Coil Cut To Length Machine CTL Machine 1600x4mm Cutting Machine

This is a coil-cut-to-length machine, we made for a Saudi Arabian client. It is available for coil widths 500mm to 1600mm, and thicknesses 0.5mm to 4mm. The main features of the cutting machine are as follows:

The whole coil cut to length line is easy to operate, controlled by one electric cabinet.
As per the client’s request, there is no pit along the whole production line.
The leveling machine is a 4-Hi leveling machine.
The metal coil cut to length line, working speed 10-20m/min.

Metal Coil Cut To Length Machine main component and introduction

Hydraulic decoiler with a coil cart

The core spindle with 4 PCS supporting arms makes the coil is close to a circle

When expanding, ensure not to scratch the coil painting.

Driven by a frequency conversion motor, and can be rewound.
A pneumatic disc brake is installed at the end of the spindle, which can generate unwinding tension and braking.
The pressing arm is installed above the spindle. The pressing arm rollers are coated with rubber. The electric rotation and hydraulic swing are used
uncoiler-driven motor power: 5.5kw
Uncoiler frequency conversion motor power: 7.5kw

2. Press and pinch device, leveling machine

Press and pinch function: Press the coil sheet, guiding and feeding it into the leveler
Hydraulic cylinder of press and pinch: diameter 80mm, stroke 400mm, 1 set, Diameter 63mm, stroke 600mm, 5 sets
Leveling rollers: up 7 rollers + down 8 rollers, total 15 leveling rollers
Leveling roller diameter: ф100mm
Leveling roller width: 1300mm
Leveling rollers material: 40Cr, quenched, with hard chromed.
Pinch rollers: 1 group, total 2 rollers
Supporting rollers: 2 groups, total 4 rollers
Supporting rollers diameter: ф90mm
Supporting rollers material:40Cr, quenched
Upper and lower support rollers use oblique iron regulation, and avoid leveling rollers when forced.
The machine’s basic frame is divided into upper and lower parts, connected by four strong tie rods. The upper stand is used to install the upper row leveling roller set. The lower stand is used to install the lower levelling rollers set and to support the whole body.
Driven system combined with motor, hard tooth surface reducer, gearbox transmission.

3. Hydraulic Cutter

Cutting motion: From up to down, the main machine automatically stops and then cuts.

Hydraulic cylinder diameter 100mm, 2 sets

After the cutting, the main machine will automatically start.

Material of blade: CR12MoV, cut from up to down, 4 sides to use

Length measuring: Automatic length measuring

Tolerance of length: +/-1mm

Cutting width:1600mm

4. Transport table

Conveyor belt: with a high tensile fiber conveyor belt, anti-skid, and wear-resistant.
Power: With the speed of the production line, it is driven by a 2.2kW speed-regulating motor with a reducer.
Mechanical structure: steel plate and square pipe welded assembly.
Length: 3500mm
Width: 1300mm
Function overview: Transfer the cut sheet material to the receiving device. Because the length of the shearing sheet is different, the speed of the conveying table can be adjusted according to the time shearing situation.

5. Automatic stacker

Width:1000-1250mm
Length:1000-4000mm
The cylinders push tidily and together automatically.

6.Pneumatic system

The pneumatic system is composed of air source (user provided), air source processing components, solenoid valves and corresponding pipelines, cylinders and so on. Solenoid valve and other components using high quality products.
Technical specifications: Air pressure: 0.5-0.8Mpa, gas supply: 1 cubic meter/min (compressed state)

7. Hydraulic system

The hydraulic system uses an integrated pump station.
Oil pump and valve use Beijing Huade products.
Other accessories choose foreign high quality products.

8. Electric system

Driven: Frequency conversion controller drives the uncoiling motor and levelling motor.
PLC system control.
It has a set length, shear numeration, speed adjustment, fault diagnosis, status display, and system protection function.
