Abstract
The invention discloses an amorphous alloy plane stepped iron core, which comprises a template, small iron cores, a big iron core and an internal template mould. The template is divided into an external template and an internal template. The big iron core is located on the inner side of the external template, two small iron cores are arranged in parallel in the big iron core, the internal template is disposed in the middle of each small iron core, the internal template mould is installed in the internal template, and the external template enables the entire core to be bound and formed through binding steel belts. On the design conditions of equal iron core magnetic density, turns per coil and specifications for using wires, materials of circular coils winding round the amorphous alloy plane stepped iron core only account for 91% of square coils winding amorphous alloy single-belt-material iron cores, and materials are effectively saved. In addition, the amorphous alloy plane stepped iron core adopts a closed structure, lap joint ports are not provided, generated magnetizing current is small, generated noise is small, and the amorphous alloy plane stepped iron core is beneficial for creating good work and life environment.
Description
Technical field
The present invention relates to the manufacturing technology field of amorphous alloy iron core, a kind of specifically non-crystaline amorphous metal plane staged is unshakable in one's determination and preparation method thereof.
Background technology
Amorphous alloy distribution transformer is a kind of energy-saving controller switching equipment that adopts new material, new construction, new technology, and its core material is a kind of non-crystaline amorphous metal, compares with the traditional silicon iron and steel heart, has outstanding low no-load loss characteristic.Existing amorphous alloy transformer core is by the folded system back extrusion modling of some groups of amorphous alloy strips; For guaranteeing that amorphous alloy strips in the amorphous alloy transformer core can be not loose and break away from; Amorphous alloy transformer core adopts 0.3 millimeter silicon steel sheet parcel usually inside and outside iron core, adopt coating adhesive on the end face of lap seam of amorphous alloy strips or epoxy resin is cured, seals and insulate and have on the iron core.Said structure is the single band core construction of non-crystaline amorphous metal, and so-called single band iron core exactly can only be with a kind of iron core of doing in 142mm or 170mm or three kinds of bands of 213mm, and it also can be two-layer; Equal 2*142mm or 2*170mm or 2*213mm; Make that like this coil is a square structure, square coil is many with material, and the strength of sudden short circuit does not have being evenly distributed on circular coil in the distribution of square coil on the other hand; Be that anti-short circuit capability is relatively poor; Single in addition band bottom unshakable in one's determination all is provided with the overlap joint mouth, and the exciting curent and the noise of generation are bigger, bring pollution to surrounding environment.
Summary of the invention
In order to solve the deficiency of prior art; The present invention provides a kind of non-crystaline amorphous metal plane staged unshakable in one's determination; Adopt circular coil and staged band winding mold structure, it is had under, coil turn close at equal magnetic unshakable in one's determination, the design condition with the wire gauge lattice, with the effectively minimizing unshakable in one's determination of the single band of the more existing non-crystaline amorphous metal of material; Can reduce cost of manufacture unshakable in one's determination, reach simultaneously and improve the amorphous alloy core product percent of pass and reduce anti noise.
In order to solve the problems of the technologies described above; Technical scheme of the present invention is: a kind of non-crystaline amorphous metal plane staged is unshakable in one's determination, comprises template, little iron core, big unshakable in one's determination, internal mold mold, and it is characterized in that: said template is divided into exterior sheathing and inner formword; Big iron core is positioned at the exterior sheathing inboard; Be arranged with two little iron cores side by side in the big iron core, be provided with inner formword in the middle of each little iron core, the internal mold mold is installed in the inner formword.
Described exterior sheathing is through the whole big colligation moulding unshakable in one's determination of colligation steel band.
Another technical problem to be solved by this invention provides a kind of above-mentioned non-crystaline amorphous metal plane staged manufacture method unshakable in one's determination.
In order to solve the problems of the technologies described above, technology side of the present invention a case is: the manufacture method that a kind of non-crystaline amorphous metal plane staged is unshakable in one's determination may further comprise the steps:
The first step: rolling: become winding to be divided into 1 of 5 volume 5 amorphous and become winding;
Second step: itemize: step is obtained 1 becomes winding to become the little band of 6-10 specification with the gang tool itemize, and width is respectively 35mm-142mm and does not wait;
The 3rd step: winding mold: band is arrived the thickness of setting round inner formword and the coiling of internal mold mold successively by order from small to large is stepped; Its thickness is that 3.5-26.5mm does not wait, and forms a little iron core, the more same little iron core of coiling as stated above; These two little iron cores are fixed side by side; Band is arrived the thickness of setting successively by order from big to small round these two little coilings unshakable in one's determination, its thickness is that 26.5-3.5mm does not wait, and one of back coiled is big unshakable in one's determination;
The 4th step: annealing: with the method for exterior sheathing and steel band colligation with whole colligation moulding unshakable in one's determination; The internal mold mold is taken out; Whole iron core is put into the special-purpose annealing furnace of amorphous core, and two little central authorities unshakable in one's determination pass copper bar and add vertical magnetoelectricity stream, with proprietary annealing process annealing in process;
The 5th step: dipping lacquer: unshakable in one's determination whole that will move back fire immerses abundant dipping lacquer in the special epoxy resin lacquer, and slinging then drips off lacquer, puts into the baking oven baking again.
It is 142mm, 170mm, 213mm that described amorphous becomes the specification of winding.
The girth of said circular cross-section unshakable in one's determination is 4.72cm.
Described annealing process is at exciting current 750-1200A, and 335 ℃-350 ℃ are incubated 45-90 minute down, and cooling is afterwards also come out of the stove in the time of 250 ℃, and is air-cooled fast after coming out of the stove.
The temperature 110-130 degree of described baking, the time is 2-3 hour.
Beneficial effect of the present invention is: staged peripheral girth unshakable in one's determination in non-crystaline amorphous metal provided by the invention plane is respectively 4.72cm; And the single band core section of traditional non-crystaline amorphous metal girth is 5.18cm, and just equal magnetic unshakable in one's determination is close, under the coil turn, the design condition with the wire gauge lattice, around non-crystaline amorphous metal provided by the invention plane staged iron core around circular coil only account for around 91% of the single band of non-crystaline amorphous metal square coil unshakable in one's determination with material; Effectively save and use material; The staged structure of remaining silent that adopts unshakable in one's determination in non-crystaline amorphous metal plane overlaps mouth in addition, and the exciting curent of generation is little; The noise that produces is little, helps creating good operation, living environment.
