Abstract

1377434 Presses KOMBINAT UMFORMTECHNIK ERFURT VEB 15 Feb 1972 6981/72 Heading B5F A press comprises a ram 1 and an ejector device including an ejector pin 13 slidably mounted in the ram and connected through gear-wheels 11, 12 to a rack 3 also slidably mounted in the ram, a projection 2 on the rack and arranged to engage an abutment 4 on a pivoted lever 7 as the ram is retracted causing the rack to stop and thus the wheels 11, 12 to rotate to move the pin 13 outwardly, and a cam 14 adjustably mounted on the ram to strike the abutment 4 to pivot the lever 7 to release the rack. A spring 16 causes the rack and thus the pin to return to their initial positions.
