Embodiment Construction

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

[0008] The laser generated by the laser generator is condensed by the concentrator into high-energy rays and irradiated on the reflector. The angle of the reflector is adjusted to complete the cutting of materials of different shapes. The high-power laser beam heats the material to vaporize it in an instant. The laser generator of the unit generates laser light, which is concentrated to a very small point through the lens, and the energy of the laser light in the unit space is concentrated to a small range, making it have a very large energy, and the laser light is reflected to the material / material through the emitting mirror. On the workpiece to be cut, under the heating of the high power density laser beam, when the power density of the incident laser beam exceeds a certain value, the inside of the material irradiated by the beam begins to evaporate, forming holes....

Abstract

The invention provides a magnetic separated numerical control laser fusion cutting machine. The cutting machine is characterized in that magnetic forces are adopted to suck back the fused cut wastes, and a CNC (computerized numerical control) contouring control numerical control machine tool is taken as a control unit; the fused materials are sucked back by a suction-back probe which is utilized by intense magnetic fields produced by an electromagnetic converter; when the power density of an incident laser beam exceeds a certain value, the interior of the material at the beam irradiation point is subjected to vaporization to form holes, once the holes are formed, the holes are taken as black bodies to suck energies of all the incident laser beams; small holes are enclosed by fused metal walls, and the fused material which is coaxial with the laser beams is taken away by auxiliary resorption. A 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 metal cutting machine is suitable for processing large-sized products 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 "The Quantum Theory of Radiation" in 1916 on the basis of Bohr's work. The article proposes the theory of laser radiation, which is the core basis of laser theory. Therefore, Einstein is considered to be 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 radiation is that the transition of each atom is spontaneous and independent, and the process has no external influence and has no relationship...
