 Technical presentation on Straightener feeder and decoiler 3 in 1 machine
(NCHW-1000B)



 

The buyer’s main parameters:

① Material type: Aluminum, low carbon steel

② Thickness: Aluminum0.03-0.125inch(0.762-3.175mm)

                Low carbon steel: 0.015-0.06inch(0.381-1.524mm)

③ Coil weight: 6000ib(2722kg)

④ Feeding length: 6-20inch(152.4-508mm)

On the basis of the above data, the seller suggested the following feeding machine:

 

NCHW1-1000B model decoiler straightener feeder 3 in 1 machine

The machine was made up of decoiler, automatic loading car(OPTIONAL PART), straightener and feeder machine

Equipment capacity:

a)      Straightening material: Aluminum, carbon steel, stainless steel and some other kinds of metal coil

b)      Straightening thickness: 0.3mm3.2mm

c)      Straightening width: 70mm1000mm

d)      Coil width range: 70mm1000mm

e)      Coil ID:450mmΦ530mm

f)       Coil OD:Φ1400mm

g)      Max. coil weight: 5 tons

h)      Feeding precision: 0-500mm, ±0.10mm/m (mould with pin can reach ±0.05mm); above 500-1000mm, ±0.20mm/m.

i)       Straightening speed:22m/min

j)       Straightening tolerance: 1.5mm/m²

k)       Yield strength≤245MPa

l)       Total power:≌18KW (including the machine head servo driver, machine head lift motor, decoiler driven motor, hydraulic station motor)

m)     Machine working direction: Face to console, left to right (can be customized)

n)      Machine color: beige, warning and moving section is blue (can be customized)

1.1 decoiler:

a)      Coil loading type: Single head with cantilever

b)      Max. loading capacity: 5000kg

c)      Expansion type: Hydraulic

d)      Brake type: pneumatic, stable and safe, also can prolong lifetime of the power system

e)      Mandrel hydraulic expansion system. The hydraulic station provide power to drive the hydraulic cylinder to expand & draw back the mandrel to clamp coil or release the coil.

f)       Press arm device to hold the strips, preventing coil loose. Further more, the press arm equipped with a PU roller to hold the strips, don’t scratching strip surface.

g)      Support arm device. Driven by hydraulic-cylinder, it was use to guide and support strips, Further more, several sets of rollers installed in the device, and all rollers were chrome plated, the surface is very smooth, preventing scratching material surface.

h)      Limit arm device, clamping coil in width direction, preventing coil collapsing when coil were too narrow. Further more, the width between two back gauge arms were designed adjustable by operate the manual wheels, coil width range is 70mm-1000mm.

i)       Machine equipped with hydraulic station, providing oil pressure to drive the mandrel expansion & contraction and hydraulic cylinder.

j)       Sensor device: electric eye loop control system, stable, safe and long lifetime. With the electric eye loop control system, the decoiler release strips automatically.(you can refer to the following image)

1.2          Automatic loading car

The machine was used to load coils and automatically lift the coil to the mandrel of the decoiler machine. And then the mandrel can expand and clamp the coil.

a)      Loading capacity                                5T

b)     Up-and-down movement power source             Hydraulic

c)      Horizontal movement power source                hydraulic motor

d)     Coil collapsing preventing fixing device             4set

 

1.3 Straightener-Feeder

a)      Structure: Servo motor driven, synchronous belt transmission, gear transmission

b)     Servo motor and driver: Siemens AC380V 7KW

c)      Straightening roller: 9 (upper 5/down 4)

d)     straightening roller diameter:φ60mm

e)     Pinch roller: 2pcs

f)      Feeding roller: 2pcs
All the roller material is GCr15, after quenched, high frequency annealing, the hardness is HRC58°-60°and then precision polishing.

g)     Gear: Material adopted 40Cr. The center quenched, teeth high frequency annealing and precision polishing.

h)     Straightening adjustment: worm screw adjustment, dial indicator display

i)       The entrance clamping roller: 2pcs

j)       Release type: pneumatic

k)      Feeding control: get signal from press encode or cam box, and controlled by PLC, HMI is touch screen.

l)       Material input guide roller: 1group (manual adjustment)

m)    Lubrication type: lubrication grease, manual grease bump lubrication

n)     Threading table device. It equipped with chrome-plated rollers and guided strips to go through the straightening part.

o)     Coil tip flatness device. It was mainly to press and flat coil head and end of the coil. Usually, the coil head is curvy, if without this device, the material is hard to go through the straightening part. But with this device, when the strips comes then entrance of the straightening part, the tip flatness device and press and flat the coil head and go through straightening device smoothly.

p)     Straightening manual adjustment wheel. The operator crank the manual handle to adjust the accuracy of the straightening part.

q)     Outgoing catenary to assistant support material device. It was mainly used to guide strips from straightening part to press machine.

r)      Manual control box. It was mainly used when coil run out and need to change a new coil and let the strips go though the straightening part at manual model.

s)      HMI. The operator operate the machine and set data in this device.

t)       Worm gear screw jacks device. It main used to adjust the pass line height. It was lifted the straightening part by a 0.75kw motor, easy to operate.

u)     Stop stock wheel manual adjust device. Crank the handle, the operator can adjust the distance between two stop stock wheels easily.
