Method for magnetizing magnetic component of permanent magnetic crane

Abstract

The invention discloses a method for magnetizing a magnetic component of a permanent magnetic crane. The magnetizing method can conveniently and easily fix a magnet in the magnetic component. The method comprises the steps: 1, gluing the surface of a permanent magnetic material and adhering together to form a component; 2, placing the permanent magnetic material into the crane and fixing an upper cover; and 3, magnetizing the permanent magnetic material by a magnet charger. Because the magnetization is not carried out before the device, no acting force exists between the permanent materials, therefore, a small-scale permanent magnetic crane greatly reduces the assembly difficulty and is easy to assemble, and the permanent material can not be popped up so as to prevent the occurrence of safe accidents, solve the difficulty that a large-scale permanent magnetic crane (more than or equal to 1000kgf of a rated lifting force) cannot be assembled and realize the batch production of the large-scale permanent magnetic crane.

Description

technical field [0001] The invention relates to a magnetic magnetization method of a permanent magnet crane, in particular to a magnetization method of a magnetic component of a permanent magnet crane. Background technique [0002] The permanent magnet crane adopts high-performance NdFeB permanent magnet material, which has the advantages of small size, light weight, strong suction, no electricity, safe and reliable. Unique magnetic circuit design, almost zero residual magnetism when closed, high safety factor, etc., widely used in lifting and handling steel, flat mechanical parts, and installation and handling of various molds. [0003] At present, the magnetization method of the magnetic components of the permanent magnet crane: first magnetize the permanent magnet, and then load the magnetic magnet into the crane. From the effect point of view, there is a large mutual repulsion force between the magnetic magnets, which is very difficult in the assembly process, and even ...

Problems solved by technology

[0006] Beneficial effects: Compared with the prior art, the present invention has the following beneficial effects: Since the permanent magnet material is not magnetized before the installation, there is no force between the permanent magnet material and the permanent magnet material, and the small permanent magnet crane greatly reduces the difficulty of assembly , easy to assemble, and the magnet will not pop out, which prevents the occurrence of safety accidents, solves the problem that large permanent magnet cranes (rated lifting force ≥ 1000kgf) cannot be assembled, and realizes the mass production of large permanent magnet cranes
