Abstract

1303234 Forming rivets in sheet material; riveting ALUMINUM CO OF AMERICA 19 April 1971 [18 March 1970] 23776/71 Headings B3A and B3U A method of forming an integral rivet in a sheet element 2 comprises placing the sheet element between male and female dies 4, 6, moving the dies together to form a hollow boss, continuing movement of the male die cornpressively thins an annular portion 50 of a lower sector of said hollow boss by establishing metal flow substantially entirely in the direction of the upper extremity of the hollow boss so that this part of the hollow boss is substantially equal to the thickness of the remainder of the sheet material and subsequently forming the hollow boss to establish a hollow rivet. To form the rivet the hollow boss is placed between male die 62 and female die 70, which when moved together form a rivet 60 with the annular thinned portion forming no part of the rivet. The sheet element may be adapted to serve as a container wall in which case a tab element 90 may be required to be attached to the rivet. A staking anvil 92 and a staking punch 102 surrounded by a relatively movable pressure pad 98 are utilized to do this. Anvil 92 has a boss 96, an upper annular surface 108 and a lower annular surface 110. The tab and sheet 2 are clamped as shown in Fig. 11, and the swaging panels moved to form rivet head 104. The clamping serves to restrict the amount of flow in the sheet outwardly and avoids thinning of the rivet during staking. Some minor flow occurs and undersurface 116 of sheet element 2 tends to assume a generally uniform thickness. The join between boss 96 and surface 108 is curved with a radius of between 0À010 to 0À030 inche. Male die 4 has a convex sheet contacting surface 16 having a compound radius, see, Fig. 9 (not shown).
