Lamnia Bruk Cold drawing line 12/10.
COMPLETLY REFURBISHED and UPGRADED with new wirering, interface and PLC control!
Cold Drawing Line from Lamnia Bruk. Strong, high quality swedish cold drawing line.
The line has undergone extensive refurbishment, many new parts.
TECNICAL DESCRIPTION
- Wire direction: Left to right
- Power pull bloc 220 kW (ac motor)
- Power spooler 50 kW (ac motor)
- Power total motor service 15 kW (ac motor)
- Main voltage 400 v 60 Hz. –please use a transformer to lower from 440 to 400 Voltage
- Inlet wire diam. Min. 5.5mm
- Max. 10 mm low carbon wire with quality 350-370 N/mm2
- Finished wire diam. Min. 4,0mm -max. 8mm
- with quality of 500 N/mm2 with and without ribs Reduction of the raw material smooth wire with 350-370 N/mm2to a finish coil with the spec of 500 N/mm2
- it is possible to reduce the wire by max 25 % -normally we recommend 20 % reduction as it require of course more power to go to max.
- Maximum speed: Input 10,0 mm: 5 - 6 m/sec (1st pass), Input 8,0 mm: 9 - 10m/sec (2nd pass)
- Max load unwinding 2400 kg (each one)
Main electrical components used in new electronic:
PLC: FATEK
HMI: WEINTEK –Touch screen userface
Rest of electronics: Legrand, Schneider, Meler
1. VERTICAL UNWINDING UNIT FOR WIRE COIL
Structure: The structure is made of welded steel, will be reinforced to hold wild coils up to 2400 kg
Diameter of the pole is 750 mm and height 2600 mm
Wire direction: From left to right.
It consistof carrier (2 units) and strutted pole (1 unit)
2. MECHANICAL DESCALING
It is used for wire cleaning.
Structure: The structure is made of high quality steel
3. SPRAYING WIRE UNIT (MIXER)
It has box for storage of powder for calibration. Storage has rotary hand for fixing the powder.It is necessary to provide special powder for lubrication.Sprayer wire serves to reduce friction.
4. COLD DRAWING PLANT
Suitable to draw: LOW CARBON STEEL WIRE
Wire direction: Left to right
Drawing range: Inlet diameter 10mm
Speed: 5 - 10 m/sec.
Number of blocks: 1 block
The blocks are made of high quality steel cast iron. First block is designed with auto accumulation control. Auto accumulation control is set on block by inductive sensors. System maintains a level of accumulation which has set by operator. In the case of any deviation system will slow downor speed up and return wire to set accumulation. In the case of minimum deviation system will stop machine.
Sensor arm: Analog angle position sensor
Part for measuring length: Shaft encoder for measuring length and machine speed.
Cooling:
• Cassettes: water
• Block: water
Water:
• Consumption: 3-5
• Pressure: 2-3 bar
• Temperature: 20÷30 °C
• Entry of water: From left side
Drive motors: AC motors with protection. Motors speed control via high quality frequency converters
Control Techniques.
• Control system: With PLC
• Data entry: High quality industrial touch panel.
• Switch cabinet: Sheet steel construction with a high level of protection.
Machine power: Motors for block: 220 kW
5. ROLLING CASSETTES - 2 (NEW)
