Abstract
FIELD: plastic metal working, cold stamping with use of pressure of elastic medium to manufacture extremely thin-walled members of piping systems. SUBSTANCE: filling agent is put into tubular skelp 9 with positioning of end parts 5 by points 8 of narrowing of rigid members 6 over sections of its transition to expanded part and central part 7 over section of maximum expansion. Then skelp is placed into impression of matrix 1 of stamping gear. In process of upsetting of skelp with filling agent there is created internal pressure of elastic medium which is distributed differentially over internal surface of skelp depending on degree of expansion. This makes it possible to manufacture extremely thin-walled articles of complex design with simultaneous decrease of rejects. EFFECT: reduced difference of internal pressure of elastic medium on sections of transition of skelp into expanded part. 1 dwg
