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.
