Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe cutting, in particular to a flying saw machine for steel pipe cutting. Background Art

[0002] A flying saw primarily uses a high-speed rotating saw blade to drive the material being processed. In steel pipe processing, the flying saw typically operates in sync with the production line. When the pipe reaches the specified length, the flying saw starts, and the high-speed rotating saw blade, driven by a drop cylinder, presses against the pipe. Friction between the saw blade and the cut metal generates heat, melting or softening the metal at the cut edge. The teeth then eject the melted or softened metal along the tangential direction, completing the cutting process.

[0003] During the cutting process, flying saws generate flying chips due to the friction and impact between the high-speed rotating saw blade and the material being cut. These flying chips not only pose a threat to the operator's safety, but may also cause damage to the equipment and the surrounding environment. Existing flying saws cannot effectively isolate the cutting area, effectively recover the flying chips, or suppress their splashing. Utility Model Content
