Abstract: The device for ultrasonic machining of articles in a liquid medium comprises two groups (2, 3) of acoustical-electrical transducers (4) arranged on an elastic element (7), filled with a liquid medium (8), in staggered order at a predetermined distance from articles being machined. The acoustical-electrical transducers (4) of the group (2) are connected to the output of an ultrasonic generator (1). The acoustical-electrical transducers (4) of the group (3) are connected to the output of the ultrasonic generator (1) through a phase-pulse modulator (5) connected to a saw-tooth voltage generator (6).

Abstract: A method according to the present invention comprises the formation of metallic materials by translating metal wire between working tools, that is, a striker and an anvil, which are arranged in a closed space with a medium inert to both the wire metal and material of the tools. The wire is then heated to a temperature high enough for plastic deformation of the metal, while ultrasonic vibrations are simultaneously applied to the working tools, propagating at an angle to the longitudinal axis of the wire. An apparatus for carrying out the proposed method comprises, in addition to the working tools, sources of ultrasonic vibrations which are rigidly coupled to the tools, and a mechanism for heating the working tools and wire.
