Manufacturing mold of wind power blade and flange of manufacturing mold

Abstract

The invention discloses a manufacturing mold of a wind power blade and a flange of the manufacturing mold. The manufacturing mold of the wind power blade comprises an upper mold body and a lower moldbody which are arranged to be opposite mutually; the upper mold body and the lower mold body comprise an upper metal steel frame, a lower metal steel frame and an upper blade mold body and a lower blade mold body which are arranged on the upper and the lower metal steel frames respectively; the manufacturing mold of the wind power blade is characterized by further comprising the flange; the flangecomprises a semi-circular upper flange body and a semi-circular lower flange body which are used for being connected with the upper blade mold body and the lower blade mold body, heating modules arearranged on the upper flange body and the lower flange body respectively, and each heating module comprises a heat conduction part being at least partially pre-buried in the upper flange body and thelower flange body; a plurality of bolt holes are formed in each of the upper flange body and the lower flange body, pre-buried bolt sleeves are arranged on the upper blade mold body and the lower blade mold body respectively, and after the upper mold body and the lower mold body are assembled, the bolt holes of the upper flange body and the lower flange body are fixed with the pre-buried bolt sleeves arranged on the upper blade mold body and the lower blade mold body in an one-by-one corresponding mode; and the flange heats the upper blade mold body and the lower blade mold body through the heat conduction parts. The blade root curing process operation is outstandingly simplified, and the curing efficiency is improved.

Description

technical field [0001] The invention relates to a wind power blade, in particular to a mold for manufacturing a wind power blade and a flange thereof. Background technique [0002] With the increasingly serious energy crisis, wind power has become the direction of electric power development in recent years with its characteristics of huge capacity, no pollution, and resource regeneration. As a key component of wind turbines, the longest megawatt-level wind power blade has reached more than 60M. The main body is made of lightweight, high-strength sandwich composite materials, and the blade shape is a shear rib support box structure. The current mainstream manufacturing process Mold vacuum infusion preform and mold clamping glued post curing. As a key component of wind turbines, wind turbine blades' operation stability will directly affect the normal operation of wind turbines. The design life of wind turbine blades is mostly ten or even twenty years. How to ensure that ...
