Method for separating adhered magnetic cores

Abstract

The invention provides a method for separating adhered magnetic cores, comprising the following steps of: adding a certain amount of water which can spread across the adhered magnetic cores in a heating container and then heating to be boiling; putting 3kg to 5kg of adhered magnetic cores into the water for hot boiling for 1 to 3 minutes, and stirring during the hot boiling, then automatically separating part of adhered magnetic cores; and taking out the unseparated magnetic cores from the boiling water and softly and manually kneading until the adhered magnetic cores are separated. The method utilizes the principle of expanding with heat and contracting with cold to separate the adhered magnetic cores, has simple technology and simple and convenient operation, avoids mechanical collision during mechanical cutting, causes no damage to the products, and has extremely low damage rate to the magnetic cores, simultaneously, 3kg to5kg of the magnetic cores are separated in 1 to 3 minutes; therefore, relative mechanical cutting efficiency is greatly improved.

[0002] The ferrite core is sintered by stacking and sintering products. The stacking height of the products is generally 10-15cm. The sintering temperature of the products is usually 1400±20°C. Under high temperature sintering, the products will undergo a solid-phase chemical reaction to form ferrite. Due to the close contact of products, chemical reactions will inevitably occur, which will cause the adhesion of adjacent products. In order to avoid excessive adhesion, a small amount of alumina powder or clinker ferrite particles will be sprinkled between the adjacent upper and lower products before sintering , more withdrawal of alumina powder or clinker ferrite particles can effectively reduce the strength of magnetic core adhesion, but sprinkling more alumina powder or clinker ferrite particles will cause the main performance index of the product to decrease inductance and affect the product. At the same time, excessive use of alumina powder or clinker ferrite particles will also affect the appearance quality, such as defects such as yellowing of the appearance of the magnetic core or pitting on the surface, so it is not appropriate to use too much alumina powder or clinker For ferrite particles, only a small amount of alumina powder or clinker ferrite particles can be used, which will only reduce the strength of magnetic core adhesion, and the product will also have different degrees of adhesion

At present, the method of dividing the adhesive products into individual products is mainly to cut manually with a thin blade or a small guillotine or with a mechanical cutting machine. The disadvantages of these methods are: 1. Poor safety and easy to hurt hands; 2. Generally low efficiency; 3. The product damage rate is high, and the product will inevitably be cut during the mechanical cutting process, causing the product to fall off, so that it cannot be used
