Abstract

Der erfindungsgemäße Schneidkopf weist zunächst einen Schneidkopfkern (07) und mehrere Meißelhalter (08) auf. Erfindungsgemäß bestehen der Schneidkopfkern (07) und zumindest mehrere der Meißelhalter (08) aus einem einzigen Gusswerkstück (02). Das erfindungsgemäße Verfahren zur Herstellung eines Schneidkopfes umfasst zunächst einen Schritt zur Bereitstellung einer Gussform (01) zum Gießen eines Schneidkopfkerns (07) mit mehreren Meißelhaltern (08). In einem nächsten Schritt wird die Gussform (01) mit einem Gusswerkstoff ausgegossen. Anschließend kommt es zu einem Erstarren des Gusswerkstoffes, sodass ein festes Gusswerkstück (02) ausgebildet wird. Dieses Gusswerkstück (02) bildet den Schneidkopfkern (07) mit den Meißelhaltern (08) aus. Der Schneidkopfkern (07) und die gegossenen Meißelhalter (08) sind somit durch ein einziges Gusswerkstück (02) gebildet. Schließlich erfolgt ein Entformen des Gusswerkstückes (02), bei welchem die Gussform (01) vom Gusswerkstück (02) entfernt wird.

The cutting head according to the invention initially has a cutting head core (07) and a plurality of chisel holders (08). According to the invention, the cutting head core (07) and at least several of the bit holders (08) consist of a single cast workpiece (02). The method according to the invention for producing a cutting head initially comprises a step for providing a casting mold (01) for casting a cutting head core (07) with a plurality of bit holders (08). In a next step, the casting mold (01) is poured out with a casting material. Subsequently, a solidification of the cast material, so that a solid cast workpiece (02) is formed. This casting work piece (02) forms the cutting head core (07) with the chisel holders (08). The cutting head core (07) and the cast chisel holder (08) are thus formed by a single cast workpiece (02). Finally, a demolding of the cast workpiece (02) takes place, in which the casting mold (01) is removed from the cast workpiece (02).
