1. Product Definition and Working Principle

Definition: This equipment is an automated industrial machine based on the continuous cold roll forming process. It utilizes a series of high-precision forming rollers arranged along specific trajectories to progressively plastically deform metal strips, ultimately rolling them into profiled steel sheets for construction with specific cross-sectional shapes.

Working Principle: Metal coils are uncoiled and fed into the roll forming main unit, which consists of multiple forming stands. Under the progressive bending action of each set of rollers, the cross-sectional shape of the strip gradually changes until it is fully formed into the desired floor deck profile at the final stand. The formed product is then cut to a fixed length and output as the finished product.

Function Description

Key Components and Technical Features

1. Loading and Uncoiling System

Supports the raw material coil and enables smooth uncoiling and feeding.

Uncoiler: Equipped with a hydraulic expanding mandrel and a pressing arm to prevent loosening.
Guiding Device: Ensures strip alignment and smooth entry into the next process.

2. Roll Forming Main Unit

The core system responsible for shaping the cross-section of the material.

Forming Stand: Constructed from high-strength welded steel plate housing, stress-relieved for excellent rigidity.
Forming Roller Shaft: Forged from high-quality alloy steel (e.g., GCr15), precision-machined via CNC, heat-treated, and hard chrome-plated for high wear resistance.
Gear Transmission System: Uses enclosed herringbone gearboxes or universal joint drives to ensure high synchronization accuracy, smooth operation, and low noise.
Bearings: High-load capacity double-row roller bearings.

3. Hydraulic/Servo Cutting System
