C Steel Roll Forming Machine

1.General Overview

C Steel Roll Forming Machine is an automatic continuous cold-forming production line specially designed to manufacture C-shaped steel purlins from flat metal coils via cold bending processing without heating treatment.Through multi-pass precision roller sets,flat steel strips are progressively bent into standard C-section profiles including web,flanges and curled edge,completing uncoiling,leveling,pre-punching,roll forming,fixed-length cutting and finished product output in one streamlined flow.Widely recognized as core processing equipment for steel structure construction industry,it supports flexible size adjustment to produce multiple specifications of C purlins on single unit.

2.Complete Production Process Flow

Decoiler→Material Feeding&Guiding→Straightening&Leveling→Hydraulic Pre-punching→Main Roll Forming→Hydraulic Flying Cut→Finished Product Collecting Table

Uncoiler:Hydraulic/mechanical decoiler(3–5 tons load capacity)holds raw steel coil and feeds strip steadily with constant tension control.

Leveling Unit:Removes raw material camber and deformation to guarantee flat feeding for precise forming.

Punching Station:Hydraulic punching system pre-drills connecting bolt holes on purlin web/flange as customer drawing requirement,avoiding secondary off-line machining.

Roll Forming Host:Core forming section with 16–22 groups precision roller stations,gradually shaping steel into qualified C profile.

Cutting Device:Hydraulic flying shear with Cr12MoV quenched cutter blade,realizing non-stop online cutting for fixed length,smooth burr-free cutting surface.

Output Rack:Automatically receives finished C steel for stacking and collection.

3.Core Technical Advantages&Features

3.1 High Precision&Stable Dimension

Equipped with Siemens/Delta PLC touch screen control system,all production parameters(length,punching position,forming size)digitally set on panel;finished purlin dimensional tolerance controlled within±0.2mm per meter,uniform cross-section without distortion.Quick-adjustable frame design enables fast switch among different C steel sizes(web:80–300mm,flange:40–80mm)within short time without replacing rollers.

3.2 Heavy-duty Durable Structure

Machine frame:Integrated heavy H-beam welded frame,high rigidity to resist forming vibration during long-hour continuous operation.

Forming rollers:Made of GCr15/Cr12MoV alloy steel,overall quenching&chrome plating treatment,wear-resistant with service life over 100,000 working hours.

Transmission:Standard chain+gear synchronized drive system,stable running,low failure rate.

3.3 Wide Raw Material Compatibility

Available to process Galvanized steel(GI),PPGI prepainted steel,cold rolled carbon steel,partial aluminum alloy strip,applicable material thickness ranging 0.8mm–3.0mm as customized design.

3.4 High Production Efficiency

Normal operating speed:8–22m/min;high-speed non-stop flying-cut model reaches 30–40m/min,greatly lifting daily output and cutting manual labor cost by over 60%vs traditional separate processing mode.Full automatic running reduces human intervention from coil to finished products.
