Description
Technical field
The present invention relates to the technical fields of magnetic core processing technology, more specifically, it relates to a kind of amorphous, nanocrystalline magnet core
Annealing fixture.
Background technique
Magnetic core is in annealing, if the not sizing of fixture, is easy to appear the phenomenon that becoming flat or variation ellipse.If magnetic core is moving back
Occur the situation of flat or ellipse when fiery, when magnetic core solidification, magnetic core need to be restored to circular, but meeting in this way
The sharp fall for leading to magnetic permeability influences the parameter of magnetic core, results even in magnetic core and scraps.Magnetic conductivity is caused to decline
The reason is that: because magnetic core, in furnace annealing, the magnetic conductivity of magnetic core is formed according to the shape of magnetic core, severely deformed magnetic core
Magnetic conductivity can lose one times or so.So amorphous or nanocrystalline magnetic core are in annealing, it is desirable that magnetic core in annealing furnace always
It is round, and can not occurs the situation of flat either ellipse when solidifying, just can guarantee magnetic conductivity in this way.
Currently, the shape in order to guarantee magnetic core, generallys use winding mould and carries out shaping to the periphery of magnetic core.But it is releasing
When magnetic core, magnetic core often plays packet；And in annealing, magnetic core is to shrink, there is no assurance that shape of the magnetic core in annealing
Shape is circular, causes defective products more, cannot guarantee the magnetic conductivity of magnetic core well.
Summary of the invention
The technical problem to be solved by the present invention is in view of the deficiencies of the prior art, provide a kind of amorphous, nanocrystalline magnet core moves back
Fiery fixture, it is round that magnetic core, which is effectively guaranteed, in annealing or solidification.
The technical scheme is that being: a kind of amorphous, nanocrystalline magnet core annealing fixture, including shaping loop, it is described fixed
Type circle is plugged in magnetic core, and the outer wall of the shaping loop and the inner wall of magnetic core are adapted.
It is improved further, the shaping loop, which is equipped with, is divided into shaping loop split type the first circle body and the second circle
The grooving of body, first circle body and the second circle body pass through fixed device connection.
Further, the side of first circle body is equipped with the first mounting groove, and the side of second circle body is equipped with second
Mounting groove, first mounting groove are connected with the second mounting groove, and one end of the fixed device is mounted in the first mounting groove,
The other end is mounted in second mounting groove.
Further, the fixed device includes at least one fixed link and locking assembly, the both ends of the fixed link

Specific embodiment
Below with reference to embodiment, the invention will be further described, but does not constitute any limitation of the invention, any
The modification for the limited times that people is made in scope of the invention as claimed, still in scope of the presently claimed invention.
- Fig. 2 refering to fig. 1, a kind of amorphous of the invention, nanocrystalline magnet core annealing fixture, including shaping loop 2.Shaping loop 2 is inserted
It connects in magnetic core 1, the outer wall of shaping loop 2 and the inner wall of magnetic core 1 are adapted.The shaping loop 2 being adapted by one with 1 inner ring of magnetic core
It is plugged in magnetic core 1, when magnetic core 1 is annealed, magnetic core 1 is finalized circle 2 during contraction and carries out shaping fixation, thus to magnetic
1 inner ring of core has carried out effective sizing, avoids the problem of making its deformation because of the contraction of magnetic core 1, and then ensure that magnetic core 1 is moving back
Fire or solidification when be it is round, greatly improve the qualification rate of product, while also improving the quality of product.
Preferably, it is equipped with gap 11 corresponding with the contraction size of magnetic core 1 between magnetic core 1 and shaping loop 2, is moved back for magnetic core
Allowance for shrinkage is provided when fiery, in order to which magnetic core 1 can smoothly be shunk.And magnetic core 1 annealing when, size is not
Together, the contraction size of magnetic core 1 is also different, as shown in the table:
It can be seen that the size of biggish magnetic core 1 and contraction size: its size is bigger, and it is also bigger to shrink size.Therefore, magnetic core
The size in the gap 11 between 1 and shaping loop 2 can be selected according to the magnetic core 1 of different size, to be suitable for different size
Magnetic core 1.
Preferably, buffer layer 10 is equipped in the gap 11 between magnetic core 1 and shaping loop 2, buffer layer 10 is wrapped in shaping loop 2
Outer wall.Specifically, the buffer layer 10 is buffering packing paper, it can be used for buffering, absorb the shrinkage stress of magnetic core 1, further to magnetic
Core 1 is protected.
