In a method for manufacturing structural components from an extruded section, especially consisting of Al, Mg or their alloys, which after its exit from the die of the extrusion press, is guided by one or a plurality of guide tools for the purpose of forming it as a straight or arc-shaped (rounded)
In a method for manufacturing structural components from an extruded section, especially consisting of Al, Mg or their alloys, which after its exit from the die of the extrusion press, is guided by one or a plurality of guide tools for the purpose of forming it as a straight or arc-shaped (rounded) section, an end section is separated by a separating tool and in the hot state, is fed by means of gripping tools to a hot-forming process and successively to one or a plurality of processing stations.

1. A method for manufacturing structural components from an extruded section consisting of Al, Mg or their alloys, comprising the steps of:after an exit of the extruded section from a die of an extrusion press, guiding said extruded section by one or a plurality of guide tools for the purpose of forming said extruded section into a straight or arc-shaped section, separating an end section of said extruded section by a separating tool in a hot state and feeding said end section by means of gripping tools to a hot-forming process and successively to one or a plurality of processing stations, wherein before feeding to the hot-forming process or processing stations, the processing temperature is adjusted to the optimum process temperature by cooling the workpiece, wherein the temperature for the hot-forming process is between 180° C. and 400° C. for the manufacture of Mg structural components, and wherein the temperature for the hot-forming process is between 300° C. and 600° C. for the manufacture of Al structural components. 2. The method according to claim 1 wherein the manufacturing process is completely or partly enveloped by protective gas.3. The method according to claim 1, further comprising the steps of extruding an Aluminum workpiece and extruding a Magnesium workpiece and bringing said workpieces together by means of friction stir welding or adhesion.4. The method according to claim 1, wherein the hot-forming process is configured as internal high-pressure forming, forging or embossing.5. The method according to claim 1, wherein the hot-forming process comprises a calibration step.6. The method according to claim 1, wherein for the manufacture of Mg structural components the hot-forming temperature is between 225° C. to 280° C.7. The method according to claim 1, wherein for the manufacture of Al structural components the hot-forming temperature is between 400° C. to 520° C.8. The method according to claim 1, wherein the hot-forming process is followed by artificial aging and then by mechanical processing, wherein the workpiece is cooled in a preceding cooling zone before the artificial aging.9. The method according to claim 1, wherein the workpiece is transferred between the processing stations by gripping tools in the fashion of handling robots which follow the extruded section.10. The method according to claim 1, wherein the guiding and separating tools are each constructed as guiding and separating robots.11. The method according to claim 10, wherein the guiding robots are each supported in a spatially fixed position outside the extruded section and are provided with a guiding device which is moveable in a plane perpendicular to the pressing plane and/or is rotatable its axis of rotation.12. The method according to claim 10, wherein the separating robots are each connected firmly to the extruded section in the range of a separating point during the separating step.13. The method according to claim 1, wherein at least one guide tool is path-controlled depending on a pressing path and on a curvature trend of the extruded section.14. The method according to claim 13, wherein a pressing distance is measured directly on the workpiece by means of a sensor device attached to the guide tool.15. The method according to claim 14, wherein the extruded section is guided by several reversibly controlled guiding tools.16. The method according to claim 1, wherein the cycle times with which the process and processing steps follow one another are substantially matched to the extrusion speed.17. The method according to claim 15, wherein the extruded section is deformed by at least one guiding tool wherein at least two handling tools can be alternately returned to the beginning and support the emerging extruded section.
