Super High Speed Steel Coil longitudinal Slitting Lines 4 x 1600
180mpm
Our new type advanced longitudinal slitting line gives much
higher speed, stability and precision.
1. Single mandrel decoiler:
press one button on operator panel, centralizing to
easily adjust coil on central line.
If partial coil is slit, the remaining coil sheet can
return back to uncoiler
uncoiler mandrel is zigzag teeth segments to protect
inner steel sheet not bruised.
paper peeling device in front of uncoiler to peel off
wrapped paper.
2.Pinch roller plays deflection guide role and pinch feeding roles.
3.Side guide and horizontal guide: to guide steel strip in center
and not jump up down.
4.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 spacers are available for thin sheet slitting
- slitting tools arrangement program makes slitting accessories
change easy.
- We also give option of 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.
5. Scrap winder: vertical winding reels on ear frame of guide roll
table, the edge scraps itself fall down, and tail press roller hold
slit stips tails.
6. 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.
7. 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.
8. Recoiler: overarm press separator from top to press down
with brusher brushing off strips clean.
triangle door rotating to support recoiler mandrel shaft
firmly and precisely.
Seamless mandrel to protect steel coils inner surface.
9. Hydraulic piping adopts clamp lock type, solid structure and
easy to install and dismantle.
