Medium Gauge Slitting Line

Automatic Stainless Steel Slitting Machine

▷Medium Gauge Slitting Machine – Coil Slitting ◁. Cutting is a shearing process in which the sheet metal is cut by two opposing circular blades, like a can opener. Slitting can be performed in a straight line or on a curved path. The circular sheet metal cutters can be driven, or the work may be pulled through idle cutters. Slitting usually produces a burr that must remove.

Medium Gauge Steel Coil Slitting Line

A metal cutting machine design to cut longitudinally the wide steel coils into different narrow steel strips for continuously producing cold-formed sectional steel products. Basically, there are two types: high-speed and normal-speed slitting machine lines. A high-speed slitter can work at a max speed of over 150 m/minute and over 10 strips can be produced; while a normal-speed slitting machine can work at most 40m/min with less than 10 strips slit.

Brief Introduction Steel Coil Slitting

A steel coil slitting line is used for slitting the carbon steel coils and hot dip galvanized coils to prepare for the next process.

2) Hydraulic Entry Coil Car Automatic Coil Slitting Machine

The car can move levelly and vertically, which is convenient for putting the steel coils into the de-coiler.

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

3) Hydraulic Decoiler Steel Coil Slitting Line

• 4KW motor drives the decoiler running and the hydraulic drives it expands and shrinks.

• It designs with a supporting stand that is driven by hydraulics to ensure the heavyweight coils can be loaded.
• design with the press arm, the roller is made by rubber,and this design is used to prevent the coils from losing.

4) Hydraulic Press and Pinch Device High-Speed Slitting Machine

• It is good for improving the plates’ surface and straightening then guiding the steel plates into the next process.
• made by drive device, 2 pinch rollers, and frame.
• The gap between rollers can be adjusted manually to make sure the leveling quality.
• Drive model: all the rollers and gearbox drives by 30 KW motor

5) Hydraulic Cutter Steel Strips Slitting Machine

• Adopt two columns structures, a press device, can cut the 1.5mmX1250 steel plates ;
• The up and down blades which are alloy material 9CrSi can adjust their gap.
• The machine use for the steel shear and to make the plate easy to slitting machine.

6) Looper Steel Slitting Line Machine

• pit equip with 2 groups of magic eyes to control the speed buffer between decoiler and slitter.
• the magic eye is controlled by PLC.
• pit size: 4500 mm x 1750 mm x 4000 mm.

Function: it uses to eliminate the different speeds and make the plates which are in the wrong rail back the right way. At first, the hydraulic cylinder lifts 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 photo electricity devices to adjust the high or low speed to make sure the certain store quantity in the pit.

7) Side Guide Device Steel Coil Slitting Line

• It uses vertical rollers on 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.

Function: it uses to prevent the sheet from running in the wrong way. On both sides of the plates width way, the stand rolling is fixed on their own position and can adjust the width manually to match the different width plates. There are 4 rollers (quenching HRC 55-58) which divided into 2 rollers on each side.

8) Slitter (55 KW DC ) Coil Slitting Line

• Knife pivot specification: φ200 x 1350 mm, material: 40 Cr, heat treatment HB 225-250.
• Host machine: This is composed of the bottom stand, fixed bracket, big slide, knife pivot(φ200 mm, 2 pcs), movable bracket, slide, the front and back adjustable device of the bracket, knife pivot lifting, and pressing down adjustment device.
• Power part: 55KW DC motor with JZQ 650 decelerator and universal coupling as well as gear distributing case, coupler, spindle, connecting cover, etc.
• The knife pivot press-down device adopts the motor to lift up and down.
• It changes the blades by moving out the bracket hydraulically and is very convenient and fast.

9) Scrap Winder (4 KW ) Metal Slitting Machine 

It consists of a base, the shaft, and plate for scrap material,and friction wheel, supporting wheel chain, and chain, and decelerator 4 Kw motor, etc.

10) Looper Sheet Metal Slitter 

• The roller table lifts up and down by hydraulic. All the rollers on the table are chromed and between the rollers, it is designed with the Bakelite plate (Function: can prevent the sheets from scratching)
• At the exit part of the roller table, it is designed with the pre-dividing device.
• The size of the pit: 3500 mm(L)x 1750mm(W) x 6000mm(D)

11) Tension Stand Slitter Machine Steel

• It is composed of the base, and pre_dividing device, tension press device, and so on. It use to divide the strips and adjust the tension power for rewinding to ensure rewinding quality.
• design with two dividing devices and a press device. One hydraulic block device and two roller devices.
• press rollers, as well as the two-roller device at the exit part, are equipped with an air cylinder to control the lifting.
• The dividing shafts adopt the linear slider design which is convenient to change the slitting requirements according to cutting demand.

Why use a steel slitting line?

Once we need steel raw material in different widths for different profile forming usage. we need to shear the steel coil in various widths because in the market available coils are in a wide range such as 1000mm and 1250mm and 1200mm, 1500 mm, and so on. So for different industry usage, we need to slit coil too small width with a slitting line.

Automatic high-speed slitting lines are the most convenient slitting lines to work with, the complete slitting line starts with a hydraulic coil car and de-coiler, then the steel coil opens continuously and storage in a hook after leveling and shearing parts Then reaches the main part of the slitting line SLITTER, includes blades and shim to slits steel coils, then again storage loop to storage steel strips after slitter, From here slitting line start to prepare recoil steel strips, after loop it passes tension pad and pinch roll, and go to hydraulic powerful Recoiler. Recoiler is a really important part of slitting line, for recoil steel strips in high tension and poling power.
