摘要 |
<p>Production of a peripherally closed hollow profile comprises exerting a counter force on the blank material in pushing movement using a friction generator arranged in a region (11) of an inner high pressure metal forming tool cut (2). An independent claim is also included for a device for producing a peripherally closed hollow profile. Preferred Features: The friction generator is formed by an exposed edge (17) of an opening (14) in the cut of the metal forming tool (1). The opening is assigned to a guiding bore of a stamp integrated in the metal forming tool.</p> |
