Verfahren zur Bildung eines Vorformlings für die Innenhochdruckverformung. |
摘要 |
To form a body, a preform is produced by welding together two essentially flat sheet-metal blanks at their margins. This preform is then deformed in a mold by internal high-pressure forming to produce the desired body. In this way, complex metal bodies can easily be formed. |
