4 Roll Plate Rolling Machine
- 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
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
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
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
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
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.
