Technical machine configuration:

Rolls length 3100 mm Top roll size mm. 1100 Side rolls size mm. 980

Torque daNm. 155.000 Bending power Tons. 3500 Electric requirement: 400 Hp.

3 rolls driven, powered with hydraulic motor and planetary gear unit each roll.

Rolling speed variable up to max. 4 mtr./min.

Speed control and compensation: automatic by the hydraulic system.

Rolls movement: fully hydraulic with pistons and hydro-motors.

Pinching operation: hydraulic powered.

Drop-end : hydraulic operated ( opening top roll to unload the formed plate ).

Rollers made out of forged alloy steel with treatment for stress relieve and induction hardening.


Features description:

The lower rolls are positioned independently with planetary pinch against top roll. Parallelism with torsion bar for the best

repeatability and lifetime lasting accuracy. The 3 rolls are hydraulic driven, each one powered with hydro-motor and axial gear unit

to guarantee a perfect total torque transmission to the plate. The speed of revolution is controlled with an automatic hydraulic

peripheral compensation to avoid plate slippage.

The planetary pinch configuration allow to obtain an optimal pre-bending leverage condition against the plate being formed, thus

reducing the remaining flat. The edge of the plate can be clamped on the extreme end, very much close to the pinching position

without having slippage. This is resulting a simple process and accurate pre-bending of the plate ends.

Opening gap between rolls is very large, much above that the nominal capacity of the machine, this is giving the additional

advantage to roll specific applications. The lower rolls can be tilted for cone rolling fully hydraulic operated with digital position

reading. Can be formed a very tight diameter of the cone.

General description:

-3 rolls hydraulic plate bending machine with dual pre-pinch planetary pyramid configuration

-The rolls are crowned to compensate the loads for deflection and increase the gripping power between plate and rolls.

-No turning of plate is required all along the rolling process. Easy one-man operation.

-Parallelism between top and bottom rollers with torsion bar system lifetime lasting accuracy.

-Machine housing and frames made of welded steel construction and stress relieved.

-The 3 rolls installed on sealed bearings , free from greasing and reduced maintenance.

Protection hydraulic and safety features:

- Hydraulic peripheral speed compensation system between top roller, plate and bottom roller.

-Hydraulic system with relief valves to stop the roller at their end position.

-Automatic hydraulic instant braking of rolls rotation

-Overload protection valves on each hydraulic movable part on the machine.

-Emergency shut-down system by means of electric safety equipments and push buttons.


Hydraulic unit:

-A single centralised hydraulic tank enclosed on the rear of the machine provide the oil feeding for all the bending operations.

-The unit is powered with independent pumps to feed simultaneously the rolls rotation and the bending movements of forming.

-Rolls movement controlled with direct drive electric solenoid valves.

Electric unit:

- powered with electric motors standard star/delta start, to run the pressure hydraulic pumps.

-Commands to the machine are given from a centralised electric console movable on wheels and remotable

to accommodate the best working position. The console is provided with digital readout of rolls bending positions.

Lubrication and greasing:

-Greasing free technology. All parts pre-greased and sealed in the factory. Very limited periodical maintenance requirement.
