Description

Technical Field

[0001] This utility model relates to the field of pipe processing equipment technology, and in particular to a laser pipe cutting machine. Background Technology

[0002] Laser tube cutting machines are used to cut tubes using laser technology. Current laser tube cutting machines typically employ a set of movable chucks and a set of fixed chucks to clamp the tube. The movable chucks then move the tube to its correct position, allowing for laser cutting. However, this structure is inflexible in terms of material processing methods, cannot handle processing of more parts of the tube, and cannot process leftover tube material. Furthermore, the tube positioning and lifting devices in laser cutting machines usually consist of two sets of structures. One set uses an adjustment device to adapt to product specifications, which is typically manually adjusted. The lifting device controls the tube's lifting for clamping by the chucks. This structure is complex, costly, and inconvenient to adjust, thus requiring improvement. Utility Model Content
