FIELD: machine engineering, namely apparatuses for finishing and strengthening parts by surface plastic deforming.
SUBSTANCE: apparatus includes mandrel, wave-guide, striker and changeable deforming members. Wave-guide and striker in the form of rods are mounted along central lengthwise axis of mandrel. Striker is mounted with possibility of acting upon wave-guide for transmitting cyclic pulse load. Changeable deforming tools are mounted in plungers arranged along radiuses and supporting sets of plate springs for applying static load normally relative to worked surface. Helical cylindrical compression spring is mounted in apparatus for acting upon free end of wave -guide having cone surface engaged with free ends of plungers.
EFFECT: enlarged manufacturing possibilities of static-pulse rolling out.
