Definitions

  • the innovation relates to a punch-embossed rivet according to the preamble of claim 1.
  • Stamped-embossed rivets are used to connect two flat workpieces.
  • the punch rivet is here with the formation of two punch holes with its shaft through the workpieces pressed.
  • the lower workpiece seen in the punching direction consists of a plastic deformable material, usually a sheet. Near the end of the shaft the Shank a shaft groove. After the punching process, around the end of the shaft the lower workpiece is shaped by an annular groove tool, which makes the material of the lower workpiece is pressed into the shaft groove.
  • the shank groove has a trapezoidal shape in cross section.
  • the upper workpiece consists of one soft material, such as a soft sheet or plastic, then material is sheared from the upper workpiece by the upper edge of the shank groove and pressed into the shaft groove. As a result, the material intake volume for the Lower workpiece material reduced, creating a poor riveted joint is effected. If the upper workpiece is made of plastic, it can be used as a whole Filling the shaft groove with plastic come so that the rivet connection does not is useful.
  • the punch rivets are manufactured as turned parts.
  • a punch-emboss rivet according to the preamble of claim 1 is known from DE-U-297 07 669.
  • the first factor is that the shaft groove overall and should only be filled with material from the lower workpiece.
  • the second factor is the angle at which the section facing the shaft end of the Shaft groove runs. An ideal approach would be to approximate an angle of 90 ° however, the risk of breakage mentioned above is significantly increased.
  • the task is to design the rivet so that the strength of the rivet connection is increased without the disadvantages mentioned above occurring.
  • the stamped embossed rivet is designated 1 in its entirety.
  • the one made with it Rivet connection connects an upper sheet metal part 2 with a lower sheet metal part 3.
  • the rivet 1 has a truncated cone-shaped rivet head 4 and an adjoining one Shank 5 on
  • the shaft 5 is provided with a shaft groove 6, which is downward a cylindrical section 7 of the shaft 5 connects.
  • the rivet is passed through from top to bottom Sheet metal parts 2, 3 pressed, which in the sheet metal parts 2, 3 aligned with each other Punch holes are created.
  • a ring-shaped tool around the section 7 around a groove 8 whereby is caused that material of the lower plate 3 with plastic deformation in the Shaft groove 6 is pressed and fills it.
  • This shaft groove 6 is concave, but has a circular shape deviating shape, which approximately corresponds to a drop shape.
  • the section 10 of the annular groove 6 facing the rivet head 4 runs relatively below one flat angle ⁇ to the axis 11 of the rivet 1.
  • Section 12 of the annular groove 6 extends at an angle ⁇ to the axis 11, which is larger than 90 °.
  • the inclination of the section 10 thus corresponds to the angle ⁇ , while the Inclination of section 12 corresponds to the angle 180 ° - ⁇ .
  • This supplementary angle is in any case larger than the angle ⁇ .
  • the annular groove has a rounding 13 between the two sections 10, 12.
  • the Transition between section 10 and shaft 5 can also be rounded, during the transition from section 12 of annular groove 6 to section 7 of shaft 5 can be formed with sharp edges.
  • the relatively steep course of section 12 of the groove 6 is for the strength of the riveted joint is of decisive influence.
  • the angle ⁇ is larger than 90 ° and the more it approaches this value, the higher the resulting one Strength of the riveted joint.
  • the limit of the angle ⁇ is primarily determined by the hardness of the material of the sheet 3. It should be chosen so that no breakage of the rivet shaft occurs in the area of the groove 6.
