ABSTRACT:
The machine comprises a work surface on which sheet metal rests, a fixed structure which supports the work surface, a work station provided with a hammer movable along a vertical axis to punch the sheet metal, punch units defined by a first holder and a punch tool, and die units defined by a second holder and a die tool. The machine includes a first rotatable table which carries the punch units and which transfers a punch unit to the work station, and a second rotatable table which carries the die units and which transfers a die unit to the work station. It includes a first structure for centering the punch unit with respect to the axis by securing the first holder to the fixed structure and means for centering the die unit with respect to the axis by securing the second holder to the fixed structure, excluding the tables from this securing which are therefore not affected by the mechanical stresses generated during punching, which are transmitted by the centering structure directly to the fixed structure.
