Abstract

FIELD: metal pressure forming, namely, apparatus for expanding tubes in tube walls. SUBSTANCE: apparatus includes power cylinder 1, whose rod 2 supports spacing unit with slit-type collet chuck 5. Arrangement of elastic member 7 for performing tube expansion in annular turning of slit-type collet chuck 5 on separating sleeve 6 wound with overlapping from springy material strip provides fixation of elastic member 7 in axial direction and elimination of possibility of metal flowing in slits of collet chuck 5. EFFECT: enhanced reliability of apparatus due to increased service life of elastic member. 1 cl, 1 dwg
