Study on back-pumping keyhole-free friction stir spot welding system based on PLC control
摘要
Abstract
According to the spot welding process of back-pumping keyhole-free friction stir spot welding system,this system is designed by the combination of software and hardware.The design form of stir tool of pin and shoulder separation are presented by solving mechanical problem.At the same time,the electrical schematic diagram,the program flow chart,PLC main program instructions and HMI operation interface are given by using major components of PLC,HMI,servo m otor and current sensors.It is convenient,reliable and precise to achieve system control through the closed-loop control technology of PLC and servo motor,as well as real-time communication technology between PLC and MHI.This system has been successfully used in production and scientific research.And the results show that the system is stable and reliable.关键词
