Abstract
The utility model relates to the field of wind turbine blades and in particular relates to a root-end refining mould for wind turbine blades. The root-end refining mould is characterized by comprising an upper mould, a lower mould and refining flanges, wherein the upper mould and the lower mould are used for forming blades; the refining flanges are arranged at the root ends of the upper mould and the lower mould; the refining flanges are divided into upper mould flanges and lower mould flanges along mould parting lines of the upper mould and the lower mould; the upper mould flanges are fixed on the upper mould; the lower mould flanges are fixed on the lower mould by a fixing device in a detachable manner; cloth layers at the root ends of the blades are paved adjacently to the flanges; the blades are formed among the blades; and the lower mould flanges are separated from the lower mould by opening the lower mould flange fixing device. The root-end refining mould for the wind turbine blades disclosed by the utility model is used for solving the problem that the flanges are complex in machining; during a cloth layer paving process, the cloth layers at the root ends are firmly leant against the refined flanges; and the lower mould flanges are de-molded after the blades are formed, so that the blades are smoothly de-molded.
Description
Technical field
The utility model relates to the wind power generation blade field, is specifically related to the refining mould of a kind of fan blade butt.
Background technology
Wind-power electricity generation market has now entered the cruel market competition stage through in a few years high speed development.Blade is faced with equally the market price and day by day drops as the important component part of whole blower fan, and the predicament of raw material, labor cost rise.Lean production under such overall situation, to reduce unnecessary waste imperative.
The plane treatment that blade is connected with the complete machine wheel hub, existing have a dual mode, and a kind of mode of built-in turnbuckle when layer of cloth is laid, is come control plane by the butt locating flange, but it is because will play the effect of bolt, therefore processed complex.Another kind is to cut out a plane by puncher at blade root after blade forming, so just need to layer of cloth need to be grown 3-5cm at butt when the blade laying, causes waste.
Butt process for refining of the present utility model is that the mode with pre-buried mode and punching unites two into one, and the complexity of the butt locating flange of both having avoided has avoided again reserving for cut out the plane afterwards the waste of layer of cloth.
The utility model content
Technical purpose of the present utility model is to overcome the problems of the prior art, provides a kind of refining flange of butt installation at upper/lower die, blade root layer of cloth to process relatively simply, save the refining mould of fan blade butt of cloth layer material near refining flange, refining flange.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is: the fan blade butt is made with extra care mould, it is characterized in that: comprise upper and lower mould for the moulding blade, be installed on the refining flange of upper and lower mould butt, refining flange is divided into upper and lower modulus method orchid along the die parting line of upper and lower mould, the patrix flange is fixed on mold, the counterdie flange removably is fixed on bed die by fixture, and the blade root layer of cloth is laid near flange; Make the counterdie flange break away from bed die by opening the counterdie flange fixing device.
Aforesaid fan blade butt is made with extra care mould, flange install and during the demoulding and mould be an acute angle.
Aforesaid fan blade butt is made with extra care mould, but described fixture is the fixed hinge of folding.
The utility model adopts refining flange at blade root, and blade root layer of cloth direct adjacent flange when laying is laid, and the blade root after moulding need not to repair type, and length of blade is design length; Because of the reason of demoulding angle, the patrix flange design is fixed, but the counterdie flange passes through the fixed hinge folding, and when laying layer of cloth, the butt layer of cloth makes the demoulding of counterdie flange near refining flange after blade forming, make the smooth demoulding of blade.
Description of drawings
Fig. 1 is the structure chart of the refining mould of fan blade butt of the present utility model;
Fig. 2 is the sectional view of mould of the present utility model;
Wherein, 1 mould, 2 refining flanges, 3 fixtures, 4 flange setting angles, 5 die parting lines.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described in detail: the present embodiment is to implement under prerequisite in technical solutions of the utility model; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As depicted in figs. 1 and 2, fan blade butt process for refining comprises the steps: 1) at the butt of the upper and lower mould 1 that is used for the moulding blade, refining flange 2 is installed; 2) refining flange 2 is divided into upper and lower modulus method orchid along the die parting line 5 of upper and lower mould 1, and the patrix flange is fixed on mold, and the counterdie flange removably is fixed on bed die by fixture 3; When 3) laying layer of cloth, the counterdie flange is fixed on bed die, and the blade root layer of cloth is laid near flange; 4) after blade curing is completed, open upper die and lower die flange fixing device 3, the counterdie flange breaks away from bed die, the blade demoulding.Flange install and during the demoulding and mould 1 be an acute angle, namely the flange setting angle 4.But fixture 3 is the fixed hinge of folding.Detailed process is: according to blade physical length and die angle, manufacturing flange is installed; The patrix flange is fixed on mould 1, and the counterdie flange is arranged on counterdie by fixed hinge opening or closing; Laying modulus method orchid is at present closed, and the butt layer of cloth is laid near flange; After blade curing is completed, open the upper die and lower die hinge, deviate from blade.
According to Fig. 1 and Fig. 2, the fan blade butt is made with extra care mould, it is characterized in that: comprise the upper and lower mould 1 for the moulding blade, be installed on the refining flange 2 of upper and lower mould 1 butt, refining flange 2 is divided into upper and lower modulus method orchid along the die parting line 5 of upper and lower mould 1, the patrix flange is fixed on mold, and the counterdie flange removably is fixed on bed die by fixture 3, and the blade root layer of cloth is laid near flange; Make the counterdie flange break away from bed die by opening counterdie flange fixing device 3.Flange install and during the demoulding and mould be an acute angle, namely the flange setting angle 4.But fixture 3 is the fixed hinge of folding.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
