Coil Feed Features in Circle Blanking Line

Zigzag circle blanking line to improves production efficiency

Most of the coil feeders are one-way feeding. In other words, it forwards in one direction, and quantitative step feeding. However, after metal strip feeds in one direction by these coil feeders, the edge material left after the circle blanking line is broad and challenging to reuse. Consequently, it is low utilization and massive waste in the metal stamping process.

One the other hand, HE zigzag coil feeder has two-way travel. And based on different circle sizes, it adjusts the feeding length from the horizontal or vertical direction. As the distance of each circle can set in 0.5mm, and each feeding accuracy will keep in 0.08mm. So, it will save material 7% in each feeding movement.

For example, in the case below, it will save 10% of the material cost.


Main Parts in Circle Blanking Line

The most common uncoiler in the circle blanking line is standard motorized uncoiler.

Firstly, HE-machine provides both hydraulic expansion uncoiler and manual expansion uncoiler depends on specific coil weight. Secondly, the uncoiler will equip a pneumatic coil hold-down arm for some springy steels.

Meanwhile, for the product that has a higher straightening request in the circle blanking line, HE recommends the combined decoiler straightener machine.

It has precision straightening performance and also saves workspace. And please check the decoiler straightener equipment page for full details.

A touch screen sets all the zigzag parameters, which is easy to learn and operate. That is to say, after put in the circle diameter and feeding times, the machine will work automatically. Please check the zigzag feeder equipment page for full details.
