Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an amorphous nanocrystalline rectangular magnetic core mold. Background Art

[0002] Amorphous and nanocrystalline magnetic cores are wound from multiple layers of amorphous or nanocrystalline ribbon. Before the core is manufactured, a shaft is typically machined, then metal ribbon is wrapped around it. However, the shaft is typically machined from a single piece of metal, making it heavier and causing the core to heat up more slowly during heat treatment. Due to the softness of the metal ribbon, gaps form during the winding process, requiring the core to be assembled using a clamp or steel strapping. This clamping method results in larger core tolerances, impacting core quality.

[0003] However, the prior art still has some shortcomings. The shaft core in the prior art is made of a piece of metal. During heat treatment, the temperature of the magnetic core rises slowly. Since the shaft core is heavy, it is not convenient for staff to operate or maintain.

[0004] Therefore, we propose an amorphous nanocrystalline rectangular magnetic core mold to solve this problem. Utility Model Content
