SUBSTANCE: method comprises cutting the ring blank out of a sheet, shaping the bimetallic adapter, and annealing the bimetallic adapter. The blank is shaped as an elongated ring whose centerline length is 0.98-0.97 of the averaged diameter of the bimetallic adapter. The blank obtained is shaped to provide a tube whose longitudinal section should correspond to the profile of the longitudinal section of the bimetallic adapter. The tubular blank is expanded . The die comprises top and bottom plates, punch, and die member provided with conical parts and main parts in the form of bimetallic adapter. The punch and die member are provided with transverse grooves.
EFFECT: expanded functional capabilities.
