4.12 Payoff stand consists of column, cantilever and steering roller.
4.13 Height of the column is 5000mm or so. The two aluminum reels can achieve continuous
pay off.
4.14 On the top of the column, there is an emergency stop device for the whole assembly.
4.15 The cantilever is 1700mm length.

4.2 Main drawing machine
4.2.1 Type: slip type. 13-die copper wire drawing machine with drawing blocks of the same
diameter
4.2.2 The machine consists of trough for cooling and circulation of drawing emulsion, gearbox,
lubrication system, constant speed wheel, main motor and the motor for the constant
speed wheel.
4.2.3 Four clip-and-run switches for die stringing by clip-and-run operation. Device to prevent
from back turn is offered.
4.2.4 The drawing block and drawing die holder extend identical distance from the body of
gearbox. This special construction results in good rigidity of spare parts significantly.
4.2.5 Drawing blocks adopt steel wheels. Its surface is covered by tungsten carbide to prolong
its use life.
4.2.6 Dies can be changed quickly. In need of the change of product size, we can just add or
Reduce high speed drawing dies, which reduces the types of drawing dies.
4.2.7 The gearbox is lubricated by a oil pump with a 2.2?＝4.4kw. motor. All the gears and
Bearings are lubricated by a heat exchange.
4.2.8 The drawing emulsion trough is provided with double doors made of stainless steel,
which prevent lubricant from overflowing.
4.2.9 The drawing blocks and drawing dies are lubricated and cooled by immersion and
spraying. Drawing emulsion supply and heat exchange cooling system is also offered.
4.2.10 In order to prevent the machine from working without lubrication, an alarm for absence
of oil is provided. When a signal of absence of oil is sent, the whole machine will stop.

4.3 Annealing device
4.3.1 Type: horizontal DC annealing
4.3.2 Diameter of annealing inlet wire : 1.2 mm?mm
4.3.3 Max linear speed of annealing 23m/s
4.3.4 4-Diameter of annealing nickel-conducting ring: 450(three conducting rings
are exchangeable)
4.3.5 The stretching force of softening conductor is even and stable and reaches
the international requirement of the stretching rate.
4.3.6 Annealing is a two-period process: preheating period and annealing period, and
the elongation of copper wire has been considered the conducting wheel speed
of each period.
4.3.7 Softening room is protected by steam with hand-operated pressure regulating
valve.(The pressure of steam is 0.2Mpa) the dosage is 20kg/H.
4.3.8 The exit is equipped with air-drying device which is hand-operated.(The
pressure 0.2~0.4MPa)the dosage is 30 m3/H.
