Description

Die Erfindung betrifft ein Verfahren zum Bearbeiten eines zwischen einem Gegenhalter und einer Führung von einer Klemmkraft gehaltenen Werkstückes, indem in eine Fläche des Werkstückes ein Profil bspw. eine Präzisionsverzahnung, durch ein Formelement eingeformt wird, sowie eine Vorrichtung hierfür.The invention relates to a method for processing a between a counterhold and a guide of one Clamping force held by the workpiece in a surface of the Workpiece a profile e.g. a precision toothing, is molded by a shaped element, as well as a Device for this.

Einformungen, beispielsweise Prägungen, in Werkstücken geschehen üblicherweise in Stanz- bzw. Feinschneidpressen. Hierbei wird das zu bearbeitende Werkstück zwischen einem Gegenhalter und einer Führung eingespannt und ein Stempel gegen das Werkstück geführt, wobei dieser Stempel die Prägung in dem Werkstück hervorruft. Die Führung des Stempels geschieht üblicherweise in vertikaler Ausrichtung zum Werkstück hin, d.h., in einer Ausrichtung senkrecht zur Oberfläche des Werkstückes. Insbesondere, wenn schwierigere Profile in das Werkstück eingeformt werden sollen, müssen mehrere Prägeschritte durchgeführt werden. Beispielsweise beim Einformen einer Präzisionsverzahnung sind drei Schritte notwendig. In einem ersten Schritt wird das Werkstück andererseits der eigentlichen Prägefläche deformiert bzw. eingedrückt, so dass die Prägefläche gegenüber der Deformationsstelle aus dem Werkstück herausquillt. In einem zweiten Schritt werden durch einen Stempel, auf dessen Oberfläche sich geometrisch spezifische Prägeorgane befinden, Schlitze eingeprägt. In einem nächsten Prägeschritt werden durch einen Prägestempel mit profilierter Stirnfläche Verzahnungen in die Prägefläche eingedrückt, wobei die Flanken der Schlitze entsprechend umgeformt werden. Insbesondere bei sägezahnartigen Verzahnungen lässt die Qualität dieser Präzisionsverzahnung erheblich zu wünschen übrig.Deformations, for example embossing, in workpieces usually take place in punching or fineblanking presses. Here, the workpiece to be machined is between a Brackets and a guide clamped and a stamp guided against the workpiece, this stamp the Embossing in the workpiece. The leadership of the Stamp is usually done in a vertical orientation towards the workpiece, i.e. in an orientation perpendicular to the Surface of the workpiece. Especially when more difficult Profiles are to be molded into the workpiece several embossing steps are carried out. For example when forming a precision toothing there are three Steps necessary. In a first step it will Workpiece on the other hand of the actual stamping surface deformed or indented so that the embossing surface opposite the deformation point from the workpiece oozes out. In a second step, a Stamp on the surface of which is geometrically specific Embossing organs are located, slots are embossed. In one next stamping step are marked with a stamp profiled end face gears in the embossing surface indented, the flanks of the slots correspondingly be reshaped. Especially with sawtooth-like Gears leave the quality of this precision gearing much to be desired.

Aus der US 4 318 292 A ist bspw. ein Herstellungsverfahren für eine Zange bekannt. Beide Zangenschenkel greifen mit einer Verzahnung ineinander, wobei die Zähne schräge Seitenflanken aufweisen sollen. Zur Herstellung von derartigen Zähnen wird ein Formstempel in gerader Richtung auf einen Gegenhalter zugeführt, wobei ein Formraum gebildet wird, in dem der Zangenschenkel abgekröpft wird, so dass die Zahnflanke, die später schräg stehen soll, in vertikaler Richtung zur Klemmkraft angeordnet ist. In einem weiteren Arbeitsschritt wird die Abkröpfung des Zangenschenkels beseitigt, so dass als Ergebnis die Zahnflanke schräg steht.For example, a manufacturing method is known from US Pat. No. 4,318,292 known for a pair of pliers. Both pliers legs grip interlocking, the teeth being oblique Should have side flanks. For production of Such teeth become a straight stamp fed to a counterholder, a molding space is formed by cranking the leg of the pliers, so that the tooth flank, which will later be inclined, in is arranged in the vertical direction to the clamping force. In one Another step is the cranking of the Pliers legs removed, so that as a result the Tooth flank is at an angle.

Aus der GB 1 096 846 A, die die Basis für den Oberbegriff des Ansprüche 1 und 3 bildet, ist wiederum ein Verfahren und eine Vorrichtung zur Herstellung von profilierten Gegenständen im Pressverfahren bekannt. Dabei wird ein Werkstück zwischen einem Gegenhalter und einer Führung eingeklemmt und die Mantelfläche des Werkstückes durch ein Formelement senkrecht zur Klemmkraft angegriffen. In die Mantelfläche wird eine Verzahnung eingeformt.From GB 1 096 846 A, which forms the basis for the preamble of claims 1 and 3, is again a method and a Device for the production of profiled objects known in the pressing process. This is a workpiece clamped between a counterholder and a guide and the outer surface of the workpiece by a shaped element attacked perpendicular to the clamping force. In the outer surface a toothing is formed.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung der o.g. Art zu entwickeln, mit denen auch schwierigere Profile exakt in ein Werkstück eingeformt werden können.The present invention is based on the object Method and device of the above Kind of develop with which even more difficult profiles can be exactly in one workpiece can be molded.

Zur Lösung dieser Aufgabe führt, dass das Formelement in einem spitzen Winkel zur Klemmkraft oder mit einer Dreh-/Schubbewegung gegen die Fläche des Werkstückes geführt wird.To solve this problem, that the shaped element in at an acute angle to the clamping force or with a turning / pushing movement guided against the surface of the workpiece becomes.

Dieses Verfahren hat den Vorteil, dass in einem einzigen Arbeitsschritt die Herstellung des gewünschten Profils in dem Werkstück erfolgt.This procedure has the advantage of being in a single Step in the production of the desired profile in the workpiece.

In einem ersten Ausführungsbeispiel wird das Formelement selbst schräg geführt, d.h., die Führung erfolgt mit einer vertikalen und einer schräg versetzten Komponente. In der Praxis hat sich herausgestellt, dass hierdurch beispielsweise wesentlich exakterer Präzisionsverzahnungen hergestellt werden können, was insbesondere auf ein besseres Fliessverhalten des verprägten Materials in der Spitze der Verzahnung zurückzuführen ist.In a first embodiment, the shaped element itself guided at an angle, i.e. the guidance takes place with a vertical and an obliquely offset component. In the Practice has shown that this for example, much more precise precision gears can be produced, in particular on a better flow behavior of the embossed material in the Top of the toothing is due.

Welches Profil hergestellt wird, soll von untergeordneter Bedeutung sein. Denkbar sind alle möglichen Profile, insbesondere Verzahnungen. Die Verzahnungen können geradlinig oder aber auch gerundet sein. Ferner braucht die zu bearbeitende Fläche des Werkstückes nicht unbedingt plan zu sein. Unter Fläche wird auch verstanden, wenn nur in einen schmalen Grad des Werkstückes ein Profil eingeprägt wird. Auch dieser Grad bildet dann im weiteren Sinne der Erfindung eine Fläche. Which profile is produced should be of minor importance Be meaningful. All possible profiles are conceivable, especially gears. The gears can be straight or rounded. Furthermore, the The surface of the workpiece to be machined is not necessarily flat to be. Area is also understood if only in a profile is embossed in a narrow degree of the workpiece becomes. In the broader sense, this degree also forms the Invention an area.

Eine erfindungsgemässe Vorrichtung zur Durchführung dieses Verfahrens weist zumindest eine Führung und einen Gegenhalter auf, zwischen denen das zu bearbeitende Werkstück eingespannt ist. Führung- bzw. Gegenhalter können plattenartig, wandartig oder sonstwie beliebig ausgebildet sein. Wesentlich ist, dass sich in der Führung das Formelement befindet, welches in einem spitzen Winkel auf das Werkstück zu geführt wird. Einmal kann dies dadurch geschehen, dass das Formelement in einer entsprechenden Ausnehmung schräg geführt wird.An inventive device for performing this The method has at least one guide and one Counterholder on, between which the to be machined Workpiece is clamped. Guide or counterholders can plate-like, wall-like or any other design his. It is essential that the leadership Form element is located at an acute angle the workpiece is fed. This can be done once happen that the shaped element in a corresponding Recess is guided at an angle.

In einem bevorzugten Ausführungsbeispiel ist jedoch dem Formelement ein zusätzlicher Keiltrieb zugeordnet, der eine Keilfläche aufweist, die mit einer Schrägfäche an dem Formelement zusammenwirkt. Zusätzlich gleitet dieses Formelement mit einer weiteren Schrägfläche auf einer Steigfläche innerhalb einer Ausnehmung in der Führung, so dass das Formelement beim vertikalen nach oben Bewegen des Keiltriebes schräg ansteigt und mit seinem Muster in seiner Stirnfläche das Profil in dem Werkstück erzeugt.In a preferred embodiment, however Form element assigned an additional wedge drive, the one Has wedge surface with an inclined surface on the Form element interacts. In addition, this slides Shaped element with another inclined surface on one Rising area within a recess in the guide, see above that the shape element when moving the vertical upwards Wedge drive rises diagonally and with its pattern in its End face creates the profile in the workpiece.

Die Einleitung der Kraft muss im übrigen nicht zwangsläufig über das Werkzeug direkt, sondern kann auch mit einer Hydraulikkomponente aufgebracht werden.The introduction of the force does not necessarily have to be via the tool directly, but can also be used with a Hydraulic component are applied.

Die beste Kraftverteilung zwischen Keiltrieb und Formelement dürfte dann gewährleistet sein, wenn die erste Schrägfläche des Formelementes, die auf der Steigfläche aufgleitet, mit der zweiten Schrägfläche, die mit der Keilfläche an dem Keiltrieb zusammenwirkt, einen Winkel von 80° bis 100° je nach Länge und Tiefe der Prägung einschliesst. The best power distribution between the wedge drive and Form element should be guaranteed when the first Sloping surface of the molded element on the riser with the second inclined surface, which with the Wedge surface on the wedge drive cooperates, an angle of 80 ° to 100 ° depending on the length and depth of the embossing includes.

Bei einem weiteren Ausführungsbeispiel der Erfindung erfolgt das Einformen eines Profils in das Werkstück durch eine Dreh-/Schubbewegung eines entsprechenden Formelementes, das auf seiner Stirnfläche das Muster für das Profil aufweist. In diesem Fall befindet sich eine geeignete Ausnehmung in der Führung, so dass sich das Formelement in dieser Führung vertikal nach oben bei gleichzeitiger Drehbewegung bewegen kann. In a further embodiment of the invention a profile is molded into the workpiece a rotating / pushing movement of a corresponding one Form element that on its face the pattern for has the profile. In this case there is one suitable recess in the guide, so that the Form element in this guide vertically upwards can move simultaneously rotating movement.
