摘要
顶杆小车电气控制系统对保证锥形辊穿孔机的正常高效运行具有重要作用。介绍了立式锥形辊穿孔机顶杆小车电气控制系统的硬件组态、直流传动装置与PLC的通信及其软件编程等。S7-300型PLC的应用对精确控制顶杆小车的定位及过程速度起到良好的作用。
The electrical control of the thrust block is regarded as so critical for ensuring normal and highefficiency operation of the vertical cone type piercer（CTP）proper.Described here are the main aspects of the said thrust block electric control system,including the hardware configuration,the DC drive unit,and the PLC communication and related software programming,etc.The application of the S7-300 PLC plays a satisfactory role in precision-control of both positioning and process speed of the thrust block.
