FIELD: working of metals.
SUBSTANCE: invention relates to processing of metals by pressure and can be used in radial forging of pipes on a mandrel. The mandrel is retained in the deformation area by manipulators. The pipe is retained and moved to the deformation area by means of two manipulators to ensure plastic deformation of the pipe. The mandrel is therein first retained by one manipulator while retaining and moving the pipe into the deformation area by another manipulator, then the functions of the manipulators are switched.
EFFECT: productivity in production of pipes by radial forging is increased as a result.
