Product Description
- CNC Four rollers hydraulic plate rolling machine
- With Prebending
- Prebending & rolling can be automatically achieved one time on one working cycle.
- Top roller is powered roller
- Lifting of bottom roller and two side rollers driven hydraulically
- Displacement of bottom roller and two side rollers lifting controlled by CNC
- Display on screen for displacement
-  Synchronous precision ±0.1mm
-  Balance at the tail of top roller for conveniently unloading finished workpiece
- Independent operating station
- with safety interlocking

Mechanical part
  • 42CrMo material of rollers with HB220-260°/HRC45-50°hardening
  • Whole welded machine frame to eliminate internal stress
  • Powered top roller with turnover oil cylinder and balance mechanism at the ends to unload workpiece easily
  • Bottom roller and two side rollers driven by oil cylinder at the ends. Bottom roller makes up & down lifting movement, and two side rollers do inclined lifting movement. Liftable synchronization controlled by computer. Rollers can stop at any required position.
  • Using ball bearing at the end of rollers with smaller friction coefficient and reducing energy consumption
Hydraulic system
  • Function: Drive cylinder to make lifting movement; Drive two side rollers to do inclined liftable movement; Drive the turnover oil cylinder to do lifting movement
  • Turnover oil cylinder installed one-way throttle valve to adjust the speed
  • Hydraulic pipe joint with radial seal to avoid leaking
  • With oil filter on pipeline and air filter in oil tank to ensure cleanliness

Electrical system
  • Omron PLC programme with diagnosis, monitoring, logic processing, memory and interlocking
  • Movable operating station with touch screen displaying
  • High accuracy optical encoder to ensure positioning accuracy and monitor the position of all rollers.
  • The function of control system
  1. Automatically control working rollers do synchronization movement Control the bottom roller lifting synchronization, accuracy ±0.2mm.
    Control two side rollers lifting synchronization, accuracy ±0.2mm
  2. Show real time data of rolling plate, including:Two ends absolutely position showing at real time of bottom roller.
    Two ends absolutely position showing at real time of two side rollers.
    The ends gradient showing at real time of bottom roller
    The ends gradient showing at real time of two sides rollers
  3. Automatic failure alarm
