Method for manufacturing component i.e. spring link, for chassis of motor car, involves calibrating blank part in attachment region, and performing calibration and punching of blank part in common tool

The method involves forging a molding blank to a blank part, and calibrating the blank part in an attachment region (5). A component is completed by forming mounting holes (21) in the attachment region by punching. Wall thickness in a region of the mounting holes is reduced during calibration and/or...

Beschreibung
Zusammenfassung:	The method involves forging a molding blank to a blank part, and calibrating the blank part in an attachment region (5). A component is completed by forming mounting holes (21) in the attachment region by punching. Wall thickness in a region of the mounting holes is reduced during calibration and/or forging. The calibration and punching of the blank part are performed in a common tool i.e. calibration/punching tool (23). A punching device (13) is integrated in an upper die (7). The blank part and/or the component are subjected to heat treatment. Es wird ein Verfahren zur Herstellung eines Bauteils für ein Kraftfahrzeug mit folgenden Schritten vorgeschlagen: Schmieden eines Rohlings zu einem Rohteil (1), Kalibrieren des Rohteils (1) zumindest in wenigstens einem Anbindungsbereich (5), und Fertigstellen des Bauteils durch Ausbilden einer Befestigungsbohrung (21) in dem Anbindungsbereich durch Stanzen.
