Key Structural Features of the Machine
- Robust Frame Design: The main frame is fabricated from high-strength beam steel and treated with a shot-blasting process immediately after welding to ensure durability and a smooth finish.
- Cantilever Extension Cope Shaft: This shaft, with diameters ranging from Φ465 to Φ515, employs a cantilever-style extension mechanism. It is precisely managed through a valve-controlled hydraulic system, complemented by reliable mechanical components for seamless operation.
- Independent Drive System: The unit functions autonomously, utilizing a chain-driven reducer to rotate the shaft for either uncoiling or recoiling coil stock. In tandem with the forming machine, the decoiler actively feeds the material, with uncoiling speed dynamically regulated by an ultrasonic sensor for optimal synchronization.
- Dedicated Hydraulic Support: A standalone hydraulic system powers and stabilizes all decoiler functions, delivering consistent performance under varying loads.
- Advanced Electrical Controls: An independent electrical control setup allows for effortless extension of the uncoiler’s central shaft, along with precise forward, reverse, and incremental jogging motions to fine-tune operations.
- Efficient Coil Handling: A hydraulic coil cart simplifies the process of loading and unloading coils, minimizing downtime and enhancing workflow efficiency.
- Motorized Head Swapping: The system features automated head changes driven by an electric motor, enabling quick transitions between setups without manual intervention.
