The drawing speed of each drawing head of the in-line drawing machine is superposed by the main speed and PID fine adjustment. Each drawing head is equipped with a displacement sensor on the tension balance bar to dynamically measure the metal wire between the drawing heads. Tension, the displacement sensor output standard signal, as the feedback of the inverter tension closed-loop PID control, by adjusting the motor speed of each level, the system ensures that the tension of each tension detection point is constant. Only when the tension of each point is kept constant during the entire drawing process, can it be ensured that the multi-level continuous drawing can be performed smoothly and the quality of the metal wire can be pulled out.
Drawing host: Select JEVA311A series wire drawing machine special inverter, one, current vector control, low frequency and high torque output, low speed wear mode, stable speed, smooth start-up process, stable high-speed operation. Winder: Select JEVA309A series tension control inverter, one, tension closed-loop control, tracking wire drawing machine output line speed operation. Current vector control, built-in braking unit and disconnection protection function, install braking resistor according to motor power.
The above are all dedicated inverters, basically do not need to reset the parameters, and the factory value can meet the process requirements.
