Character of SL 3 Roller and 4 Roller Plate Bending Machine for Marine and Storage Tank Construction China

1. The 3 roll hydraulic plate rolling machine features linear hydraulic movement of all three rolls: Vertical top roll and horizontal bottom roll movement. This concept offers some significant advantages over other 3 roll concepts regarding pre-bending, bending quality and work-piece handling.

The following basic operations can be used:

• Pre-bending of sheet edges
• Rounding of sheets into cylindrical shapes
• Press bending of cones and cylinders
• Calibrating for minimization of radius variations in a welded tube

The most significant technological leap occurred with the completion of a revolutionary concept. This patented design eliminates some typical industry standard disadvantages of 3-roll machines and allows the operator the best possible view of the bending process, guarantees minimal foundation costs and allows the use of pushing cylinders for all three rolls.

Advantages

• Excellent bending results due to total machine symmetry.
• 42 CrMo rolls are very crack-resistant.
• Minimal foundations works required for installation.
• Long guideways for minimal wear and long-lasting machine precision.
• Excellent operator view of bending process.
• Rigid and compact machine frame requires minimal foundation work.
• Hydraulic rotation drives and breaks on all rolls.

Available Bending Capacities

• Sheet witdh: Max. 12000 mm
• Sheet thickness: Max. 200 mm for cold bending

Remarks: We can provide all plate rolling machine, as long as you provide these information as following:

Max. Plate Bending Thickness         such as "25mm"
Max. Plate Bending Width               such as "3000mm"
Mini. Rolling Diameter                    such as "φ500mm"
Plate Material                                  such as "carbon steel"
Yielding Limit                                   such as "245MPa"

Applications

• Petrol and Offshore (pressure vessels and heat exchanger; Silos and storage tanks; Steel structures for platforms and monopiles )
• Shipyards

2. The 4 roll hydraulic plate bending machine is a universally available four roller bending machine with linear hydraulic roll movement of side and bottom rolls. It can be used to roll tubes, tube segments, rounded boxes, ovals or other shapes.

The following basic operations can be used:

• Pre-bending of sheet edges
• Rounding of sheets into cylindrical shapes
• Cone bending
• Press bending for even and uneven radii
• Calibrating for minimization of radius variations in a welded tube

Advantages

• Work piece only needs to be aligned once at the start of the bending process.
• Automatic minimization of flat ends.
• Secured rolling traction throughout the process.
• Simple cone bending.
• Simple calibrating of apple- or pear-shaped welded tubes.
• Correction of axial offsets possible.
• Minimal wear on guide ways for long-lasting machine precision
• 42 CrMo rolls are very crack-resistant.
• Roll breaks allow blocking of rotation for pre-bending thus improving process-safety.
• Minimal foundations works required for installation.
• High-torque drives on bottom and top rolls.
