Study Of Electrical Control System On Automatic Metal Production Lines

The high-tech promote the rapid development of traditional industries in the information age,the application of today's control theory and automation technologies in industrial automation machinery changed every day,inclouding a large number of new technologies in engineering controls.Technologe relate factories such as easy to control more precise AC servo-driven technology,a powerful programmable logic controller,the new generation of factory communications field bus technology,flexible and intuitive interface and so has universal application.As large enterprises dedicated metal-cutting assembly line,growing concern in the manufacturing process of digital,From the beginning of the PLC to the progressive development of NC control,until the current number of HMI for the operation to the media, means of communication to all bus automation devices of the times,and has become the trend of manufacturing automation.According to my company's technology needs,the research and development Z012-automatic production line equipment requirements for the production of metal processing at least 60,000 / year,cutting the processing of location accuracy of 0.01 mm.Factories on the rhythms of high demand,but also with the production of further enhancing the process beats requirements will be raised,This paper is mainly based on the content of my company's production process needs in the use of these new technologies on the basis of research and development Z012 automatic metal cutting production line electronic control system for comprehensively expounded.The content of the paper are mainly based on my company's production process needs comprehensively expounded how to research and development the electronic control system of Z012 automatic metal cutting production line with the use of these new technologies above. From the foundation theory,calculated the design parameters,determined electronic control system's hardware and software implementation in accordance with the design parameters, installation and commissioning through to the final design for the purpose.The electronic control system of automatically production line integrated with the application of Siemens S7-300 series PLC control technology,AC servo-driven technology and PROFIBUS field bus technology,through the manipulation of HMI to meet the processing requirements.Through a period of production has proved that the automated line manipulated so human and the workpiece also meet the inspection indicators of process,the electronic control system designed meet the technological requirements.
