Problems solved by technology

Although the above method can ensure the accurate positioning of the web on the SS shell of the blade, during the mold closing process, the web is easily slipped with the PS shell due to being squeezed by the PS shell, forming prestress and affecting the quality of the blade
In addition, the traditional mold closing method cannot effectively control the thickness of the adhesive glue on the upper and lower surfaces of the web, which may easily cause local lack or excess of the amount of adhesive glue between the web and the shell, thereby affecting the quality of the blade

Abstract

The invention discloses a method for adhering blades of a megawatt wind turbine in die assembly, which comprises the following steps of: arranging positioning control blocks at blade SS shell and blade PS shell web adhering positions; coating an adhesive at an SS shell internal web adhering position and an upper surface of a web; arranging gap control blocks at a blade SS shell web adhering position and the upper surface of the web respectively; coating the adhesive on the front and back edges of the blades; hoisting the web between the positioning control blocks in the shells; and turning over the PS shell, and curing the adhesive in the blades together to adhere the SS shell, the PS shell and the web into a whole. In the method, the web can be accurately positioned and prevented from sliding, and the consumption of the adhesive can be controlled randomly and is prevented from being locally deficient or excessive; in addition, the adhesive at all adhering positions is cured at one time in the die assembly process, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a method for manufacturing components of wind power generation equipment, in particular to a die-clamping and bonding method for megawatt-level wind power blades, which is mainly used for making large-scale wind power blades. It belongs to the technical field of wind power generation. Background technique [0002] Wind turbine blades are one of the key components of wind turbines, and their design life is usually 20 years. At present, the most commonly used wind power blade is the horizontal axis wind power blade, which is mainly composed of suction side (SS) shell, pressure side (PS) shell and shear web bonded by adhesive. Adhesive bonding defects will lead to a sharp decrease in the fatigue life of the blade or even cracks, and the relative position of the web in the shell also has an important impact on the quality of the blade. Therefore, the mold clamping and bonding quality of wind turbine blades is closely related to t...
