An upper tool support (4) for a stamping machine or the like has at least one or several stamping tools (5) adjacently located. Each stamping tool (5) has a punch (7) a punch support (8) and a retaining nut (9) connecting the punch (7), with the punch support (8). The upper tool support (4) is provided with a support body (10), and a receiving plate (11) with a tool guide (12) for each stamping tool (5) extending in the direction of stamping. the upper end of the stamping tool (5) is limited to move in the stamping direction by support flanges (15), being thus guided in the direction of stamping. A receptacle (17) for the upper end of each stamping tool (5) is provided in the support body (10), above the tool guide (12) and below a power transfer area (16). The receptacle (17) is bridged by means of a power transfer rod (18) which is generally movable in a direction perpendicular to the stamping direction. A lifting lever (20) is provided on the support body (10) associated with each stamping tool (5). each lifting lever 20 laterally engages the upper end of the associated stamping tool (5) from below. The upper end of the stamping tool (5) is actively liftable into the receptacle …
