1. Strictly adhere to the machine tool safety operating procedures and wear appropriate personal protective equipment as required.
2. Before starting, carefully check that the motor, switches, wiring, and grounding are normal and secure. Check that all operating parts and buttons are in the correct positions.
3. Check the overlap and firmness of the upper and lower dies; check that all positioning devices meet the requirements of the workpiece.
4. When the upper slide and all positioning axes are not at their origin, run the return-to-origin program.
5. After starting the machine, run it idle for 1-2 minutes, allowing the upper slide to complete its full stroke 2-3 times. If any abnormal sounds or malfunctions are detected, stop the machine immediately, troubleshoot the problem, and only resume operation after everything is normal.
6. During operation, one person should provide unified command, ensuring close coordination between the operator and the feeding and pressing personnel. Ensure all personnel are in safe positions before issuing a bending signal.
7. The sheet metal must be firmly pressed during bending to prevent it from warping and causing injury.
8. Power must be disconnected and the machine stopped before adjusting the sheet metal pressing die.
9. When changing the opening of the variable lower die, no material is allowed to come into contact with the lower die.
10. No one is allowed to stand behind the machine tool while it is operating.
11. It is strictly forbidden to press and bend sheet metal at only one end.
12. If the workpiece or die is found to be misaligned during operation, the machine should be stopped and corrected. Correction by hand while the machine is running is strictly prohibited to prevent hand injury.
13. It is forbidden to bend excessively thick iron plates, quenched steel plates, high-grade alloy steel, square steel, or sheet metal exceeding the performance limits of the sheet metal bending machine, to avoid damaging the machine tool.
14. Regularly check the overlap of the upper and lower dies; ensure the pressure gauge readings meet specifications.
15. If any abnormality occurs, stop the machine immediately, investigate the cause, and eliminate it promptly.
16. Before shutting down, place wooden blocks on the lower die below the cylinders on both sides to lower the upper slide onto the blocks.
17. Exit the control system program first, then disconnect the power.
