Abstract

Two locking clamp-bars are slidingly accommodated in two parallel T-slots of an upper plate and in T-slots of upper grippers of a press. Each locking clamp-bar has two T-pieces. Upon rising of a lower plate, acting as the press ram, together with the set of tools, the T-pieces of locking clamp-bars are in a first position, in which they can enter recesses in further T-slots in an upper part of the set of tools or in an upper auxiliary plate. By means of a drive device, the T-pieces are pushed into a second position, in which they snap into the further T-slots. In this press, a non-destructive removal of tools is ensured in the event of a defective chucking mechanism.
