Abstract

327,010. Dietrich, E. March 26, 1929. Punching ; stamping.-In a machine for punching, cutting or stamping sheets, plungers 8 Carrying tools 18 work in tubular guides 7 mounted on a disc 1, and co-operate with dies 19 secured to a disc 2. Rotation of the discs for tool selection brings a slotted head 15 of the appropriate plunger under an actuating member moved by a lever 14. The dies 19 are mounted in the disc 2 by oppositely coned pins 21, which engage a groove in the die stem 20. The pins have screwed ends 23 by which the pins are moved axially to effect adjustment of the dies. The guides 7 are secured to the disc 1 by wedges 12. Plates 10 secured to the disc 1 carry detents 16 for holding the plungers on the raised position and co-operate with a cut away portion of the plunger to limit the upward movement.
