High-Precision Forming

• Rollers are made of Cr12MoV mold steel, heat-treated to hardness HRC 58‑62, ensuring wear resistance and deformation resistance.

  
  

• Electric servo adjustment of roll gap, angle, and height with precision of ±0.05 mm.

  
  

• Automatic compensation for material springback to guarantee dimensional accuracy and perpendicularity of the frame.

  
  

Dedicated Section Adaptability

• Capable of forming various structures such as L‑shaped, U‑shaped, and special‑shaped enclosed frames.

  
  

• Supports integration of functional features like flange edges, sealing grooves, and connection holes.

  
  

• Suitable for a variety of materials including galvanized sheet, cold‑rolled sheet, and stainless steel.

  
  

Intelligent Control

• PLC with HMI (Human‑Machine Interface) stores multiple sets of valve specification parameters.

  
  

• Automatic fixed‑length cutting with length accuracy of ±0.5 mm.

  
  

• Real‑time monitoring of forming quality, with anomaly alarm and data logging.

  
  

Efficient and Flexible Production

• Adjustable forming speed: 6–18 m/min.

  
  

• Quick‑change design to accommodate production of multiple valve‑frame specifications.

  
  

• Optional modules: online punching, riveting, and automatic stacking.
