line technical specification of each part

(1)hydraulic decoiler with decoiler car:

this decoiler is assistant support model, it includes a decoiler car.

motor power drives decoiler shaft opens steel coil, and hydraulic power expands steel coil inner diameter.

the decoiler is assistant support model, max loading capacity: 10000kg

suitable steel coil inner-diameter: ￠508mm/￠610mm,

max outer diameter: ￠1200mm

decoiler shaft expanding range: 50mm (￠465mm~￠515mm)

when the line is working, the decoiler is moving following the complete line working actions. also the decoiler includes brake device, when the line has urgent trouble, the decoiler can be stop in time.

the decoiler car is driven by motor, and max loading capacity is 10 tons.

decoiler car move speed is 3m/min, and it can move forwardly and back on horizontal guide rail.

note: when the decoiler and decoiler are installed well, the decoiler car is under ground. (please see reference lay-out drawing at the second page.)

decoiler and decoiler car outer former reference:

(2)material guide device:

the device includes press arm and material guide table. press arm has power roller to press well the raw material; and material guide table will support the coil head and end part when those parts are sent leveler machine.

press arm and material guide table are all driven by hydraulic power.

(3) leveler machine:

main parameters of leveler machine:

pinch roller number: 1 pair

leveler roller number: 11 pieces

leveler roller material: 60crmov

main roll former working speed: about 20~25m/min

main motor power: about 22kw

about the leveler structure, 5 leveler rollers are on up layer, and 6 leveler rollers are on down layer; up and down layer leveler roller are all have 3 lists support roller.

the leveler roller space can be adjusted, and leveler obliquity can be adjusted.

the leveler driver system includes motor, decelerator, wheel box and coupling, etc.

suitable power voltage: 380v/50hz, 3 phase

machine outer form reference:

(4) straighter device:

2 groups’ vertical straighter rollers are located in the front and back of the leveler

all rollers are installed on separated slider, and use manual power to adjust slider on forward and back direction. in order to satisfy different width material requirements.

(5)hydraulic cutter:

non-load continuously working action number: ≤20 times

cut degree: 1.5°

hydraulic power drives the cutter, when the cutter blade is moving on cutter frame, one twist spindle will force the hydraulic cylinder to be in-phase by 2 pairs gear rack.

cutter blade space can be adjusted by working flat.

on the entrance of the cutter, the support table has support roller, and the exit part of the cutter also has support roller, and those rollers will move following the cutter frame working action.

machine outer form reference:

(6)plc control system:

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, the working data can be input and cancelled on control panel. it is convenient to control the complete line.

the control panel has english operation interface, it is convenient to operator to input and cancel working date.

all line has 3 working operation models; it is adjustable, manual and automatic. different working operations will satisfy different working action requirements.

main electric accessory products shown:

plc: mitsubishi (or same quality brand products)

transducer: delta (china taiwan)

coder: omron

(7) product rack (un-powered):

one part, total length is 3 meters. in order to collect the final product and final products is convenient to be stacked by workers.

this rack can be disassembled easily, in order to satisfy different working condition requirements.

note: the line will be matched some special tooling, wearing parts and wear parts drawings.
