Ⅲ.Brief introduction 

1. Hydraulic entry coil car                         

The car can move levelly and vertically, which is convenient for putting the steel coils into the de-coiler.  It is driven vertically by hydraulic cylinder with four guide pillars.   

The level movement is driven by cycloid motor .

15T(Max) The capacity it can carry is 15 Tons(MAX)            

2.de-coiler

Support steel rolls and uncoiling.

It can expand and    shrink with hydraulic oil cylinder and fit with the inner hole of the steel coils and is equipped with supporting stand.

Moment motor drives the coils running and the motor can run right and left to prevent the coils running by inertia.

3. Side guide device

It uses the vertical rollers of both sides to guide the plates into the slitting machine correctly.

The guide rollers are adjusted by the rods on both sides . The width range is 500-1250mm.

It is equipped with the hydraulic press and damping device to make sure the slitting precision.

4. slitting machine

Power part: This is composed of power-stand, decelerator, 30KW direct current motor, gear distributing case, coupler, spindle, connecting-cover, etc.

Host machine: This is composed of bottom-stand, fixed bracket, big slide, knife pivot(φ180mm, 2pcs), movable bracket, slide, the front and back adjustable device of bracket, knife pivot lifting and pressing down adjustment device, accompany of blade, separating cover, rubber band and 10 blades with the machine

It change the blades through moving out the bracket hydraulically and is very convenient and fast

5.pre-dividing tension device

It consists of the frame, pre-dividing device, press and tension device and guide rollers and so on. And it is used to adjust the tension of pre-divide and recoiler to make sure the even and tight quality.

6. Hydraulic recoiler

It adopts the hydraulic expand and shrink recoiler shaft to tight the inner hole of coils

It uses the hydraulic movable arm with the supporting spacers to ensure the even recoiling quality.

It is equipped with the push device to help unload the coils

The motor is DC 75KW with 590 controller to ensure the recoiling.

7.Electric control system: electric cabinet and operate table

8.Hydraulic system: hydraulic stand and pipe .etc
