Description
Technical field
The invention belongs to technical field of composite materials, relate generally to a kind of wind power generation blade lower house and leading edge and paste the integrated method in angle.
Background technology
In the forming process of wind power generation blade, because volume own is big, and there is support member in inside, so be difficult to one-shot forming, generally be to make, pass through the mode of case bonding up and down then, make that going up lower house forms integral blade by blade being divided into lower house.For guaranteeing enough adhesive strengths, the bond area in the time of must adopting leading edge stickup angle to increase case bonding up and down.Wind power generation blade can divide following step when making, as Fig. 1:
A) upper and lower casing shop layer.This step is meant glass fabric is routed to die surface, as the reinforcing material of blade.
B) perfusion of upper and lower casing.This step is by up and down setting up vacuum system respectively on the housing mould, and the glass fibre structure of the last lower house of blade is coated in the vacuum system, utilizes atmospheric pressure, and resin is filled in the glass fabric, makes the complete sized glass fibres cloth of resin.
C) curing of upper and lower casing.This step is the heater that carries by housing mould up and down, makes resin react gradually, and viscosity becomes greatly gradually, becomes the process of solid at last.
D) the upper and lower casing demoulding is made leading edge in the leading edge of lower house and is pasted the angle.This step is meant the leading edge at lower house, makes a splicing tape, to increase the blade bond area of leading edge during case bonding up and down.
E) bonding web.This step is meant on lower house, the process of bonding internal support.
F) matched moulds.This step is meant upper and lower casing is bonded to together process.
Wind electricity blade is in the process of using, leading edge not only is subjected to the effect of various load, especially also need bear the impact of various dusts storm, corrode, so leading edge also becomes blade one of the zone of easy infringement, the bonding quality of leading edge will directly determine the life-span of blade, and the goods of leading edge own are thin, and the not enough 6mm of average thickness is as Fig. 2, the bond area deficiency, adhesive strength is low, and this will cause blade in the process of rotation, last lower house cracking, blade is directly scrapped, so, just make leading edge in the design and paste the bond area that the mode at angle increases leading edge by step d), make leading edge that enough intensity be arranged, to guarantee the service life of blade, visible leading edge is pasted the critical role of angle in whole blade manufacturing process.
Make leading edge stickup angle at present in the industry and all adopt manual pasting forming process, the manufacturing process of this technology can be divided into following a few step:
The leading edge flange of cleaning blade lower house mould, convenient leading edge stickup angle mould tool, the lower house goods leading edge that polishing has been solidified of placing in this position.This step mainly be since lower house in forming process, the out-of-flatness of goods leading edge is so need the irregular part of polishing lower house leading edge.
Leading edge is installed pastes angle mould tool (upper and lower casing and leading edge are pasted the angle and had independently mould respectively).This step need be adjusted the gap between leading edge stickup angle mould tool and the lower house mould leading edge, and the angle of pitching.
Hand is stuck with paste.This step is that the resin that will mix rolls or brush by hair, be coated on the glass fabric uniformly, make its complete sized glass fibres cloth, and then will soak into that good glass fabric is layered on that leading edge is pasted the profile of angle mould tool and the lower house leading edge of having solidified on, during laying, half of the glass cloth width of Jin Runing laid on the profile of leading edge stickup angle mould tool again fully, and second half of width is laid on the lower house leading edge of having solidified.The bubble that uses mao glass cloth that rolls infiltration fully and leading edge to paste between the angle mould tool is at last driven out of.Every shop layer of glass cloth, said process need repeat once.
Cure and demold.The purpose of solidifying is to make leading edge paste shop, angle layer and lower house leading edge to reach firm bonding.After the demoulding such as is meant at resin solidification, sloughs leading edge and paste the angle mould tool.
The polishing leading edge is pasted the angle.This step is to cut edge in the leading edge stickup angle that will make, to reach suitable bond area.
Above-mentioned technology is called hand and sticks with paste technology, complicated operating process, efficient is lower, and operating environment is poor, and because manual unstability, cause the number of times of doing over again more, and manual pasting forming process is influenced by environmental temperature, especially the temperature difference in summer, winter and daytime, the temperature difference at night, the demould time that makes leading edge paste the angle is difficult to stablize, and causes quality of item also variant.
Summary of the invention
The present invention is in order to solve the problems in the hand paste technology, propose a kind of wind power generation blade lower house and leading edge and paste the integrated method in angle, not only improve the bonding quality of leading edge, and save the time that independent making leading edge is pasted the angle and waited for its curing, improve operating environment, enhance productivity.
A kind of wind power generation blade lower house that the present invention proposes is pasted the integrated method in angle with leading edge, comprises that leading edge pastes that the angle mould tool is made, leading edge is pasted angle mould tool and blade lower house mould fixes and the one form of leading edge stickup angle and blade lower house;
Concrete grammar of the present invention is:
The making that the used leading edge of one form is pasted the angle mould tool;
Under the vacant state of upper and lower shell mould of blade, carry out leading edge and paste the making of angle mould tool; Described leading edge is pasted the angle mould tool and is divided two parts to make, paste the bottom surface of angle mould tool in the lower house mould leading edge flange production leading edge of blade, paste the profile of angle mould tool in the upper shell mould leading edge flange production leading edge of blade, by the matched moulds of housing mould about the blade, two parts of the leading edge of above-mentioned making being pasted the angle mould tool are bonding again; Concrete manufacturing process can be divided into following step;
