Abstract
1433826 Making fasteners; rolling LAMSON & SESSIONS CO 10 July 1973 [2 Aug 1972] 32943/73 Headings B3A and B3M [Also in Division F2] Circumferentially spaced surfaces are formed on a workpiece, e.g. a self staking fastener, by rolling the workpiece in contact with a tool having corresponding circumferentially spaced arcuate segments. In an example, a self-staking insert 10, Fig. 1, which punches its own hole in a sheet to which it is attached, is formed with surfaces 24 around its head portion 14 by an embossing roll 46, Fig. 3. The head is initially shaped from hollow bar stock 30 to have a frustoconical surface 78, and is spaced from a groove 64 cut with a tool 120. The roll 46 is moved radially towards the head during rotation of the stock by a chuck 28. A toothed wheel 48 coupled to the roll engages the base of the groove to cause rotation of the wheel and roll. The roll surface, Fig. 8, has arcuate portions 52 which form the surfaces 24 on the insert. The portions 52 may be shaped to produce flat, concave, or convex surfaces 24. After the shaping step, a cutter 116 chamfers the edge of the head 14, and the tool 120 partsoff the insert from the stock. The insert is then reamed and optionally provided with an internal thread.
