Design and function optimization of electric control system for stud welding machine

In orderto realize the automation of large diameter stud welding, based on Mitsubishi PLC programming controller MELSEC IQ-F drive servo motor drive system and the gas dynamic device of automatic stud welding system, automatic welding process identified in the detailed analysis of the stud welding, the system gives the overall scheme is proposed. The topology of 11 PLC control three servo motors is given. The operation sequence diagram of the system is given, which provides a good operation interface. The practical operation proves that the design is feasible. For welding arc partial blow phenomenon, weld by material and the external disturbances phenomenon, take gear type double copper pole about electrode of equal contact surface, to enhance the effect of welding, installation of soft rubber to realize automatic correct contact surface of inequality, products by the manufacturers that use, welding products reached the requirements of enterprises, greatly improve the welding quality and working efficiency.
