Problems solved by technology

However, in the prior art, because the insulating paint applied by the magnetic ferroalloy material cannot withstand high temperature, the metal lattice texture cannot be effectively restored, that is, its reduction performance cannot reach the best state; and the current production volume The process of winding the iron core is complicated, there are many hidden dangers in quality, and it is easy to cause a large number of defective products, and the production process requires a lot of manpower. At the same time, the price of silicon-containing materials is expensive, which greatly increases the production cost.

Abstract

The invention discloses a method for preparing a winding iron core. The iron core comprises a ribbon-shaped non-oriented magnetic material. The method comprises the following steps of: (1) preparing mixed insulating paint; (2) loading the material; (3) feeding the material; (4) setting the parameters; (5) and producing. The method has the advantages of fewer working steps and simple preparation, greatly reduces the production cost, ensures the precision and consistency of the products and greatly enhances the interlaminar insulation property, high temperature resistance, magnetic conducting effect and percent of pass of the iron core. The method adopts a constant pressure gas and high oil pressure mode, combines the non-oriented magnetic material which is uniformly rolled and wound by 360degrees and meanwhile matches to coat the mixed insulating paint on the surface of the non-oriented magnetic material to fully fill the tiny gap generated by material deformation and permeate into the interior of the material, thereby wholly enhancing the performance of the product. The iron core of the invention has the advantages of reasonable structure, high temperature resistance, high interlaminar insulation property and higher magnetic conducting effect.

Description

technical field [0001] The invention relates to an iron core processing technology, in particular to a method for preparing a wound iron core and an iron core made by implementing the method. Background technique [0002] In the prior art, there are mainly two manufacturing methods for iron cores used in electrical appliances such as ballasts: lamination and winding. [0003] The laminated iron core is made of non-oriented magnetic materials stacked in a certain shape. Because the non-oriented magnetic material sheets are not compact enough, there is an air gap in the magnetic circuit, and the high magnetic permeability direction of the local material is in line with the The direction of the magnetic circuit is inconsistent, so that the performance of the iron core is poor, and the electrical appliances made have high no-load loss and high noise. [0004] In order to overcome the defects of the above-mentioned laminated cores, wound cores are usually used; in order to furth...
