Core material thickness chamfering method of fan blade

Abstract

The invention discloses a core material thickness chamfering method of a fan blade. The core material thickness chamfering method comprises the following steps of setting a height between a cutting head of cutting equipment and a working table of the cutting equipment; setting a relative angle between a saw blade of the cutting head and the working table of the cutting equipment; pushing in a corematerial in a direction perpendicular to the extending direction of the saw blade of the cutting head; and removing a to-be-chamfered portion of the upper part of the core material by the saw blade of the cutting head in a pushing-in direction. Chamfering is performed by the cutting equipment, a chamfer of the core material can be accurately cut by high-speed linear moving of the saw blade of thecutting equipment, continuous cutting can be performed by the saw blade of the cutting head during high-speed movement, the feeding speed of the core material cannot be affected even under the conditions of very small chamfer angle of the core material and wide cutting area, and very high cutting efficiency can also be ensured by the saw blade of the cutting head.

Description

technical field [0001] The invention relates to a method for chamfering the thickness of the core material of fan blades. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge, and the global wind energy is about 2.74×10 9 MW, of which the available wind energy is 2×10 7 MW is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. Wind power generation is very suitable for coastal islands, grasslands, pastoral areas, mountainous and plateau areas that lack water, fuel, and inconvenient transportation. The use of wind power according to local conditions is very suitable and promising. [0003] The wind power generation unit includes a wind rotor and a generator, and the wind rotor includes blades, hubs, reinforcements, etc. The blade is the most basic and critical part of the wind turbine. Its good design, reliab...
