This topic design the PLC control system of automatic shearing production line, the main work is in: a, introduces the position and working principle of automatic shearing production line. The whole production line consists of decoiler, feeder and press of three parts. Uncoiler driven by frequency converter. Feeder driven by servo motor。 Punch in sheet metal stamping forming. Second, according to the production process flow, design the control system. Of PLC, frequency converter, servo driver/servo motor selection and touchscreen devices such as。 Third, according to the production process requirement, design the control program, including touch screen and PLC program. Fourth, plete system overall debugging. System normal operation, the feed length set the touch screen, PLC pulse number according to the set value calculated, after send servo driver, servo motor control feeding, so as to realize precise servo positioning. Ensures that the feeding machine, high precision and high efficiency, precision reaches 1 m + / mm, fully meet the practical requirements. Key words: PLC; Servo Driver/ Servo Motor; Frequency Converter; Touch Panel.目錄 III 目 錄 摘 要 .....................................................................................................................I Abstract .................................................................................................................
