Abstract

In a method of making a tubular support bar for a dashboard support, a sheet metal blank is placed in a first forming tool and pressed in a first shaping step by a ram into a U-shaped cavity of a first bottom die to form a U-shaped member. While remaining in the first bottom die, the U-shaped member is provided with connecting elements in the form of weld nuts by a automated placement device. Subsequently, the U-shaped member is transferred to a second forming tool and undergoes a second shaping step between a top die and a second bottom die to form a slotted tube. The longitudinal edges of the slotted tube are then joined together to form the support bar.
