Definitions

  • the riveting i. the rivet bead is formed by means of a dome penetrating the blind rivet from the side from which the blind rivet is inserted through the metal sheets.
  • the other side of the sheets need not be accessible.
  • the mandrel breaks off after riveting or it is pulled through.
  • sheets other, in particular plate-shaped components with a
  • blind rivet are connected. Advantages of the blind rivet are that it is a low-cost, easy and fast to produce fastener that is easy to use, and that the sheets or other components to be joined must be accessible from one side only.
  • the object of the invention is to propose a synchronblindniet which is riveted by screwing a screw from the side of which he is plugged through the components to be connected.
  • the synchronblindniet invention is tubular, wherein its outer circumference, at least in a region which is located in set ringrobindniet in one of the components to be connected, is not circular.
  • the outer circumference of the invention is tubular, wherein its outer circumference, at least in a region which is located in set ringrobindniet in one of the components to be connected, is not circular.
  • erblindniets may for example be a polygon. Also, for example, an oval or a nose or the like at at least one point of the circumference come into consideration as cross-sectional shapes.
  • the ringblindniet is rotationally fixed by positive engagement. It is sufficient if the fferblindniet is held against turning with the screw, a limited angle of rotation of sortedblindniets is harmless.
  • the fferably has a screw hole.
  • the fferblindniet has an engagement portion and a compression portion.
  • the screw hole has a smaller hole diameter, in
  • Upset section a larger hole diameter.
  • the engagement portion is a screw thread of the screw when it is screwed into the fferblindniet, in engagement with the SSblindniet.
  • the engagement portion can therefore be considered as a mother portion of synchronblindniets, wherein an internal thread does not have to be present in the engagement portion of fferblindniets from the beginning, but can be cut when screwing the screw from the screw thread.
  • the screw thread is not engaged with the fferdniet.
  • the screw is inserted into the threaded blind rivet by the swaging portion, i. it passes through the compression portion, and is or is screwed into the engagement portion.
  • a screw head of the screw is located on a side remote from the engagement portion of the upsetting portion, which is thus located between the screw head and the engagement portion.
  • Upset portion of the fferblindniets between the screw head and the engagement portion is clamped.
  • By screwing the screw and thereby causing movement of the engagement portion in the direction of the screw head of the compression portion is compressed and thereby forms a Nietwulst on the outside of the sortedblindniets.
  • Two sheets or other components, through which the fferblindniet has been previously inserted, are clamped between the Nietwulst and the screw head and are clamped against each other. They are connected by it.
  • a threaded pin with screwed nut is possible.
  • the fferdniet invention can be used instead of a sheet metal nut or a conventional blind rivet.
  • the sblindniet invention is preferably made of plastic.
  • the screw In the delivery state or at least in the ready-to-use state, the screw is inserted through the upsetting section into the ringblindniet and screwed into the engagement section, but the upsetting section is not yet compressed.
  • the fferblindniet is inserted in this embodiment of the invention with the already introduced screw through the components to be joined.
  • An embodiment of the invention provides for a constriction of the fferblindniets in the region of a transition from the compression portion to the engagement portion.
  • the constriction facilitates and / or supports the formation of Nietwulst, at least the initiation of the formation of Nietwulst.
  • An embodiment of the invention provides a reinforcement against expansion in the engagement portion of the fferblindniets.
  • the reinforcement may be, for example, a tubular metal ring or clamp that engages around the engagement portion and prevents it from expanding. Thereby, the screw thread is reliably held in engagement with the engagement portion of the fferblindniets.
  • an embodiment of the invention provides a swaging zone on a side remote from the engaging portion of the swaging portion. Stiffness against compression is greater in the compression zone than in the compression section. When the fferblindniet is set, the compression zone is in one or both to be connected
  • the compression zone is first compressed to form the rivet bead, ie the two components are clamped between the rivet bead and the screw head.
  • the compression zone allows yielding of the fferblindniets after riveting within the components, so that they tightened together by tightening the screw or firmer can be clamped together, even if the screw head rests on the fferblindniet.
  • An embodiment of the invention provides a collar of the fferblindniets, which rests upon insertion of the fferblindniets through the holes of the components to be connected on one of the two components and the fferblindniet thereby positioned on the one hand in the insertion direction of the components and on the other prevented falling through the fferblindniets.
  • the slip coating may be a conventional oil, grease or other lubricant. It reduces friction between the screw and the fferblindniet and thus also reduces the risk of co-rotation of the fferblindniets when turning the screw.
  • An embodiment of the invention provides a substantially massive rivet bead.
  • Conventional blind rivets in the form of hollow rivets usually form a hollow Nietwulst whose wall thickness corresponds to a wall thickness of the blind rivet. That has that
  • a solid Nietwulst can be achieved by the shape of the fferblindniets invention.

  • the screw head or, if present, a washer disposed below the screw head rests directly on a the engagement portion remote end side of synchronblindniets. This means that the screw compresses the fferblindniet immediately. It is not one of the components to be connected between the screw head and the end face of synchronblindniets.
