Precision
All the steel parts required are produced on modern CNC machinery to ensure consistent within tolerance results. Pivot points for the connection of the swing arm system, hydraulic cylinders, the yoke, utilize high static load bearings and (self-lubricating bushings), being virtually maintenance free.
Encoders are attached to each end of the pinch side rolls, these encoders are used to individually monitor each pinch side rolls position and paralessism relative to the top roll. The encoders operate in unison with the machines PLC and electro-hydraulic valving.
The PLC receives inputs from the encoders, recognising the actual position against a required position, the PLC sends a control voltage to the electro-hydraulic valve(s), the electrovalving then is activated to adjust the hydraulic oil flow to the pinch side rolls to maintain or move to a desired DRO or CNC axis position.
Power
Extensive studies on the materials used and their dimensioning ensure that the Roccia plate rolls can never be thrown into crisis, even when they perform the toughest jobs. Increased structural sections, high driving torque and thrust of bending rolls and strong and efficient support of the machine yoke, these expedients guarantee a greater rigidity of the machine during cone rolling process.
Smart Machines
With the op.time technology Roccia Rundbiegen plate rolls offer up to 20% of energy saving, when compared to traditional plate rolling machines. Our plate rolls use a friction free swing arm system to position the pre bend rolls, no friction, no power absorbed. When the machine is not in use for a period of 5 minutes an electronic control sets the machine into a “stand by mode”.
