Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a laser cutting machine for metal processing which is easy to clean. Background Art

[0002] Laser cutting is a new cutting method. In metal processing, metal parts need to be segmented due to production needs. Compared with traditional oxyacetylene, plasma and other cutting processes, laser cutting has a fast speed, a smooth cut surface and basically does not require post-processing. It can also cut different shapes by controlling the relative position of the workpiece and the laser processing head.

[0003] For example, the Chinese utility model patent document, with the publication number CN220372451U, discloses a pipe laser cutting device, which belongs to the field of laser cutting technology, and includes: a first support frame, one end of which is provided with a laser cutting head moving along the width direction; a clamping mechanism, including a plurality of pipe clamps, a plurality of connecting tubes, the axial direction of the connecting tubes is the same as the length direction of the first support frame, and a plurality of connecting tubes are arranged in an array in the horizontal direction on a pair of fixed plates arranged at intervals, the fixed plate is slidably connected to the first support frame in the length direction of the first support frame, the bottom of the fixed plate is connected to the movable end of the linear mechanism, the pipe clamp is arranged at one end of the connecting tube facing the laser cutting head, and is used to clamp the pipe passing through the connecting tube; a driving mechanism is connected to the plurality of connecting tubes, and is used to drive the connecting tubes to rotate.
