PRS 3/8″ Plate Roller

1/4″ 4-Roll Plate Bending Machine

PR4 4 Roll Plate Rolling Machine offers many advantages. PR4 is the easiest CNC hydraulic plate bending machine to use, thanks to the ability to pinch the plate between the two motorized central rolls, to make the pre-bending at the end, and the bending thru the whole body in a single direction and in one pass process. The plate is kept squared without slipping during the pre-bending and bending cycle, thanks to the constant pinching of the central rolls. This makes the PR4 4 Roll Plate Bender perfectly suited to be controlled by NC or CNC numerical control.

Main Features

  • 3 digital readouts give accurate roll locations for easy repeatability.
  • The operator control pedestal lets you conveniently manage all movements of the machine.
  • An industrial hydraulic motor moves the lateral rolls.
  • The streamlined design originated from the EU, adopting whole welding and annealing treatment of the machine frame to eliminate stress, keeps the machine rigid and helps prevent flex.
  • Adopting Germany Bosch Rexroth integrated hydraulic system, the hydraulic drive is stable and reliable, and can effectively reduce the problems caused by oil leakage.
  • The planetary gearbox, connected to the main motor, drives the top and bottom rolls at a solid 16 feet per minute.
  • Fixed top roller, and lower roller driven by hydraulic oil cylinder, left and right side rollers are driven by hydraulic pistons for diagonal movement. Direct linear piston movement for the lateral and forming rolls delivers even more power.
  • CNC control, three groups digital readout shows the position of working roller, high accuracy, and good roundness, material aligning is convenient and accurate, avoid the wrong side phenomenon.
  • Hydraulic Drop-end for easy removal of finished ferrule.
  • SAE 1050 Quality Certificated induction hardened forged steel rollers with high strength.
  • Hydraulic balancing system with self-tapping conical bending device is convenient for bending cone.
  • Permanent lubrication technology (bearings needn’t be oiled within service life), easy to add handling device, feeding device and material supporting device.
  • Consistently tightly clamp the top and bottom rollers during rolling process to prevent plate sliding.
  • Blade clearance quick adjusting mechanism, simple and quick manual adjustment method, supporting stepless adjustment of blade clearance
