Problems solved by technology

[0003] When the magnetic ball is in use, it has the following characteristics: 1. It is divided into two balls, north and south. The main attraction part is the N / S pole at the corresponding two ends of the magnetic ball, which is usually a point of force; 2. The main material of the magnetic ball is permanent. NdFeB magnets are the most widely used in permanent magnets, but NdFeB is expensive. If the entire magnetic ball is made of NdFeB, the cost will be relatively high; 3. When grinding on the ball mill, the NdFeB powder is produced, and the falling powder is collected by a collection device, but the consumption rate and cost waste caused by reproduction are relatively large

Embodiment 1

[0035] A magnetic ball, see attached figure 1 , including a spherical magnetic ball body 1 and a magnetic core 2 arranged inside, the magnetic core 2 passes through the center of the magnetic ball body 1, and the magnetic core 2 is made of NdFeB, and the magnetic ball body 1 is made of iron or other Made of magnetic material. In order to improve the service life of the magnetic ball, a layer of coating 3 is also electroplated on the surface of the magnetic ball. The coating 3 can be chromium, tweezers or other anti-oxidation materials, which not only improves the rust resistance of the magnetic ball, but also extends the magnetic core. 2 degaussing cycles.

[0036] The production method of above-mentioned magnetic force ball, in conjunction with attached figure 1 and 2 , similar to the general production method of steel balls, the ingredients before grinding the balls are usually called cubes or cylinders, and the magnetic embryos in Example 1 are cubes. Its production ste...

Embodiment 2

[0043] A kind of method of producing magnetic ball, see attached figure 1 and 3 , The difference from Example 1 is that the magnetic embryo is cylindrical. The differences in processing are:

[0044] S1, prepare materials, take some first blanks made of magnetically conductive materials and some second blanks made of NdFeB, the first blanks are cylindrical, and the length and diameter of the first blanks are greater than or equal to the one to be prepared. The diameter of the magnetic ball made; the length of the second blank is equal to the length of the first blank;

[0045] S2, pre-processing, drilling the first blank to form an installation hole for installing the second blank, the diameter of the installation hole is less than or equal to the diameter of the second blank, and the installation hole is the same as the axis of the first blank axis.

[0046] The rest of the steps are the same as in Embodiment 1, and will not be repeated here.

Abstract

The invention relates to the field of magnetic spheres, in particular to a magnetic ball comprising a spherical magnetic ball body. A magnetic core is arranged in a way of penetrating through the center of the magnetic ball body. The magnetic core is made of Nd-Fe-B material. The magnetic ball body is made of magnetic conducting material. When the magnetic ball body is filled with the magnetic core, the suction point is located at the two ends of the magnetic core in practical use, i.e. the N/S pole. Compared with the magnetic ball completely supported by aluminum, iron and boron, the magneticsuction force at the two ends is almost unaffected and the cost is greatly reduced and thus huge economic benefits are produced.

Description

technical field [0001] The invention relates to the field of magnetic balls, and more specifically, relates to a magnetic ball and a production method thereof. Background technique [0002] Magnetic balls are more and more widely used in today's society, because of medical related parts, or related parts of toys. [0003] When the magnetic ball is in use, it has the following characteristics: 1. It is divided into two balls, north and south. The main attraction part is the N / S pole at the corresponding two ends of the magnetic ball, which is usually a point of force; 2. The main material of the magnetic ball is permanent. NdFeB magnets are the most widely used in permanent magnets, but NdFeB is expensive. If the entire magnetic ball is made of NdFeB, the cost will be relatively high; 3. When grinding on the ball mill, the Although NdFeB powder is produced and the fallen powder is collected by a collection device, the consumption rate and the cost waste caused by reproductio...
