  • parts to be joined are referred to for convenience as plates if they are plate-like in the regions where they are superimposed and joined by the method of the invention.
  • the parts to be joined may, for example, be components of a motor vehicle seat.
  • a first metal plate 10 illustrated in section in Figure 2
  • a projection or boss 14 on one side, for example by a pressing operation, not illustrated, in which a corresponding depression or hollow is formed in the reverse side of the plate 10.
  • the projection or boss 14 is preferably, or at least typically, circular as viewed in a direction perpendicular to the planes of the major surfaces of the plate 10 and the central axis of the boss 14 is shown at A in Figure 2.
  • the boss 14 may, if desired, have any shape as viewed along the axis A.
  • the peripheral wall 18 of the boss 14 flares outwardly in a direction away from the body of the plate 10, i.e. in an upward direction as shown in Figure 2, so that the boss 14 is wider at its termination remote from the body of the plate 10 than it is where it meets the body of the plate and is thus of undercut or dovetail form.
  • the second metal plate 12, as shown in Figure 1 is formed with a through hole 20, with a peripheral wall 22 which is perpendicular to the planes of the major surfaces of the plate 12 and, as viewed in a direction perpendicular to these planes, is complementary in shape and size with the widest part of boss 14.
  • the boss 14 is circular, the wall 22 of hole 20, is a cylinder with axis A, and the hole 20 is of uniform diameter throughout, such that the boss 14 can pass into the hole 20 when the plates 10 and 12 are brought together.
  • the boss 14 is inserted through the hole 20 in the plate 12 of Figure 1 after which the material of the plate 12 is deformed or upset immediately adjacent the hole 20 so that, as shown in Figure 3, the material of the plate spreads inwardly, towards the centre of the hole, to occupy the undercut region around the boss 14. That is to say, in the finally formed joint, the hole has a flaring peripheral shape engaging and entirely complementary with the external periphery of the boss.
  • Figure 4 illustrates one way of forming the boss 14 in plate 10 of Figure 2.
  • a plate blank is pressed between a first press member having a projection 32 and a second press member 34 with a die 36 in which is formed a die opening with a peripheral wall which increases in diameter somewhat with distance away from the surface of the die 36 which directly opposes the first press member 30, that is to say the die cavity is undercut somewhat.
  • a first phase of the pressing operation as illustrated in the left-hand side of Figure 4, as the press member 30 is forced towards the press member 34, the material of the plate 10 under the projection 32 is caused to flow into the die cavity - is effectively extruded into the die cavity - to form a boss 14 within the die cavity which boss has at least initially a generally cylindrical outer surface which is in contact with the peripheral wall of the die opening at the upper outer end of the die opening but is spaced radially inward from that peripheral surface at the bottom of the die.
  • a counter punch 38 extending within the die 36 is then forced upwardly, as illustrated in the right hand side of Figure 4, to engage the end of the boss within the die, thereby deforming the boss to expand the latter at its free (lower) end, so that the boss assumes the desired tapering or flaring form.
  • the die 36 may be solid with a bottom surface of the die cavity corresponding to the upper surface of the counter punch in Figure 4, so that after the free end of the boss meets the bottom of the die cavity, further movement of the press member 30 towards the press member 34 forces the material of the boss to spread outwardly into the undercut portion of the die cavity.
  • the material of plate 10 is preferably significantly harder than that of plate 12 at the time the plates 10 and 12 are joined together.
  • the operation described with reference to Figure 4 may be carried out when the material of the plate 10 is relatively soft, e.g. before a hardening process is supplied to the plates or in a hot forging operation, with the plate being hardened after the boss 14 has been fully formed.
  • the die 36 is, of course, split longitudinally, e.g. along the vertical line A in Figure 4, to allow subsequent extraction of the boss 14 from the die cavity.
  • the deformation of the material of the second plate 12 around the hole 20, once the boss 14 has been projected through the hole 20 and the plates 10,12 brought together, as illustrated in Figure 3, may be effected in various ways.
  • the two plates may simply be brought together between opposing press members one of which is formed with an annular ridge or the like which engages the border region of the second plate around the hole 20 and deforms the material of the second plate to cause it to flow into the undercut region around the boss 14.
  • a die 40 which is rolled around the annular region around the periphery of the hole 20, as illustrated in Figures 7, 8 and 9 may be used to effect such deformation.
  • the die 40 used has a rotational symmetry about an axis B which is inclined at an angle relative to the normal to central axis A of the hole 20 and the boss 14, (the axis A being normal to the planes of the plate-like elements being joined), the movement of the die 40 being such that the axis B is rotated around the axis A as the die 40 rolls around the edge region of the hole 20.
  • the operative face of the die 40 provides an annular rib which forms a corresponding indentation in the co-operating surface of the upper plate 12 whilst at the same time causing the material of the upper plate to flow into the undercut region defined around the boss 14 in the lower plate.
  • the upper plate 12 is pre-formed with a raised annular area 42 around the hole 20 which receives the boss 14 of the lower plate, and the die 40, by flattening or partially flattening this raised area 42, forces the material of the upper plate 12 into the undercut region around the boss 14.
  • the die 40 operates in substantially the same way as in the arrangement of Figure 7, but the embodiment illustrated in Figure 9 differs from that of Figure 7 in that the upper plate 12 is not pre-formed with a hole to receive the boss 14 in the lower plate 10, but merely has a recess in its underside which receives that boss and which may, typically, be formed by a pressing operation between appropriately shaped press members engaging the upper plate 12 and the lower plate 10 and which leaves only the upsetting of the upper plate 12, to cause the material thereof to flow into the undercut region around the boss 14, to be effected by the die 40.
  • Figures 10 to 13 illustrate a variant method in which the plate 12 formed with the hole 20 is preformed in such a way that the peripheral wall 43 of the hole is flared or expands in width with distance away from the plate 10 to which the plate 12 is to be attached and in which the plate 10 is deformed to provide a boss 14 which is extended through that hole 20 and is subsequently upset to occupy the undercut region of the hole.
  • FIG 10 there is shown, to the left-hand side of the centre line A, (which, as in the other embodiments, is perpendicular to the planes of plates 10,12), an initial position in which the lower plate 12 with a preformed hole 20 is supported on a press member 44 which has a through passage 46 aligned with the hole 20 and within which passage 46 is vertically moveable a punch member 48.
  • the plate 12 with the hole 20 is of significantly harder material than the plate 10, and may, for example, have been subjected to a hardening operation after forming the hole 20 and, of course, before plate 12 is placed on the press member 44.
  • the plate 10 to be secured to the plate 12 is illustrated as being initially flat and planar in the region of the intended attachment to the plate 12 (as also shown in Figure 12), and is engaged on its upper surface by a press member 52 within which is mounted, for vertical movement in a vertical passage in the member 52, a punch member 54 with a cross-sectional shape corresponding to that of the hole 20 and the passage 46, but somewhat larger in diameter than the hole 20 and passage 46.
  • the punch member 54 is forced downwardly against the plate 10 causing the region of plate 10 over the hole 20 to be, in effect, extruded through the hole 20 until the lower surface of the extruded portion is substantially in the same plane as the lower surface of the plate 20.
  • the extruded portion thus forms the desired projection or boss 14 within the hole 20.
  • the peripheral wall of this boss 14 is substantially perpendicular to the major planes of the plates 10,12 so that the opposing peripheral surface 43 the hole 20 is spaced progressively further from the opposing peripheral surface of the boss 14 with increasing distance away from the major planes of the plate 10 and towards the underside of the plate 12.
  • the plate 12 may be formed with an undercut recess in its upper surface, instead of a through hole and the boss 14 may, after being drawn or extruded into this recess, be caused to spread laterally to fill the undercut simply by continued pressure resulting from continued advancement of the press members 52,44 towards one another.
  • the upper plate 10 is preformed with a boss 14 having an undercut or flaring peripheral surface and which boss 14 is effectively used as a punch to punch a complementary hole in the lower plate 12.
  • the material of the upper plate 10 is made significantly harder than that of the lower plate 12.
  • the superimposed plates 10, 12 to be joined are again located between opposing press members, referenced 52 and 44 in Figures 14 to 16.
  • the upper plate 10 is located on the underside of upper press member 52 which has locating formations, (shown as projections 53, 55), which engage complementary locating formations (shown as recesses), on the upper side of the plate 10.
  • the lower plate 12 is suitably located on the lower press member 44, for example by locating pins, one of which is illustrated at 60, engaging in complementary holes in plate 12.
  • the upper plate 10 is additionally provided with a locating projection or stub 62 aligned with the pin 60 and the hole in plate 12 which receives pin 60.
  • the press member 44 is provided with a die opening 46 complementary in size and shape with and directly opposing the boss 14 of plate 10 and accordingly, when the press members 44 and 52 are brought together as illustrated in Figure 15, the boss 14 punches from the plate 12 a piece 64, which exits through the die opening 46 in press member 44 and at the same time the boss occupies the resulting hole in the plate 12.
  • the locating projection 62 on the plate 10 enters the locating hole in the plate 12, the pin 60 moving down in the press member 44 to make way for projection 62.
  • the peripheral wall of the hole punched in the plate 12 is again substantially perpendicular to the major faces of the plate 12 and thus does not yet occupy the undercut region around the boss 14.
  • annular ridge or collar which up to this point, (as shown in Figures 14 and 15), has effectively supported the plate 12 by engagement with the underside thereof, the neighbouring regions of the plate 12 having their undersurface thus spaced from the remainder of the upper surface of the press member 44.
  • annular collar around the die opening is forced into the underside of the plate 12 upsetting the material of the plate 12 to cause this material to flow into the undercut region around the periphery of the boss 14, again to secure a firm joint.
  • the locating projection or stub 62 may be tapered conically slightly, at least adjacent its free end, to ensure its ready entry into the opposing hole in plate 12. It will be understood that, typically, the plate 10 may have a plurality of locating projections or stubs 62 and the plate 12 may have corresponding holes to receive the same, to ensure that the plates to be joined are correctly located with respect to each other. Such locating projections and complementary holes to receive the same may be provided on the plates to be joined in the arrangements described with reference to Figures 1 to 13 also, of course. The locating projections need not be on the same plate as the boss 14 or the complementary holes in the same plate as the plates with the hole which receives the boss. Of course any of various other ways of locating the plates 10, 12 to be joined prior to and during the pressing and upsetting or riveting operations may be used.
