Definitions
- the present invention relates to a method and a punch riveting apparatus for connecting at least two components.
- Punching riveting methods are used to connect at least two components that are particularly flat in a connection region (joining partner).
- a punch riveting method is characterized in that a pre-punching of the components to be joined together is not required. Rather, a punch rivet is pressed by means of a punch or a punch tool in the at least two components, being ensured by a correspondingly shaped counter-holder, for example.
- a punch rivet is pressed by means of a punch or a punch tool in the at least two components, being ensured by a correspondingly shaped counter-holder, for example.
- a die which cooperates with the punch tool, that the rivet or the components in a certain Deforming manner to produce a positive and positive connection between the components.
- Ultrasonic punch riveting known, in which a vibration generator, such as.
- An ultrasonic generator is used to enable one or more components when connecting the components in vibration. By this vibration, for example, the expended force is reduced to push the rivet.
- a film is introduced in a punch riveting process between the counter-holder and a component facing the counter-holder in order to avoid direct contact between counter-holder and component.
- the film used acts in particular as a sliding or protective film and in particular is sufficiently ductile or elastically deformable in order to conform to the counter-holder during the punch riveting process.
- a counter-holder for a punch riveting device is usually milled or turned, hardened and possibly mechanically polished or ground.
- the counter-holder thus has a relatively rough surface, on which material can adhere from a component abutting the punch riveting process. This is especially the case, for example, when punching riveting soft materials such as aluminum.
- the introduced foil prevents direct contact between the component and the counterholder so that material can no longer adhere.
- the service life of the counter-holder is increased (thereby lengthening the counterholder change intervals) and the reproducibility of the rivet connections is improved by avoiding buildup in the counter-holder.
- a film for punch riveting with a vibrator, eg. An ultrasonic generator.
- a portion of the punch riveting apparatus is vibrated during the punch riveting operation so that the rivet can be more easily pressed into the components to be connected.
- a relative movement can arise between the counter-holder and the component adjacent thereto, through which not only adhesions of material, but, for example, also alloys can occur in conventional counter-holders. In the invention, this is no longer or at least hardly the case.
- Such punch riveting have special advantages in automotive lightweight body construction, since the vibration or ultrasonic punch riveting facilitates with the appropriately designed equipment many joining tasks in the field of material mixing and new material thickness combinations possible.
- a punch riveter with vibration support may also be used to advantage in other areas (such as in the aerospace industry or in cable car and gondola construction) and / or for joining other materials.
- punching riveting the process forces required for the riveting process, usually very high, are considerably reduced.
- process advantages such as the improvement of the cutting process or the material separation during punching, the change, the plastic deformation capacity of material (eg Al / Mg sheet metal or die-cast) and the avoidance of collapsing rivet elements
- the film is provided as sheets (ie, singulated pieces) or as rolls (ie, endless web).
- a preferred punch riveting apparatus has an associated foil insertion device in order to introduce the foil sheets or foil web between the component and the counterholder.
- the foil has metal.
- a metal foil is relatively robust and tear-resistant and can reliably prevent direct contact between component and counter-holder.
- the film may comprise plastic (e.g., PTFE (Teflon)). Plastic is usually less expensive than metal and easier to handle due to its low density.
- a release-containing film such as e.g. a ceramic or polymer based (e.g., PTFE) coated (metal) foil), which performs the function of a permanent separation of the original 'mating component' contact mating. Due to the isolation of the contact pairing between the counterholder and the component, adhesions in the counter holder are avoided.
- suitable lubricant films for example, (metal) film systems with graphite, wax or oil coating
- suitable lubricant films provide additional sliding assistance and thereby achieve a friction reduction coupled with a Fügekraftredulement.
- each film section (ie, during the joining of the at least two components with the counter-holder in contact portion of the film) is used only for a single punch riveting operation. In this way you can prevent a through a punch riveting operation, possibly damaged or contaminated film section is reused and leads to damage or contamination of the component and / or the counter-holder.
- the film can also be used as corrosion protection on the product, i. the portion of the film remains on the component.
- a thin stainless steel foil e.g., No. 1.4301 or 1.4303 or 1.4567
- another corrosion resistant foil could be used.
- FIGS. 1a to 1d a punch riveting apparatus 10 is shown at various stages of performing a punch riveting process.
- the punch riveting apparatus 10 has a punch 15, which for example has a round cross section.
- the punch 15 is radially surrounded by a sleeve-shaped hold-down 16 and arranged movable relative to this in the longitudinal direction.
- the punch 15 is coupled to a drive, not shown here, for example a hydraulic or pneumatic drive, which serves to apply a force F required to press a rivet 20 into the two components 11, 12.
- the hold-down 16 is adapted to press against the surface of the die 15 facing member 11 with a hold-down force.
- a separate drive can be provided.
- the hold-down can also be coupled to the drive of the punch 15, for example by means of a spring.
- an inventive counter-holder 18 which acts as a die here, arranged.
- the punch 15 and the die 18 are movable relative to each other in the direction of a longitudinal axis 19, in the direction of which also the hold-down 16 are arranged to be movable.
- the hold-down 16 and the die 18 serve to clamp or compress the two components 11, 12 between the hold-down 16 and the die 18 during processing by the punch 15.
- the die 18 has, on the side facing the component 12, a region 21 with a flat surface, from which a trough-shaped or recess 22 extends.
- the rivet 20 preferably consists of a material which is harder than the materials of the two components 11, 12, at least in the region of the rivet shank 24.
- the planar top side 26 facing away from the component 11 is arranged in operative connection with the ram 15, which is secured to the top side 26 of FIG Rivet 20 is flat.
- the punch 15 is operatively connected to a vibration generator 30 for generating vibrations.
- a vibration generator 30 for generating vibrations.
- ultrasonic vibrations with an amplitude (distance between maximum positive and negative amplitude of a vibration) between 10 .mu.m and 110 .mu.m (or an amplitude between 5 .mu.m and 55 .mu.m) and a frequency between 15 kHz and 35 kHz are generated.
- vibrations are coupled by the vibrator 30 via the punch 15 in the rivet 20.
- the coupling-in direction of the vibrations of the vibration generator 30 can take place, for example, parallel to the longitudinal axis 19, that is to say parallel to the joining direction of the rivet 20 into the components 11, 12
- FIG. 1a Phase shown represents a beginning of the Stanzniethabilits in which the rivet shank 24 comes into operative connection with the top of the component 11. In this case, the punch 15 is pressed with the force F against the stamp 15 facing member 11.
- the rivet shank 24 initially cuts or punches into the component 11.
- the two components 11, 12 are plastically deformed, wherein the recess 22 facing the component 12 is pressed in the corresponding areas in the recess 22.
- the rivet shank 24 is spread outwards in the region of the recess 22, whereby the two components 11, 12 are securely connected to each other in the axial direction in a positive and non-positive manner.
- FIG. 2 and 3 two preferred embodiments of a punch riveting device according to the invention are shown in fragmentary form in a schematic side view or sectional view and designated by 101 and 102, respectively.
- the elements corresponding to those of the punch riveting device 10 FIG. 1 correspond, are provided with the same reference numerals and will not be explained again at this point.
- the punch riveting devices 101 and 102 are shown in a state in which the die 18 is shown downwardly from each of the components 11 and 12 to be connected.
- the die is not movable relative to a frame (for example, pliers) of the punch riveting apparatus, but the punch and the downholder.
- a film 41 and 42 is introduced.
- the film 41 is provided as sheet goods
- the film 42 is provided as a roll product.
- separated film sheets 41 are accordingly introduced between component 12 and die 18, in order to avoid direct contact between component 12 and die 18 during the punch riveting process.
- a film insertion device 411 is provided, which introduces the separated film sheets, for example by means of rollers or gripping arms between the component 12 and the die 18.
- the punch riveting device 102 has a film insertion device 421 which, in the example shown, has a plurality of rollers over which the web-shaped film (film web) 42 is guided. Specifically, an unwind roll 422, two idler rolls 423, and a take-up roll 424 are shown.
- the illustrated embodiments have in common that a respective foil section, which comes into contact with the die 18 in a punch riveting operation, is used only for a single punch riveting operation and after this punch riveting operation the foil section between the component 12 and the die 18 is removed again.
