Technical field:
The present invention relates to a kind of fan blade and manufacture method thereof, especially relate to a kind of air-cooled fan blade and manufacture method thereof.
Background technique:
Blade is the most basic and most important parts in the air cooling blower fan, and its good design, reliable quality and superior performance are the deciding factors that guarantees the normal stable operation of air cooling blower fan.Rugged environment and ceaselessly running for a long time have the requirement of blade: light specific gravity and have best fatigue strength and mechanical property, can stand exceedingly odious condition and the tests of load at random such as storm wind.Relatively large blade generally adopts the hybrid composite of glass fibre reinforced plastics or carbon fiber and glass fibre, and resin matrix is based on epoxy.At present, the air-cooled fan blade of main flow is a fiberglass blade, and generally at blade surface coating, but China does not still have the glass fiber reinforced plastic surface coating of corrosion resistant, good weatherability at present, still adopt common nitro spraying lacquer at blade surface, in the steam ambient of water that is corrosive, generally can only turn round 5000 hours, the surface coating fluffing that promptly comes off influences working life of blade.
The manufacturing firm of present domestic fan blade adopts the wet method hand to stick with paste technology owing to be subjected to the influence of aspects such as market, technology, material and fund mostly, and isothermal curing is realized producing in batches.Its wet method hand paste technology is simple relatively, does not need the pressurization device of heating, and does not need tooling device.But when shortcomings such as this explained hereafter efficient is low, labor intensity big, labour health condition is poor, quality of product is wayward, stability is not high, the product mechanical property is lower, this technology can only be used to produce length of blade usually than short and small lot batch manufacture.But for large-scale air-cooled fan blade, because the blade build is bigger, manual pasting forming process can't be competent at.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency, provide a kind of in light weight, intensity is high, anti-natural wind ability is strong, the air-cooled fan blade and the manufacture method thereof of long service life.
The present invention is achieved through the following technical solutions: a kind of air-cooled fan blade, be multi-layer structure, and its multi-layer structure is followed successively by lower protective layer, following layer of cloth, physical layer, middle layer of cloth, bond coat, goes up layer of cloth, goes up protective layer.Upward protective layer and lower protective layer are that the thick nanometer weatherable materials of 0.5mm is made, and product anti-aging time limit in the environment of 40 degrees below zero Celsius 120 degree extremely Celsius was reached more than 30 years; Its lower floor's cloth, middle layer cloth, upper strata cloth are the thick glass fiber cloth of 0.1mm; This physical layer is the streamlined and inner netted muscle frame that is provided with, and this muscle frame is that netted alloy fiber material is made, and have high strength toughness, and anti-natural wind ability is strong; This bond coat is that three layers virtue, platinum fiber and polyester are formed and are added with noble metal and overlap and form, and this noble metal be a silver, and it is in light weight, intensity is high thereby make, and the polyester in described physical layer and bond coat is employing import high strength unsaturated resin.
A kind of manufacture method of air-cooled fan blade comprises the steps:
(A) preparation of mould: shape and size according to air-cooled fan blade are prepared corresponding mould;
(B) in mould, lay lower protective layer, following layer of cloth, and laying the alloy fiber frame on the layer of cloth down, on the alloy fiber frame, inject polyester again and soak into, layer of cloth on polyester, laying, and on middle layer of cloth, be equipped with bond coat, lay layer of cloth on the bond coat, laying protective layer on the last layer of cloth;
(C) envelope film emptying: film cloth is placed on the mould, and makes mould and film cloth bonding, utilize vacuum pump deaeration 5-15 minutes, make it reach vacuum;
(D) mold pressing thermosetting: with mold heated to 60-80 degree, and be pressurised into 45-55 tons pressure on die cover by hydraulic press with electrically heated mode, the time of pressing solidly is 1.5-2.5 hours;
(E) thermostatic curing: at mould is to place 3.5-4.5 hours in 40-50 constant temperature of spending;
(F) demoulding shaping: with blade and mold separation, and begin finished edge, make its smooth surface, smooth from lifting the position;
Further, in described step (C), envelope film emptying time is 10 minutes; In described step (D), with mold heated to 70 degree, and be pressurised into 50 tons pressure on die cover with electrically heated mode by hydraulic press, the time of pressing solidly is 2 hours; In described step (E), be to place 4 hours in 45 constant temperature of spending at mould.
The present invention compared with prior art has the following advantages: in light weight, intensity is high, anti-natural wind ability is strong, long service life, the bearing capacity of blade of having improved, its manufacture method is easy, because under vacuum pressure, make the infiltration step more perfect, given full play to the effect of material, guaranteed quality of product, improved manufacturing efficiency, reduced the labour force, economized on the use of funds, can be used for producing in enormous quantities.
