Between be each formed with the second groove 22.
The preparation method of the wind electricity blade web component of the present invention utilizes above-mentioned mould, so as to which wind electricity blade web be made
Component.The preparation method comprises the following steps：
S1, the groove 22 of die main body 1 and second is irrigated so that wind electricity blade web component is made.
In step S1, obtained wind electricity blade web component includes web body, upper flange portion and lower flange portion,
Upper flange portion and lower flange portion are connected to the both ends of web body.By being filled to two the second grooves 22 in mould
Glue realized and is integrally formed between web body and what lower flange portion of upper flange portion so that upper flange portion and lower flange portion be made out,
The quality of wind electricity blade web component is effectively ensured, reduces unnecessary maintenance, shortens the molding cycle of wind electricity blade, reduces behaviour
Make the labor intensity of personnel.
As shown in Figures 2 and 3, step S11 can be included before step S1, step S11 is to lay flange layer of cloth 6
On the inner side of body flange 2 in the first groove 21.
In step S11, it can effectively strengthen the structure in upper flange portion and lower flange portion by being provided with flange layer of cloth 6
Intensity, the quality of wind electricity blade web component is lifted, reduces unnecessary maintenance.Preferably, flange layer of cloth 6 can be glass fibers
Wei Bu.
In the mould of the present invention, the first module 3 and the second module 4 in the first groove 21 can be formpiston,
And first the material of module 3 and the second module 4 can be silica gel, be easy to the demoulding to the first module 3 and the second module 4, protect
Demonstrate,prove the quality of wind electricity blade web component.It is recessed can be first not placed in first for the first module 3 and the second module 4 in step s 11
In groove 21, it is easy to the setting of flange layer of cloth 6.
It can press between two modules 3 of body flange 2 and first and the second module 4 and be located at provided with lamellar body 5, i.e. lamellar body 5
In first groove 21, and the lamellar body 5 is located at the bottom land of the second groove 22.In step s 11, the bottom of flange layer of cloth 6 is located at piece
The top of body 5, the top of flange layer of cloth 6 turn to the top of body flange 2, are pressed from both sides using fixture in the place at interval of one meter or so
Fasten so that flange layer of cloth 6 is connected with the top of body flange 2.
