Abstract

Zum schnellen Spannen von Werkzeugteilen wird ein Federspannzylinder, der im wesentlichen aus einem Zylinder (1) und einem darin geführten, federbe­ aufschlagten Kolben (4) mit Kolbenstange (3) be­ steht, vorgeschlagen, wobei das freie Ende der Kol­ benstange (3) einen als negativer (female) Teil eines Bajonettverschlusses (12) ausgebildeten Kopf (3a) besitzt. Der dazugehörige entsprechende positive (male) Teil ist das Kopfstück (17) einer Schraube, die in eine Gewindebohrung des Maschinen­ teils (20) geschraubt ist, an das ein Werkstück (19) geklemmt werden soll. Das der Verschlußseite abgewandte Ende weist eine Muffe auf, die Teil einer hydraulischen Schnellkupplung (10) ist, mit der entgegen der Fe­ derkraft Druck auf den Kolben (4) ausgeübt werden kann. For quick clamping of tool parts, a Spring tensioning cylinder, which essentially consists of one Cylinder (1) and a guided in it open piston (4) with piston rod (3) is proposed, the free end of the col benstange (3) as a negative (female) part a bayonet catch (12) Head (3a) has. The corresponding one positive (male) part is the head piece (17) one Screw into a threaded hole in the machine partly (20) is screwed to the one Workpiece (19) is to be clamped. That the End facing away from the closure side has a sleeve on being part of a hydraulic Quick coupling (10), with which against the Fe derkraft pressure on the piston (4) are exerted can.

Insbesondere bietet sich die Verwendung dieser Schnellspannmutter bie Reifenheizpressen oder in Kunststofformblasmaschinen an, insbesondere zur Befestigung von Reifen- bzw. Blasformteilen. In particular, the use of these offers Quick release nut for tire presses or in Plastic blow molding machines, especially for Fastening of tire or blow molded parts.
