Abstract

1455276 Piercing; spinning J A VAN GEFFEN 17 Dec 1973 [15 Dec 1972] 58347/73 Headings B3H and B3J A rotary piercing tool is formed with a pair of polygonal cross-secion portions 14, 15 to form a wall 18 around a hole pierced in a metal plate 20 or in the wall of a tube and a third larger portion 4 is provided to shape the end face of the wall. The polygons have the margins of each face 17 curved 16 towards the apexes. The second portion 15 of the tool may be tapered or prismatic to form a cylindrical bush 22, Fig. 4. The tip 10 of the tool is non-cutting and during the high-speed rotation it generates friction heat in the metal plate or tube to facilitate deformation. The polygons may have three, four or more faces.
