Abstract

Section wires for oven steel fabric are rolled with hard metal rollers by exerting axial pressure for pre-stressing the hard metal rollers to compensate for the forces which take effect on the rollers on shaping the rolling stock. This largely suppresses damaging tensile forces which can arise in the hard metal, being based on the recognition that hard metal is likely to fracture under strong tensile forces, but that it is highly resistant to compressive strains.

Description

"Verfahren zur Herstellung von Profildrähten, insbesondere für Baustahlgewebe, durch Walzen mit Hartmetallrollen" Beim Walzen von Strängen haben sich mit Hartmetall bestückte Walzen im Hinblick auf den Walzenverschleiß sowohl beim Kalt- als auch beim Warmwalzen gut bewährt. "Process for the production of profile wires, in particular for structural steel mesh, by rolling with hard metal rollers "When rolling strands have themselves with hard metal loaded rollers with regard to roller wear, both during cold and Well proven in hot rolling.

Beim Walzen von profilierten Strängen, z.B. von Profildrähten für Baustahlgewebe, liegen insofern Schwierigkeiten vor, als in den Profilwalzen starke Kerbwirkungen auftreten, die in dem verhältnismäßig spröden Hartmetall zu Rissen führen können. Die Erfindung macht sich den Umstand zunutze, daß Hartmetall, obwohl es bei stärkeren Zugspannungen rißanfällig ist, gegen Druckspannungen eine äußerst hohe Widerstandsfähigkeit hat.When rolling profiled strands, e.g. profiled wires for Structural steel mesh, there are difficulties in that there are strong ones in the profile rollers Notch effects occur that lead to cracks in the relatively brittle hard metal being able to lead. The invention makes use of the fact that hard metal, although it is susceptible to cracking at higher tensile stresses, extremely against compressive stresses has high resilience.

Die Erfindung betrifft ein Verfahren zur Herstellung von Profildrähten, insbesondere für Baustahlgewebe, durch Walzen mit Hartmetallrollen. Erfindungsgemäß werden die bei der Verformung des Walzgutes auf die Hartmetallrollen wirkenden Kräfte durch axiale Druckvorspannungen in den Hartmetallrollen kompensiert. Auf diese Weise wird das Aufkommen schädlicher Zugspannungen im Hartmetall weitgehend unterdrückt. The invention relates to a method for producing profile wires, especially for structural steel mesh, by rolling with hard metal rollers. According to the invention are the forces acting on the hard metal rollers during the deformation of the rolling stock due to axial compressive stresses in the Compensated carbide rollers. In this way, the occurrence of harmful tensile stresses in the cemented carbide is largely eliminated suppressed.

Eine Walzanordnung, mit der das erfindungsgemäße Verfahren ausgeübt werden kann, ist beispielsweise in der Zeichnung im Schnitt dargestellt An dem Achsstummel 1 ist der aus Hartmetall bestehende Walzring 2 unter Zwischenschaltung der konischen Spannbüchse 3 befestigt. A roller assembly with which the method according to the invention is practiced can be, is shown for example in the drawing in section on the stub axle 1 is made of hard metal rolling ring 2 with the interposition of the conical Clamping sleeve 3 attached.

Durch den Anlagering 4 und den Zwischenring 5 werden in dem Hartmetallring die notwendigen axialen Druckvorspannungen hervorgerufen. Die Höhe der Druckvorspannung kann durch die Betätigung der Vorspannmutter 6 eingestellt werden, die sich auf der mit dem Achsstummel verbundenen Endkappe 7 befindet. Die radiale Vorspannung kann mittels der Schraube 8 reguliert werden. eciftlich bei dieser Anordiung ist, daß die Druckvorspannungen auch in der unmittelbaren NachbarsehaSt der Walzkaliber wirksam werden. Das wird dadurch erreicht, daß der äußere Rand der Hartmetallwalzrollen nicht oder nur wenig über den äußeren Rand der die Durckspannungen hervorrufenden Spannringe herausragt. Denkt man sich an den Angriffsstellen der Druckringe 4 und 5 geradlinige Verbindungslinien in axialer Richtung gelegt, so müssen diese den Bereich der Kaliber schneiden.Through the abutment ring 4 and the intermediate ring 5 are in the hard metal ring caused the necessary axial compressive prestresses. The amount of pressure bias can be adjusted by operating the preload nut 6, which is located on the end cap 7 connected to the stub axle is located. The radial preload can be adjusted with the screw 8. is cautious with this arrangement, that the pressure prestresses also in the immediate vicinity of the rolling pass be effective. This is achieved in that the outer edge of the hard metal rollers not or only a little over the outer edge of the pressure stress causing Clamping rings protrudes. If you think of the points of attack of the pressure rings 4 and 5 straight connecting lines laid in the axial direction, these must be the Cut range of caliber.
