Enhancing Decoiler Machine Capabilities

Decoiler machines have been integral to the stamping automation industry for their efficiency and precision. To cater to diverse production requirements, multiple optional devices, such as pressing and supporting arms, are designed to augment their performance. This article delves into the practical functions of these arms and their significance in enhancing the versatility of decoiler machines.

The Pressing Arm: Ensuring a Smooth Decoiling Process

The pressing arm plays a crucial role in the decoiling operation by clamping the strip material, preventing it from becoming loose. It consistently applies compressive force, which guarantees a seamless decoiling process. This optional device is particularly useful for material strips with thicknesses exceeding 2.0mm and large widths.

The Supporting Arm: Achieving Stable Feeding and Reducing Edge Scratches

On the other hand, the supporting arm is designed to lift the material head after it has been uncoiled. This arm works in tandem with the leveling machine to ensure stable feeding and minimize the risk of edge scratches on the strip material. Like the pressing arm, the supporting arm is primarily employed for thicker and wider material strips.

Combining Pressing and Supporting Arms for Maximum Efficiency

When a decoiler machine is equipped with both pressing and supporting arms, it is typically integrated with a thick plate leveling machine or a leveling feeder to form a two-in-one or three-in-one system. The following steps outline the operating procedures for these configurations:

  1. Position the Arms: Raise the pressing arm and lower the supporting arm to facilitate material loading without any interference during the winding process.
  2. Adjust the Expansion Drum: Press the hydraulic expansion button on the uncoiler’s handle to adjust the drum to a smaller diameter than the material coil’s inner diameter.
  3. Load the Material Coil: Use a crane or forklift to mount the material coil onto the expansion drum, then expand the drum to secure the material and position it near the retaining arm’s inner side.
  4. Clamp the Material: Lower the decoiler machine’s left and right retaining arms to clamp the material.
  5. Engage the Pressing Arm: Lower the pressing arm, ensuring its wheel firmly contacts the material coil’s outer circle.
  6. Position the Material Head: Switch the electrical control box to manual inching operation, run the decoiler machine, and raise the supporting arm to support the material coil. Safely cut the binding strap using scissors.
  7. Feed the Material: Unwind the material and use the leveling machine’s hydraulic feeding guide device to bend the material head, allowing it to enter the feeding roller smoothly.
  8. Advance the Material: Utilize the decoiler machine’s power and the material’s “inching” and “retraction” to continuously advance the material, bending the material head to enter the leveling roller.
  9. Clamp and Release: Press down on the front feeding roller to clamp the material, then lower the supporting arm and hydraulic feeding guide device.
  10. Complete the Setup: Operate the leveling machine’s manual inching button to pass the material through the leveling roller and feed it into the feeder, preparing the entire machine for automatic feeding.

Expanding the Horizons of Decoiler Machines

The addition of pressing and supporting arms to decoiler machines significantly expands their applicability in various stamping automation production scenarios. These optional devices not only optimize the decoiling process but also enhance the overall efficiency and versatility of the machines, making them indispensable tools in the industry.
