摘要： The present invention relates to an apparatus for fastening a functional element to a section of a workpiece and/or for reshaping a section of the workpiece, said apparatus comprising a support device for supporting the workpiece, wherein the workpiece section has a first surface facing the support device and a second surface facing away from the support device. The support device comprises a first support element having a first workpiece support surface that is associated with the first surface, and a second support element having a second workpiece support surface that faces away from the first workpiece support surface and that is associated with a supporting surface. The first and the second support element are movable relative to one another by means of a spreading device such that the first and the second workpiece support surface can be moved away from one another in an axial direction, in particular wherein the axial direction extends perpendicular to the first and/or second workpiece support surface.

摘要： The present invention relates to a self-punching functional element that is adapted for punching into a workpiece, in particular into a sheet metal part. It comprises a head part forming a flange and having a contact surface for contact with the workpiece; and a punching section that extends away from the head part, in particular from the contact surface, and that is in particular arranged coaxially to a central longitudinal axis of the functional element. The punching section has a peripheral punching edge at its free end for punching through the workpiece and surrounds a cavity in a peripheral direction, said cavity having an opening defined by the punching edge. An inner wall of the punching section facing the cavity has at least one elevated slug securing portion projecting radially inwardly into the cavity, in particular wherein the elevated portion has the form of a rib extending in an axial direction.

摘要： A self-piercing rivet element is provided with a body part having a thread cylinder and with a hollow rivet section to be pressed into an as yet unpierced component. In this arrangement, the rivet section is designed to be at least regionally dilatable by means of a die button and tapers in the direction of the central longitudinal axis and away from the body part. The hollow rivet section has, in the region of the transition to the body part, a diameter, which is larger than the outer diameter of the thread cylinder. Furthermore, the rivet section has a closed peripheral wall and an opening at its free end which corresponds at least substantially in diameter to the core diameter of the thread cylinder. Furthermore a component assembly, a method for the manufacture of the component assembly and the die button are claimed.

摘要： A functional element having a section that has a flange, that projects away from a side of the flange, and is adapted for an aperture-free punching into a sheet metal part and having a shaft part that projects away from a side of the flange opposite the first side, that satisfies a function and that is provided with a longitudinal axis. The flange and the section are arranged at least substantially coaxially to the shaft part. The section is formed as a hollow cylinder that has notches extending in parallel with the longitudinal direction at at least one of its outer jacket surface and its inner jacket surface. The section has a diverging frustoconical shape that runs out at least substantially at the free end at the inner side of the section in the region of its free end and that serves for the widening of the section on the punching in the sheet metal part. A component assembly and a method of producing the latter is also claimed.
