Embodiment Construction

[0045] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0046] Such as Figure 1 to Figure 2 As shown, a method for manufacturing a rib of a wind power blade main girder mold includes the following steps:

[0047] S1. According to the rib position of the main beam, mark the positioning plate installation area 11 and the rib installation area 12 on the mold body 1;

[0048] S2, place the positioning plate 2 in the positioning plate installation area 11, and the surface of the positioning plate 2 and the rib installation area 12 forms an included angle area 3;

[0049] S3. Cover the surface of the angled area 3 with a layer of sizing cloth, paste a layer of liquid sizing agent on the sizing cloth, and form a solidified layer 4 with the sizing cloth after the liquid sizing agent solidifies;

[0050] S4, cutting the cured layer 4 according to the set shape;

[0051] S5, set baffles ...

Abstract

The invention provides a method for manufacturing flanges of a wind turbine blade girder mould and the wind turbine blade girder mould. By the method for manufacturing the flanges of the wind turbine blade girder mould, a double-flange wind turbine blade girder mould can be manufactured. After the adoption of double flanges, a double-flange girder is the same with a mould in shape, so that secondary cutting is not needed; after the girder is moulded, the girder can be directly applied to a main mould, so that the turnover time of the girder is shortened, the width of a raw material can be reduced, the using amount of resin is reduced, cutting dust is reduced, the workshop environment is improved, girder turnover is reduced, and risks of girder damage caused by the turnover are reduced.

Description

technical field [0001] The invention relates to a method for manufacturing a sidewall of a main girder mold of a wind power blade. [0002] The present invention also relates to a main beam mold of a wind power blade manufactured by using the method for manufacturing the sidewall of the main beam mold of the wind power blade. Background technique [0003] In the current manufacturing and molding process of the main beam of wind power blades, the main beam mold usually adopts a single rib, but when the single rib mold is used to manufacture the main beam of wind power blades, there are the following disadvantages: the waste of resin infused into the main beam, Increase the manufacturing cost of the blade; the main beam needs to be cut and polished, which increases the dust pollution in the workshop; due to the need for cutting and grinding, the main beam needs to be turned over, which increases the risk of damage to the main beam caused by the turnover of the main beam. The ...
