Background
The fan blade is one of the core components of the wind driven generator, accounts for about 15% -20% of the total cost of the fan, and the design quality of the fan blade is directly related to the performance and benefit of the fan.
In 1888, the Americans Charles F.Brush built a first fan for power generation, and the fan blades of the first fan are designed to be flat plates, so that the efficiency is low. In 1891, when Danish Poul LaCour designs a fan blade, an aerodynamic concept is introduced, so that a more scientific design method of the fan blade is initiated. Through the development of hundreds of years, the fan blade is greatly changed from the structure, the shape and the manufacturing material. Along with the increase of the installed capacity of a single fan, the diameter of a fan blade is increased continuously. According to data statistics, the wind energy utilization rate can be increased by about 12% when the diameter of the fan blade is increased by 6%. The diameter of the existing 2 megawatt fan blade can reach 80 m. However, the increase of the diameter of the fan blade also brings difficulty in manufacturing, and meanwhile, the transportation and installation cost of the blade is greatly increased; the existing fan blade cutting machine is low in working efficiency and narrow in applicable direction, and can only process and cut aiming at special sizes.
Therefore, in order to solve the above problems, a fan blade cutting machine is needed, which can improve the working efficiency, increase the application range, and process blades of different sizes.
