Abstract
1352303 Stamping GREER PRODUCTS Inc 28 Feb 1967 9581/67 Heading B3Q In a metal forming process a cavity die receives a metal sheet pressed into it by a lead ram. As the lead is urged into the cavity it extrudes over the surface and rolls the metal sheet against the die surface. Aluminium or an aluminium alloy may replace the lead. The lead ram 26 may have a steel core, 24, to prevent pressure being applied to the central area of the sheet workpiece 31, until the final stage of the process. A pressure-sensitive contact switch 36, between the steel core and the sheet maintains contact between the two. The ring 20, serves as a guide for the ram, 26, as it is urged into the die cavity, 12, by the ram, 28. As the lead advances, the workpiece, 31, is rolled against the die side wall.
