High-Precision Fineblanking Feeding Line for Thick Plate Coil Processing
August 20, 2025
Fineblanking technology was developed to meet the high precision requirements of stamped parts, particularly the smoothness of cut surfaces. With the rapid growth of the automotive industry, fineblanking is now widely applied to thick plate and cold-rolled coil materials for producing complex multifunctional components.
Compared with conventional stamping, fineblanked parts offer smoother cutting surfaces, higher dimensional accuracy, and superior flatness. After simple deburring, they can be directly assembled, significantly reducing production steps and saving labor and costs.
To achieve continuous and stable fineblanking, a high-precision Fineblanking Feeding Line is essential.
Youyi Precision Automation provides a complete Fineblanking Feeding Line designed specifically for thick plate coil processing. The production line consists of:
Automatic decoiler with loading car
Heavy-duty straightener
L-type lifting platform with discharge support
This feeding line is suitable for processing a variety of coil materials, including cold-rolled steel, pickled steel, galvanized steel, stainless steel, alloy steel, and low-carbon steel.
Material specifications:
Thickness: 2.0 mm – 8.0 mm
Width: 40 mm – 600 mm
Coil weight: up to 3.5 tons
The loading car ensures safe and stable coil transfer to the decoiler spindle. Equipped with an anti-tilting device, it guarantees higher operational safety.
The decoiler secures the material and gradually guides the coil head into the straightener for automatic uncoiling. The system includes:
Main frame
Expanding mandrel
Pressure arm
Coil stopper arm
Disc-type hold-down arm
The straightener works with the decoiler to flatten thick coil materials. After straightening, the sheet passes through a transition bridge to the feeder.
With a 6-over-7 roller design, the straightener ensures smooth and flat material without surface indentation or damage.
After straightening, the sheet is lifted by the L-type platform and fed into the fineblanking press feeder.
The platform is equipped with a laser detection tracking system, which controls start/stop functions and synchronizes feeding speed with the fineblanking press. This ensures efficient and accurate operation.
The Fineblanking Feeding Line for thick plate coil processing provides a reliable and high-precision solution for fineblanking presses. By combining an automatic decoiler, heavy-duty straightener, and L-type lifting platform, it ensures stable feeding, protects material quality, and improves production efficiency.
At Youyi Precision Automation, we are committed to delivering advanced coil handling and press automation solutions tailored to your needs.
