Abstract

1385566 Cupping CYLINDER FORMING Ltd 22 May 1973 [19 June 1972] 28597/72 Heading B3Q Shock absorber bodies and other tubular components deep drawn on a punch 26 are given a smooth bore by a projecting rim on this punch as the latter is withdrawn from the components. Oppositely-directed punches on each side of a slide (14), Fig. 1 (not shown), co-operate with a die-set 12 at each end of the press, the slide being moved hydraulically and the punches supported in bearings (22). A tungstencarbide ring 48, secured to the punch by a screw or brazing, may provide a projecting rim constituted by frusto-conical and cylindrical surfaces 52, 54. Alternatively, the whole punch may be formed of hard material, the radiused corner 58 may be bevelled and the tapering section 52 may be replaced by a radial shoulder. The drawn component may be supported against expansion during withdrawal of the punch.
