The invention provides an ultrasonic solidification-friction stir composite added material manufacturing device and an application method. The ultrasonic solidification-friction stir composite added material manufacturing device comprises a shell, a
machining mechanism, a
metal foil conveying mechanism, a driving mechanism, a
cutting mechanism, a movable steering mechanism, an
extrusion mechanism,an adjusting mechanism and locking universal wheels; the
machining mechanism is fixedly connected into the shell; and the
machining mechanism comprises a
numerical control machining center, a controlpanel, a machining cavity, a substrate, a first electric slide rod, a first electric slide sleeve, a mounting plate, a connecting plate, a machining head, a
transducer, an amplitude change rod, an insulation sleeve, a first cylinder, a first
piston rod and a friction stir head. The ultrasonic solidification-friction stir composite added material manufacturing device can prepare high-performance
metal samples; the mechanical performances of the samples are higher than forgings by 20-50%; and the device is low in size limiting, can
machine large-size complex-structured parts, can from more thantwo
metal materials according to working conditions and typical performance requirements of parts, and realizes preparation of heterogeneous /
gradient function materials.
