Description

Technical Field

[0001] The utility model relates to a flying knife cutting machine for pipes, belonging to the technical field of pipe production equipment. Background Art

[0002] At present, as an important industrial raw material, pipes play a key role in multiple industries. With the development of industrial technology, the requirements for the processing precision and efficiency of pipes are getting higher and higher. Traditional pipe cutting methods, such as grinding wheel cutting and sawing, although meeting the production requirements to a certain extent, have problems such as low efficiency, low precision, complex operation, and safety hazards. After retrieval, it is found that a Chinese patent with the publication number CN213917161U discloses a pipe cutting device. In this patent, the pipe is placed between the left pipe clamping housing and the right pipe clamping housing. By rotating the clamping operating part, the clamping block moves along the clamping guide rail, so as to clamp both ends of the pipe, ensuring that the pipe does not move during the cutting process. Adjust the position of the right pipe clamping housing to align it with the cutting device, move the housing according to the length to be cut, and make fine adjustments through the moving handle. Finally, start the cutting device, align and cut the pipe. After cutting is completed, operate the clamping operating part and the moving handle in reverse to loosen the clamping block and the right pipe clamping housing, and take out the cut pipe. When the pipe is cut by the cutting device in this patent, the saw blade of the cutting device cuts the pipe downward. Due to the slow cutting speed, burrs will appear on the surface of the cut pipe, affecting the quality of the pipe. Summary of the Invention
