Abstract:
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.
