摘要:
Die vorliegende Erfindung betrifft eine hydraulische Dehnspanneinrichtung mit einem Grundkörper (2), einer Dehnbüchse (5) und einer Druckkammer (7), in die ein Hydraulikmittelkanal (8) mündet, an dessen von der Druckkammer (7) fernen Seite ein Zylinderraum (9) ausgebildet ist, welcher durch eine Spannschraube (10) verschlossen ist, die in ein in dem Zylinderraum (9) gehaltenes Einsatzelement (13) eingeschraubt ist und durch Drehen nach innen verstellbar ist. In dem Grundkörper (2) ist ein zentraler Kühlmittelzuführkanal (17) vorgesehen, der in die Aufnahme (6) mündet, um einem Werkzeug während des Betriebs ein Kühl- und/oder Schmiermittel zuzuführen. Der Zylinderraum (9) ist radial in dem Grundkörper (2) ausgebildet und der Zylinderraum (9) und das Einsatzelement (13) bilden einen Ringraum (17c) zwischen sich aus. In diesen Ringraum (17c) münden insbesondere an diametral gegenüberliegenden Positionen Bohrungsabschnitte (17a, 17b) des Kühlmittelzuführkanals (17), die durch den Ringraum (17c) miteinander verbunden sind.

The invention relates to a rapid clamping unit, more particularly for the locking of tool parts of moulding tools or of forming tools or of moulding tools or forming tools on associated moulding machines or forming machines, where the rapid clamping unit is lockable with a retainer part corresponding to the rapid clamping unit, where the rapid clamping unit encompasses a sheath element intended for axial engagement into the retainer part and a piston element axially engaging into the sheath element or engaging through the sheath element, and axially movable with respect to the sheath element between a locking position and an unlocking position, and also encompassing locking elements engaging at least to some extent through the sheath element in a radial direction, in such a way that the locking elements in the locking position are in contact with the piston element radially outwardly in order to engage from behind to lock the retainer part, and in the unlocking position can be shifted radially inwardly, in order to release the retainer part. The invention further relates to a rapid clamping system, a moulding tool or forming tool and a moulding machine or forming machine.

The invention relates to a gear mechanism (40), in particular a linkage mechanism, having a base unit (42) and a rotational unit (44) which is mounted such that it can be rotated relative to the base unit about an articulation axis (46; 18), wherein the base unit has a drive element (48; 10) which can be driven rotationally, in particular, perpendicularly with respect to the articulation axis, having two rotationally mounted rotary members (54, 56; 14, 16) which can be driven in opposite directions by the drive element and are arranged, in particular, coaxially with respect to one another, wherein each of the rotary members drives a coupling element (60, 62; 30, 32) which is operatively connected to it when the drive element is rotating, wherein the two coupling elements are arranged such that they are mounted rotatably in a cage (68) of the rotational unit and are operatively connected to one another in such a way that, and wherein the drive body is operatively connected to the rotary members, the rotary members are operatively connected to the respective coupling element and/or the two coupling elements are operatively connected to one another in such a way that the cage is rotated about the articulation axis together with the rotational unit when the coupling elements are driven.
