Plate rolling machine is very important in mechanical processing, so how to use plate rolling machine correctly? What problems may be encountered during the operation of the bending machine? Mingcheng Electromechanical Equipment Co., Ltd. will tell you about the operating precautions of the three-roller bending machine. I hope to compare my usual operations to see if there are any problems. If there are, correct them as soon as possible. If not, congratulations, your coil The operation of the machine is very correct!

Problems that may be encountered in the operation of the rolling machine:

1. 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.

2. Check whether the oil storage tank of the hydraulic station is sufficient before using the bending machine. Start the hydraulic station to check whether the oil pump is working properly, whether the valve and pipeline are leaking, and the pressure value does not meet the requirements, open the air release valve to release the air in the system.

3. It is not allowed to work when the steel plate is bent, or the oil pressure of the hydraulic station is unstable or the oil temperature and bearing temperature exceed 60°C.

4. Steel plates with raised weld seams or cutting burrs should not be rolled or leveled.

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

6. When rolling or leveling, make sure that the steel plate and work roll cannot slip.

7. The operator and other staff should cooperate closely. Obey the command of a special person, and the command signal must be clear.

8. When rolling a conical workpiece, the small round end of the workpiece should be pressed on the guide roller of the vertical roller.

9. When using cushion blocks to level the steel plate, the hardness of the cushion blocks shall not be higher than that of the work roll.

10. When rolling the steel plate with the maximum thickness, the ratio of the radius of the finished product after the first reduction to the minimum radius of the finished product must not be less than 2. It is then applied to the minimum finished radius required for 2~3 times of winding.

11. When the workpiece is still clamped between the upper and lower work rolls, the turning mechanism shall not be activated to turn the overturned beam. Only when the lower work roll stops rotating and the workpiece falls away from the upper work roll, can the turning mechanism be activated to turn the overturned beam. Only after the overturned beam is disengaged from the upper release bearing, can the upper work roll be tilted.

12. Except the throttle valve, other hydraulic valves are not allowed to adjust without permission.

Now everyone knows what are the precautions for the operation of the plate rolling machine!
