Description

Verfahren zur ununterbrochenen Herstellung von Lagerschalen aus Stahlblech mit Bleibronze Es ist ein Verfahren zur ununterbrochenen Herstellung von Lagerschalen aus Stahlblech mit Bleibronze bekannt, bei dem ein endloser Stahlstreifen benutzt wird, der an den Längsseiten U-förmig hochgebogen ist und der zur Erzielung einer guten Bindung zunächst auf die erforderliche Temperatur aufgeheizt, dann mit Bleibronze übergossen, abgeschreckt, zerschnitten und zu Lagerschalen gebogen wird. Es ist auch vorgeschlagen worden, das Band in gewissen Abständen mit Querrippen-, z. B. Aufwölbungen o. dgl., zu versehen, um einerseits ein Auseinanderfließen der Bronze auf dem Band zu vermeiden, andererseits bessere Erstarrungsverhältnisse für die Bronze zu schaffen.Process for the continuous production of bearing shells from sheet steel with lead bronze It is a process for the continuous manufacture of bearing shells Known from sheet steel with lead bronze, in which an endless steel strip is used is, which is bent up in a U-shape on the long sides and to achieve a good bond, first heated to the required temperature, then with lead bronze is poured over, quenched, cut up and bent into bearing shells. It is it has also been proposed to use the tape at certain intervals with transverse ribs, e.g. B. Bulges o. The like. To be provided, on the one hand, to prevent the bronze from flowing apart on the belt to avoid, on the other hand, better solidification conditions for the To create bronze.

Durch die vorliegende Erfindung ist die Anbringung derartiger Wülste überflüssig. In der beiliegenden Zeichnung ist das Verfahren schematisch dargestellt.The present invention enables the application of such beads superfluous. The process is shown schematically in the accompanying drawing.

Das Eisenband a, welches in üblicher Weise mit U-förmig hochgeschlagenen Längskanten versehen ist, durchläuft, in geeigneter Weise durch Rollen L geführt, den Ofen c, in dem es auf die zur Erzielung einer einwandfreien Bindung erforderliche Temperatur aufgeheizt wird. Nach Austritt aus dem Ofen c wird flüssige Bronze auf das Band aufgegossen, die in bekannter Weise durch die Abkühldusched zur Erstarrung gebracht wird. Das Wesender vorliegenden Erfindung besteht nun darin, daß das Band a abweichend von der Horizontalen mit Gefälle in Richtung auf die Abkühlstelle d angeordnet und bewegt wird. Da--bei ist Gefälle und Bewegungsgeschwindigkeit derart aufeinander abgestimmt, daß das vor der bereits erstarrten Bronze e gestaute, noch flüssige Metall f genügend lange auf das Band a einwirken kann, um eine einwandfreie Bindung zu erzielen. Dabei kann vorteilhaft der Eingußtiegel ä und die Ab'kühlstelle d zum Heizofen e so angeordnet werden, daß das flüssige Metall bis in den Ofen hineinsteht, so daß Oxydationen des Bandes beim Austritt aus dem gegebenenfalls mit neutralem -Gas gefüllten Ofen e vermieden werden. -The iron band a, which is folded up in the usual way with a U-shape Longitudinal edges are provided, runs through, guided in a suitable manner by rollers L, the oven c, in which it is on the necessary to achieve a perfect bond Temperature is heated. After exiting the furnace c, liquid bronze appears the tape is poured, which in a known manner by the Kühldusched to solidify is brought. The essence of the present invention is that the tape a deviating from the horizontal with a slope in the direction of the cooling point d is arranged and moved. The gradient and speed of movement are like that coordinated that the jammed before the already solidified bronze e, still liquid metal f can act on the band a long enough to produce a perfect To achieve bond. The pouring crucible and the cooling point can advantageously be used here d to the heating furnace e are arranged in such a way that the liquid metal extends into the furnace, so that oxidations of the tape when leaving the possibly with neutral -Gas-filled furnace e to be avoided. -

PATENTANSPRÜCHE: i Verfahren zum ununterbrochenen Überziehen eines an den Längsseiten U-förmig hochgeschlagenen endlosen Stahlbandes mit einer Iiupferbleilegierung zur Herstellung von Lagerschalen, dadurch gekennzeichnet, daß das Band abweichend von der Horizontalen mit Gefälle in Richtung auf die Ab'kühlstelle angeordnet und bewegt wird, wobei Gefälle und Bewegungsgeschwindigkeit derart aufeinander abgestimmt sind, daß das vor der bereits erstarrten Bronze gestaute flüssige Metall genügend lange auf das Stahlband einwirken kann, um eine feste Bindung herbeizuführen. z. Verfahren nach Anspruch i, dadurch gekennzeichnet, daß das auf dem Band stehende flüssige Metall bis in den Heizofen hineinragt. PATENT CLAIMS: i A method for the uninterrupted coating of an endless steel belt, which is turned up in a U-shape on the long sides, with a copper lead alloy for the production of bearing shells, characterized in that the belt is arranged and moved, deviating from the horizontal, with a slope in the direction of the cooling point, whereby The gradient and the speed of movement are coordinated with one another in such a way that the liquid metal accumulated in front of the already solidified bronze can act on the steel strip for a long enough time to bring about a firm bond. z. Method according to claim i, characterized in that the liquid metal standing on the belt extends into the heating furnace.
