Problems solved by technology

This method has a long cycle, and the amount of structural adhesive is about 200-250kg / time, and the used structural adhesive can only be scrapped. Therefore, it is expensive to design the shape of PVC foam according to this method, and it will inevitably cause a lot of waste when the blade changes frequently. waste and pollution

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Figure 1 to Figure 3 A kind of embodiment of the PVC foam design method of wind power blade trailing edge clamping molding of the present invention is shown, comprising the following steps:

[0027] S1: Blade shell forming: According to the blade shell forming process, make the PS surface shell 1 and SS surface shell 2 of the shaped blade;

[0028] S2: Place the plasticine: place the plasticine 4 along the rear edge 3 of the SS surface, the plasticine 4 must run through the entire rear edge bonding surface, and the height of the plasticine 4 is higher than the height of the rear edge cavity;

[0029] S3: Press plasticine: Turn over the PS surface mold and lock it to obtain a plasticine compact that matches the cavity of the trailing edge of the blade, cut the plasticine 4 along the cross section, and obtain the cross-sectiona...

Abstract

The invention discloses a wind power blade posterior-edge die spotting PVC foam design method. The method comprises the following steps: S1, forming blade shell bodies; S2, placing plasticine; S3, pressing the plasticine; S4, drawing PVC foam contour coordinates; S5, drawing a PVC foam contour graph; and S6, refinedly drawing a PVC foam section drawing. The method has the advantages that operations are convenient, economic benefits are high, and design costs can be reduced.

Description

technical field [0001] The invention mainly relates to the size design of the PVC foam filled gap used in the mold closing gap of the trailing edge of the wind power blade in the field of wind power blade production, and in particular to a design method of the PVC foam for the trailing edge of the wind power blade. Background technique [0002] With the advancement of national energy conservation and emission reduction policies, green and environmentally friendly energy is the key development direction in the future. Wind energy has the advantages of low energy consumption, environmental protection, and large reserves, and has become a key energy source for development at home and abroad. A wind turbine is a device that converts wind energy into electrical energy. The blade is one of the core components of the wind turbine. In the production process of the blade, the mold clamping process is the most important forming process, and the mold clamping gap is a crucial parameter....
