3. Description of the whole machine line

ZJX-4*1600mm steel coil slitting line is used for slitting the carbon plate to prepare for the next process.

a. 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

b. Hydraulic un-coiler

● Supporting 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

c. Press and pinch and feed device

● It is good for improve the plates' surface and do straightening 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

● hydraulic telescopic shovel and hydraulic press and hit the head device etc. to feed the plate

● Drive model: all the rollers and gear box drives by 30 KW motor

d. Hydraulic head-cutting machine

● Adopt two columns structures, a press device, can cut the 4mmX1600 steel plates

● The up and down blades which are alloy material 6CrW2Si can adjust their gap

● The machine is used for the steel shear and to make the plate easy to slitting machine

e. Looper I

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

● The looper will create a buffer zone for easier into next stage process

f. Guide device

● On both sides of the mixer used vertical roller wheel device, lead the steel strip right into slitting host

● Pieces on both sides of guide bit screw adjustment on both ends of the vertical roll by, the width of the range: 500-1300mm

● Set the two roller material damping device, improve the accuracy of slitting

g. Slitting machine

● Power part: This is composed of power-stand, decelerator, 55KW 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(φ220mm, 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 20 blades with the machine

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

h. Scrap winder

● It consists of base, the shaft and plate of scrap material, friction wheel, supporting wheel chain, chain, decelerator and 7.5Kw electric machine

i. 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

j. 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

k. 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 110KW with controller to ensure the recoiling

l. Hydraulic exit coil car

● This car carries the finished coils and movable lift

m. Pneumatic system

● The pneumatic system is composed of the air power (prepared by the buyer), air source treatment components , salennoid , relevant pipeline and air cylinder, etc. The components such as salennoids are adopted high quality product

● Technical parameters: stress of air source: 0.4-0.6Mpa. The capacity: 1m³ /min

n. Hydraulic system

● hydraulic stand and pipe etc.

● Ensure the using of every hydraulic parts

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

o. 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
