【発明の詳細な説明】 ［発明の目的］ （産業上の利用分野）。[Detailed description of the invention] [Purpose of the invention] (Industrial application field).
本発明は非晶質磁性金属薄帯を巻回してなる非晶質金属
磁心の製造方法に関する。The present invention relates to a method for manufacturing an amorphous metal magnetic core formed by winding an amorphous magnetic metal ribbon.
（従来の技術）
近年、トランス用磁心や磁気増幅器用磁心を構成する材
自として、その極めて優れた磁気特性から非晶質磁性金
属薄帯が注目されている。(Prior Art) In recent years, amorphous magnetic metal ribbons have attracted attention as a material for constructing magnetic cores for transformers and magnetic amplifiers due to their extremely excellent magnetic properties.
このような非晶質磁性金属を用いた磁心は、例えば非晶

。A magnetic core using such an amorphous magnetic metal can be produced by, for example, winding an amorphous magnetic metal ribbon into a predetermined shape on a winding jig, then cutting the amorphous magnetic metal ribbon and cutting the ends of the amorphous magnetic metal ribbon. After fixing the amorphous magnetic metal ribbon, it is manufactured by heat-treating the amorphous magnetic metal ribbon at a temperature below its crystallization temperature in order to remove strain and improve its magnetic properties.
（発明が解決しようとする問題点）
ところで、非晶質磁性金属薄帯は、ばね性の非常に大き

定化される。(Problem to be Solved by the Invention) By the way, amorphous magnetic metal ribbon is a material with extremely high spring properties, and it returns to its original shape if it is simply wound at normal room temperature. After winding it, cut it,
The cut end must be fixed with a jig, heat-resistant tape, etc., and the shape is fixed by subsequent heat treatment.

ては、熱処理前に形状くずれを生じる可能性もある。In this way, in the conventional manufacturing method, a step of fixing the cut end after winding and a heat treatment step are required, and fixing of the cut end is done by restoring the amorphous magnetic gold R ribbon. Since the force is large, workability is poor, and furthermore, depending on the fixing method, there is a possibility that the shape may be distorted before heat treatment.

性が悪くなる。Furthermore, in recent years, switching power supplies, for example, have become increasingly high-frequency in response to the demand for smaller power supplies, and as a result, the magnetic cores used are also required to be considerably smaller, and as they become smaller, they become even more compact. The restoring force of the crystalline magnetic metal ribbon increases, and the workability of fixing the cut end becomes even worse.
本発明はこのような従来の事情に対処してなされたもの
で、工程を簡略化し、作業性を向上させた非晶質金属磁
心の製造方法を提供することを目的とする。The present invention has been made in response to such conventional circumstances, and an object of the present invention is to provide a method for manufacturing an amorphous metal magnetic core that simplifies the process and improves workability.
