Device for forging hollow component e.g. pipe, has control unit that controls rotary drive element in dependence on rotational position of forging mandrel with respect to forging tools that are arranged symmetrically about forging axis

摘要

A hollow component (3) has forging tools (2) that are arranged symmetrically about a forging axis, and are driven by radial strokes. A rotatably mounted mandrel rod (5) is arranged corresponding to a forging mandrel (4), and is engaged with a rotary drive element (10). The rotary drive element is controlled via a control unit (11) in dependence on the rotational position of the forging mandrel with respect to the forging tools.
