Ⅱ.Matters needing attention of Hydraulic Three-Roll Symmetrical Plate Rolling Machine of Metallurgy Machine
1. It is strictly prohibited to use hydraulic oil.
2. Overload is strictly prohibited.
3. It is strictly prohibited to run after overlapping of two plate heads (in the case that the height of the upper roll is not adjusted), which is easy to damage the gear and roll.
4. Be careful not to let foreign matter fall into the gear and oil filling port.
5. No feet or hands shall be placed on the rotating workpiece or roll during the rolling operation. No one shall be allowed on both sides of the rolling machine to prevent foreign bodies from escaping and accidents.
6. There must be leakage protection device.
7. When lifting the upper roll, it is necessary to keep a certain distance between the upper roll and the upper limit screw.
8. The oil drum is filled with butter, and then add enough oil in the gearbox, do not disassemble casually.
9. The direction of the motor must be rotated according to the direction indicated.
10. The oil pump motor is prohibited to reverse.
Ⅲ.Fault and the solution of Hydraulic Three-Roll Symmetrical Plate Rolling Machine of Metallurgy Machine
No. | Fault symptom | Possible cause
| Solution
|
1 | Motor shutdown | Overload Out-of-phase | Reduces down pressure on the upper roll
Maintenance |
2 | The workpiece does not go | Motor not running
There is oil dirty in the plate or roll body
Triangle belt over loose | Check the line, motor
Removing oil stains
Adjust the tension of the triangle belt |
3 | Excessive fracture of the upper roller journal | Overload, excessive pressure
Violation of operating rules
| Pay attention to the amount of pressure
Correct operation
|
4 | The cylinder is not working | The hydraulic motor does not rotate (or the direction is wrong) the hydraulic oil is too little
The relief valve damping hole is blocked | Check motor wiring or steering Fill with hydraulic fluid
Check whether the filter is blocked and remove the damping hole
|
5 | The two ends of the winding workpiece have different radians | The upper roller height is not the same There are foreign bodies on both sides of the rolling workpiece, welding slag, etc The ID of the digital display table is incorrect | Operate the solenoid valve separately
Remove foreign matter and welding slag
Adjust the number display table
|
6 | Couldn't get the slider out Reverse the slide and it won't fall | It's not in the right position
The down roll doesn't work | Adjust
Adjust
