3. According to different plate thickness and material, re-set the cutting speed and warm-up time in the machine, set the reasonable pressure of preheating oxygen and cutting oxygen.
4. Do not touch the flame area after ignition. Operators should take a small splash cutting method to protect the cutting nozzle.
5. Check the heating flame, and cut the oxygen jet. If it is found that the cutting nozzle is damaged, it should be promptly replaced and cleaned. The cleaning nozzle should be cleaned with special tools.
6. When a flashback occurs during the cutting process, the power supply should be cut off in a timely manner, shut down and the gas valve should be turned off. If the tempering valve piece is burned, it should be stopped and used for replacement by other manufacturers or professionals.
7. When the CNC flame operator operates the cutting machine, it is necessary to pay attention to the operation status of the equipment at all times. If abnormal conditions are found, the emergency stop switch shall be pressed to exit the work position in time and the boot is strictly prohibited from leaving the site.
8. The operator should pay attention that after cutting a workpiece, the torch should be lifted back to its original position, and then cut to the next station.
9. The operator should select the cutting speed according to the provisions of the given cutting elements. It is not allowed to increase the equipment load simply to increase the ergonomics, and the relationship between equipment life and efficiency and environmental protection should be properly handled.
Third, operate the CNC flame cutting machine after work
1. After work, the equipment should be returned to the protection position and the air valve should be closed. The residual gas in the pipe should be drained and the power turned off.
2. If the shift system is implemented, the operation status of the on-duty equipment should be recorded as a shift.
3. The site should be carefully cleaned and the work area should be kept clean and orderly.
Fourth, daily maintenance
1. Track does not allow personnel to stand, step on, rely on heavy objects, but also does not allow impact, the rail surface after each class with compressed air dusting wipe with gauze 20# oil rail surface. At any time to keep the rail surface lubrication, clean.
2. The transmission rack should be cleaned with 20# oil every day, and no spatter on the rack is allowed.
3. The operator is only allowed to disassemble the cutting nozzle, and the remaining parts cannot be disassembled. The electric junction box can only be opened when the relevant personnel are allowed to overhaul.
4. If the equipment fails, it should be promptly requested by the maintenance personnel. When the failure is large, it should be reported to the equipment department to organize the relevant personnel to review and determine the maintenance plan. It is forbidden to disassemble the machine.
Fifth, the operation of CNC flame cutting machine should pay attention to safety and security
1. Strong vibration sources should be avoided around the equipment.
2. Staff members are listed for posts, and irrelevant personnel are not allowed to board the machine, nor are they allowed to press keys without authorization so as to avoid damage to the machine or program and data loss.
3. When moving the equipment, care should be taken not to allow unhooking or pre-shooting. No part of the guide rails on the machine can hit.
4. The device power source line should be used alone, and with AC voltage regulator device.
5. Ventilation or replacement of gas and cleaning torch must be performed in accordance with the relevant dangerous gas safety operating procedures.
