Hydraulic entry coil car with V shaped table

It is used to load the coil, to prevent from damaging the car due to putting the coil into car directly.

It is one pair (two pieces), length 1000mm, width 480mm.

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 4 guide pillars

The level movement is driven by cycloid motor

Capacity:20T(Max)

Function:  It is used to lift up and down, move forward and back to make it easy to load the coils on decoiler. Hydraulic controls lifting, motor drives moving. The car is controlled on the auxiliary control panel. Its moving speed is 6-7m/min. When the coils on decoiler, the car will return back to the start position. It can also carry back the unfinished coils from decoiler.

Hydraulic double head decoiler  

Supporting steel rolls and uncoiling

It is designed with the double hydraulic movable structure

The hydraulic cylinders on both sides drive the landscape orientation movement

It is equipped with the brake devices and 3-step taper decoiler and the brake wheel.

Mechanical structure: the process is welded by steel plate and steel.

The capacity of it can reach to 20Tons

Hydraulic Press and pinch device（37KW AC）

It is good for improving the plates’ surface and do straightening then guiding the steel plates into next process.

It is made by drive device , 2 pinch roller and 5 leveler rollers and frame.

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

Shovel head is with 4KW motor drive the coils running and do the decoiling with tension.

Drive model: all the rollers and gear box drives by 37 KW motor

Looper

The pit is equipped with magic eyes to control the speed buffer between decoiler and slitter

Magic eye is controlled by PLC.

The pit size: 4500mmX2200mmX4000mm.

Function : it is used to eliminate the different speed and make the plates which in wrong rail to back the right way. At first, the hydraulic cylinder lift the bridges to pass the steel sheets. when working , the bridges will lift down , the steel will be stored in the pit. There is equipped with the photoelectricity devices to adjust the high or low speed to make sure the certain store quantity in pit.

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 500-2000mm.

Function : it is used to prevent the sheet running to the wrong way. On both sides of the plates width way , the stand rolling are fixed on their own position and can adjust the width manually to match the different width plates. There are 4 rollers (quenching HRC55-58) which divided into 2 rollers on each side.

Slitter (90KW DC )

Knife pivot specification: φ220x2000mm, material: 40Cr, heat treatment HB225-250.

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.

Power part: 90KW DC motor with decelerator and universal coupling as well as gear distributing case, coupler, spindle, connecting-cover, etc.

Knife pivot press down device adopts the motor to lift up and down.

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

Hydraulic Scrap winder (4KW )

It consists of base, the shaft roller and decelerator and two piece 4Kw motor ,etc.

Equipped with hydraulic system to make it more effective

Looper

The roller-table lift up and down by hydraulic.

At the exit part of the roller table, it is designed with the pre-dividing device.

The size of the pit: 4000mm(L)x2200mm(W)x6000mm(D)

Tension stand

It is composed of the base,pre-dividing device, tension press device and so on . It is used to divide the strips and adjust the tension power for rewinding to ensure the rewinding quality.

It is designed with two dividing device and press device. One hydraulic block device and two roller device.

Recoiler (132KW DC)

It adopts the hydraulic expand and shrink to tight the coils inner diameter, the inner diameter is 508mm.

Designed with 8-fan-shaped plates which can be a round circle and machining as a whole to ensure the recoiling quality. It is designed with clip mouth and clip the strips heads.

It is designed with the hydraulic press arm equipped with the spacers to guarantee the even rewinding quality.

It is equipped with the hydraulic pushing device to unload the coils

132KW DC motor can guarantee the rewinding quality.

Gear adopts casting ZG45，the surface of the gears is processed by quenching， HRC45°,

Diameter of Mandrel of recoiler：220 fan –shaped plated are 45#X60mm (thickness), quenching, HB: 220mm-250mm.

Press arm lift up and down by hydraulic and it is equipped with the pushing plate which is used to help pushing the coils to the coil car.

Hydraulic exit coil car

This car carries the slitted coils and movable lifting.

Hydraulic cylinder drives it lift up and down and is equipped with 4 guide pillars.
