Zigzag Feeder and Dual-Station Decoiler Enable High-Efficiency Automatic Stamping Line for the New Energy Industry
November 11, 2025
The automatic stamping line composed of a zigzag feeder and a dual-station decoiler is a widely adopted solution in the stamping industry.The zigzag feeder allows flexible left-right shifting to maximize material utilization, while the dual-station decoiler alternates between two coil mandrels to minimize downtime during coil changeover.
This combination forms an efficient automatic coil feeding and stamping system that not only realizes continuous automation but also reduces raw material waste, providing a cost-effective and intelligent production solution.
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.
Choosing Youyi Precision’s zigzag feeder and dual-station decoiler line means choosing efficiency, precision, and sustainability in modern stamping automation.
