Abstract
A tool-clamping device for a forming tool, in particular a bending punch or bending die, on a compression beam, in particular an edging press, comprising a tool adapter attached to the compression beam and designed to releasably hold the forming tool. At least one resiliently elastic return means is provided between a receiving region of the tool adapter and a connecting region of the tool adapter or between the beam and the tool adapter to counteract a relative displacement between the tool adapter and forming tool and the compression beam in the longitudinal direction of the beam.
