Abstract
The invention discloses an integrated filling and forming process for a single shearing rib of a fan blade. According to the integrated filling and forming process for the single shearing rib of the fan blade, work efficiency during preparing the fan blade is raised. The process is specifically characterized in that: only an end of the shearing rib is fixed through adding an adhesive, the other end of the shearing rib is fixed through biaxial glass fiber cloth, such that the use amount of the adhesive is reduced; in addition, the shearing rib is placed in a center position of a main spar cap, such that the shearing rib can be ensured to be positioned exactly, and the offset phenomenon is not generated during a moulding process.
Description
Technical field
The present invention relates to a kind of fan blade one pouring and forming process, particularly relate to a kind of fan blade monolithic shearing ribs one pouring and forming process.
Background technology
The fan blade that is used for wind-driven generator is the shell structure that a kind of composite is made, and every generator generally has many blades.In the prior art, the fan blade mould before matched moulds need applying glue on the end face of upper and lower mould shearing ribs with the girder cap that shearing ribs is bonded to the blade inwall on.But, in order to guarantee the bonding thickness of bonding region, note the use of adhesive, if adhesive easily causes the phenomenon of shearing ribs starved with having lacked, thereby cause inefficiency, the adhesive use amount is big.In addition, in the prior art, the precision when shearing ribs is located is relatively poor, and shift phenomenon easily takes place in the matched moulds process.
In sum, problem demanding prompt solution is, need to existing fan blade particularly the manufacturing process of fan blade monolithic shearing ribs improve, to reduce the use amount of shearing ribs being carried out adhesive when bonding, improve the positioning accuracy of shearing ribs.
Summary of the invention
Technical problem to be solved by this invention is, a kind of fan blade monolithic shearing ribs one pouring and forming process is provided, it need use a large amount of adhesives when having solved in the prior art bonding shearing ribs, easily produces starved behind matched moulds, and the relatively poor problem of precision when shearing ribs located.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of fan blade monolithic shearing ribs one pouring and forming process, and this technology may further comprise the steps:
A. in the upper die and lower die of fan blade mould, lay working face housing and pneumatic face-piece body respectively;
B. shearing ribs being carried out precuring handles;
C. in the upper die and lower die of fan blade mould, lay girder cap, core, second layer housing successively, one end of the described shearing ribs that will handle through precuring is installed on the center of counterdie girder cap to form stiff end, makes the center line of shearing ribs and the central lines of girder cap up and down;
D. the stiff end that is installed in the shearing ribs on described counterdie girder cap or the patrix girder cap is carried out tool locating;
E. utilize twin shaft to glass cloth the stiff end of described shearing ribs to be fixed, glass cloth must be fitted with shearing ribs and girder cap;
F. after finish described shearing ribs location, remove frock, coat adhesive, blade counterdie and patrix are carried out matched moulds, finish glued curing at the not stiff end of described shearing ribs.
In the described fan blade monolithic shearing ribs one pouring and forming process, the thickness of described shearing ribs is 60cm.
In the described step (e) of described fan blade monolithic shearing ribs one pouring and forming process, it is that the twin shaft of 100mm is fixed it to glass cloth that one deck width is respectively adopted in the stiff end both sides of described shearing ribs.
In the described step (f) of described fan blade monolithic shearing ribs one pouring and forming process, finish described shearing ribs location, remove after the frock, on the blade shell inwall, lay barrier film with holes, water conservancy diversion net successively, treat that pressure is evacuated to 100mbar perfusion resin when following to form vacuum systems, after perfusion is finished, heating mould to 75 ℃ is incubated and stops heating after 4 hours, coats adhesive at the not stiff end of described shearing ribs, blade counterdie and patrix are carried out matched moulds, finish glued curing.
Advantage of the present invention is, disclosed fan blade monolithic shearing ribs one pouring and forming process has improved the operating efficiency when making fan blade, particularly, this technology only needs to fix in an end applying glue of shearing ribs, the other end is then fixed to glass cloth by twin shaft, thereby has reduced the use amount of adhesive.In addition, this technology is placed on girder cap center with shearing ribs can guarantee the shearing ribs accurate positioning, and shift phenomenon does not take place in the matched moulds process.
