Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core production, in particular to a deburring device for magnetic core production. Background Art

[0002] A magnetic core refers to a sintered magnetic metal oxide composed of a mixture of various iron oxides. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical magnetic core materials. Manganese-zinc ferrite has the characteristics of high magnetic permeability and high magnetic flux density, and has the characteristics of low loss. Nickel-zinc ferrite has extremely high resistivity and low magnetic permeability of less than a few hundred. Ferrite cores are used in coils and transformers of various electronic devices.

[0003] After the magnetic core is processed, it needs to be deburred. Generally, a magnetic polishing machine is used for polishing and deburring. The magnetic polishing machine generates a magnetic field to drive the tiny steel needles in the cylinder to rotate. The steel needles continuously knock on the magnetic core to achieve deburring, which is convenient and fast. However, all the magnetic cores are located in the cylinder, and the steel needles will drive the magnetic cores to rotate at the same time. Collisions may occur between the magnetic cores, resulting in surface scratches. At the same time, the cylinder is large and there are many steel needles. It is difficult to remove the steel needles when cleaning. For this reason, we propose a deburring device for magnetic core production. Utility Model Content

The upper ends of the fixed disks are connected to the evenly distributed fixed blocks through bolts. The fixed blocks correspond to each other in pairs, and the magnet blocks are fixedly connected between the two corresponding fixed blocks.

[0008] Deburring mechanism: It is placed inside the compartments respectively. The deburring mechanism corresponds to the upper and lower positions of the vertically adjacent fixed disks respectively. The magnetic cores are separated by multiple compartments for polishing and deburring to avoid scratches caused by collision between the magnetic cores, and it is convenient for cleaning the steel needles.

[0009] Furthermore, it also includes a control switch, which is arranged on the upper surface of the support plate, and the input end of the control switch is electrically connected to an external power supply to control the motor to start.

The lower ends of the rotating shafts 2 except the rightmost rotating shaft 2 at the front end are fixedly sleeved with two synchronous pulleys 2, and the lower end of the rightmost rotating shaft 2 at the front end is fixedly sleeved with a synchronous pulley 2. The two synchronous pulleys 2 at the upper end of the rightmost rear end and the upper end of the middle part and the two synchronous pulleys 2 at the lower end of the leftmost front end and the lower end of the middle part are all connected for transmission through the synchronous belts 3 adjacent to each other on the left and right. The two adjacent synchronous pulleys 2 on the left and right are rotationally connected through the synchronous belts 2 to realize synchronous rotation of the fixed disk.

[0011] Furthermore, the magnetic drive mechanism also includes a synchronous pulley, a motor and a synchronous belt. The left side of the bottom wall of the base is rotatably connected to the synchronous pulley via a rotating shaft.

The steel needle continuously collides with the magnetic core to realize the polishing and deburring of the magnetic core. The magnetic core is separated in different cylinders for deburring, which avoids the situation where collision between the magnetic cores causes scratches. BRIEF DESCRIPTION OF THE DRAWINGS
