Definitions
- the invention relates to a method according to the preamble of the first claim
- Punch rivets are understood to mean a riveting method in accordance with DIN 8593-5, Issue Sept 2003, in which a full rivet or half-tubular rivet is driven by a ram through at least two unperforated sheet-like components by means of a blank holder.
- a die is arranged on the component side facing away from the stamp 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 form gleichige connection between the punch rivet and the lower component is formed
- 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 hold-down
- Such punch riveting tongs are usually used on robots fastened, which then drive the punch riveter to the fastening point
- Such a system for a semi-hollow rivet for example, describes the US-A 5,752,305
- clamping forces of some 100 N up to 15 kN are referred to as usual, wherein clamping forces in such a height according to the US patent, a deep drawing process in the sheets in the Punch rivet is to be avoided, which has turned out to be in practice but not true
- Object of the present invention is to propose a method for setting punched rivets, while maintaining the known Punch riveting with which a reduction of Fugekrafte is possible
- the development according to claim 2 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 punch path
- the claims 4 and 5 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
- 1 denotes the punch
- 2 the hold-down
- 3 the semi-hollow punch rivet
- 4 and 5 the two sheets to be joined
- 6 the die
- the half-hollow punch rivet 3 is also supplied in front of the punch head 1 in a known manner (position I)
- the punch riveter is positioned at the riveting point, so that the die 6 comes to bear 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 half-hollow punch rivet 3 in the direction of the upper sheet 4, namely so far that the half-hollow punch rivet 3 touches the sheet metal surface (position III), while the hold-down 2 is still 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 over the semi-hollow punch rivet 3
- 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 half-hollow punch rivet 3 is driven into the sheets 4 and 5 to be joined (position IV).
- Upper sheet material AC-300 (aluminum 6060),
- the setting force can be reduced by more than 20%.
- lighter punched nipples can be used for the same application
- the adhesive is distributed much more uniformly between the sheets.
- the air channels previously observed in the prior art in the adhesive layer are substantially reduced or no longer occur
