Description

Model: 4RS-13-280
Capacities based on steel up to 40,000 PSI yield strength:
* Circular bending to diameters 5 times upper roll dia and
larger .............. 13' X 5/16"
* Circular bending to diameters 1-1/2 times upper roll
diameter and larger . 13' X 1/4"
* Prebending to diameters 5 times upper roll diameter and
larger .............. 13' X 1/4"
* Prebending to diameters 1-1/2 times upper roll diameter
and larger .......... 13' X 5/32"
(With prebending, resulting flat ends are 1-1/2 to 2 times
plate thickness or less. Proportional capacities in other
material, widths and thicknesses. Cone Bending capacities
50% of each length and thickness capacities.)

FEATURES:
* Four roll design and construction. Compact design for
minimal floor space. Welded, all-steel, heavily
proportioned, thermally stress-relieved frame and drop-end.
Roll shafts journalled in self-lubricating bronze and
spherical roller bearings. Induction-hardened SAE 1050
steel bars, hardened to 55-58 Rockwell C are used for the
rolls. Rolls are precisely machined wtih crowning to
compensate for deflection under load.
* Fully-Hydraulic:
Three-roll drive: The upper central and each of the two
side bending rolls are driven, each by a hydraulic motor
through a planetary gearbox from a central hydraulic power
system.
* The lower central roll and the two side bending rolls are
hydraulically and individually adjustable and tiltable.
Each side roll is adjustable hydraulic and independently to
provide double pre-bending; therefore each end of the
workpiece can be prebent and then rolled with only one
insertion of the workpiece into the machine.
* Linear movement (slide) of the side rolls for more
powerful and efficient rolling of medium to heavy
capacities.
* Dual rolling speeds.
* Balancing system for roll parallelity.
* Robust drop end, hydraulically operated.
* Controls for all functions and electronic digital readouts
in a rolling console.
* Cone bending attachment is standard equipment; and the
side rolls can be tilted for more effective cone rolling,
after which they can be easily paralleled for normal
bending.
* All the advantages of asymmetrical, pyramid and double
pinch bending.
* 3-Electronics digital readouts (LED) for the positions of
the side rolls and the lower roll, each with programmable
roll position pre-set and memory.
* Components are from world-renowned sources. Hydraulics by
Rexroth, Bosch, Duplomatic or Parker. Electrics by Siemens,
NAIS, or Telemecanique. Bearings by FAG and SKF.
* Pre-arranged for easy retro-fit of overhead and side
support devices if requi
