Amorphous magnetic core surface coating process

Abstract

The invention relates to the technical field of amorphous magnetic cores, in particular to an amorphous magnetic core surface coating process, which is made of an amorphous-state magnetic core composite insulating material. The amorphous magnetic core surface coating process comprises the following steps of: (1) setting the temperature of a baking box until the temperature is proper; (2) treating residual pieces on the surfaces of the iron cores; (3) tidily placing the iron cores on iron discs; (4) placing the iron cores into the baking box according to the discs in layers for preheating; (5) taking the preheated iron cores out and uniformly spraying a powdery or liquid-state insulating material to the iron cores by using a lance; (6) placing the iron cores in the baking box to bake and pre-cure after one-time coating; and (7) reversely placing the iron cores on the iron discs after one-time baking, and repeating the action until the surfaces of magnetic cores are fully coated to obtain products. The amorphous magnetic core surface coating process has the advantages of simple process, uniform spray coating of insulating layers on the surfaces of the iron cores, consistent product thickness, small shape, close soluble adhesion of the insulating material, excellent hardness, smooth product surface, good linearity, low probability of scratching the insulating skin of an enameled wire during winding of the enameled wire and capability of guaranteeing the product quality.

Description

technical field [0001] The invention relates to the technical field of amorphous magnetic cores, in particular to a manufacturing process for making amorphous magnetic cores using composite insulating materials for amorphous magnetic iron cores. Background technique [0002] With the development of electronic technology, the requirements for electronic components are getting higher and higher. Amorphous magnetic cores are made of composite insulating materials with amorphous magnetic cores. Because of their excellent resistance to DC bias and small size, they have also Gradually, it was put into the production of inductive devices. However, there are box-packed and surface-cured types for the production and molding of the existing amorphous magnetic cores, but the box-packed type has a large volume, while the surface-cured type can effectively reduce the size, but the production work is inconvenient, the efficiency is low, the cost is high, and the surface is rough. , The t...
