Super Speed Precision SUS Steel Coil Slitting Lines Machine 3 X 1600 3mm
Precision Super Speed SUS Steel Coil Slitting Lines Machine 3 X 1600
Process:
Coil saddle, Coil-loading——Double mandrel uncoiling——Coil-head-feeding, press & shoveling——Double-roller pinch feeding, five-roller leveler——End-cutting----transmission roll table ---- Side guide----Disc slitting——Scrap reeling——Hole Accumulator—— Pre-separator/Tensioner/post shear/length-measuring roller——Coils press & separator/recoiler —— Coils-discharging——Hydraulic control——Electric control

Composition
| Characters and Parameters | |
| Coil Cars | Welding boy, V saddle, four pillar guide, hydraulic up-down, motor drive walking |
| Uncoiler | Single expansion teeth staggering mandrel, AC motor gear transmission uncoiling back tension, hydraulic central aligning, paper peeling |
| Coil head opener | Snubber roll, straightening roll and shoveling plate |
| Preleveler | Double pinch rolls and 2 over 3 leveler to straighten coil plate, and a hydraulic shear |
| Loop pit | One pit situated after preleveler and before slitter, the other pit after slitter and before tension, to synchronize steel strip |
| Side guide | To ensure steel strip in center of the line before slitting |
| Slitter | Double arbors, the upper arbor up-down adjusting, motor and gearbox drive universal joints, need disc knife, spacers, PU rubber, bakelite strip plates tooling. |
| Scrap winder | Double winders at ear of the line, either horizontal or vertical, AC frequency controlled, with strips checking table and pressing roller |
| Tensioner | Felt press tension, encoding deflector roller |
| Separators | Twice separators before tension, Hydraulic press separator frame on recoiler |
| Recoiler | hydraulic expansion recoil mandrel, motor and gearbox drive, hydraulic coils pusher, swaying door support |
Optional:
Double slitters for fast change: each slitter is movable and can exchange with each other fast. The slitter is composed of fixed stand, movable stand, double knife shafts, upper shaft press down mechanism, etc. The movable stand is at operation side, walk out on linear rails to let operator change knives.The two slitters crosswise move on rails from online position to exchange platform or from platform back to online, the platform moves longitudinally to exchange two slitters positions.
Slitting tools:
knife: D350×d220×T15mm, H13K, HRC59-62
Separator: Φ200×Φ100×3mm, 65Mn quenching treatment
Separate nylon: Φ140×Φ100
