Study of the combined pulse power source of ultrasonic vibration assisted arc machining
The successful application of ultrasonic vibration assisted arc machining technology can solve the long-standing technical problem of hard-facing materials processing which machinery manufacturing industry generally faces, so it has huge potential in the field of high hardness, high strength and difficult processing conductive materials.And, the technology of the combined pulse power source of ultrasonic vibration assisted arc machining has been playing more and more significant role in ultrasonic vibration assisted arc machining processing.In the first place, on that basis of ultrasonic vibration assisted arc machining processing principle, machining process and processing efficiency affected by the parameters of pulse power source were analyzed and discussed,The original independent ultrasonic generator and arc machining pulse power supply were integrated,new functions were expanded on the basis of the original pulse power supply, which provides theoretical technical and experiment support for efficient arc machining power supply.Based on the technological characteristics and design requirements of the ultrasonic vibration assisted arc machining, the design scheme of combined pulse power sources overall system was put forward.As follows,the analysis of the pulse power supply and ultrasonic generator structure is analyzed, and then,the shared parts like chopper and rectifier was combined,the new efficient combined processing power structure was made up,using modular methods to design hardware modules,such as,DC/DC transformation module,chopper module , that form a new and efficient combined processing power structure.The use of combined pulse power source can effectively improve the machining efficiency and machining accuracy of ultrasonic vibration assisted arc machining.
