I. Equipment Overview
The Roll Forming Machine for Shutter Doors is a specialized metal processing device designed to continuously shape metal coils (e.g., galvanized steel, aluminum alloy) into shutter door slats (blades) through multi-stage roll forming. Its core function is to transform flat metal strips into shutter door components with specific cross-sectional profiles using progressive bending via rollers. The machine is characterized by high efficiency, precision, and automation.
II. Structure and Components
1. Uncoiler
Holds and feeds metal coils smoothly, typically equipped with hydraulic or electric tension control for consistent material delivery.
2. Guiding and Straightening Unit
Straightens the coil to eliminate curvature or waviness before entering the roll forming section, ensuring precision.
3. Roll Forming Main Unit
Multiple Roller Dies: Configured with sequential roller sets to gradually bend the metal strip into the desired profile.
Drive System Powered by a motor and gearbox to synchronize roller rotation for stable, continuous forming.
4.Cutting Device
Automatically cuts formed shutter slats to preset lengths (via hydraulic shearing or pneumatic punching).
5. Collector/Stacking Unit
Collects finished products, with optional automatic stacking or rewinding capabilities.
6. Control System
Uses PLC or CNC systems for speed adjustment, length setting, fault alarms, and human-machine interface (HMI) operation.
III. Working Principle
1. Uncoiling and Straightening
The metal coil is uncoiled and straightened to remove residual stress, ensuring flat entry into the roll forming section.
2.Progressive Roll Forming
The strip passes through multiple roller dies, with each stage incrementally bending the material to create wave-like, hooked, or hollow profiles.
3. Fixed-Length Cutting
Encoders or photoelectric sensors detect the length of the formed slats, triggering the cutter at preset intervals.
4. Product Collection
Cut slats are automatically stacked or wound for subsequent assembly or packaging.
IV. Key Features
1. High Efficiency
Continuous roll forming achieves speeds of 10-30 m/min, ideal for mass production.
2. Precision Forming
CNC-machined dies and adjustable roller gaps ensure consistent profiles and tight tolerances (±0.1 mm).
3. Material Versatility
Processes galvanized steel, color-coated steel, stainless steel, or aluminum alloys with thicknesses of 0.3-1.2 mm.
4. Flexible Design
Swappable roller dies enable production of diverse shutter slat profiles (standard, wind-resistant, anti-theft).
