Description

Technical Field

[0001] The invention relates to the field of laser cutting facilities, and in particular to laser cutting equipment for processing hardware parts. Background Art

[0002] Hardware refers to five metals: gold, silver, copper, iron and tin. They can be made into works of art or metal devices such as knives and swords through artificial processing. Hardware in modern society is more extensive, such as hardware tools, hardware parts, etc., and laser cutting equipment is often used for cutting in the processing of hardware parts. The laser cutting equipment uses a focused high-power density laser beam to irradiate the workpiece, so that the irradiated material quickly melts, vaporizes, abslates or reaches the ignition point, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the cutting of the workpiece. Laser cutting is one of the thermal cutting methods.

[0003] When existing laser cutting equipment is used to cut hardware parts for a long time, the dissolved material in the laser cutting process will adhere to the sword grid, thereby forming slag. Excessive accumulation of slag will affect subsequent laser cutting operations. Therefore, in order to avoid this phenomenon, workers are often required to manually clean and remove the slag on the sword grid. The slag removal process greatly increases the labor intensity of the workers, and the manual slag removal efficiency of the workers is low. Summary of the invention
