Description

Maschensieb . Bei Sortier- und Klassierarbeiten kommen bekanntlich Maschensiebe zur Anwendung, welche aus Eisen- oder Nichteisenmetalldrähten bestehen. Handelt es sich um außerordentlich scharfkantiges, hartes Siebgut, so unterliegen diese Siebe einem sehr hohen Verschleiß. Da die Drahtsiebe teuer sind, wird hierdurch die Wirtschaftlichkeit wesentlich herabgedrückt.Mesh screen. As is well known, when sorting and classifying work Mesh screens for use, which consist of ferrous or non-ferrous metal wires. If it is extremely sharp-edged, hard material to be screened, they are subject to this these screens show a very high level of wear and tear. Since the wire screens are expensive, this will help the profitability significantly lowered.

Um 1 diesen Übelstand zu vermeiden, wird vorgeschlagen, zur Herstellung von Maschensieben an sich bekannten Verbundstahldraht beliebigen Querschnitts zu verwenden, wodurch eine außerordentlich hohe Verschleißfestigkeit gewährleistet ist. Der Verbundstahldraht besteht bekanntlich aus einer weichen, nicht härtbaren Seele und einem härtbaren Außenmantel. Die Härtung des V erbundstahldrahtes erfolgt zweckmäßig entweder nach vollständiger Herstellung des Siebes oder nach Herstellung einzelner Teile, weil der gehärtete Verbunddraht sich nicht mehr so gut verarbeiten läßt wie der ungehärtete. In order to avoid this inconvenience, it is proposed to use composite steel wire of any cross-section, known per se, for the production of mesh screens, which ensures extremely high wear resistance. As is known, the composite steel wire consists of a soft, non-hardenable core and a hardenable outer jacket. The hardening of the composite steel wire expediently takes place either after the sieve has been completely manufactured or after the manufacture of individual parts, because the hardened composite wire can no longer be processed as easily as the unhardened wire.

In der Zeichnung ist das Wesen der Erfindung beispielsweise veranschaulicht. Es bedeuten a die Querdrähte und b die Längsdrähte. Sowohl die Querdrähte als auch die Längsdrähte weisen eine weiche Seele m und einen harten Außenmantelh auf.In the drawing, the essence of the invention is illustrated for example. It means a the transverse wires and b the longitudinal wires. Both the transverse wires and the longitudinal wires have a soft core m and a hard outer jacket h.
