Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber laser cutting machines, in particular to an optical fiber laser cutting machine with a positioning device. Background Art

[0002] Fiber laser cutting machine is a laser cutting machine that uses a fiber laser generator as a light source. Fiber laser is a new type of fiber laser developed internationally that outputs a high-energy-density laser beam and focuses it on the surface of the workpiece, causing the area on the workpiece irradiated by the ultra-fine focal spot to melt and vaporize instantly. Automatic cutting is achieved by moving the spot irradiation position through a CNC mechanical system.

[0003] When the existing fiber laser cutting machine is actually used, the worker needs to adjust and position the plate after placing the plate to be cut on the cutting table. The process is cumbersome, and harmful smoke is easily generated when using laser cutting, which cannot be removed in time and cannot guarantee the health and safety of the workers. After the cutting is completed, the waste generated by the cutting needs to be removed from the cutting table, making the cutting work time-consuming and laborious. For this reason, we propose a fiber laser cutting machine with a positioning device to solve the above problems. Utility Model Content
