Definitions

  • the present invention relates to a method for operating a punch riveting apparatus, as well as such a punch riveting apparatus and a mouthpiece for such a punch riveting apparatus.
  • Joining methods such as riveting methods, are used to join at least two components that are particularly flat in a connection region (joint partner).
  • a punch riveting method is characterized, for example, by the fact that pre-punching of the components to be joined together is not required. Rather, a rivet is pressed as a joining element by means of a joining tool, which includes a stamp in the joining direction at least two components in a joining direction, which can be ensured by a correspondingly shaped counter-holder, for example.
  • a joining tool which includes a stamp in the joining direction at least two components in a joining direction, which can be ensured by a correspondingly shaped counter-holder, for example.
  • the rivet or components deform in a particular manner to produce a positive and positive connection between the components.
  • a so-called ultrasonic punch riveting method in which a vibration generator, such as an ultrasonic generator, is used to cause one or more components to vibrate when connecting the components.
  • a vibration generator such as an ultrasonic generator
  • the expended force is reduced to push the rivet.
  • the invention is based on a method for operating a punch rivet device, which has a setting unit, by means of which a rivet can be held, and which has a ram, by means of which the rivet can be acted upon with force and introduced into at least one component in the joining direction in a riveting operation, having.
  • rivets can be performed in a predefined orientation.
  • the profile hose can then be connected at a suitable location in the joining tool, so that in each case a rivet can be supplied in the desired position or inserted into the joining tool for a riveting operation.
  • the rivets can be introduced after a separation, for example by means of compressed air in the joining tool.
  • the joining tool has in addition to the stamp usually a so-called. Hold-down, which surrounds the punch and serves to guide the rivet during the riveting process.
  • the hold-down device acts on the component while the punch is moved relative to the hold-down in order to press the rivet into the component (or the components).
  • the setting unit in particular also the punch, a correspondingly long and thin portion on the component side end (or the joining tool can be formed accordingly), so that in the mentioned possibilities for feeding and receiving the rivet in the setting unit in addition to the connection the corresponding components, so for example, the belt or the profile hose, in the area between the point of connection and the component sufficient space remains to ensure sufficient accessibility for a variety of activities.
  • the setting unit for introducing the rivet is placed in the setting unit in a basic position in which one of the at least one Component facing mouthpiece of the setting unit of a region in which the at least one component is to be positioned during the riveting process, is spaced.
  • a storage container structurally separate from the setting unit, in which the rivet is located, is moved to the setting unit and the rivet is automated from the storage container into the mouthpiece, in particular by a movement of the storage container or a handling component (eg slide, Plunger or similar) introduced.
  • the rivet can then be held in the mouthpiece, for example, by magnetic force and / or negative pressure and / or suitable holding elements.
  • the storage container can be removed from the setting unit.
  • the setting unit for introducing the rivet is brought into the at least one component by means of a linear movement from the basic position in a joining position in which the mouthpiece rests against one of the components.
  • the proposed solution thus no longer requires connection of a belt, a profile hose or the like to the setting unit, which means that accessibility remains ensured both when the rivet is received or inserted and during the riveting operation, even if the setting unit is shorter and / or shorter. or wider than conventional punch riveting devices.
  • the rivet in the storage container which may in particular be a magazine, held by means of a holding or guiding device in a predetermined position when the rivet is introduced into the setting unit.
  • a rail may be used which has a contour adapted to a profile of the rivet.
  • the storage container or the handling component for introducing the rivet into the mouthpiece is moved in a direction of movement substantially perpendicular to the joining direction.
  • a suitable embodiment of the mouthpiece is advantageous, that is, for example, it may be provided a suitable lateral opening.
  • Such a movement is very easy to reproduce, resulting in the most accurate positioning of the rivet in the mouthpiece or an accurate introduction into the mouthpiece.
  • the setting unit is brought by a linear movement of the setting unit parallel to the joining direction of the basic position in the joining position (and in particular also back again).
  • the movement can be made even more reproducible and performed in particular by means of existing drives and guides or bearings.
  • an ultrasonic punch riveting apparatus in which oscillations are generated by means of a vibration generator, which are coupled to the stamp, since here, as already mentioned, the advantages to be achieved are particularly large, in particular in terms of space or accessibility in the joining area.

  • the setting unit can be brought into a basic position in which a mouthpiece of the setting unit facing the at least one component is spaced from a region in which the at least one component is to be positioned during the riveting operation, wherein in the basic position the storage container is so is movable to the setting unit, that the rivet from the storage container into the mouthpiece can be introduced.
  • the storage container is removable from the setting unit, and the setting unit can be brought by means of a linear movement from the basic position in a joining position (and in particular also back), in which the mouthpiece rests against one of the components.
  • the invention further relates to a mouthpiece for a setting unit of a punch riveting device.
