Patent ID: 8297098

Claim:
A ram assembly for a turret machine with a turret axis, comprising: a frame member; a first ram with a first cam follower bracket and a first set of cam followers; an outer die tooling connected to the first ram; a second ram with a second cam follower bracket and second set of cam followers; an inner knockout tooling connected to the second ram; a first cam surface, the first set of cam followers configured to follow the first cam surface; a second cam surface, the second set of cam followers configured to follow the second cam surface; and an anti-lift device configured in relation to the turret machine to resist lifting of the ram assembly away from the turret axis in a radial direction, thereby resisting a sliding of the first and second set of cam followers laterally along the first and second cam surfaces away from the turret axis, wherein the first ram is connected to the second ram on the frame member, wherein as the first set of cam followers follows the first cam surface, the outer die tooling moves toward or away from an article to be worked on, and wherein as the second set of cam followers follows the second cam surface, the inner knockout tooling moves toward or away from the article to be worked on, and wherein the anti-lift device includes a first anti-lift roller positioned against the first cam follower bracket.
