A rotary-draw bending die with eccentric clamping for bending elongate workpieces such as pipes, wires, profile strands, etc. The die having a twistable bending mandrel, and an associated clamp die. The clamp die can be moved relative to the bending mandrel and brought from an opened position remote from the bending mandrel. A workpiece to be bent can be inserted between the bending mandrel and clamp die to a clamping position on the bending mandrel or vice-versa and is freely twistable about a swivel axis which is offset eccentrically in relation to the rotational axis of the bending mandrel. The swivel axis is disposed on a rotary plate which is rotatable relative to the bending mandrel. The clamp die is freely twistable about the swivel axis and can be moved between its clamping position and its opened position by twisting the rotary plate relative to the bending mandrel.
