The following case is one of our customized coil feed solutions that combine 2 in 1 uncoiler-straightener GL-600H and a servo feeder NCF-600H for a stamping blanking production line.

The general process of blanking production or progressive die stamping line is:

  1. Coil loading on trolley
  2. Coil loading to decoiler part
  3. Decoiling and threading
  4. Straightening
  5. Feeding
  6. Stamping blanking or progressive die stamping

Here we take a brief introduction of the uncoiler straightener feeder coil feed line for your reference:

The loading trolley is a device that helps the coil loading to the main shaft of the uncoiler. When starting operation, the lifting part rises so that the center of the coil and the uncoiler are at the same height. After that, the metal coil is driven at a right angle to the feeding direction, and the coil is sent to the uncoiler. In addition, the loading trolley is also used to prevent the coil from falling when the front end of the coil is connected to the leveling feeder.

The uncoiler expands the tiles on the main shaft by hydraulic power to support the inner diameter of the coil and is fixed on the main shaft of the uncoiler. During the operation of the production line, the spindle rotates the uncoiled material according to the control command of the material ring. And the main shaft rotates according to the control command of the material loop and realizes the automatic adjustment of the discharging speed.

After decoiling, the material can be raised manually. First, the coil head can be clamped with the support arm, and then the coil head can be guided from the unloader to the leveling wheel smoothly, easily, and safely. Then straighten the material to flatten its surface, and feed the coil according to the set length and speed.
