Product detail:

Character of SL hydraulic four roller mild steel plate rolling machine/ hydraulic 4 roller plate rolling machine, W12-60*3200, W12-120*3000 IN STOCK

  

The 4 roller hydraulic mild steel 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 of four roller plate bending machine

• 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.

Available Bending Capacities of 4 roller plate rolling machine

• Sheet width: 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"

 

Applications of 4 roll plate bending machine

• Marine and storage tank construction
• Boiler and heat exchanger production
• Bending work on reactor assemblies
• Steel structures (Section bending, pipe construction, cones, domes)
• Pipelines onshore & offshore
• Wind tower (we can also provide wind tower production line)
• Shipping industry (from bending ship hulls to production of submarine hulls

 

 

The 3 roller hydraulic plate bending 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 roller 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 & cylinders
  • Calibrating for minimization of radius variations in a welded tube  

  Advantages of 3 roller plate bending machine

  • Excellent bending results due to total machine symmetry structure.
  • 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 of 3 roller plate rolling machine

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

  Applications of three roller plate bending machine

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