Analog signal and automatic operation of straight wire drawing machine
With the improvement of mechanical processing technology, the control technology of frequency converter is also being vigorously promoted and applied. Straight wire drawing machines have also been widely used in the production of PC. Other straight wire drawing machines are widely used in some domestic manufacturers of welding materials.
The straight wire drawing machine equipped with a variable frequency speed regulation system has excellent technology and significant energy-saving effect. The speed range is 30:1 during normal operation, and can provide more than 1.5 times the rated torque at 5% of the rated speed. The system logic control of the straight wire drawing machine is rather messy, there are various linkage links, which are completed by PLC and do not rely on external control.
The straight wire drawing machine determines the operating speed according to the operator's panel setting. The analog signal of this speed enters the PLC, and the PLC outputs the analog signal at a certain slope after considering the acceleration and deceleration. The purpose of this is mainly to satisfy the needs of some operations such as inching and threading.
The analog voltage signal output by the PLC is connected to the AI2 input terminals of all inverters as the main speed reference signal. The signal of each swing arm displacement sensor of the straight wire drawing machine is connected to the corresponding drum drive frequency converter as the feedback signal of PID control. According to the position of the swing arm in the middle, set a PID setting by yourself. This system is a very typical PID control system with feedforward, one stage is cascaded one stage, and PID is used as the fine-tuning quantity.Discount Drawing Machine
