Description

Technical Field

[0001] This utility model relates to the field of copper tube processing technology, specifically to an automatic copper tube sawing machine. Background Technology

[0002] A U-shaped tube consists of two parallel tube bodies and an arc-shaped connecting part. The outer radius of the tube body is R, and the distance between the center lines of the two tube bodies is 2L. The smaller the value of L / R, the more compact the pipeline can be when applied to a specific pipeline. Currently, U-shaped tubes are mostly processed by bending copper tubes into an S-shaped structure using a bending machine, and then cutting the bent S-shaped copper tube in the middle to cut multiple U-shaped tube joints. Existing devices are complex in structure, require human-machine cooperation, and have low work efficiency. Although patent publication number CN218612001U can saw the workpiece, the S-shaped copper tube needs to be manually placed during cutting, which is slow, inefficient, and inconvenient to use.
