SAHINLER 4R HS 20-190

Description

• 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 capacities
• Dual rolling speeds Hydraulic balancing system for rolls parallelism

Spec Sheet

• 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.
