Galvanized Steel Wire Drawing Machine1

 LZ8/560 Straight Line Drawing machine (Group)  

1. Equipment comprising

(1) LZ8/560 Straight line wire drawing machine (group)

(2)  XB600 trunk take-Up machine

(3)  Man-machine interface control contact screen

(4)  Whole set of electric console

2. Main technical parameter ( key points)：

  （1）Max. entering (steel) wire strength：<700MPa

（2）Max. entering (steel) wire dia.：Ф5.5/7.0mm(20MnB4 for bolt wire making)

（3）Min.outlet (steel) wire dia.：Ф2.13/3.0/(from 7.0 to 5.0/6.5)mm

（4）drawing steel wire material:low carbon steel

（5）Max. steel wire drawing speed：12m/s ( Normal speed: 8m/s-725KG/H for 2.13mm)

（6）Water volume ：6m³/h        （Water pressure ≥0.25MPa）

（7）Air volume：1.5m³/h          （Air  pressure ≥0.6MPa）

（8）Motors：①drawing unit:30KWX1+7X22KW   AC freq. con. motor

 ②Take-Up unit:15KW           AC freq. con. motor

（9）Drum of drawing machine：

① material:steel ZG45~55, hardness alloy tungsten carbide is spraying-painted on working surface, with HRC60, roughness ≤1.6Ra.

②Drum using life:two years freely changed

 ③Drum cooling mode:narrow seam type water cooling for inner of drum.

（10）Die box：

①  Welding part is adopted for die box, the spraying-painted tungsten carbide is adopted for the surface of guide wheel and guide roller.

②  The die box is divided into lub. powder cavity and water cooling cavity (water flowing automatically for cooling)

③  Die box is adjusted in universal directions.

(11) Electric Control system ①Arrangement

a. Inverter:INOVANCE inverter is adopted.

b. PLC: INOVANCE brand is used

c. Sensor:Germany imported TURCK brands

d. Low voltage electric appliances including relay:Schneider

e. Contact screen:Taiwan color contact screen

② 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 technical and ensures the running smoothly. Color screen man-machine interface system can monitor equipment running status and failure display. All technical parameters of system can be input from contact screen with high precision, strong correctness and easy modification. It also ensures the wide drawing technical and easily realizes the die jumped drawing. The whole system runs reliably with low failure rate and easily operation. The first two are gearbox, the other is belt.

③  G.  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 will be in disorder, no breaking.

e. Automatically alarm when failure displays and display the locations where the trouble may take place and the causes.  

（12）Take-Up machine：

① the trunk take up block is 600mm

② the take up basket size is Ф860X460X1180mm

③ the working pressure is 0.4-0.45MPA

④ We will arrange more of the basket rack for shift take up and for cook

⑤ The motor is 15KW
