Abstract: The present invention refers to a tool-changing mechanism that can be used especially in combination with a metal-forming press. Especially in the case of big and heavy forming tools, pairs of tools are difficult to exchange. The present invention intends to provide the possibility of exchanging also tools of this type rapidly and easily, the tool exchange being, in addition, carried out automatically, if desired. For this purpose, the tool-changing mechanism (1) includes a circulating means provided with a plurality of reception means (4a, 4b) for holding forming tools (5a, 5b). The tool-changing mechanism is adapted to be set up beside a metal-forming press. At a tool changing position, the tools can be pushed into the metal-forming press. Furthermore, the present invention refers to an arrangement comprising a metal-forming press and a tool-changing mechanism in the case of which said tool-changing mechanism is arranged directly at the side of the metal-forming press (10).

Abstract: The present invention refers to a quick clamping device for at least one tool of a machine tool, in particular for at least one bending or edging punch of a bending or edging press, comprising a clamping member and a safety and hold means for the tool, said clamping member being provided with an engagement strip which is pretensioned for engagement with a counterrecess on the tool shank and which is adapted to be actuated by a central operating member in a direction opposite to its pretension.
