Abstract

The wire from which the reinforcing rods are made is unwound from the spool, straightened out and drawn or reduced in diameter by any conventional method such as rolling, to give it a profile. Before the material is passed through the drawing die or the roll, it is sprayed with a water-oil emulsion. The spraying process is carried out before each drawing or rolling stage. The emulsion consists of 5 to 25% oil and 95 to 75% water. The oil used has a low viscosity. The use of the oil emulsion improves the throughput and reduces wear on the work rolls or dies etc.

Das vorstehend geschilderte an sich bekannte Verfahren variiert in der Praxis häufig, so daß die vorstehenden Angaben (dies gilt auch für den Patentanspruch im Oberbegriff) lediglich als richtunggebend anzusehen sind.The above-described method known per se often varies in practice, so that the above Information (this also applies to the patent claim in the preamble) is only to be regarded as indicative.

Zum Stand der Technik sei erwähnt, daß das Naßziehen von Drähten seit Jahrzehnten bekannt ist.Regarding the state of the art, it should be mentioned that the wet drawing of wires has been known for decades.

Aufgabe der Erfindung ist es, das Fertigungsverfahren von Bewehrungsstäben (-drähten) zu beschleunigen (einen größeren Durchsatz pro Zeiteinheit zu erreichen) und den Verschleiß der Werkzeuge zu mindern.The object of the invention is the manufacturing process of reinforcing bars (wires) to accelerate (a to achieve greater throughput per unit of time) and to reduce tool wear.

Gelöst wird die gestellte Aufgabe dadurch, daß auf den durchlaufenden Draht vor dem Aufbringen einer Verformungskraft mittels Walzrollen mindestens einmal eine Emulsion, bestehend aus Wasser und Öl, aufgesprüht wird.The problem posed is achieved in that a deformation force is applied to the wire passing through it before it is applied an emulsion consisting of water and oil is sprayed on at least once by means of roller rollers.

Definitionsgemäß ist "vor dem Aufbringen ...." im weitesten Sinne auszulegen.According to the definition, "before application ..." is to be interpreted in the broadest sense.

Vorzugsweise soll eine schweißfreundliche Emulsion (insbesondere öl) Verwendung finden, insbesondere dann, wenn Schweißvorgänge folgen, beispielsweise Bewehrungsmatten hergestellt werden.A sweat-friendly emulsion (especially oil) are used, especially when welding operations follow, for example reinforcement meshes getting produced.

Das Verfahren ist weiter gekennzeichnet durch ein mehrmaliges Besprühen·mit Emulsion, und zwar soll das jeweils weitere Besprühen immer dann erfolgen, wenn nach dem vorherigen Besprühen mindestens, ein Arbeitsvorgang mittels Walzrollen durchgeführt wird. Die nachfolgende Besprühung kann mit einer fetteren Emulsion durchgeführt werden. " . - The method is further characterized by multiple spraying with emulsion, and the further spraying should always take place when after prior to spraying at least one operation is carried out by means of rollers. The following Spraying can be done with a fatter emulsion. ". -

Eine Emulsion ist dadurch gekennzeichnet, daß sie aus 5% Öl und 95% Wasser hergestellt wird; eine andere mögliche Emulsion besteht beispielsweise aus 10% bis25% Öl und 90% bis 75% Wasser. Zwischenwerte sind ebenfalls möglich. ■An emulsion is characterized in that it consists of 5% oil and 95% water is produced; another possible emulsion consists for example of 10% to 25% Oil and 90% to 75% water. Intermediate values are also possible. ■

Es sei erläutert, daß das Aufsprühen z.B. erstmals vor dem ersten Walzrollensatz (gegebenenfalls aber noch, weiter davor) erfolgt.It should be explained that the spraying is, for example, the first time before the first set of rolling rollers (but if necessary, further before).

Durch das erfindungsgemäße Verfahren ergeben sich erhebliche Vorteile. Die als Gleitmittel wirkende Emulsion ist nämlich gleichzeitig ein hervorragendes Kühlmittel und wirkt gerade dort, wo die größte Wärme durch Verformungsarbeit am Draht entsteht. Gleichzeitig werden die Rollen gekühlt und damit erheblich - auch wegen der sich damit einstellenden, besseren Gleitwirkung -geschönt, wodurch sich der Verschleiß, insbesondere für die RoI-The method according to the invention results in considerable Advantages. The emulsion, which acts as a lubricant, is at the same time an excellent coolant and works precisely where the greatest heat is generated by deformation work on the wire. At the same time, the Rolls cooled and thus considerably - also because of the themselves thus setting, better sliding effect -fined, whereby the wear, especially for the RoI-

Aber selbst beim Schweißen, sofern man die richtige Emulsion verwendet, ergeben sich bessere undzuverlässigere Schweißpunkte als bisher.But even with welding, if you use the right emulsion, you get better and more reliable results Welding points than before.

Vorzugsweise soll man ein relativ dünnflüssiges öl geringer Viskositätsklasse zur Anwendung bringen.Preferably one should use a relatively thin oil less Apply viscosity grade.

Es sei zum besseren Verständnis vorsorglich nochmals erläutert, daß das Besprühen unmittelbar, aber auch weiter davor, vor der ersten Walzrolle erfolgen kann, aber auch vor den nachfolgenden Walzrollen oder nur bei einer nachfolgenden Walzrolle.As a precautionary measure, it should be repeated for a better understanding explains that the spraying can take place immediately, but also further before, in front of the first roller, but also before the subsequent rolling rolls or only in the case of a subsequent rolling roll.
