Name: curved corrugation automatic production line
picture 1 section of profile
proposal of production line
This production line realizes decoiling, roll-forming, punching, curving, cutting and stacking as an automatic producing process, requiring 1 worker.
Transmission of roll-former is chain wall plate
Curving is after roll-forming, then cutting. The curving machine can curve two-direction, the curving radius is adjusted manually.
The puncher has three punching station, it punches all holes one time together (we call this bulk puncher)
total power of this production line：
main roll-former: 15KW
curving system: 2.5KW
hydraulic system: 11KW (including the motor power)
The dimension is 12m*1.5m*1.3m
decoil→guide&feed→level→roll-form→ bulk punch→curve following roll-forming→hydraulic cut→stack
basic parameters of finished product
Thickness of panel: 0.5-3.0mm hot-dip zinc-coated steel
Mechanical performance：yield strength 340MPa
tensile strength 470MPa
coil width： 1000mm-1200mm or as per customer request.
inner diameter of coil：φ460-550mm
The standard length of finished products: pls see the above drawing.
main configuration and technical proposal
（pls refer picture 6）
passive decoiler 10T
/During normal processing, the decoiler works passively.
The capacity of this decoiler is around 10T, the width of coil is 1250mm.
Feed&level system: five-roller leveler.
（Pictures are based on specific profiles）
The construction of roll-former: wall frame
Transmission way: motor-chain drive-chain -main shaft
as per drawing
Roll-forming station: 17 stations
15KW 415V 50HZ 3-相 交流电机（刹车电机 ABB）Brake Motor Model：ABB
Main power: 55KW 380V 50HZ 3-phase brake motor
Main reducer: Cycloidal Pinwheel Reduction Box: 33-43-15KW.
Material of rollers: GCr15 high-carbon chromium bearing steel, the hardness after heat treatment: HRC58-62
The shape of rollers is designed through German design software COPRA, and processed on the precision NC machine. The surface of rollers is polished
The diameter of shaft for rollers: φ120mm, 45# steel quenched and tempered.
The dimension of roll-former: around 12m(length)*1.5m(width)*1.3m(height)
The hydraulic puncher consists of gantry(gantry consists of upper and down board, and post), punching die, hydraulic oil cylinder and etc.
This puncher has three station, punches all holes together one time, each station has two oil cylinder, middle punch die has rack-and-pinion synchronizer
Demould way is combining polyurethane soft demould and hard press die together.
In order to install and exchange punching die easily, here we use construction in ball-lock style.（Modified and bases on the specific drawings）

The construction is three-roller and horizontal type
This curving machine curves continuously following the roll-former, this can avoid the straight ends of panel, and besides, panel can be feed in and curved manually.
the minimum radius of curving arch is R2m, the radius can be adjusted.（Based on the specific drawings.）
hydraulic cutter for corrugation panel
This cutter consists of shear, angel adjustment system, system for adjusting higher or lower and backward or forward.
Cutting power: is provided by hydraulic oil cylinder.
Blades: the shape is matched with corrugation panel, the blade material is Cr12 die steel, hardness after quenched: HRC58-62.

stacker for finished products
Stacker consists of elevator device, device to move main carriage crosswise&longitudinal, stacking carriage, transmission device and etc.
The stacker can be moved crosswise manually, in order to stack at two station
Usual run-out and stack process will not interfere swinging finished products
When the height of stacked finished products has reached 200-300mm, the stacked products will be move aside to be packed and swinged, another station will continue stacking.
hydraulic system for puncher：
main power: 55KW, 380V 50HZ 3-Phase
power of cooling pump: 4KW，
system pressure: 25MPa,
output volume of oil pump：63ML/R。
hydraulic system for decoiler：
main power : 7.5KW, 380V 50HZ 3-Phase
system pressure: 16MPa,
output volume of oil pump：20ML/R.
computer control system
ABB frequency convertor
touch screen (HMI)(Modified)
Rotation encoder Omron brand±0.1mm positioning fiber
Main electric control elements is of brand Schneide and etc.
Two operation way: manually and automatically
safety and protect function：
During the manual or adjusting work way, the switch of operate board can give order to each part.
During the automatic work way, the switch of the operate board can not give order to any parts, only the emergency stop switch is valid.
Emergency stop buttons are set onto the both ends of production line, in order to emergently stop the machine when error happened, to insure the emergency brake of the system.
There is drive inverse function in a short distance.
technical parameter of corrugation panel
Tolerance of total length：±1mm
Tolerance of rib depth：± 0.8mm
Tolerance of hole location：≤0.3mm
The arch of corrugation panel: can be adjusted, the minimum radius is 1.6m
Tolerance of arch of corrugation panel: ±5mm adjustable
The quality of corrugation panel appearance: the zinc surface should be kept well basically, during production, some zinc will stick onto the rollers, so workers should often clear the surface of rollers, to insure that there’s no obvious scratch on the roller surface.
Production speed: 1 piece of finished product per minute
