Definitions

  • the invention relates to a method according to the preamble of inde pendent claims 1 and 2.
  • a method is, for example US-A-5678970 known.
  • Punch rivets are understood to mean a riveting method in accordance with DIN 8593-5, issued Sept. 2003, in which a full-rivet or half-tubular rivet is driven from a ram through at least two unperforated sheet-like components with the aid of a hold-down device.
  • a die On the side facing away from the stamp a die is arranged, on the one hand forms the abutment for holding down and on the other serves to deform the lower component or the rivet in the lower component, so that a positive connection between the punch rivet and the lower component arises.
  • semi-hollow punch rivet of Halbhohlstanzniet does not emerge from the lower component.
  • the punch riveting tool suitable for this purpose generally consists of a C-shaped frame, wherein on one side a die and on the other side a hydraulically or pneumatically movable punch is provided, which is enclosed by a holding-down device.
  • Such punch rivets are usually attached to robots, which then drive the punch riveter to the attachment point.
  • Such a system for a semi-hollow punch rivet describes, for example, the US-A 5,752,305 ,
  • clamping forces of some 100 N up to 15 kN are referred to as usual, with clamping forces at such a height according to the US patent, a deep-drawing process in the sheets in the punched rivet is to be avoided, which turned out to be in practice but not applicable Has.
  • Object of the present invention is to propose a method for setting punched rivets, while maintaining the known punching rivets, with a reduction of the joining forces is possible.
  • the first alternative according to claim 1 describes a waiting time at a constant clamping force. This can be used for the known determination of the component thicknesses via a displacement measurement of the stamp path.
  • Claims 3 and 4 describe areas for the waiting time and for the clamping force in the connection of two aluminum sheets of conventional configuration, as used in the automotive industry.
  • the clamping force is exerted solely on the punch rivet on the sheets / components to be joined and not - as in practice - on the hold-down.
  • Two sheets to be joined are accurately clamped in a known manner. Then, a punch riveter attached to a robot is moved to the joint.
  • the punch riveter is usually connected to a rivet stock and a rivet feed device.
  • the hold-down is moved down so that it compresses the sheets to be riveted and presses against the arranged on the underside of the component die.
  • the adhesive previously applied to the insides of the sheets to be joined is distributed.
  • clamping forces of 2 to 10 kN are applied via the hold-down device for a period of 0.1 to 2 seconds.
  • the punch moves with the upstream half-hollow punch rivet on the sheets and penetrates the uppermost sheet while it is widened due to the die under the bottom sheet in the bottom sheet without emerging from this sheet.
  • This process lasts approx. 0.5 sec.
  • setting forces of up to 90 kN are applied, depending on the sheet metal material and thickness.
  • 1 denotes the punch
  • 2 the hold-down
  • 3 the semi-hollow punch rivet
  • 4 and 5 the two sheets to be joined and 6 the die.
  • the semi-hollow punch rivet 3 is also fed in a known manner before the punch head 1 (position I).
  • the punch riveter is positioned at the riveting, so that the die 6 comes to rest against the lower plate 5 and the hold-down 2 with the punch 1 and the semi-hollow punch rivet 3 above the upper plate 4 is (position II).
  • the punch 1 moves with the semi-hollow punch rivet 3 in the direction of the upper sheet 4, to such an extent that the semi-hollow punch rivet 3 touches the sheet surface (position III), while the hold-down 2 remains just before the surface of the uppermost Sheet 4 remains without touching it.
  • a clamping force of 2 to 10 kN is applied for 0.1 to 2 sec.
  • This clamping force serves to distribute the adhesive between the sheets 4 and 5.
  • the clamping force exerted on the half-hollow punch rivet 3 is increased up to 75 kN up to the setting force of the semi-hollow punch rivet 3, so that the semi-hollow punch rivet 3 is driven into the sheets 4 and 5 to be joined (position IV).
  • the semi-hollow punch rivet 3 is widened within the lowermost sheet 5 in the usual manner, without leaving this sheet 5.
  • Upper sheet metal material AC-300 (aluminum 6060), Sheet thickness: 2.5 mm, Lower sheet metal material: H 220 LAD (steel), Sheet thickness: 1.42 mm, Glue between the Sheets: Betamate 1480, Semi-hollow punching rivet made of steel, C geometry, 5.3 x 5 mm, hardness 4 punch rivets: State of the art: Invention: Clamping force via hold-down: Clamping force via punch rivet: 6 kN, 6 kN, Setting force: 43 kN Setting force: 34 kN
  • the setting force can be reduced by more than 20%. This can be used for the same application lighter punch rivet.
  • the adhesive is distributed much more uniformly between the sheets.
  • the previously observed in the prior art air channels in the adhesive layer are substantially reduced or no longer occurred.
