Main Components of the Production Line
Component | Function |
Decoiler (Uncoiler) | Holds and unwinds the steel coil (manual or hydraulic,3–15 ton capacity) |
Leveling Machine | Flattens the metal strip and removes residual stress |
Servo Feeder | Precisely feeds material into the punching station at controlled intervals |
Punching System | Punches holes,slots,notches,or embosses logos on the panel |
Roll Forming Machine | Gradually shapes the flat strip into the desired profile using multiple roller stations (12–35 stations) |
Cutting Unit | Cuts the formed panel to the required length (hydraulic or servo-driven) |
PLC Control System | Centralized control with HMI touch screen for parameter settings and monitoring |
Run-Out Table / Stacker | Receives and collects finished panels |
Step-by-Step Working Process
The typical workflow of a shelf board roll forming machine follows the sequence illustrated below:
Decoiling → Leveling → Servo Feeding → Punching → Roll Forming → Cutting → Discharging
Step 1: Decoiling (Uncoiling) The steel coil is loaded onto the decoiler using a feeding trolley or overhead crane. The machine unwinds the coil and feeds the leading edge into the leveler .
Step 2: Leveling (Straightening) The metal strip passes through a series of leveling rollers that flatten the material, removing curvature and twist. This ensures dimensional stability for downstream processes .
Step 3: Servo Feeding A servo-driven feeder grips the leveled strip and advances it precisely to the punching station. The servo motor allows for accurate length measurement and positioning .
Step 4: Punching (Pre-Punching or Inline Punching) The material enters a hydraulic or mechanical punching press. Holes, slots, or notches are punched according to the shelf design. This can be done:
Pre-punching: Pause-to-punch before roll forming
Tracking punching: Continuous punching without stopping
The punching mold is typically made of Cr12MoV or Cr12 steel, heat-treated to HRC 58–62 for durability .
Step 5: Roll Forming (Cold Forming)
The punched strip passes through a series of roller stations (typically 12–24 stations). Each station gradually bends the metal until the final profile is achieved. The rollers are precision-machined from GCr15 or Cr12 steel, hardened and chrome-plated for wear resistance .
Forming Speed: 6–22 meters per minute (depending on material thickness and hole pattern)
Width Adjustment: Many modern machines offer automatic width adjustment via electric motors, allowing different panel sizes without manual roller changes
Step 6: Cutting (Cut-to-Length)
Once the formed profile reaches the preset length, the cutting unit activates. Two cutting methods are common:
Hydraulic Cutting (Pause-to-Cut): The line pauses briefly while the blade cuts
Flying/Tracking Cutting: The cutting die moves with the material, allowing non-stop production
Cutting blades are made of hardened Cr12 or SKD11 steel .
Step 7: Discharging & Stacking
Finished shelf panels are discharged onto a run-out table. Some advanced lines include an automatic stacker that organizes panels for packaging
