New COLE-TUVE by Sahinler Hydraulic Plate Bending Roll, Model 4R HS 20-190. Four-Roll, Double-Pinch Type.
Capacities based on steel up to 38,000 PSI Yield Strength:
- Circular Bending to diameters 5 times upper roll diameter and larger 6’ x 5/16”
- Circular Bending to diameters 1-1/2 times upper roll diameter and larger 6’ x 1/4”
- Prebending to diameters 5 times upper roll diameter and larger 6’ x 1/4”
- Prebending to diameters 1-1/2 times upper roll diameter and larger 6’ 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 capacity is 50% of each width and thickness capacities.
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 journaled in radial bearings.
Induction-hardened SAE 1050 steel bars, hardened to 58 - 60 Rockwell C are used for the rolls. Rolls are precisely
machined with crowning to compensate for deflection under load.
Fully hydraulic. Two-roll drive. The upper and lower central rolls are driven from a central hydraulic system, equipped
with overload protection, by a hydraulic motor through a planetary gearbox.
The lower central roll and the two side bending rolls are hydraulically and individually adjustable and tiltable.
Each side roll is adjustable hydraulically 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.
Orbital movement of the side rolls (with hydraulic pistons) for faster rolling and easier prebending of light to medium
Dual rolling speeds.
Hydraulic balancing system for rolls parallelism.
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 - Electronic 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.
Pre-arranged for easy retro-fit of overhead and side support devices if required after machine has been put
Built according to stringent European standards for design, production and quality and bearing theCE-Mark of certification
Overall working length of the rolls - 80.7”
Diameters of the upper and lower central rolls - 7.48”
Diameter of each side roll - 5.91”
Rolling speeds, dual - 5 and 19-1/2 FPM
Motor HP - 7
Dimensions, L x W x H, excluding control console - 174” x 42” x 50”
Weight - 7,700#

3 - Electronic digital readouts (LED) for the positions of the side rolls and the lower central roll are mounted
in the rolling control console, each with programmable roll position pre-set and memory.
Electric motor and controls. Electrics for 3/60/220/440. Low voltage at the controls.
Overload and under voltage protection. Emergency stop wires at the front and rear of the machine.
Hydraulics by Rexroth, Bosch, Duplomatic or Parker.
