Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, and in particular to a control system of a plate-tube integrated laser tube cutting machine. Background Art

[0002] In recent years, the domestic demand for laser cutting machine tools has increased rapidly. The growth in demand for fiber laser cutting machine tools is particularly prominent due to their many advantages such as easy maintenance, low consumption cost, and excellent cutting cross-section.

[0003] Laser cutting machine is to focus the laser emitted from the laser into a high power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material is eventually cut, thereby achieving the purpose of cutting. Laser cutting replaces the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, no limitation on cutting pattern, automatic typesetting to save materials, smooth incision, low processing cost, etc. It will gradually improve or replace the traditional metal cutting process equipment. The mechanical part of the laser cutter head has no contact with the workpiece and will not scratch the workpiece surface during operation; the laser cutting speed is fast, the incision is smooth and flat, and generally no subsequent processing is required; the cutting heat affected zone is small, the plate deformation is small, and the cutting seam is narrow (0.1mm-0.3mm); the incision has no mechanical stress and no shear burrs; the processing accuracy is high, the repeatability is good, and the material surface is not damaged; CNC programming can process any plane diagram, and can cut a large whole plate without opening a mold, which is economical and time-saving.

[0004] With the development of laser cutting machines, people have higher and higher requirements for their processing speed and processing accuracy. The servo system, cooling system, laser system, air conditioning system, and control software system in the existing laser cutting machine control system are generally independent of each other. The operation of this system is relatively complicated. When a function needs to be started, the start button of the function needs to be pressed manually. When a function needs to be stopped, the stop button of the function also needs to be pressed manually. This places high demands on the operator, and the operator is prone to making mistakes during the operation. At the same time, the existing plate-tube integrated laser cutting machine control system has low integration, rigid operation, and inconvenient operation. Furthermore, the existing plate-tube integrated laser cutting machine control system has a slow control process, resulting in poor cutting processing effect.
