Definitions

  • the invention relates to a stamped riveting system for groupwise riveting of fasteners on preformed sheet metal and in particular body parts, according to the preamble of claim 1.
  • the to be fitted with the fasteners sheet metal sections are substantially perpendicular to the common Niethubides the riveting, otherwise it comes to riveting with obliquely riveted fasteners and larger differences in inclination of the sheet metal sections even a malfunction of the stamped riveting.
  • a riveting system for groupwise riveting fasteners to mutually different inclined sheet sections using a Hubumlenkkinematik is known from US-A-1,995,486.
  • the object of the invention is to provide a stamped riveting of the type mentioned in such a way that even at mutually different inclined sheet metal sections a proper, groupwise riveting fasteners is made possible in a structurally simple manner.
  • the linear drive guarantees a secure and accurate riveting of the fasteners to differently inclined sheet metal sections in a single operation, without the mutually angular offset riveting units require structurally complex each separate Hubantriebe.
  • virtually any curved or folded standard sheet metal parts at the same time can be equipped with punching elements at a plurality of desired riveting positions with a simply constructed punch riveting system.
  • the punch riveting system shown in the figures is used for simultaneous, groupwise riveting of punching nuts, punching pins or - as shown - punch rivets 1 (Fig. 3) on preformed Rohkarosserie former 2, 3 and contains as Main components a clamping tool 4, consisting of an upper and a lower, the sheet metal parts 2, 3 in the closed position of the clamping tool 4 (Fig. 2) surface conform between clamping tool part 5, 6, as well as several, in the rivet positions of the sheet metal parts 2, 3 arranged Riveting units 7 and acting in the stroke direction H linear drive including a lifting plate 8 for actuating the clamping tool 4 and the Nietsetzein units 7th
  • the riveting units 7 at the individual rivet positions must each be perpendicular to the sheet metal part contour, i. be aligned in the direction of the local surface normal. Accordingly, the riveting units 7.1 and 7.2 are positioned parallel to the stroke direction H, while the riveting units 7.3 and 7.4 are arranged angularly offset from the stroke direction H in accordance with the inclination of the respective sheet metal part sections to be riveted.
  • the riveting units 7 each comprise a rivet setting head 9 arranged on the upper tool part 5 and a corresponding riveting die 10 arranged on the lower tool part 6.
  • Each rivet setting head 9 in turn contains a housing 11 which is attached to a rivet head 9 Hubstsammlungel 12 fastened and liftable in the upper tool part 5 is guided.
  • a limited in the housing 11 slidably mounted blank holder 13 is pressed by a compression spring 14 (Fig. 2) in the extended position shown in Fig. 1.
  • a compression spring 14 (Fig. 2) in a central rivet channel 15 of the sheet holder 13 is a rivet punches 16 fixed to the housing.
  • a rivet rivet 1 is automatically fed to the rivet heads 9 via a laterally opening into the rivet channel 15, when the sheet holder 13 is in the extended position in which the Riveting punch 16 is retracted in the rivet 15 to behind the mouth of the feed channel 17.
  • the rivet matrices 10 of the parallel to the stroke direction H of the lifting plate 8 acting riveting units 7.1 and 7.2 are flush with the clamping surface of the lower tool part 6 and fixedly mounted on this, while the riveting tools 10 of the angular displacement to the stroke direction H acting Nietsetzmatien 7.3 and 7.4 respectively attached to a die stamp 18 and over these in the lower tool part 6 between a voltage applied to the back of the sheet metal part 2 working position (Fig. 2) and a lifted off the sheet metal part 2 release position (Fig. 1 and 3) are guided in a liftable manner.
  • All riveting units 7.1 to 7.4 are operated synchronously by the linear drive (lifting plate 8). While the lift rods 12 of the riveting units 7.1 and 7.2 are fixedly connected to the lifting plate 8, the actuation of the angularly displaced riveting units 7.3 and 7.4 takes place via a deflection kinematics, which cooperate wedge-shaped with one another and e.g. via dovetail guides slidingly coupled together contact surfaces 19, 20 between the Hubstsammlungeln 12 and hubplattenfesten support bodies 21 and other, also wedge-shaped cooperating and positively coupled in the sliding direction contact surfaces 22, 23 between the Matrizenstkovn 18 and stationarily attached to the base plate 24 supports 25 contains.
  • both tool parts 5, 6 together until lowered to the stop of the lower tool part 6 on the base plate 24, whereby the Nietmatrizen 10 of the angular offset Nietsetzmatien 7 are advanced over the contact surfaces 22, 23 in the voltage applied to the sheet metal part back working position.
  • the surface normal and thus also the Nieaufichtung the corresponding Nietsetzhow in the riveting perpendicular to the stroke direction H of the linear drive, formed during riveting on the back of the die-side sheet metal part 2 equal in shape to a compensating groove 28 at the front die end Rivet 29 from, which would hinder the removal of the sheet metal parts 2, 3, if the rivet 10 would be firmly connected to the lower tool part 6.
  • the Nietmatrize 10 is reversed after completion of the riveting operation by means of the linear drive and the Hubumlenkkinematik in the retraction position shown in Fig. 3, so that it releases the Nietwulst 29 and the sheet metal parts 2, 3 can be easily removed from the clamping tool 4.
