GLK3-1300 coil feeding line for washing machine parts stamping line.jpg

This is a washing machine parts stamping line from one of our customers which use coil feeding line with a shearing unit.

After the metal coil has been uncoiled, straightened, and fed, a customized hydraulic shearing unit will be used for sheet blanking. After that, a robotic arm picks sheet up to the next station, which will save the cost of a blanking press.

This coil feeding line can process sheet metal thickness from 0.5mm to 4.5mm, and coil width up to 1300mm. With quality designed anti-fatigue and wear resistance spindle, the uncoiler can load metal coil up to 7 tons. Thanks to the pneumatic hold-down arm, pneumatic limiting arm and pneumatic coil inlet swing arm, the metal coil will be well located without strip rebound or swing.

7pcs of straightening rolls are made by high-quality GCr15 steel, and there are also 3 groups of auxiliary support rollers to achieve a precision levelling and avoid coil bending. The metal coil will be lubricated after coming out from the feeding part, then a shearing/cutting unit driven by a hydraulic power will process a smoothly blanking.

Heavy duty thick steel coil feeding line uncoiler straightener feeder GLK5-600

coil feeding line for material 9mm.png

This is a heavy duty thick steel coil feeding line, uncoiler straightener feeder machine GLK5-600. It can process steel thickness from 0.8mm to 9.0mm, metal coil width up to 600mm.

With loading capacity 5ton, the movement of the travelling coil car is driven by hydraulic motor. A hydraulic cylinder will help the coil car lift up and down smoothly. There are 2pcs of support rollers in coil car to support uncoiling process for thick steel.

With HongEr designed uncoiler spindle, the mandrel is expanded by a hydraulic cylinder with automatic centring. The air operated hold-down arm and width limiting are electric control with pneumatic cylinder drive. With pneumatic disk brake and photoelectric sensor loop control, the uncoiler part can coordinate with servo straightener feeder part very well.

Coil levelling is processed by high-quality straightening rolls with hardness in HRC60, as well as support rollers strength precision straightening performance and prevent coil bending. With automatic straightening valve adjustment and automatic coil feeding line height adjustment, the operator can handle this coil feeding line easily by Mitsubishi touchscreen panel.

We also provide lots of optional specification for our customers, such as hydraulic shearing unit, automatic lubrication unit, adjustable coil outlet bracket or conveyors.

To know more details about why HongEr technology can well handling thick steel in 9.0mm thickness, or even in 12.0mm thickness, please contact us to get more technical introductions.
