oem highway guardrail roll forming machines are used to transform metal coils into long W-beam guardrails for installation along roads. As an original equipment manufacturer (OEM), these roll former lines can be customized to clients’ specifications for traffic safety barrier production.
Introduction to oem highway guardrail roll forming machine
Roll forming is a continuous bending process used to convert metal coils into customized longitudinal profiles via inline feeding and roller stations. OEM guardrail roll formers shape plain sheets into corrugated W-beam rails through:
Material Feeding
- Payoff reel to unroll coiled steel/aluminum
- Feed table with edge preparation tools
- Encoder controls feed speed synchronization
Profile Forming
- Series of roller blades shape metal incrementally
- Forming stations gradually bend metal into ribs
- Specialized tooling designs for W-beam
Design and Customization
- Machines can make standard or custom rails
- Operators program PLC for parameter changes
- Quick die changeovers for new profiles
OEM guardrail lines provide:
- High speed forming up to 40 m/minute
- Integrated punching and cutting
- Automated length control systems
- Customized roll pass design ability
- Consistent quality for road projects
Guardrail roll formers deliver higher outputs plus superior performance consistency compared to manual bending methods.
Major Components of Guardrail Lines
Component | Function |
---|---|
डेकोइलर | Feeds raw coil stock into machine |
Straightener | Removes coil curvature for flat feeding |
Roll forming stands | Each set of rollers shape W ribs |
PLC Control | Automates production monitoring |
Flying shear | Trims rails to length after forming |
Conveyors | Safely offloads finished guardrails |
Working Process of OEM Guardrail Roll Lines
The working principle utilizes specialized roller tooling to incrementally bend metal sheets into a W corrugated shape by passing strips through consecutive forming stations:
Step 1) The leveled strip from a decoiled metal sheet enters into the initial forming stands after the feed table.
Step 2) It passes between a series of top and bottom rollers designed specifically for W-beam contours.
Step 3) At each stand, the metal is bent further into wave-like ribs that make up the cross section.
Step 4) Reduced openings between rollers at each station provide needed clearances during shaping.
Step 5) Automatic gauges monitor strip alignment throughout the process.
Step 6) The formed W profile then goes for precision cutting as per length specifications.
Step 7) Formed guardrails exit the line on outfeed tables for bundling.
OEM machines enable pre-programmed recipes for efficient high speed production cycles to achieve construction project requirements.

सामान्य प्रश्न
Q: What thickness of coils can be formed into guardrails?
A: These machines typically process 1.2 to 4 mm strength steel coils for longitudinal barrier specifications. Up to 6 mm capacity is possible with customized roller design.
Q: What processes connect individual guardrail pieces?
A: Slotted joints with splice bolts are commonly used. Punching machines make slots in sides before anti-burst tubes get inserted and bolted on site.
Q: How is length of guardrails controlled during production?
A: Encoders feed strip at set speeds in sync with cutters. Length compensation via PLC ensures precision trimming matched to vehicle impact requirements.
Q: What factors affect choice of line speed for quality?
A: Roller material, frame rigidity, strip width, steel grade, thickness, straightness, and tensioning determine maximum line speed for defect-free ribbons.
Q: How can additional complexity be built into guardrails?
A: Secondary presses, punches, drilling machines, bending stations can be integrated in the line for custom holes, slots, contours if needed.
