ITEM: 8' x 1/2" Hydraulic 3-Roll Double Pinch Plate Bending Roll
MODEL: PRH-8-280 (3R HS 25-280)
Product Features
Fully hydraulic
Compact design for minimal floor space
Welded, thermally stressed relieved, all steel frame and drop end
3-Roll Drive: All three rolls are driven and directly connected to a hydraulic motor through a planetary gearbox from a central hydraulic power system
Orbital movement of the side rolls for faster rolling and easier prebending of light to medium capacities
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
Dual rolling speeds
Each lower roll hydraulically and independently adjustable, providing double prebending of both the leading and trailing plate edges with one insertion of the plate into the machine
Balancing system for rolls parallelity
Robust drop end; hydraulically operated
Operating controls and 2 electronic digital readouts for the positions of the lower rolls in a rolling control console, each with programmable roll position pre-set and memory
Cone bending attachment is standard equipment; and the lower rolls can be individually tilted for more effective cone rolling, after which they can be easily paralleled for normal rolling
Roll shafts are extended beyond the end frame to accept optional bar/angle and pipe rolls
Extra-large openings between the upper and lower rolls to accept thick, narrow plates and even some structurals
All the advantages of initial-pinch, pyramid and double pinch rolling
Pre-arranged for easy retro-fit of overhead and side support devices if required after machine has been put into operation
Components are from world renowned sources: Telemecanique, NAIS or Siemens for electrics; Rexroth, Bosch, Parker or Duplomatic for hydraulics; SKF or FAG for bearings
Built according to stringent European standards for design, production and quality and bearing the CE Mark of certification
*With prebending, resulting flat ends are rated at 2 to 2-1/2 times plate thickness or less. Proportional capacities in other material, widths and thickness and to other diameters. Cone bending capacity is 50% of each the length and thickness capacities
3-Roll Drive
The complete hydraulic system with motor and controls
Induction Hardened and Crowned Rolls
Orbital movement of the side rolls
Two Electronic Digital Readouts
Mobile Control Console: Operating controls in a rolling console for all functions including tilting the lower rolls (for cone rolling) and paralleling them thereafter, and for operation of the drop end
Cone Bending Attachment
Central Lubrication System
Electric motor and controls. Electrics for 3/60/22/440 (other voltages on request)
Low voltage at the controls
Extended shafts for optional bar, angle, pipe, tube and shape rolls
Emergency stop wires at the front and rear of the machine and emergency stop button in the control console
