Definitions

  • the invention relates to a riveting tool for setting and deforming rivets in the magazine riveting method, wherein a plurality of rivets are arranged one after the other on a common rivet mandrel and the riveting tool has at least one tubular shaft, a mouthpiece and a receptacle, the mouthpiece thereby facing at a fixing position first side of the rivet mandrel partially enclosing the housing head part of the riveting device and the receptacle is arranged on a second side facing away from the fixing position of the housing head part.
  • the rivet mandrel has a length such that it extends from the receptacle to beyond the mouthpiece, in this case arranged in sections within the mouthpiece, the at least one shaft and the receptacle and an end portion of the mandrel through the recording is frictionally fixed.
  • connection options such as bonding riveted joints are still widely used and are mainly used for joining sheet metal parts of various kinds.
  • Handnietsetzsysteme are designed, inter alia, as break-open rivet systems.
  • Such Dornbruch blind rivet systems are for example by the DE 198 18 756 A1 as well as the DE 44 06 946 A1 disclosed.
  • the rotational movement generated by the electric motor is transmitted to an axially fixed spindle nut, which is arranged on a spindle.
  • the rotational degrees of freedom of the spindle are locked, however, an axial movement of the spindle is possible.
  • the axially moving spindle exerts a force on the mandrel of a blind rivet during the execution of the movement.
  • the DE 41 26 602 A1 discloses an embodiment of a breakaway rivet system in which the rotational movement of the motor is transmitted via a plurality of gears and a shaft to the external toothing of the threaded spindle nut.
  • the threaded spindle nut is in this case also fixed axially and drives an axially movably designed hollow spindle.

  • the entire unit of the first motor, gearbox, mandrel shaft and mandrel is moved in the axial direction.
  • magazine rivet systems are also known in which, in contrast to breakstem blind rivet systems, in some cases hundreds of magazine blind rivets are arranged on a mandrel with lengths of up to more than one meter. This mandrel has no predetermined breaking points and is used for riveting all arranged on the mandrel magazine blind rivets. This results in particular by significantly lower cycle times advantages in the processing of a large number of riveted joints.
  • these magazine riveting systems are operated pneumatically or pneumatically-hydraulically, which always requires a compressed air source. Due to the need for a compressed air source, an operator of these magazine riveting systems is adversely restricted in his freedom of movement within a work environment.
  • the invention is therefore an object of the invention to provide a way to create an extremely portable riveting tool, which operates on the magazine riveting.

  • the rivet mandrel is movable by a force generated by the actuator or a generated torque.
  • a linear movement of the rivet mandrel should be provided, which takes place in the longitudinal direction of the rivet mandrel. If this linear movement of the fixing position is opposite, a setting operation would take place, with a rivet arranged on the rivet mandrel and in the direction of the fixing position in front of the mouthpiece jaws of the mouthpiece would be supported on the end face of the mouthpiece jaws, while at the tip not in the receptacle Nietdornkopf arranged the rivet mandrel passes through the rivet.
  • the rivet mandrel used can be threaded a variety of rivets, which in contrast to Dornbruchniet systems higher cycle time is achieved.
  • the rivet mandrel is introduced via the mouthpiece in the riveting tool and has due to the large number of rivets on a high compared to Dornbruchnieten length, so that the fixation of the rivet mandrel takes place on a side opposite the mouthpiece of the housing head part.

It is also possible to achieve an extension of the operating time, since a smaller mass has to be moved by the actuator. Accordingly, two performance forms are also conceivable. On the one hand, it is possible to carry out the transmission element as an internal thread element, wherein this has at least one section, which is designed as a hollow cylinder with an internal thread. On the other hand, it is possible to carry out the transmission element as an external thread element, which also has at least one section designed as a hollow cylinder, which, however, is equipped with an external thread.
