Embodiment Construction

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0052] see figure 1 and figure 2 As shown, the wind turbine blade is the core component of the unit, including a suction side shell and a pressure side shell, and the suction side shell and the pressure side shell are bonded by an adhesive to form a complete blade structure. Wherein, the suction side shell, that is, the leeward side shell 20 may also be called the SS side shell (suction side). Wherein, the pressure side shell, that is, the windward side shell 10...

Abstract

The invention discloses a method for manufacturing a blade mold of a wind driven generator. The method for manufacturing the blade mold of the wind driven generator at least comprises the following steps that molding data of a bonding angle are acquired according to a blade shell mold; according to a datum plane intersecting with the blade shell mold, an intersecting line of the blade shell mold and the datum plane is obtained; the intersecting line is offset, and the offsetting intersecting line is connected through a curved surface to obtain a parting surface of a bonding angle mold; according to the parting surface and the molding data, modeling data of the bonding angle mold are obtained; a male mold model is established according to the modeling data and processed to obtain a male mold; and according to the male mold, a laying layer is laid, and the bonding angle mold is obtained through processing. According to the mold and the manufacturing method thereof, the bonding strength of a windward side shell and a leeside shell of a wind driven generator blade can be improved.

Description

technical field [0001] The invention belongs to the field of wind power blade manufacturing, and in particular relates to a method for manufacturing a wind power generator blade mold. Background technique [0002] Wind turbine blades are the most basic and core components of wind power generation systems. Their good design, reliable quality and superior performance are the decisive factors to ensure the normal and stable operation of the unit. During the manufacturing process of the wind power generation blade, when the suction side shell and the pressure side shell are bonded, a transitional bonding angle needs to be made between the suction side shell and the pressure side shell. The quality of the bonding corner mold determines the quality of the bonding corner, and also determines whether the thickness of the structural adhesive in the bonding corner area of ​​the front and rear edges meets the design requirements, and whether it can meet the bonding strength of the bond...
