Description

Technical Field

[0001] The invention relates to the technical field of wind power generation, and in particular to a wind power blade flash cutting device. Background Art

[0002] With the transformation of the global energy structure and the increasing demand for renewable energy, wind energy has developed rapidly as a clean and efficient form of energy. As one of the key components of wind turbines, the performance of wind turbine blades directly affects the efficiency and safety of the entire unit. However, in the production process of wind turbine blades, due to material properties and processing technology, wind turbine blade flash is a phenomenon produced during the manufacturing process of wind turbine blades. It usually appears on the edge of the blade, especially after the mold bonding and curing of the blade, the bonding glue and glass fiber cloth at the bonding of the blade mold seam exceed the blade contour. The blade flash will not only affect the appearance, but more importantly, it may reduce the aerodynamic performance of the blade and even cause safety hazards.

[0003] Most of the wind turbine blade flash cutting devices currently on the market can only perform single-side operations. For blades with multiple flashes, multiple adjustments are required to complete the entire processing, greatly reducing work efficiency. In addition, existing equipment usually lacks design considerations specifically for maintaining stability during long-distance cutting, especially when acting directly on longer flashes without proper support, which can easily lead to reduced cutting accuracy and potential safety risks.
