Abstract
A forging apparatus is described, comprising forging tools (5) which are arranged in a centrically symmetrical way about a forging axis (2) and whose tool holders (4) radially guided in a frame (3) are connected with lifting drives (7), which each comprise one respective connecting rod (8) that is pivotably supported via abutments (9) on a housing (1) on the one hand and on the tool holder (4) on the other hand, and comprising a common drive for the lifting drives (7) which comprises a torsional vibration drive (11) for at least one actuator (12) for the one of the two abutments (9, 10) of the connecting rods (8), which actuator is rotatably held about the forging axis (2). In order to ensure advantageous constructional conditions, it is proposed that the frame (3) forms the actuator (12) of the common drive for the lifting drives (7), and that the torsional vibration drive (11) is provided between the housing (1) and the frame (3) which is rotatably held about the forging axis (2).
