0.2-3mm High-Precision Slitting Line
The 0.2-3mm high-precision slitting line is controlled by PLC programming, with the touch screen as the human-machine interface, automatic and manual interchangeable settings, with automatic start button, automatic stop button, temporary stop button, emergency stop button, abnormal alarm and other functions, with perfect performance and very advanced. After the manual threading of the steel coil slitting line is completed, the rest of the time the whole line can be in an automatic working state!
Flow Chart Of The Slitting Line
This high-precision steel coil slitting line is composed of main components such as uncoiling, pinch primary straightening, slitting, tensioning, and winding. When the coil slitting machine is working, after the steel coil is installed on the uncoiler, the steel plate is pressed into the pinch and sent to the primary leveling machine. For the material distribution tension station, the strip steel coil is finally coiled by the winder, and then packed and transported out of the production line by the unloading trolley.
Main Machines Of The Slitting Line
1. Hydraulic coil-loading car:
To send coils from coil stock to uncoiler and load the coil onto uncoiling center.
2. Cantilever-mandrel Un-coiler:
The uncoil mandrel segments are teeth shape, square pyramid expansion, hydraulic rotator to supply hydraulic oil to hydraulic cylinder for expansion.
3. Double-roller pinch feeder & Five-roller Leveler and Shear:
Function: pinch feed steel strip into first pit loop, level the strip to be flat, cut off irregular strip head.
4. Pit Loop 1:
Function: to synchronize the speed of pinch feeding and leveling speed and slitting speed by detecting position of steel strip in loop.
5. Side Guide:
Structure: vertical rollers to restrict the progressing position of strip, while horizontal rollers to press strip.
6. Disc Slitter Machine(double heads):
Disc cutters circle slitting spindles tight, and the spindle is installed on support stand.
7. Scrap reeling:
Function: to wind up and collect edge scraps of slitting.
8. Pit Loop 2:
Function: to synchronize the speed of slitting speed and recoiling speed by accumulating steel strip in loop.
9. Pre-separator and tensioner:
It is composed of twice pre separating, press roller, tensioner, pinch rollers, shear, deflector roller, base, etc.
10. Re-coiler and separator:
Hydraulic expansion mandrel: gripper clamps strips heads, hydraulic cylinder pull the wedge sliders around main shaft to move and thus outer segments expand.
11. Hydraulic system, Pneumatic system:
Hydraulic system is composed of hydraulic station and hydraulic accessories like valves.
12. Electric Control System:
Automatic running of the whole line is by Siemens PLC control.
