Definitions

  • the invention relates to a tool for joining components, in particular at least two sheet metal sheets lying on top of one another, with a housing in which a primary plunger consisting of a punch and a hold-down device is mounted such that it can be driven in the axial direction, a die assigned to the punch and a die relative to the housing Element feed movable in the axial direction, via which auxiliary joining parts, in particular rivets, can be fed to the primary ram.
  • Such a tool is, for example, from EP 2 644 298 B1 known.
  • This is a setting tool for punch riveting.
  • a rivet is driven into the two stacked components via the primary plunger to connect them.
  • the element feed via which the rivet is brought into connection with the primary ram, moves together with the ram in the direction of the die assigned to it.
  • the tool can be driven hydraulically or electrically. With this tool, short cycle times can be carried out because the primary ram and the hold-down device, together with the element feeder for picking up the rivet, only have to cover a short distance from the rivet position to the rivet pick-up position and vice versa.
  • the disadvantage of this is the poor component accessibility due to the spatial size of the element feed.
  • the EP 1 099 495 B1 known joining device is provided that the element feed (rivet feed) is fixed to the housing and the punch must move back completely after driving in the rivet in order to be able to feed a new rivet to the punch. This slows down the cycle time of the joining device.
  • the two known joining devices have either combined the disadvantage of poor building accessibility with the advantage of short cycle times or the advantage of good component accessibility with the disadvantage of long cycle times.
  • the EP 3 242 760 B1 discloses a tool for joining components with a feed unit for transferring a connecting element to the setting head, which can be moved from an initial position into a freely adjustable intermediate position. As a result, the connecting element can be transferred to the setting head at different positions between the starting position and the working position.
  • the setting head and the feed unit can be moved independently of one another in one direction to the working position.
  • the invention is based on the object of improving the joining device described at the beginning in such a way that the two advantages of the different joining devices can be combined with one another and the two disadvantages can be compensated.
  • a generic tool for joining components is characterized in that at least one position I, which is at least indirectly coupled to the primary plunger and at least one position II decoupled from the primary plunger, can be occupied by the element feed, and the element feed in the coupled position I together with the Primary plunger is movable in the axial direction, and remains stationary in the decoupled position II when the primary plunger moves relative to the housing.
  • the short cycle time can be achieved in one case if the component accessibility plays a subordinate or even secondary role and the element feeder is ready at any time to feed the auxiliary joining part to the primary plunger and in another case the element feeder can then be operated in a stationary manner with the housing , if the length of the cycle time is of minor importance because good component accessibility must be created in the joining operation.
  • the element feed is preferably coupled to the primary ram by a first coupling element, which is preferably a fluid cylinder and in particular a pneumatic cylinder.
  • the coupling element can also comprise an electric drive.
  • the primary ram is preferably surrounded by the secondary ram to which the element feed is attached.
  • the secondary tappet can preferably be moved together with the primary tappet in the axial direction or the secondary tappet can be fixed in the housing, while the primary tappet can move in the axial direction.
  • the secondary plunger can be fixed in at least two different positions in the housing.
  • At least one radial recess or bore can be provided in the tubular secondary plunger, with which, in particular, a piston rod of the fluid cylinder can preferably be brought into engagement.
  • a hold-down device which can be coupled and decoupled from the secondary ram, is preferably arranged between the primary ram and the secondary ram.
  • the coupling of the hold-down device to the secondary ram is preferably carried out via a second coupling element, which in particular is preferably a fluid cylinder and very particularly preferably a pneumatic cylinder.
  • An electric drive can also be provided here.
  • the joining tool consists of the C-shaped bent bracket 10 on the upper leg of which the housing 1 is arranged, which consists of a punch 9 and a Hold-down 7 existing primary ram 2 receives.
  • the die 3, which runs coaxially to the primary ram 2, is arranged on the lower leg of the bracket 10.
  • the sheets B 1 , B 2 to be connected to one another are arranged between the primary ram 2 and the die 3.
  • FIG 4 shows the structure of the upper part of the tool.
  • the electric motor 11 is used to drive the tool.
  • the rotary movement initiated by the electric motor 11 is converted into an axial movement of the punch 9 via a toothed belt drive 12 and a roller screw drive 13 (not shown in detail) with an anti-twist device in the housing 1.
  • the punch 9 is surrounded coaxially by the hold-down device 7, which in turn is arranged coaxially within a secondary ram 6.
  • the secondary plunger 6 can either be fixed in its position in the housing 1 or it can execute the drive movement in the axial direction A of the plunger 9 or hold-down 7 and primary plunger 2.
  • the element feeder 4.1 of the element feeder 4 is arranged on its free end of the secondary ram 6 assigned to the die 3 and can be attached to or detached from the hold-down 7 via the coupling element 8.
  • the coupling element 8 is preferably a pneumatic cylinder which can engage with its piston rod in a hole or recess provided in the hold-down device 7. Once the piston rod has been inserted into the recess, the element feed 4 is coupled to the hold-down device 7. When the piston rod is retracted into the pneumatic cylinder, the element feed 4 is decoupled from the hold-down device 7.
  • another coupling element 5 is arranged, which is also preferably designed as a pneumatic cylinder.
  • This pneumatic cylinder 5 interacts with its piston rod 5.1 with several recesses or bores 6.1, 6.2 provided in the upper part of the secondary plunger 6 guided in the housing 1. If the piston rod 5.1 is immersed in one of the bores 6.1, 6.2, the secondary plunger 6 is fixed within the housing 1, so that the upper position of the secondary plunger 6 and thus its distance from the die 3 is fixed. If the coupling element 5 is deactivated, that is to say the piston rod 5.1 of the pneumatic cylinder 5 is disengaged from the secondary plunger 6, the element feed can 4 can be moved together with the primary ram 2 in the direction of the die 3.
  • the coupling element 8 If the coupling element 8 is activated, the element feed 4 is coupled with the hold-down 7 so that both do not remain stationary with respect to the housing 1, but are moved axially with the primary plunger 2 and the previously received rivet in the direction of the die 3 in order to enter the metal sheets B 1 , B 2 penetrate and connect them to one another by means of the auxiliary joining part.
  • a pin that plunges into the recesses or bores can also be driven by an electric drive.
  • the piston rod 5.1 of the pneumatic cylinder 5 must be removed from the bore 6.1 or 6.2 of the secondary plunger 6, so the pneumatic cylinder 5 must be deactivated. If the ram 2 is now driven, the element feed 4 moves together with the hold-down 7 in the direction of the die 3, as Figures 14a , 14b demonstrate. If the pneumatic cylinder 8 is deactivated and the piston rod 8.1 is moved out of the recess 7.1, the element feed 4 is no longer coupled to the hold-down 7 via its element feeder 4.1. If the pneumatic cylinder 5 is then activated and its piston rod 5.1 is moved into one of the bores 6.1, 6.2, the secondary plunger 6 is fixed in the housing 1 and cannot follow the hold-down 7 and thus the punch 9.
  • the element feed 4 is thus not moved in the direction of the die 3 and sufficient access space to the components (sheets B1, B2) is ensured.
  • the location of the holes 6.1, 6.2 determines the stationary position of the element feed 4 in relation to the die 3 and thus the size of the access space to the workpieces B1, B2 to be connected to one another.
