3000mm x 50mm (10’ x 2”) mg
3-roll hydraulic plate bending machine
planetary pinch pyramid plate pre-bending
RATED CAPACITY (cold rolling of plates)

-Width of plate: 3000 mm
-Thickness of plate rolling: 50 mm
-Pre-bending thickness 40 mm
-Total electric power 50 Hp
-Nominal capacity 50 mm thickness on plate yield strength 265 Mpa ( psi 38500 )
-Reducing plate width 1500 mm the rolling capacity is increased up to thickness 65 mm
-Minimum bending diameter ID 580 mm obtainable with medium plate thickness.
Rolls dimensions: -Surface length mm. 3100 -Upper roll dia. mm. 510
-Side rolls dia. mm. 490

Features included:
-Hardening of the 3 rolls. High surface resistance 54/58 Hrc.
-Conical bending attachment with hydraulic angular tilting of side rolls and hardened sliding insert.
-3 rolls driven hydraulic motorized with axial planetary gear unit independent on each roll.
-Digital readout on lower rolls positioning.
-Nr. 2 (1 left side/1 right side), dual articulation arm hydraulic operated capacity 2,8 Ton
-Nr. 1 Central support of plate being rolled hydraulic operated capacity 2,5 Ton -ID max 3000 mm

General specifications:
-Parallelism between top and bottom rollers with massive torsion bar on each roll.
-The 3 rolls installed on self aligning double crown floating barrel bearings.
-Greasing free technology with sealed bearings and self lubricated bushings.
-Centralized control panel movable on wheels for easy one-man operation.

General construction details.
-3 rolls plate bending machine with pinch pyramid plate pre-bending configuration.
-No turning of plate is required all along the rolling process. Easy one-man operation.
-Machine housing and frames made of welded steel construction.
-Parallelism between top and bottom forming rollers guaranteed with massive torsion bar on each roll.
-Forming rollers with planetary motion hydraulically operated with adjustable pre-pinching pressure for the deflection compensation
of rolls crowning to achieve best plate pre-bending of leading and trailing edges.

-Rotation of rolls powered with independent hydraulic motor and axial planetary gear reduction unit each roll. Total torque
transmission to the plate being rolled with automatic hydraulic speed compensation system to ensure transverse forces acting on
both surfaces of the plate eliminating sliding of the plate while rolling.
-Front opening ( drop-end) hydraulic operated to open the front support of the top roll for removal of the formed plate.
-The rolls are installed on self aligning double crown floating barrel bearings pre-greased and factory sealed.
Protection and safety arrangements.

-Overload protection relief valves on each single hydraulic movable part on the machine.
-Hydraulic limit switches ( relief valves) to stop the roller at their end position.
-Automatic hydraulic instant braking of rolls rotation.
-Emergency shut-down system by means of electric safety push buttons.
-Perimeter protection all around the machine with safety wire operating power shut-own.
Hydraulic unit.

-A single centralised hydraulic tank self enclosed on the rear frame of the machine provides the oil feeding for all the bending
operations through independent pumps to power simultaneously the rolls rotation and the bending movements of forming rolls.
-All the movable parts are controlled with direct drive solenoid hydraulic valves operated from remote console.
Electric unit.
-Single centralized electric motor standard star/delta start, to run the pressure hydraulic pumps.
-Complete electric control of the machine from a single centralised console to accommodate the best working position.

Lubrication and greasing.
-Greasing free technology. All parts pre-greased and sealed in the factory. High efficiency components with reduced maintenance.

Components and parts manufacturer.
-All the commercial components electric, hydraulic, bearings, pumps, valves, are of first quality European manufacturer.
-Input power supply 3 phase Vac to be provided by user up to the machine.
-Hydraulic oil ISO grade 32. ( oil not supplied )
-Water supply not required.
-Air compressed supply not required.
-Foundation drawings at order time.

-1 Sets of operation and maintenance manuals will be provided along with the machine.
-Manuals consists of the following :
-Instructions for operating the machine with sequence process description.
-Instructions for proper maintenance of the machine, including service charts.
-Safety instructions during operation and maintenance of the machine.
-Electrical/electronic circuit diagrams and wiring diagrams with parts identifications.
