  • Riveters are commonly used to create a riveted connection between two or more materials, such as sheet metal, at a joint where the materials abut one another.
  • a plastically deformable, usually cylindrical connecting element is used, which is generally referred to as a rivet.
  • the rivet usually has a prefabricated setting head at one end.
  • the rivet is inserted into a connecting hole at the connection point up to the setting head and then the other end of the rivet is plastically formed into a closing head.
  • Common riveting devices usually include a riveting tool which is designed to effect a plastic deformation that forms the closing head.
  • the riveting devices have a drive device housed in a device housing.
  • the drive device is often electromechanical and includes, for example, an electric motor and a spindle gear designed as a ball screw with a threaded spindle and a spindle nut.
  • the spindle nut is driven by the electric motor and the threaded spindle is secured against twisting via torque supports, so that when the spindle nut rotates, the threaded spindle shifts axially and thereby acts on the riveting tool.
  • Such a riveting device is described in EP 0 527 414 Al.
  • the riveting device is designed and set up for blind riveting by exerting a pulling movement to pull a rivet mandrel out of the rivet body of a blind rivet while compressing the rivet body, creating a closing head, until the rivet mandrel tears off.
  • the torn-off rivet mandrel piece can be moved in the axial direction, i.e. in the direction of the pulling movement of the rivet mandrel, via a through hole in the threaded spindle and an adjoining pipe element must be disposed of in a collection container.
  • the collecting container is detachably attached to the device housing.
  • an intermediate piece of pipe is provided, which on the one hand is screwed to the device housing using screw elements and on the other hand serves as a receptacle into which the collecting container is releasably inserted with a corresponding extension.
  • the pipe section and the extension are often each provided with a thread and the connection of the collecting container to the pipe section is achieved by screws. So that the collecting container is still securely held on the riveting device when it is filled with remaining rivet mandrels, a considerable screw-in length is usually required. This means that the riveting device is relatively structural in the axial direction, especially when the collecting container is removed.
  • a basic riveting device includes a collecting container for residual rivet mandrels and a support structure for the collecting container.
  • An improvement in compactness is offered by an embodiment of the riveting device, in which a fastening mechanism is provided, which is set up in such a way that the collecting container can be brought into a fastening position on the support structure by a translational movement relative to the support structure along a spatial axis.
  • the fastening mechanism is further designed in such a way that the collecting container can be brought out of the fastening position by a rotational movement relative to the support structure about the spatial axis.

  • the proposed fastening mechanism allows the collection container to be mounted on the support structure without screwing.
  • the riveting device can be realized with a shorter axial length relative to the spatial axis when the collecting container is removed than is the case when the riveting device has a screw thread for screwing on the collecting container.
  • the proposed fastening mechanism enables the collection container to be dismantled from the support structure using a different type of movement than during assembly.
  • the holding connection between the collecting container and the support structure which acts in the direction of the spatial axis, can be made more solid, since no loosening takes place in this direction. Consequently, this counteracts any unwanted, automatic loosening of the collecting container due to its own weight, for example when it is filled with remaining rivet mandrels.

  • the snap connection can be dimensioned by appropriate design in such a way that, contrary to the snap direction, i.e. against the assembly direction, an unwanted automatic loosening of the collecting container due to its own weight, for example in the state filled with residual rivet mandrels, is avoided.
  • the improved riveting device should also be designed in such a way that the fastening mechanism is set up so that in the snap connection the collecting container is blocked relative to the support structure against rotation about the spatial axis up to a predetermined rotational force, i.e. there is a rotation lock. This counteracts unwanted, especially premature, loosening of the collecting container by a rotational force acting around the spatial axis. This makes it possible for the collecting container to only move out of the fastening position on the support structure when the predetermined rotational force is exceeded and the rotation lock is thus overcome.
  • a possible embodiment of the fastening connections can consist in one of the fastening connections having at least one latching projection and the other fastening connection having at least one recess, which can be used, for example, as a counter-latching structure.

  • the locking projection and / or the recess has a rounded contour on at least one end section having .

  • the rounded contour enables a sufficiently high holding force against twisting as long as the locking projection is completely in the recess. The further the locking projection emerges from the recess, the lower the holding force against twisting becomes. In this respect, a rounded contour is recommended, as it facilitates easy loosening if the holding force is exceeded.
