Abstract

1403823 Seaming; shearing blades; cutting and bending dies; making tubes and handles W M CARROLL 10 Oct 1973 47396/73 Headings B3J B3W B3E and B3A A sheet metal tube or a pair of metal plates is seamed by interfitting mating recesses 22 and projections 20 and coining the centre of each projection to cause radial flow of the projection into tight engagement with the recess. The tube blank is sheared from metal stock 40, Fig. 4, by shears 45, 48 and bent around a mandrel 50 by dies 44, 54. The tubular blank is then moved axially along the mandrel to a position where the projections are coined by punches 62 on a die 60. The tube may be used as a spacer or flame guard (14), Fig. 5 (not shown) for a saucepan. The metal may be aluminium or copper.
