BENDING ROLL MACHINE “MG” MOD. AK332E 3 ROLL DOUBLE PINCH PLATE
Standard equipment:
- Compact hydraulic power unit including hydraulic valves and flexible hydraulic hoses
- Electric control cabinet including overload protection for electric motor, electric fuses, electric contacts, electric relays, and security key-lock door
- Special front/pivoting operators console including progressive hydraulic controls for all machine
- Hydraulic machine opening to extract finished cylinders
- Multi-system emergency safety device for instantaneous stopping of all movements.
- Floating control w/electro valves
Features:
- All steel structural welded frame construction (often no foundation required)
- Hydraulic drives with infinitely variable speeds automatically adjusted by progressive controls (hydroelectric valve machines excluded)
- Plate is driven by high-energy efficiency hydraulic motor/planetary drive eliminating secondary reduction gears, chains, synchronization devices and clutches.
- Instantaneous drive stop of rolls by hydraulic over-center valves
- Side-forming rolls controlled by hydraulic cylinders with infinitely variable speed
(hydroelectric valve machines excluded)
- Automatically controlled side roll parallelism mechanical controlled by “TORSION
BARS
- Hydraulic powered drop end
- Automatic balancing of top roll (to open the machine)
- All rolls mounted on SPECIAL floating 2 crowns rolls bearings with automatic self-alignment
- All rolls are cambered to compensate for deflection and to increase the driving and
gripping power of the two central rolls.
- Fully hydraulic powered movements
- One only operator required
Technical data:
Installed power: Kw. 18.5
Top roll diameter: mm. 400
Side rolls diameter: mm. 380
Capacity:
Working length: mm. 3,100
Maximum rolling thickness: mm. 32
Maximum pre-bend thickness:mm.25
Machine size:
Width: mm. 2,030
Total length: mm. 5,235
Working height: mm. 1,435
Weight: Kg. 14,000
The max performances are referred to shells of diameter equal or larger than 3 times the top roll diameter and with material with a yield point within R = 260 N / mm².
Technical characteristics:
A) AUTOMATIC ADJUSTMENT FOR CONE -
movable rolls by MASSIVE MECHANICAL TORSION SHAFTS without any of
the adjustments and re-balancing required by hydraulic leveling systems.
B) ALL PLANETARY MOVEMENTS - Eliminating all friction common to vertical,
diagonal or horizontal sliding guide systems and requiring absolutely no
adjustment.
C) PERMANENT LUBE SYSTEM - No more ordinary greasing and lubrication for
all the life of the machine by specially protected screened and full-life pregreased
components.
C) Replacement of all low efficiency components (reduction unit, high friction
bronze bushings, mechanical drives, gears, belts joined arms, sliding guides,
etc.) by new high energy efficiency drives (planetary gears DIRECT DRIVE
COUPLED to the rolls, bearings, central multi-way electro/hydraulic power
motor) keeping the real force available on the plate to bend (positive power)
Energy saving system conforms to the "International High Efficiency and Anti-
Pollution" rules and standards.
