  • Forming machine for forging, in particular, stretch-forging, workpieces
    Patent number: 9457393
    Abstract: A forming machine for forging metal workpieces which have been heated and/or are in a flowable condition including at least two forming tools (4A, 4B), at least one driving device for driving at least one of the forming tools in an approach motion (R) of the forming tools toward one another or in a return motion of the forming tools away from one another, and wherein the driving device comprises at least one eccentric element (22A, 22B) and at least one hydraulic drive element (11A, 11B), wherein the at least one hydraulic drive element (11A, 11B) is coupled hydraulically directly or indirectly to the eccentric element (22A, 22B) in such a way that an eccentric motion of the eccentric element produces a working motion of the hydraulic drive element by way of a hydraulic medium.
