摘要: The self-penetrating fastening device proposed consists of a rivet (3), acted on by a punch (13), and a die (15), the rivet consisting of a head (4) and a shank (6) with a central cavity (8) whose open end partly penetrates a metal sheet (1) in which it is held. At the end of the rivet shank (6) remote from the rivet head (4), the cavity (8) is essentially conical in shape, the angle of the aperture being &agr;. In addition, the transition zone between the rivet shaft (6) and the underneath (11) of the rivet head (4) is essentially rounded (R1). A rivet joint produced using this device is sufficiently strong to meet severe requirements, and the surface of the metal sheet in the region of the rivet is not affected by the perforation process.

摘要: A method of riveting comprises inserting a self-piercing rivet into sheet material without full penetration such that the deformed end of the rivet remains encapsulated by an upset annulus of the sheet material. The sheet material is clamped with a substantial force during the riveting operation in the region around the rivet insertion location. The clamping force is maintained constant throughout at least the major part of the riveting operation and has a magnitude of up to 1.5 tonnes. A riveting machine for carrying out the method comprises a punch, means for feeding rivets successively to the punch for insertion into sheet material to be riveted, a die aligned with the punch for deforming the rivet inserted thereby, and clamping means for clamping the sheet material with a substantial force during the riveting operation in the region around the rivet insertion location.

摘要: A rivet capable of self-piercing at least one sheet of material and becoming embedded in one of such sheets, generally consisting of a head section and a shank section formed integrally with the head section, wherein the head section includes an upwardly and outwardly curved side wall surface extending from the shank section to an upper portion of the head section, and the shank section includes a recess in a lower end thereof, with the lower end of the shank section having a peripheral cutting edge sufficient to penetrate such material.
