Description

Die Erfindung betrifft eine Ablängvorrichtung für einen Draht, der im Oberbegriff des Patentanspruchs 1 genannten Art.The invention relates to a cutting device for a wire, in the preamble of the Patent claim 1 mentioned type.

Ablängvorrichtungen der oben genannten Art dienen dem Ablängen von Draht beispielsweise Stahldraht. Insbesondere gilt es Produkte aus Draht mit einem runden Querschnitt möglichst verformungs- und gratfrei und unter einem gewissen Winkel auf ein Mass abzulängen. Mögliche Produkte sind beispielsweise Drahtringe, Drahtfedern oder dergleichen.Cutting devices of the above type serve for cutting wire, for example Steel wire. In particular, products of wire with a round cross-section as possible free from deformation and burrs and cut to a size at a certain angle. Possible products are, for example, wire rings, wire springs or the like.

Aus dem allgemein bekannten Stand der Technik sind Ablängvorrichtungen mit einem Gegenhalter zur Führung eines, in eine Vorschubrichtung bewegten Drahts und einem gegen den Gegenhalter bewegbaren Stechmeissel bekannt. Der eine Schneidkante aufweisende Stechmeissel ist durch eine Lagerführung in einem Winkel, insbesondere senkrecht, zu einer durch den Gegenhalter gebildeten Anlagefläche geführt. Beim Ablängvorgang wird der Vorschub gestoppt und der Stechmeissel bewegt sich mit der Schneidkante gegen den auf der Anlagefläche aufliegenden Draht und durchtrennt diesen durch einen sogenannten linearen Schnitt.From the well-known prior art are cutting devices with a counter-holder for guiding a, moving in a feed direction wire and a against the backstroke movable lancing chisel known. The one having a cutting edge Stechmeissel is by a bearing guide at an angle, in particular perpendicular to one guided by the anvil contact surface. During the cutting process, the feed rate is increased stopped and the lancing chisel moves with the cutting edge against the on the Contact surface resting wire and divides this by a so-called linear Cut.

Nachteilig an dieser bekannten Lösung ist, dass durch den linearen Schnitt Material im Bereich der Schnittfläche verdrängt wird und dieses zur Bildung eines, sich zumindest teilweise über den Drahtquerschnitt erstreckenden, Grates und zu einer Verformung des Drahtquerschnittes infolge einer Stauchung führt. Sowohl Grat als auch Verformung schränken an zumindest einem Drahtende die Anwendungsmöglichkeiten des derart abgelängten Drahts ein. A disadvantage of this known solution is that due to the linear cut material in the area the cut surface is displaced and this to form one, at least partially over the wire cross-section extending burrs and to a deformation of the wire cross-section as a result of compression. Both burr and deformation limit at least a wire end, the applications of the so-cut wire.

In einer weiteren, allgemein bekannten, Ablängvorrichtung ist ein Stechmeissel durch eine Lagerführung auf einer elliptischen Bahn mit einer auf die Vorschubgeschwindigkeit abgestimmten Geschwindigkeit geführt.In a further, generally known, cutting device is a lancing chisel by a Warehouse management on an elliptical orbit with a feed rate adapted to the feed rate Speed led.

Vorteilhaft an dieser Lösung ist, dass die Vorschubbewegung des Drahts für den Ablängen nicht gestoppt werden muss.An advantage of this solution is that the advancing movement of the wire for cutting to length does not have to be stopped.

Nachteilig an dieser weiteren bekannten Lösung ist, dass eine Steuerung der Lagerführung des Stechmeissels sich negativ auf die Wirtschaftlichkeit der Ablängvorrichtung bei der Herstellung auswirkt.A disadvantage of this further known solution is that a control of the bearing guide the cutting chisel adversely affects the economics of the cutting device during manufacture effect.

Die gattungsgemässe JP 08 108238 A zeigt eine über Nocken zwangsgesteuerte Ablängvorrichtung für einen Draht mit einer Gegenschneide und mit einem, in einer Lagerführung, gegen die Gegenschneide bewegbaren, eine Schneidkante aufweisenden Stechmeissel. Die Lagerführung erlaubt ein Bewegen der Schneidkante in Vorschubrichtung des Drahtes und ein Verschwenken des Stechmeissels um eine Drehachse, die in dem der Schneidkante abgewandten Bereich des Stechmeissels angeordnet ist.The generic JP 08 108238 A shows a positively controlled over cam cutting device for a Wire with a counter-blade and with one, in a bearing guide, against the counter-blade movable, a cutting edge having Stechmeissel. The camp management allows moving the cutting edge in the feed direction of the wire and pivoting of the lancing tool about an axis of rotation which faces away from the cutting edge Area of the lancing chisel is arranged.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Ablängvorrichtung für Draht zu schaffen, die ein grat-, verformungsfreies und wirtschaftliches Ablängen von Draht gewährleistet.The present invention has for its object to provide a cutting device for wire create a burr-free, deformation-free and economical cutting of wire.

Erfindungsgemäss wird die Aufgabe dadurch gelöst, dass die Drehachse in einem sich entgegen der Vorschubrichtung erstreckenden Abstand von der Schneidkante angeordnet ist.According to the invention, the object is achieved in that the axis of rotation in a counter the feed direction extending distance from the cutting edge is arranged.

Dadurch, dass die Bewegung der Schneidkante in Vorschubrichtung möglich ist, wird beim Durchtrennen eines Drahts eine Stauchung des Querschnitts des Drahts verhindert, da die Schneidkante in Vorschubrichtung des Drahtes ausweichen kann. Ferner ist keine kostenaufwändige Steuerung für die Lagerführung und den Stechmeissel notwendig, wie dies beispielsweise bei einem motorisch Antrieb des Stechmeissels in Vorschubrichtung notwendig ist. In einer bevorzugten Ausführungsform ist die Schneidkante fest am Stechmeissel angeordnet.The fact that the movement of the cutting edge in the feed direction is possible, is in Cutting a wire prevents a compression of the cross section of the wire, as the Cutting edge can escape in the feed direction of the wire. Further, no expensive Control for the bearing guide and the Stechmeissel necessary, as for example in a motor drive of Stechmeissels in the feed direction necessary is. In a preferred embodiment, the cutting edge is fixedly arranged on the lancing chisel.

Die Lagerführung erlaubt ein Verschwenken des Stechmeissel um eine Drehachse in Vorschubrichtung.The bearing guide allows pivoting of the lancing chisel about a rotation axis in the feed direction.

Die Drehachse ist an dem der Schneidkante gegenüberliegenden Endbereich angeordnet, beispielsweise verläuft die Drehachse etwa durch die quer zur Vorschubrichtung und der Vorschubrichtung abgewandten Kante des Stechmeissels. Damit wird ein Verschwenken der Schneidkante etwa in Vorschubrichtung erleichert. The axis of rotation is at the opposite end of the cutting edge arranged, for example, the axis of rotation extends approximately through the transverse to the feed direction and the feed direction facing away edge of the lancing chisel. This is a pivoting the cutting edge facilitates approximately in the feed direction.

Die Drehachse ist in dem der Schneidkante in Vorschubrichtung abgewandten Bereich des Stechmeissels angeordnet. Dadurch wird durch die Schnittkraft ein Drehmoment am Stechmeissel erzeugt, das den Stechmeissel mit Drehsinn in Vorschubrichtung um die Drehachse verschwenkt. Die in den Draht eingedrungene Schneidkante des Stechmeissels bringt durch die Schwenkbewegung in den stehenden Draht eine Zugkraft in Vorschubrichtung ein. Der noch nicht durchtrennte Querschnitt des Drahtes wird durch die Zugkraft im Schnittbereich verjüngt und abgerissen. Somit wird der Schnittdruck auf den Draht minimiert und dadurch auch die Verformung des Drahtquerschnittes und eine Gratbildung vermieden.The axis of rotation is remote from the cutting edge in the feed direction Area of the lancing chisel arranged. As a result, the cutting force is a torque produced at the lance, which the lance with rotation in the feed direction to the Rotated pivot axis. The cutting edge of the lancing bit that has penetrated the wire brings by the pivoting movement in the stationary wire a tensile force in the feed direction one. The not yet severed cross section of the wire is due to the tensile force in Cutting area tapered and torn off. Thus, the cutting pressure on the wire is minimized and thereby also the deformation of the wire cross-section and a burr formation avoided.

Vorteilhafterweise weist die Lagerführung ein Rückstellelement und eine in die Vorschubrichtung wirkende Anschlagschulter auf, wobei der Stechmeissel zumindest im Bereich der Schneidkante in Vorschubrichtung durch das Rückstellelement vorgespannt ist und in der Ausgangsposition in Kontakt mit der Anschlagschulter steht. Damit ist eine sichere Führung des Stechmeissels in Vorschubrichtung sichergestellt. Insbesondere ist durch die Anschlagschulter die Ausgangsposition des Stechmeissels definiert. Ferner stellt das Rückstellelement einerseits eine Führung des Stechmeissels während des Trennvorgangs sicher und andererseits in der Ausgangsposition ein Anpressen des Stechmeissels an die Anschlagschulter. In einer weiteren Ausführungsform ist die Federkraft des Rückstellelements justierbar ausgebildet.Advantageously, the bearing guide has a return element and one in the feed direction acting stop shoulder, wherein the lancing chisel at least in the Cutting edge is biased in the feed direction by the return element and in the Starting position is in contact with the stop shoulder. This is a safe guide of the lancing chisel in the feed direction. In particular, by the stop shoulder defines the starting position of the lancing chisel. Furthermore, the reset element on the one hand a guide of the lancing chisel during the separation process safe and on the other hand, in the starting position a pressing of the lancing bit to the stop shoulder. In a further embodiment, the spring force of the return element is adjustable educated.

Der Stechmeissel steht vorzugsweise in Ausgangsposition senkrecht zur Anlagefläche, um einen möglichst gratfreien Schnitt sicherzustellen. Je nach dem gewünschten Schnitt kann der Stechmeissel jedoch auch um einen Winkel geneigt in der Ausgangsposition stehen.The lancing chisel is preferably in the starting position perpendicular to the contact surface to to ensure a burr-free cut. Depending on the desired cut can However, the lancing tool also inclined by an angle in the starting position.

Die Anlagefläche weist vorteilhafterweise eine Führungsvorrichtung zur Führung des Drahts auf, um ein seitliches Ausweichen des Drahts während des Ablängvorgangs zu verhindern.The contact surface advantageously has a guide device for guiding the wire on to prevent lateral deflection of the wire during the cutting process.

Vorzugsweise weist die Führungsvorrichtung einen zur Anlagefläche offen ausgebildeten, in Vorschubrichtung verlaufenden, vorzugsweise etwa mit dem Radius des Drahtes gerundeten, Führungskanal auf, um durch diese Gegenkontur beim Schneiden die Verformung gering zu halten und eine konstruktiv einfache und dadurch wirtschaftliche Lösung sicherzustellen.Preferably, the guide device has an opening formed open to the contact surface, in Advancing direction, preferably rounded approximately with the radius of the wire, Guide channel to low by this counter contour when cutting the deformation to keep and to ensure a structurally simple and therefore economical solution.

In Fig. 1 befindet sich der gestrichelt dargestellte Stechmeissel 1 in der Ausgangsposition, in der er in Kontakt mit der Anschlagschulter 8 steht. Das entgegen der Vorschubrichtung V des Drahts 4 wirkende Rückstellelement 7 drückt den Stechmeissel 1 an die Anschlagschulter 8. Ferner weist die Lagerführung 6 einen senkrecht zur Anlagefläche 3 bewegbaren Befestigungsbolzen 9 auf, der eine am Stechmeissel 1 angeordnete Durchgangsbohrung 11 durchgreift. Die Durchgangsbohrung 11 ist vorzugsweise an dem von der Anlagefläche 3 abgewandten Endbereich des Stechmeissels 1 mit einem, sich entgegen der Vorschubrichtung V erstreckenden Abstand a von der Schneidkante 5 angeordnet. Wirkt eine Kraft in eine Stechrichtung S, so bewirkt der, sich senkrecht zur Stechrichtung S erstreckende, Abstand a ein Verschwenken des Stechmeissels 1, insbesondere der Schneidkante 5, gegenüber dem Draht 4.The bearing guide 6 has a return element 7 and a stop shoulder 8. In Fig. 1 is the dashed chisel 1 in the starting position in which he is in Contact with the stop shoulder 8 stands. The opposite to the feed direction V of the wire 4 acting return element 7 presses the chisel 1 to the stop shoulder 8. Further the bearing guide 6 has a fastening bolt 3 which can be moved perpendicularly to the contact surface 3 9, which passes through a arranged on the chisel 1 through hole 11. The Through hole 11 is preferably on the end face remote from the contact surface 3 of the chisel 1 with a, opposite to the feed direction V extending Distance a from the cutting edge 5 is arranged. Acts a force in a lancing direction S, so causes, perpendicular to the piercing direction S extending distance a pivoting of the lancing chisel 1, in particular the cutting edge 5, with respect to the wire 4.

Der Gegenhalter 2 weist zur seitlichen Führung des Drahts 4 in Vorschubrichtung V, eine Führungsvorrichtung auf. Die Führungsvorrichtung weist einen zur Anlagefläche 3 offen ausgebildeten, in Vorschubrichtung V verlaufenden, halbkreisförmigen Führungskanal 12 auf, wie dies insbesondere aus Fig. 2 hervorgeht.The anvil 2 has for the lateral guidance of the wire 4 in the feed direction V, a Guide device on. The guide device has a contact surface 3 to open, in the feed direction V extending, semicircular guide channel 12, as can be seen in particular from FIG.

Beim Ablängverfahren wird der Draht 4 in Vorschubrichtung V durch den Führungskanal 12 gelenkt auf dem Gegenhalter 2 bewegt. Der Stechmeissel 1 befindet sich in der in Fig. 1 gestrichelt dargestellten Ausgangsposition in der er an der Anschlagschulter 8 ansteht. Zunächst wird der Stechmeissel 1 durch die Lagerführung 6 an der gewünschten Position des Drahts 4 in die Stechrichtung S im wesentlichen quer zur Anlagefläche 3 bewegt. Die Anschlagschufter 8, das Rückstellelement 7 und der Befestigungsbolzen 9, insgesamt als Lagerführung 6 bezeichnet, bewegen sich mit. Tritt der Stechmeissel 1 mittels der Schneidkante 5 in Kontakt mit der Aussenkontur 13 des Drahts 4, beginnt der Trennvorgang. Beim Trennvorgang bewegt sich der Stechmeissel 1 zunächst weiter in Stechrichtung S und die Bewegung in Vorschubrichtung V des Drahts 4 wird gestoppt. Beim Durchtrennen des Drahts 4 wird der Stechmeissel 1 entgegen der Federkraft des Rückstellelements 7 in Vorschubrichtung V um die durch den Befestigungsbolzen 9 gebildete und in einem, entgegen der Vorschubrichtung V verlaufenden, Abstand a von der Schneidkante 5 um die Drehachse verschwenkt. Ist der Draht 4 durchgetrennt, wird der Stechmeissel 1 wieder in die Ausgangsposition zurückbewegt. Vorzugsweise ist die Federkraft des Rückstellelements 7 justierbar gestaltet.When Ablängverfahren the wire 4 in the feed direction V through the guide channel 12th guided on the anvil 2 moves. The Stechmeissel 1 is in the dashed lines in Fig. 1 shown starting position in which he is present at the stop shoulder 8.
