The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Referring to accompanying drawing 1-3, the preparation method of the disclosed this vertical axis aerogenerator flabellum shell of the present invention, its flabellum shell adopts the thin plate of aluminum alloy material to make, and it carries out according to following steps:
A, the aluminium alloy sheet of bulk is cut into the rectangle thin plate 2 that meets the flabellum shell sizes.
B, an end of rectangle thin plate 2 is inserted in the inner fixed support 3 of fixator 4 and fixing; This fixator 4 tops one side is connected with circular arc bolster model 5; Circular arc bolster model 5 fits tightly with rectangle thin plate 2, and this circular arc bolster model 5 is positioned at 1/3rd places of rectangle thin plate.In the practical operation; Fixator 4 for frame structure and be fixedly mounted on ground or workbench on; Be connected with fixed support 3 in the bottom of frame structure; Fixed support 3 in the present embodiment is two vertical and fixator 4 bottoms are provided with gripper shoes, and rectangle thin plate 2 is inserted between two gripper shoes and fixes.
C, impact, form and the corresponding arc surface 10 of circular arc bolster model 5 radiuses to the part of the bottom 1/3rd of rectangle thin plate 2 with the top of 1 pair of rectangle thin plate 2 of circular impact device.Number of times that knocks and dynamics have operating personnel to control, and can be that manual work is beaten, and also can be mechanically actuateds.
D, the rectangle thin plate 2 that will have an arc surface take out; These rectangle thin plate 2 middle(-)third places are lain in a horizontal plane in into the top of angle bolster model 6; And fit tightly with it; The bottom that constitutes two roundels of this one-tenth angle bolster model 6 is provided with steel baffle plate 8, and steel baffle plate 8 is arranged on the workbench, is provided with Cheng Jiao gap 9 between two roundels.
E, on rectangle thin plate 2, place a round-formed hornwork 7; This round-formed hornwork 7 is applied pressure at right angle; Make its compressing rectangle thin plate 2 be moved downward to steel baffle plate 8 upper surfaces, and form arc chord angle 11 with rectangle thin plate that round-formed hornwork is fitted along the Cheng Jiao gap 9 that becomes angle bolster model 6.
F, the rectangle thin plate 2 that will oppress moulding are placed on the flabellum make-up machine fixedly, and moulding gets final product.This step mainly is to adding the fixedly moulding of annexes such as hog frame in rectangle thin plate 2 integral body and the flabellum shell.
Circular arc bolster model 5 is cylindrical or other have the roundel of arc surface, and the arc radius of its arc surface is corresponding with the arc surface radius on the flabellum shell.In the present embodiment, the radius of this circular arc bolster model 5 is 40cm.
Circular impact device 1 has the roundel of arc surface for high cylindrical of material hardness or other, and its arc surface is smooth clean and tidy, to guarantee not damage the fineness of rectangle thin sheet surface.
The radius of round-formed hornwork 7 is identical with the radius of the arc chord angle 11 of flabellum shell, and the horizontal range in Cheng Jiao gap 9 is greater than the diameter 1.5-6.5cm of round-formed hornwork 1.The radius that is the arc chord angle of the flabellum shell made according to actual needs of the size of round-formed hornwork 7 is made.In the present embodiment, the radius of round-formed hornwork 7 is 7.5cm, and the horizontal range that forms gap, angle 9 is 17cm.
It is cylindrical becoming angle bolster model 6 or other have the roundel of arc surface, and its arc surface and rectangle webs into tight are fitted, and the diameter of this one-tenth angle bolster model 6 is more than 2 times of round-formed hornwork 1 diameter.Becoming the diameter of angle bolster model 6 in the present embodiment is 30cm.
For being of the required size of the flabellum shell that guarantees to make moulding, the rectangle thin plate is divided into three parts, promptly need carry out process operation wherein adjacent two 1/3rd sections.In the art, usually the arc chord angle that processes is called " R angle ", the radius of arc chord angle is the radius at R angle.After the R angle of rectangle thin plate and arc surface machined; Place it on the flabellum make-up machine of vertical axis aerogenerator, will be used to then to support and the inner supporting device that improves intensity is fixed in this flabellum shell, through the operation to make-up machine; Accomplish the integral body processing of flabellum; The steel plate that will have the hole that facings the wind at last is fixed on the flabellum shell, and its two ends are connected, and makes it form the blade structure of sealing.
