Ⅲ.Description of the whole machine line

3X1250mm steel coil slitting line is used for slitting the carbon plate to prepare for the next process.

1.Hydraulic 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.

◆The capacity of it can reach to 15Tons(MAX)

2.Hydraulic cantilever de-coiler

◆Support the steel coil and de-coiling. And is equipped with the supporting stand

◆It can expand and shrink with hydraulic oil cylinder and fit with the inner hole of the steel coils.

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

3.Press and pinch and feed device

◆It is good for improve the plates' surface and do straight then guiding the steel plates into next process.

◆It is made by 5 leveling rollers , drive device , 2 pinch roller and frame. Every rollers is the main driving rollers.

◆The gap between rollers can be adjusted manually to make sure the leveling quality.

4. Hydraulic cutting machine

◆it is used to make the plates easy to the next process by cutting the head even.

◆t can also use to make the big coils cut to length into several small coils.

5. Looper Ⅰ

◆It uses the 2 groups of magic eyes to control the speed buffer between decoiler and slitting machines

6. slitting machine

◆Power part: This is composed of power-stand, decelerator,45KW 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(φ200mm, 2pcs), movable bracket, slide, the front and back adjustable device of bracket, knife pivot lifting and pressing down adjustment device, accompany of blade, shim, rubber band and so on

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

7.Scrap winder

◆It consists of base, the shaft and plate of scrap material, friction wheel, supporting wheel chain, chain, decelerator and motor.

8. Looper Ⅱ

◆It is equipped with the bridges which is driven by hydraulic. When feeding the head of the coils, the bridge can lift up and be a surface to make the plate easy into next progress, once finished the feeding period, the bridge will lift down to create the buffer zone to store enough plates and ensure the recoiling quality

9.Tension stand

◆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.

10. 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 80KW with controller to ensure the recoiling.

11. Hydraulic unload car

◆This car carries the slitted coils and movable lift

• Electric control system: Electric cabinet and operate table

◆Adopt the OLU 590control mode and PLC control mode, It is controlled by LCD screen with fixed-length cutting by codes and count automatically.

13. Hydraulic system: Hydraulic stand and pipe .etc

◆Ensure the using of every hydraulic part.

◆6.3-16Mp The working pressure of the hydraulic system is 6.3-16Mpa
