Precautions and steps for using the bending machine

1. Before using the bending machine, check whether the oil volume in the oil tank of the hydraulic station is sufficient. Start the hydraulic station to check whether the oil pump works normally, whether there is leakage in valves and pipelines, and whether the pressure value reaches the requirements. Open the vent valve to drain the air in the system.

2. Steel plates with protruding welds or cutting burrs shall not be rolled or leveled.

3. During coiling or leveling, pay attention to that the steel plate and the work roll shall not slip.

4. When rolling the conical workpiece, the small round end of the workpiece shall be pressed on the guide roller of the vertical roller.

5. When leveling the steel plate with the cushion block, the hardness of the cushion block shall not be higher than that of the work roll.

6. During coiling or leveling, the steel plate shall be placed in the middle of the work roll, and the thickness of the steel plate shall be reduced accordingly during offset.

7. When rolling steel plates with large thickness, the ratio of the radius of rolled products to the radius of small products to be rolled shall not be less than 2. It is then applied to the small finished product radius required for 2~3 times of winding.

8. Do not work when there is overlap in the steel plate bending, and do not work when the oil pressure of the hydraulic station is unstable or the oil temperature and bearing temperature exceed 60 ° C.

9. When the workpiece is still clamped in the upper and lower working rolls, the turnover mechanism shall not be started to turn over the beam. Only when the lower work roll stops rotating and the workpiece drops off the upper work roll can the turnover mechanism be started to turn over the beam. The upper working roll can be tilted up only after the overturned cross beam is disconnected from the upper off bearing.

10. When removing the workpiece, prevent the oxide skin and dust from falling into the bearing of the overturned beam.

11. Except for throttle valve, other hydraulic valves shall not be adjusted without permission.

12. The operator shall work closely with other staff. Follow the command of the specially assigned person, and the command signal shall be clear.
