Abstract


With the increasing annual production of rolling stock , the quality requirements of its steel and welded structure more and more strict , while China is still in its infancy in railway locomotive parts plane straightening , artificial straightening as well as traditional hydraulic control technology can not meet the needs of the industrial production . The current status quo in the CNR Dalian Locomotive Works research based on the integrated use of modern design method as well as the advanced industrial control technology , research and design of the 500 tons steel straightening machine hydraulic control system , retaining the traditional manual operation base on , the automatic control mode PLC master core . The hydraulic machine is mainly composed by three parts of the mechanical structure , electrical control and human-machine interface . This paper first introduces the hydraulic machine hardware components of the body's structure , given the design and realization of the main circuit of the hydraulic pump station slide master circuit ; constructed by analyzing hydraulic machine process control requirements , the programmable controller and touch screen - based hydraulic control structure of the system as a whole , given specific instructions and complete the design of the PLC program and HMI PLC inputs and outputs configuration and use of special function modules . Composition of the steel straightening machine , hydraulic control system hardware consists of a pump station, the main control unit of the PLC , the oil temperature control and oil pressure detection and lubrication system ; software section includes touch screen with Mitsubishi GT Designer configuration software design and Mitsubishi PLC control procedural design . The section steel straightening machine via the operator panel to be completed on the lower stroke , temperature alarm , parameter setting and the pressure head fast , slow down , pressing, packing, return process action . The device is through on-site commissioning, and has been put into production use , currently running in good condition .
