Press Brake Safety Operating Procedures

Safety Operating Procedures

1. Strictly adhere to the safety operating procedures of machine tools and wear protective labor equipment as prescribed.
2. Maintain a clean surrounding of the press brake machine, remove any obstructions, ensure the ground isn’t slippery, and immediately address any oil leaks to prevent slip hazards.
3. Before starting, thoroughly check the motor, switches, circuits, and grounding for proper function and security. Ensure all operational parts and buttons are in the correct positions.
4. Inspect the alignment and sturdiness of the upper and lower molds, and ensure positioning devices meet processing requirements.
5. When the sliding board and positioning axles are not at the original position, run the return-to-origin program.
6. After starting the equipment, let it run empty for 1-2 minutes, with the sliding board completing its full travel 2-3 times. If any abnormal noises or malfunctions are noticed, stop immediately, resolve the issue, and only resume work once everything is in order.
7. While working, a single person should coordinate and command the actions to ensure safety and quality.
8. When bending sheets, apply sufficient pressure to prevent sheets from lifting and causing injuries.
9. When adjusting sheet clamping molds, cut off the power and only proceed once the machine has stopped.
10. When altering the opening of the adjustable lower mold, ensure no material is in contact with it.
11. Keep hands and other body parts away from the working area while the machine is operating. No one should stand behind the machine.
12. Avoid bending sheets at one end only; center sheets on the machine for bending.
13. For every 100mm of bending length, the bending load should not exceed 100KN.
14. If a workpiece or mold is misaligned during operation, stop the machine for adjustments. Never adjust by hand during operation to avoid injury.
15. Do not bend excessively thick iron plates, hardened steel plates, advanced alloy steel, square steel, or any material beyond the machine’s capacity.
16. Regularly inspect the alignment of the upper and lower molds and ensure the pressure gauge reading is in accordance with standards.
17. In case of abnormalities, shut down the machine immediately, identify the cause, and rectify it.
18. Before shutting down, place wooden blocks under the cylinders on the lower mold and lower the sliding board onto them.
19. First, exit the control system program and then cut off the power.

Machine Maintenance and Care

1. Before operation, lubricate all points with calcium-based grease. Add L-HM46 (GB111118.1-1994) superior-grade anti-wear hydraulic oil to the hydraulic system’s oil tank. Change the oil one month after first use; all oil additions must be filtered. Subsequently, change the oil yearly or as needed, maintaining a minimum oil temperature of 15°C.
2. Ensure hydraulic oil cleanliness during extraction, filtering during oil additions. Before adding new oil, clean the hydraulic system thoroughly; don’t mix with other working mediums. After 1000 hours or six months of use for new machines, change the oil, then every 2000 hours or annually thereafter. Maintain strict sealing in the hydraulic system to prevent foreign contaminants like dust, debris, water, or other liquids from mixing.
3. For the initial start-up, run the oil pump motor group without load. Pay attention to the motor’s rotation direction, then test machine functions with “tapping”, followed by “single” and “continuous” actions, as well as the slide travel and rear-stop control capabilities, ensuring the machine operates smoothly.
4. Before using the machine, lubricate it. Carefully identify the lubrication points of the press brake, add lubricating oil, and ensure the press brake is properly and adequately lubricated. When using lubricating oil, mix it with 50% mechanical oil N46.
