4-Roll Hydraulic Plate Bending Machine

 

RBD-4H

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

  • Very suitable for light and medium plates, aluminum or stainless steel bending
  • Ferrules in full circle or varying radiuses can be done easily
  • Pinch roll and lateral rolls move with pyramid linear direct movement by hydraulic pistons
  • Overload protection
  • Top roll is powered by electrical motor and planetary gearbox. Bottom roll powered with cardan joint system (two rolls powered)
  • Three digital readouts for easy roll positioning
  • Hydraulic drop-end for easy removal of finished ferrule
  • Easy operation with mobile control panel
  • Welded, heavy steel frame
  • Induction hardened rolls made of SAE 1050 (CK 45) steel
  • Conical bending device
  • Hydraulic balancing system

Optional configuration
