摘要：
In a multi-stage forming machine, a die-change device, for male dies in a male-die block has a mounting plate for receiving a clamping face of the male-die block on one side. Bayonet fasteners on hollow pistons in the mounting plate then engage the male dies, and a pressure medium then moves the hollow pistons to move the male dies against thrust pieces displacably in the hollow pistons and the thrust pieces against an adjusting wedge on the opposite side of the mounting plate.
