The decoiler serves as a vital auxiliary device in automating the processing of coiled sheet metal, making it an indispensable component for achieving full automation in stamping production. Among the various types of decoilers available, the hydraulic decoiler stands out for its exceptional load-bearing capacity, high level of customization, and broad applicability.

Unlocking the Potential of Hydraulic Decoilers

Ordinary decoilers rely on manual expansion with four supporting tile plates to bear the weight of the coil. While this approach is widely used and proven effective, industries such as automotive and hardware processing often deal with wide and heavy coils. In such cases, hydraulic decoilers are the go-to solution. By utilizing hydraulic expansion instead of manual methods, these decoilers offer better handling of heavy materials.

However, employing hydraulic expansion introduces new challenges that need to be addressed to optimize the unwinding process fully:

  1. Ensuring Stable Unwinding: Heavy sheet metal or excessive unwinding can cause sagging between the production line’s main unit and the decoiler, leading to poor unwinding stability and potential coil issues, impacting material quality and equipment lifespan.
  2. Enhancing Safety Measures: Guards are needed to prevent the coil from being thrown out of the spindle during unwinding, but their installation can be complex, and safety factors need improvement.
  3. Streamlining Coiling Device Automation: The coiling device used in conjunction with the decoiler requires manual intervention, which is time-consuming and labor-intensive, calling for a more automated and efficient approach.

Introducing the Large-Tonnage Hydraulic Decoiler

To tackle these critical issues, experts have developed and produced a large-tonnage hydraulic decoiler with remarkable features that offer significant performance advantages:

  1. Stabilizing Unwinding with Pressure Arm: The pressure arm applies force during the material unwinding process, ensuring stable unwinding and preventing loose coils. The combination of pneumatic blocking arms and supporting arms effectively resolves sagging issues during feeding.
  2. Reducing Friction with Positioning Columns: By setting up positioning columns, a gap is created between the coil and the backing plate, minimizing friction during unwinding and ensuring a steady material flow.
  3. Automated Material Loading: A hydraulic material loading trolley enables automated, safe, and convenient material loading, streamlining the entire process.
  4. Enhanced Safety with Pneumatic Blocking Arm: An innovative pneumatic blocking arm replaces the traditional A-type iron, effectively restraining the coil and preventing it from rushing out of the spindle. This enhancement significantly improves the safety of the unwinding process and simplifies loading steps.

Effortless Unwinding with the Large-Tonnage Hydraulic Decoiler

Using the large-tonnage hydraulic decoiler is a straightforward and efficient process:

  1. The coil is placed on the hydraulic material loading trolley.
  2. The height of the support mechanism is adjusted using hydraulic cylinders.
  3. The motor is activated, and the sliding seat moves on the slide rail, guiding the coil to the outer edge of the decoiler’s spindle, and leading out the leading end of the coil.
  4. The pneumatic blocking arm’s material blocking device is positioned in the slot.
  5. The decoiler’s pressure roller is engaged with the coil using a cylinder.
  6. The decoiler motor is started, initiating the unwinding process.

In conclusion, the large-tonnage hydraulic decoiler offers remarkable advantages over traditional decoilers in terms of stability, safety, and automation. By investing in this advanced technology, you can streamline your stamping production, enhance efficiency, and improve overall productivity. Embrace the power of hydraulic decoilers to stay ahead in the competitive world of metal processing industries.
