W12 CNC 4-Roller Plate Bending Machine

The top roller is driven by hydraulic motor. Through the friction between the metal plate and the top roller to drive the bottom roller and side roller rotate. which supply the torque for bending plate. The bottom roller, side roller and drop end are all driven by hydraulic pressure.
Bending Thickness: 4-60mm
Pre-bending Thickness: 3.5-48mm
Roller’s Working Length: 2050-3100mm

Quantity:
  • W12 CNC Series
  • Durmapress

Product Description

General Features

  • Totally European design , streamlined looking , frames of our machines are fabricated , welded steel ( ST-52). Roll shafts , materials and bearing used in production are European quality . Also the torque limit of the machines is very high . CNC Playback and CNC graphic control systems are available as optional accessory .

  • The main structure of the equipment includes upper roller , lower roller and horizontal movement mechanism , supporting mechanism , main drive mechanism ,downturn system , left and right machine frame , chassis and balance mechanism , hydraulic and electrical control systems 

  • The model MH has both the upper and the lower roll powered with hydraulic motor and planetary gear box .

  • High precision pre-bending , freely setup the width of plate. Upper roller presses the plate end for pre-bending .

  • Upper roller likes drum with collaboration of carrier roller permit continual bending of any thickness of plate .

  • Safe work , fixed two down roller , upper roller does horizontal and vertical movement , and the plate don’t move during upper roller moving 

  • Unitary structure, convenient to move the whole machine as machine has a hardy under pan. No need to anchor bolt . 

  • Different use has different control way , like top numerical control and below numberical control 

  • Through exclusive technology , Durmapress can develop cones as easily as competitive machines can develop cylinders . And it eliminates scarring on the surface of shell or roll and also eliminates , in most caes , the need for grinding the lamination ( Bullnosing ) on the minor diameter edge .
