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
The present invention relates to a kind of magnetization method of permanent magnetic crane magnetic, relate in particular to a kind of magnetization method of magnetic component of permanent magnetic crane.
Background technology
Permanent magnetic crane adopts high-performance Ne-Fe-B permanent-magnet material, and it is little, strong from heavy and light, suction to have a volume, and not electricity consumption is safe and reliable.Unique magnetic Circuit Design, remanent magnetism is almost nil when closing, the coefficient of safety advantages of higher, the lifting that is widely used in steel is carried, smooth machine components, and the installation and the carrying of various moulds.
Current, the magnetization method of magnetic component of permanent magnetic crane: earlier permanent magnet is magnetized, again with the magnetic magnet crane of packing into.From effect, there is very big repulsive interaction power between the magnetic magnet, difficulty is very big in assembling process; Even magnet occurs and eject; Security incident occurs, (specified lifting power >=1000Kgf) is because the magnet volume that will assemble is big, quantity is many for large-scale permanent magnetic crane; Magnet interphase interaction power is big, almost can't assemble with original way.
Summary of the invention
The present invention is directed to deficiency of the prior art, a kind of magnetization method of magnetic component of permanent magnetic crane is provided, this magnetization method can make things convenient for, like a cork the permanent magnetic material in the magnet assembly fixed.
In order to solve the problems of the technologies described above, the present invention is able to solve through following technical proposals: step 1: with permanent magnetic material, and gluing on the face; Bond together, form assembly, step 2: it is inserted in the crane; And fix loam cake, step 3: permanent magnetic material is magnetized with magnet charger.
Beneficial effect: the present invention compared with prior art has following beneficial effect: because permanent magnetic material did not magnetize before device, do not have active force between permanent magnetic material and the permanent magnetic material; The minitype permanent magnetism crane greatly reduces assembly difficulty; Be easy to assembling, and magnet can not eject, stop the generation of security incident; (difficult problem of specified lifting power >=1000kgf) can't assemble has realized the batch process of large-scale permanent magnetic crane to have solved large-scale permanent magnetic crane.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
Fig. 1, among Fig. 2,1 coil, 2 permanent magnetic material main components are neodymium iron boron (NdFeB), 3 cranes, 4 cartridges, 5 magnetic loop iron plates.
The magnetization method of magnetic component of permanent magnetic crane, its method step: with permanent magnetic material 2, gluing on the face bonds together, and forms assembly, it is inserted in the crane 3, and cover the box lid.
After the installation, it is magnetized, said crane 3 places in the middle of the cartridge 4, and cartridge 4 surrounds a turn coil 1, and the outer setting of coil 1 has magnetic loop iron plate 5.
When magnetizing, when the said coil current that magnetizes was 300A, generation magnetic field was 30000GS, made permanent magnetic material 2 magnetic saturations.
Claims (3)
