Embodiment

[0051] 1) Make the leading edge sticking corner mold used for integral infusion molding;

[0052]The sticking angle mold used for integral infusion molding is made in two parts, one part is formed in the lower shell mold 7 of the blade, and the other part is formed in the upper shell mold 10 of the blade. Through the hydraulic turning system, the upper shell mold of the blade is formed Turn it over 180°, and bond the bottom surface and the profile of the front edge bonding angle into one. In order to increase the rigidity and prevent deformation, you can fill the back of the leading edge bonding angle mold with foam or honeycomb material 15. The manufacturing process can be divided into the following steps ;

[0053] a) making the bottom surface 9 of the leading edge sticking angle mold at the leading edge flange 8 of the lower shell mold 7 of the blade;

[0054] b) making the front edge flange 11 of the upper casing mold 10 of the blade and the profile surface 12 of the fron...

Abstract

The invention belonging to the technical field of composite materials, and provides a method for integrally forming a blade lower shell of a wind power generation machine and a front edge adhering angle. The method for integrally forming the blade lower shell (2) of the wind power generation machine and the front edge adhering angle (6) comprises the steps of: manufacturing a front edge adhering angle die (14), fixing the front edge adhering die, integrally pouring and forming the front edge adhering angle (6) and the blade lower shell (2); integrally pouring and forming the front edge adhering angle and the lower shell by using the front edge adhering angle die (6); and curing the front edge adhering angle by using heat discharged by the curing of the lower shell (2). The problem caused by manual pasting of the front edge adhering angle is effectively avoided, the quality of front edge adhering is improved, time of singly manufacturing the front edge adhering angle and waiting the curing of the front edge adhering angle is saved, operation environment is improved and production efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and mainly relates to a method for integrally forming a lower shell of a wind power generation blade and a bonding angle of a leading edge. Background technique [0002] During the forming process of wind power blades, due to their large size and the presence of supports inside, it is difficult to form them at one time. Generally, the blades are divided into upper and lower shells to make them, and then the upper and lower shells are bonded to make the upper and lower shells Form a whole leaf. In order to ensure sufficient bonding strength, the front edge bonding angle must be used to increase the bonding area when the upper and lower shells are bonded. Wind power generation blades can be made in the following steps, such as figure 1 : [0003] a) Lamination of upper and lower shells. This step involves laying fiberglass cloth onto the surface of the mold as reinforcement for the ...
