Problems solved by technology

The blade needs a certain amount of vacuum treatment in the mold closing and bonding process. The traditional vacuum treatment during mold closing is to reserve the vacuum film on the parting surface when tearing off the auxiliary materials in the bonding process, then stick the vacuum tape, and finally wrap it. Vacuum treatment, which is not only time-consuming and labor-intensive, but also the vacuum area is easy to leak, and the vacuum pass rate is extremely low. Finally, it is necessary to find the leaking part, which increases the blade mold cycle and directly affects the entire production efficiency.

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] The invention provides a method for mold closing of wind power blades. Vacuum is required for mold clamping, that is, a vacuum is required in the bonding process of blade mold clamping. When the auxiliary materials are torn off in the bonding process, a vacuum film is reserved on the parting surface. Then reapply the vacuum tape on the outside of the mold edge, and seal the reserved vacuum film through the vacuum tape, so that the parting surface is in a negative pressure state, and the skin is tightly adsorbed on the mold, so that the skin can be together with the mold. Flip and close the mold.

[0021] Specific steps are as follows:

[0022] Step 1, laying the blade skin glass fiber cloth 2 in the main mold, and the glass fiber cloth 2 needs to cover the edge prism 1 of the main mold;

[0023] Step 2, prepare the first rubber-absorbi...

Abstract

The invention discloses a wind turbine blade mold closing method. In the method, by pre-laying a vacuum layer on a mold closing mold splitting surface, mold closing bonding can be directly performed after two vacuum layers are torn off after blade forming. By means of the method, the operation time of staff can be shortened, the mold occupation cycle of the bonding process can be shortened, it isavoided that on-site vacuum wrapping is preformed again in a traditional method, and the passing rate of vacuum inspection is significantly increased.

Description

technical field [0001] The invention relates to the technical field of forming wind power blades, in particular to a mold closing method for wind power blades. Background technique [0002] At present, due to the huge size of wind power blades, the manufacturing method usually adopts the assembly method. First, the main beam, web and other parts of the blade are formed on a special mold, and then the two shells, web and other components are assembled on the main mold. The components are glued and assembled together with adhesives, and the integral blade is made after mold closing, pressurization and curing. The blade needs a certain amount of vacuum treatment in the mold closing and bonding process. The traditional vacuum treatment during mold closing is to reserve the vacuum film on the parting surface when tearing off the auxiliary materials in the bonding process, then stick the vacuum tape, and finally wrap it. Vacuum treatment is not only time-consuming and labor-inten...
