Definitions

  • the invention relates to a method for setting blind rivets provided with cylindrical, continuous cavities, preferably for connecting structural parts which are only accessible from one side and provided with mutually aligned bores, and a device for carrying out this method.
  • Blind riveting methods are used for riveting structures that are only accessible from one side, for example in body and small container construction, in double-shell construction and the like.
  • a hand rivet pliers with a rivet mandrel for expanding eyelets is known.
  • the rivet mandrel is slotted in two perpendicular planes intersecting, so that four approximately quarter-circular mandrel parts are created.
  • a cross-shaped support element is used to fix the spreading position.
  • the rivet mandrel can be actuated with the aid of a pliers mechanism and a double and counter-rotating toggle lever which can be driven thereby.
  • the support element must be pushed back and forth separately by hand.
  • the head of the rivet mandrel is clamped in the widened area of the eyelet.
  • the central cross-shaped support element cannot be pulled back by hand. Rather, it is necessary that the rivet mandrel is first pushed back a bit in order to reduce the contact pressure of the fingers on the support element so that the support element can be moved back by hand with less force.
  • the invention has for its object to provide a riveting process that is easier and faster to perform.
  • the blind rivet is first placed on the mandrel. In this position, the blind rivet can be inserted very easily into the holes and fixed by appropriate handling of the rivet mandrel.
  • the rivet mandrel When the respective hollow rivet is set, the rivet mandrel can be pulled out of the rivet cavity immediately after the hollow rivet has expanded, as a result of which the method can be considerably accelerated.
  • the rivets can be placed individually on the rivet mandrel, directly on the end of the work, which can be reduced in diameter to push on the respective rivet.
  • the tongues of the rivet mandrel expediently have the shape of a circular segment in cross section, while the support element has a flat, rectangular cross section, the width of which corresponds approximately to that of the tongues.
  • the support element With a larger rivet diameter, more than two tongues can also be provided, the support element being a polygon according to the number of tongues.

  • 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 biased 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 by means of 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 housing of the riveting device can be provided as the drive mechanism.

  • 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 far 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.

Through this measure, the effective expansion of the rivet mandrel and thus the tightness of the rivet seat.
  • one pliers leg can be rigidly connected to the pliers housing, while the other pliers leg, forming a two-armed lever, is articulated on the pliers housing, the short lever having a fork-shaped end in a driving recess engages the drive piston.

First of all, however, the functional sequence of the blind riveting method will first be explained with reference to FIGS. 1 to 8:
  • a simple blind rivet 1 is used for the method, which has a cylindrical, continuous cavity 8 and is provided at one end with a flange-like head 9 which projects radially from the tubular rivet shaft 10.
  • the blind rivet can, for example, consist of an easily deformable aluminum alloy, but other materials are also possible depending on the application.

  • the projections 7 rest against the end 12 of the blind rivet 1 that is to be widened and deform it to the bead 17 shown in FIG. 5.
  • the support element 6 becomes one piece pulled into the hold-down device 3 so that the free ends of the tongues 4 and 5 can be pivoted towards one another again and the thickened end of the rivet mandrel 2 can be reduced in diameter. Then the rivet mandrel 2 is pulled through the rivet cavity against the hold-down device and the riveting process is ended.

  • This construction divides the upper short lever arm 28 of the hand lever 22, which has the advantage that the pivot angle of the hand lever 22 does not need to be excessively large, but on the other hand a large power transmission ratio is available, at least for a short time, for operations to which greater force can be applied.
  • the two housing parts 19 and 20 are essentially cylindrical, the right housing part 20 being inserted into the left housing part 19 on one side.

  • the coupling between the two inclined surfaces of the locking lug 44 and the step-shaped shoulder 43 is maintained in that the driving lever 37 cannot deflect upwards, since it strikes the inner wall of the outer housing 19.
  • the support element 6 and the two tongues 4 and 5 shift evenly to the right again. As shown in FIG. 7, this movement is used to pull the rivet mandrel 2 out of the rivet 1 that has been set. Since the support element 6 is in the retracted position, the two tongues 4 and 5 can be bent inwards and the thickened end can be pulled through the rivet cavity.
  • the hold-down bracket 45 is arranged to be adjustable.
  • the hold-down bracket 45 is arranged axially displaceably in the recess 41 of the housing part 20 and can be displaced with the aid of an adjusting screw 47, which is accessible from the outside of the housing.

  • a compression spring 50 which is supported on the housing part 20, ensures that the latch 49 remains in its locking position.
  • the drive piston 30 is moved to the left in the drawing, while the driving piston 32 remains in its latched position.
  • a tension spring 55 which is stretched between the drive piston 30 and the tongue piston 31, pulls the tongue piston 31 onto the drive piston 30 until it comes to bear against it.
  • the driving lever 30, which is prestressed in the direction of the coupling position with the aid of a compression spring 51, then snaps back into its first coupling position, in which the step-shaped shoulder 42, which is closer to the pin joint 38, engages via the locking lug 44.
  • An additional tension spring 54 which is stretched between the drive piston 30 and the working end of the housing, exerts a biasing force directed to the left in the drawing via the drive piston on the tongue piston and thereby on the tongues 4 and 5, so that it is ensured that when inserting a hollow rivet 1 on the rivet mandrel 2 it does not move back.

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).
