Abstract
1. Punching tool for punching out of rotationally symmetric hollow bodies from square plates, which tool is provided with a drawing die (5) and a drawing stamp (7) having a differential clamping device (8) consisting of a thrust ring and axially displaceable segments arranged diagonally of one another in the ring and having a relatively strong contact pressure, characterized in that a simultaneous punching tool is formed by additional provision of a punching tool (2, 3) consisting of two stamps (2) opposed in the movement direction of the material strip (a) and two associated dies (3) for punching out respective ones of two opposed triangular cutouts (b) on the sides of the material strip (a) and provision of a separation tool (6, 9) arranged in the movement direction of the material strip between the punching tool (2, 3) and the drawing die (5) or as the case may be the drawing stamp (7) for the separation of the most forward plate of the material strip (a).
