Main Parts of Rough Wire Drawing Line
1. Motor
a. Host machine: 30kw AC inverter motor for the first reel; 22kw AC inverter motor for the others;
b. Winding machine: 15kw inverter motor

2. Reel
a. Diameter: φ600;
b. Material: ZG45 steel; coated with abrasion-resistant tungsten carbon powder; zinc thermal spraying treatment is adopted inside the reel to prevent generation of scale; hardness: >HRC62; finish: ≤0.8Ra; thickness of coating: ≥1mm;
c. Cooling: narrow-slit type water cooling inside the reel; forced slot type annular air cooling outside the reel
d. Testing device is set behind each reel to shut the machine down when there is a broken wire

3. Mold box
a. Universal direction adjustment
b. Comes with 2 cavities separately for lubrication and cooling water (direct water-cooled open mold); the powder won't spill out into the water cavity which is covered with a cap
c. Mode hopping device is adjusted at inlet of the box
d. Optional rotary box

4. Tension adjustment roller
Tension adjustment process is done pneumatically. Made from Aluminum and coated with carbon tungsten, all of the guide wheels are given 4 years' guarantee. The sensor from TURCK adopts non-contact angular displacement. Mold is compensated automatically after it is worn.

5. Transmission style: joined V belt

6. Cooling system
a. Temperature of the reel is kept lower than 60℃ when the equipment is running
b. A liquid level indicator is available for the backwater system

7. Pneumatic system: from AIRTAC

8. Transmission system: the bearings are from NSK

9. Control system
a. PLC and fieldbus control system; each machine is set with the operations of start, front/back linkage, stop, and emergency stop
b. Users can preset the length, speed, check the error, machine condition, set the mold and draw the wire through the HMI, as well as control drawing machine singly or in series
c. Speed of the system is adjustable. Operations of unwinding, winding, and drawing can stop immediately when there is an emergency stop
d. A wire cutting device is set at the adjustment roller. When the wire is broken, the mechanical and pneumatic devices will detect simultaneously and trigger an emergency stop. The system will alarm automatically and show where and why the errors arose.

10. Winding system
a. The main transmission unit adopts single-stage B type belt; cylinder is set at bottom of the winding machine to motivate the wire winding wheel
b. Pneumatic braking and driving device is available
c. 15kw inverter motor
d. Welding Wire is arranged pneumatically with the interval smaller than the wheel inside width
e. φ800 winding wheel, replaceable conic end
f. Tension detection: non-contact sensor from TURCK
g. Safety door is available

11. Safety system
a. The machine won't start when there is an open protective shield, unreset button, or insufficient air pressure
b. Auto stop in case of broken wire
c. Emergency rope pull switch
d. Emergency stop button on the main console; emergency stopping time: ≤5S; quick stopping time: ≤15S; normal stopping time: ≤30S

12. Function description
a. Drawing machine: start, stop, broken wire detection, protective shield detection, tension adjustment, water volume adjustment, etc.
b. Console: start, stop, emergency stop, accelerate, decelerate, error indication
c. Control buttons for water, electricity and gas, and emergency stop buttons are set in front of the machine
d. Touch screen: setting for wire diameter, speed, length (machine will stop automatically when the required length is met), tension, reel cutting, error indication, and PLC-I/O module

13. Operating system protection
a. Protection for undervoltage, overvoltage, open phase
b. Error protection inside frequency converter
c. Reel protection and broken wire protection
d. Protection for unusual open of protective shield
e. Overheat protection for motors
f. Emergency stop and other failure protections

14. Wire fixing roller and new mode hopping manner

15. Gate structure for lower part of drawing machine
