FIELD: working or pressing of metals.
SUBSTANCE: method comprises cutting out a ring blank, shaping the bushing, and heat treatment of the bushing. The averaged diameter of the flat ring blank should be equal to the averaged diameter of the adapter. The shaping is carried out in two stages. In the first stage, the blank is shaped to provide a trancated cone whose small diameter is equal to 1.1-1.2dk, where dk is the inner diameter of the blank. In the second stage, the blank is annealed at a temperature of 300-320°C allowing it to stand for 1.0-1.5 hour. Finely, the blank is shaped in the closed space of the press, with pointing the small diameter cone upward.
EFFECT: enhanced quality and reliability.
