A device and method for designing lightweight, strong, material efficient, extruded and pultruded profiles, profile segments and surfaces produced in profile production with rotating dies creating superior resistance to compression, bending and buckling, higher energy absorption and right strength in the right place, by: varying the thickness along and across the direction of extrusion, making reinforcing patterns varying the profile thickness, and in some cases varying angles and patterns which increases the profile segments/surface resistance against compression, bending and buckling relative to the amount of material used and resulting in the manufacturing of optimized beams and surfaces that have superior properties in terms of strength/weight, stiffness/weight ratio, mechanical energy absorption/weight unit, deformation and natural frequency, thermal transfer capacity, the breaking of the laminar flow, increased/optimized surface for chemical and/or electrochemical reaction etc.

Conventionally, in industries, different complex profiles (e.g., objects) are extruded and cut to required lengths for handling these profiles. This requires moving profiles from one location to another and placing them together with other similar or identical profiles which is currently a manual process. Present disclosure provides an apparatus for re-orientation of profiles for easy pick and place of these profiles from one location to another location. The apparatus includes actuator arm assemblies that are actuated for movement in upward and downward direction, wherein actuated rollers are trigged to move upward/downward directions accordingly. Profile is placed in initial position on an endless re-orienting belt above the surface of actuator arm assemblies wherein each actuator arm assembly is actuated to move the profile from one sub-region to another sub-region until the profile attains a desired orientation for pick and place of the re-oriented profile to desired location with required angle.

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.

The present invention discloses a forward and backward extrusion composite forming method using a mould having an open inner cavity, including the following steps: (1) the structural design and assembly of the forward and backward extrusion composite mould having the open inner cavity; (2) the preparation of the initial billet; and (3) forward and backward extrusion composite forming. The present invention can greatly improve the length-diameter ratio of the blind hole and is widely used in alloy steel, aluminum alloy, magnesium alloy, copper alloy and other components.

A method is used to manufacture an article using a machine having a fixed base and a press structure movable toward the fixed base. The machine also includes a die assembly and a container both coupled to the fixed base. The machine further includes a mandrel assembly comprising a rotatable platform coupled to the press structure and having a first platform mandrel aligned with the die assembly and a second platform mandrel aligned with the container. The method includes the steps of placing a first starting component into the die assembly, pressing the first starting component to form the article, moving the second platform mandrel into the container simultaneously with the step of pressing the first starting component, and rotating the rotatable platform to align the second platform mandrel with the die assembly and to align the first platform mandrel with the container.

A puller apparatus has a path through which an extrusion travels downstream from an outlet of an extruder and upper and lower extrusion puller members that define a portion of the path. At least one of the extrusion puller members is a drive member to provide forward motion to an extrusion. A mounting arm is moveably mounted to the puller apparatus at a mounting location. The mounting arm has a first portion on one side of the mounting location and a second portion on an opposed side of the mounting location. The upper extrusion puller member is mounted to the first portion of the mounting arm. The mounting arm is movable from a lowered position in which the upper extrusion puller member is positioned to engage an extrusion in the path and a raised position in which the upper extrusion puller member is spaced upwardly from the lowered position.

A method for producing a lightweight sheet-metal component with varying wall thicknesses includes extruding a lightweight metal to form a profile with a non-planar profile cross section, wherein the wall thicknesses of the profile cross section differ from one another in at least two regions, cutting the profile to length into profile pieces, widening the profile pieces, and forming the flattened profile piece into a three-dimensional shaped sheet-metal component, wherein the sheet-metal component has at least two regions with wall thicknesses that are different from one another.

A device and method enabling industrial continuous pressing, called extrusion of plastically/thermally mouldable substances such as metal, composite metal, plastic, composite or rubber, which is pressed to the profile by a process including a tool fixed member partially predefining the profile shape/cross-section before the profile is finally defined to a cross-section when the material passes rotating dies, which through contact with each other, cancel out main radial forces and the position of which may vary relative to other bearing surfaces or rotary bearing surfaces of the tool with which they define the final shape of the profile. The device and method enable the extrusion of pattern on the inside of hollow profiles and the extrusion of multiple profiles in one tool, because 80-98% of radial bearing forces are eliminated, allowing the installation of rotary dies where not previously possible, and almost unlimited opportunities in increased profile width.

A method is used to manufacture a tube having a hollow interior for housing an axle shaft. The tube is formed in a single machine having a fixed base and a single press structure movable toward the fixed base. The single machine includes first and second die assemblies coupled to the fixed base and first and second mandrels coupled to the single press structure. The method includes the steps of placing a billet into the first die assembly, pressing the billet into the first die assembly with the first mandrel to producing a pre-formed billet, and moving the pre-formed billet from the first die assembly to the second die assembly. THE method further includes the steps of pressing the pre-formed billet into the second die assembly with the second mandrel to elongate the pre-formed billet and form a hollow interior therein to produce an extruded tube.
