Abstract

Nach der Herstellung eines Innenhochdruckumformbauteils (4) wird bei im Innenhochdruckumformwerkzeug (2) verbleibenden Innenhochdruckumformbauteil (4) ein Verbindungs- bzw. Befestigungselement (6) in das Innenhochdruckumformbauteil (4) eingestanzt und anschließend wird das Verbindungs- bzw. Befestigungselement (6) plastisch verformt, so dass es formschlüssig mit dem Innenhochdruckumformbauteil (4) verbunden ist.

Figure 00000001
After the production of an internal high-pressure forming component (4), a connecting or fastening element (6) is punched into the internal high-pressure forming component (4) in the internal high-pressure forming component (4) remaining in the internal high-pressure forming tool (2), and then the connecting or fastening element (6) is plastically deformed , so that it is positively connected to the internal high-pressure forming component (4).
