Wedge Type Hydraulic Decoiler

I. Purpose and Characteristics
The Wedge-Type Hydraulic Decoiler employs a wedge-type expansion mechanism, delivering an expansion force that is over 30% greater than that of traditional designs. It is ideally suited for decoiling heavy-gauge plates with coil weights exceeding 10 tons and widths greater than 1.5 meters. This wedge-type hydraulic decoiler is widely utilized in production lines involving high-strength materials, such as those for automotive chassis beams, steel structures, and shipbuilding. The equipment integrates hydraulic expansion, variable-frequency active feeding, and PLC-based tension control. By choosing the Wedge-Type Hydraulic Decoiler, users can effectively resolve critical issues associated with heavy-load operations-specifically, the slippage of sector plates or uneven expansion.

II. Structure and Operation
The machine body features a thick-walled, welded box-beam construction. The gearbox utilizes forced lubrication and is paired with a closed-loop oil circuit driven by dual constant-speed motors. Internally, the Wedge-Type Hydraulic Decoiler's mandrel employs a wedge-type slider mechanism: four sector plates engage with wedge blocks via angled dovetail slots. A hydraulic cylinder located at the tail end pulls a square-section shaft, causing the wedge assembly to shift axially; this axial movement drives the sector plates to expand or retract radially. This structural design possesses strong self-locking capabilities, ensuring uniform clamping even when the inner diameter of the coil material exhibits significant dimensional deviations. A hydraulic support arm is positioned at the front of the coil drum, and the entire machine frame is capable of hydraulic lateral shifting. A variable-frequency motor drives the coil drum shaft, achieving a maximum decoiling speed of 25 m/min. During decoiling operations, the Wedge-Type Hydraulic Decoiler's external support bearing automatically engages to provide firm bracing, thereby further minimizing cantilever deflection.

III. Customization and Service
The mandrel length, expansion range, and supplementary sector plate kits can be customized to meet specific requirements regarding coil weight and width. The Wedge-Type Hydraulic Decoiler is available for order starting from a single unit, with color customization options available. Payment terms typically require a 30% upfront deposit and a 70% final balance; trade terms include EXW, FOB, and DDP. The product comes with a one-year warranty and undergoes rigorous testing and acceptance procedures prior to leaving the factory. Installation guidance is available either on-site or via video conferencing, and third-party inspections are welcome. Packaging options include bare shipment or wooden crate packaging. Choose the Wedge-Type Hydraulic Decoiler for a stable and reliable solution for your heavy-load decoiling operations.
