Description
Die Erfindung bezieht sich auf eine Maschinenanlage zum Herstellen bzw. Fertigprofilieren des Felgenbereichs ein stückiger Kfz-Räder, insbesondere aus einem gegossenen, geschmiedeten oder anderweitig vorgefertigten Leichtme tallrohling im Zuge spanloser Bearbeitung, die aus einer aus Formwalze und im Oberflächenprofil korrespondierender Gegenrolle gebildeten Rollvorrichtung mit angetriebenen und gegeneinander zustellbaren Rollen sowie einer den Rohling aufnehmenden und in der Bearbeitungsposition hal tenden Werkstückaufnahme einer Be- und Entladestation besteht.The invention relates to a machine system for Manufacture or finish profiling of the rim area lumpy motor vehicle wheels, in particular from a cast, forged or otherwise prefabricated Leichtme tall blank in the course of non-cutting machining, which results from a from form roller and corresponding in the surface profile Counter roll formed rolling device with driven and mutually deliverable roles and one Blank receiving and in the processing position hal tendency workpiece holder of a loading and unloading station consists.
Eine Maschinenanlage der eingangs genannten Art ist aus der DE-OS 22 50 971 bekannt. Durch axiale Fixierung an den Rändern eines zunächst zylindrischen Felgenbett eiles soll eine Streckung in axialer Richtung während der Formgebung des Felgenbettes vermieden werden. Dies wird durch eine Vielzahl von am Umfang des Rohlings angeord neten Jochen ermöglicht, mit denen drehbare Gesenkwalzen gegen den allseits umschlossenen Rohling gedrückt werden. Dieses Verfahren ist fertigungstechnisch sehr aufwendig und in der Formgebung begrenzt. Zum Werkstück- bzw. Werkzeugwechsel müssen eine Vielzahl von Vorrichtungs teilen auseinandergefahren und auf sehr engem Raum nach gerüstet werden.A machine system of the type mentioned is out DE-OS 22 50 971 known. By axial fixation the edges of an initially cylindrical rim well Hurry is supposed to stretch in the axial direction during the shape of the rim base can be avoided. This is arranged by a variety of on the circumference of the blank neten Jochen, with which rotatable die rolls be pressed against the blank which is enclosed on all sides. This process is very complex in terms of production technology and limited in shape. For workpiece or Tool changes need a variety of fixtures divide and spread out in a very small space be prepared.
Aufgabe der vorliegenden Erfindung ist es, bei einer Maschinenanlage zum Herstellen bzw. Fertigprofilieren des Felgenbereichs einstückiger Kfz-Räder die beschrie benen Nachteile zu vermeiden und aus gegossenen, ge schmiedeten und/oder anderweitig vorgefertigten Leicht metallrohlingen das Felgenbett durch einen oder mehrere Rollvorgänge in seinen End- bzw. Fertigungszustand zu bringen.The object of the present invention is in a Machine system for manufacturing or finished profiling of the rim area of one-piece motor vehicle wheels to avoid the disadvantages and cast, ge forged and / or otherwise prefabricated light metal blanks the rim well by one or more Roll processes in its final or manufacturing state bring.
Gelöst wird diese Aufgabe durch eine Maschinenanlage gemäß aller Merkmale des Patentanspruches 1; damit gefertigte Räder sind infolge des geringen maschinellen bzw. vor richtungsmäßigen Anlagenaufwands relativ billig und besitzen zudem alle Vor züge der gegebenen und ebenso vom Gefüge u. dgl. her, auch die der geschmiedeten.This task is solved by a machine system according to all Features of claim 1; made with it Wheels are due to the low mechanical or front directional Plant costs are relatively cheap and also have all the advantages features of the given and also of the structure u. Like. forth, too that of the forged.
Die Zeichnung zeigt schematisch und als Seitenansicht eine erfindungsgemäße Fertigungseinrichtung.The drawing shows schematically and as a side view Manufacturing device according to the invention.
Bei einer aus Formwalze 1 und Gegenrolle 2, die beide ge mäß Pfeilen P 1, P 2 gegeneinander verstellbar sein können, gebildeten Rollvorrichtung, unterstützt die Formwalze 1 von innen her auf dem gesamten Übergangsbereich von Scheibenrad 3 zu Felgenschulter 3 a bis zum freien Felgenende 3 b hin den Rohling des späteren Rades, der mit seinem Scheibenteil frei drehbar am Werkzeugkopf 4 einr Werkstückaufnahme angeflanscht ist. Der Werkzeugkopf 4 wiederum sitzt an einem Schwenkarm 5, der gemäß Pfeil P 3 zum Wechsel eines fertiggeformten Rades gegen einen neuen Rohling, aus- und wieder eingefahren werden kann. Über ein Führungsteil 6 kann die gesamte Einheit, bestehend aus Werkzeugkopf 4 und Schwenkarm 5, zudem in nicht näher darge stellter Weise gemäß der Pfeile P 4 und P 5 noch zusätzlich horizontal und vertikal verstellbar sein.In a rolling device formed from the forming roll 1 and counter roll 2 , both of which can be adjusted according to arrows P 1 , P 2 against one another, the forming roll 1 supports from the inside over the entire transition area from the disk wheel 3 to the rim shoulder 3 a to the free rim end 3 b towards the blank of the later wheel, which is flanged with its disc part on the tool head 4 to a workpiece holder. The tool head 4 in turn is seated on a swivel arm 5 which , according to arrow P 3 , can be extended and retracted to change a finished wheel for a new blank. Via a guide part 6 , the entire unit, consisting of tool head 4 and swivel arm 5 , can also be additionally adjusted horizontally and vertically in a manner not shown in accordance with arrows P 4 and P 5 .
Beim Arbeitsvorgang drückt nun die Gegenrolle 2 den Bereich zwischen Felgenschulter 3 a und Felgenende 3 b in die gewünschte Endform "F"; hierbei dreht sich der Rohling, bedingt durch den Kontakt mit den Rollen und paßt sich durch die mit den Pfeilen angedeuteten Bewegungsmöglichkeiten der gesamten maschinellen Einheit dem Verformungsvorgang an. Zudem ist es vorgesehen, den Öffnungs hub der Gegenrolle im Eilgang, den Arbeitshub jedoch den Verformungsverhältnissen entsprechend angepaßt, auszuführen.When operation is now the counter-roller 2 presses the region between the bead seat and rim 3 a 3 b the end in the desired final "F"; the blank rotates due to the contact with the rollers and adapts to the deformation process by the movement of the entire machine unit indicated by the arrows. In addition, it is intended to execute the opening stroke of the counter roller in rapid traverse, but the working stroke is adapted to the deformation conditions.
