Abstract

Die Erfindung betrifft eine Vorrichtung zum mechanischen Fügen flächig aufeinanderilegender Bleche durch Umformen mit einem Werkzeugsatz aus mindestens einem Stempel und einer Matrize, die einen Hohlraum begrenzt, in den hinein gefügt wird, wobei mindestens eines dieser beiden Werkzeugteile über eine durch Fluidversorgung erzeugte Antriebskraft derart antreibbar ist, daß der Stempel unter Wirkung einer Umformarbeit Blechmaterial aus einer Blechebene herausverlagert und staucht, und das antreibbare Werkzeugteil einen mitbewegten, seine Eindringtiefe begrenzenden Anschlag aufweist. Für eine einfache Wegbegrenzung ist vorgesehen, daß der Anschlag von einem Schaltbolzen gebildet wird, der bei Erreichen einer wählbaren Eindringtiefe gegen ein Schaltgestänge verfahrbar ist, das in einem lösbaren Rasteingriff mit einem Schließelement eines in der Fluidversorgung angeordneten Ventils für eine Tiefenbegrenzung bringbar ist, wobei der Rasteingriff zur Aufrechterhaltung einer Durchflußstellung des Ventils vorgesehen ist, und der Schaltbolzen als am Schaltgestänge angreifender Mitnehmer ausgebildet ist für ein Ausrasten des Schaltgestänges am Schließelement und Schalten des Ventils in eine Sperrstellung zur Unterbrechung der Fluidversorgung.

Figure 00000001
The invention relates to a device for mechanically joining sheet metal lying flat on top of one another by forming with a tool set comprising at least one punch and a die, which delimits a cavity into which it is inserted, at least one of these two tool parts being drivable in this way via a drive force generated by fluid supply that the stamp moves sheet metal material out of a sheet metal plane and compresses it under the effect of forming work, and the drivable tool part has a moving stop that limits its depth of penetration. For a simple path limitation, it is provided that the stop is formed by a switching pin which, when a selectable penetration depth is reached, can be moved against a shift linkage which can be brought into a releasable locking engagement with a closing element of a valve arranged in the fluid supply for a depth limitation, the Locking engagement is provided to maintain a flow position of the valve, and the switching pin is designed as a driver engaging the shift linkage for disengaging the shift linkage on the closing element and switching the valve into a blocking position to interrupt the fluid supply.
