The Study Of Control System On Flashing Butt Welder For High-tensile Steel Chains Based On PLC

At present, Our coal mine machinery development more and more quickly, the demand of rings chain is rising. In recent years flash butt weld technology application have the new progress,but high strength flash on welder and Automatic control has become a difficulty, Needs to be more research and implementation deeply.In this, use PLC200 of Siemens, Studied the control system for welding machine flash.Based on the analysis of the flash butt weld technology principle, design the control system of hydraulic pump by PID compound algorithm, Improve the oil cylinder speed. Introduced the detection principle of welding current,hydraulic pressure,temperature and the location for the sliping,at the same time the controller used PLC200 of Siemens,design the analogue and digital quantity parts of controller. Realize the welding process of heating, compaction, welding, top and reset five process by software programming, it adopts the WEINVIEW industrial touch screen to PC part, Introduced the main interface and start parameter establishment,real-time curves and fault inquires interface.A lot of experiments show that it can realize welding process of all control by PLC, improved the system reliability and stability, at the same time by the use of touch screen, replace the traditional methods of operation, operation up more forthright, access the operation parameters are more timely and convenient, Enhanced the production efficiency.
