Description

Verfahren zum Bearbeiten eines Werkstückes Process for machining a workpiece
Die Erfindung betrifft ein Verfahren zum Bearbeiten eines zwischen einem Gegenhalter und einer Fuhrung von einer Klemmkraft gehaltenen Werkstuckes, indem in eine Flache des Werkstuckes ein Profil bspw. eine Prazisionsverzahnung, eingeformt wird.The invention relates to a method for machining a workpiece held between a counter-holder and a guide by a clamping force, in that a profile, for example a precision toothing, is molded into a surface of the workpiece.
Einformungen, beispielsweise Prägungen, in Werkstucken geschehen üblicherweise in Stanz- bzw. Feinschneidpressen . Hierbei wird das zu bearbeitende Werkstuck zwischen einem Gegenhalter und einer Fuhrung eingespannt und ein Stempel gegen das Werkstuck gefuhrt, wobei dieser Stempel die Prägung in dem Werkstuck hervorruft. Die Fuhrung des Stempels geschieht üblicherweise in vertikaler Ausrichtung zum Werkstuck hin, d.h., in einer Ausrichtung senkrecht zur Oberflache des Werkstuckes. Insbesondere, wenn schwierigere Profile in das Werkstuck eingeformt werden sollen, müssen mehrere Prageschritte durchgeführt werden. Beispielsweise beim Einformen einer Prazisionsverzahnung sind drei Schritte notwendig. In einem ersten Schritt wird das Werkstuck andererseits der eigentlichen Prageflache deformiert bzw. eingedruckt, so dass die Prageflache gegenüber der Deformationsstelle aus dem Werkstuck herausquillt. In einem zweiten Schritt werden durch einen Stempel, auf dessen Oberflache sich geometrisch spezifische Prageorgane befinden, Schlitze eingeprägt. In einem nächsten Prageschritt werden durch einen Prägestempel mit profilierter Stirnflache Verzahnungen in die Prageflache eingedruckt, wobei die Flanken der Schlitze entsprechend umgeformt werden. Insbesondere bei sagezahnartigen Verzahnungen lasst die Qualität dieser Prazisionsverzahnung 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 clamped between a counterholder and a guide and a stamp is guided against the workpiece, this stamp causing the embossing in the workpiece. The stamp is usually guided in a vertical orientation towards the workpiece, ie in an orientation perpendicular to the surface of the workpiece. Especially if more difficult profiles have to be molded into the workpiece several pre-steps are carried out. For example, three steps are necessary when molding a precision toothing. In a first step, on the other hand, the workpiece is deformed or pressed into the actual stamping surface, so that the stamping surface swells out of the workpiece opposite the deformation point. In a second step, slots are embossed by a stamp, on the surface of which there are geometrically specific embossing organs. In a next stamping step, teeth are pressed into the stamping surface by means of an embossing stamp with a profiled end face, the flanks of the slots being deformed accordingly. Particularly with sawtooth-like gears, the quality of these precision gears leaves much to be desired.
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 Werkstuck eingeformt werden können.The present invention has for its object to provide a method and an apparatus of the above. To develop a way with which even difficult profiles can be precisely molded into a workpiece.
Zur Losung dieser Aufgabe fuhrt, dass die Einformung m einem Winkel zur Klemmkraft erfolgt.The solution to this problem is that the molding takes place at an angle to the clamping force.
Dieses Verfahren hat den Vorteil, dass in einem einzigen Arbeitsschritt die Herstellung des gewünschten Profils in dem Werkstuck erfolgt.This method has the advantage that the desired profile is produced in the workpiece in a single step.
In einem ersten Ausfuhrungsbeispiel wird das Formelement selbst schräg gefuhrt, d.h., die Fuhrung erfolgt mit einer vertikalen und einer schräg versetzten Komponente. In der Praxis hat sich herausgestellt, dass hierdurch beispielsweise wesentlich exakterer Prazisionsverzahnungen hergestellt werden können, was insbesondere auf ein besseres Fliessverhalten des verpragten Materials in der Spitze der Verzahnung zurückzuführen ist.In a first exemplary embodiment, the shaped element itself is guided at an angle, that is to say the guidance takes place with a vertical and an obliquely offset component. In practice, it has been found that, for example, much more precise precision gears can be produced as a result, in particular on one better flow behavior of the protruded material in the tip 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 Werkstuckes nicht unbedingt plan zu sein. Unter Fläche wird auch verstanden, wenn nur in einen schmalen Grad des Werkstuckes ein Profil eingeprägt wird. Auch dieser Grad bildet dann im weiteren Sinne der Erfindung eine Flache.Which profile is produced should be of secondary importance. All possible profiles are conceivable, especially gearing. The teeth can be straight or rounded. Furthermore, the surface of the workpiece to be machined does not necessarily have to be flat. Surface is also understood when a profile is only embossed in a narrow degree of the workpiece. This degree then also forms a surface in the broader sense of the invention.
Eine erfmdungsgemasse Vorrichtung zur Durchfuhrung dieses Verfahrens weist zumindest eine Fuhrung und einen Gegenhalter auf, zwischen denen das zu bearbeitende Werkstuck eingespannt ist. Führung- bzw. Gegenhalter können plattenartig, wandartig oder sonstwie beliebig ausgebildet sein. Wesentlich ist, dass sich in der Fuhrung das Formelement befindet, welches in einem spitzen Winkel auf das Werkstuck zu gefuhrt wird. Einmal kann dies dadurch geschehen, dass das Formelement in einer entsprechenden Ausnehmung schräg gefuhrt wird.A device according to the invention for carrying out this method has at least one guide and a counter-holder, between which the workpiece to be machined is clamped. Guide or counterholders can be plate-like, wall-like or any other design. It is essential that the shaped element is located in the guide, which is guided towards the workpiece at an acute angle. On the one hand, this can be done by slanting the shaped element in a corresponding recess.
In einem bevorzugten Ausfuhrungsbeispiel ist jedoch dem Formelement ein zusatzlicher Keiltrieb zugeordnet, der eine Keilflache aufweist, die mit einer Schragfache an dem Formelement zusammenwirkt. Zusätzlich gleitet dieses Formelement mit einer weiteren Schragflache auf einer Steigflache innerhalb einer Ausnehmung in der Fuhrung, so dass das Formelement beim vertikalen nach oben Bewegen des Keiltπebes schräg ansteigt und mit seinem Muster in seiner Stirnflache das Profil in dem Werkstück erzeugt. Die Einleitung der Kraft muss im übrigen nicht zwangsläufig über das Werkzeug direkt, sondern kann auch mit einer Hydraulikkomponente aufgebracht werden.In a preferred exemplary embodiment, however, an additional wedge drive is assigned to the shaped element, which has a wedge surface which interacts with an inclined fold on the shaped element. In addition, this shaped element slides with a further inclined surface on a rising surface within a recess in the guide, so that the shaped element rises obliquely when the wedge is moved vertically upward and with its pattern in its end face generates the profile in the workpiece. The introduction of the force does not necessarily have to be directly via the tool, but can also be applied with a hydraulic component.
Die beste Kraftverteilung zwischen Keiltrieb und Formelement durfte dann gewahrleistet sein, wenn die erste Schragflache des Formelementes, die auf der Steigflache aufgleitet, mit der zweiten Schragflache, die mit der Keilflache an dem Keiltrieb zusammenwirkt, einen Winkel von 80° bis 100° e nach Lange und Tiefe der Prägung einschliesst .The best distribution of force between the wedge drive and the shaped element could be ensured if the first inclined surface of the shaped element, which slides on the rising surface, and the second inclined surface, which interacts with the wedge surface on the wedge drive, form an angle of 80 ° to 100 ° e according to Lange and depth of embossing.
In einem weiteren Ausfuhrungsbeispiel wird ein Formelement zwischen dem Gegenhalter und der Fuhrung in dem Spalt gefuhrt, in dem auch das Werkstuck selbst festgeklemmt ist. Das bedeutet, dass m diesem Fall durch das Formelement auf der Mantelflache des Werkstuckes ein Profil erzeugt wird, welches einem Muster auf dem Formelement entspricht.In a further exemplary embodiment, a shaped element is guided between the counter-holder and the guide in the gap in which the workpiece itself is also clamped. This means that in this case the shaped element creates a profile on the lateral surface of the workpiece which corresponds to a pattern on the shaped element.
Die Bewegung dieses Formelementes wird der Einfachheit halber wiederum über einem Keiltrieb bewirkt, der in Ausnehmungen n dem Gegenhalter bzw. der Fuhrung gefuhrt ist. Dabei wirkt eine Keilflache des Keiltriebes mit einer Schragflache an dem Formelement zusammen, so dass das Formelement gegen die Mantelflache des Werkstuckes getrieben wird.For the sake of simplicity, the movement of this shaped element is in turn effected by means of a wedge drive which is guided in recesses n in the counter-holder or the guide. A wedge surface of the wedge drive interacts with a bevel surface on the shaped element, so that the shaped element is driven against the outer surface of the workpiece.
Bei einem weiteren Ausfuhrungsbeispiel der Erfindung erfolgt das Einformen eines Profils in das Werkstuck durch eine Dreh-/Schubbewegung eines entsprechenden Formelementes, das auf seiner Stirnflache das Muster für das Profil aufweist. In diesem Fall befindet sich eine geeignete Ausnehmung in der Fuhrung, so dass sich das Formelement in dieser Führung vertikal nach oben bei gleichzeitiger Drehbewegung bewegen kann. In a further exemplary embodiment of the invention, a profile is molded into the workpiece by a rotary / pushing movement of a corresponding shaped element which has the pattern for the profile on its end face. In this case there is a suitable recess in the guide, so that the Form element in this guide can move vertically upwards while rotating.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausfuhrungsbeispiele sowie anhand der Zeichnung; diese zeigt in Figur 1 einen schematisch dargestellten Querschnitt durch einen Teil einer erfmdungsgemassen Vorrichtung zum Herstellen eines Werkstuckes;Further advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawing; 1 shows a schematically represented cross section through part of a device according to the invention for producing a workpiece;

Figur 3 einen schematisch dargestellten Querschnitt durch einen Teile eines weiteren Ausfuhrungsbeispiels einer erfmdungsgemassen Vorrichtung zum Herstellen eines Werkstuckes .FIG. 3 shows a schematically illustrated cross section through a part of a further exemplary embodiment of a device according to the invention for producing a workpiece.
Gemäss Figur 1 wird in einer Flache 2 gemäss eines Werkstuckes 1 ein Profil, bspw. eine Prazisionsverzahnung 3, eingeformt. Dieses Werkstuck 1 wird zwischen einem Gegenhalter 4 und einer Fuhrung 5 eingeklemmt.According to FIG. 1, a profile, for example a precision toothing 3, is formed in a surface 2 according to a workpiece 1. This workpiece 1 is clamped between a counter holder 4 and a guide 5.
In der Fuhrung 5 ist eine Ausnehmung 6 vorgesehen, die durch eine Steigflache 7 eine schräg ansteigende Auflage für ein Formelement 8 ausbilden. Dieses Formelement 8 besitzt in einer Stirnflache, die zu dem Werkstuck 1 hin ausgerichtet ist, ein Muster 9 eines Profils, welches dem Profil 3 entspricht, das durch dieses Muster 9 in das Werkstuck 1 eingeformt werden soll.In the guide 5, a recess 6 is provided, which form an inclined support for a shaped element 8 by means of a rising surface 7. This shaped element 8 has, in an end face which is oriented towards the workpiece 1, a pattern 9 of a profile which corresponds to the profile 3 which is to be molded into the workpiece 1 by this pattern 9.
Gegenüber von dem Muster 9 weist das Formelement 8 eine erste Schragflache 10 auf, welche auf der Steigflache 7 gleitet. In einem Winkel von etwa 90° zu dieser ersten Schragflache 10 verlauft eine zweite Schragflache 11, die wiederum mit einem Keiltrieb 12 zusammenwirkt Hierzu greift der Keiltrieb 12 mit eine Keilflache 13 die zweite Schragflache 11 an.Opposite the pattern 9, the shaped element 8 has a first inclined surface 10 which slides on the rising surface 7. A second inclined surface 11 runs at an angle of approximately 90 ° to this first inclined surface 10, which in turn interacts with a wedge drive 12 for this purpose the wedge drive 12 engages the second inclined surface 11 with a wedge surface 13.
Die Funktionsweise der vorliegenden Erfindung ist folgende:The operation of the present invention is as follows:
Das Werkstuck 1 wird zwischen Gegenhalter 4 und Führung 5 eingkle mt. Als Klemmkraft wirkt eine mit den Pfeilen 14.1 und 14.2 gekennzeichnete vertikale Kraft.The workpiece 1 is inserted between the counter holder 4 and the guide 5. A vertical force identified by the arrows 14.1 and 14.2 acts as the clamping force.
Auf den Keiltrieb 12 wird eine Schubkraft 15 aufgebracht, die den Keiltrieb 12 vertikal nach oben gegen das Werkstuck 1 hin drangt. Dabei druckt die Keilflache 13 das Fuhrungselement 8 nach rechts, wobei dieses auf der Steigfläche 7 aufgleitet, so dass sich das Muster 9 in das Werkstuck 1 einprägen kann und dort das Profil 3 erzeugt. Dies geschieht in einem spitzen Winkel w zu der Fläche 2 des Werkstückes 1 hin.A thrust 15 is applied to the wedge drive 12, which urges the wedge drive 12 vertically upwards against the workpiece 1. The wedge surface 13 presses the guide element 8 to the right, which slides on the rising surface 7, so that the pattern 9 can be impressed into the workpiece 1 and produces the profile 3 there. This is done at an acute angle w to the surface 2 of the workpiece 1.
Bei einem weiteren Ausfuhrungsbeispiel der er- findungsgemassen Vorrichtung wird das Werkstuck 1 ebenfalls zwischen einem Gegenhalter 4.1 und einer Fuhrung 5.1 gehalten. Auch hier wirkt die Klemmkraft 14.1 und 14.2. Allerdings soll dem Werkstuck 1 in diesem Ausfuhrungsbeispiel in seine Mantelflache 16 ein Profil eingeformt werden. Hierzu ist wiederum ein Formelement 8.1 vorgesehen, welches allerdings zwischen dem Gegenhalter 4.1 und der Fuhrung 5.1 gefuhrt ist. Eine Umformrichtung ist mit dem Pfeil 17 gekennzeichnet.In a further exemplary embodiment of the device according to the invention, the workpiece 1 is also held between a counter-holder 4.1 and a guide 5.1. The clamping force 14.1 and 14.2 also acts here. However, in this exemplary embodiment, the workpiece 1 is to be molded into its outer surface 16 in a profile. For this purpose, a shaped element 8.1 is again provided, which, however, is guided between the counter-holder 4.1 and the guide 5.1. A direction of deformation is indicated by arrow 17.
Das Formelement 8.1 weist eine Schragflache 18 auf, welche mit einer Keilflache 19 eines Keiltriebes 12.1 zusammenwirkt. Dieser Keiltrieb 12.1 ist in Ausnehmungen 20.1 und 20.2 in dem Gegenhalter 4.1 bzw. der Fuhrung 5.1 gefuhrt . Gemäss Figur 3 soll dem Werkstück 1 durch eine Dreh- /Schubbewegung ein Profil 3.1 eingeformt werden. Hierzu ist ein Formelement 8.2 in einer entsprechenden Ausnehmung 6.1 in der Führung 5.2 geführt, wobei ein entsprechender Dreh- /Schubantrieb lediglich schematisch mit 21 gekennzeichnet ist . The shaped element 8.1 has an inclined surface 18 which cooperates with a wedge surface 19 of a wedge drive 12.1. This wedge drive 12.1 is guided in recesses 20.1 and 20.2 in the counter-holder 4.1 or the guide 5.1. According to FIG. 3, a profile 3.1 is to be molded into the workpiece 1 by a rotary / pushing movement. For this purpose, a shaped element 8.2 is guided in a corresponding recess 6.1 in the guide 5.2, a corresponding rotary / thrust drive being identified only schematically by 21.
