Description

Amorphous or nanocrystalline magnetic core rapid shaping annealing fixture

Technical Field

The utility model belongs to the technical field of the magnetic core shaping, concretely relates to quick design annealing frock clamp of amorphous or nanocrystalline magnetic core.

Background

In recent years, along with the rapid development of high frequency, small-sized and integrated power electronic technology, various electromagnetic interference (EMI) and electromagnetic compatibility (EMC) problems are also brought, and power conversion and EMC devices serving as the most core foundation are required to have higher-performance magnetic materials to support the design requirements.

Amorphous or nanocrystalline soft magnetic materials are characterized by excellent properties such as high resistivity, high saturation induction, high permeability, high curie temperature, low loss, etc. which are not possessed by conventional magnetic materials, and magnetic element products processed by the amorphous or nanocrystalline soft magnetic materials are paid great attention by power supply design engineers.

However, the magnetic elements have different structures, which results in different shapes of the cores therein. Generally, an amorphous or nanocrystalline magnetic core needs to be processed and formed through a certain auxiliary shaping jig. If the customized jig is too complicated in structural design, the processing cost of the customized jig can be high, the production operation difficulty of the customized jig in the shaping process can be increased, and the mass production efficiency is seriously influenced.

Several magnetic cores are placed on the same flat plate in parallel or orthogonally, and the shape of the magnetic core is extruded to have a desired shape by pushing the screws of the left and right side plates and the front and rear side plates. Because the appearance structure problem of magnetic core has only been solved to this frock, the magnetic core quantity of single frock design is limited, need constantly twist many screws in the process and promote the curb plate displacement, and actual operation is comparatively complicated, and production efficiency is low, is not suitable for mass production operation, and the processing cost of this frock is also higher moreover.
