Magnetic ball and production method thereof

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...
