The highway guardrail roll forming machine is a specialized roll forming device used for producing anti-collision guardrails for highways, mainly for manufacturing wave-shaped guardrail sheets. These guardrails serve a safety protection role on highways, effectively absorbing impacts and reducing accident injuries. The design of the highway guardrail roll forming machine is similar to conventional roll forming machines, but it is better suited for processing long-size, thick sheet materials, ensuring the strength and durability of the finished products.
Uncoiler
Used for bearing and feeding steel coil sheets.
Straightening device
Primarily straightens the steel sheets to ensure the material is flat and facilitates subsequent processing.
Forming host
The core processing equipment, which includes multiple sets of rollers that gradually press the steel coil sheets into wave-shaped or other required shapes of guardrail sheets.
Hydraulic punching system
Some guardrail sheets need to be punched during the forming process to facilitate subsequent installation. The punching system usually operates synchronously with the forming host.
Cutting device
Once the guardrail sheet is formed, the cutting system cuts it to the specified length, generally using a hydraulic cutting system to ensure a smooth cut.
Automatic stacking system
Automatically stacks the formed guardrail sheets, making subsequent loading and transportation convenient.
Control system
Uses PLC or touch screen controls to adjust forming speed, punching position, cutting length, and other parameters to meet different production needs.
After the equipment starts, the coil sheets are fed into the straightening device by the uncoiler for flattening. Then, the material enters the forming host, where a set of gradually changing rollers press it and gradually form it into the wave-shaped guardrail. After forming, the sheet is processed by the punching and cutting systems according to the set hole positions and lengths and finally automatically stacked in the designated position.
High production efficiency
Highway guardrail roll forming machine manufacturers focus on production efficiency improvement. The highway guardrail roll forming machine can quickly process coil sheets into finished products, suitable for large-scale continuous production.
High degree of automation
The highway guardrail roll forming machine can achieve automatic feeding, forming, punching, cutting, and stacking, reducing manual involvement and improving production efficiency.
Strong adaptability
By changing molds and adjusting roller sets, different specifications and shapes of guardrail sheets can be produced to meet different guardrail needs.
Stable product quality
High equipment precision ensures the consistency in size and standard shape of the finished guardrail sheets, meeting highway safety standards.
Low material loss
Minimal material loss during the roll forming process, with good forming effects, resulting in smooth and burr-free surfaces on finished products.
This highway guardrail roll forming machine is mainly used to produce anti-collision guardrail sheets for highways and municipal roads and can be used to produce the following types of guardrails:
Double-wave guardrails
The most common wave-shaped guardrail type, with two-wave anti-collision structures, suitable for general road sections.
Triple-wave guardrails
Possess stronger anti-collision capabilities, suitable for hazardous sections like bridges and steep slopes.
Galvanized guardrail sheets
Guardrail sheets can undergo hot-dip galvanizing after production to enhance corrosion resistance, making them suitable for high-humidity or coastal environments.
To ensure the long-term stable operation of the highway guardrail roll forming machine, the following daily maintenance is recommended:
Regular inspections
Check key components of highway guardrail roll forming machine such as rollers, hydraulic systems, and cutters to ensure there is no wear or malfunction.
Lubrication maintenance
Regularly apply lubricant to parts of highway guardrail roll forming machine such as rollers and guides to reduce friction.
Cleaning maintenance
Keep the highway guardrail roll forming machine clean, especially the rollers and cutters, to prevent affecting forming precision.
Regular calibration
After prolonged use of the equipment, it is recommended to calibrate parameters such as forming positions and cutting lengths.
The highway guardrail roll forming machine is an important traffic safety equipment. It features efficiency, automation, and strong adaptability, making it a key device in the highway guardrail manufacturing industry.
