Abstract
The invention provides a preparation method of a wind turbine blade web mold. A material used is stainless steel. The preparation method of the wind turbine blade web mold comprises the following steps that first, an upper-layer web panel, a lower-layer web panel, a baffle and a supporting plate are cut and processed according to requirements, and then a web supporting frame is made; a heating layer is paved on the upper part of a mold supporting frame; a thermal insulation layer is paved on the upper part of the heating layer; the web mold is subjected to welding molding by adopting an integrated molding welding method; a plurality of vacuum holes are formed in the upper-layer web panel and the lower-layer web panel in the transverse direction of the mold, a interval distance between eachtwo adjacent vacuum holes is 3.1-3.5 m, and the outer part of each vacuum hole is connected with a vacuum pump; and the complete wind turbine blade web mold is prepared when the steps are finished. According to the preparation method of the wind turbine blade web mold, the work efficiency is improved and the cost is saved by adopting the integrated molding method, and the machined mold has the advantages of being not prone to being deformed and reusable.
Description
technical field [0001] The invention belongs to the field of a mold preparation method, and in particular relates to a preparation method of a wind power blade web mold. Background technique [0002] Wind turbine blades usually consist of three parts: skin, beam, and web. Among them, the web plays a supporting role in the inner cavity of the blade and bears the main load of the blade during the movement process, and the forming of the web needs to be produced by a web mold. Due to the particularity of the shape of the blades, the molds for the manufacture of wind power blades are also specific. After the 2-3 year life cycle of the entire blade is over, the corresponding molds are difficult to be used for the production of other types of blades, making the use of molds low rate. At the same time, the web molds used for different types of blades are different. When multiple types of blades are required, a corresponding number of web molds must be configured, and finally the ...
