1. When the roll forming machine rolls the conical workpiece, press the small round end of the workpiece against the guide roller of the vertical roller.
2. The steel plate is not allowed to run when the steel plate is bent. When the hydraulic station oil pressure is unstable or the oil temperature and bearing temperature exceed 60°C, it is not allowed to work.
3. During rolling, no slippage is allowed between the steel plate and the work roll; when rolling or leveling, the steel plate should be placed in the middle of the work roll, and the thickness of the steel plate should be reduced accordingly when offset.
4. When the steel plate is flattened with pads, the hardness of the pads should not be higher than that of the work rolls, and care must be taken not to roll or flatten the protruding welds or cut edge steel plates.
5. Before starting the roll forming machine, check whether there is any abnormality in each part, the tightening nut should not be loose, the brake should be normal and reliable, and the reel distance should be adjusted strictly according to the thickness of the plate. Workpieces within the performance specification.
6. During operation, the workpiece must be placed stably, and the vehicle can only be operated after it is in the correct position. The signal should be clarified and a person should be assigned to direct it.
7. When the roll forming machine is running, the hand cannot be placed on the rolled steel plate, nor can it be checked with the sample plate, and the roundness can be checked with the sample plate after the machine is stopped. When rolling a workpiece that is not round enough, a certain margin should be left when rolling to the end of the steel plate to prevent the workpiece from falling and hurting people.
8. When the roll forming machine is working, it is forbidden to stand on the workpiece, and it is not possible to find the roundness on the rolled cylinder.
9. Cylinders with thick rolls and large diameters or workpieces with high material strength should be rolled down and rolled for many times. When rolling a narrow cylinder, it should be placed in the middle of the roll for rolling.
10. After the workpiece enters the roll of the roll forming machine, hands and clothes should be prevented from being involved in it.
11. If the machine tool is found to have abnormal noise after the machine is stopped, it should be checked and repaired immediately. After the machine is stopped, the workpiece should be placed in the designated place.
