Element, method of attaching the element to a plate-like component, component assembly and die button |
摘要 |
An element, for example an element with a hollow body or a bolt element, in particular a nut element, for attachment to a plate-like component, has a ring-shaped recess or annular groove present at an end face of the element facing the component within a raised ring-shaped contact surface. At least one undercut is preferably provided in a side wall of the recess, and also features radial recesses and noses which extend into the ring recess providing security against rotation. A cylindrical punch section or pilot concentric to the central longitudinal axis of the element projects at the said end face within the ring-shaped recess and the outer boundary wall of the cylindrical punch section preferably has ring-shaped undercut. A material supply is formed at or adjacent to the free end face of the cylindrical punch section and is displaceable at least locally by means of a die button on insertion of the element into the ring-shaped recess in order to capture or clamp material of the component which has previously been deformed by the die button into the ring-shaped recess between itself and the base surface of the ring recess. In this way an improved security against rotation, an increased press-out resistance and an improved behavior against alternating loads in operation is achieved.
