Efficient Guardrail Bending Machine / Highway Guardrail Making Machine 90mm Shaft Diameter

Efficient Guardrail Bending Machine

• The Guardrail Bending Machine (also known as Road Barrier Bending Machine) is designed for bending highway guardrails with precision and efficiency. This machine is widely used in the road construction industry, especially for producing guardrails that provide safety and support along highways, bridges, and other infrastructure projects.
  
• Working Principle: The high-speed guardrail bending machine is typically driven by a hydraulic system or electric motor. It uses one or more bending rollers to push the guardrail material into the bending area. The material is gradually bent into the required shape under the pressure of the rollers. During the bending process, the machine's control system precisely calculates the parameters of each bending section to ensure the accuracy of the guardrail at every bending position.

• Advantages:

1. High Automation: Modern high-speed guardrail bending machines mostly use CNC (Computer Numerical Control) systems, allowing precise control of bending angles and radii, thereby improving production efficiency and product quality.
2. Wide Range of Materials: The machine can process steel plates of varying thicknesses and materials, such as hot-dip galvanized steel, cold-rolled steel, etc. Typically, the thickness of guardrail materials is 2.5-4mm, but the machine can be adjusted according to specific requirements.
3. High Precision Bending: The hydraulic or mechanical pressure ensures precise bending. The bent guardrails will have no cracks or deformation at the bends, and the bending radius will be consistent.
4. High Flexibility: The machine can adjust the bending angles and radii as needed, making it suitable for various construction requirements. It is particularly flexible for use on highway curves, exits, and other sections requiring custom-shape guardrails.
5. High Safety: The machine is equipped with advanced safety features, including emergency stop functions and overload protection, ensuring safe operation during heavy-duty production.
