High-Speed Roll Former for W-Shape Highway Guardrail Production with Hydraulic Punching
These introductions refer only to the production line and configuration shown in the main image. Each machine is custom-built. Metalign welcomes your inquiry and provides the right production line—forming metal into profiles aligned to your needs.
1. Production Line Overview
This production line is tailored for producing high-strength W-shaped guardrails used in highway safety applications. It efficiently processes 3-4mm cold-rolled steel, incorporating advanced punching and forming technologies, and ensures a smooth end-to-end manufacturing process with magnetic stacking for easy handling.
2. Profile Description
The W-shaped guardrail is manufactured using cold-rolled steel with a thickness of 3-4mm. Its unique design ensures it offers enhanced protection for road users. The production line is highly efficient and can produce durable guardrails quickly, making it ideal for large-scale road safety projects.
3. Production Process
5T Hydraulic Decoiler → Guide → Leveler → Hydraulic Punching → Hydraulic Pre-cutting → Transmission Platform → Roll Former → Auto Stacking System
The steel coil is fed into the decoiler and guided into the straightener. After being punched and pre-cut, it moves to the roll former, which shapes the guardrail. The magnetic stacking system handles the finished panels, ensuring safe, efficient stacking.
4. Technical Parameters
| Machine | Analysis |
| 5T Hydraulic Decoiler | Feeds and unwinds heavy steel coils with controlled tension. |
| Shovel-type Guide | Ensures accurate feeding of thick steel into the forming machine. |
| Independent Straightener | Smooths the steel coil independently, ensuring proper thickness for forming. |
| Hydraulic Punch | Performs precise, high-power punching for faster, efficient production. |
| Four-column Hydraulic Punch | Ideal for heavy-duty punching, offering increased efficiency and reduced wear. |
| Hydraulic Pre-cut | Cuts the steel before shaping, ensuring consistent panel dimensions. |
| Transmission Platform | Coordinates the speed between cutting and forming, improving efficiency. |
| Roll Former | Shapes the steel with 18 forming stations, powered by a gearbox for smooth operation. |
| Magnetic Stacking | Safely handles and stacks heavy guardrails, boosting productivity and safety. |
5. Key Focus
Precision Punching: High-efficiency hydraulic punching with a four-column setup, designed for thicker steel.
Magnetic Stacking: The system uses magnets to stack heavy guardrails safely, increasing productivity.
Heavy-Duty Handling: Ideal for 3-4mm cold-rolled steel, ensuring durability and long-lasting performance.
