Hydraulic 4 Roll Tube Bending Rollers for Tubes and Pipes

Hydraulic 4 Roll Tube Bending Rollers For Tubes and Pipes

 

Our company adopt Italy advanced swing arm technology, combined with the characteristics of domestic products, developed 4 roll plate rolling machine, patent number ZL200820161151.5, its performance is superior to domestic equivalent products, with high efficiency, low energy, easy operate etc.


4 roll plate rolling machine, driven by the top and bottom rolls, single unit high torque hydraulic motor and planetary gear box are directly mounted onto each driving roll to ensure a smooth feed through of the plate, the bottom roll can be vertically moved to clamp the plate, the side rolls move up and down on planetary swing guides, all four rollers use spherical roller bearings, the advantage of this machine is that it can complete the pre-bending of both ends and rolling at one time. It can also perform certain shaping and leveling on the metal sheet, and smallest flat ends.




 

1. Extremely robust structure machined with PLC control machines

2. Oversized dimensions of hydraulic system and components to withstand heavy use and prolong durability with low maintenance

3. Two hydraulic motors coupled to planetary gear units for the rotation of the two central rolls

4. Hardened rolls / Hardened and polished rolls

5. Separate control desk on wheels

6. Hydraulic opening of shoulder by control desk

7. Hydraulic inclination of lateral rolls for conical bending directly from control desk

8. Numerical control for automatic production

9. Movements of rolls on swing guides to reduce flat part

10. It can be used to roll tubes, tube segments, rounded boxes, ovals or other shapes.

11. Sheet width: Max. 6000 mm, sheet thickness: Max. 150 mm for cold bending

12. Side rolls are free for rotation and upwards downwards movements are hydraulic powered

13. Top and bottom rolls are driven by hydraulic and gearbox. Bottom roll's vertical movements are hydraulic powered

14. Rolls rotation on high resistance selfaligning bearings

15. Rolls Cambering: know how variable cambering to avoid reel and barrel effect to increase bending performance and precision
