≥0.6MPa） （8）Motors：first draw *0KW, others *2KW AC
freq. con. motor （9）Drum of drawing
machine： ① material：steel ZG*5~*5, hardness alloy tungsten carbide
is spraying-painted on working surface, with HRC*0, roughness
≤1.6Ra. ② Drum using
life：twoyear ③ Drum cooling
mode：narrow seam type water cooling for inner of
drum （*0）Die
box：
Welding part is adopted for die box,
the spraying-painted tungsten carbide is adopted for the surface
of guide wheel and guide roller.
The die box is divided into lub. powder
cavity and water cooling cavity (water flowing automatically for
cooling)
Die box is adjusted in universal
directions.
(*1) Electric Control
system ①Arrangement (We can
arrange them as customers' require) a. Inverter：SINEinverter is adopted. b. PLC:：Siemens S****0 Series (made in
Germany) c. Sensor：DING CHEN Brand d. Low voltage electric appliances including
relay：Chint
Brand e. Contact screen：Weinviewcolor contact screen
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 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. 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 confusion, no breaking. e. Automatically alarm when failure displays
and display the locations where the trouble may take place and the
causes.
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.Color screen man-machine interface system can
monitor equipment running status.All
technics parameters of system can be from
contact
screen with high precision.
