Process for producing magnetic ring

Abstract

The invention discloses a process for procuring a magnetic ring. The production process comprises the following operation steps: 1) pressing into a blank; 2) full-automatically chamfering the blank; and 3) sintering and moulding the blank, wherein the step 2) of full-automatically chamfering the blank is the process of chamfering the magnetic ring blank by using the full-automatic chamfering separator. The process for procuring the magnetic ring has the beneficial effects of simple technical route, few apparatus investment, and full-automatic chamfering process; the working efficiency can be effectively improved, the labour is saved, and the cost is reduced; the chips and dust are recycled, and the production process is green and environment-friendly, can reduce the hydroelectric energy consumption and save the cost and has excellent application foreground.

Description

technical field [0001] The invention relates to the field of magnetic ring production, in particular to a new process for producing magnetic rings. Background technique [0002] The magnetic core refers to a kind of ceramic magnetic metal oxide made of iron oxide, manganese oxide, nickel oxide and other oxide mixtures sintered at high temperature. Because the inside and outside of the magnetic ring need to be wound with enameled wire to make an inductor or transformer, and the magnetic ring will form burrs around the periphery during the pressing and forming process, and the burrs will damage the insulation layer of the enameled wire during winding and cause a short circuit in the inductor or transformer, so the magnetic ring The periphery needs to be rounded, that is, chamfered. [0003] The traditional magnetic ring production process generally includes the following procedures: powder pressing, pre-firing, chamfering, cleaning, drying, separation, and re-sintering. Vari...

Problems solved by technology

This process consumes a lot of electric energy, water energy, manpower, and takes a long time, about 2 days, and requires a lot of equipment investment, which requires the participation of high-power high-temperature sintering furnace, high-power rotary chamfering machine, dryer and other equipment

[0004] In the traditional process, the debris and powder produced after chamfering are washed away by the water, so part of the raw materials are wasted, and the raw materials are lost to nature, polluting the environment, and are not easy to recycle and separate

[0005] In addition, the time, energy consumption and labor cost occupied by the chamfering process in the traditional process are very high
