Abstract

The invention relates to a middle supporting device used in a large-size fan blade molding process. The supporting device comprises a mounting base component, a left supporting component, a right supporting component and a middle supporting component, wherein the blade does rotational movement under the drive of an equipment main shaft, a V-shaped supporting is formed for the blade by the left supporting component and the right supporting component, two supporting included angles are automatically adjusted according to the posture of the blade, and the middle supporting component is used for dragging the low end of the blade so as to reduce sliding friction force between the blade and the left supporting component and the right supporting component. The supporting device provided by the invention can be used as an accessory of blade numerical control molding equipment and mainly used for improving the system rigidity and the automation degree in the blade winding and molding process, and meanwhile, the supporting equipment also can be used for winding and molding of other weak-rigidity workpieces.

Description

technical field [0001] The invention belongs to the technical field of manufacturing large-scale fan blades, and in particular relates to a middle support device used in the forming process of large-scale fan blades. Background technique [0002] The blade is one of the key components of the wind turbine. The blade of the wind turbine is a thin shell structure made of composite materials. It generally consists of three parts: the root, the shell, and the ribs or beams. The weight of the composite material in the entire wind turbine blade is generally Accounted for more than 90%. The blades also essentially consist of two materials, glass fiber reinforced plastic (shell, skeleton) and a foam lining. Traditional blade production generally adopts the mold-opening process, especially the hand lay-up method. During the production process, a large amount of volatile and toxic gases such as styrene will be produced, which will bring harm to the operator and the environment. On the...
