This device uses electrodes to clamp the two ends of the formed stabilizer rod, and relies on the resistance of the stabilizer rod itself to achieve heating. The heating speed is fast and is not affected by the shape of the stabilizer bar. One machine can heat various shapes of stabilizer bars. The equipment power supply adopts the HULR series low impedance heating power supply independently developed by our company. Compared to the power frequency controller, the intermediate frequency AC controller has a shorter response time, high control accuracy {power frequency/cycle, frequency conversion/millisecond}, and a wide applicable range of power grid voltage {+10%/-20%}. The controller receives PLC simulated voltage signals, adjusts the transformer input power through PWM method, controls the size of heating current, and adopts KUR feedback mode, The advantage of having a constant power output
