Abstract
A method and to a system for producing open or closed annular structural components made of light metal and alloys thereof, preferably of magnesium or magnesium alloys, having a two-dimensional or three-dimensional structure by means of extrusion, wherein the extruded profile exiting the die of the extrusion press is formed into a helical shape by way of one or more guide tools, and more particularly such that the ends of the helical shape are separated from the extruded strand in the region of the overlap and formed into a two-dimensional or three-dimensional structural component in a shaping device.
Claims9
A method for producing a structural component, comprising:
- extruding a metal through a die of an extrusion press to provide an extruded profile in a form of a continuous strip;
- shaping the continuous strip as it exits the die into a nonplanar configuration having a polygonal shape with corner regions, the continuous strip in the nonplanar configuration having two overlapping ends arranged in separate planes;
- separating a predetermined length of the extruded profile from the continuous strip, the length being predetermined such that the two ends overlap sufficiently to provide a site for inseparably connecting the two ends;
- and
- forming the nonplanar configuration into an endless configuration constituting the structural component.
A system for producing a structural component, the system comprising a production line comprising, in the following sequence:
- a site for storage of ingots of a metal;
- a furnace configured to receive and heat the ingots;
- an extrusion press having a die, the extrusion press being configured to receive the heated ingots from the furnace and extrude a profile in form of a continuous strip;
- a guide tool configured to shape the continuous strip as it exits the die into a nonplanar configuration in which the continuous strip has two overlapping ends arranged in separate planes, the guide tool comprising at least two parts which are displaceable relative to each other;
- a separating device configured to separate a predetermined length of the profile from the continuous strip;
- and
- a device for inseparable connecting the two overlapping ends of the separated profile at the overlap to provide the structural component.
