Definitions

  • the present invention relates to a self-punching fastener, which in a way safe against rotation and pressing out can be pressed into a metal sheet having an annular body, the side of which facing the metal sheet is having radially positioned projections, which are pressed into the surface thereof during the setting in the centre of which an interior thread being provided and which on the side of the annular body facing the metal sheet in the set state is having a surrounding annular depression into which the metal sheet material displaced during the setting is pressed.
  • the present invention is based on the fact that for achieving an optimal safety against rotation burl-shaped locking elements are provided in a maximal distance to the central axis to make use of the most effective lever against the rotational momentum at the utmost supporting collar of the annular depression.
  • a further advantage of the solution according to the invention is consisting in the fact that by the above described displacing of the security against rotation and the inclined formation of the bottom of the annular depression at the innermost limit of the annular depression—the punching collar—there is more space for the penetration of the cutting ring of the punching die available, which means it is possible to work with larger thicknesses of the metal sheets or larger gauge ranges with the solution according to the invention.
  • the coordination between the punching die geometry and the shape of the annular depression and the kind of security against rotation according to the invention is ensuring that after the pressing-in of the metal sheet material a jamming on the punching die is prevented and therefore a high working safety is secured.
  • the shape of the projections or burls can be arched as well as with sharp edges (triangular).
  • FIG. 1 is showing a fastener according to the invention in the shape of a nut consisting of an annular basic body 10 .
  • a through-bore which at least over a part of the height of the fastener 10 is formed as a thread 11 .
  • the fastener 10 according to the invention is provided with an annular depression 12 , the bottom face of which starting from its inner limitation—the punching collar 13 —is inclined to its outer limitation, i.e. the supporting collar 14 .
  • annular depression 12 at the outer supporting collar 14 there are provided evenly distributed burl-shaped locking elements 15 in an annular array.
  • the punching collar 13 is having an undercut 16 towards the axis 20 of the fastener 10 according to the invention and the supporting collar 14 is having an undercut 17 in the direction of the exterior enveloping face 18 of the fastener 10 according to the invention.
  • the punching collar 13 is having a cutting edge 19 .
  • FIG. 2 shows the fastener 10 according to the invention of FIG. 1 in a bottom view.
  • the shape and the position of the burl-shaped locking elements 15 are clearly shown.
  • the burl-shaped locking elements 15 are positioned at the outer supporting collar 14 and are forming a free-space towards the punching collar 13 .
  • FIG. 2 the variant with annularly shaped burl-shaped locking elements 15 is shown.
  • FIG. 3 shows the fastener 10 according to the invention in an embodiment having sharp-edged (triangular) burl-shaped locking elements 25 .
  • FIG. 4 shows the fastener 10 according to the invention in accordance to FIG. 1, 2 and 3 as well as the punching die 30 and the metal sheet member 40 . From this representation it can be learnt that the metal sheet member 40 does not have a prefabricated hole and does not need any further preparation.
  • the punching die 30 is having a cutting edge 31 and a swaging ring 32 having a special geometry 33 .
  • the exterior enveloping face 34 of the swaging ring 32 is running conically towards the central axis 20 of the punching die 30 . This is ensuring that after the punching and pressing-in of the metal sheet member 40 into the annular depression 12 a jamming of the swaging ring 32 in the metal sheet member 40 is avoided.
  • FIG. 5 shows the fastener 10 according to the invention of FIGS. 1 to 3 shortly after the finalization of the setting procedure.
  • a disk 41 has been punched out of the metal sheet member 40 and the material of the metal sheet member 40 has been swaged into the annular depression 12 by the swaging ring 32 enclosing the burl-shaped locking elements 15 , 25 .
  • the stemmed out disk 41 is discarded downwardly from the punching die 30 .
  • FIG. 6 is showing the fastener 10 according to the invention completely set in a metal sheet member 40 .
  • the action of the undercut 16 , 17 at the punching collar 13 and at the supporting collar 14 is clearly shown.
  • the annular depression 12 is filled with the material of the metal sheet member 40 .
  • the burl-shaped locking elements 14 , 25 are embadded in the metal sheet member 40 .
  • the positive action of the bottom face of the annular depression 12 inclined to the exterior for enlarging the active length of the punching collar 13 and therefore for increasing the range of useable gauge ranges of the metal sheets for the fastener 10 according to the invention can be clearly noticed.
