Description
Das Profilieren von Bandeisen oder Metallen erfolgte bisher mittels Stahlwalzen oder Ziehwerkzeugen aus Stahl, da der Stahl, insbesondere Spezialstahl, eine große Wider-' Standsfähigkeit gegen Verschleiß/ aufweist. Wider Erwarten hat sich nun aber gezeigt, daß es wesentlich vorteilhafter ist, die Werkzeuge für die Profüierung aus Bronze herzustellen. Es wurde nämlich festgestellt, daßThe profiling of steel strips or metals was previously done by means of steel rollers or Drawing tools made of steel, as the steel, in particular Special steel, a great resistance to wear / has. Contrary to expectations, however, it has now been shown that it is much more advantageous to use the tools to be made of bronze for the profile. It was found that
ίο sich bei der Benutzung von Bronzewalzen oder Bronzeziehwerkzeugen 'eine viel glattetee und reibfreiere Oberfläche ergibt als bei der bisher allein üblichen Verwendung von Stahlwerkzeugen. Die mit Bronzewerkzeugeri hergestellten Erzeugnisse haben ein viel schöneres Aussehen.ίο when using bronze rollers or bronze drawing tools' a much smoother tea and a friction-free surface results than with the previously common use of steel tools. The products made with bronze tools have a much nicer look Appearance.
Dieser Vorteil wird nun nicht etwa erkauft durch den-Nachteil eines höheren Kostenaufwandes. Es ist im Gegenteil die Verwendung von Bronzewerkzeugen vorteilhafter. Die Bronzewalzen können schon beim Gießen eine der 'endgültigen Form angenäherte Form erhalten, so daß auch bei stark profilierten Stücken nur ein verhältnismäßig geringes Nacharbeiten durch Drehen erforderlich ist.This advantage is not bought at the cost of the disadvantage of higher costs. On the contrary, the use of bronze tools is more beneficial. the Bronze rollers can get a shape that approximates the final shape during casting, so that even with heavily profiled pieces only a relatively small one Reworking by turning is required.
Sowohl der bei der Bearbeitung sich ergebende' Abfall als auch der ganze Walzenkörper nach der Abnutzung des Profils haben noch fast ■den Wert des neuen Materials, während die Stahlwalzen nach Abnutzung fast wertlos sind.Both the waste resulting from the machining and the entire roller body after the wear and tear of the profile still have almost ■ the value of the new material, while the Steel rollers are almost worthless after wear and tear.
Dieser Vorteil tritt ganz besonders dann in Erscheinung, wenn nur geringe Mengen von einem bestimmten Profil herzustellen sind, also oftmals ein Wechsel des Profils eintritt. Die Kosten der Walzenherstellung sind dann bei Bronzewalzen verhältnismäßig gering, während sie bei der Benutzung von Stahlwalzen sehr hoch sind, da die Stahlwalzen fast wertlos werden. This advantage occurs especially in Appearance when only small quantities of a certain profile are to be produced, so there is often a change in profile. The cost of roll manufacturing is then in the case of bronze rollers it is relatively low, while it is relatively low when steel rollers are used are very high as the steel rollers become almost worthless.
Die bisher nicht bekannte Benutzung von Walzen und Ziehwierkzeugen aus Bronze bietet somit erhebliche Vorteile- sowohl in bezug auf. die Herstellungskosten als auch auf die Güte des Erzeugnisses.The previously unknown use of rollers and drawing tools made of bronze offers thus considerable advantages - both in terms of. the manufacturing costs as well as the Quality of the product.
