conversion wire drawing machine is difficult and the cost is not low. Therefore, the double frequency conversion wire drawing machine adopts PLC non-contact detection and data processing to accurately control the running frequency of the two motors to ensure constant slip. It has the characteristics of low failure rate and high running speed. It has become the development direction of ultra-fine wire drawing machine in the future. 2、 Double frequency conversion wire drawing composition
As shown in the figure below, the unwinding is free unwinding, and the speed of wire drawing is input to AI2 through potentiometer to control the speed of the whole machine. PLC calculates the pulse difference by detecting the pulse density of the constant speed wheel and guide wheel, and controls the frequency of the take-up frequency converter to ensure the constant slip. Because the outgoing wire of the ultra-fine wire drawing machine is very thin, using the swing rod to detect the tension will cause wire damage, and the runout of the swing rod is also very easy to break the wire. Therefore, compared with the traditional water
