1. General description
1.1 This machine is used to draw Φ1.2-Φ3.5mm copper wires. Tandem cabinet combined mechanism, each wire capstan driven by independent servo motor. Due to fully-immersed drawing basin, take good wire cooling effect.
1.2 Cost saving: Saving electrical energy 20%, due to slightly slip-rate design. Could power off no work motor and save energy up to 20%. By slightly slip rate design, increasing the service life of drawing die, capstan and drawing lubricant oil consumption. High speed and save energy 20% than gear type.
1.3 Enhance production ability: Using independent motor drive technology, when changing the diameter of the outlet, the process of rapid die change system is realized; the human-computer interaction interface is used, and mechanical indication and electrical fault display are provided, which can reduce downtime. The eye mold elongation can be flexibly adjusted according to the production requirements.

4. Detailed introduction:
4.1 Payoff stand
1) Type: cantilever type
2) Payoff stand consists of column, cantilever and steering roller.
3) Height of the column is 4500mm or so. The two aluminum reels can achieve continuous pay off.
4) On the top of the column, there is an emergency stop device for the whole assembly.
5) The cantilever is 1700mm length.
4.2 Main drawing machine
1) Type: Slightly slip-rate design. 13-die copper wire drawing machine with drawing blocks of the same diameter.
2) Tandem cabinet combined mechanism, each wire capstan driven by independent servo motor.
3) Due to fully-immersed drawing basin, take good wire cooling and lubrication effect.
4) High quality surface of the wire, because the design of capstan and the center line has inclination angle.
5) Drawing blocks adopt steel wheels. Its surface is covered by tungsten carbide to prolong its use life.
6) The rapid dies change system, no need to change all the dies, save a lot of time.
7) Drawing emulsion supply and heat exchange cooling system is also offered.
8) Precision helically gears for extremely smooth operation and homogeneous load transmission. 9) Low noise operation and no need enclosures.
4.3 Accumulator
1) Capacity of the accumulator: 7m
2) Max. Tension: 138N
3) Tension is regulated by air cylinder pressure
4.4 Annealing device
1) Type: horizontal DC annealing, speed tracking automatically
2) Diameter of annealing inlet wire: Φ1.2 mm-Φ3.5mm
3) Max linear speed of annealing: 25m/s
4) 3 pieces-diameter of annealing nickel-conducting ring: 450mm (three conducting rings are exchangeable)
5) The stretching force of softening conductor is even and stable and reaches the international requirement of the stretching rate.
6) Annealing is a two-period process: preheating period and annealing period
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.
8) The exit is equipped with air-drying device which is hand-operated. (The pressure: 0.2~0.4MPa) the flow is 30 m3/H.
9) Annealing cooling adopts water circulatory cooling. Heat exchanger is cooled by the water. Flow is 30 m3/h.
4.5 Φ800 Automatic spooler (Double position)
1) Spooling bobbin size: PND800
2) Max. take up speed: 25m/s (PND800)
3) Take-up motor: 37KW (two, AC)
4) When reels need to be changed, the speed will slow down in order to decrease rotating inertia and shorten brake time. Brake is pneumatic butterfly type.
5) Traverse pitch can be adjusted freely
6) Reels can move up and down controlled by air pressure. The gripping and relaxation for reels is pneumatic control with mechanical lock.
7) For reel change, the length counting wheel will send a signal in accordance. With the pre-set length to realize it. The reel change accuracy in the course of the exchange from filled reel to empty reel is up to 99%.
4.6 Pointing machine
