Problems solved by technology

Due to the position of the front glue in the blade, it is difficult to cure. It can only be cured by the waste heat of the blade mold, which makes it difficult to guarantee the curing quality and affects the product quality.

Embodiment 1

[0035] Such as figure 1 Shown, a kind of method for making the blade front bonding mold with heating function, it comprises the following steps:

[0036] a. First confirm the manufacturing range of the leading edge pasting angle mold according to the blade shape;

[0037] b. Clean the surface of the main mold in the corresponding production areas of the windward side 1 of the blade and the leeward side 4 of the blade, and apply a release agent;

[0038] c. After the release agent is solidified and formed into a film, lay a layer of release cloth on the front edge of the windward side 1 of the blade, and then fix it with a small amount of spray glue to make it fit the main mold, and then hand-paste a layer of biaxial cloth , the width of glass fiber cloth is different in different positions;

[0039] d. Lay reinforced fiber cloth 2 on the inner surface of the mold at the edge of the boss of the main mold;

[0040] e. Place the core material 3 on the main mold flange platform...

Abstract

The invention discloses a method for manufacturing a blade front paste mold with a heating function. The method comprises the steps that demolding cloth is firstly laid on the front edge of a blade windward side (1), and then dual-shaft cloth is subjected to hand layup; a core (3) is put onto a main mold flange platform; fiber cloth is laid to cover the whole area of the blade windward side (1) and a blade leeside (4), then demolding cloth is laid, and a vacuum system is laid on a main mold; fiber cloth is laid on the front edge area of the blade leeside (4) in a hand layup manner, and the surface is covered with demolding cloth; and after a mold of the blade leeside (4) is cured, the demolding cloth on the surface is torn off, then an adhesive (5) is arranged on the surface through a putty knife in a scraping manner, and then mold compounding and curing are carried out. The method is reasonable in process design and high in operability; the front pasting and heating mold is manufactured through an integrated pouring forming process; blade front edge pasting angle curing is facilitated; deformation and defects caused by poor curing can be reduced; and a front edge obtained through preparation is high in pasting precision and good in quality.

Description

technical field [0001] The patent of the present invention relates to a method for preparing a wind turbine blade accessory of a wind power generating set, in particular to a method for manufacturing a blade front bonding mold with a heating function. Background technique [0002] In the current production process of the blade, the bonding angle of the leading edge of the blade (referred to as the front bonding) is an important part of the reinforcement of the bonding of the upper and lower sides of the blade shell, and is one of the effective means to increase the bonding performance of the blade shell. The production quality of the edge sticking angle will directly affect the bonding performance of the two-sided shell. There are two methods of production: wet method and vacuum infusion molding. The current production of the front sticking corner is based on the leading edge sticking corner mold to make. Due to the position of the front glue in the blade, it is difficult t...
