However, since the inner wrapping is pasted on the inner wall of the joint of the blades in the upper and lower molds, it is inconvenient to apply pressure to it, which makes it difficult to closely fit the inner wrapping and the inner wall of the blade in the prior art, which affects the shape of the inner wrapping and is easy to Cause inner edge void phenomenon

[0019] figure 1 It is the process flow diagram of the fan blade inner wrapping mold reinforcement process of the present invention, which is combined below figure 1 The process flow of the present invention is exemplified but the present invention is not limited to the above process flow under the same concept.
[0020] The fan blade inner edge mold reinforcement process of the present invention comprises the following steps: a. laying the working surface shell 10 and the aerodynamic surface shell 20 respectively in the upper mold and the lower mold of the fan blade mould, that is, laying the first layer of shell; b. The upper and lower molds of the fan blade mold are laid with main spar caps, core materials, and the second shell in sequence; c. Place the shear ribs of the fan blades inside the upper mold or the lower mold, and then lay them on the inner wall of the blade shell in sequence Isolation film with holes and diversion net to form a vacuum system. Vacuum the gap for...

The invention discloses a reinforcing technology of a blower fan blade inner edging die. According to the technology disclosed in the invention, a prior blower fan blade inner edging laying technology is added with an inner edging reinforcing step by arranging an inner edging reinforcing die on inner wall of a blade leading edge in a lower die. Shape of the inner edging reinforcing die is corresponded with that of the inner wall of the blade leading edge, and the two can be tightly combined. Iron wires are arranged on combination spot of the inner edging reinforcing die and the inner wall of the blade leading edge. When the inner edging is laid, the inner edging reinforcing die can be tensioned through the iron wires, so that a glass fiber cloth, which is the inner edging, laid on exterior of an inner edging die is tightly bonded with the inner wall of the blade leading edge through resin and an adhesive, etc.
Description
technical field [0001] The invention relates to a process for laying an inner wrapping mold of a fan blade, in particular to a process for reinforcing an inner wrapping mold of a fan blade, which can make the bonding between the inner wrapping of the fan blade and the inner wall of the blade more tight. Background technique [0002] Fan blades are an important part of wind turbines. In the process of using molds to manufacture fan blades, when the blade lower mold and upper mold are clamped, in order to make the finished product durable, the edges of the blade shells in the upper and lower molds need to be tightly bonded together. At this time, the method of pasting multiple layers of glass fiber cloth to the inner wall of the joint of the fan blade through resin and adhesive to form an inner edge is often used to strengthen the bonding between the edges of the shell. However, since the inner wrapping is pasted on the inner wall of the joint of the blades in the upper and l...
