1. Overview of Scaffold Walk Board Roll Forming Machine
The Foot Pedal Cold Bending Forming Production Line adopts coiled metal strips as raw materials.
Through decoiling, continuous roll forming, and automatic cutting, the system produces customized profiles with high dimensional accuracy.
The roll forming section is designed with German COPRA software and simulated using FEA finite element analysis to ensure the highest precision.
The whole line applies PLC control with variable frequency speed adjustment, enabling continuous, automatic, and stable production — ideal for steel structure and metal cold forming industries.
2. Profile Cross Section
The final profile shape will be determined based on drawings confirmed by both parties.
3. Production Process
Decoiling & Leveling 2 in 1 → Servo Feeding + Punching (Stretching & Hole Forming) → Guiding → Clamping → Forming (Closed Triangular Wave Shape) → Riveting → Edge Forming → Riveting → Servo Tracking Saw Cutting
