ABSTRACT:
A die clamp arrangement for a press has a clamping lever that is shifted horizontally by a dog between an extended and a retracted position and rotated in a vertical plane between a clamping position and a released position. The cam and dog are interconnected for rotation in unison by a single shaft. In the retracted position the clamping lever is adapted to permit vertical movement of a die into and out of a press. Means are provided for actuating the clamps at the rear and at each side of the die from the front side of the press. The clamps at the front and/or the rear sides of the press are arranged to be pivoted from an operative position downwardly to an out-of the-way position below the top face of the press bolster.
