Technical Field

[0001] The present invention relates to the technical field of flying wing processing, in particular to a flying wing tool, a flying wing mechanism and a double-sided flying wing machine. Background Art

[0002] The traditional processing technology of heat exchange products generally adds pipes and fins separately first, and then uses welding, pipes inserted through fins, and tensioning pipes to achieve an interference fit between pipes and fins to make heat exchange products. The joints will produce additional contact thermal resistance, so the overall thermal resistance is high and the heat transfer efficiency is low during the heat exchange process.

[0003] Processing fins on aluminum body is a new type of heat exchange product. However, the existing processing method is to use single-sided linear mechanical scraping for processing, first scraping on one side of the aluminum, and then scraping on the other side of the aluminum, which has low processing efficiency. In addition, due to the high-intensity scraping, the scraping tool needs to be disassembled and maintained every day to maintain good sharpness. The existing mechanical scraping tool disassembly process is time-consuming and labor-intensive, which invisibly increases production intensity and reduces processing efficiency.
