Zigzag Feeder and Dual-Station Decoiler Enable High-Efficiency Automatic Stamping Line for the New Energy Industry
November 11, 2025
In modern metal stamping production, improving material utilization while maintaining high efficiency has become a key challenge for manufacturers.
The combination of a zigzag feeder with a dual-station decoiler provides an advanced solution for coil-fed stamping lines. This system enables continuous production, reduces material waste, and enhances automation — making it an ideal choice for high-volume stamping applications.
The dual-station decoiler (also known as a dual-mandrel decoiler) adopts a dual-spindle expanding drum design, allowing two coils to be loaded simultaneously.
While one side is operating, the other side can be loaded with new material using a forklift or overhead crane — eliminating downtime for coil replacement and ensuring uninterrupted coil feeding.
Each spindle is driven by a vertical motor through a reducer and chain transmission system. Independent contact-sensing control prevents material surface scratches during decoiling.
An optional frequency inverter allows adjustable speed control to reduce coil vibration, while a hydraulic expansion system ensures stable clamping for heavy coils over 2 tons.
Operation is simple and efficient — all functions such as coil tightening, pressing, and spindle rotation can be automatically performed via the touch screen control panel.
The NC zigzag feeder achieves alternating dual-axis feeding, allowing circular blanks to be punched in an overlapping pattern (circle-to-circle cutting). This design significantly improves raw material utilization and minimizes waste.
Based on the blank diameter, the feeder automatically calculates shifting distances and feed steps to optimize the material layout. Even when blank sizes vary, the system automatically adjusts the feeding path and angle.
Equipped with a Mitsubishi PLC and dual Yaskawa servo motors:
One servo motor drives the feed rolls through a synchronous belt for accurate feeding.
The second servo motor, combined with a Hiwin precision ball screw, controls the left-right shifting movement.
Feeding accuracy can be maintained within ±0.08mm, and edge-to-edge spacing within 0.5mm, fully meeting high-precision stamping requirements.
Operators simply input material width, blank diameter, and feed pitch.
The control system automatically calculates movement and feeding distances — no mechanical adjustments required, realizing fully automated operation.
The automatic stamping line integrating Youyi Precision’s NC zigzag feeder and dual-station decoiler delivers a highly efficient, material-saving production mode for manufacturers.
It greatly enhances productivity, reduces coil waste, and minimizes manual intervention.
Moreover, this line can be flexibly combined with stamping robots or progressive dies to achieve multi-process forming operations — realizing a truly time-saving, labor-saving, and intelligent stamping production system.
Zigzag feeding enables optimal nesting of circular blanks, reducing scrap and lowering raw material costs.
Dual-station decoiler eliminates downtime during coil change, ensuring uninterrupted operation.
Advanced servo control ensures accurate feeding and consistent product quality.
Automation minimizes manual operations, improving safety and reducing workforce requirements.
Choosing Youyi Precision’s zigzag feeder and dual-station decoiler line means choosing efficiency, precision, and sustainability in modern stamping automation.
