The Overall And Control System Design For Rail Derusting Machine

The high-speed railroad and the orbital transportation's development, requests the rail long axle, seamless, accurate, ensures the transport of both travellers and goods security, high quality, fast. However, When rails welded together, welding tumors will exist in the welding head. In order to make the top and sideworking edge flatness of within lm welding meet the requirements, welding tumors must be removed. Also because of the replacement of Obsolete equipment of each Railways Bureau, and to meet the requirements of quality, efficiency and so on, equipment will be designed to numerical control equipment. This project mainly studies the CNC precision grinding rail, which grinds the top pf both sides and side working edges of welds, to reach to the face required flatness and other requirements.The core of the main controlling system is Mitsubishi FX3U series PLC. When the rail weld joint position examines unified the digital quantity and the simulation quantity mix transformation module, completes the control work highly effective. At the same time,distributed terminal signals on the system using Mitsubishi CC-Link bus transmission technology,make the system compact and the signal transfer is stable and safe. In addition, taking into account the stability of the system the whole equipment has also made anti-interference designs.In the entire system of software design using the modular design concept,the programs can be directly invoked by other programs.Enable the design process can be complete by a division of labor.The langue of the program is ladder diagram which can be maintained and read easily.Through designing the test and control system the degree of automation is improved.Operate easily and reliably.At the same time can be efficient, high-quality completion of the work of Rail weld joint correct grinding.
