Description

Technical Field

[0001] The utility model relates to the technical field of pipe processing, in particular to an air-conditioning pipe feeding machine. Background Art

[0002] Currently, the round tube loading machines on the market are mainly used for loading solid round bars and hollow round tubes. The loading requires that the axis of the round bar or round tube is straight, and there must be no other features at the outer diameter that affect the rolling of the round tube. There are certain requirements for the appearance of the loaded product.

At the same time, there are relative position requirements for the direction of the pressure plate and the bending angle of the tube, which will place higher demands on the feeding machine. Therefore, there are fewer matching feeding equipment and the degree of automation is low. Summary of the Invention
