VERFAHREN ZUR HERSTELLUNG EINES ROHRARTIGEN TEILES MIT DURCH HYDRO-UMFORMEN GEFORMTEN VERBINDUNGSTEIL

摘要

A method for forming a hollow part ( 18 ) that allows the use of hydroforming in cases where the part interconnects between sections having extreme variations in cross-section. A complete hollow part ( 18 ) is formed by joining a hydroformed hollow section with hollow sections. A method for securing a fastener sleeve ( 102 ) insert in a pre-fabricated hollow part ( 100 ) is also provided. In this method, the hollow part ( 100 ) is deformed slightly to form flanges ( 108 ) that secure the insert ( 102 ) in the part. Once the insert ( 102 ) is secure in the hollow part, fasteners can be applied to the part without collapsing it.
