Tank Aluminum Roll Form Machine Five - Roller Level System 460-550
mm Inner Dia
A. proposal of production line
1. This production line includes decoiler, roll-forming, punching,
curving, cutting and stacking as an automatic producing process,
requiring 1 worker.
2. Transmission of roll-former is chain wall plate.
3. Curving is after roll-forming, then cutting. The curving machine
can curve two-direction; the curving radius is adjusted manually.
4. The puncher is hydraulic punching, the computer control it
5. The curver can be part of the roll former and stand alone, if
stand alone, it will be have its own hydraulics and power source
and equipped with one set of flat collection table and curve
6. The curve can be tighter than 2m. The min value is 1.5m.
7. The lip rolled before the guillotine so the guillotine must be
able to cut the normal corrie profile and the corrie profile with
the lip and the same as the curve, to curve the normal corrie
profile and the corrie profile with the lip. (See the detail
8. Total power of this production line:
main roll-former: 15KW Brake Motor (refer to the final machine)
Curving System: 2.2KW (refer to the final machine)
hydraulic system: 7.5KW (including the cutting) (refer to the final machine).
9. The dimension is 12m(L)*1.5m(W)*1.3m (H), 1.3m height includes the cutting, if without
cutting, the machine height will be 1m or as per customer request.
B. Technical process/sketch
decoil→feed→guided→roll-form→ bottom punch→lip adjust→curve
→cutting→collection table (see the detail drawing)
C. Profile Drawing
Picture 1 section of profile
D. Basic parameters of finished product
1. Thickness of panel: 1mm zincalume sheeting G300.
2. Mechanical performance: yield strength 340MPa, tensile strength 470MPa.
3. coil width:900mm.
4. inner diameter of coil: φ460-550mm.
5. The width of finished profile width after formed: (As per
E. main configuration and technical proposal
(a) passive decoiler 10T
During normal processing, the decoiler works passively.
The capacity of this decoiler is around 10T, the width of coil is 900mm.
(b) Level system: Five-roller leveler.
1. The construction of roll-former: wall frame.
2. Transmission way: motor-chain drive-chain -main shaft
3. Roll-forming station: 18 stations
- Main power: 15KW 415V 50HZ 3-phase Brake Motor
- Main reducer: Cycloidal Pinwheel Reduction Box: 33-43-15KW.
- Material of rollers: qualified 45# steel, galvanization treatment,
to increase the smooth of roller surface and make sure of its
service time and also avoid surface damage of the sheet.
- 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: φ85, 45# steel quenched and tempered.
(d) hydraulic puncher
1. The hydraulic puncher consists of gantry (gantry consists of
upper and down board, and post), punching die, hydraulic oil
cylinder and etc.
2. This puncher design is punch die, the computer control it
optically, each station equipped with two hydro-cylinders, the
middle punch die installed with gear and rack.
3. Demould way is combining polyurethane soft demould and hard
press die together.
4. In order to install and exchange punching die easily, here we
use construction in ball-lock style.
(e) curving machine
1. The construction is three-roller and horizontal type.
2. 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.
3. the minimum radius of curving arch is R1.5m, the radius can be
adjusted.(Based on the specific drawings.)
4. Outside Lip (see the detail drawing)
(f) 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: HRC58-6
- ( g ) stacker for finished products
1. The stacker can be moved crosswise manually, in order to stack
at two stations
2. Usual run-out and stack process will not interfere swinging
3. 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.
1. /hydraulic system for puncher:
Main power: 7.5KW, 415V 50HZ 3-Phase
System pressure: 25MPa,
output volume of oil pump:63ML/R.
(i) computer control system
1. MITSUBISHI (PLC)
2. Panasonic/Mitsubishi Frequency convertor
3. Touch screen (HMI)
4. Rotation encoder Omron brand±0.1mm positioning fiber
5. Main electric control elements is of brand Schneide and etc.
6. Two operation way: manually and automatically
7. safety and protect function:
