摘要： A method for forming hollow profiles is disclosed. In one exemplary method, a hollow profile is guided through a die in a processing direction and fixed by a mandrel such that at the die, the hollow profile has a material flow velocity in this processing direction (2), in which the method the mandrel has a drawing velocity in the processing direction that is greater than the material flow velocity.

摘要： A method for manufacturing hollow shafts having end portions of greater wall thickness and at least one intermediate portion of reduced wall thickness, from a tube having constant wall thickness. The method includes providing a mandrel having diameters stepped over its length, with a first longitudinal section having a smallest diameter and at least one further longitudinal section having a further larger diameter. Reducing the external diameter of a first portion of the tube over the first longitudinal section of the mandrel to produce the first end portion. Reducing the external diameter of a middle portion of the tube over the at least one further longitudinal section of the mandrel to produce the at least one intermediate portion. Reducing the external diameter of a further portion of the tube over the first longitudinal section of the mandrel to produce the second end portion.

摘要： 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.

摘要： A method of elongating a tube (10) by way of a drawing ring (13), wherein, when elongating the tube (10), tensile forces are applied to an elongated tube portion (22) which has already passed through the effective drawing ring cross-section and that pressure forces are applied to a tube blank portion (11) which has not yet passed through the effective drawing ring cross-section, wherein the tensile forces are applied by a mandrel (16) which is positioned in the tube and which is connected to a front tube end in a form-fitting or force-locking way.
