Automatic Cut To Length Line for Steel Coil, up to 1,250 mm Wide | Nantong Super, Nantong, China

Nantong Super's Automatic Cut To Length Line for Steel Coil uncoils, levels and shears carbon, cold-rolled, hot-rolled, stainless and galvanised steel coil into flat sheets of a set length. It handles material up to 2 mm thick and 1,250 mm wide.

The line is fully automatic. A servo-driven feed gives precise length control, a PLC with an LCD screen counts and cuts to the programmed length, and a pneumatic stacker piles the finished sheets.

Key Features

• Hydraulic entry car moves coils horizontally and vertically onto the decoiler
• Cantilever decoiler with hydraulic expansion and a 40 N.m torque motor for forward, reverse and tensioned uncoiling
• Pre-leveling machine with 19 rollers, hydraulic press and pinch device at the entry, and electrically adjusted roller gap
• Loop pit absorbs speed differences between the leveling and cutting sections
• Side guides with lead-screw adjustment keep the strip aligned into the straightener and shear
• Hydraulic cutter shears from top to bottom, triggered by the feeder signal
• PLC control with fixed-length cutting by code and automatic counting
