Technical Field

[0001] The utility model relates to the technical field of HVAC elbow processing, in particular to a clamping mechanism used for cutting HVAC elbows. Background Art

[0002] Multiple pipes are required for the installation of the HVAC system. Since the pipes are laid in a ring, HVAC elbows are needed at the corners of the room to connect the two sections of the pipes. At this time, the HVAC elbows need to be cut according to the spacing between the two sections of the pipes, so a cutting machine is needed to cut the pipes.

[0003] In the prior art, although the pipe cutting machine can clamp and position the pipe during use, it is affected by the usage conditions and the different curvatures of the pipes, resulting in incompatibility with the clamping mechanism on the pipe cutting machine. It cannot effectively clamp and position the bent pipes with different curvatures, has poor applicability, and cannot meet the usage requirements. Therefore, we propose a HVAC bent pipe clamping mechanism to solve the above problems. Utility Model Content
