ABSTRACT:
A stamping or nibbling machine has upper and lower tool carriers, upper and lower tool magazines arranged respectively above and below the displacement range of a workpiece and rotatable about an axis of rotation which is substantially parallel to the longitudinal axis of movement of a male die in the upper tool carrier, tool carriers in each magazine, and a tool exchanger operable to move a tool from each magazine into a tool carrier and vice versa. All the tools in each magazine, except the tool to be exchanged, are arranged completely above and/or below the displacement range of the workpiece, and the tool to be exchanged is lifted by a lifting device, relative to its magazine, into a transfer plane for movement into the working position in the machine. All the tools in each magazine, except the tool to be exchanged, are covered by a cover plate , and the plates define the boundaries of the displacement plane of the workpiece and prevent engagement of the workpiece with tools in the magazines. At least the lower tool magazine has pivotaly mounted tool holders which extend radially from the axis of rotation of the magazine, and a wedge surface is provided for the tool holders, and forms a lifting device, this wedge surface being arranged at a position associated with the tool carrier of the machine tool.
