Full automatic CRGO cut-to-length line

I Description
This line is digital control cut-to-length, servo motor feeding; By choosing CRGO strip shape on the touch screen and inputting dimension, the line will automatically punch and cut strips. There are “two punch + two cut” line and “one punch + two cut” line. Transformer lamination strip shapes can be as below:

transformer lamination strips can be cut by full automatic CRGO cut-to-length line

II Main features

- Full automatically, from decoiling to stacking, only three operators are needed

- Good & reliable punching/shearing power: imported hydraulic servo control, quick speed, low noise and long life

- Good & reliable feeding power: big torque AC servo motor, quick responding, high positioning precision, low noise, low braking heat loss, long life

- Track positioning: servo motor pulling ball screw, linear guide positioning, quick, accurate, convenient; automatically memberizing track width.

- Movement control: adopts advance PCC controller, Ethernet Powerlink communication technology, massly reduces wire connection and so raise the reliability, stability and realtime ability of the system; remote control and diagnosis

- Simple & intuitive operation: choose strip shape and input sizes and dimensions on the touch screen

- Adopts inverted-support collecting method which can collect and order 5m long strips and reduces the vibration, thus reduces affects to magneting performance of CRGO strips during processing.

- Equipped with Step-Lap function, step-lap quantity can be 7.

- Imported world famous brand parts, such as linear rail, ball screw, bearings, etc., assure machine long life

- New improved COLUMN-STACKING function, five columns (two yokes, two side limbs and one center limb) can be stacked automatically. Stacking precision +/-0.3mm.
