Abstract
1484607 Punching SIEMENS AG 12 Sept 1974 [28 Sept 1973] 39913/74 Heading B3W A punching machine comprises a carrier 1 for a punch (not shown), a die 7 and a punch guide plate 6 through which also pass a pilot pin 2 with a tapered end 22 for fine positioning of a punched tape, located in guides 9 on the die 7, as it enters a hole in the tape and a triggering pin 3 which, if it fails to enter a monitoring aperture in the tape, is moved upwards against the action of a spring 11 and displaces a pin 4 which, via a limit switch, stops the machine. The pins are displaceable relative to the punch carrier 1 but the maximum amount by which they can project from the lower face of the guide plate 6 is constant and is determined by engagement of shoulders 23, 33 with shoulders on the plate so that regrinding of the pins, when the punch and die are reground and the initial clearance between the guide plate 6 and carrier 1 is correspondingly reduced, is not needed. To the same end, a pin 8 for lifting the tape after each punching stroke is adjustably mounted in the die 7 by means of lock nuts 13, 14.
