Abstract

Bei einer Presse (1) mit verstellbaren Werkzeugteilen, bspw. Lochstempeln ist vorzugsweise jedem Werkzeugteil (11) jeweils ein Sperrelement (42) zugeordnet, wobei das Sperrelement eine Sperr- und eine Freigabeposition aufweist. An dem Sperrelement ist eine Anlagefläche (45) vorgesehen, die in Flächenbereiche (45a bis 45d) unterteilt ist, zwischen den Flächenbereichen (45a bis 45d) sind Ausnehmungen ausgebildet. Die im Wesentlichen ebenen und bedarfsweise an ihren Kanten etwas angeschrägten Anlageflächen (45a bis 45d) bilden somit die Stirnflächen einer Verzahnung. Der erforderliche Hub des Sperrelements bei seiner Überführung aus Sperr- in Freigabeposition und umgekehrt kann somit auf die Zahnbreite beschränkt werden. Dies wiederum ermöglicht es, besonders schmale Sperrglieder oder Sperrriegel (42) zu schaffen, die, obwohl sie in Längsrichtung ihrer schmalen Anlagefläche zu verstellen sind, mit einem kurzen Verstellhub und somit mit einem leichten kleinen Verstellantrieb auskommen. Dies ermöglicht wiederum eine besonders schnelle Verstellung und große Pressenhubzahlen mit Verstellung bei jedem Hub.
