Description

QuerwalzmaschineCross rolling machine

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 nachteilig hat sich bei den bekannten Querwalzmaschinen herausgestellt, daß sie nur begrenzte Stückzahlen pro Zeiteinheit erzeugen können; außerdem ist der Austausch der Werkzeuge aufwendig.It has been found to be disadvantageous in the known transverse rolling machines that they can only produce limited quantities per unit of time; also is the Exchanging tools is time-consuming.

Die bekannten Querwalzmaschinen haben allerdings den Nachteil, daß es Beschränkungen bezüglich der Taktzeit gibt und damit die Fertigung hoher Stückzahlen ausgeschlossen ist. Zwar könnte eine Verkürzung der Taktzeit durch Erhöhung der Walzendrehzahl in Betracht kommen, jedoch führt das sowohl zu erheblichen technischen Problemen als auch zu Unsicherheiten im Werkstcühandling.The known cross rolling machines have the disadvantage that there are restrictions regarding the cycle time and thus the production of large quantities is excluded. A shortening of the cycle time could increase of the roller speed, but this leads to considerable technical problems as well as uncertainties in the workshop handling.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Querwalzmaschine zu schaffen, mit der sich ohne die genannten Nachteile die Taktzeiten deutlich erhöhen lassen.The invention has for its object a generic cross rolling machine to create, with the cycle times without the disadvantages mentioned significantly increase.

Diese Aufgabe wird erfindungsgemäß in verblüffend einfacher Weise dadurch gelöst, daß die Walzenpaare von zwei in Modulbauweise ausgeführten Maschinenrahmen mechanisch miteinander gekoppelt und von einem gemeinsamen Antrieb angetrieben sind. Indem somit zwei baugleiche, parallel nebeneinander angeordnete Maschinen in Zwillingsbauweise betrieben werden, wozu aufgrund der mechanischen Kopplung lediglich eine Motor- und Getriebeeinheit benötigt wird, lassen sich bei einer Walzenumdrehung doppelte Stückzahlen erreichen. Hierzu bedarf es keiner unabhängigen Steuerung sowie Be- und Entladung der beiden Maschineneinheiten mit den umzuformenden bzw. fertiggestellten Werkstücken.According to the invention, this object is achieved in an amazingly simple manner by that the roller pairs of two modular machine frames mechanically coupled and by a common drive are driven. By thus two structurally identical, arranged side by side in parallel Machines are operated in twin construction, which is due to the mechanical Coupling only a motor and gear unit is required double the number of pieces per revolution. This requires there is no independent control and loading and unloading of the two machine units with the workpieces to be formed or finished.

Eine bevorzugte Ausführung der Erfindung sieht vor, daß die Walzen einen solchen Durchmesser aufweisen, der bei der Umformung eines Werkstückes nur den halben Umfang eines Walzenpaares erfordert, wobei die Werkzeuge halbschalenartig ausgebildet und an den Walzen der Walzenpaare eines jeden Maschinenrahmens um 180° versetzt angeordnet sind. Hierbei lassen sich mehrere Vorteile gleichzeitig erreichen. Denn bei einer kompletten Maschinenumdrehung wird jeweils nur ein Werkzeugpaar im Wechsel genutzt, gleichwohl liegt bei einer vollen Walzenumdrehung die doppelte Stückzahl vor. Die wechselweise Nutzung führt zu einer geringeren thermischen Belastung, denn während das Walzenpaar des einen Maschinenrahmens umformend wirkt, laufen die Walzen bzw. Werkzeuge der anderen Maschine frei in ihre Betriebsposition zurück. Wegen des wechselweisen Werkzeugeinsatzes kann die Antriebsleistung der Zwillingsmaschine wie für eine Einzelmaschine ausgelegt und gestaltet werden. Hinzu kommt noch, daß auch die zugehörigen Antriebskupplungen nur jeweils das Drehmoment für ein Walzenpaar, nämlich das mit den gerade umformenden Werkzeughälften übertragen müssen.A preferred embodiment of the invention provides that the rollers such Have diameter that only when forming a workpiece half the circumference of a pair of rollers required, the tools half-shell trained and on the rollers of the roller pairs of each machine frame are arranged offset by 180 °. There are several advantages to this reach at the same time. Because with a complete machine revolution each time only one pair of tools is used alternately, nevertheless there is a full one Roll revolution twice the number of pieces. The alternate use leads to a lower thermal load, because while the pair of rollers of one The rollers or tools of the machine frame are reshaping other machine freely in its operating position. Because of the alternate Tool use can drive the twin machine as for a Single machine can be designed and designed. In addition, the associated drive clutches only the torque for one pair of rollers, namely the need to transfer with the just forming tool halves.
