Abstract

1441097 Punch and die mountings E S JOSEPH 27 Dec 1972 [30 Dec 1971] 59722/72 Heading B3W In a pair of co-operating punch and die members, each member has screw threaded means for removably mounting it in a sheet metal working apparatus which mounting means are centrally disposed wholly within the periphery of the member when viewed axially. The punch and die pairs are particularly for use in a press for punching knockouts in sheet metal panels to be formed into, e.g. electrical junction boxes, their mountings enabling them to be placed close together. As shown in Fig. 1 each punch and die has a threaded recess to receive a bolt 66 by means of which it is securable to a template 61 or 62 respectively mounted on mechanicallyactuated platens 57, 58. A central spigot 67 on each punch and die engages a recess in the associated template. Punches 11-13 and dies 16-18 each have an anti-rotation locking pin 69. The spacing between pins 69 and bolts 66 is constant to allow interchange of tools. Punch and die pair 12, 17, for punching a central knockout surrounded by two concentric annular knockouts, comprises punch portions 21, 22 co-operating with apertures in the die 17 in which resilient stripper bodies 34, 36 are located. Relative rotation between punch portions 21 and 22 is prevented by a pin 29. Tabs 39 interconnecting the knockouts are formed by means of notches 40 in the punch portions 21, 22 and die portion 31. To form a central knockout with one concentric annular knockout the die portion 31 and punch portion 22 are omitted.
