摘要:
A composite section (10) features a base (12) of light-weight metallic material as section component and at least one further profiled section component, in particular a profiled strip (18) of another metallic material which is joined metallically as a surface layer to the base section during an extrusion process. Projecting out of the inner-lying face (21) of the profiled strip (18) and directed at the base (12) is at least one projection and/or an additional element (23) which are/is embedded in the base (12). Each additional element (23) may delimit an undercut space which is filled in an interlocking manner by metallic material of the base (12).

A process for extruding a section or the like body from an ingot is such that an ingot is introduced into a bore of a container and, by means of an extrusion stem, is fed in the direction of extrusion into a shape-giving opening in a die. Before the ingot enters the die opening, it is pushed out of the container by an amount corresponding to the width (t) of a collar whereupon a disk-shaped slice is sheared off the free end of the ingot and removed. The free end of the ingot is then pushed onto the die opening. In order to carry out this process a shearing tool is provided after the end of the container facing the die and a moveable shearing blade positioned over that entrance to the container bore The disk-shaped slice should preferably be sheared away together with a residual butt of the previously extruded ingot which faces away from the die. To that end a shearing tool with two shearing blades is provided and can be moved radially with respect to the longitudinal axis (A) of the container bore.

摘要:
A composite profile comprising an extruded aluminum alloy carrier profile comprising a rail head having a longitudinal axis B, the rail head comprises a surface and two longitudinal edges extending parallel to the longitudinal axis B and a metal channel shaped profile strip comprising a base portion spanning the surface of the rail head and parallel side legs which lie on the longitudinal edges of the head rail, an insert rod is provided on the parallel side legs which lie on the longitudinal edges of the head rail and engage in lateral slots provided in the two longitudinal edges of the rail head, wherein the profile strip is attached to the carrier profile under mechanical pretension by way of a weld seam which contacts the rail head of the extruded aluminum alloy carrier profile.
