2.1 Decoiler 1 set (includes coil car)
This deociler is single head model, motor drives decoiler shaft to open steel coil and hydraulic power make decoiler shaft expanding device to make steel coil to be fixed well on decoiler shaft. when complete line is on common working condition, decoiler is working automatically. In order to make decoiler operator to be safe, decoiler also includes pneumatic brake and press arm. It will protect opeator among working process.
Decoiler matches with one coil car, it is used to loading and unloading steel coil from decoiler shaft. coil car can move forwardly and back, motor drives car to move; coil car support table can lift up and down, hydraulic cylinder supplies power for this device.
Suitable steel coil outer diameter: 1820mm
Suitable weight of decoiler and coil car: max 10000kg
Suitable steel coil width: max 750mm
Motor power of decoiler: ≈15Kw
Motor power of coil car: ≈5.5Kw
2.2 Leveler machine 1 set
This leveler uses 7 rollers model. Up layer has 3 pieces rollers, and down layer has 4 pieces rollers. the rollers' space which is between up and down layer can be adjusted manually by screw mandrel.
Two pairs guide rollers are installed in the front of leveler roller part, feed roller is pinched well by pneumatic cylinder. Pinch roller working speed can be adjusted by transducer, operator can control it according to actual working requirement.
In the front of main leveler part, one special Telescopic shovel head is installed on leveler base plate. When raw material will get into leveler part, this shovel will move up and guide raw material to get into leveler device smoothly.
Max working speed: 20m/min
Suitable steel coil width: max 750mm
Suitable steel coil thickness: max 3.0mm
Motor power: ≈11Kw

2.3 Material loop 2 sets
Material loop is used to make working speed to be matched for different necessary parts. Complete line totally includes 2 sets loop. One loop is between leveler and puncher, the last one is between puncher and main roll former.
Within the loop channel, it includes few photoelectric switches. These switches are used to control raw material feeding location in each loop channel.
3.4 Servo feeding device 1 set
This device is installed in the front of multi-station puncher. It is fixed on puncher base plate.
This servo feeding device is driven by servo motor, operator can set few group working data oncontrol system, and then servo feeding device will feed raw material sheet one time by one times.
Feeding device also has one pair feeding rollers, it is lift up and down by pneumatic cylinder.
Max feeding speed: 40m/min
Each time feeding length tolerance: ≤±0.15mm
Servo motor brand: Japanese Yaskawa
Servo motor power: 5.5Kw
Feeding roller material: 9Cr2Mo or GCr15 (HRC55~60)
3.5 Multi-station puncher 1 set
This kind of puncher is multi-station model, it includes few working units, these working units are used to finished different holes' punching action.
Main components of puncher are base plate, punch die, punch frame, adjustable device for each punch die unit, etc.
According to our facotry experience, common speed way guardrail needs to use 8 working units to finished necessary hole. Unitl now, final client does not show final punch hole drawings, so puncher working units cannot be confirmed now. when order is confirmed, both parts need to sign on punch hole drawing together.
Puncher will matches with one complete set punch die, these die will satisfy different hole requirements.

3.6 Main roll former 1 set
Main roll former is single forming stand model (torii model), motor, decelerator, chain and gear drives roll former to form profile section.
Each forming stand has power, the down forming shaft part is power part. some important forming stands are matched with in-phase gear, main aim is to make formign process to be precise.
All roll forming rollers are finished machining and polishing for roller surface. Roller material is Cr12 (HRC58~62), the physical character is similar as American D2 material.
Raw material of forming stand: QT470
Raw material of forming shaft: 40Cr
Raw material of forming roller: Cr12
The diameter of forming shaft: φ90mm
Motor power of main roll former: ≈55Kw
Main roll former working speed: 10~15m/min
Complete line actual working speed: 5~6m/min

3.7 Moving cutter 1 set
This cutter working action is continuous model, when cutter action is doing, complete line needs not to be stopped.
Main componets of cutter are base plate, pneumatic cylinder, linear guide rail, cutter frame, cutter die and hydarulic cylinder, etc. hydraulic cylidner supplies power for cutter, cutter moving power is supplied by pneumatic cylinder.
Cutter die material: Cr12MoV (HRC58~62)
Cutter working speed: 5~6m/min
When cutter cuts the final profile, these is no waste piece.

3.8 Hydraulic system 2 sets
These two systems are used to supply power for hydraulic decoiler, coil car, multi-station puncher and moving cutter.
A pump and accumulator composite structure, punching and cutting action speed is much fast, it can improve production line working speed. Cooler with air-cooled, high production requirements to meet the work load and high temperatures. The hydraulic system which is specially design for the high speed puncher and moving cutter is much professional.
Main components of system inlcudes motor, oil pump, filter, oil tank, electromagnetic valve and etc.
Hydraulic oil of this kind of system should be kept on grade 6~8.
3.9 Electricial control system 1 set
This system uses Mitsubishi (or same level brand products) PLC to control all working actions. Production quantity and each piece length will be automatically measured; human and machine interface, touch screen is input and cancelled the working data. It is convenient to control the roll forming machine.
The control panel has English operation interface, it is convenient to operator to input and cancel working date.
Main componets of electrical system:
PLC: SIEMES (German brand products)
Transducer: Delta (China Taiwan brand products)
Touch screen: WEINVIEW (China Taiwan brand products)
Low-voltage apparatus: Schneider (French brand products)
