The invention discloses an intelligent cross wedge rolling control system based on data driving. The intelligent cross wedge rolling control system based on data driving comprises a DCS control unit, a PLC closed-loop control unit, a quality management unit and a robot. The DCS control unit is used for acquiring control parameters, equipment state information and production data, performing setting calculation on the basis of the control parameters and the equipment state information, transmitting a calculation result to the PLC closed-loop control unit, and transmitting the production data to the quality management unit; the PLC closed-loop control unit is used for collecting and processing a production process signal and carrying out driving control on the robot; the quality management unit establishes a quality regression prediction model on the basis of the production data, and performs quality management on the cross wedge rolling production process on the basis of the quality regression prediction model and a particle swarm optimization algorithm; and the robot is used for achieving intelligent control over different cross wedge rolling processes. According to the intelligent cross wedge rolling control system based on data driving, high-precision intelligent control over cross wedge rolling is achieved, so that high-efficiency, high-quality and automatic production of shaft products is achieved.
Description
technical field [0001] The invention belongs to the technical field of intelligent control of cross wedge rolling, and in particular relates to a data-driven intelligent control system of large shaft cross wedge rolling and intelligent control of production processes. Background technique [0002] Cross wedge rolling is a new forming process for shaft parts, and it is an integral part of advanced metal forming manufacturing technology. According to different requirements for product performance and quality, the main process flow is not completely the same. The main process of a complete cross wedge rolling specialized chemical plant The process is: long bar material → cutting to length → heating → rolling → air cooling → normalizing → shot blasting → straightening → inspection. In recent years, the recording and collection of industrial process data has become more common due to the widespread use of distributed control systems and new measurement techniques. At the same ti...
