Abstract

1438669 Sub-press mechanisms US AMADA Ltd 4 July 1973 [10 July 1972 6 Nov 1972] 31937/73 Heading B3W A die set for punching holes in profiled structural members which have legs at right angles to each other comprises a C frame 10 having a punch 32 extending downwardly from an upper arm 11 sufficiently to allow one leg of the member W to be punched while another, or the other, leg extends upwardly on the side of the punch nearest the back of the C frame. The member W can be moved from this, broken line position, Fig. 1, to the full line position for punching the other leg by sliding it out of the frame 10, pivoting it clockwise and sliding it back under the punch. A punch guide 30 with a width "t" in the longitudinal direction of the C frame is over twice as wide transversely of the frame, to accommodate lifter springs (39) and stripper springs (44) Fig. 2 (not shown). In an embodiment for T-sections or the central lines of H-sections, Fig. 3 (not shown) the die is mounted on a pillar of the same dimension "t" in the longitudinal direction of the C frame as the punch guide.
