High Speed Steel Sheet Cut To Length Line Light Gauge
Aluminum sheets in coils usually is softer in body and smooth in
surface, can be pure aluminum or aluminum alloy. most frequently
1xxx, 3xxx, 5xxx, 7xxx series aluminum sheets. Yield strength
≥65Mpa, tensile strength 170-305Mpa Coil sheets can be full soft(O
state), semi hard(H24), full hard(H18).
Aluminum coil sheet specification
aluminum coil sheet | thickness | width | weight | density |
0.2-6mm | 200-2000mm | 5-6T | 2.71g/m3 |
Aluminium sheet properties:
category | purity | grade | usage |
1xxx series | Al 99% | 1050, 1060,1100 | common |
2xxx | Cu (3-5%) | 2A16(LY16), 2A06(LY6) | aviation |
3xxx | Mn (1.0-1.5%) | 3003,3004,3005,3A02, 3A21 | common |
5xxx | Mg(3-5%) | 5052.5005.5083.6754. 5A05 | common, aviation |
7xxx | Zn | 7075 | aviation materials |
Characters:
According to the aluminum coil sheet characters, the cut to length
line must be fly cutting type
- non stop continuously flatten aluminum sheet without roll mark
- servo pinch feeding will hurt sheet surface, fly cutting doesn't
need that
- stacking system receives sheet piece by piece without hurting it.
- 6 hi leveling machine suitable for leveling soft aluminum sheets in
high precision
- automatic cantilever uncoiler is efficient and precise.
Composition
- 1.Coil storing saddle, store one or two aluminum coils
- 2.Coil loading car. take a coil from saddle and load a coil to
uncoiler
- 3.Single mandrel uncoiler: hydraulic expansion mandrel for standard
Ф508mm, hydraulic centralize adjusting, with paper peeler.
- 4.Coil head snubber roller, peeler shoveling plate: to open coill
head from uncoiler and send into pinch feeder
- 5.2+17 Roller Leveler: 6Hi, 2layers work rollers, 2layers
middle rollers and 2layers backup rollers, back tension is
beneficial between leveler and uncoiler.
- 6.Pit Accumulator or transmission roll table: pit accumulate sheet
in pit to ensure leveler continuous working, transmission roll
table is also workable in synchronous fly shearing.
- 7. Pairs of double rollers, with servo Length Measure (and Film
Laminating): Servo length measuring(pair of pinch rollers or 2+5+2
rollers structure driven by servo motor and controller), with PU
coated pinch rollers for film laminating
- 8.Fly shear, with screw rod guide: cutting frequency is relative to
sheet length, hydraulic cutting from down to up.
- 9.Belt Conveyor: convey finished sheets to stacker
- 10.Stacker: receiving sheet piece by piece and piling up on lifting
table, stacking load 5T.
- 11.Sheets Car, output roll table: deliver sheets out, then packing.
can be two cars, one working and the other waiting.
- 12.Hydraulic system: 11KW gear pump provides 12Mpa pressure.
- 13.Electric Control System: One electric cabinet and two operator
panels(one console for servo measuring, PLC, HMI and stacking, one
for uncoiling and leveling) with complete and safe functions
