Abstract
The invention relates to the field of wind power generating blades, and particularly relates to a fan blade root refining process and a die. The fan blade root refining process comprises the following steps of: (1) mounting refining flanges at the root ends of an upper die and a lower die, which are used for forming a blade; (2) dividing the refining flanges into upper die flanges and lower die flanges along die dividing wires of the upper die and the lower die, wherein the upper die flange is fixedly arranged on the upper die, and the lower die flange is detachably fixed on the lower die through a fixing device; (3) laying a cloth layer, wherein the lower die flange is fixed on the lower die, and the cloth layer at the blade root end is laid near the flanges; and (4) after the blade is cured, opening a lower die flange fixing device, wherein the lower die flange departs from the lower die, and the blade is de-molded. According to the fan blade root refining process provided by the invention, the problem that the flange is difficult to machine can be solved; when the cloth layer is paved; the cloth layer at the root end is near the refining flanges; and the lower die flange is de-molded after the blade is formed, so that the blade is smoothly de-molded.
Description
Technical field
The present invention relates to wind power generation blade field, be specifically related to a kind of fan blade root process for refining and mould thereof.
Background technology
Wind-power electricity generation market, through high speed development in a few years, has entered the cruel market competition stage now.Blade, as the important component part of whole blower fan, is faced with the market price equally and day by day drops, and the predicament that raw material, labor cost go up.Under such overall situation, lean is produced, to reduce unnecessary waste imperative.
The plane treatment that blade is connected with complete machine wheel hub, existing have two kinds of modes, a kind of mode of built-in turnbuckle, when layer of cloth is laid, carrys out control plane by butt locating flange, but it is because will play the effect of bolt, therefore processed complex.Another kind cuts out a plane by puncher at blade root after blade forming, so just needs when blade laying, need layer of cloth to grow 3-5cm, cause waste at butt.
Butt process for refining of the present invention is united two into one at the mode of pre-buried mode and punching, the complexity of the butt locating flange both avoided, and turn avoid as cutting out plane and reserve the waste of layer of cloth afterwards.
Summary of the invention
Technical purpose of the present invention overcomes the problems of the prior art, provides a kind of butt at upper/lower die to install refining flange, blade root layer of cloth processes relatively simple, that save cloth layer material fan blade root process for refining and mould near refining flange, refining flange.
For realizing object of the present invention, the technical solution used in the present invention is: fan blade root process for refining, comprises the steps: 1) at the butt of the upper and lower mould for formed blades, refining flange is installed; 2) refining flange is divided into upper and lower modulus method blue along the die parting line of upper and lower mould, and patrix flange is fixed on mold, and counterdie flange is removably fixed on bed die by fixture; 3), when laying layer of cloth, counterdie flange is fixed on bed die, and blade root layer of cloth is laid near flange; 4) after blade cures completes, open counterdie flange fixing device, counterdie flange departs from bed die, the blade demoulding.
Aforesaid fan blade root process for refining, flange install and the demoulding time and mould be an acute angle.
Aforesaid fan blade root process for refining, described fixture is can the fixed hinge of folding.
For realizing object of the present invention, another technical solution used in the present invention is: fan blade root refines mould, it is characterized in that: comprise for formed blades upper and lower mould, be installed on the refining flange of upper and lower mould butt, refining flange is divided into upper and lower modulus method blue along the die parting line of upper and lower mould, patrix flange is fixed on mold, counterdie flange is removably fixed on bed die by fixture, and blade root layer of cloth is laid near flange; Counterdie flange is made to depart from bed die by opening counterdie flange fixing device.
Aforesaid fan blade root refines mould, flange install and the demoulding time and mould be an acute angle.
Aforesaid fan blade root refines mould, and described fixture is can the fixed hinge of folding.
The present invention adopts refining flange at blade root, and blade root layer of cloth direct adjacent flange when laying is laid, and the blade root after shaping is without the need to repairing type, and length of blade is design length; Because of the reason of draft angle, patrix flange design is fixed, and counterdie flange can folding by fixed hinge, and when laying layer of cloth, butt layer of cloth, near refining flange, makes the demoulding of counterdie flange after blade forming, make the smooth demoulding of blade.
Accompanying drawing explanation
