COLE-TUVE 4R HSS 30-280 Four-Roll Double-Pinch Hydraulic Plate Bending Roll 10 ft x 1/2"

• 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 and bronze bushings
• 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
• Three-roll drive. The upper central roll and the two side rolls are driven from a central hydraulic power system, each roll by a hydraulic motor and planetary gearbox
• The lower central roll and the two side 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
• The top roll tilts up when the drop end goes down to easily remove the rolled material
• Linear movement of the side rolls (with hydraulic pistons) for more powerful and efficient rolling of medium to heavy capacities
• 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
• 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 machines has been put into operation
• Built according to stringent European standards for design, production and quality and bearing the CE-Mark of certification

STANDARD EQUIPMENT:

• Three-roll drive. The upper and lower side rolls are driven by hydraulic motor through a planetary gearbox.
• Induction hardened and crowned rolls
• Hydraulic adjustment of the lower central roll and of the side rolls, each independently
• Hydraulic drop end for easy removal of the completed cylinder
• Hydraulic system complete with controls
• Linear movement (slide) of the side rolls
• Dual rolling speeds
• Balancing system for parallelism of the rolls
• Manual central lubrication
• Cone bending attachment
• Operating controls in a rolling console for all functions including adjustment of the lower and side rolls, for paralleling and tilting side rolls (for cone rolling) and for operation of the drop end.
• 3 - Electronic digital readouts (LED) for the positions of the side rolls and the lower central roll 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.
• Electrics by Siemens, NAIS or Telemecanique
• Bearings by FAG and SKF
• 2 - Operating Manual/Parts List
