FIELD: metallurgy.
SUBSTANCE: tube blank comprises a deformable part rigidly connected by means of a coupling with allowance for machining and technological allowance for installing the blank on the machine and directing its movement when bending. At that, the coupling has a body with grooves and slide blocks fixed in the grooves by means of locking rings, between which the compression springs are installed, which provide fixation of deformable part of the blank through slide blocks during its movement when bending.
EFFECT: expanded technological capabilities.
