Embodiment Construction

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

[0008] The laser generator generates laser light which 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 to vaporize it instantly, and the laser beam generates The laser generator of the unit generates laser light, which is converged 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, so that it has very large energy, and the laser light is reflected to the material / On the workpiece to be cut, under the heating of the high power density laser beam, the surface temperature of the material rises to the boiling point quickly enough to avoid melting caused by heat conduction, part of the material is vaporized into steam and disappears,...

Abstract

The invention relates to a magnetic-partition laser vaporization metal cutting forming machine. In the invention, waste materials are sucked back by a strong magnetic field instead of an auxiliary gas unit; when a material is heated by high-power density laser beams, the surface temperature of the material is increased to the temperature at a boiling point in a high speed so as to avoid melting caused by heat conduction, wherein, a part of the material is vaporized to form steam and disappears, and a part of the material is taken as a spraying object to be sucked by a suck-back probe. By adopting a laser cutting mode, the magnetic-partition laser vaporization metal cutting forming machine has the advantages that the obtained cutting seam is fine, the obtained cutting surface is smooth, the cutting speed is fast, heat deformation is small, the contact with the surface of the material can be avoided during the cutting process, more materials can be saved, and the machine is suitable for machining large products. The magnetic-partition laser vaporization metal cutting forming machine can be applied to machining sheet metals in the heavy / light industry, medical treatment industry and other related industries, cutting and forming rotors, stators and blades, and manufacturing various chains and components in the automobile manufacturing industry; and meanwhile the machine is also suitable for the advertisement and decoration industry, the artwork manufacturing industry and the like.

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...
