Embodiment Construction

[0028] The fan blade root preform forming method and the root preform mold according to the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] The fan blade root preform forming method of the present invention is used for forming the root preform of the blade of the wind power generator. Of course, under the enlightenment of the technical thought of this forming process, it can also be transferred to forming other structures.

[0030] The fan blade root preform molding method of the embodiment of the present invention is to use the root preform mold 10 whose molding surface 11 is an upward convex surface to produce the root preform.

[0031] The technical principle for solving technical problems is to use the root preform mold 10 with the molding surface 11 as an upward convex surface to form the root preform. Because the molding surface 11 is convex, it can effectively prevent the glass fiber cloth laid...

Abstract

The invention provides a molding method for a prefabricated root part of a fan blade and a prefabricated root part mold. The molding method for the prefabricated root part of the fan blade includes the following steps that S01, a glass fiber cloth layer is laid on a molding surface of the prefabricated root part mold, and the molding surface of the prefabricated root part mold is a convex surface facing upwards; and S02, the laid glass fiber cloth layer is soaked in resin, and the prefabricated root part is formed. According to the molding method for the prefabricated root part of the fan blade, the molding surface of the prefabricated root part mold is the convex surface facing upwards, so that the glass fiber cloth layer is protected against wrinkles, and a better molding effect is achieved.

Description

technical field [0001] The invention relates to the field of wind power generator blade processing, in particular to a method for forming a fan blade root prefabricated part and a mold for the root prefabricated part. Background technique [0002] The root area of ​​the fan blade bears the load transmitted from the entire blade. In order to ensure reliability and durability, the root of the blade needs to use many layers of glass fiber cloth when designing. In order to improve the use efficiency of the shell mold, prevent the root layer of the blade from wrinkling, reduce the maintenance and scrap caused by it, and reduce the scrap caused by perfusion leakage, in the blade production process, most of the glass fiber at the root of the blade is usually Cloth uses a separate mold to form the root preform, which is then placed in the shell mold and molded together with the other components. Root prefabrication technology can be used to produce root perforated blades and root e...
