Abstract:
Ultrasonic coffin manufacturing technology was widely used in the field of function and rapid preparation of composite materials, in order to overcome the power constraints of existing ultrasonic additive manufacturing equipment, a manufacturing equipment of high power ultrasonic assisted heat increment was developed. The finite element simulation software COMSOL5.0 was used by the aided design of ultrasonic vibration system. The equipment is composed of ultrasonic vibration system, pressure mechanism, support walking mechanism and heating module, the symmetrical structure is used by the both sides of welding head, the double transducer series push-pull technology is used, the single ultrasonic welding power is greatly improved. At the same time the extra heat input is provided by the auxiliary heating module, and improve the temperature of the metal being soldered. And the ultrasonic incremental rolling welding test of multi-layer copper foil is carried out. The results show that the heat-assisted ultrasonic additive manufacturing equipment has excellent welding performance and welding quality.
