A magnetizing fixture for reducing the falling angle of magnetic tiles

Abstract

A magnetizing jig that reduces the drop angle of magnetic tiles aims to solve the problem of adjusting the geometric center of the magnetic tiles to It is very difficult to coincide with the geometric center of the magnetizing fixture, which will easily cause the technical problem of corner drop phenomenon at the R corner of the magnetic tile while affecting the surface magnetic performance of the finished product. The invention includes a base, one end of the base is provided with a magnetic core for magnetizing the product, the product includes an outer casing and an inner magnetic tile, and a guide block for assisting the positioning of the magnetic tile is arranged on the peripheral surface of the magnetic core. The end face close to the magnetic core is provided with a positioning piece to assist the positioning of the casing, and the peripheral surface of the magnetic core is provided with a flexible limit group to prevent the magnetic tile from colliding with the magnetic core. A plurality of flexible limiting parts, under the cooperation of the guide block, the positioning part and the flexible limiting group, the magnetic tile, the casing and the magnetic core are coaxially arranged.

Description

technical field [0001] The invention relates to the technical field of magnetic material manufacturing, in particular to a magnetizing fixture for reducing the drop angle of magnetic tiles. Background technique [0002] The principle of the magnetizing coil is that the energized solenoid generates an induced magnetic field. The magnetic field strength is related to the energizing current and the number of coil turns. Under the same magnetizing current intensity, the more coil turns, the greater the magnetic field strength. In the prior art, magnetizing fixtures are often used to fix the product to be magnetized and then perform magnetization operation. When the product to be magnetized has a double-layer structure with magnetic tiles, the magnetic tiles that obtain magnetism instantly will collide with the magnetic tiles of the magnetizing fixture. If the core collides, since pig iron is often used as the preparation material of the magnetic core, the magnetic tile colliding...

Problems solved by technology

[0005] The present invention overcomes the difficulty in adjusting the geometric center of the magnetic tile to coincide with the geometric center of the magnetizing fixture when using the magnetizing fixture to magnetize the product to be magnetized with a double-layer structure with magnetic tiles in the prior art. Large, while affecting the surface magnetic performance of the finished product, it is easy to cause the technical problem of the drop-off phenomenon at the R corner of the magnetic tile. A magnetizing fixture that reduces the drop-off angle of the magnetic tile is provided. The magnetic core of the magnetizing fixture is provided with a limit position On the one hand, the limiter can prevent the magnetic tile from colliding with the magnetic core, avoiding the phenomenon of falling angle at the R corner of the magnetic tile, on the other hand, it can ensure that the magnetic core and the magnetic tile have good concentricity, and solve the problem of permanent magnet After the magnetic material product is magnetized, there are problems with the magnetic performance and magnetic declination of each pole surface, thereby improving the magnetic performance and yield rate of the product
