Definitions

  • This invention relates to a novel method of fastening sheet material by the use of a self-piercing rivet.
  • self-piercing is used in relation to rivets to define tubular, or part- tubular rivets which can be used to fasten together two or more sheets of material without the requirement for a preformed hole or holes through the sheets.
  • self-piercing rivets can be advantageously employed by virtue of their economy, and the high security fastening which they provide.
  • Sheet material can be produced by many methods, such as rolling, extruding or casting. When extruded or cast it can be produced integrally with an extruded or cast profile. It can be formed from a variety of materials, such as metals, plastics, wood or glass.
  • Conventional self-pierce riveting overcomes this problem by eliminating the need for pre-pierced or pre-drilled holes. It secures the sheet material by driving a rivet, using a rivet applicator, into the sheets of material at right angles to the plane of the sheets. As the rivet is forced into the two sheets it acts initially as a piercing punch so that a slug of material defined by the piercing of the material by the rivet lies within the hollow of the rivet. Thereafter the slug is driven forwardly with the rivet and the combined slug and rivet act as a drawing punch on the material in their path.
  • the riveting apparatus further includes a female die having therein a circular recess with a centrally disposed upstanding anvil, into which material displaced by the forward movement of the combined slug and rivet is drawn. As the displaced material reaches the anvil of the female die it is trapped between the advancing rivet and the anvil. Further forward movement of the rivet and slug causes the tubular portion of the rivet to roll radially outwardly. The tubular portion of the rivet is thus spread radially outwardly and the material displaced is shaped by the recess of the die.
  • a major drawback of conventional self-pierce riveting is that in order to have the strength to pierce the sheet material without collapse, the rivet size has to be far greater than that required to provide an effective fastening.
  • the normal mode of failure when a riveted joint is taken to destruction is for the sheet material to stretch until it is pulled clear of the rivet.
  • the rivet itself does not normally fail under functional load because the strength it requires to pierce its way into position within the sheet is greater than the strength required to resist the forces transferred to it by the sheet as the sheet reaches its yield point.
  • a further drawback of conventional self-pierce riveting is that it causes cracking of the displaced material of the lower sheet when the ductility of the lower sheet is low as with, say, cast or extruded aluminium. If a large rivet is required to pierce the materials concerned the volume displaced is also large and the stretching involved may take the displaced material beyond its yield point. Yet a further drawback of conventional self-pierce riveting is that it is limited in its ability to fasten thin material to the underside of thick material because a rivet which is strong enough to pierce the thick material is too strong to roll within a thin lower sheet.
  • the material may be removed from the upper or lower sheet by any of the conventional metal removing processes, i.e. by drilling and piercing. The removal may generate a hole, partly or fully, through the sheet;
  • the invention may be considered to provide, in one aspect, a method of joining two or more members at least one of which is a sheet material by means of self-pierce rivetting in which the combined thickness of the members is reduced at a region to be rivetted without creating a hole which extends through all of the members, self-piercing rivet is introduced at that region.
  • the rivet required for our novel method of fastening has unique features:
  • the upper sheet can provide side- ways support and this, combined with very effective anchoring achieved by the normal rolling action of the tube, provides a secure peg which can protrude any desired amount above the upper sheet.
  • Our novel method of fastening retains all the advantages of conventional self- piercing in terms of security of fastening, airtightness and watertightness, and is very versatile in terms of the materials which it can fasten. These include metal, plastic or composites, rolled-sheet, cast, extruded or moulded. It is also versatile in terms of the volume of material removed from the sheet. For instance a drilled hole may pass partly through the upper sheet or totally through it, and in some instances even pass into the lower sheet, whilst in all cases leaving enough material to effect a secure fastening.
  • Fig 1A shows two sheets of material 1 positioned above a setting die 2.
  • the top sheet of material 1 has a through-hole 3 to receive the shank of rivet 4 which is forced by plunger 5 through hole 3 into the lower sheet of material 1.
  • the material displaced from the lower sheet of material 1 is forced into cavity 6 of die 2.
  • Fig IB shows a sectional view of rivet 4 after being set within material 1.
  • Fig 2A shows material 7 the lower sheet of which has a partial hole 8 into which the material displaced when rivet 4 is set within material 7 can be contained to give a flush finish 9 on the lower sheet, as shown in Fig 2B.
  • Fig 3 A shows material 10 the upper sheet of which has a through-hole 11 to receive the shank of rivet 4, and the lower sheet of which has a partial hole 8.
  • the displaced material can be at least partially contained within hole 8 as shown in Fig 3B.
  • Fig 4 A shows material 12 the upper sheet of which has a partial hole 13 to receive head 14 of rivet 4 when rivet 3 is set within material 12, as shown in Fig 4B.
  • Fig 5 A shows material 15 in which the upper sheet has a 2-diameter through- hole 16 to receive the head and shank of rivet 4 when rivet 4 is set within material 15, as shown in Fig 5B.
  • Fig 6 A shows material 17 which consists of three sheets, the upper of which contains through-hole 18 into which the shank of rivet 4 can pass when being set within material 17, as shown in Fig 6B.
  • Fig 7 A shows material 19 which consists of three sheets with through-hole 20 in the upper two sheets and partial hole 21 in the lower sheet.
  • Fig 7B shows a sectional view of rivet 4 set within material 19.
