Embodiment Construction

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

[0008] The laser generated by the laser generator is condensed by the condenser into high-energy rays and irradiated on the reflector. The reflector 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 generation unit Generate laser light, converge to a very small point through the lens, the energy of the laser in the unit space is concentrated in a small range, so that it has a very large energy, the laser is reflected on the material / workpiece to be cut through the emitter mirror , Under the heating of a high-power density laser beam, oxygen or other active gas is used to replace inert gas for melting and cutting. The material to be cut is ignited under the irradiation of the laser beam, and a fierce chemical reaction with oxygen produces a larger heat source. The surface te...

Abstract

The invention provides an auxiliary air laser oxidizing fusion cutting machine of a compressor. The cutting machine is characterized in that oxygen or other active gases are adopted to replace inert gases to perform fusion cutting, and auxiliary airs are adopt strong airflows produced by a compressor, and 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 under heating of high-power intensity laser beams; 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 bulky commodities and 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 "Quantum Theory on Radiation" in 1916 on the basis of Bohr's work. The article puts forward the theory of laser radiation, which is the core foundation of laser theory. Therefore Einstein is considered the father of laser theory. In this paper, Einstein distinguished three kinds of 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 spontaneous and independent, and the process has no external influences, and there i...
