Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to laser pipe cutting equipment with an automatic feeding structure. Background Technology

[0002] In the field of pipe processing, laser pipe cutting machines have become key equipment for cutting and processing various materials such as metal pipes and composite pipes due to their advantages of high cutting precision, small heat-affected zone, and high processing efficiency. They are widely used in aerospace component manufacturing, automotive chassis processing, building steel structure production, medical device research and development, and many other industries. However, most existing laser pipe cutting machines lack a stable limiting and guiding structure for the pipes in their conveyor frames. Due to deviations caused by manual placement and pipe offsets or shaking during transport, the pipes cannot move horizontally and dock with the chuck assembly. Therefore, multiple stops are set on the conveyor frame of the laser pipe cutting machine, but the distance between adjacent stops is fixed. Since the size and shape of each batch of pipes are different, all stops need to be replaced, affecting production.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content
