1. Overview of Roller Shutter Door Roll Forming Machines
(1) Machine Components
Uncoiler: Holds the metal coil (e.g., color steel, aluminum).
Roll Forming Host Uses multiple sets of roller dies to gradually shape the metal strip into the desired profile (e.g., 60-type, 77-type).
Cutting Device: Some automated machines come with hydraulic or pneumatic cutting systems for fixed-length cutting.
Manual Cutting Section: If the machine lacks an automatic cutter, manual tools (e.g., angle grinder, shear) are used for trimming.
(2) Working Principle
1. Feeding: The metal coil is fed into the roll-forming machine.
2. Roll Forming: The metal strip is progressively bent by rollers to form the corrugated or hooked structure of the shutter slats.
3. Fixed-Length Cutting (Optional)**: Automated or manual cutting to the desired length.
2. Methods for Manual Cutting of Roller Shutter Slats**
If the roll-forming machine does not have an automatic cutting function, or if secondary processing (e.g., adjusting width or length) is needed, the following manual cutting methods can be used:
(1) Cutting Tools
Angle Grinder (with a metal cutting disc) - Suitable for fast cutting of metal slats.
Shearing Machine - Ideal for straight cuts with clean edges.
Electric Jigsaw/Hand Saw - Suitable for small-scale cutting but less efficient.
Plasma Cutter (for thick steel plates).
(2) Cutting Steps
1. Measure and Mark
Use a tape measure to determine the required length and mark the cutting line with a pen.
2. Secure the Slat
Place the slat on a stable workbench or clamp to prevent movement during cutting.
3. Perform the Cut
- Use an angle grinder or shearing machine to cut along the marked line, ensuring a straight edge.
4. Deburring
- Smooth the cut edges with a file or grinder to prevent injuries from sharp burrs.
