FIELD: process engineering.
SUBSTANCE: invention relates to metal forming and may be used for deformation of long tube billet ends. Proposed press comprises tubular bed, power unit studded thereto, split die and tubular billet clamp. Said clamp is made up of fixed adapter with tapered cavity accommodating segments. Said segment work surface is notched and thrusts against support surface formed by insert with plate spring. Power unit is made up of main cylinder with rod incorporating piston and extra cylinder rod. Extra cylinder rod end supports the case with moving adapter rigidly jointed therewith. Said moving adapter has tapered cavity with taper reverse of that of fixed adapter tapered cavity. Split die is accommodated in moving adapter cavity with clearance between ends faces of its segments and clamp segment faces.
EFFECT: precise alignment of deforming tool and split die, higher reliability and deformation quality.
