A method for producing wind blades of a generator

Abstract

The invention discloses a production method of a fan blade of a generator, comprising the following steps: S1, using high pressure to forcibly press a metal solution into a high-precision mold, and cooling to obtain a fan blade blank with a through hole in the middle; S2, a wind direction blade A metal ring with an open structure is pressed into the through hole of the blank, and the metal ring is bonded to the inner wall of the through hole; S3, removing the burrs on the edge of the fan blade blank; S3, grinding the edge of the fan blade blank until there is no obvious protrusion, Obtain the fan blade of the generator; S4, use the flatness detection equipment to detect the flatness of the back of the fan blade; if the detected fan blade is qualified, enter the next detection link. The invention ensures that the fan blades installed on the output shaft of the generator can reach a state of dynamic balance when they are rotating, so as to avoid damage to the generator.

Description

technical field [0001] The invention belongs to the technical field of fan blade products, and in particular relates to a production method of a generator fan blade. Background technique [0002] Generator blades, also known as flywheels, are connected to the output shaft of the generator and rotate at a high speed synchronously with the output shaft, and then the blades form wind next to the generator to achieve the purpose of cooling the generator; currently Some generator fan blades are made by injecting molten solution into the mold, and then die-casting under high pressure. Finally, after deburring and polishing the edges, they are boxed, and finally installed directly on the output shaft of the generator. [0003] However, due to the poor precision of the mold during die-casting, or other external factors, it is easy to cause the thickness of the die-cast fan blade to fail to meet the standard and the surface is uneven. If the thickness does not meet the standard and t...

[0003] However, due to the poor precision of the mold during die-casting, or other external factors, it is easy to cause the thickness of the die-cast fan blade to fail to meet the standard and the surface is uneven. If the thickness does not meet the standard and the surface is uneven When the fan blade is installed on the output shaft of the generator, when the generator shaft rotates with the fan blade, the fan blade cannot reach dynamic balance, and there is an eccentric force in the rotating fan blade; the eccentric force pulls the generator output in the vertical direction The output shaft of the generator will be damaged under long-term high-speed rotation, which will further cause the internal parts of the generator to shift and damage the generator
