Method of internal high pressure forming a bent single or multiple compartment hollow profile |
摘要 |
The deforming tool has a pusher element (21) in the inner arc wall region of the curved blank. At the beginning of the deformation of the inner arc wall region, it provides a counter-force. During the deformation, it is withdrawn from this region so that the inner arc wall region is pressed out towards the withdrawing pusher element. |
