Aluminum Sheet Rotary Shear Fly Cut To Length Line (3 x 1800)
Aluminum Sheet is light in mass density, bright smooth surface, softer body, aluminum coil can be very wide, very big dimensions, made from hot rolling and then cold rolling process. Aluminum coil sheet cut to length line should be fly cutting, rotary shear is efficient fly cut to length solution.
Characters:
- non stop continuously flatten aluminum sheet without roll mark
- servo pinch feeding with encoding to know sheet length, fly cutting match with the length
- Double rotary shear actions ensure the cutting location precisely.
- stacking system receives sheet piece by piece without hurting sheets.
- 6 hi leveling machine suitable for leveling soft aluminum sheets in high precision
- automatic cantilever uncoiler is efficient and precise, mandrel segments are teeth pinion edges overlapping with each other.
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 |
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.Rotary shear: cutting frequency and location as per sheet length and speed.
- 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
