Description

Die Erfindung betrifft ein Schrägwalzwerk, das in bekannter Weise mit sogenannten Faßwalzen ausgestattet ist. Das Ziel der Erfindung sei, mit einfachen Mitteln eine gute Führung des Walzgutes vor und hinter der Schrägwalze zu erzielen.The invention relates to a cross rolling mill, which in a known manner is equipped with so-called barrel rollers. The aim of the invention is with simple Means to achieve good guidance of the rolling stock in front of and behind the skew roll.

Die Aufgabe ist an sich bekannt. Verschiedene Vorschläge wurden hierfür gemacht, so hat man Rohrführungen und Führungsrinnen oder andere feste Führungen vorgesehen, man hat auch mitunter die Walzen auf der einen oder auf der anderen Seite so ausgebildet, daß sie eine Führung des Werkstückes bewirken. Die festen Führungen haben sich nicht bewährt, weil sie einem zu starken Verschleiß ausgesetzt sind, eine einseitige Führung reicht aber nicht aus, um einen einwandfreien Durchgang des Walzgutes durch das Schrägwalzwerk zu gewährleisten.The task is known per se. Various suggestions have been made for this made, so you have pipe guides and guide troughs or other fixed guides provided, you also have the rollers on one or the other Side designed so that they cause a guide of the workpiece. The firm ones Guides have not proven themselves because they are exposed to excessive wear are, but a one-sided tour is not enough to ensure a smooth passage to ensure the rolling stock through the piercing mill.

Gemäß der Erfindung wird daher vorgeschlagen, daß wenigstens eine der Schrägwalzen über die Lager hinaus beiderseitig verlängert ist, diese Verlängerung als Führungskörper ausgebildet ist und entweder die Gestalt einer drehbaren Rolle oder eines fest mit der Schrägwalze verbundenen Bundes hat.According to the invention it is therefore proposed that at least one of the skew rollers is extended on both sides beyond the bearings, this extension is designed as a guide body and either the shape of a rotatable roller or a collar firmly connected to the skew roller.

Diese neuartige Ausbildung hat gegenüber den bekannten Rollenführungen den Vorteil, daß eine besondere Halterung für diese, die den Zugang zu den Schrägwalzen behindert, in Fortfall kommt.This novel training has compared to the known roller guides the advantage that a special holder for this, which gives access to the skew rollers handicapped, in failure comes.

Die Erfindung ist in einem Ausführungsbeispiel wiedergegeben. In der Zeichnung zeigt Abb. 1 eine der bekannten Walzengestalten, während Abb. 2 die erfindungsgemäße Ausbildung erkennen läßt. Der Hohlblock a, in dem die Dornstange b liegt, wird durch die tonneu- oder faßförmigen Schrägwalzen c bearbeitet. Durch die jenseits beider Lager vorgesehenen Bunde d wird, wie aus der Zeichnung zu entnehmen, eine gute Führung des sonst sich verwindenden Walzgutes herbeigeführt. Hierdurch ist man in der Lage, größere Einsatzgewichte zu verarbeiten bzw. längere Hohlblöcke zu erzielen, auch wird der Walzenverschleiß erheblich verkleinert und die Oberfläche des Walzgutes verbessert.The invention is shown in one embodiment. In the drawing, Fig. 1 shows one of the known roller designs, while Fig. 2 shows the design according to the invention. The hollow block a, in which the mandrel bar b lies, is processed by the barrel-shaped inclined rollers c. As can be seen from the drawing, the collars d provided on the other side of the two bearings ensure good guidance of the otherwise twisting rolled stock. This makes it possible to process larger weights or to achieve longer hollow blocks, the roll wear is also considerably reduced and the surface of the rolled stock is improved.
