TECHNICAL PARAMETERS
I. Specifications
1) Profile width: 3"/3.5"/3.625"/4"/5.5"/6"
2) Profile flange: 1 5/8"
3) Profile thickness: 22 gauge to 16 gauge
4) Material : galvanized coil sheets: ASTM A1003 & ASTM A653
5) Max yield: 80ksi at 1.6 mm (16ga) material thickness.
The range of web size is 3" to 6" (75-160mm). It is divided into 4 areas: 3"-3 5/8", 3 5/8"-4"mm, 4"- 5.5"mm, 5.5"-6". Each of the 4 areas will have related chamfer cut tooling and notch cut tooling. So this machine can be easily exchange punch tools when produce difference size of steel profile.

V. Technology Parameters
The weight of the Machine: About 10 Ton
The total dimension with un-coiler, Out-let Table is:
(length) 16m x (width) 1.71m x (height) 2m.
The dimension of forming parts: (length) 8m x (width) 1.71m x (height) 2m.
1)Hydraulic de-coiler (The hydraulic de-coiler is excluded in this quote)
- De-coiler Type: Hydraulic auto de-coiler
- Weight capacity: Max 5.0T
- Diameter of inner: 480-510mm
- Diameter of outer: 800mm
- Motor power: 3.0Kw,60Hz, 380V(Customized)
- Control type: Electric button control
- Function: Auto rotation feed sheets into roll forming parts. Semi auto for loosening and tightening coil
- Weight of de-coiler: 1000KGS.
- Side Locks provided on de-coiler to fix coil.
2) Punching
All punching dies are made from Cr12. Driven by hydraulic station. Holes parameter are able to set by PLC, Including Punching length and numbers.
Four leveling devices is used to fasten the raw material. When punching system is on working, the raw material will be fixed tightly by leveling device to ensure the job precision.
- Hydraulic station: 11 kw + fan cooling system
- Driven by servo motor.
- Hole Type:
a. Right flange punching
b. Left flange punching
c. Web triple hole
d. Bolt hole
e. Online-swage
f. Truss cut
h. Web notch
i. Dimple
j. Service hole
k. Lip cut
Pre-punching holes: 1,2,3,4,6,7,9,10
Post-punching holes: 5,6,7,8
1. Punching precision within +/-1mm
2. After hole punching, raw material will be driven into roll forming system.
3) Rolling Forming System
- Main motor type: 3 phases
- Main motor power: 15Kw, 60Hz, 380V (suits Australian power requirements)
- Servo motor brand: INNOVANCE
- Speed of forming: 25m/min
- Comprehensive speed: 5-12m/min
- Roller: 17 groups rollers. Roller Material is Cr12 mould steel being quenched treatment, with digital-controlled procession. This ensure rollers are all on good condition and long life.
- Shaft & Frame: Shafts of rollers are tooled by grinding machine for two times to ensure the precision of final product.
4) Changing Size
- Full-automatic (change sizes by PC control system)
- Machine is designed to change profile size within 1 minutes. This type of system is easy to operate. Only need to set the profile specs on the control panel, the roller stands will move in and out automatically.
- Size range: Web: 3" -6"
- Flange: 1 5/8"
- Lip: 5/16" - 3/5"
- Motor power: 0.75kw, 380v, 60Hz, totally 2 sets.
5) Hydraulic Cutter
- Cutting material: Cr12 Cr12MoV Cr12(total three blades)
- Hydraulic motor power: 11KW
- Hydraulic Pressure: 16Mpa
6) Out-let Table
4 meter material receiving table, with a stacking platform.
To consider easy for shipment. The components of Out-let Table will be well packaged and will be installed at Buyer's warehouse.
7) Safety Guard: Safety Guard covers the whole machine to ensure worker's safe.
Each parts of safety guard is linked with lock. Safety switch is available to stop machine when safety guard is open.
8) PC control system LG-R1.
- The control system has capacity to program production CNC by inputing Dahe's TXT to CSV format and connect with machine directly. It can control machine auto-running and running status dynamically, including punching, cutting and size changing.
- Manual length/punching program of production
- The computer can control production line including leveling, punching, cutting, conveyer table and roll forming station. Speed of the machine can be adjusted.
- The choice production data can be showed on screen.
