Abstract
The invention provides a method for removing a partial stress of an amorphous alloy iron core, which is characterized in that a hammer with a soft hammerhead is used to beat the amorphous alloy iron core which is processed through quenching. The beating refers to beating the upper end surface and the lower end surface, the surrounding side surfaces and the corners of the amorphous alloy iron core. The method for removing a partial stress of an amorphous alloy iron core has the advantages of effectively removing the magnetic performance of the amorphous alloy iron core through using the mode of manual beating, thereby improving the market competition of the amorphous iron core.
Description
Technical field
The present invention relates to a kind of method of eliminating amorphous alloy iron core localized stress, be used for the manufacturing process of amorphous alloy iron core, belong to the method and technology field of eliminating amorphous alloy iron core localized stress.
Background technology
Amorphous alloy is as energy saving and environment friendly " green material ", and the traditional silicon steel used with making the substation transformer iron core compared, and has significant low core loss property and is used widely.But in the chilling preparation process of amorphous band, and band cutting, curl, very easily produce stress in the processing, transportation, thereby influence the magnetic property of amorphous iron core.At present generally eliminate iron core stress by carry out anneal according to specific technology under magnetic field, this has played effect to a certain extent, but still has certain local stress in the iron core, thereby influences the performance of iron core, is necessary to be for further processing.
Summary of the invention
The purpose of this invention is to provide the local stress that a kind of iron core that can remove after the anneal exists, obviously improve the method for the performance of amorphous alloy iron core.
In order to achieve the above object, technical scheme of the present invention has provided a kind of method of eliminating amorphous alloy iron core localized stress, it is characterized in that, knocks amorphous alloy iron core after the anneal with the hammer of soft tup.
Can make each layer lamination of amorphous alloy iron core produce mechanical vibration and displacement by the mode of manually knocking, the mutual deformity effect that is subjected between each layer is eliminated, thereby obviously improve the magnetic property of amorphous alloy iron core.
Advantage of the present invention is: by utilizing the mode of manually knocking, effectively remove the magnetic property of amorphous alloy iron core, thereby improve the market competitiveness of amorphous iron core.
Embodiment
Specify the present invention below in conjunction with embodiment.
Embodiment
Step 1, earlier amorphous band is cut according to program after, utilize mould and related tool carry out stacked, crooked, support and technology such as stretch, push, tie up and make amorphous alloy iron core;
Heat-treating methods carries out the core annealing processing under step 2, the employing magnetic field; After finishing this step, there is 85～95% stress to be eliminated approximately, can not eliminate because the mechanism that produces is different but still have part stress;
Step 3, knock amorphous alloy iron core after the anneal with the hammer with rubber hammer head; The mechanical vibration of knocking the back generation make each interlayer of lamination take place effectively to move, thereby reach the purpose that discharges stress.
Manually knock and generally will act on the upper and lower end face of amorphous iron core, side and corner all around.Knocking of upper and lower end face is firmly moderate, in order to avoid owing to the vertical effect to lamination damages, falls slag.To around the iron core lateral knock should be vertically and side surface direction carry out, firmly can be big slightly, to cause that the effective displacement between lamination is a criterion.When the side is manually knocked, should about, front and back symmetries firmly, to guarantee that core configuration does not deform.The rubber hammer that manually knocks usefulness should be two, thereby makes the stressed symmetry of iron core, guarantees the physical dimension of iron core.
The instrument that manually knocks can be the instrument similar with rubber hammer, guarantee iron core avoid the damage and the distortion.
