hemisphere.The beneficial effects of the utility model are: projection can recycling, does not increase production cost, does not affect performance, be applicable to the E type soft ferrite magnetic core products that overall length dimension is greater than 20mm, and structure is simple, easy to operate.
Description
Technical field
The utility model relates to soft magnetic ferrite correlative technology field, refers in particular to a kind of E type magnetic ferrite magnetic core.
Background technology
Magnetic ferrite magnetic core is the original paper or part made with soft magnetic ferrite, and its shape is determined by mould substantially, and mould carries out design and manufaction according to the shape of magnetic core.E type magnetic ferrite magnetic core, the magnetic ferrite magnetic core of its to be shape of cross section be E type.
Major part produces house when producing this type product, consider that this product all can gather into folds sintering by production cost and production efficiency up and down, after sintering like this, upper and lower two products meeting adhesion, be separated time can make product occur arrisdefect phenomenon (on smooth face, there is larger breach, and this breach add at mill cannot remove man-hour).For this phenomenon, everybody can adopt following methods to solve: on the contact-making surface of two products, sprinkle Powdered article.1., aluminium oxide Powdered article are divided into two classes usually according to its main component; 2., zirconia.
And when adopting the powder of above heterogeneity, different impacts can be produced in process of production: 1. alumina powder: this powder can react with soft magnetic ferrite principal component zinc oxide in sintering process, and then affects its electric property and mechanical performance; 2. zirconia powder: this powder unit price is high, and be unfavorable for reclaiming, cause production cost to raise.
Utility model content
The utility model there is above-mentioned deficiency to overcome in prior art, and providing a kind ofly does not increase cost and do not affect the E type magnetic ferrite magnetic core of performance.
To achieve these goals, the utility model is by the following technical solutions:
A kind of E type magnetic ferrite magnetic core, comprise base and three pillars, three described pillars are evenly arranged on base, the shape of its cross section is E type, described pillar and base are integrated, and the end face of described three pillars is provided with some projections, and the shape of described projection is hemisphere.
Projection can be regularly arranged, can also randomly arrange.Pass through convex design, E type magnetic ferrite magnetic core blank after sintering, gap is there is between two E type soft ferrite magnetic core products, adopt hemispheric profile design simultaneously, make the contact-making surface of the base end face of the pillar end face of lower floor E type magnetic ferrite magnetic core and upper strata E type magnetic ferrite magnetic core little as much as possible, it is made to be easy to be separated levels E type soft ferrite magnetic core products, and add fixture can be adopted man-hour first to be polished by the base end face of E type magnetic ferrite magnetic core at mill, again the pillar end face of the E type magnetic ferrite magnetic core having salient point is polished, rear road mill manufacturing procedure is not had an impact, such design reaches does not increase cost and the object not affecting performance.
As preferably, between described adjacent two projections, be spaced apart 2-4mm.By the design of spacing distance, reduce protruding quantity as much as possible, be convenient to mill processing.
As preferably, the diameter of described projection is 0.4-0.6mm.By the design of diameter, reduce protruding size as much as possible, be convenient to mill processing.
As preferably, the material of described projection is consistent with the material of this E type magnetic ferrite magnetic core.Such design can not affect the performance of E type magnetic ferrite magnetic core.
The beneficial effects of the utility model are: projection can recycling, does not increase production cost, does not affect performance, be applicable to the E type soft ferrite magnetic core products that overall length dimension is greater than 20mm, and structure is simple, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. base, 2. pillar, 3. protruding.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
In embodiment as described in Figure 1, a kind of E type magnetic ferrite magnetic core, comprise base 1 and three pillars 2, three pillars 2 are evenly arranged on base 1, the shape of its cross section is E type, pillar 2 and base 1 are integrated, and the end face of three pillars 2 is provided with some protruding 3, and the shape of protruding 3 is hemisphere.Wherein: be spaced apart 2-4mm between adjacent two projections 3, the diameter of protruding 3 is 0.4-0.6mm, and the material of protruding 3 is consistent with the material of this E type magnetic ferrite magnetic core.Protruding 3 can be regularly arranged, can also randomly arrange.
By protruding 3 designs, E type magnetic ferrite magnetic core blank after sintering, gap is there is between two E type soft ferrite magnetic core products, adopt hemispheric profile design simultaneously, make the contact-making surface of base 1 bottom surface of pillar 2 end face of lower floor E type magnetic ferrite magnetic core and upper strata E type magnetic ferrite magnetic core little as much as possible, it is made to be easy to be separated levels E type soft ferrite magnetic core products, and add fixture can be adopted man-hour first to be polished base 1 bottom surface of E type magnetic ferrite magnetic core at mill, again pillar 2 end face of the E type magnetic ferrite magnetic core having protruding 3 is polished, rear road mill manufacturing procedure is not had an impact.
