Description

A kind of preparation method of wind-powered blade mold
Technical field
The present invention relates to a kind of preparation method of shaping dies, be particularly suitable for the preparation method of the shaping dies of fiber-reinforced resin matrix compound material members such as large-scale wind electricity blade.
Background technology
Mould is a key of making wind power generation blade and other large-scale resin base fiber reinforced composite material members, and the stability of the quality of die quality and mould itself directly has influence on production efficiency, product quality and the production cost of these composite elements.
The Mold Making of conventional composite materials blade of wind-driven generator at first is to make master mold, and promptly the product full pattern adopts hand paste technology to turn on master mold then and makes mould.
The master mold of making fiber reinforced plastic mold at present is many to be made with base materials such as gypsum, timber, cement, paraffin, the master mold that these materials are made often lower, the poor dimensional stability of dimensional accuracy, surface quality poor, easily produce pore and crackle, flatness is poor, fabrication cycle is long, mould is fragile, and service life is short.
The main feature that hand is stuck with paste technology is that manual operations, die sinking moulding, production efficiency are low, and the production cycle is long and the resin solidification degree is often on the low side, is fit to the production that product lot quantity is less, quality uniformity requires low and composite product.Therefore the major defect of hand paste explained hereafter fan blade is that product quality is bigger to workman's skilled operation degree and environmental condition dependence, and production efficiency is low, and the product quality fluctuation is bigger, and the static and dynamic equilibrium of product guarantees that property is poor, and percent defective is higher.Particularly to pneumatic external form of high performance complexity and sandwich structure blade, also often need secondary operations such as bonding, technique for sticking needs bonding platform or type frame to guarantee the applying of bonding plane, and production technology is complicated and difficult more.The blade mold that hand is stuck with paste the technology manufacturing in use goes wrong often because hand pastes the fiber in the fabrication technique process and the resin rate of change is big, fiber/resin is soaked into bad and solidify crackle and the cracking that causes such as incomplete.In addition, hand is stuck with paste technology toward the release of contact meeting with a large amount of harmful substances and solvent, and operator's health is worked the mischief, and environment is polluted.
This traditional die manufacturing cost height, the cycle is long, simultaneously because the size of mould is difficult to transportation and preservation greatly.In addition, the life-span of such mould is shorter usually.
Summary of the invention
Technical problem to be solved by this invention is: the wind-powered blade mold preparation method that a kind of low noise, energy-conservation, pollution-free, operating numerical control automation are provided.
Technical scheme of the present invention is: a kind of preparation method of wind-powered blade mold, comprise the steps,
(1), die surface cut apart with modularization handle according to client's blade design data;
(2) utilize the die surface of the gradual metal blank former of single-point produce modular, boring, cutting;
(3) utilize laser scanner to detect forming accuracy;
(4) the pedestal keel frame of making and assembling mould;
(5) the contraposition welding of modularization surface metal sheet on pedestal, thermocouple is reinforced and installed to the sheet material backboard;
The accuracy detection on the wind electricity blade unitary mould surface that (6) welded and installed is good, polishing, polishing;
(7) heating, the installation of temperature control systems such as cooling in wind-powered blade mold, debugging.
Beneficial effect: the present invention utilizes computer numerical control technology, utilize general pressure head, the used metal blank of molding is carried out the add up technology of plastic deformation of part, with special-purpose single-point progressive molding technology is core, make the Plastic Forming of die surface sheet metal, again through cutting edge, boring, welding, following process such as sanding and polishing are done pedestal with the support keel framework that sheet metal is done, and the mould back side makes and strengthens resin-based fibrous composite layer, install heating, the required temperature control system of cooling additional, just can finish the large-scale particular manufacturing craft that the wind-powered electricity generation composite material blade is used.
Make owing to realize the numerical control die surface, greatly improved wind-powered blade mold especially the making precision and the smoothness of die surface curved surface.The fabrication cycle and the financial cost of this quasi-tradition large-scale composite material mould of wind electricity blade have been reduced, increased the service life of mould, also improved simultaneously and utilized this new technology to make blade end product quality and static and dynamic equilibrium assurance property that mould is made, greatly reduce the percent defective that blade mold and finished product are produced, improved production efficiency.Reduce the fabrication cycle and the cost of mould, increase the service life of mould, improve blade mold especially the making precision and the surface quality of die surface.
Realize numerically controlled automatic, few peopleization has reduced traditional handworker greatly, so no longer need to depend on handworker's skilled operation degree and environmental condition, has shortened the production cycle, has improved operating efficiency.In addition, the temperature control system that the mould back side has installed the cooling of can heating additional can pass through temperature detect switch (TDS), and needed temperature in the arbitrarily balanced control composite production is effectively controlled hardening time of resin.
The mould manufacturing method that the present invention relates to does not need to make traditional master mold, and the metal sheet metal of mould then, constitutes an integral body by welding and other methods of attachment and metal framework directly by numerical control Asymptotical Method Accurate Shaping.
Mould involved in the present invention can be used for the fiber-reinforced resin matrix compound material member that traditional hand paste method is shaped, the fiber-reinforced resin matrix compound material member that the vacuum inhalation is shaped, and resin transfer modeling method fiber-reinforced resin matrix compound material member.
