STANDARD ACCESSORIES

  • Very suitable for medium and light plates or stainless steel bending
  • Ferrules in full circle or varying radiuses can be done easily
  • 1Pinch roll and lateral rolls move with hydraulic pistons in orbital way. Between Ø 90-Ø 140 mm models are with lineer movement, between Ø 150-Ø 260 mm models all are with orbital movement
  • Overload protection
  • 2Top Roll is driven by a hydromotor and planetary gearbox and bottom roll is driven by a gear and cardan system
  • 3Three digital readouts for easy roll positioning
  • 4Hydraulic Drop-End for easy removal of finished ferrule
  • 5Easy operation with mobile control panel
  • 6Welded steel frames
  • 7Induction hardened forged or rolled SAE 1050 (CK 45-50) Steel rolls
  • 8Conical Bending device
  • Hydraulic balancing system
  • 9Double speed working system

OPTIONAL EQUIPMENTS

  • 1Automation with NC and CNC control
  • 2Overhead crane for large diameters
  • 3Hydraulic lateral side supports for large diameters
  • 4Hydraulic plate ejector
  • 5Polished rolls for special jobs
  • 6Infinitively variable speed system
  • Electronical balancing system for parallel movement of the rolls
Without Pre-Bending, flat plate ends may remain depending on diameter.

Plate bending capacities are given for 260 N/mm2 plate yielding strength.
All technical specifcations are subject to change without notice.

As an addition to the sectors that HSS models used, 4R HS Models can be used at the production such as Rim of Wheel, exhaust production, oil tank that has smaller diameters. Differently from HSS Models, on this models there is a single engine, single gearbox and torque motor. The pump starts the lubrication operation with the power that comes from electromotor and by the help of valves and hydraulic hoses it transmits to the gearbox directly.

Top roll ,mounted to the gearbox, is facilitated movement togetger by the torque-engine rotates the gears. As a difference, On this model side rolls and bottom rolls are free-idle and returns with material together. Side rolls up and down movements provided by the cylinders and the movement of linear give place to the orbital called movement. Bottom roll is moved up and down by the method of ramp system called. On all rolls used ball-bearing thus orbital movement is provided. 3 pcs.

Digital read-outs located on control panel as standard makes possible to read the position of side and bottom rolls digitally besides it helps limiting adjustment.
