Abstract

An improved mechanism for automatically clamping a die tool to a press bed or press ram. The automatic die clamp is self-locking and self-compensating to provide a failsafe operation in the clamped position and thus the mechanism retains the clamp in the clamped position. A ramp is provided to guide the movement of a wedge which wedge movement controls the movement of a clamping member. A spring bias may be provided as an optional feature to assist in the self-locking. Release of the clamp requires the application of an external force to overcome the locking of the teeth.
