I. Core Materials & Structure
1. Machine Frame
Material: High-strength steel plate (Q345B) integrated welding
Property: Torsional stiffness >18 kN·m/rad, ensuring zero deformation under heavy loads
2. Roller System
Base Material: D2 tool steel (equivalent to Hitachi SKD11)
Treatment Process:
Vacuum quenching to HRC 58-62 hardness
Chrome plating (Middle East version) or nitriding (tropical version)
Structure: 12-16 adjustable roll stands for synchronous bicurvature forming
3. Transmission Mechanism
Gearbox: Hardened helical gears (ISO 1328-1 precision)
4. Control System
Industrial PLC (Siemens S7-1200 or Mitsubishi FX series)
Laser encoder positioning accuracy: ±0.1mm
II. Compatible Materials
| Material |Thickness | Forming Limits | Typical Applications |
|--------------------|---------------|-----------------------------|--------------------------------|
| Aluzinc Steel | 0.4-1.0mm | Min. radius ≥450mm | Middle Eastern residential/commercial buildings |
| Copper Plate | 0.8-1.2mm | Requires polished rolls | EU church restoration |
| PVC Sheet | 1.5-3.0mm | Requires heated rolls >60°C| Post-disaster temporary housing|
| Titanium Zinc | 0.7-1.0mm | Roll pressure ≤8MPa | Cultural landmark buildings |
> Note: Aluminum compatibility varies by alloy (5052/H24 recommended), requires customized roll gap compensation.
III. Precision-Adapted Scenarios
1. Religious Building Domes
Requirements:
Curvature tolerance: ±0.5% radius (e.g. ±3mm for 600mm radius)
Aesthetics: Color consistency (ensured by continuous forming)
Machine Features:
Bicurvature synchronous control
Mirror-polished rolls (copper version)
2. Typhoon/Rainstorm Regions
Requirements:
Wind load resistance: >2.5 kPa
Waterproofing: ≥15mm interlock depth
Machine Features:
Integrated locking edge rolls (SE Asia version)
Reinforced cutting blades (minimizes sealing failure)
