1. During the bending process, it is important to be quick and coordinated, maintain focus, and ensure that personnel not involved in the operation do not stand near the machine.
2. When loading materials, hold the workpiece correctly:
2.1. The thumb should be above the material, while the other four fingers should be below the material.
2.2. For processing smaller workpieces, use pliers instead of hands to grip the workpiece.
3. When bending longer workpieces, avoid extending the head, chest, or other body parts above the workpiece to prevent injury if the workpiece springs up.
4. For bending thicker plates above 2.5mm and wider or longer workpieces, the bending speed should not be too fast. Ensure that the upper and lower dies come together slowly to prevent damage to the dies and ensure personal safety.
5. For bending thinner and smaller workpieces, maintain a slow speed to prevent deformation due to inconsistent coordination between the operator and the machine.
6. When processing arcs, select the appropriate die based on the radius (R). The lower die can use a "V" groove slightly larger than the arc. When using straight or pointed tools for forming, ensure that the distance between bending sections is not too long to avoid obvious tool marks on the workpiece surface.
7. The minimum angle for edge pressing should not be less than 40 degrees.
8. During sample processing, a test bend with scrap material must meet the drawing requirements before actual forming. Any process issues affecting the current operation should be documented and reported to the relevant project engineer.
9. During forming, process the product in the sequence of "cover first, bottom later," and ensure coordination during processing. If difficulties arise due to angle, size tolerances, bending deformation, etc., a designated team should handle corrections.
10. While the machine is operating, it is strictly prohibited to reach under the die from the front of the machine to adjust rear positioning gauges or to maintain the machine.
11. Control the lower limit position of the upper and lower dies appropriately during work. Ideally, the workpiece should be easily removed after bending. Adjust bending speed rationally; generally, start slowing down when the upper die is 2-5mm away from the workpiece bending surface for safe and efficient operation.
12. Maintain a clean work environment and clear workshop aisles. Do not place any objects near firefighting equipment or block fire exits.
