A reshaping device according to the invention has at least one ejector, for example, in the form of a cylinder pin (11) which is shifted by the workpiece (6) against the pressure from a pressure storing cylinder (17) or other suitable energy storing device before and/or during the reshaping of the workpiece (6). The workpiece ejection occurs by the work stored in the energy storing device.
