Description

6′ x 1/4″ New Cole-Tuve Four Roll Plate Bending Roll Model 4R HS 20-150 (Hydraulic Double-Pinch Plate Bending Rolls) Specifications:

6′ x 1/4″ New Cole-Tuve Four Roll Plate Bending Roll Model 4R HS 20-150 (Hydraulic Double-Pinch Plate Bending Rolls) 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 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 pretending of light to medium 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 titled 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 into operation.
• Built according to stringent European standards for design, production and quality and bearing the CE-Mark of certification.
