Problems solved by technology

Since the thin strip gap of the iron-based amorphous / nanocrystalline alloy core is very small, usually only a few microns, the polymer resin glue is not easy to fill.
If it is not fully filled, it is possible to generate amorphous / nanocrystalline alloy chips when cutting

Abstract

The invention discloses a manufacturing process of a high-filling easy-to-cut iron-based amorphous nanocrystalline alloy iron core. The manufacturing process is characterized by comprising the following steps of S1 obtaining an annular iron core through conventional processes such as smelting, amorphous thin strip spraying, winding, vacuum annealing and the like; S2 putting the iron core in the step S1 into a working chamber which is a cylindrical container with the size slightly larger than that of the iron core, adding a macromolecule resin adhesive, and immersing the iron core; S3 putting the working chamber together with the iron core and the macromolecule resin adhesive into a high-speed centrifugal throwing cylinder of a supergravity machine, setting the supergravity acceleration tobe 800 to 3000g, and then performing high-speed rotation for 3 to 10 min; S4 taking out the working chamber, pouring out the residual macromolecule resin adhesive, and taking out the iron core; and S5placing the iron core on a flat workbench for 24 to 48h at the room temperature to obtain the needed iron core . Compared with the prior art, the manufacturing process has the advantages that supergravity impregnation is adopted for replacing vacuum impregnation, and thin strip gaps of the iron-based amorphous nanocrystalline alloy iron core can be better filled with the macromolecule resin adhesive.

Description

technical field [0001] The invention relates to the field of iron core processing, in particular to a manufacturing process of a highly filled and easy-to-cut iron-based amorphous nanocrystalline alloy iron core. Background technique [0002] Iron-based amorphous / nanocrystalline alloy cores have high magnetic permeability and low core loss, and have been widely used in high-precision transformers and high-frequency power supplies. The manufacturing process of iron-based amorphous / nanocrystalline alloy iron core usually includes smelting to obtain master alloy, spinning strip to obtain amorphous alloy thin strip, winding forming, and vacuum annealing to realize the transformation of amorphous alloy into amorphous / nanocrystalline alloy. Usually, the iron-based amorphous / nanocrystalline alloy core is in the shape of a body of revolution, such as circular ring, elliptical ring, rectangle and racetrack. The shape of the rotor is relatively troublesome when winding multi-turn coi...
