Abstract

The tools has a cutting die and a cutting plate for the external contour; a punch for the internal contour; an ejector for the waste, and an ejector ring for the workpiece. The tting die (1) and the plate (2) each have a conical ring surface (4) to generate a hydrostatic pressure and a radial flow in the cutting plane of the external contour (3). - Located opposite to the punch (13) is a flow press die (7). This has a press cone, generating a hydrostatic pressure in the cutting plane of the internal contour (6), and flow-pressing the waste (21) to that contour.
