features

1. The upper roll is fixed and the central lower roll moves by means of a hydraulic cylinder to grip the sheet metal
2. Central rollers driven by hydraulic motor coupled to the planetary gearbox directly
3. Two side rolls move with hydraulic pistons
4. The two side rolls traverse along swing guides to ensure the shortest flat end and effective pre-bending
5. All the rolls are mounted on spherical roller bearings (Long life lubricated)
6. Bending rolls synchronization and balancing control fully electro-hydraulically controlled
7. Central lower roll and side rolls tilting from operator control panel
8. Hydraulic drop-end for ease of finished cylinder removal
9. Easy operation with working table
10. Digital read-outs

 

Advantages
1 Simple calibrating of apple- or pear-shaped welded tubes
2 Can be controlled by CNC numerical control
3 Minimal wear on guide ways for long-lasting machine precision
4 High strength steel rolls are very crack-resistant

 

Application
Wind towers, off-shore platforms, aerospace / aircraft, shipyard, energy industry, boilers, pressure vessels, heat exchangers, earth moving machines, truck containers, steel structure etc
