Abstract
The invention relates to the field of wind power generation blades, in particular to an integral manufacturing process for an enhancement layer at the root end of a fan blade, and a mold. The integral manufacturing process comprises the following steps of: (1) paving and pre-curing an upper shell of a blade which is free from an enhancement layer; (2) paving other cloth layers of a lower shell except the enhancement layer; (3) paving a vacuum bag film and a diversion material on an inner support frame provided with a gap, paving enhancement layers of upper and lower molds, and leaving abutment joints of the cloth layers in the gap of the inner support frame; (4) hoisting an inner support frame which is finally obtained in the step (3) at the root end of the lower mold; (5) performing butted joint on the cloth layers of the enhancement layers in sequence in the gap of the inner support frame; and (6) matching the molds, and performing vacuum infusion. The enhancement layers at the root ends of the upper and lower half molds of the blade are infused together, so that mold matching seams are avoided, and the root end strength is high.
Description
?
Technical field
The present invention relates to the wind power generation blade field, be 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 links to each other 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 the moulding but traditional blade production technology pattern is blade, by matched moulds behind the coating bonded adhesives upper female die is integrated again.Because adopted the secondary bonding forming, often there are the problems such as bonding plane too highly needs polishing, adhesive surface to cross low to be inconvenient to bond, the extra reinforcement of bonding plane needs.The present invention 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 do not had traditional defective.
Summary of the invention
Technical purpose of the present invention 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 purpose of the present invention, the technical solution used in the present invention is: fan blade butt enhancement layer integral production technique comprises the steps: 1) finish laying, precuring without enhancement layer blade upper shell; 2) lower house is finished the laying of all the other layer of cloths except enhancement layer; 3) after containing inner support frame laying vacuum bag film jaggy and water conservancy diversion material, 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 purpose of the present invention, another technical solution used in the present invention 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 the 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.
Prerequisite of the present invention is an existing patrix housing (containing enhancement layer) of finishing 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 the 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 behind the 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 invention;
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 embodiment of the invention is described in detail: present embodiment is to implement under the prerequisite in technical solution of the present invention, provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
Referring to Fig. 1, the step of manufacture craft of the present invention is: 1) finish laying, precuring without the upper shell of enhancement layer, without the housing 2 of enhancement layer; 2) counterdie is finished the laying of all the other layer of cloths except enhancement layer 3; 3) after inner support frame 5 lays vacuum bag film 4 and water conservancy diversion material, 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 finished 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 the 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.
Prerequisite of the present invention is an existing patrix housing of finishing 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 the 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 behind the 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.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
