Standard PRH4-25x3000mm Hydraulic 4-Roll Plate roller with Double Initial Pinch (Pre-Bend): 

The four-roller metal plate bending machine is automatic, with international advanced technology, the rounding program is automatically formulated, it has a full hydraulic drive with intelligent control and automatic rounding of the CNC metal plate bending machine. This piece of equipment has the capability for batch rolling round multi-segment arc, square, cone and special-shaped work pieces.

A hydraulic 4-roll plate roller with pre-bend is a machine tool used for bending and forming sheet metal. It uses four cylindrical rollers, which are powered by hydraulic motors, to bend and form the metal. The top roll is typically the operator's side and is used to adjust the bend angle while the bottom roll is typically the drive roll and is used to apply pressure to the metal. The machine typically features pre-bending capabilities, which allows the operator to make a small bend in the metal before the main bending operation. This helps to reduce the amount of force required to achieve the desired bend angle, and also helps to prevent cracking or other defects in the metal.

Main Features:

  • One-time roll forming, intelligent control.
  • Visual input touch screen, editing process steps, which can store 100 sets of data EPS electronic balance system, the system keeps the roller movement parallel within 0.10mm range.
  • Self diagnosis fault, man support machine dialogue, intelligent judgment of operating errors.
  • This machine is driven by hydraulic cylinders with high repeatability.
  • The 4 - roller shaft is driven by multi-stage deceleration hydraulic pressure, the large torque is stable and reliable.
  • Steel plate welded integral frame and base to meet medium and large rolling strength.
  • The frame and the base are annealed as a whole to eliminate stress and never deform.
  • The roller shaft is forged as a whole and has undergone hardening treatment process of quenching and tempering.
  • Compatible with manual and automatic modes.
  • Max Bending Thickness - 25mm = 0.984 inches
  • Pre-Bending Thickness - 20mm = 0.787 inches

How to use a Hydraulic 4-Roll Plate roller with Pre-Bend

To use a hydraulic 4-roll plate roller with pre-bend, follow these general steps:

  1. Start by preparing the sheet metal that you want to bend. Make sure that it is clean, free of any debris, and properly aligned.

  2. Adjust the top roll to the desired pre-bend angle. This roll will be used to make a small bend in the metal before the main bending operation.

  3. Position the sheet metal between the bottom roll and the top roll, with the pre-bend angle facing up.

  4. Slowly begin to apply pressure to the bottom roll, using the hydraulic motor. As the metal begins to bend, continue to adjust the top roll to achieve the desired angle.

  5. Once the desired bend angle is achieved, stop the machine and remove the sheet metal.

  6. Repeat the process for any additional pieces of metal that need to be bent.

It's important to note that before using the machine, the operator should be trained and familiar with the machine operation and safety measures. Also, the machine should be properly maintained and in good working condition.
