Novel method for manufacturing wind turbine blade rib plate die

Abstract

The invention relates to a novel method for manufacturing an ultra-large type wind turbine blade rib plate die. The die consists of bonding corners, rib plates, die steel frames, glass shell dies and heating layers. During manufacturing, the die steel frames are manufactured first, two sides of each shell die are cut to form contours according to the sizes of the rib plates, and the glass shell dies are welded at the corresponding positions of the die steel frames; the heating layers and vacuum tubes are arranged underneath the glass shell dies and are used for heating and vacuum processing during manufacturing of blade rib plates; and die steel plates are manufactured by a method of spot welding and splicing, base plate spot welding and exterior coating of glass reinforced plastic in the length directions of the glass shell dies. The method has the advantages that the dies which are manufactured by using the steel plates can transfer heat quickly and uniformly, the surfaces of the dies are not deformed and high in flatness, the blade rib plates are perpendicular to the axis direction and can be adjusted, and the problem of air leakage of the connection part of a die which is manufactured by using the ultra long blade rib plate all-steel plates is solved by the method of spot welding, base plate spot welding and exterior coating of glass reinforced plastic simultaneously; the inclination angles of the bonding corners can be adjusted slightly; sheet steel is adopted, a tip part can be bent; and the method is suitable for manufacturing complex blade rib plate dies.

Description

technical field [0001] The invention relates to a manufacturing method of a novel super-large wind power blade stiffener mold. Background technique [0002] Ultra-large wind power blade mold refers to a female mold with a length greater than 50m and a weight greater than 40t on one side. At present, the molds of the domestically produced blades are all manufactured as a whole. For safety considerations, railways, highways, etc. have restrictions on the length and height of transported goods, which has caused difficulties in transporting the die and high transport costs. At the same time, due to the huge size of the blade mold, the demand for mold manufacturing space is also relatively large, and the requirements for production space are relatively high. Contents of the invention [0003] The object of the present invention is to provide a method for making a novel super-large wind power blade stiffener mold. [0004] The invention proposes a manufacturing method of a no...
