In the press feeding line, a metal coil will be uncoiled, straightened, and then feed into a stamping press. Consequently, a precision coil feeding line will help you handle various types of coil material in a different situation and improves efficiency.

Applicable Material

• Material Thickness: 0.2-3.5 mm

• Coil Width: 20-800 mm

Press Feeding Line Structure

1. Combined Uncoiler Straightener GL

2. Servo Coil Feeder RNC/NCF

3. Stamping Press 25-250ton

Space-saving and High Synchronization

This line integrates the decoiler and straightener, saving material loop space. It also achieves high synchronization between uncoiling and straightening processes.

Precision Straightening Performance

Equipped with 7 high-quality rollers, the combined decoiler-straightener handles various high-precision straightening needs. For more stringent requirements, the 15-roller version is available. Additionally, for copper or aluminum materials, it features an operable straightening section for easy cleaning and maintenance.

Press Feeding Features

Main Parts in Press Feeding Line

1. Combined Uncoiler Straightener

   
   Both passive and motorized uncoilers are available for different materials: passive uncoilers suit general stamping, while motorized versions apply to thin materials with high surface requirements. For springy coils, a pneumatic pressure hold-down arm is suitable.

All rolls use Gcr15 bearing steel with thick chrome-plated, ground surfaces. Straightening roll pressure is pneumatic with worm wheel adjustment for precise, smooth feeding.

2. Servo Coil Feeder

   
   With modular design and computer control, HE servo feeders are easy to install, intelligent to operate, and feature precise feeding, low noise, and easy maintenance. The upper roller release system is pneumatic, reducing feeding errors during press feeding. Yaskawa or Siemens servo systems are optional, delivering ±0.1mm feeding accuracy and max speed 20m/min.

3. Gap Frame Press APA

   
   The press body uses high-quality stress-relieved welded steel, ensuring stable, reliable stamping precision. It features a symmetrical design with two slide boards and a balancer for stable, smooth operation. Crank, gear, and rod undergo oxidized hardening and grinding for durable performance. High-strength clutch, brake, double solenoid valve, and overload protector ensure safe operation.
