Abstract
Interior permanent magnets mine explosion-suppression permanent magnetic electric barrel, including cylinder shell (A), rotor punching (1) and permanent magnet (2), rotor punching (1) is whole stamping, there is permanent magnet inlaid hole in whole stamping, rotor punching (1) hot jacket forms superimposed permanent magnet inlaid hole after entering in roller, permanent magnet (2), which is inlaid in superimposed permanent magnet inlaid hole, forms interior permanent magnets.Compared with prior art, the utility model has the advantage that 1. punching entirety punching press is completed, and after superposition, rear hot jacket enters in roller, avoids punching, sheet punching press precision height, permanent magnet can guarantee that not same pole permanent magnet does not deviate.Processing and assembly simplify more.2. the oxidation to permanent magnet is also greatly improved.Since permanent-magnet type shape is changed to cuboid, the processing is simple, saves waste.3. permanent magnet postpones in being changed to, rotor surface loss is reduced, efficiency is improved, meanwhile, it prevents magnetic pole surfaces temperature excessively high, avoids permanent magnet because of high temperature loss of excitation.
Description
Technical field
The utility model relates to a kind of mine explosion-suppression permanent magnetic electric barrel, especially a kind of interior permanent magnets mine explosion-suppression
Permanent magnetic electric barrel.
Background technique
Currently, the mine explosion-suppression permanent magnetic electric barrel of the prior art, permanent magnet are tiles, not only processing is complicated, wastes material
Material, it is at high cost；And permanent magnet leans against the threaded hole processed in cylinder shell and is fixed with bolt, the thread mill drilling in cylinder shell,
It is fixed by bolts, not only installation trouble, also occurs installation damage permanent magnet situation sometimes；And threaded hole position precision controls
It is bad, cause permanent magnet not install, be installed after the case where same pole permanent magnetism solid offsetting occur occur often.Because of permanent magnetism
Body directly it is exposed in air, it is poor to the oxidation protection of permanent magnet, directly acted on forever in motor course of work high temperature
On magnetic material, permanent magnet loss of excitation will lead to.Therefore, a kind of interior permanent magnets mine explosion-suppression permanent magnetic electric barrel is designed, is mesh
The preceding technical issues that need to address.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of rollings of interior permanent magnets mine explosion-suppression permanent-magnet electric
Cylinder.
The technical scheme in the invention for solving the technical problem is:
Interior permanent magnets mine explosion-suppression permanent magnetic electric barrel, including cylinder shell, rotor punching and permanent magnet, rotor punching
For whole stamping, formed after thering is permanent magnet inlaid hole, whole stamping hot jacket to enter in roller on rotor punching superimposed
Permanent magnet inlaid hole, permanent magnet, which is inlaid in superimposed permanent magnet inlaid hole, forms interior permanent magnets.
As a kind of preferred embodiment of the utility model, the type shape of the permanent magnet is cuboid.
Compared with prior art, the utility model has the advantage that
1. punching entirety punching press is completed, after superposition, rear hot jacket enters in roller, avoids punching, sheet punching press precision is high, forever
Magnet can guarantee that not same pole permanent magnet does not deviate.It is to processing and assembly to simplify more.2. also having greatly to the oxidation of permanent magnet
The raising of amplitude.Since permanent-magnet type shape is changed to cuboid, the processing is simple, and material is not wasting.3. permanent magnet postpones in being changed to,
Rotor surface loss is reduced, efficiency is improved, meanwhile, it prevents magnetic pole surfaces temperature excessively high, avoids permanent magnet because of high temperature loss of excitation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the prior art；
Fig. 3 is the enlarged view at I of figure.
Specific embodiment
As shown, interior permanent magnets mine explosion-suppression permanent magnetic electric barrel, including cylinder shell A, rotor punching 1 and permanent magnetism
Body 2, which is characterized in that rotor punching 1 is whole stamping, there is permanent magnet inlaid hole, 1 heat of rotor punching in whole stamping
Superimposed permanent magnet inlaid hole is formed after being inserted in roller, permanent magnet 2 is inlaid in superimposed permanent magnet inlaid hole and is formed
Interior permanent magnets.The type shape of the permanent magnet 2 is cuboid.
Claims (2)
1. interior permanent magnets mine explosion-suppression permanent magnetic electric barrel, including cylinder shell (A), rotor punching (1) and permanent magnet (2),
It is characterized in that, rotor punching (1) is whole stamping, there are permanent magnet inlaid hole, rotor punching (1) heat in whole stamping
Superimposed permanent magnet inlaid hole is formed after being inserted in roller, permanent magnet (2) is inlaid in shape in superimposed permanent magnet inlaid hole
At interior permanent magnets.
2. interior permanent magnets mine explosion-suppression permanent magnetic electric barrel according to claim 1, which is characterized in that it is described forever
The type shape of magnet (2) is cuboid.
