Abstract
A device and a method for axially forming an elongated hollow body is disclosed. The device has at least one receptacle, a reducing die, a punch for pressing the elongated hollow body through the reducing die in the direction of an axis, an expanding mandrel and means for limiting the axial displacement of the punch. The punch and the expanding mandrel are movable on the same axis and the expanding mandrel is arranged inside the punch. The hollow body is reduced to a first diameter in a first portion and expanded to a second diameter in a second portion as a result of a movement of the punch and the expanding mandrel in the same direction.
