This trapezoidal roof panel roll forming machine is a high-efficiency, fully automatic cold roll forming line developed by Hebei Xinnuo Machinery, specially designed for producing high-quality trapezoidal metal roofing panels. It realizes one-stop automatic production from coil uncoiling, leveling, roll forming, fixed-length cutting to finished product output, with stable performance, high forming accuracy and long service life. It is the ideal equipment for steel structure construction, industrial plants, warehouses and commercial buildings.

 

Core Advantages

• Adopts 45# forged steel rollers with hard chrome plating, quenched to HRC58-62, ensuring no scratches on the sheet surface and consistent panel shape
• 75mm large-diameter solid main shaft with strong rigidity, no deformation during high-speed operation, forming accuracy up to ±0.8mm
• Step-by-step progressive forming technology eliminates sheet stress rebound, ensuring flat panels and tight waterproof splicing
   
   
  ✅ Intelligent Automatic Control
   
  • Equipped with Siemens/Delta PLC + 10-inch touch screen, supporting multi-language operation, one-key setting of length, speed and batch count
  • Omron high-precision encoder for closed-loop control, cutting length error ≤±0.5mm, no burrs
  • Automatic flying shear cutting realizes non-stop production, improving efficiency by 30% compared with traditional models
  • Complete safety protection system (emergency stop, overload protection, safety guard, door interlock) meets CE standards
   
  ✅ Heavy-Duty Durable Structure
   
  • 350H steel welded main frame with overall stress relief annealing, 16mm thick middle plate, low vibration and low noise (≤72dB) during long-term operation
  • Gear + chain dual transmission system with high transmission efficiency ≥93%, maintenance-free for 2 years
  • Automatic centralized lubrication system reduces component wear by 70% and extends service life
