Description

A kind of blade of wind-driven generator manufacturing method based on 3D printing technique
Technical field
The present invention relates to the technical fields of renewable energy blade of wind-driven generator manufacture, refer in particular to one kind and are beaten based on 3D The blade of wind-driven generator manufacturing method of print technology.
Background technique
Known in the industry, blade makees the core component of wind-driven generator, and design and manufacture are directly related to system structure safety And unit generation performance.Composite material is made due to the advantages such as high specific strength specific stiffness and superior corrosion-resistant anti-fatigue performance Its large-scale application in blade design manufacture.Traditional blade design manufacturing method requires first to manufacture formpiston, and then formpiston is used In manufacture blade production mold.Manufacture mold time intensive in vane manufacturing process, the process of labor intensive, it usually needs Time more than half a year.With blade enlargement, mold is manufactured as a difficult point.Mold weighs tens tons, and the manufacturing cycle is long, Fabrication tolerance is difficult to control.Manufacturing process is the key link of blade, and the manufacture of blade mostly uses vacuum infusion molding, and vacuum fills Injection formation technology is directly to be laid in fibre reinforced materials on mold, is put on one layer of fiber cloth upper berth release cloth, release cloth One layer of grooves are set, vacuum diaphragm environmental sealing is then used;Glue-feeder is opened after sealing system reaches certain vacuum degree, is set Rouge enters whole system by glue inlet tube, and diversion pipe guides resin flowing, removes release cloth after solidification, obtains compactness height containing glue Measure low structure laying.Vane manufacturing whole flow process, the test period is long, at high cost, and since resin molding process not exclusively may be used So as to cause blade construction performance discreteness big, vane manufacturing quality conformance is low for control, for the offer of rigidity of structure intensity Safety coefficient be unfavorable for carrying out blade loss of weight off field in the city of high competition to further reduce the cost greatly.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, propose a kind of feasible wind based on 3D printing technique Power generator blade manufacture method can significantly improve blade of wind-driven generator and (be manufactured by composite material) in Design and manufacturing process Period is long, the disadvantages such as process is complicated, at high cost, manufacturing quality consistency is low.
To achieve the above object, a kind of technical solution provided by the present invention are as follows: wind-power electricity generation based on 3D printing technique Machine blade manufacture method, comprising the following steps:
1) mold 3D printing: exporting mold three-dimensional CAD figure according to designed blade profile, then according to three-dimensional CAD model into The 3D printing of row mold;Wherein, if the unitary mould size of large-scale blade is more than the stamp with the size of 3D printer, in 3D printer In the case where can not disposably printing, assembled after the unitary mould of large-scale blade need to be split again to modularization printing;
2) each component 3D printing of blade: the fused glass pellet FDM technique based on 3D printing technique checks safety in structure Under the premise of 3D printing carried out to blade in order to guarantee the feasibility of 3D printing mainly divide entire blade to PS face-piece body, the face SS Three parts of shell and web also include other associated components certainly, including cover plate for manhole, lightning conductor and bracket and blade root connect Connecting bolt, under the control of the computer, the movement mechanism of print head is according to cross section profile and laying filling information, according to setting path Print head movement is driven, composite material constantly squeezes out accumulation from nozzle and forms single layer entity, by PS face-piece body, the SS of blade Face-piece body, web and other associated components print, and realize the full 3D printing of blade;Wherein, the PS face-piece body includes the face PS Rear core material, inside and outside covering covering and rear beam in face of spar cap, PS, the SS face-piece body include rear in face of the face SS spar cap, SS Core material, the inside and outside covering covering in the face SS and the face SS rear beam;
3) PS face-piece body, SS face-piece body, web and other associated components blade assembling: are subjected to group using technique for sticking Dress.
Further, the FDM technique is melted inside 3D printing head using resin and continuous fiber as raw material, real It now prepares moulding integrated.
Compared with prior art, the present invention have the following advantages that with the utility model has the advantages that
1, early period of the invention uses 3D printing technique for mold, substantially reduces die manufacturing cycle.
2, the present invention can significantly improve blade forming technique by 3D printing technique, and can overcome priming by vacuum The disadvantages of period is long, structural behaviour discreteness is big, gives full play to that the 3D printing period is short, manufacture material is abundant and can manufacture complexity The advantages such as shape, for more reasonably efficiently manufacture blade provides foundation.
3,3D printing is as a kind of increases material manufacturing technology, and priming by vacuum is to subtract material manufacture, the material of priming by vacuum removal It is difficult to degrade, compares the latter, the present invention also protects environment while shortening the development cycle.
