Abstract

Bei einem Schnittsystem (1) für Drahtbearbeitungsmaschinen, mit einem Messerhalter (6), der ein beim Schnitt mit einem stationären Gegenschneidewerkzeug (12) zusammenwirkendes Messer (7) trägt und zur Ausführung einer hin- und hergehenden Bewegung über Verbindungsmittel (5) an einen Exzenterzapfen (4) oder eine Nockenscheibe an einer Kurbelwelle (3) angeschlossen ist, die ihrerseits von einem Elektromotor (2) angetrieben wird, wobei der Messerhalter (6) bei seiner hin- und hergehenden Bewegung in einer Führung (8) gleitet, die stationär angeordnet oder, bei starrer Verbindung von Verbindungsmitteln (5) und Messerhalter (6), um eine zur Drehachse der Kurbelwelle (3) parallele Achse (9) frei verschwenkbar ist, wird die Kurbelwelle (3) direkt von einem Asynchronmotor (2) angetrieben, an den eine Schwungmasse (10) angeschlossen ist, deren kinetische Energie beim Auftreffen des Messers (7) auf den Draht als Schnittkraft freigegeben wird, wobei der Asynchronmotor (2) je Schnittzyklus genau eine Umdrehung (360°) ausführt und so angesteuert wird, daß er nur bis zu Beginn des Schnitts beschleunigt und nach erfolgtem Schnitt abgebremst wird.

In a cutting system (1) for wire processing machines, with a knife holder (6) which carries a cooperating when cutting with a stationary counter cutting tool (12) knife (7) and to perform a reciprocating motion via connecting means (5) to an eccentric (4) or a cam disc is connected to a crankshaft (3), which in turn is driven by an electric motor (2), the blade holder (6) sliding in its reciprocating motion in a guide (8) arranged stationary or, in the case of a rigid connection of connecting means (5) and knife holder (6), about a parallel to the axis of rotation of the crankshaft (3) axis (9) is freely pivotable, the crankshaft (3) directly from an asynchronous motor (2) is driven to a flywheel (10) is connected, the kinetic energy is released when hitting the blade (7) on the wire as a cutting force, the asynchronous motor (2) per cutting cycle exactly one revolution (360 °) is executed and is controlled so that it accelerates only until the beginning of the cut and is braked after a successful cut.
