Loading Unloading Floor Cradle Coil Car Thin Sheet Steel Slitting Line
Our high speed steel coil slitting line specially suit thin sheet steel slitting, improves in many sides and gives good stability and precision during slitting.
1. Coil loading car, unloading car can be floor cradle type, the rails sit on ground not like pit type coil car sits on rails in pit.
Moreover, the cradle unloading car has separator overarm to press slit baby coils without strapping packed on recoiler mandrel.
Recoiler press separator separates slit coils on recoiler, the separator overarm press on slit coils from another angle, recoil mandrel shrink, hydraulic pusher push and cradle support slit baby coils comes out from recoiler mandrel and send the coils onto arm of turnstile with another separator arm press on slit coils, waiting for strapping packing and discharging by forklift or crane.
2, Single mandrel decoiler: press one button on operator panel, centralizing to easily adjust coil on central line.
mandrel is interlace teeth segments, good for thin sheet coil inside.
3.Pinch roller plays deflection guide role while pinch feeding, preleveler releases steel sheet internal stress.
4.Side guide unit: add 1 over 2 rollers, pneumatically press down upper roller, to guide steel strip from side and up-down direction before slitter.
5.Slitter:
6. Scrap winder: vertical winding or horizontal winding, scrap baller & chopper, optional. for high speed thin sheet usually vertical type.
7. Pre separating and tensioner: all separating shafts are the same and easily dismantled and installed.
tension provision is variable piston pump hydraulic system,two hydraulic cylinders on top give balance pressure.
8. Post shear and Deflector roller: post shear cut off irregular strips tails,making packing on recoiler easier.
Encoder on deflector roller track the slitting length and shows on touch screen.
