Definitions

  • the invention is based on a tool for rivet-like Joining panels or panel sections lying on top of each other (Clinching, or the like.) Or of plates with connecting parts (Punch rivets, bolt connection, or the like.) According to the genus of Main claim.
  • the tool according to the invention with the characteristic Features of the main claim has the advantage that apart from the fact that there is no clinching of the plates, i.e. through the connection point does not leak, that Tool according to the invention for clinching method application can find, where due to the symmetrical to the central axis Arrangement and in particular through the use of more than two movable jacket parts a controlled flow of the repressed Plate material takes place.
  • an extremely good connection point through this tool is producible, there is the advantage of extremely cheap production and last but not least the advantage of insensitivity and light Mountability of the tool.
  • the individual connecting sections While at the cross or star-shaped formation the individual connecting sections cross, or at least can cross, branches at the annular formation the individual springs radially from this ring from. So it is not an encompassing jacket-shaped Ring, but around one arranged in the parting plane of the die Disc.
  • the Bend a minimum radius of 10 percent of the Die diameter.
  • the durability and also the effectiveness of a leaf spring greatly depends on its design on the Clamping point dependent, with kinks easier Penetrations lead, in contrast to minimum radii.
  • Die bottom formed as a bearing body in which the jacket parts are stored and guided and at its, facing away from the stamp Side, the connecting sections of the individual springs support.
  • Sheath parts with the free ends of the individual springs cannot be detached connected. These jacket parts are based, for example Generation of the counterforce of the joining force caused by the stamp on the side of the die base facing away from the stamp. When evading, they then slide radially on this base part outside, each against the force of a single spring.
  • the jacket parts are attached to these sections Solder or weld on.
  • the free ends of the individual springs are pointing inwards Work opening kinked and serve in the direction of the stamp facing surfaces of the kinked sections of the individual springs Support for the jacket parts attached there.
  • This can relatively narrow areas of recording accordingly serve wide jacket parts, especially if these jacket parts in limit the total radial opening.
  • the division plane runs between the bottom part and one of the Base part serving in a machine tool, as indicated above, a completely self-contained tool arises.
  • the working opening distributes several sections of the boundary walls fixed, with the intermediate sections as the avoidable parts are formed. This allows the Jacket parts either completely cover the radial wall of the working opening form or they can form parts of the same while other parts stand still, depending on the desired design of the Connection node.
  • the radial path of the evacuable jacket parts through stops of Relentlessly limited die ensures that displaced material a cold compression and thus a the strength of the Connection point experiences significantly increasing hardness quality.
  • the stamp in the form of a rivet, a nut or a bolt trained to after enforcement has ended positive and / or non-positive in the effect caused by it Thermoforming opening to remain.
  • This material composite creates an additional strength of the connection mainly because the Thermoformed opening is filled in positively and a decoupling of the Connection point is no longer possible.
  • the base part 1 With the base part 1 is a base part 9 by means not shown connected, which the grooves 8, in which the connecting portion 7th is arranged, covers.
  • the spring device in the Held matrix and a completely and in itself arises closed tool, the dimensions of which the Machine tool in which it can be used for use can, is adjusted.
  • the bottom part of the die is according to the invention in a corresponding recess 17 of the Base part 9 pressed in after inserting the spring 6/7.
  • the jacket parts 2 are also in fixed sections for their Evasive movement, these sections 18 in Direction punch 4 to the die bottom part 1 or base part 9 connect. Stops 19 are also arranged on the base part 9, over which the escape path of the jacket parts 2 is limited, so that when Manufacturing process and with the corresponding displacement of Workpiece material when the shell parts 2 hit it Stops 19 and continue the stroke movement of the punch 4 a corresponding cold deformation of the material now crushed takes place.
  • 2 and 3 is a simple, cross-forming spring arrangement shown, namely with a cross-shaped connecting section 7 and the individual springs 6 arranged on the latter, the individual springs 6 in the drive direction of the stamp compared to the Connection section 7 have crankings 13.
  • This The spring arrangement is used to actuate four with four individual springs Coat parts. According to the number of shell parts is also then the number of free springs, so that the connecting section takes place can be designed as a cross, as a star.
