Thin Sheet Steel Slitting Lines Loading Unloading Floor Cradle Coil Car

Thin Sheet Steel Slitting Lines Loading Unloading Floor Cradle Coil Car

Our high speed thin sheet steel slitting line has many advantages 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.Slitter:

• high precision tools Disc slitting knives: SKD-11, HRC 60-62, knife thickness tolerance within ±0.003mm.
• PU circled disc spacers: the same precision as knife as spacer and also as knife cushion.
• wood plates cushions to guide steel strips are available for thin sheet slitting
• double slitter heads automatic exchanging with each other on exchange base, one slitter is working online while workers can arrange knife tools on the other slitter, automatically check arranged knife clearance.
• Rotating turret for tools changing, two pairs of cantilever shafts, one pair for receiving old tools, the other pair for installing new tools, the tools arranging is offline, not bothering inline working.

4. Scrap winder: vertical winding or horizontal winding, scrap baller & chopper, optional. for high speed thin sheet usually vertical type.
5. 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.
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.
6. Recoiler mandrel is seamless segments, separator is frame type with press separator shaft falling on slit strips guided by pillars, soft wiper is available.
