High Speed Precision Steel Slitting Lines Thin Gauge Sheet Slitting Machine

High Speed Precision Steel Slitting Lines For Thin Gauge Sheet

Thin sheet slitting machine need high speed slitting 120m/min, 150m/min, 200m/min, thus about half an hour can slit one coil, plus 

effective mechanism is arranged to shorten down time, the time of loading, threading and unloading can be finished within 10minutes, each 8 hour can slit 10coils (10coils x 15T = 150T).

Characters:

1. Coil storing saddle: put coil ready on the saddle, coil car (trolley) can come under the coil and lift it up, which reduces overhead crane working time and avoid steel coil being damaged if crane directly put coil on coil car.
2. Coil loading car: either floor type coil car or pit type, ensure efficient coil loading onto uncoil mandrel.
3. single mandrel uncoiler: hydraulic expansion mandrel proper for 508mm, and can install additional segments or rubber sleeve to uncoiler bigger ID coils. The load on mandrel varies with different dimensions metal coils.
4. coil head traction press arm, peeler shoveling plate: cooperate with each other to open coill head and send into pinch feeder.
5. Pinch feeder and preleveling equipment: in threading send coil head forward to slitter, in automatic mode, synchronous with slitter continuously sending strip into accumulator loop.
6. 1# first accumulator loop in ground: hydraulic flapping plate as bridge to let thin sheet pass over during threading stage, in automatic mode, accumulate steel trip in loop pit to synchronize pinch feeding and slitting speed, with electric eyes on pit walls to feedback.
7. Press rollers and side guide: to horizontally and vertically guide steel strip on center of slitting machine. Manually adjust side guide to steel strip width.
8. Main machine, slitting machine: include a pair of parallel knife shafts, one moveable slitter stand, one fixed slitter stand, screw down mechanism, drive and transmission controlled by DC / AC driver.
9. Edge scrap coiler: wind up edge scrap, winding tension is provided by cycloid motor through friction wheel.
10.  2# accumulator loop pit: the same structure with 1# accumulator pit, to guarantee synchronous speed of slitting and recoiling, the slit strips never ever entangle in the loop.
11. Tension and speed measuring unit: hydraulic wool felt type or roller type tension provision of recoiling, encoding measure line speed before recoiling.
12. Deflector roller and pre separator: before recoiling, separate steel strips in order and guide strips direction to recoil mandrel nipper.
13. Separating overarm and recoiler: either seamless or open segments mandrel, to make sure good recoiling, coiling hump ≤0.5mm, edge difference ±0.10mm.
14. Electric control system: Siemens PLC to control the slitting line working at high speed 200m/min.ü
