摘要： A method is used to manufacture a drawn tube having a hollow low interior for housing an axle shaft. The method includes the steps of placing a billet into a first die assembly and pressing the billet into the first die to producing a pre-formed billet. The method also includes the steps of moving the pre-formed billet from the first die assembly to a second die assembly and pressing the pre-formed billet into the second die assembly to produce an extruded tube. The method further includes the steps of moving the extruded tube from the second die assembly to a third die assembly and pressing the extruded tube into the third die assembly to further elongate the extruded tube and decrease the thickness of the wall of the extruded tube to of from about 3 to about 18 millimeters to produce the drawn tube having the yield strength of at least 750 MPa.

摘要： After a rod-like titanium material 20 is accommodated in a generally linear-shaped groove 13 of a first mold 7, a first guide portion 15 of a second mold 8 is fitted to the groove 13. Thereafter, the first mold 7 is moved along an arrow A direction relative to the second mold 8 fixed to an anchor block, by which the titanium material 20 substantially immovably retained in the groove 13 of the first mold 7 is bent and pushed into a through hole 24 of the second mold 8 by the first guide portion 15, thus being plastically deformed.

摘要： In a method for continuous manufacture of profiled sections material (3) is forced through a passageway (2) past the rotating die (5) to form one or several lengthwise profiled sections (11, 12). During its advancement the material (3) is forced into one or several recesses (10) formed in the peripheral face (9) of the die (5). Transverse profiled section parts (13) that are integral with lengthwise profiled sections (11, 12) are then being formed in or laterally of the profiled sections (11, 12). A device for performing the method comprises a die (5) serving as a shaping tool. The die is arranged to rotate and is provided with one or several recesses (10) in its peripheral face (9). The recess/recesses (10) are arranged to shape, in or laterally of one or several strings of material that form lengthwise profiled sections (11, 12) and are being advanced past the die (5), profiled section parts (13) that are integral with said lengthwise sections (11, 12).

摘要： An apparatus for extruding stepped extrusions, e.g. of aluminium or aluminium alloy, comprises a die holder (16a) carrying a major die (19), and a split minor die (18) arranged for abutment with the downstream side of the major die (19) and having its two halves mounted on respective parts of a split holder (17). The holder parts are movable towards and away from the line of extrusion to put together and separate the halves of the minor die (18). The die holder and the container (12) of an extruder are movable towards each other to press the minor die (18), the major die (19) and the downstream face of the container (12) into sealing engagement about the die apertures, and are movable away from each other to permit the extrusion to be sheared off between the container (12) and the major die (19).
