There is strong demand, it is very wide in computer, mobile phone, automation equipment and electronic transformer etc. purposes.In iron
It is needed in ferrite core manufacturing process by processes such as powder processed, compacting, sintering.In traditional pressing process, since mold uses
It will produce gap after a period of time, suppress the magnetic core come and will produce burr, influence appearance, line copper-clad line can be scratched when serious,
Lead to the pressure resistance bad phenomenons such as bad.In the prior art, it commonly uses and manually magnetic core is polished.Artificial polishing manually uses hair
It brushes and the magnetic core surface spikes by compacting is wiped.The method of this magnetic core wiping needs to put into a large amount of manpowers, wiping effect
Rate is low.
Number of patent application is that the patent of invention of CN201510472693.9 discloses a kind of magnetic core burr remover, including magnetic
Core conveyer belt is conveyed by the magnetic core after press punch forming by magnetic core conveyer belt, it is characterised in that：On the magnetic core conveyer belt
Side is equipped with the hairbrush for deburring, and the bristle of the hairbrush is contacted with the magnetic core conveyed on magnetic core conveyer belt, the hairbrush peace
Loaded on fixing bracket, the fixing bracket is equipped with vibrating motor, and the vibrating motor is shaken by vibrating mechanism band electric brush
It is dynamic.The device deburring is efficient, and deburring effect substantially improves.
But above-mentioned apparatus is polished magnetic core using machinery, when magnetic core especially smaller to size is polished,
Magnetic core breakage rate is higher, and it is big to scrap ratio, and inductance consistency is very poor, is unable to reach the requirement of inductance parameters " CPK ".
Invention content
The present invention overcomes the deficiencies in the prior art, a kind of difference according to magnetic core size is provided and selects different polishing materials
The magnetic core polishing method for expecting, ensureing polishing effect and reducing magnetic core breakage rate solves and utilizes mechanical equipment pair in the prior art
Magnetic core breakage rate high problem when magnetic core is polished.
In order to solve the above technical problems, the present invention uses following technical scheme：
A method of different size of magnetic core is polished, is included the following steps：
(1) it determines a setting value for distinguishing big magnetic core and small magnetic core, measures and record the long length of side of polished magnetic core
Degree, by the length of magnetic core long side compared with setting value, determines magnetic core type；
(2) magnetic core is added in the roller of polishing machine；
(3) polishing material is added in roller, the polishing material when magnetic core is big magnetic core is diamond dust, when magnetic core is small
Polishing material when magnetic core is water；
(4) polishing time and frequency are adjusted, starts polishing machine and magnetic core is polished；
(5) magnetic core after polishing is cleaned up with diluent, then is dried magnetic core with oven.
As the preferred embodiment of the present invention, Buddha's warrior attendant sandbox and water tank, Buddha's warrior attendant sandbox and water tank are provided on the polishing machine
It is connected to the roller of polishing machine by pipeline, the pipeline connected on the pipeline and water tank connected on Buddha's warrior attendant sandbox is mounted on valve
Door；In step (3), Buddha's warrior attendant is added to the roller of polishing machine by the pipeline connected on Buddha's warrior attendant sandbox when magnetic core is big magnetic core
Sand, when magnetic core is that water is added to the roller of polishing machine by the pipeline connected on water tank in small magnetic core.
As the preferred embodiment of the present invention, after step (1), following steps are carried out：
(1a) foam beads is added in polished magnetic core, and the weight ratio of foam beads and magnetic core is 1：20~1:
10。
As the preferred embodiment of the present invention, after step (2), following steps are carried out：
(2a) starts exhaust fan, takes the foam beads for polishing machine cylinder away with exhaust fan, waits for that foam beads are all taken out
Exhaust fan is closed after walking.
As the preferred embodiment of the present invention, the drum inner surface of the polishing machine is equipped with spongy layer.
Compared with prior art, the beneficial effects of the invention are as follows：
1, the present invention by magnetic core according to the long side length of magnetic core to being divided into big magnetic core and small magnetic core, if magnetic core is big magnetic
Core uses diamond dust as polishing material when being polished to it；If magnetic core is small magnetic core, make when being polished to it
Use water as polishing material.In this way, while ensureing polishing effect, the breakage rate of magnetic core can be reduced.Conventional cores polishing is made
Industry is all made of solid material and makees polishing material no matter magnetic core size.That the invention avoids the magnetic core breakage rates of traditional approach is high,
The big problem of ratio is scrapped, inductance consistency is improved, product is made to reach the requirement of inductance parameters " CPK ".
