Core Structure and Functional Features

High-Rigidity Forming Frame

• Integral welded heavy steel structure, stress-relieved for high stability

  
  

• Gantry-type layout with strong anti-eccentric load capacity, suitable for high-strength material forming

  
  

Precision Forming System

• Forming rollers made of alloy tool steel (e.g., Cr12MoV), heat-treated to hardness HRC 58-62

  
  

• Each forming pass equipped with independent fine-adjustment mechanism, adjustment accuracy ±0.1mm

  
  

• Progressive forming design effectively controls material springback

  
  

Intelligent Control System

• PLC + industrial touch screen control, supports recipe storage and recall

  
  

• Automatic fixed-length cutting, accuracy ±1.0mm

  
  

• Features fault self-diagnosis and production data traceability

  
  

• Remote monitoring interface optional

  
  

Flexible Production Configuration

• Quick roller change design, adaptable to square, rectangular, C-section, and other profiles

  
  

• Optional modules: automatic punching, online welding, automatic stacking

  
  

• Material width adaptive, typically 200-600mm

  
  

III. Main Technical Parameters (Standard Type Reference)

Types of Guardrail Crossbeams That Can Be Produced

• Corrugated beam guardrail crossbeams (two-wave, three-wave specifications)

  
  

• Municipal guardrail crossbars (square tube, rectangular tube)

  
  

• Bridge collision barrier crossbeams

  
  

• Railway protective fence crossbars

  
  

• Scenic area, industrial park isolation guardrail components

  
  

Process Flow

Material loading and uncoiling → Leveling and centering → Pre-forming → Main forming → Fixed-length cutting → Finished product output

(Optional processes: online punching, end forming, automatic welding, surface pretreatment, etc.)
