What Is a Metal Coil Cut to Length Line?
A metal coil cut to length line is an automated production system that converts a continuous metal coil into flat metal sheets with customized lengths.
Unlike traditional manual cutting methods, the complete process can be integrated into one production line. The metal coil is loaded onto the decoiler, leveled to remove coil memory and deformation, accurately measured, and then cut into individual sheets.
Depending on the production requirements, the line can be configured with different coil widths, thickness ranges, cutting methods, speeds, and automation levels.
How Does the Metal Coil Cut to Length Line Work?
A typical metal coil cut to length line consists of several key sections:
1. Hydraulic Decoiler
The decoiler supports and unwinds the metal coil continuously. A hydraulic expansion system can provide stable coil feeding and improve production efficiency.
The capacity of this decoiler is 10 tons.
2. Straightening and Leveling System
The leveling machine removes bending, wave, and residual stress from the coil. This ensures that the finished sheets are flat and suitable for further fabrication.
Driven by servo motor. It is fast speed and more accurate.
3. Shearing System
The cutting unit separates the continuous strip into individual sheets according to the preset length. Different cutting configurations can be selected based on material thickness and production speed.
4. Automatic Stacking System
After cutting, the finished sheets are automatically collected and stacked neatly. This reduces manual handling and makes subsequent packaging and transportation easier.
