Description
Technical field
The present invention relates to wind electricity blade production technical fields, and in particular to bonding angle is prefabricated and integral pouring and forming process.
Background technology
In existing wind electricity blade molding technology thereof, the molding mode to front and rear edges bonding angle is：In covering forming process
In, trailing edge bonding angle layer of cloth is laid with together with covering layer of cloth, relies on bonding angle tool locating layer of cloth, control glue-line, bonding angle cloth
Layer form together with covering layer of cloth.This moulding process has the disadvantage that：（1）During laying, because trailing edge is compared with leading edge
Radian is bigger than normal, and trailing edge bonding angle frock radian is bigger than normal, and layer of cloth is not easy sturdy with frock, and the bad adjustment of layer of cloth wastes a large amount of man-hours；
（2）Because trailing edge bonding angular breadth is wide compared with glue, forming process needs accommodating tool in addition, and vacuum diaphragm bad adjustment during bag vacuum easily goes out
Existing vacuum diaphragm is hanging, and vacuum diaphragm is once hanging, and easily being taken out in filling process quick-fried causes gas leakage；（3）In filling process, because of trailing edge
There is uniaxially layer of cloth, gluing is slow, also needs perfusion trailing edge bonding angle, causes perfusion resin demand bigger than normal；And trailing edge walks glue and is not easy to see
It examines；（4）If trailing edge bonding angle forming frock uses formpiston, easily at frock edge, uniaxially layer of cloth region forms step, repairs into
This height；（5）After shaping, easily there is the defects of fold, step in bonding angle, and maintenance time is long, and the blade production cycle lengthens；And due to
Trailing edge cavity limits, and the defect is not easy to identify, therefore there are larger quality risks；（6）After covering cures, the work of bonding angle
Dress, auxiliary material cleaning difficulty are big, the waste plenty of time.
The content of the invention
The present invention in order to more than solving the technical issues of, provide that bonding angle is prefabricated and integral pouring and forming process.
To solve the above problems, bonding angle of the present invention is prefabricated and integral pouring and forming process, comprise the steps of：
A. bonding angle Mold Making：Bonding corner structure is kept, in band after bonding angle simulation layer of cloth is divided into two according to molding seam
The windward side of covering die and leeward are laid with respectively and form；Scraping thickness on leeward bonding angle simulation layer of cloth is
2.0-4.0mm, wide 30-50mm triangle glue-type after, windward side is molded and is bonded, is demoulded after cured up to formpiston master mold；
Using angle grinder, peak steel knife that deburred on the inside of the formpiston master mold is clean, coated with releasing agent is laid with perforated membrane, cuts glass
Cloth form is demoulded after being heating and curing up to bonding angle prefabricated mould；
B. bonding angle is prefabricated：Bonding angle is pre-formed in advance as a component using the bonding angle prefabricated mould；Shaping
When, it is laid with using the forming surface of outer surface as the bonding angle inner cavity of the bonding angle prefabricated mould, is carried out after laying
Perfusion；It after the completion of perfusion, wraps three layers of vacuum and is covered using insulation quilt, place air-heater in blade root and blade tip position, institute is set
The temperature of air-heater is stated as 75-85 DEG C, 5.6-6.8h of continuous heating, after heating terminates and confirms and be fully cured, sampling and measuring
Tg values when Tg >=60 DEG C can remove auxiliary material, the surface temperature of layer of cloth at vertical rib are measured using temperature-measuring gun, when surface temperature≤40
DEG C when can demould, directly gained bonding angle prefabricated component is positioned over after the demoulding and is loaded onto for use with type storing name；
C. covering forming：During blade covering forming, the stage of bonding angle need to be made in former technique, imitates girder air guide system
