Abstract
In a multistage forming machine, an apron is screwed to a press slide. At its upper end, the apron has six elongated clamping cams, distributed over its width, while four upwardly projecting clamping lugs are fitted at is lower end. Suspended in the apron is a combined tool block with a wedge-shaped supporting plate. Four clamping lugs, distributed over the width, are formed at the upper end of the supporting plate, while four clamping cams are formed at the lower end. The clamping lugs of the combined tool block are suspended by means of the clamping cams of the apron, while the clamping cams of the combined tool block are inserted between the clamping lugs and the main part of the apron. By means of two clamping devices, a clamping force acting in the vertical direction of the combined tool block is produced, bringing about a clamping of the combine tool block and the press slide in the horizontal direction.
