    摘要: A process for extruding a section or the like from a billet, in which a billet is introduced into the bore of a container and, by an extrusion stem, is fed in the direction of extrusion into a shape-forming cross-sectional opening in a die. The billet material is pressed into a central inlet in the die and the resultant ductile mass fed outwards at an angle to the direction of extrusion through a plurality of channels to the shape-forming cross-section. The main load is applied by the extrusion force acting outside the central inlet and the shape-forming region and is preferably diverted outside the shape-forming region to the supporting die parts.

    摘要: A process allows the production of composite sections made of at least two component parts such as conductor rails or the like having a beam-like section with a facing in the form of a conductive metal strip. The process makes use of an extrusion die whereby at least one of the components of the composite section is fed to the die by means of frictional force on a face which moves continuously towards the die.

    摘要: A process for extruding a metal billet, in particular a light metal billet in an extrusion container, into the form of a hollow section through a shape-giving orifice in a die having a mandrel which determines the inner contour of the hollow section, and a device with stem for extruding should be designed such that it is possible to produce flanged tubes with integral flange in one piece. This object is achieved by way of the invention in that in the extrusion of the hollow section an integral flange is produced, preferably at the end of the extrusion stroke. In the extrusion press suitable for this purpose a shaping recess is provided, with respect to the extrusion direction, immediately before the orifice of the die, the radial dimension of which is greater than the width of the die orifice. As such it should be possible to separate the die radial to the extrusion direction into at least two parts.

    摘要: 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 movable 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.

A shaping recess is provided, with respect to the extrusion direction x, immediately in front of the shape-giving orifice of the die, the radial dimension of which recess is greater than the width of the shape-giving orifice. The shaping recess is provided either in the face of the die directed towards the extrusion stem or in the face of the extrusion stem directed towards face of the die.
