Verfahren zur Herstellung einer montagegerechten Anbringungsstelle an einem Hohlprofil

摘要

The component is shaped by internal pressure to accommodate the mounting component. With the internal pressure in the profiled component less than that needed for shaping, the mounting position (10) is rough-shaped using a punch (5). The latter is then left inside the indented portion while high fluidic pressure is generated inside the profiled component (6), causing the walls (13) of the indented portion to press against the punch external surface. Internal pressure is then released and the punch is extracted, leaving a trough-shaped indentation free to form the mounting position.
