Abstract
This invention discloses vacuum assisted pouring method for large-scale wind mill blade and is characterized in that the steps are: 1. prepare one layer hard mould board as mould; 2. lay the fiber reinforced material on mould board, coat with vacuum bag placed hose inlet and vacuum pump interface, and seal around; 3. link the vacuum bag and pump; 4. when sealing the mould and ensuring no air leakage, start the pump to vacuumize till some vacuum degree, inject resin, solidify and form. The benefit result of the invention comprises to increase production efficiency, decrease labor intensity, stabilize product quality and improve mechanical property.
Description
Technical field
The present invention relates to use vacuum auxiliary pouring technology moulding covering and enhancement Layer structure, particularly a kind of large scale wind power machine blade vacuum auxiliary pouring method in the production process of the large scale wind power machine blade made by fiberglass.
Background technology
Vacuum auxiliary pouring and molding technology is a kind of improved RTM technology that grows up recent years.It originates from people such as the L.JamesLee of Ohio, USA university, the vacuum auxiliary pouring technology is that applied film coats chunk, the application vavuum pump vacuumizes, medium guiding by means of the high permeability that is layered on the structure sheaf surface, resin is injected into a kind of technology in the structure shop layer, the large thick-wall goods that are used for the forming shape complexity more, the large-scale pneumatic equipment blades made bodily form is huge, use traditional manual pasting forming process and be difficult to implement, moreover that hand pasting forming has production efficiency is low, labour intensity is big, labour health condition is poor, product quality is wayward, and stability is not high, the shortcoming that the product mechanical property is lower.
Summary of the invention
The objective of the invention is to use the shortcoming of traditional hand pasting forming, a kind of large scale wind power machine blade vacuum auxiliary pouring method is provided in order to overcome large-scale pneumatic equipment blades made.Technical scheme of the present invention is: a kind of large scale wind power machine blade vacuum auxiliary pouring method is characterized in that the step of method is: 1, make one deck hard template as mould; 2, fibre reinforced materials is laid on the template, coat with the vacuum bag that is equipped with glue inlet tube inlet and vavuum pump interface, and around the sealing; 3, be connected with vavuum pump by the vacuum bag interface; 4, intact when mould sealing, confirms no air leakage after, start vavuum pump and vacuumize, reach the certain vacuum degree after, begin to inject resin, curing molding.
The described fibre reinforced materials that is laid on the template constitutes by being followed successively by mode structure shop layer, release cloth and flow-guiding cloth from top to bottom.
Be equipped with mozzle above the described flow-guiding cloth, mozzle is connected with glue inlet tube.
The invention has the beneficial effects as follows: make large scale wind power machine blade vacuum auxiliary pouring method, have production efficiency and improve, labour intensity reduces, the product quality stable performance, and mechanical property is than advantages such as height.
Description of drawings
Fig. 1 is a large scale wind power machine blade vacuum auxiliary pouring system schematic diagram;
Fig. 2 is a large scale wind power machine blade vacuum auxiliary pouring process chart.
The specific embodiment
A kind of large scale wind power machine blade vacuum auxiliary pouring method, resin perfusion system is characterized in that by shown in Figure 1 the step of method is: 1, make one deck hard template as mould 6; 2, fibre reinforced materials is laid on the template, coat with the vacuum bag 1 that is equipped with glue inlet tube 3 inlets and vavuum pump interface 7, and around the sealing; 3, be connected with vavuum pump by vacuum bag interface 7; 4, intact when mould sealing, confirms no air leakage after, start vavuum pump and vacuumize, reach the certain vacuum degree after, begin from glue-feeder 2 injection resins, curing molding.
The described fibre reinforced materials that is laid on the template constitutes by being followed successively by structure shop layer 8, release cloth 5 and flow-guiding cloth 4 from top to bottom.The fabric of the low porosity that release cloth 5 is easily peeled off for one deck, flow-guiding cloth 4 is the medium of high permeability, be equipped with mozzle 9 above the described flow-guiding cloth 4, mozzle 9 is connected with glue inlet tube 3, and resin enters whole system by the glue-feeder 2 of glue inlet tube 3, by the principal direction of mozzle guiding resin flows, the resin distribution that makes flow-guiding cloth 4 arrives the every nook and cranny of shop layer, peel off release cloth 5 after the curing, thereby obtain the packing height, the structure shop layer 8 that gel content is low.Concrete technological process is by shown in Figure 2.
