AI Technical Summary
In the cutting process, existing pipe cutting machines are prone to shift the pipe and affect the cutting flatness. Especially when cutting long pipes, the pipes are prone to be raised, resulting in the notch not perpendicular.
A pipe cutting machine with clamping limiting device is designed. By setting two limiting mechanisms on the left and right sides of the cutting wheel, the pipe is clamped with arc plates and extension plates, so that both ends are fixed during cutting. Make sure the cutting is smooth. At the same time, the long pipe is supported by a movable support plate to keep the pipe horizontal and ensure the cutout is vertical.
It effectively solves the problem of pipe shift during cutting, ensures cutting flatness and verticality of the cut, and is suitable for cutting long pipes.
