摘要： Blind rivet arrangement (10) for producing a blind rivet joint (64), said blind rivet arrangement having a rivet body (12) and having a mandrel (14), wherein the rivet body (12) comprises a rivet head (20), a rivet shank (26) and a continuous rivet bore (30), wherein the mandrel (14) comprises a mandrel head (32) and a mandrel shank (36) which is inserted in the rivet bore, wherein the rivet bore (30) comprises a first bore cross section (D
1 ) in the region of an end of the rivet shank (26) which is opposite the rivet head (20), wherein the mandrel shank(36) comprises a first shank cross section (D
2 ) in a first mandrel region (B
1 ) adjacent to the mandrel head (32), and wherein the first shank cross section (D
2 ) is adapted to the first bore cross section (D
1 ). In this case, in a second mandrel region (B
2 ) which projects out of the rivet bore (30), the mandrel shank (36) comprises a second shank cross section (D
3 ) which is smaller than the first shank cross section (D
2 ).-

摘要： In a method for fastening a rivet element (1) to at least one workpiece (W) a rivet element (1) is used that has has a hollow shank (2), a punch head (5) at one end of the shank (2), a flange (8) at a distance from the punch head (5), and a deformation region (9) between the flange (8) and the punch head (5). By means of a cylindrical mandrel (15) of a fastening device (20), the punch head (5) of the rivet element (1) is pressed through the workpiece supported on a first dolly (12), thereby forming a rivet hole. Subsequently, by means of a riveting die (17) directed toward the punch head (5), the deformation region (9) of the shank (2) is formed into a closure flange (18) contacting the workpiece (W), wherein the flange of the rivet element (1) is supported on a second dolly (14).

摘要： Blind rivet (10) having a rivet sleeve (12) and a pin (14), the rivet sleeve (12) having a sleeve head (16) for contact with a visible-side workpiece surface (53) and a sleeve shank (18) and a through hole (24), through which the pin (14) is guided, the pin (14) having a blind-side pin head (26) for contact in the region of a blind-side end (20) of the sleeve shank (18), and the sleeve shank (18) having a first forming section (34) and a second forming section (36) which is arranged axially spaced apart from the first forming section (34) and closer to the sleeve head (16), a first intermediate section (38) being formed between the first and the second forming section, which first intermediate section (38), during setting of the blind rivet, can form a first blind head (56) which can be formed at axially different points in order to set up different clamping thicknesses (K). Here, the sleeve shank (18) has a third forming section (40) which is arranged axially spaced apart from the second forming section (36) and closer to the sleeve head (16), a second intermediate section (42) being formed between the second and the third forming section in such a way that, during setting of the blind rivet for setting up relatively great clamping thicknesses (K
MAX ), the second intermediate section is arranged axially between the first blind head (56), which is formed by the first intermediate section (38), and the sleeve head (16) and, during setting of the blind rivet for setting up relatively small clamping thicknesses (K
MIN ), forms a second blind head (58).摘要翻译： 一种具有铆钉套筒和销钉的盲铆钉，所述铆钉套筒具有用于与可见侧工件表面接触的套筒头和套筒柄和通孔，所述销通过所述通孔被引导，所述销具有盲侧 销头用于在套筒柄的盲侧端部的区域中接触，并且套筒柄具有第一成形部分和第二成形部分，该第一成形部分和第二成形部分布置成与第一成形部分轴向间隔开并且更靠近套筒头部， 第一中间部分形成在第一和第二成形部分之间，该第一中间部分在设置盲铆钉期间可以形成可以在轴向不同点处形成的第一盲头，以便设定不同的夹紧厚度。

摘要： Verfahren zum Herstellen einer Blindniete (32), Befestigungsanordnung (68) und Prägewerkzeug (44) zum Herstellen eines Blindniets (32) mit:
- einer Niethülse (10) mit einem Hülsenkopf und einem Hülsenschaft, wobei der Hülsenschaft einen an den Hülsenkopf angrenzenden ersten Abschnitt und einen sich daran anschließenden und bis zum Fußende erstreckenden zweiten Abschnitt aufweist, und
- einem Nietdorn (30) mit einem Dornschaft, wobei der Dornschaft in einer Längsbohrung der Niethülse angeordnet ist,
wobei der zweite Abschnitt dazu ausgebildet ist, sich bei einem Setzvorgang zumindest teilweise zu einem Blindkopf zu verformen, und wobei der erste Abschnitt (24) einen gegenüber dem zweiten Abschnitt (26) radial nach außen versetzte Außenfläche aufweist, so dass eine Schulter (28) zwischen den Außenflächen des ersten und zweiten Abschnitts (24, 26) angeordnet ist, und wobei der erste Abschnitt am Außenumfang des Hülsenschaftes zur Erhöhung seiner Festigkeit plastisch verformt ist.-
