Abstract

A forming tool for pressure forming a connecting web between incompletely separated workpiece parts of a plate-like workpiece from a cutting operation, in particular a metal sheet, comprises two tool parts, of which each is provided with a forming unit. The tool parts are able to move towards each other along a stroke axis with a processing stroke to a stroke end position. Each of the forming units has a forming surface on a web side facing away from the respective workpiece part, wherein the said forming surface, starting from a front face of the forming unit extends along the stroke axis away from a workpiece side facing the respective workpiece part.
