Definitions

  • the invention relates to a method for setting blind rivets provided with cylindrical, continuous cavities, preferably for connecting construction parts which are only accessible from one side and provided with mutually aligned bores, the BH rivet being placed on a rivet mandrel with a thickened end, the diameter of which is at least one dimension larger than the diameter of the rivet cavity is placed in such a way that the rivet head lies on the side facing away from the thickened end, then the rivet together with the rivet mandrel is inserted into the mutually aligned bores of the structural parts until the rivet head rests on the surface of the outer structural part, then the rivet head is supported by a hold-down device and finally the rivet mandrel is moved against the pressure direction of the hold-down device to expand the rivet end projecting through the bores, and a device for carrying out this method.
  • a blind rivet with an inserted mandrel is used.
  • the thickened end of the rivet mandrel lies immediately in front of the free end of the rivet to be widened and the mandrel is provided with a predetermined breaking point at a distance from the thickened end.
  • the mandrel protrudes a little from the rivet cavity.
  • the blind rivet is set with the aid of hand riveting pliers or a compressed air-operated riveting device, in that the holding-down device is pressed onto the head of the rivet used and the rivet mandrel is subjected to a tensile force in the direction out of the rivet cavity.
  • the free end of the rivet is widened and after the widening process has been completed, the rivet mandrel tears off at the predetermined breaking point. While the part of the rivet mandrel provided with the thickened end remains in the widened end of the blind rivet or falls off inwards, the part of the rivet mandrel seated in the riveting device is removed and discarded.
  • the invention has for its object to prevent the BHndnlet snake of the type mentioned while retaining all the advantages in that the auxiliary rivet mandrels present in each rivet are dispensed with and the riveting process can thereby be simplified and cheaper. According to the invention this object is achieved in that the thickened end of the rivet mandrel is reduced in diameter after sufficient expansion of the free rivet end until it fits through the rivet cavity, and that the rivet mandrel is then pulled out of the cylindrical rivet cavity on the head side of the rivet and for the next setting process is reused.
  • the blind rivet blanks can be delivered as simple hollow rivets without a lost rivet mandrel needing to be contained in each rivet blank.
  • Another advantage of the method according to the invention is that the degree of expansion of the rivet end can be controlled. While in the known riveting method a given tensile force had to be exerted on the lost mandrel in order to separate it in its predetermined breaking point, the tensile force can be varied depending on the application when using the method according to the invention, because the loosening of the rivet mandrel can be done at any time by reducing the cross section of the mandrel end respectively. For example, by prematurely interrupting the expansion process, relatively loose rivets can also be carried out, which can be used, for example, as hinge points.
  • the method according to the invention is also particularly simple to carry out and even inexperienced People easy to do.
  • the blind rivets can be placed individually on the mandrel, directly on the end of the work, because this can be reduced in diameter to push on the respective rivet.
  • the device for carrying out the method according to the invention is a device with a rivet mandrel with a thickened end, the diameter of which is at least one dimension larger than the diameter of the cylindrical rivet cavity, a hold-down device with an acidic bore in which the rivet mandrel is axially displaceably guided, and a pulling device for moving the mandrel in the direction out of the cavity of the rivet.
  • the device according to the invention is characterized in that the rivet mandrel is formed from at least two flexible tongues which extend in the longitudinal direction of the mandrel and which, at their free ends, have projections forming the thickened end on their radially outwardly facing sides, that between the tongues there is also a longitudinal mandrel direction extending support element is provided, which is displaceable in the longitudinal direction of the mandrel relative to the tongues, and that the support element can be positioned at least for widening the rivet end in a position advanced relative to the tongues, in which it is also between the free ends provided with the projections the tongues are located, and for pulling the mandrel out of the rivet cavity after the rivet end has been widened into a retracted position in which the tongue ends provided with the projections can be pivoted relative to one another.
  • the rivet mandrel can have two tongues, the cross section of which has the shape of a segment of a circle, while rend the support element has a flat, rectangular cross section, the width of which corresponds approximately to that of the tongues.
  • more than two tongues can also be provided, the support element being a polygon corresponding to the number of tongues.
  • the hold-down device and the rivet mandrel are preferably parts of rivet pliers, the hold-down device being fixedly attached to the working end of the pliers housing and the tongues on the one hand and the support element on the other hand being operable independently of one another.
  • the movements of the tongues and the support element can be coordinated with one another depending on the setting process. In this way it is possible to adjust the tightness of the rivet precisely.
  • the tongues and the support element are expediently pretensioned into their most extended position from the hold-down device by means of a common spring device and the rivet mandrel parts can be displaced via a common drive mechanism, the rivet mandrel parts being able to be uncoupled individually from the drive mechanism depending on the setting process.
  • a drivable piston which is guided in the axial direction of the rivet mandrel and is mounted in a guide channel formed in the pliers housing can be provided as the drive mechanism. Furthermore, a piston carrying the tongues can be arranged on the side of the drive piston pointing towards the working end of the rivet pliers, while a driving piston is additionally provided on the side of the working piston facing away from the working end.
  • the support expediently extends through the central bores provided in all three pistons, protrudes through the driving piston and bears with a head on the side of the driving piston facing away from the working end.
  • these three pistons can optionally be coupled with one another in order to carry out the setting process optimally.
  • the driving piston can be locked in the area of the guide channel facing away from the working end, while the drive piston is moved with the tongue piston towards the working end of the device, so that the tongue ends can bend against each other, which thickens them End reduced in cross section so that the rivet mandrel fits through the rivet cavity.
  • all three pistons can be coupled to one another and can be moved in the direction away from the working end of the device.
  • the piston carrying the tongues can be uncoupled from the working piston.
  • the tongue piston can be coupled to the drive piston again.
  • the uncoupling and subsequent recoupling of the tongue piston to the drive piston can preferably take place as a function of the position of the drive piston and can be selectively adjustable. This measure makes the effective expansion of the rivet mandrel and therefore the tightness of the rivet seat.

Abstract

Les rivets borgnes (1) son posés en les plaçant sur un poinçon à river (2) à extrémité élargie dont le diamètre est supérieur à celui du trou (8) du rivet de sorte que la tête (9) du rivet se trouve du côté opposé à l'extrémité élargie. Après celà, on introduit le rivet (1) avec le poinçon à river (2) dans les trous (13, 14) des composants (15, 16). Ensuite, la tête (9) du rivet est maintenue par un porte-rivet (3) et finalement le poinçon à river (2) est refoulé dans le sens opposé à celui dans lequel le porte-rivet (3) est appuyé, afin d'élargir l'extrémité (12) du rivet qui sort par l'extrémité des trous (13, 14). Pour pouvoir réutiliser le poinçon à river (2) et par là simplifier et rendre moins cher le rivetage, on réduit le diamètre de l'extrémité élargie du poinçon à river (2), une fois que l'extrémité libre (12) du rivet a été suffisamment élargie, jusqu'à ce qu'elle passe par le trou (8) du rivet. Ensuite, le poinçon à river (2) se trouvant du côté tête (9) de rivet (1) est retiré du trou (8) du rivet et réutilisé pour l'opération de rivetage suivant. Le procédé est réalisé à 'aide d'un ensemble à river (18) qui incorpore le poinçon à river (2).
