Description

Die Erfindung betrifft eine Querwalzmaschine, umfassend zwei in einem Maschinenrahmen gelagerte, in gleicher Drehrichtung rotierende, gemeinsam angetriebene Walzen, die auf ihrem Umfang mit Werkzeuge bildenden Arbeitsflächen versehen sind.The invention relates to a cross rolling machine comprising two in a machine frame mounted, rotating in the same direction of rotation, jointly driven Rollers that provide work surfaces forming tools on their circumference are.

Eine solche Querwalzmaschine, auf der langgestreckte, Einschnürungen bzw. Bunde und Erhöhungen wie Nocken oder Rippen aufweisende metallische Werkstücke hergestellt werden, ist durch die DE 43 01 314 C2 bekanntgeworden. Das Walzgerüst bzw. der Maschinenrahmen weist dort zwei Träger mit je zwei Tragwänden und in diesen ausgebildeten Lagerstellen für Wellen auf. Auf den Wellen sind Walzen angeordnet, wobei jeder Träger eine Walze lagert und mindestens ein Träger durch Drehung um eine gemeinsame Achse zur Veränderung des Walzspaltes zwischen den Walzen relativ zum anderen Träger bewegbar ist. Aufgrund der Lagerung der Walzen an um eine gemeinsame Achse schwenkbar angeordneten Trägern soll auch bei einer Änderung des Walzspaltes die Achsrichtung der Werkstückzuführung symmetrisch zu den Achsen der Walzen verlaufen (vgl. DE 44 16 238 A1).Such a cross rolling machine on which elongated, constrictions or Metal workpieces with cuffs and elevations such as cams or ribs are made known by DE 43 01 314 C2. The The roll stand or the machine frame there has two beams, each with two supporting walls and in these trained bearings for shafts. On the waves rollers are arranged, each carrier supporting one roller and at least one a carrier by rotating around a common axis to change the Roll gap between the rollers is movable relative to the other carrier. by virtue of the storage of the rollers on a pivotable axis Beams should change the axial direction even if the roll gap changes the workpiece feed run symmetrically to the axes of the rollers (see DE 44 16 238 A1).

Als problematisch hat sich bei den bekannten Querwalzmaschinen der Austausch der Werkzeuge herausgestellt. Dies muß bei jedem Produktwechsel und natürlich bei Verschleiß erfolgen. Damit nicht die Walzenachse geöffnet werden muß, wozu es erforderlich ist, den Walzenkörper von festen Walzenlagerungen zu trennen, sind bei der eingangs genannten, bekannten Querwalzmaschine die Walzen auf einem über die Tragwände hinausragenden freien Ende der Wellen und somit fliegend angeordnet. Es braucht hier dann zwar nur ein Walzenlager von der Walze abgezogen zu werden, jedoch bringt der Verzicht auf ein zweites Lager bei der Werkstückumformung Nachteile mit sich.The exchange has been problematic in the known cross rolling machines of the tools exposed. This must be done with every product change and of course when worn. So that the roller axis does not have to be opened, for what it is necessary to separate the roller body from fixed roller bearings, are in the known cross rolling machine mentioned at the beginning of the rolls a free end of the waves protruding beyond the supporting walls and thus flying arranged. You only need one roller bearing from the roller to be deducted, however, the waiver of a second camp at Workpiece forming disadvantages.

Der Erfindung liegt die Aufgabe zugrunde, bei einer gattungsgemäßen Querwalzmaschine eine Bauweise der Walzen zu schaffen, die ohne umformtechnische Nachteile einen einfachen und schnellen Wechsel der Werkzeuge erlaubt.The invention has for its object in a generic cross rolling machine to create a construction of the rolls without forming Disadvantages allow easy and quick change of tools.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Werkzeug als Halbschale ausgebildet und auf einem Werkzeugträger angeordnet ist, der mit einer in Richtung der Walzenlängsachse durchgängigen und an seiner von dem Werkzeug abgewandten Seite offenen Trägerausnehmung auf die Werkzeugachse aufstülpbar und mit dieser zu einer festen Walzeneinheit verbindbar ist. Es läßt sich hiermit erreichen, daß zum Werkzeugwechsel weder ein Öffnen der Walzenachse noch ein Abziehen eines Lagers nötig ist. Denn nach dem Lösen von den Werkzeugträger mit einem Walzengrundkörper beispielsweise verbindenden Befestigungsschrauben kann der Werkzeugträger mit dem Werkzeug einfach nach oben, z.B. unter Zuhilfenahme eines Hallenkranes, von der Walzenachse abgehoben werden. Wenn zwei mit die erfindungsgemäßen Walzen aufweisenden Maschinenrahmen zu einer Zwillingsmaschine, d.h. nebeneinanderstehend angeordnet sind, können in der Wechselstellung der Walzen jeweils zwei Werkzeuge gleichzeitig, d.h. aus jedem Maschinenrahmen ein Werkzeug, mit einer Wechselaufnahme ausgehoben werden.This object is achieved in that the tool as Half-shell formed and arranged on a tool carrier, which with one continuous in the direction of the longitudinal axis of the roller and at its from that Side of the carrier recess facing away from the tool on the tool axis can be slipped on and connected to a fixed roller unit. It leaves hereby achieve that neither an opening of the roller axis for the tool change it is still necessary to remove a bearing. Because after loosening connecting the tool carrier with a roller base body, for example The tool holder can easily be tightened using the tool above, e.g. with the help of an indoor crane, lifted off the roller axis become. If two with the machine frame having rollers according to the invention to a twin machine, i.e. arranged side by side two tools can be used in the changing position of the rollers at the same time, i.e. one tool from each machine frame with an interchangeable holder be excavated.

Eine bevorzugte Ausführung der Erfindung sieht vor, daß die Trägerausnehmung einen eckigen Querschnitt besitzt und die Walzenachse mit einem komplementären Vierkantabschnitt ausgebildet ist. Nach dem Aufsetzen eines Werkzeugträgers mit seinem nach unten einseitig offenen Ende auf den Vierkantabschnitt und Verbinden des Werkzeugträgers mit dem Walzengrundkörper zu der festen Walzeneinheit, liegt aufgrund der eckigen Fügeverbindung eine hinsichtlich der Kräfteaufnahme und Übertragung beim Umformen optimierte Walzeneinheit vor.A preferred embodiment of the invention provides that the carrier recess has a square cross section and the roller axis with a complementary Square section is formed. After attaching a tool holder with its downward open end on the square section and connecting the tool carrier with the roller base body to the fixed roller unit, is due to the angular joint connection with regard to the force absorption and transfer during forming optimized roller unit.

Die Erfindung sieht in vorteilhafter Ausgestaltung vor, daß die Walzenachse unterhalb des Vierkantabschnitts eine Anbauplatte mit einer segmentartigen Werkstückzuführung aufweist. Im Zusammenspiel der beiden im Maschinenrahmen entweder übereinander liegend oder vorzugsweise nebeneinander angeordneten Walzen eines Walzenpaares übernimmt wechselweise immer die eine Walze die Zuführung des umzuformenden Werkstückes in den Walzenspalt, während jeweils die Walzen gemeinsam mit ihren sich ergänzenden Werkzeugen die Umformung vornehmen.The invention provides in an advantageous embodiment that the roller axis below of the square section a mounting plate with a segment-like workpiece feed having. In the interaction of the two in the machine frame either lying one above the other or preferably arranged next to one another Rolling a pair of rolls alternately always takes over the one roll Feeding the workpiece to be formed into the nip during each the rollers, together with their complementary tools, perform the forming make.
