High Speed Precision Slitting Line High Precision Heavy Duty Steel Slitting Machine
China High Precision Heavy Duty Steel Slitting Machine In High Speed
Our high speed steel coil slitting line improves in many parts, can give good stability and precision.
1. 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.
2.Pinch roller plays deflection guide role while pinch feeding, preleveler releases steel sheet internal stress.
3.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.
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 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.
5. Scrap winder: vertical winding or horizontal winding, scrap baller & chopper, optional. for high speed thin sheet usually vertical type.
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.Unloading car can be floor cradle type, with over press arm to keep strips separating, the new steel strips winding can be started while coil unloading car travels slit baby coils out.
