METHOD, DEVICE AND AUXILIARY JOINING ELEMENT FOR JOINING AT LEAST TWO PARTS |
摘要 |
Two components are held in at least partially overlapping relation to each other between a hold-down device and an essentially flat lower tool and then are joined together by pressing an auxiliary joining element into one of the components a sufficient distance to plastically deform the components in a manner that positively joins the two components together. A tool with an optional wobbling movement and/or an optional variable force is used to press the auxiliary joining element into the first component. The magnitude of force applied by the hold-down device affects the direction of plastic flow of the material of the components in relation to the flat lower tool. |
