Description

Technical Field

[0001] The invention relates to the technical field of bar laser cutting, and in particular to an intelligent laser cutting system for bar processing. Background Art

[0002] Laser cutting is a processing method that uses high-power density laser as a heat source, through computer-aided design and computer-aided manufacturing technology, according to the designed cutting trajectory, so that the workpiece is irradiated with a laser beam to achieve surface melting, evaporation or decomposition to form an incision. During the processing of the rod, laser cutting uses a high-power density laser beam to irradiate the surface of the rod, causing the material to melt, vaporize or burn rapidly, thereby achieving the purpose of cutting holes on the surface of the rod.

[0003] When existing rods are cut on different sides, they usually need to be manually flipped over to expose the new side that needs to be cut. This step is not only time-consuming, but also reduces the efficiency of the entire production line. In addition, the wire beam generated during laser cutting has high energy and strong brightness. Operators need to be exposed to this environment for a long time to observe the cutting, which may cause damage to human eyes, such as retinal burns, decreased vision, etc., and therefore face higher health risks.

[0004] For example, a PVC pipe laser cutting machine disclosed in the announcement number CN118492685A, although the laser cutting machine in this patent realizes the abutment and positioning of the inner wall of the PVC pipe, it is mainly used to fix and adjust the position of the PVC pipe during the cutting process to ensure the accuracy of the cutting. However, if it is to achieve cutting of different surfaces of the PVC pipe, it is still necessary to manually or mechanically flip the pipe to a new cutting position, and the laser cutting head in this patent is completely exposed when cutting the pipe. However, the wire harness generated when cutting the pipe with a laser has high energy and strong brightness. If there is no protective structure, the laser will cause damage to the operator's eyes.
