Description

Technical Field

[0001] The utility model relates to the technical field of fan blade processing devices, in particular to a punching device for fan blade processing. Background Art

[0002] The fan blade is one of the core components of the wind turbine, accounting for about 15%-20% of the total cost of the wind turbine. The quality of its design will be directly related to the performance and efficiency of the wind turbine. During the production of the fan blade, a hole needs to be opened at one end of the fan blade and installed on the wind turbine with bolts. Therefore, during the production of the fan blade, a punching device is required to open holes on the blade.

[0003] Usually, when punching blades using a punching device, the punching machine is a mechanical device that installs the raw materials, drives the punching die on the blade under the drive of a power mechanism, and completes the punching. Therefore, when punching the blades, the blades need to be moved to the punching area, and at the same time, the punching knife is driven downward under the action of mechanical force to open holes on the blades. When the blades are produced, they need to be designed with a certain curvature to ensure that the airflow can be promoted when the blades rotate. However, the curved design of the blades will cause the position of the blades to be uneven when placed on the conveyor belt, and the punching device will also exert a certain pressure on the blades during the downward pressure process, which will further cause the position of the blades to be offset, thereby affecting the accuracy of the punching position. So far, we have proposed a punching device for fan blade processing. Utility Model Content
