Description

ITEM: 8' x 3/8" Hydraulic 4-Roll Double Pinch Plate Bending Roll
MAKE: COLE-TUVE®
MODEL: 4RS-8-245 (4R HS 25-245)
Product 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 with crowning to compensate for deflection under load
Fully hydraulic
The upper central roll is driven by a hydraulic motor through a planetary gear box 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 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 for faster rolling and easier prebending of light to medium capacities
Dual rolling speeds
Hydraulic balancing system for rolls parallelity
Robust drop end, hydrically 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 into operation
Built according to stringent European standards for design, production and quality and bearing the CE mark of certification
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 length and thickness capacities
STANDARD EQUIPMENT
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
Orbital movement of the side rolls
Dual rolling speeds
Hydraulic balancing system for parallelity 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 (for cone rolling) the side rolls 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-se
