  • Generic joining elements and methods are already out of the DE 10 2006 013 529 A1 known, which should be considered fully disclosed. Such joining elements are used for joining two adjoining workpieces, in particular sheet metal components of different hardness. Such a joining element has a substantially rotationally symmetrical with respect to an at least zweizähligen rotational symmetry axis penetration portion. When using the joining element of this is first moved through rotational and translational movement through the first workpiece and then pressed into the second workpiece, without penetrating this. As a result of the friction occurring when pressing in, the joining element is connected to the second workpiece in a material-locking manner while the workpieces are held in abutment with one another. In other words, it is a combination of a separating and a joining method, wherein first the first workpiece is penetrated without pre-drilling and then by friction welding a material connection with the second workpiece is produced. However, the known from the prior art joining elements are problematic in handling and lead to uneven quality of the resulting joint connections.
  • Of the The present invention is therefore based on the object, a joining element as well as to develop a method of the type mentioned in the beginning, that the process safety of joining two workpieces is improved and increases the joint quality becomes.
  • These Task is characterized by a joining element with the characteristics of Patent claim 1, a joining element with the features of Patent claim 2, a joining element with the features of Patent claim 6 and a method having the features of the claim 16 solved.
  • One generic joining element for joining two adjoining workpieces has a penetration portion which essentially relates to at least one two-fold rotational symmetry axis rotationally symmetric is trained. The penetration section is by rotary and translational movement through a first workpiece hindurchbewegbar and pressed into a second workpiece, without to penetrate this, wherein the joining element thereby when pressing friction occurring cohesively is connectable to the second workpiece while the workpieces are held in abutment against each other. It arises So a form and / or adhesion between the Fügelement and the first workpiece and a material connection and, where appropriate an additional adhesion between the joining element and the second workpiece.
  • According to the invention provided that the penetration section has a convex projection having a flattening, which is an annular Edge has. This allows a particularly simple design of the joining element, which alone due to the friction between the joining element and the first workpiece in this invade and finally penetrate this, without that complex geometries are necessary.
  • A alternative embodiment of the invention is in claim 2 described. This has the same generic characteristics as the embodiment described above differs However, the fact that the penetration section at least one having geometrically defined cutting edge. This is the penetration the first workpiece easier because through the cutting edge first cutting a through hole for the Penetration section is created. Because the second workpiece usually formed of a harder workpiece is, there takes place no cutting removal, but rather by the penetration section generates the desired frictional heat, which to a cohesive connection of the joining element with the second workpiece leads.
  • In a preferred embodiment, the at least one geometrically determined cutting edge in a spiral arm shape a rotational symmetry axis of the penetration area. This allows a particularly homogeneous material removal over the entire cutting surface of the penetration section.
  • Farther the penetration section preferably has at least one further, straight line extending geometrically determined cutting edge. In particular in the combination of the two cutting gradients becomes a special one favorable material removal and thus a particularly process-reliable Connecting the two workpieces allows.
  • In a further preferred embodiment, the at least one geometrically determined cutting edge is provided on a projection of the penetration section, which forms an undercut with a planar end face of the penetration section. The undercut creates evasion spaces for resulting chips, which are cleared from the immediate cutting area so quickly can be before they leave the penetration area of the penetration section in the first workpiece.
  • In another alternative embodiment, also the generic features of the two described above Divides embodiments, it is provided that the penetration section a convex projection with at least one slit-shaped recess having. Here, too, alternative rooms will be created Created chips or abrasion, which is easier from the Penetration can be dissipated. Preferably the spherical projection while two arranged at right angles to each other slit-shaped recesses.
  • The features described below can be combined with all three alternative embodiments of the invention. In a further embodiment of the invention, the penetration portion may at least partially have a polygonal profile. Under polygonal is here in the sense of DIN 32711 following a non-circular profile with rounded corners to understand. This again free space for the removal of chips and abrasion created, which further improves the process reliability in the use of the joining element.
  • Also for the material engineering design of the joining element There are several alternative or usable in any combination Options. Preferably, the joining element an austenitic structure, which is particularly advantageous to him Gives strength properties. The joining element is preferred while a manganese and / or boron-containing steel, in particular made of 23MnB4 or 22MnB5.
  • The Surface of the joining element can by carburizing be hardened, creating a particularly resistant Insert layer is created. The Vickers hardness of the surface layer is preferably greater than 400 HV.
  • To the Further improving the surface properties may additionally a surface coating may be provided. This can through a chemical nickel process, by plasma spraying, through kinetic cold gas compacting, by flame spraying, by hard chromium plating, by tin-nickel plating or by physical vapor deposition be upset. For particularly good hardness can the joining element at least partially made of high-carbon steel, especially with cementite structure.
  • Around the cutting action of the joining element during penetration of the first workpiece can be improved in the surface of the joining element continues at least partially introduced particles with abrasive effect.
  • at these particles may be, for example, corundum chips.
  • The The invention further relates to a method for joining at least of two adjoining workpieces by means of a Joining element, in which the joining element by rotary and translational movements through a first workpiece of moved through both workpieces and into the second workpiece is pressed without the second workpiece too penetrate, and thereby by the resulting impressions Friction a cohesive connection of the joining element is made with the second workpiece while the workpieces are held in abutment against each other. According to the invention provided here that a joining element of the above-described Type is used. This results in the basis of the already described improvements in the Use of the joining element and thus an improved Process security for the entire process.
  • in the Following is the invention and its embodiments will be explained in more detail with reference to the drawings. Hereby show:
  • 1 to 5 various embodiments of joining elements according to the invention in each case in a sectional view and plan view;
  • 6A to 6E a schematic representation of the sequence of an embodiment of a method according to the invention.
  • One in the 1A and 1B shown, as a whole with 10 designated joining element has a rotationally symmetric body 12 and a penetration section 14 on. When using the joining element penetrates the penetration section 14 a first, softer workpiece and is then pressed in rotation into a second harder workpiece. Due to the frictional heat, both edge regions of the penetration section melt 14 as well as the second workpiece, so that there is a cohesive connection. At the base body 12 is a ring-shaped surrounding bridge 16 provided, which in the end position of the joining element 10 comes into contact with the first workpiece. The penetration section 14 has a cylindrical base part 18 and a crowned end area 20 on. The crowned end area 20 has a flattening 22 coming from an annular edge 24 will circulate.
  • The in the 2A to 2C shown alternative embodiment of a joining element 10 under differs from this only by the formation of the Eindringabschnitts 14 , The crowned end area 20 of the penetration section 14 has here additional geometrically determined cutting. A first set of four cutting edges 26 runs thereby spiralarmförmig with respect to the symmetry axis 28 of the joining element 10 , A second set of cutting 30 is straight and slightly eccentric with respect to the axis of symmetry 28 , As a result, the material removal in the first workpiece upon penetration of the joining element 10 improved.
  • The in the 3A and 3B shown alternative embodiment of the joining element 10 also differs only in the design of the crowned end 20 of the penetration section 14 from the previously shown embodiments. Again, here are on a flattening 22 the crowned end area 20 geometrically determined cutting 32 provided, which is half-dome shaped over the flattening 22 protrude and an undercut 34 train with this.
  • 4A and 4B show a further alternative embodiment of a joining element 10 , which differs from the previously shown in that in the crowned end 20 of the penetration section 14 slit-shaped grooves 36 are provided, which are at right angles to each other. This also improves the penetration of the penetration section into the first workpiece.
  • The 5A and 5B show a further alternative embodiment of a joining element 10 , In contrast to the previously shown embodiments, the base part 18 of the penetration section 14 not cylindrically symmetrical here, but as siebenzählig rotationally symmetrical polygon with rounded corners. In the embodiment shown, the crowned end portion 20 again with a flattening 22 provided, which of an annular edge 24 is circulating. The design of the base section 18 according to 5B However, it can also be used with all other designs of the end sector 20 according to the 1 to 4 be combined.
  • 6A to 6E Finally, show individual process steps when joining two components by means of a joining element 10 , As in 6A First shown is a first sheet metal component 38 and a second sheet metal component 40 by means of a tensioning device 42 and a counterpart 44 brought in and held. The first sheet metal component 38 consists of a softer material than the second sheet metal component 40 , For example, the first component may be 38 around an aluminum sheet and in the second component 40 to trade a steel sheet. Of course, other material combinations are conceivable. In a tool holder 46 will, as in 6B shown a joining element 10 clamped and rotating with feed on the sheet metal components 38 and 40 fed. As in 6C As shown penetrates the penetration section 14 of the joining element 10 first, the first sheet metal component 38 under material removal. By feeding the tool holder 46 becomes the joining element 10 after penetrating the first sheet metal component in the second sheet metal component 40 pressed. By the rotation of the tool holder 46 and thus also of the joining element 10 Frictional heat arises. The temperature is high enough to both the second sheet metal part 40 as well as the joining element 10 to melt, so will be like in 6B shown the rotational movement of the tool holder 46 set. The partly melted joining element 10 is thus in the also partly melted sheet metal component 40 pressed, the contact pressure of the tool holder 46 is maintained. This condition is met until, as in 6E shown, the melt is solidified again, leaving a cohesive joining area 48 between the second sheet metal component 40 and the joining element 10 results. In this state comes the bridge 16 of the basic body 12 of the joining element in contact with the surface 50 of the first sheet metal component 38 , so that at the same time a non-positive connection between the joining element 10 , Sheet metal component 38 and sheet metal component 40 is achieved. The first sheet 38 becomes as it were between the joining element 10 and the second sheet metal component 40 braced.
