Definitions

  • the cavity has an approximately cylindrical outer wall in the periphery thereof.
  • the upper end of the outer wall has a bevel or a radius which is very small.
  • the outer wall of the cavity has an upper end having an inner diameter of:
  • the present invention is related to such a self-piercing rivet setting apparatus.
  • Fig. 1 is a sectional view showing connected workpieces with a self- piercing rivet driven by a conventional setting apparatus.
  • the material of the workpieces flows outward by the central raised portion 29 toward the outer wall 27 through the bottom 35 of the cavity, and further flows upward along the outer wall 27 after changes its direction smoothly.
  • Fig. 4 shows the die 18' according to the second embodiment of the present invention.
  • the outer wall 27' has the upper portion which has a smaller diameter than the lower portion.
  • the second embodiment is similar to the first embodiment.
  • the receiving-side workpiece adjacent to the die has a squeezed configuration in the upper part of the cavity, and thus the workpieces are connected more reliably than the first embodiment.
  • Fig. 5 is a sectional view illustrating the state when the workpieces 2 and
  • the workpieces are pressed by the rivet from above direction. Also, by the rivet-driving operation, a portion of the workpieces that contacts to the periphery of the cavity of the die is crushed between the rivet and the die and work hardened (the H portion). Therefore, the material of the workpieces that has flowed upward along the outer wall 27 cannot move further upward, and thus flows in the direction toward the center of the cavity 25 (the II direction). As a result, the receiving-side workpiece will have a squeezed configuration in the upper part of the cavity, creating a protrusion 8 to form the undercut U.
  • the outer wall 27 has the upper inner diameter D which is not too large compared with the outer diameter of the leg of the rivet.
  • FIG. 9 is a sectional view illustrating the state where the workpieces 2 and 3 are connected by the self-piercing rivet 1 using the die 18 according to the present invention.
  • Example 1 due to the shape of the cavity 25 of the die 18, the material of the workpieces flows well within the cavity 25.
  • the receiving- side workpiece 3 has the squeezed configuration in the upper part of the cavity thereby creating the undercut, and thus the workpieces are reliably connected. As a result, the thick workpiece 2 and the thin receiving-side workpiece 3 are not easily separated. (Comparison 2)
  • the workpieces when the workpieces are connected by the self- piercing rivet using the die according to the present invention, a smooth flow of the material of the workpieces can be formed upon connecting the workpieces, and as a result the receiving-side workpiece has the squeezed configuration in the upper part of the cavity, thereby creating the undercut. Therefore, the workpieces can be connected more reliably than the case where the self- piercing rivet connects the workpieces using the conventional die.
  • the receiving-side workpiece is thinner than the punch-side workpiece or when more than two workpieces are connected, even in such cases, a plurality of workpieces can be connected reliably.

Abstract

Cette invention concerne une matrice (18) à utiliser avec un appareil de pose pour rivets auto-perforants. Cette matrice comprend une cavité (25) destinée à recevoir une région saillante de la pièce, qui comprend les parties respectives des pièces (2, 3) devant être repoussées en saillie vers la matrice sous l'effet de la pression du rivet auto-perforant (1). La cavité présente une surface inférieure à partie centrale surélevée en direction d'un poinçon. Cette partie centrale surélevée fait un angle vertical compris entre 90 et 160 °. Sa partie supérieure est de préférence de forme sphérique. La cavité possède une paroi extérieure approximativement cylindrique (27) à sa périphérie et une surface intérieure incurvée allant du haut de la partie centrale surélevée au bas (33) de la paroi extérieure en passant par le fond (35) de la cavité.
