High-Speed Leveling for Motor Laminations
A high speed loop straightener feeds thin lamination stock at high rates. The Jingcui JRS Series handles 0.1 to 1.0 mm silicon steel and similar material. It reaches a maximum feeding speed of 60 m/min.
This straightener adds a buffer loop between decoiling and feeding. The loop keeps the press and feeder fully synchronized at high speed.
What Is a High Speed Loop Straightener?
A high speed loop straightener levels thin coil and buffers it in a loop. The loop stores material between the decoiler and the feeder. This absorbs speed changes so the press runs smoothly.
The JRS Series offers two loop types. The S-type uses a longer S-loop for smoother high-speed feeding. The U-type uses a compact U-loop that prioritizes flatness for transformer and motor cores.
Applications
- Motor stator and rotor lamination high-speed stamping
- EI/UI transformer core and reactor sheet blanking
- High-speed blanking of silicon steel, carbon steel, and stainless strip
- Electronics, electrical, toy, and auto-parts continuous stamping
- High-speed straightening for motor stator/rotor and appliance metal stamping
