FIELD: plastic working of metals, namely by means of energy of electric explosion of metallic connector in condensed media.
SUBSTANCE: apparatus includes dielectric sleeve with transfer medium hydraulically insulated by means of rubber plugs. In cavity of said sleeve are arranged: rigid carcass in the form of two end walls mutually joined by means of metallic studs; and exploded metallic conductor. The last is divided by two parts connected one with other through electrode. Electrode rests upon dielectric sprockets and it is in the form of body of revolution whose shape is described by function defining length and diameters of electrode according to linear dimensions of deformed portion of tube. Relation of maximum diameter of central part of electrode to inner diameter of dielectric sleeve is in range 0.5 - 0.8. Curvilinear surfaces of end walls of exploded conductors are in the form of paraboloid. Boundary ends of exploded conductor are arranged in focal point of paraboloid.
EFFECT: more effective usage of energy of electric explosion of metallic conductor, enhanced quality and reliability of tube pressing-in, improved efficiency of apparatus.
