Description
Technical field
The utility model is related to a kind of magnetic core blank, more particularly to a kind of manganese-zinc ferrite magnetic of suitable center pillar air gap processing
Core blank.
Background technology
Manganese-zinc ferrite core has the advantages that thermal resistance is small, attenuation is small, power is big, working frequency is wide, and it is widely used in
Small volume and high-power transformer.The production process of manganese-zinc ferrite core is by particulate material preparation, die mould, sintering, mill processing
Constituted with go-on-go five processes.Die mould is that particulate material is produced into magnetic core by the method for pressure forming using press by mould
Blank, then by blank, sintering reaction generates manganese-zinc ferrite core blank on nitrogen kiln.Mill processing is the knot in magnetic core blank
Conjunction face is ground, and obtains suitable inductance value.In order to prevent manganese-zinc ferrite core from magnetic saturation occur, it is necessary to be combined in magnetic core
Face opens up air gap, typically opens up air gap on magnetic core center pillar, has the advantages that inductance stabilization, leakage field is few, electromagnetic interference is small.Tradition
The general side pin of manganese-zinc ferrite core blank and center pillar it is contour, first carry out base processing, then the combination for carrying out side pin and center pillar
Face processes, and finally carries out center pillar air gap processing.
In order that existing EQX manganese-zinc ferrite cores inductance stabilization, prevents occurring magnetic saturation in transformer use, need
Will the air gap of post grinding wherein.The side pin of EQX magnetic core blanks surrounds center pillar in major arc, it is impossible to entered using accurate passing through type grinder
Row center pillar air gap is processed, because air gap can equally be left in the side pin of EQX magnetic core blanks, this is not fair in EQX magnetic cores
Perhaps, so EQX magnetic cores blank can only carry out center pillar air gap processing using vertical grinder.When being processed using vertical center pillar air gap
EQX magnetic cores blank can only grind one by one, it is impossible to the continuous rapid processing as being processed by formula center pillar air gap, and vertical
The speed of center pillar air gap processing will also be significantly less than is processed by formula center pillar air gap, especially when center pillar air gap depth is more than 1mm,
Vertical center pillar air gap processing efficiency can be lower.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of manganese of suitable center pillar air gap processing
Zn ferrite magnetic core blank, can greatly improve the production efficiency of magnetic core blank center pillar air gap processing.
To achieve the above object, the utility model provides following technical scheme：A kind of manganese of suitable center pillar air gap processing
Zn ferrite magnetic core blank, including base, the center pillar that cylinder is vertically installed with the base and the side pin for surrounding center pillar,
Gap with major arc shape between the corner and center pillar, the center pillar top is less than side pin top, in the base end face
Between position be provided with dumping groove in the width direction.
Further, the vertical range between center pillar top and side pin top is 2~5mm.
Further, the width of dumping groove is the 1/3~1/2 of middle column diameter, and dumping groove depth is 0.05~0.25mm.
The utility model has the advantage of：
1. magnetic core blank center pillar top only need to grind magnetic core blank side pin to given size less than side pin top, just can be complete
Into the processing of magnetic core blank center pillar air gap, reduce the grinding of conventional cores blank center pillar and open gap this procedure of processing, substantially increase magnetic
The production efficiency of core blank center pillar air gap processing；
2. magnetic core blank center pillar top is less than side pin top, and the space reserved when multi-laminate is burnt helps to sinter dumping,
Along with the dumping groove that magnetic core blank base is opened up, magnetic core blank center pillar cracking, improves magnetic core blank when preventing multi-laminate from burning
Sintering quality and yield.

Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines diagram and specific embodiment, and the utility model is expanded on further.
As shown in Figure 1-2, the utility model proposes a kind of suitable center pillar air gap processing manganese-zinc ferrite core blank,
Including base 3, be vertically installed with the base 3 cylinder center pillar 2 and surround center pillar 2 side pin 1, the corner 1 with
Gap with major arc shape between center pillar 2, the top of the center pillar 2 is less than the top of side pin 1, the centre position of the bottom surface of the base 3
Dumping groove 4 is provided with the width direction.
Further, the vertical range between the top of center pillar 2 and the top of side pin 1 is 2~5mm.
Further, the width of dumping groove 4 is the 1/3~1/2 of the diameter of center pillar 2, and the depth of dumping groove 4 is 0.05~0.25mm.
The utility model magnetic core blank center pillar top only need to grind magnetic core blank side pin to regulation chi less than side pin top
It is very little, the processing of magnetic core blank center pillar air gap just can be completed, reduce the grinding of conventional cores blank center pillar and open gap this procedure of processing, significantly
Improve the production efficiency of magnetic core blank center pillar air gap processing；Burnt in multi-laminate less than side pin top at magnetic core blank center pillar top
When the space that reserves help to sinter dumping, along with the dumping groove that magnetic core blank base is opened up, magnetic core when preventing multi-laminate from burning
Blank center pillar ftractures, and improves magnetic core blank sintering quality and yield.
Embodiment of above only to illustrate technology design of the present utility model and feature, its object is to allow the skill of this area
Art personnel understand content of the present utility model and are carried out, and can not limit protection domain of the present utility model, all with this
According to the equivalent change or modification that the utility model Spirit Essence is done, should all cover in protection domain of the present utility model.
