Type has had tens kinds.Its wind field covered is from surpassing a class to weak four classes.
Wind electricity blade is a vitals of wind power generating set, and the length of current blade is more and more longer, and the moment of flexure of root is also got over
Coming the biggest, root of blade the most more and more have employed pre-embedded bolt set technology.
But the pre-embedded bolt of prior art set for common circle, during preparation when priming by vacuum root of blade, circular pre-buried
Four angles up and down of bolt sleeve easily form buildup of resin, and this buildup of resin is very harmful for the operation of blade,
In the case of blade high speed rotating, it is likely to result in bolt sleeve from root of blade laying, the dangerous situation such as extracts.
Therefore, long in order to meet length, the stable safe handling demand of the fan blade that Generation Rate is big, necessary in existing skill
On the basis of art, to be firmly bonded degree high for design research and development one, it is ensured that fan blade stablize safe handling its conveniently
There is fan blade of square pre-embedded bolt set and preparation method thereof.
Summary of the invention
Goal of the invention: the invention aims to solve the deficiencies in the prior art, it is provided that a kind of adhesive property is reliable, connects strong
Degree height, production efficiency is high, especially can solve the blower fan with square pre-embedded bolt set of prior art bolt sleeve surrounding richness glue problem
The preparation method of root of blade.It is long that the present invention can meet root of fan blade length, bears the fan blade requirement that load is bigger.
Technical scheme: in order to realize the purpose of the present invention, the technical solution used in the present invention is:
The preparation method of a kind of root of fan blade with square pre-embedded bolt set, it is characterised in that comprise the following steps:
A, the preparation of square bolt sleeve:
The bar of selection circle or the metal material of square cross section are as processing base material, by circular or square processing base material
Heating, is then placed in having in the mould of the anti-profile of square bolt sleeve, applies external applied load pressure, and being processed into surface has laterally or spiral shell
Stricture of vagina is to the square bolt sleeve of groove, and then the surface of square shaped bolt sleeve carries out blasting treatment, prepares square bolt sleeve；
B, in the surface groove of square bolt sleeve be wound around roving；
C, then root at blade mold install one for positioning the rigidity flange of square bolt sleeve；
