Abstract

1322682 Punching J E L E MEMAIN 11 Jan 1972 [12 Jan 1971] 1309/72 Heading B3W A punching machine includes a C-frame 4, for supporting a tool carrier 2 and die 3, which is pivotable on a base about the axis of the tools and has means for immobilizing the C-frame in a selected angular position. A pin 9 on the base 10 of the frame is engageable in a selected one of holes 8 around the circumference of a table 7 and the frame runs on wheels 11. A workholder 12 is mounted on a feed table 1 for movement in directions F and F1 manually or automatically using an electronically-programmed control system. By rotating the C-frame through selected angles between punching operations on a stationary workpiece, holes of different shape from that of the punch may be formed.
