Laser cutting equipment

Technical Field

The invention relates to the technical field of laser cutting, in particular to laser cutting equipment.

Background

Laser cutting is a process of irradiating a workpiece with a focused high power density laser beam to rapidly melt, gasify, ablate or reach a fire point, while blowing off molten material with a high velocity gas stream coaxial with the beam to effect cutting of the material. Compared with other thermal cutting methods, the technology has the characteristics of high cutting speed and high quality. The basic principle is to focus the laser light on the material and to locally heat the material until the melting point is exceeded. The depth of laser cutting is primarily dependent on factors such as laser power, cutting speed, focal position, and material properties. When cutting a thick steel plate, a light beam with a large focal depth should be used to obtain a cut surface with good perpendicularity. Meanwhile, the depth of focus is large, the diameter of a light spot is increased, the power density is reduced, and the cutting speed is possibly reduced. Therefore, in order to maintain a certain cutting speed, it may be necessary to increase the laser power. On the other hand, the thin plate is cut by adopting smaller focal depth, so that the light spot diameter is small, the power density is high and the cutting speed is high.

The laser cutting equipment on the market at present cannot be automatically adjusted according to the thickness of a required cut plate, so that the efficiency of the laser cutting equipment is lower when the thick plate is cut, and when the thin plate is cut, the resource waste is caused if the cutting equipment with higher power is adopted; we therefore propose a laser cutting apparatus to address this problem.
