[0002] In the fields of household appliances, rail transit, new energy power generation, etc., traditional ferrite materials can no longer meet the requirements, and nanocrystalline magnetic rings are increasingly used.

[0003] The production process of a nanocrystalline magnetic ring made of a common iron-based nanocrystalline soft magnetic alloy usually involves first mixing elements such as iron, silicon, boron, copper, and niobium in a fixed ratio, heating them to 1400 degrees Celsius, then rapidly cooling to produce a strip-shaped substrate, winding the strip into a circular magnetic ring, and finally performing heat treatment to make it recrystallize again, thus obtaining a magnetic ring with good soft magnetic properties.

[0004] However, in some special occasions, special-shaped magnetic rings are required. However, the circular magnetic rings wound from strip materials can only be simply pressed into magnetic rings with regular outer shapes, such as racetrack-shaped magnetic rings and rectangular magnetic rings, and cannot be simply pressed into some magnetic rings with irregular outer shapes, such as D-shaped and arc-shaped slot-shaped.
