3. Working Process of the Automatic Cut-to-Length Line
The Automatic Steel Coil Cut-to-Length Line integrates multiple processing sections into one continuous production system. The material moves from right to left through the following working process:
- Hydraulic Entry Coil Car
- Hydraulic Cantilever Decoiler
- Press and Side Guide Device
- Precision Leveling Machine
- Encoder and Fixed-Length Measuring Device
- Hydraulic Guillotine Shearing Machine
- Receiving Table and Hydraulic Stacker
First, the hydraulic loading car lifts the steel coil and transfers it to the decoiler. Next, the hydraulic expansion system secures the coil and prepares it for uncoiling.
Afterward, the steel strip passes through the pressing and guiding mechanism before entering the leveling machine. The multi-roller system straightens the material and improves its flatness.
Meanwhile, the encoder measures the feeding distance and sends signals to the PLC control system. Once the preset length is reached, the hydraulic shear cuts the steel sheet automatically.
Finally, the finished sheets are transferred to the receiving table. The hydraulic stacking system and pneumatic alignment devices help arrange the sheets into neat piles, making subsequent transportation and storage more convenient.
4. Main Components of the Steel Coil Cutting Machine
4.1 Hydraulic Entry Coil Car
The Hydraulic Coil Loading Car is designed to transport heavy steel coils from the storage area to the hydraulic decoiler. It features horizontal movement and vertical lifting functions, making coil loading and unloading more convenient.

- One hydraulic lifting cylinder.
- Four balance guide pillars for stable lifting.
- Hydraulic-driven vertical movement.
- Motor-driven horizontal movement.
- Independent auxiliary control panel.
- Ability to return unfinished coils to the initial position.
The hydraulic lifting system raises the coil to the required height, while the motor-driven carriage moves it toward the decoiler mandrel. Once the coil is secured, the loading car returns to its original position.
4.2 Hydraulic Cantilever Decoiler
The Hydraulic Steel Coil Decoiler supports large steel coils and provides stable material feeding during production. Its hydraulic expansion mechanism accommodates coil inner diameters ranging from Φ508 mm to Φ610 mm.
Main features include:

Furthermore, the hydraulic expansion system securely holds the coil during operation. The driving motor supports controlled rotation, helping maintain stable steel strip feeding into the following processing sections.
4.3 Four-Fold Precision Leveling Machine
The Steel Sheet Leveling Machine is an important part of the production line because it removes coil curvature and improves material flatness before shearing.
Steel coils may develop residual stress, bending, and deformation during manufacturing, transportation, and storage. Therefore, precision leveling is necessary to prepare the material for accurate cutting and downstream fabrication.
The machine adopts a multi-roll leveling structure with a 55 kW AC driving motor.
