A hydraulic motor vertically displaces the upper part toward and away from the lower part. A punch having a lower punch end is vertically displaceable on the upper part between an upper rest position with the lower end above the lower surface of the upper part and a lower working position with the lower end below this lower surface. A die is provided on the lower part in vertical alignment with the punch so that the lower punch end can engage in the die when the punch is in the lower working position and the upper part is displaced town toward the lower part. A rivet anvil and an embossing tool are provided on the lower surface of the upper part adjacent the punch ant a rivet-setting tool has an upper tool end ant is vertically displaceable on the lower part between an upper working position with its upper end above the upper surface and a lower rest position with the upper tool end below the upper surface.
