Problems solved by technology

Therefore, there are at least the following disadvantages in the existing method for making the rough surface of the blade surface of a wind power generating set: blade surface grinding, scraping putty, and polishing putty all require manual operations in the blade manufacturing process, which is not only time-consuming and laborious, but also increases labor costs; The dust generated by the grinding operation will also pollute the environment; in addition, scraping putty not only increases labor costs, but also wastes raw materials and increases material costs

Embodiment Construction

[0022] Embodiments of the present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

[0023] The following will combine Figure 1 to Figure 3 A method for manufacturing a blade of a wind power generating set according to an exemplary embodiment of the present invention is described in detail. However, the scope of application of the present invention is not limited to blades of wind power generators, and the present invention can also be applied to the manufacture of blades used in other equipment.

[0024] The molds used to make wind turbine blades are divided into suction surface (SS surface) molds and pressure surface (PS surface) molds to prepare suction surface blade moldings and pressure surface blade moldings of wind turbine blades. Then, the mold on the pressure side is turned over 180° to be bonded with the mold on the suction side, and finally demolded. The manufacturin...

Abstract

The invention provides a blade manufacturing method and a blade. The blade manufacturing method comprises following steps that a rough mask is laid on a blade mold; a blade forming material and a vacuum infusion system are laid on the rough mask; a vacuum infusion method is adopted to infuse resin into the blade forming material to be cured, and a blade forming part with the rough surface is formed. The blade comprises the blade forming part prepared through the manufacturing method and a paint layer covering the rough surface of the blade forming part. Through the blade manufacturing method,dust pollution can be avoided, the blade production period can be shortened, and the blade production cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of blades, and more specifically, to a manufacturing method of blades and the blades obtained therefrom. Background technique [0002] At present, the vacuum-assisted forming process is usually used in the forming process of wind turbine blades. That is, under certain negative pressure conditions, the resin is injected from the outside into the reinforcing material, and then solidified and formed. The cured and formed blades enter the post-processing process after going through the mold clamping process and the demoulding process. The surface of the blade obtained after demoulding is a smooth surface, therefore, in the post-processing process, it is necessary to process a rough surface on the surface of the blade to roll paint. For this reason, in the post-processing process, it is necessary to polish the surface of the blade. After grinding and cleaning the dust on the surface of the blade, scrape...
