Electrical safety and protection of fiber laser cutting machine

The main functions of the fiber laser cutting machine numerical control system are as follows: (a) It should be able to cooperate with CAD/CAM automatic coding: (b) Support RS-274G international standard code numerical control programming: (c) Support automatic program generation of AutoCAD drawings: ( d) Support the automatic adjustment of the distance between the workpiece by the laser cutting head: e) Support the slope adjustment control of the laser output power: (f) Support three-axis linkage and tool compensation, backlash compensation function: (g) Each control There should be a database of pipe cutting experts in the system. The radiation safety and protection of the laser of the pipe cutting machine should comply with GB7247. (a) Each laser product must be equipped with a protective cover to prevent personnel from contacting more than Class 1 A EL laser radiation (including drift laser radiation). (b) Must be a protective cover The bezel provides a safety interlock. (C) The laser system must be equipped with a remote control interlock connector. (D) The laser system must be equipped with a key-operated master switch. 'Keys' include control devices, such as password systems. (E) After the laser system is switched on, there should be audible or visible laser radiation emission warning. (F) The laser system must have one or more additional attenuation devices to prevent people from being exposed to laser radiation. (g) Each laser product must be equipped with a control device to ensure that it will not be exposed to laser radiation during adjustment and use. (j) During the use, maintenance or overhaul of laser products, the mark must be fixed according to its purpose, and the writing must be clear and visible. (h) The laser system should be protected against other non-optical hazards, such as electrical damage, excessive temperature, flame spread in the equipment, sound and ultrasonic waves, harmful substances, explosions, etc.

Fiber laser cutting machine The electrical safety and protection of the tube cutting machine laser should comply with GB10320, (a) The circuit or component electrically connected to the power grid, with a clearance of 3.5mm and a creepage distance of 4.5mm. (B) A stable state is reached after 4 hours of normal operation, and the temperature rise of any part of the equipment shall not exceed the allowable temperature. (C) Insulation resistance test, the insulation resistance measured when 500Vdc is applied between the power circuit wire and the protective grounding circuit, should not be small (d) Voltage insulation strength test, the insulation between the power circuit or component and the equipment casing, Gradually increase to 2000Vac and hold for 1 min. There should be no flashover or breakdown. (e) Leakage current test. The equipment should be placed on an insulating base and work with 1.1 times the rated power supply voltage. The temperature tends to be stable. Impedance test, let the rated current pass through the protective conductor terminal or grounding contact, or one by one to each contact metal.
