Our W12NC series CNC hydraulic plate bending machine is a now state of the art 4 roll plate roll in the world, combined with the extreme versatility, proven reliability, and performance. It can pre-bend the end of plate in both sides without having to turn it the other way around. For fabricators, welding shops, maintenance shops and production applications in oil, chemical, boiler, shipbuilding hydro power, metal structure and machine manufacturing industries, this 4 roll plate bender is preferred choice for rolling cylindrical, arc and conical workpieces.
1. The hydraulic plate bending machine comes with four rolls. Top roll is driven by gear reducer or hydraulic motor to offer torque for bending. Pinch roll is driven by hydraulic cylinder to move vertically. Two side rolls driven by hydraulic cylinders move up and down slantwise.
2. Four rolls are all made of 42CrMo steel. Forging and surface hardening processes provide the HB250～280 surface hardness, excellent wear resistance and long lifespan.
3. Bearings at two ends of the working roll are self-aligning roller bearings, ensuring small friction coefficient, reducing power consumption and saving energy.
4. The CNC plate roll is designed with a high precision displacement sensor for monitoring the positions of pinch roll and side rolls.
5. An encoder is mounted on the top roll to clearly pinpoint the rotation position of the roll and thereby to easily find the seam of cylinder.
6. Mobile CNC control panel is provided for easy operation. Through the touch screen on the panel, operator can clearly see the positions of three working rolls.
7. The control system with OMRON intelligent PLC controller boasts strong resistance to interference, high longevity, remarkable running stability and other notable advantages.
8. Main hydraulic manifolds are from Taiwan NORTHMAN, which come with large flow, tiny resistance, low pressure loss and low heat.
9. Hydraulic driven drop end delivers high reliability and convenience for finished components unloading.
10. The 4 roll plate bending machine is fitted with a balancing device at the end of top roll to balance the top roll when the drop end turns over.
11. The hydraulic system comes with oil filter for system cleaning as well as air filter for normal air in and out of oil tank and water evaporation. It is equipped with a double-way safety protection device to maximize safety in use.
12. Hydraulic drop end of the 4 roll plate bending machine, namely unloading device is driven by a hydraulic cylinder to realize automatic drop and erection, thus ensuring ease of workpiece unloading. Due to an interlocking device, other actions of the machine will stand by when the hydraulic drop end turns over, and only after the drop end erects can the machine runs again. This ensures high safety.
The sheet metal bending machine is excellent for use in tank truck, chimney, chemical, hydro power, thermal power, shipbuilding, aviation, pressure vessel, pipe, tunnel, bridge, metal structure and machine manufacturing industries.
