TOOL FOR MECHANICALLY MACHINING WORKPIECES

The invention relates to a tool for the mechanical processing of workpieces, in particular for the joining, self-piercing riveting or clinching of sheet, tube or profile parts, having tool-insert carriers which are movable relative to one another and to the working ends of which a respective tool insert of a tool set can be fastened, and having an electric-motor drive which acts on a plunger of at least one tool-insert carrier for performing a working stroke, the drive comprising as drive member a cam disk ( 21 ) which can be driven by a shaft ( 32 ) of a motor ( 31 ) and controls a positive motion of a stroke member which is formed by a rocker ( 16 ) which is pivotably mounted about a fixed axis ( 16.1 ) perpendicularly to a working stroke direction of the movable tool-insert carrier ( 1, 2 ) and whose free end ( 17 ) moves a plunger ( 9 ) guided in the working stroke direction.
