There is described an expanding blind rivet assembly having a flange (3) provided with an undercut surface facing the rivet shank.
A particularly low-cost connection to contact parts is possible when the connection part (6) has a rivet shank (8a) on the side opposite from the welded seam (9).
The aperture in the second element may form a cylindrical surface that bears against the rivet shaft without the use of a washer between the cylindrical surface and the rivet shaft.
A flapper valve is then mounted on the rivet shaft to cover the valve orifice, and the rivet shaft is deformed to retain the flapper valve in place.
To this end, the transition (8) from the outer diameter (D2) of the rivet shaft (6) to that of the rivet head (4) is configured as a series of discrete sections (22), thereby forming especially a polygonal geometry of the zone below the head.
The rivet shaft (3) also comprises at least two grooves (9) on the outside, these grooves extending from the front shaft (7) in the direction of the rear end (18), parallel to the central axis (6).
The width of the slots is smaller than the diameter of the rivet pin.
The mounting (5) contains a cylindrical passage for the rivet mandrel (2).
The invention relates to a blind rivet assembly (1) provided with a blind rivet comprising: a sleeve (2) having a shaft (3) and a factory head (4); and a rivet mandrel (5).
The invention relates to a blind rivet assembly (1) provided with a blind rivet (2) comprising: a sleeve (3) having a shaft (4) and a factory head (5); and a rivet mandrel (6).
The width of the slots is less than the diameter of the passage for the rivet mandrel.
To this end the mandrel (2) and the mandrel head (8) are designed as parts that are produced separately and joined together.
The rivet rod (41) extends through the container wall and is anchored inside the unit (20).
The rivet pin has been obtained in a separate production process, for example by injection-moulding.
The apparatus includes drivable means (16, 86) such as a mandrel engaging wheel for engaging and pulling the mandrel (88) and means for pressing (20, 21, 92, 93) the mandrel (88) against the drivable means (16, 86).
The main body part includes a pin or shaft of a rivet spaced adjacent to the valve orifice.
By means of the ribbing, a tool is able to engage with a form fit on the rivet mandrel.
As a result, said part of the traction device then remains blocked in position whilst the rivet pin (1) continues to advance.
Said holding element (5) comprises a central, cylindrical passage, the diameter thereof being slighter bigger than the diameter of the rivet pin.
The method according to the invention is characterized in that the riveted fastening takes place by means of at least one prefabricated rivet pin (9) made of thermoplastic material.
At least two, preferably three clamping jaws (10), which are introduced into radial slots (7) so that they can be displaced in a radial and axial manner, interact on the rivet pins.
