Sheet Metal Roller Bender Maintenance
Metal Roller Bender adopts the overall structure. Its design is reasonable and rigid, easy to disassemble and repair.
How to maintain CNC Sheet Metal Rollers?
Routine maintenance of CNC rolling machine tools as follows:
Lubrication
Check the level and quantity of lubricating oil and replenish it in time. Observe whether the hydraulic pump works properly (starting, oiling and stopping on time) and whether the lubricating points of the guide rail have lubricating oil outflow when oiling.
X, Y, Z axis and rotary axis guide rails
Eliminate debris, cutting fluid and other impurities on the guide rail surface.
Check whether the lubricating oil of the guide rail is sufficient, whether there are scratches and rust spots on the guide rail surface, and whether there are iron scraps on the dust-proof scraper of the guide rail.
If it is a rolling slider guide, the user should check the metal rolling slider when scratches occur on the guide.
Compressed air source
Check whether the air supply pressure is normal. Pay attention to timely drainage of air compressor.
Gas-liquid Converter and Supercharger
Check the height of oil storage surface and timely refueling.
Spindle box with lubricating constant temperature oil tank
Make sure the thermostatic tank is working properly. Determine whether there is lubricant according to the oil mark on the spindle box. Adjust the refrigeration temperature of the tank to start normally. Refrigeration temperature should not be lower than room temperature too much (difference is about 2℃ ~5℃). Otherwise, the spindle tends to produce air moisture.
Sheet metal roller bender hydraulic system
Oil tank and hydraulic pump have no abnormal noise.
Pressure gauge indicates normal pressure.
The working surface of the tank is within the allowable range.
The back pressure of the return oil line should not be too high.
There is no leakage and obvious vibration in the pipe joints.
Hydraulic Balance System of Spindle Box
No leakage in the balanced oil circuit.
Balanced pressure indicates normal.
When the spindle box moves up and down rapidly, the pressure fluctuation is not large.
Oil line refueling mechanism operates normally.
Numerical control system input and output
All plate bending rolls CNC devices start normally.
Various electrical devices and cooling ventilation devices
The intake and exhaust fans of numerical control cabinet and metal roller machine tool electrical cabinet work normally.
There is no blockage in the air duct filter.
Ensure that the main shaft motor, servo motor, cooling duct, constant temperature oil tank, hydraulic oil tank cooling radiator ventilation, everything is normal.
All kinds of protective devices
Rails and machine tool shield should be sensitive to action.
For the guard railings, machine work area guard, check that the door’s switch should act normally.
