Ⅱ.Equipment USE of Hydraulic Three-Roll Symmetrical Plate Rolling Machine of Metallurgy Machine
The plate rolling machine is mainly used for bending metal sheet, a kind of general equipment, can complete the prebending of the end face of the plate, can be rolled round, arc and some conical workpiece Angle range, in petroleum, chemical industry, boiler, hydropower, shipbuilding, industrial equipment installation and machinery manufacturing industry has a wide range of applications.
The up and down movement of the upper roller adopts hydraulic transmission. Through the hydraulic pump and cylinder to achieve the straight line movement of the roller, is characterized by stability, automatic oil return when overload, maximize the protection of the equipment; When rolling the cone, the upper roll can be adjusted at will. Compared with the manual pressing down the rolling machine, it improves the efficiency and reduces the labor intensity. It is suitable for the large workload of the rolling project.
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
