Numerical-control laser fracture-control cutting machine

Abstract

The invention relates to a numerical-control laser fracture-control cutting machine. In the invention, a CNC (Computerized Numerical Control)-contouring control machine tool is taken as a control unit; an auxiliary gas unit sucks back the whole friable and falling waste materials by utilizing strong airflow generated by a compressor with the aid of magnetic partition; and high-speed and controllable cut-off operation is carried out on a friable material which is easy to be broken due to heat by a laser beam heating mode, and during the cutting process, 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 in the event that the material is heated by high-power density laser beams, 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 back by the auxiliary airflow from the bottom of a cutting seam. By adopting a laser cutting mode, the numerical-control laser fracture-control cutting machine based on the auxiliary gas from the compressor 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 numerical-control laser fracture-control cutting 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...
