Abstract
Description
Technical Field
[0001] The invention relates to the technical field of laser cutting, and in particular to a tube detection auxiliary system for laser cutting equipment. Background Art
[0002] The laser cutting machine focuses 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 its melting point or boiling point. At the same time, high-pressure gas (such as air, nitrogen, and oxygen) coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a cut is eventually formed in the material, thereby achieving the purpose of cutting.
[0003] At present, in the process of cutting metal pipes, it is impossible to judge the material properties of the pipes (when the pipes are difficult to cut, if air or nitrogen is introduced, it will be difficult to cut and the efficiency will be low. Oxygen must be introduced to facilitate the cutting of the pipes). Therefore, each time the pipeline is supplied with gas, it is not accurate. Basically, it is based on the operator's experience to decide which gas to introduce, resulting in low efficiency in pipe cutting. Secondly, during the laser cutting process of the pipe, the molten or vaporized metal is blown away by the high-pressure gas to form metal particles or steam. The metal particles or steam will not only pollute the working environment and have an adverse effect on the air quality, but if the metal particles come into contact with the power supply or high-temperature components, it may also cause a fire or short circuit. Finally, long-term inhalation of metal particles or steam will damage the operator's respiratory system. Summary of the invention
[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art and propose a laser cutting equipment pipe detection auxiliary system to solve the problem in the above technical solution that when cutting metal pipes, the material properties cannot be accurately judged, resulting in the gas selection relying on the operator's experience, thereby reducing the cutting efficiency. At the same time, the metal particles or steam generated during the laser cutting process will pollute the environment, affect the air quality, and may cause safety hazards. Long-term inhalation will cause damage to the operator's respiratory system.
