Line composed by:

Coil cradel→Uncoiler+ Hydraulic support→Coil opening device and entry table (optional）→Hydraulic loop bridge→Strip guiding device→Main leveling machine→Shearing machine→Conveyor belt (optional）→stack device (optional）→Hydraulic system→Pneumatic system→Electrical control system

Ⅲ.  Main parts and brief description

1.   Coil cradle

Hydraulic lifting, mechanical walking, loading ≤8t  

      
                          Coil Cradle                                       Uncoiler   

2.  Uncoiler

Cantilever type, hydraulic powered, radial expansion mode

3.  Coil opening device and entry table(optional)

Coil opening device peels the coil leading edge with a rubber roller, and then lead the edge into the entry table where rollers pinch and draw the strip forward.
     

4.  Hydraulic loop bridge

The loop bridge leads the strip over the loop pit to reach the equipment over the other side of the pit. When this job is done, the bridge drops down.

5.  Strip guiding device:

To prevent the strip from deviation. It guarantees the strip go on the right course.
    

6.  Main leveling machine

Leveling machine is four-high structure, 11 rollers, with 2 additional drawing rollers. The material of leveling rollers is 42CrMo, quenched and tempered to HRC50 - 55.

8.   Shearing machine

With 2x1500 mechanical shearing machine

9.  Conveyor belt (optional）

10.  stack device (optional）

Pneumatic powered, with width and length readjusting device, hydraulic scissor lift, work piece outlet cradle.

11.  Hydraulic system

Equipped with 4KW motor, 10L plunger pump. The highest pressure designed is 25Mp, and normal work pressure≤15MP.  Main hydraulic cylinder is made with imported seal rings. 

12.  Pneumatic system

Consists of air service FRL, solenoid valve, pipes and cylinder etc. 

Note: air supply unit not included

13.  Electrical control system

PLC and frequency converter controls the whole line. Touch type screen display. Length of sheets and number of sheet to cut can be programmed. Both automatic and manual modes are available. Under automatic mode, the computer monitors the work of the whole line. Error compensation function is available.
