Problems solved by technology

[0002] At present, in the production of magnetic rings, in order to improve product performance and output, ring magnetic cores are usually used and then sintered. During the molding process, the magnetic rings are prone to burrs. The traditional process is to polish the products after sintering. After the sintering of the magnetic ring is completed, the burr density is high, and it needs a long time of strong vibration to remove it, so that the product performance drops greatly and the electrical performance qualification rate is low.

Embodiment 1

[0012] Embodiment 1 of the magnetic ring production process of the present invention comprises the following steps successively:

[0013] a) First, the raw materials of the magnetic ring are distributed according to the group, and the green body of the magnetic ring is made;

[0014] b) Then perform a false firing on the green body of the magnetic ring, and the temperature range of the false firing is 750-900°C;

[0015] c) then put the fake-fired magnetic ring green body into the grinding fixture, and put it on the grinding machine for polishing;

[0016] d) Finally, the green body of the magnetic ring is finally sintered.

[0017] The so-called false firing means that the magnetic ring is placed in surface heat treatment equipment for high temperature treatment, such as in a rotary kiln, and the temperature generally does not exceed 1000 °C. The temperature of the false firing in the b) step is 850°C, which can decompose the organic components in the magnetic ring and incr...

Abstract

The invention discloses a magnetic ring production technology. The magnetic ring production technology sequentially includes the following steps that (a) raw materials of magnetic rings are proportioned well according to components, and magnetic ring green bodies are made; (b) false burning is performed on the magnetic ring green bodies one time, and the temperature range of false burning is 750-900 DEG C; (c) the magnetic ring green bodies which undergo false burning are placed into grinding clamps and then placed on a grinding machine to be polished; (d) at last, final sintering is performed on the magnetic ring green bodies. Compared with a traditional production process, according to the magnetic ring production technology, burrs of the magnetic rings are removed, peak power utilization can be avoided, the production cost is lowered to a certain extend, the electrical performance qualification rate of the magnetic rings is improved, the final sintering time is shortened, original production processes are optimized and improved, the technology is simple, and operation is easy.

Description

technical field [0001] The invention relates to the field of magnetic ring processing, in particular to a magnetic ring production process. Background technique [0002] At present, in the production of magnetic rings, in order to improve product performance and output, ring magnetic cores are usually used and then sintered. During the molding process, the magnetic rings are prone to burrs. The traditional process is to polish the products after sintering. After the sintering of the magnetic ring is completed, the burr density is high, and it needs a long time of strong vibration to remove it, so that the product performance drops greatly and the electrical performance qualification rate is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a magnetic ring production process, and the magnetic ring produced by the production process has a high qualified rate of electrical properties. [0004] In order to achiev...
