Abstract
The invention provides a method for separating an adhered magnetic core, which is characterized in that a certain amount of water capable of overflowing the adhered magnetic core is added into a heating container and heated to boil; 3 kg-5 kg of the adhered magnetic cores are put into water for hot boiling for 1 min-3 min, the adhered magnetic cores are stirred while hot boiling, at the moment, the magnetic cores which are partially adhered can be automatically separated, and for the magnetic cores which are not separated, the magnetic cores which are not separated are taken out from the boiling water and the adhered magnetic cores are gently kneaded manually until the adhered magnetic cores are separated. The invention utilizes the principle of expansion with heat and contraction with cold to segment the adhered magnetic cores, has simple process and simple and convenient operation, avoids mechanical collision during mechanical cutting, does not damage products, has extremely low damage rate of the magnetic cores, and greatly improves the efficiency relative to mechanical cutting when 3 kg-5 kg of the magnetic cores are used for 1-3 minutes.
Description
Technical field
The present invention relates to a kind of method that the magnetic core that is sticked together is separated that is used for.
Background technology
The ferrite core sintering processing is that product stacks sintering; product stacks and highly is generally 10-15cm; the product sintering temperature is usually at 1400 ± 20 ℃; solid state reaction generation ferrite can take place in product under high temperature sintering; adjacent product is because chemical reaction inevitably also can take place in tight contact; thereby cause the adhesion phenomenon of adjacent product; for avoiding excessive adhesion; before sintering, can spill a small amount of alchlor powder or grog ferrite particle between the adjacent up and down product; remove an alchlor powder or grog ferrite particle more; can effectively reduce the intensity of magnetic core adhesion; but spill the decline that alchlor powder or grog ferrite particle can cause product main performance index inductance more; influence the properties of product quality; alchlor powder or grog ferrite particle use simultaneously is excessive; also can influence presentation quality; as jaundice of magnetic core outward appearance or surface defectives such as pit are arranged; therefore unsuitable too much use alchlor powder or grog ferrite particle; can only use alchlor powder or grog ferrite particle on a small quantity; so only can reduce the intensity of magnetic core adhesion, also can there be adhesion in various degree in product.At present the adhesion product being divided into the way of single product, mainly is manually to cut with thin blade or small-sized chopper or with mechanical cutter, and these method shortcomings are: 1, poor stability, easily hinder hand; 2, efficient is generally lower; 3, damage of product rate height, the inevitable cut wound product of meeting causes product to fall piece, so that can't use in the machine cuts process.
Summary of the invention
The present invention is directed to the deficiency that existing adhered magnetic cores cutting techniques exists, the method that adhered magnetic cores is cut apart that provides that a kind of technology is simple, easy and simple to handle, production efficiency is high, the product breakage rate is low
The method that adhered magnetic cores is cut apart of the present invention is:
In heating container, add a certain amount of water that can cover adhered magnetic cores, be heated to boiling; The magnetic core of 3kg-5kg adhesion is put into water to carry out heat and boiled 1 minute-3 minutes, magnetic core to adhesion when heat is boiled stirs, the magnetic core of part adhesion at this moment can be separated voluntarily, for the magnetic core that does not separate, from boiling water, take out, by manually the magnetic core of adhesion being rubbed gently, separate until the magnetic core of adhesion.
The principle that utilization of the present invention is expanded with heat and contract with cold is cut apart the magnetic core of adhesion, and technology is simple, easy and simple to handle, the mechanical collision when having avoided machine cuts, product is not caused damage, the magnetic core breakage rate is extremely low, and simultaneously 1-3 minute 3kg-5kg magnetic core time spent, machine cuts efficient greatly improves relatively.
Embodiment
According to technical scheme of the present invention, in temperature automatically controlled deep frying pan, add the water yield that can cover the 3kg-5kg adhered magnetic cores, the overall dimension of deep frying pan (length * wide * height) is: 1035 * 480 * 800mm, power: 7.5kW, voltage: 380v.Heat, seethe with excitement until water.The magnetic core of 3kg-5kg adhesion is put into the stainless steel sift basket, and stainless steel sift basket overall dimension (length * wide * height) is: 450 * 30 * 10mm, sieve aperture are Φ 4mm, and the sieve aperture distance is 4mm.To the sieve basket of magnetic core be housed, put into deep frying pan boiling water heat and boil, the water surface just soaked magnetic core.Product is when heat is boiled, the rod that has rubber sleeve with an end, that does not stop boils magnetic core to heat and stirs, according to the size of shape of product, magnetic core heat was boiled 1 minute-3 minutes, will sieve basket and mention from boiling water, filter the water in the dry screen basket fast, manually put on rubber gloves, the magnetic core of adhesion is rubbed gently, the magnetic core of adhesion can be cut apart voluntarily.This method is applicable to various middle-size and small-size magnetic cores, as UF shape, E shape, annular,, product is not caused damage, the product breakage rate is low, whole process safety coefficient height.
Claims (1)
1. method that adhered magnetic cores is cut apart, its feature is: add a certain amount of water that can cover adhered magnetic cores in heating container, be heated to boiling; The magnetic core of 3kg-5kg adhesion is put into water to carry out heat and boiled 1 minute-3 minutes, magnetic core to adhesion when heat is boiled stirs, the magnetic core of part adhesion at this moment can be separated voluntarily, for the magnetic core that does not separate, from boiling water, take out, by manually the magnetic core of adhesion being rubbed gently, separate until the magnetic core of adhesion.
