Die stamping and punching tool

A die stamping and punching tool machine comprising an upper press part;

• a tool plate carried by said upper press part;
• a lower press part including a rollable stamping table and a counter-pressure plate with a rolling profile;
• first and second toggle lever means for supporting said lower press part, each of said toggle lever means having a portion independently movable toward and away from a machine centerline to raise and lower an end of said lower press part relative to said upper press part;
• first and second cam disks rotatably mounted adjacent said independently movable portions of said first and second toggle lever means, respectively, for acting against said movable portions to control the movement of said lower press part,
• said cam disks having cam shapes selected to move the respective ends of said lower press part and thereby cause a desired rolling movement pattern of said stamping table including a portion shaped to cause substantially linear movement of said table with time during a stamping phase of said movement;
• drive means for driving said cam disks in synchronism with each other so that predetermined portions of said cam shapes act against said movable portions of said toggle lever means concurrently;
• a stamping table guide slidably engaging said stamping table for guiding the motion thereof;
• and
• a third cam disk operatively associated with said table guide for controlling the motion of said guide.
