Safety Operating Regulations for Fiber Laser Cutting Machine
1. The fiber laser cutting machine should be operated by a dedicated person, and when operated by multiple persons, a main operator must be appointed.
2. Strictly implement the following startup sequence for gas opening: close the discharge valve of the gas storage tank, turn on the power supply of the air compressor, and when the pressure of the compressed air meets the requirements, open the valve of the gas delivery pipeline. Turn on the premixed gas of the laser and adjust the pressure; if the gas of the non-Panasonic laser is mixed in the machine, please turn on the various gases in strict accordance with the following sequence: helium → carbon dioxide → nitrogen, and set the pressure of each gas to the specified value . Turn on the auxiliary cutting gas (nitrogen and oxygen). When using bottled gas, first open the valves of each bottle, and finally open the total valve switch; when using liquid gas, after opening the valve, you should also open the booster valve to increase the vaporization volume to ensure the pressure of the cutting assist gas. Turn on the main power switch and start the stabilized power supply, check the output voltage of the stabilized power supply, and set the voltage between 390~400V. Turn on the power of the chiller and dryer. Turn on the power of the machine control cabinet, release the emergency stop button and turn on the key switch. After the CNC system starts, enter the operation interface. When turning on the power of the machine control cabinet, the laser power can be turned on, and the low voltage and high voltage can be activated in turn. And turn the 'mode selection' key switch to the external control mode. Strictly implement the following shutdown sequence and the preparatory work before shutdown. First move the cutting head to a higher point, and stop the X and Y axes at a safe position. Swap the workbench or stop at a safe location. Turn off the high voltage of the laser, turn off the low voltage of the laser, wait for about 3 minutes and then turn off the main power of the laser (Rofin laser can turn off the laser power immediately. Turn off all the key switches on the laser cabinet and remove it for storage. Press the emergency stop button on the machine control panel side and turn it off Key switch, remove the key for storage. Exit the operation page of the CNC system, and turn off the power of the main control cabinet of the machine tool when the page prompts that you can turn off the power. Turn off the power supply of the chiller and the dryer. Turn off the stabilized power supply. Turn off all cutting aids Turn off the laser gas after the gas. Turn off the air compressor power supply and open the gas tank discharge valve. 1 During the cutting process, the pressure changes of various cutting auxiliary gases should be observed at any time, when the pressure of low pressure gas is lower than 2bar and high pressure nitrogen is lower than 10bar The gas source should be replaced immediately. When replacing the gas source, the gas source valve should be closed and then the gas pipe should be disassembled.
If the gas source bottle is mixed with air, it should be vacuumed first and then filled with the required gas Source. When loading and unloading sheets, use appropriate spreaders and tools to ensure the safety of personnel and equipment. Before cutting, confirm the thickness and material of the workpiece, select the appropriate cutting nozzle diameter, lens specifications, and focus positions. Appropriate auxiliary gas and gas pressure. The cleanness and flatness of the processed sheet must be ensured. The operator should refuse to process the severely rusted and poorly flattened sheet. Test cutting should be carried out before batch cutting. According to the test cutting The effect is to correct the cutting parameters appropriately, and then perform batch processing after the cutting is normal. During the operation of the machine, the operator must not leave the machine tool, and it must be ensured that an operator can monitor the running status of the machine tool at any time. If an abnormal situation occurs, please stop it urgently to eliminate the problem. Production can continue afterwards. The machine tool must be kept clean. The operator must maintain and clean the machine tool every day before leaving work. The transmission and guide rails must be cleaned and lubricated every quarter. The water quality of the chiller water shall be checked every quarter; the machine tool has not been used for a long time. When turning on the machine after cutting, check the air and water paths first, and change the water for the chiller if necessary. Note for machine tool operation: Before executing the machine tool, make sure that all axes have returned to the reference point.
During the maintenance process of the machine tool of the fiber laser cutting machine, it is necessary to ensure that the power supply is in the power-off position and supervised by a special person to prevent accidental closing. Before cutting, the height of the plate should be observed first, and the plate should also be considered For thermal deformation during processing, assign the total height value to the plate thickness parameter of the CNC system. d. After the starting point of the part is set, according to the size of the plate required by the part in the program, run the X axis and Y axis to the specified value. Fixed value to prevent the cutting head from exceeding the contour range due to the tilt of the plate position. The operator should not look directly at the laser flame during the cutting process to prevent burns to the eyes.
The fiber laser cutting machine is not operated by machine tools in the cutting processing area Personnel are not allowed to enter, and no machine buttons are allowed to be touched during processing. In the process of replacing the laser gas, you must pay attention to the transmission pipeline corresponding to the gas. Never connect the gas wrongly, otherwise it will cause serious laser failure. Every time. After replacing the cutting nozzle, you need to check according to the instructions Check and adjust the center of the cutting nozzle. Calibrate the height of the cutting nozzle regularly. Pay attention to the temperature of the output water of the chiller at any time. If it does not meet the requirements, please stop and check immediately. Regularly check the cleanliness of the reflector lens and focus lens. Once contaminated, please clean it immediately according to the prescribed procedures.
