Die for manufacturing blades with multiple sizes for wind driven generator

Abstract

The invention discloses a die of a blade for an air blower, which consists of a plurality of sections of dies. The different sections of the dies are connected through a combination device, so that blades with different sizes are manufactured. The die divides a blade die into four sections, and each section comprises a plurality of options. By changing the sizes of a blade point die, a blade middle part die and a blade root die, the die can be used for manufacturing the blade with the other size from the manufacturing of the blade with one size. Meanwhile, at the beginning of a die manufacturing process, the manufacturing process of the blades with one or two sizes can be covered, and then blade assemblies with corresponding sizes can be additionally arranged according to the production demands. The die provided by the invention has the beneficial effects that the blades with the multiple sizes can be manufactured by one set of die, so that the cost is reduced; the die manufacturing space can be saved; and the die is convenient to transport.

Description

technical field [0001] The invention relates to the field of mold manufacturing for wind power generator blades, and is a mold capable of preparing various wind power generator blades. Background technique [0002] At present, all wind power blades in the world are produced using one mold corresponding to one size of blade. If the blade size is changed, a new mold needs to be remade. Therefore, in the process of manufacturing multi-size blades, the production space is relatively high, and a single manufacturer is very difficult. It is difficult to have enough space to meet the production of full-size blades. At the same time, with the development of wind turbines to higher power, the size of the blades is also gradually increasing. The traditional molds can only be eliminated because they do not meet the needs of the existing size, resulting in a waste of resources. Moreover, traditional molds are large in size and heavy in weight. For safety reasons, the railway and highwa...
