AI Technical Summary
Existing copper tube cutting devices lack limiting mechanisms on both sides during the cutting process, which can cause the copper tube to shift left and right, affecting cutting accuracy.
The copper tube is positioned by a support roller, a clamping roller, and a limiting roller, which limit the upper and lower sides of the tube. The limiting roller also limits the left and right sides of the tube, ensuring the stability of the copper tube during movement and cutting.
It improves the precision of copper tube cutting, reduces the displacement of copper tubes during the cutting process, and reduces frictional damage.
