Embodiment Construction

[0007] The present invention will be further described below in conjunction with examples of implementation.

[0008] The laser generated by the laser generator is condensed by the concentrator into high-energy rays and irradiated on the mirror. The mirror adjusts the angle to complete the cutting of materials of different shapes. The high-power laser beam heats the material. The laser generator of the laser generating unit Laser light is generated and converged to a very small point through the lens. The energy of the laser is concentrated to a small range in a unit space, making it have very large energy. The laser is reflected to the material / cut workpiece through the emitting mirror , under the heating of a high-power-density laser beam, oxygen or other active gases are used instead of inert gases for melting and cutting. The material to be cut is ignited under the irradiation of the laser beam, and the intense chemical reaction with oxygen produces a larger heat source. T...

Abstract

The invention provides a magnetic separated laser oxidizing fusion cutting machine. The cutting machine is characterized in that oxygen or other active gases are adopted to replace inert gases to perform fusion cutting, and high-intensity magnetic fields are adopted to suck back wastes so as to replace an auxiliary air unit; under heating of high-power intensity laser beams, the speed that the temperature of a material surface rises to the boiling temperature is fast so as to avoid the fusion caused by heat conduction; the cut materials are ignited by irradiation of the laser beams so as to perform a fierce chemical reaction with the oxygen to generate a larger heat source; a part of materials is vaporized into steam and disappears, and a part of materials is sucked back by auxiliary airflows from the bottom of a cutting slot as ejecta; the cutting slot cut by lasers is thin, the cutting surface is smooth, the cutting speed is fast, the thermal deformation is small, the laser cutting is in no contact with the material surface, the cutting machine is suitable for processing large-sized products, the materials are saved, moreover, the cutting machine can be applied to sheet-metal processing of relevant industries such as heavy and light industries, medical industries and the like, cutting and shaping of rotators, stators and blades, manufacturing of various chains and parts of vehicular manufacturing industry, advertisement decoration and handicraft article manufacturing industries, etc.

Description

technical field [0001] The invention relates to a laser cutting machine, in particular to a laser forming machine. Background technique [0002] Einstein published "The Quantum Theory of Radiation" in 1916 based on Bohr's work. The article puts forward the theory of laser radiation, which is the core basis of laser theory. Einstein is therefore considered the father of laser theory. In this paper, Einstein distinguished three processes: stimulated absorption, spontaneous emission, and stimulated emission. The first two concepts are already known. Stimulated absorption means that atoms in a low-energy state absorb external radiation and transition to a high-energy state; spontaneous emission means that atoms in a high-energy state spontaneously radiate photons and migrate to a low-energy state. The characteristic of this kind of radiation is that the transition of each atom is carried out spontaneously and independently, and the process has no external influence and has n...
