4-Roll Hydraulic Bending Machine

RBD-4HD • RBD-4HL

These state-of-the-art hydraulic 4 roll benders use top brand components like Siemens, Rexroth, Bosch, Parker, Atos, Telemechanique, SKF, NSK and FAG to ensure highquality lifelong performance. Over 50 years of experience in sheetmetal bending and thousands of reference customers will guarantee you first class support in any application or maintenance question. With our optional extras you can upgrade the level of automation, which will raise your production and flexibility. Our machines are widely used in shipbuilding, tank and truck industries. Also in the wind-power sector, food and construction sectors.

  • For medium and heavy bending tasks
  • The frame is of solid welded construction
  • All rollers have high-quality, heavy-duty ball bearings, which ensures minimum friction and even rotation of the bending rollers
  • Hydraulic roller is driven by independent drive motors and planetary gearboxes
  • Because the planet gears are mounted directly on the rollers, the transmission of force takes place without loss of force or power
  • The simultaneous use of torsion bars and hydraulic units ensure maximum machining accuracy and production flexibility

Standard configuration

  • Overload protection
  • Hydraulic top and side rolls (3 pcs.)
  • Digital readout for top and side rolls
  • Hydraulic closure for easy removal of bent parts
  • Welded, heavy steel frame
  • Induction hardened rolls made of SAE 1050 (CK 45) steel
  • Conical bending device
  • Automatic lubrication
  • Electronic/mechanical balancing device
  • 2 bending speeds
  • Operation manual

Optional configuration

  • NC or CNC control system for bend automation
  • Central overhead support
  • Lateral supports
  • Material feeding
  • Continuous bending speed
  • Hydraulic work piece ejector
  • Ground and polished rolls
  • Small top roller for minimum bending radii
