Drum 
Material:steel ZG45~55, hardness alloy tungsten carbide is spraying-painted on working surface, with HRC60, roughness ≤1.6Ra.
Drum using life: two year
Drum cooling mode: narrow seam type water cooling for inner of drum

Die box
Welding part is adopted for the die box. It is adjusted in universal directions.  The guide roller is in front of die box and coated with tungsten carbide. The die box is divided into lubrication cavity and cooling cavity. Ball valve adjusts water feeding flow. The position of die box can be adjusted to adapt the position of wire for drawing. The dancer arm wheel is in the entry of die box to adjust the drawing speed of every drawing block. It is driven by pneumatic cylinder.
Tension roller is made of special steel alloy and heat treated to have long working life.
The wire tension is detected by the TE sensor(none touch type) dynamically and feedback signal to the motor driver. 

Electric  Control  system
Control System adopts AC frequency-variation speed adjusting drive and Siemens PLC system, and takes the most popular PROFIBUS type in the world, which not only operates stably and precisely , but also greatly improve the transit speed.
Operation: including touch screen, emergency button  ready button, stop button, accelerate button, decelerate button, fault button and reset button. Touch screen is colorful and the brand is Weinview . The yield can be presented on the screen by the meter-counter or weight-counter. The drawing speed can be adjusted on the screen.


Control pulpit
a. On pulpit, all drawing drum running conditions can be displayed.
b. It can control all drums and the single taking-in machine by linkage.
c. It can regulate the running speed by integration.
d. At EMG stop, it can realize the integrated linkage and EMG stop for paying-off, drawing and taking-in, also ensures no wire confusion, no breaking.
e. Automatically alarm when failure displays and display the locations where the trouble may take place and the causes.  
Inverter:SINE inverter is adopted.



Working mode
The system adopts the PLC control, inverter and contact screen generally. The digital exchanging is completed by communication. PLC is used to read, write, start and stop the inverter at will. PLC software ensures the auto program editing and setting for different drawing technics and ensures the running smoothly. Color screen man-machine interface system can monitor equipment running status and failure display. All technics parameters of system can be input from contact screen with high precision, strong correctness and easy modification. It also ensures the wide drawing technics and easily realizes the die jumped drawing. The whole system runs reliably with low failure rate and easily operation.
