Abstract
The invention discloses a rotor formed by one-time punch forming and a manufacturing method thereof, wherein the rotor comprises a rotor core, n salient poles are arranged on the rotor core, n is more than or equal to 4, the salient poles are uniformly distributed on the outer wall of the rotor core, bosses are arranged at the end parts of the salient poles, the salient poles and the rotor core are of an integrated punch forming structure, and the rotor core and a plurality of convex stages have the same density and magnetism. The rotor making process includes heating special steel material, ultrahigh forging and pressing to form the rotor product with very high compactness. Due to the fact that ultrahigh forging and pressing are used for forming, consistency of density of all parts is fully improved, balance of magnetism is effectively improved, the magnetism is stronger, the magnetism is kept for a longer time, and power is greatly improved; meanwhile, the concentricity of rotor processing is improved; due to one-step forming, the method completely replaces the traditional stator punching lamination laminating method, reduces the investment of equipment and the loss of tools, and reduces the processing amount of products.
Description
Technical Field
The invention relates to the technical field of motors, in particular to a rotor formed by one-time stamping and a manufacturing method thereof.
Background
With the increasing demand of the industrial field and the civil field for product intellectualization, the mode of the single generator outputting electric power in the traditional generator field can not meet the application of some special fields, or the application of the current industrial field to the generator is basically established on the basis of the structure of the single generator. The traditional motor rotor is mostly processed by adopting a method of lamination of punching sheets, the concentricity is difficult to reach the high standard, swing and resonance are generated during rotation, the stator and the rotor are likely to have friction, the noise is high, the electricity is wasted, in order to keep good concentricity, the requirement on processing precision is high during processing, the equipment investment is large, and the tool loss is large.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention provides a rotor formed by one-time stamping and a manufacturing method thereof.
In order to achieve the purpose, the invention provides the following technical scheme:
rotor of disposable stamping forming, including rotor core, rotor core has arranged n salient pole on, and n is greater than or equal to 4, the salient pole equipartition is in rotor core outer wall, the salient pole tip is equipped with the boss, salient pole and rotor core are stamping forming structure as an organic whole, the density of rotor core and a plurality of protruding grades is unanimous and has magnetism.
And a through hole is formed in the middle of the rotor core.
The rotor making process includes heating special steel material, ultrahigh forging and pressing to form the rotor product with very high compactness.
The invention has the technical effects and advantages that: due to the fact that ultrahigh forging and pressing are used for forming, consistency of density of all parts is fully improved, balance of magnetism is effectively improved, the magnetism is stronger, the magnetism is kept for a longer time, and power is greatly improved; meanwhile, the concentricity of the rotor processing is improved, the swing and resonance during the rotation are reduced, the possibility of friction between the stator and the rotor is reduced, the noise is reduced, and the electric energy is saved; due to one-step forming, the method completely replaces the traditional stator punching lamination method, reduces the investment of equipment and the loss of tools, reduces the processing amount of products, promotes the products in unit time and improves the market competitiveness.
