The specification discloses a nonferrous extrusion system and process providing improved transfer of extrusions from the runout table to the cooling table. The runout table includes interleaved runout rollers and transfer rollers that are vertically shiftable with respect to one another. The transfer rollers additionally are horizontally shiftable between the runout table and the cooling table. The runout table receives extrusions in a longitudinal direction. The vertical and horizontal shifting of the rollers is controlled to transfer the extrusions from the runout table to the cooling table.

A stretching machine for extruded profiles comprises a stretching head capable of translating along a predetermined direction (X) on a basement and actuation means for translationally actuating the stretching head with respect to the basement. The actuation means comprise a mechanical drive comprising at least one motor element, which is integral with one of said stretching head and said basement, and at least one driven element, operatively connected to the at least one motor element and integral with the other of said stretching head and said basement, and an electric motor operatively connected to the motor element of the mechanical drive.

In production of aluminum alloy members by a plastic working of a heat-treatable aluminum alloy extrusion, cracking during the plastic working is eliminated or minimized at low cost as compared with techniques including solution treatment or restoration treatment. An aluminum alloy production system includes an extruding press, a cutting device disposed downstream from the extruding press, and a conveyer and a plastic working machine each disposed in parallel with the extruding press. The extruding press hot-extrudes a heat-treatable aluminum alloy to give an extrusion. The cutting device cuts the extrusion to a predetermined length and isolates the extrusion from the extruding press. The conveyer conveys the extrusion to the plastic working machine, where the extrusion has been cut by the cutting device to a predetermined length. The plastic working machine imparts a plastic working to the extrusion conveyed by the conveyer to form the extrusion into an aluminum alloy part.

A method for calibrating a metal profile blank configured as a hollow-chamber profile having at least one solid wall. A pressing tool is closed in a main direction about one end region of an element of the profile blank until surfaces of the pressing tool lie against a pair of surfaces of the profile blank to be calibrated, deforming and bending the at least one end region of the element. The pressing tool is closed in a secondary direction perpendicular to the main direction until surfaces of the pressing tool lie against surfaces of the at least one end region, and wedge-like limbs of a drive element of the pressing tool engage wedge-like dies of the pressing tool. The pressing tool is closed further in the secondary direction, subjecting the profile blank to plastic deformation so as to reduce or eliminate the bending of the end region.

An extrusion apparatus includes an extruder, a run-out table that supports an extruded material that has been extruded from the extruder, a feed roller and a pulling roller that are provided at a given interval so as to be able to come in rolling contact with the extruded material that is situated on the run-out table, and a cooling section that cools the extruded material between the feed roller and the pulling roller, wherein the feed roller and the pulling roller apply a tensile force to the extruded material while the extruded material advances from the feed roller to the pulling roller.

The invention for working extruded profile sections with respect to the outer contours thereof by way of hot shaping and/or hot stamping and/or cutting operations and/or punching operations comprises the following method steps: inserting the profile sections (1) heated to a temperature in the range of 250 to 450 C. into a two-part shaping tool (2) preheated to a temperature of 300 to 600 C.; and applying pressure to the shaping tool (2) by way of one or more pressing cylinders (3) of a press (4). The device for carrying out the method comprises a press (4) and a shaping tool, wherein the shaping tool (2) is formed of two tool halves I, II, which are displaceable with respect to each other, and between which the profile section (1) is inserted.

An extruded material includes a peripheral wall having a closed loop-shaped cross-section and defining a hollow, and a middle rib connected to an inner peripheral surface of the peripheral wall and dividing the hollow. The extruded material is provided with a corrected portion set at a predetermined portion in a longitudinal direction and subjected to correction processing, and an uncorrected portion not subjected to the correction processing. The peripheral wall is expanded outward with respect to an original shape of the uncorrected portion in the corrected portion. While the middle rib is curved with respect to an imaginary straight line connecting connecting portions connected with the peripheral wall at both end portions of the middle rib in the uncorrected portion, the middle rib has a smaller degree of curvature than the original shape of the uncorrected portion in the corrected portion.

An + titanium alloy shape includes an acicular microstructure, wherein a 0.2% proof stress is 830 MPa or more, an elongation is 10% or more, a fatigue strength is 450 MPa or more, an area fraction of voids is 1.010.sup.5 % or less, a twist angle from one end to the other end is within 3.0, and a warpage height (mm)/total length (m) is within 2.17.
