Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core production and manufacturing, in particular to a residual magnetism removal device for grinding magnetic cores. Background Art

[0002] A magnetic core is a sintered magnetic metal oxide composed of a mixture of various iron oxides. Magnetic cores are formed by pressing iron powder into a mold and then sintering in a nitrogen-protected high-temperature sintering furnace. They are used in coils and transformers in various electronic devices. The production process of magnetic cores primarily involves powdering, forming, sintering, grinding, and finishing. The grinding machine polishes the core during processing, while a magnetic disk controls the magnetic force.

[0003] A magnetic disk is a device that can control the strength of the magnetic force. When clamping, the magnetic core is first placed on the demagnetized disk. Then the magnetic circuit switch of the disk is turned on, forming a closed magnetic circuit loop with the magnetic core, thereby attracting the core and achieving the clamping effect. However, the demagnetized state of the disk does not completely eliminate residual magnetism. This weak residual magnetism will attract magnetic material powder generated during the processing process. When this powder is on the disk, it will raise the next batch of clamped magnetic cores, causing the problem of excessive grinding volume. At the same time, the magnetic material powder is very fine and difficult to remove. If it is manually cleaned before each clamping, it will take a lot of time, reduce efficiency, and make the removal of magnetic powder waste inconvenient. To this end, we propose a residual magnetism removal device for grinding magnetic cores to solve the above problems. Utility Model Content

[0019] Compared with the prior art, the present invention provides a device for removing residual magnetism of a magnetic core processed by a grinding machine, which has the following beneficial effects:

[0020] 1. The residual magnetism removal device of the grinding machine for processing magnetic cores magnetizes and demagnetizes the magnetic core workpiece through the disk processing table. When the magnetic core workpiece is ground, it is demagnetized by the disk processing table. The ceramic isolation substrate isolates the magnetic core workpiece and the disk processing table to isolate and block the ground residual magnetic powder. The operation of the lifting hydraulic cylinder can push the ceramic isolation substrate and the magnetic core workpiece to move upward and away from the disk processing table. At this time, the residual magnetism of the disk processing table greatly weakens the attraction of magnetic material powder.

The residual magnetism removal device for processing magnetic cores of the grinder can guide the cleaning liquid in the cleaning filter box from the cleaning pipe to the cleaning nozzle through the diversion pump. The cleaning nozzle cleans and removes the magnetic powder of the magnetic core workpiece and the ceramic isolation substrate. The cleaned magnetic powder water is received by the diversion drop frame and then drops into the cleaning filter box through the wastewater diversion hose. After being filtered by the cleaning filter box, it is re-extracted for cleaning, and the circulating cleaning effect is good. The diversion drop frame prevents splashing of magnetic powder and cleaning water and collects them, which is convenient for cleaning and recycling of magnetic powder. The device has a flushing and recycling structure, which is convenient for recycling and cleaning, and improves the production efficiency and convenience of magnetic cores.

[0048] Working principle: a disk processing table 2 is provided on the main body 1 of the grinding machine processing table. First, the disk processing table 2 magnetizes the magnetic core processing part 4, and then the grinding machine processing table main body 1 grinds the magnetic core processing part 4. When the magnetic core processing part 4 is ground, the disk processing table 2 demagnetizes it, and the ceramic isolation substrate 3 isolates the magnetic core processing part 4 and the disk processing table 2 to isolate and shield the ground residual magnetic powder. A lifting hydraulic cylinder 5 is provided at the bottom of the ceramic isolation substrate 3 to drive the ceramic isolation substrate 3 to perform lifting operations. When the demagnetization and After grinding, the lifting hydraulic cylinder 5 can push the ceramic isolation substrate 3 and the magnetic core workpiece 4 to move upward and away from the disk processing table 2. At this time, the residual magnetism of the disk processing table 2 greatly weakens the attraction of the magnetic material powder, so the ceramic isolation substrate 3 can be simply rinsed with cutting fluid or cleaning fluid to remove the powder. The next batch of magnetic core workpieces 4 to be processed are placed on the ceramic isolation substrate 3, and the two are lowered together onto the disk processing table 2. The disk processing table 2 is magnetized and the next round of processing can be started. The magnetic powder removal capability is relatively convenient.

The diversion pump 7 can divert the cleaning liquid in the cleaning filter box 6 from the cleaning pipe 8 to the cleaning nozzle 9, and the cleaning nozzle 9 cleans and removes the magnetic powder of the magnetic core processing part 4 and the ceramic isolation substrate 3. The cleaned magnetic powder water is received by the diversion drop frame 10, and then diverted by the wastewater diversion hose 11, and finally diverted and dropped into the cleaning filter box 6. After being filtered by the cleaning filter box 6, it is re-extracted for cleaning, and the circulating cleaning effect is good. The diversion drop frame 10 is installed at the edge of the disk processing table 2 to prevent splashing, shield and collect magnetic powder and cleaning water, which is convenient for cleaning and recycling of magnetic powder, so that the device has a magnetic powder isolation, shielding and flushing recovery structure, has excellent magnetic powder removal ability, and is convenient for recycling and cleaning, thereby improving the efficiency and convenience of magnetic core production, and solving the problem that the magnetic powder waste generated by the existing magnetic core in the grinding production is easily magnetically adsorbed, and is difficult to be cleaned and removed manually, affecting subsequent production.
