Description
Technical field
The present invention relates to a kind of soft magnetic alloy lamination element, especially a kind of soft magnetic alloy lamination element and manufacture method of forming by multilayer magnetically soft alloy thin slice and binding agent thereof.
Background technology
Magnetically soft alloy is widely used in electromagnetism transform fields such as transformer core, inductor iron core, yoke.When magnetically soft alloy was applied to yoke, it mainly acts on was the conducting magnetic circuit.If yoke is operated in the stationary magnetic field, can make with the bulk magnetically soft alloy; If be operated in the alternating magnetic field, then need to use the lamination of sheet magnetically soft alloy, to reduce the eddy current of yoke inside.
Since yoke in magnetic circuit, play the control magnetic flux flow to, increase local magnetic flux density, prevent or reduce multiple effect such as leakage field, in recent years, the fast development of industries such as electric power, electronics, electromechanics has proposed more and more stricter requirement to yoke with magnetically soft alloy.For example, the design work rotating speed of many specific type of electric machines is up to tens thousand of rev/mins, and the changes of magnetic field frequency of stator and internal rotor reaches hundreds of hertz-tens thousand of hertz.Again for example, in MR imaging apparatus, use a large amount of magnetically soft alloys as yoke up and down between two magnetic poles, and yoke is operated in stationary magnetic field and the formed stack of the high-frequency alternating magnetic field magnetic field, the eddy current of yoke is one of key factor that influences image quality.In addition, electric meter, relay, electron detector, charged particle deflection system etc. also need high-quality yoke.
The traditional soft magnetic alloy of making yoke is silicon steel sheet and permalloy sheet.At first these alloy rollings are become the thin slice below 1 millimeter, show coating then, again large amount of thin sheets is piled up, welding or bonding, cutting and form big block element.But under the high-frequency work environment of mentioning in the above, the ordinary silicon steel disc is limit owing to rolling thickness, and eddy current loss is big, high can not the continuation of iron loss used, and must adopt ultra-thin silicon strip.But, on the one hand its magnetic property and imperfection, cost is very high on the other hand, against in the developing direction that reduces device cost.Permalloy is because the initial permeability height, coercive force is little, resistivity is bigger, and its processing thickness can be less than 0.01mm, therefore become one of candidate's magnetically soft alloy of yoke manufacturing, but because high magnetic conductance permalloy counter stress is very responsive, shear or traditional yoke manufacturing process such as punching press can influence very greatly to magnetism of material, permalloy makes by its yoke of making and does not have the price competitive advantage because of containing the mass expensive metallic nickel in addition.
Non-crystaline amorphous metal is the magnetically soft alloy of new generation of 20th century the eighties realization industrialization.This material is because of possessing processing thickness (about 0.03mm) and high resistivity (about 130 μ Ω cm as thin as a wafer, be more than the twice of silicon steel sheet and permalloy) and have good high frequency characteristics, especially high permeability and low eddy current loss have been widely used in iron cores such as range transformer, instrument transformer at present.20th century late nineteen eighties, nanometer crystal alloy has appearred again in the way by the non-crystaline amorphous metal heating crystallization, it has comprehensive magnetic characteristic almost best in all magnetically soft alloys, is used widely rapidly in fields such as high frequency transformers.
In the prior art, the amorphous nano peritectic alloy generally all uses in the mode of Wound core.Though also be cured in some cases and cut, only require the magnetic characteristic of element usually, and special machinery and electromagnetic propertys such as intensity, toughness, layer insulation are not explicitly called for.But,,, the mechanical strength and the toughness of element is had specific (special) requirements because yoke need fix through assembly process mostly if the amorphous nano peritectic alloy is applied to yoke.In addition, if yoke is operated in the high frequency magnetic field, also require element to have good layer insulation characteristic, with further inhibition eddy current.
Chinese patent application 99815455,01806129,01810721 and 01811986 has disclosed the method for making motor stator and MR imaging apparatus yoke with Fe-based amorphous alloy.Wherein, the application No.99815455 described have laminated construction, key component is Fe
80Si
11B
9The amorphous bulk element, its manufacture method comprises operations such as amorphous thin ribbon cutting, stacked, annealing, epoxy resin cure, shearings.Application No.01806129 and 01810721 has further proposed the claim of the core loss of the non-crystal cell of the block lamination of FeSiB under characteristic frequency and magnetic field.Application No.01811986 then attempts making lamination non-crystaline amorphous metal rod with the new technology of punching press, and drift and die tool adopt the carbide material of high rigidity during enforcement, has reduced the degree of wear of stamped workpieces well.
Yet,, unavoidably can cause the wearing and tearing of cutter and mould when shearing or punching because non-crystaline amorphous metal has high shear strength.Simultaneously, use common epoxy resin cure element after because the fragility of epoxy resin is bigger, cause whole element toughness deficiency, easily cracking even broken in cutting, assembling and use.Common in addition epoxy resin paint-dipping process can not effectively guarantee epoxy resin even coating between each lamella in element, can make element inner heat in alternating magnetic field thus, produces eddy current loss.
