Abstract
The utility model relates to the field of wind turbine blades and in particular relates to an integral manufacturing mould for a root-end reinforcing layer of a wind turbine blade. The integral manufacturing mould comprises a mould and a blade upper housing without a reinforcing layer, wherein the mould is used for forming the blade; and the blade upper mould without the reinforcing layer is used for pre-curing. The integral manufacturing mould is characterized by further comprising an inner supporting frame with a notch, a vacuum bag film and a reinforcing layer, wherein the vacuum bag film and the reinforcing layer are paved on the inner supporting frame in sequence; flat seams of the cloth layer are formed in the notch of the inner supporting frame; and the inner supporting frame is hung on at the root end of the lower mould. According to the integral manufacturing mould for the root-end reinforcing layer of the wind turbine blade disclosed by the utility model, the reinforcing layers at the root ends of the upper half mould and the lower half mould of the blades are co-filled, so that the mould seams are prevented from being closed, and the strength of the root end is high.
Description
Technical field
The utility model relates to the wind power generation blade field, is specifically related to a kind of fan blade butt enhancement layer integral production technique and mould.
Background technology
The bolt that blade pass is crossed butt is connected with wheel hub, and the operating stressed strong point of blade is at butt, so the stressed maximum of butt is the highest to requirement of strength.Divide female die respectively after moulding but traditional blade production technology pattern is blade, then by matched moulds after the coating bonded adhesives, upper female die is integrated.Because adopted the secondary bonding forming, often there are the too high problems such as polishing, adhesive surface too lowly are inconvenient to bond, the extra reinforcement of bonding plane needs that need of bonding plane.The utility model makes upper and lower radical of semimodules end enhancement layer realize common perfusion by changing traditional work pattern, and it is as a whole that butt becomes, thereby avoided the matched moulds seam, just there is no traditional defective.
The utility model content
Technical purpose of the present utility model is to overcome the problems of the prior art, provides a kind of upper and lower half module butt enhancement layer of blade that makes to realize jointly pouring into, avoiding fan blade butt enhancement layer integral production technique and the mould that matched moulds stitches, butt intensity is high.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is: fan blade butt enhancement layer integral production technique comprises the steps: 1) complete laying, precuring without enhancement layer blade upper shell; 2) lower house except enhancement layer, is completed the laying of all the other layer of cloths; 3) contain on inner support frame jaggy lay vacuum bag film and water conservancy diversion material after, successively lay the enhancement layer of upper and lower mould and the enhancement layer of patrix, the carvel joint of layer of cloth stays the indentation, there in inner support frame; 4) inner support frame that step (3) is finally obtained is lifted on the counterdie butt; 5) in the indentation, there of inner support frame, the layer of cloth of enhancement layer is pressed a layer butt up; 6) matched moulds is implemented priming by vacuum.
For realizing the purpose of this utility model, another technical scheme that the utility model adopts is: fan blade butt enhancement layer integral production mould, comprise mould for blade forming, precuring and without the blade upper shell of enhancement layer, it is characterized in that: also comprise containing inner support frame jaggy, also comprise the vacuum bag film, the enhancement layer that are layed in successively on inner support frame, the carvel joint of layer of cloth stays the indentation, there in inner support frame; Inner support frame is lifted on the counterdie butt.
Aforesaid fan blade butt enhancement layer integral production mould, the blade upper shell is without enhancement layer.
The utility model prerequisite is an existing patrix housing (containing enhancement layer) of completing without the precuring of enhancement layer, counterdie is except the layer of cloth of butt enhancement layer, all the other layer of cloth normal layings, be layed on inner support frame by technological requirement according to the difference of the internal-and external diameter layer of cloth with enhancement layer, then inner support frame and cloth are lifted to the counterdie butt, lay vacuum material, realize common perfusion with counterdie after matched moulds, make the upper and lower half module butt enhancement layer of blade realize common perfusion, avoid the matched moulds seam, butt intensity is high.
Description of drawings
Fig. 1 is the schematic diagram of fan blade butt enhancement layer integral production technique of the present utility model;
Wherein, 1 mould, 2 housings without enhancement layer, 3 enhancement layers, 4 vacuum bag films, 5 inner support frames.
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.
Referring to Fig. 1, the step of manufacture craft of the present utility model is: 1) complete laying, precuring without the upper shell of enhancement layer, without the housing 2 of enhancement layer; 2) counterdie except enhancement layer 3, is completed the laying of all the other layer of cloths; 3) after laying vacuum bag film 4 and water conservancy diversion material on inner support frame 5, the layer of cloth of the enhancement layer 3 of upper and lower mould 1 to be spread, the carvel joint of layer of cloth stays in the indentation, there of inner support frame 5; 4) will lift and the counterdie butt by technological requirement with the inner support frame 5 of layer of cloth; 5) in the indentation, there of inner support frame 5, the layer of cloth of enhancement layer 3 is pressed a layer butt up; 6) matched moulds is completed all the other vacuum operations; 7) after vacuum condition meets the requirements, perfusion.
Fan blade butt enhancement layer integral production mould, comprise mould 1 for blade forming, precuring and without the blade upper shell of enhancement layer, it is characterized in that: also comprise containing inner support frame 5 jaggy, also comprise the vacuum bag film 4, the enhancement layer 3 that are layed in successively on inner support frame 5, the carvel joint of layer of cloth stays in the indentation, there of inner support frame 5; Inner support frame 5 is lifted on the counterdie butt.
The utility model prerequisite is an existing patrix housing of completing without the precuring of enhancement layer, counterdie is except the layer of cloth of butt enhancement layer, all the other layer of cloth normal layings, be layed on inner support frame by technological requirement according to the difference of the internal-and external diameter layer of cloth with enhancement layer, then inner support frame and cloth lifted to the counterdie butt, lay vacuum material, realize common perfusion with counterdie after matched moulds, make the upper and lower half module butt enhancement layer of blade realize common perfusion, avoid the matched moulds seam, butt intensity is high.
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.
