In order to improve the security and reliability in the process of producing steel, a servo motor control design of reinforced bending equipment was provided, which include PLC control unit, servo motor, bending servo motor, solenoid valve, cylinder, signal acquisition unit and a touch screen. The signal acquisition unit included the photoelectric switch, magnetic switch and the switch button of the bending equipment. The servo motor control strategy was implemented by PLC controller motion control technology and data processing technology to realize the full digital control equipment, where servo control technology was used to achieve the accurate and efficient movement of the equipment and the energy saving in the process of production. A more humanized operation interface was included for easy operation and bending accuracy. The system accomplished not only high efficiency, energysaving, but also considerable reduction of the labor intensity and the rejection rate, whereby lowers the cost.
