Abstract

Disc cutter for rock drills, boring tools etc., forms one of several discs mounted on a rotary plate serving as tooling for the machine. The annular body (10) of the disc has a peripheral groove (14) for a number of evenly spaced cutters (16) which are each brazed into the groove for securement purposes. Preferably the intervening spaces between the cutters in their mounting groove should be filled with filler substance. These fillers, suggestibly though not specified made from molten steel, form spacers between the individual cutters forming the disc edge and at the same time prevent drillings or abrasives from penetrating the groove areas between the cutters.

Description

Schneidrolle flir eine Gesteinsbohrmaschine Die Erfindung betrifft eine Schneidrolle filr eine Gesteinsbohrmaschine, Diese Maschinen weisen im allgemeinen mehrere Schneidrollen auf, die auf der Stirnfläche einer drehbaren Kopfplatte gelagert sind; diese Maschinen werden tiblicherweise zum Bohren in Fels verwendet.Cutter for a rock drilling machine The invention relates to a cutter roll for a rock drilling machine. These machines generally have several cutting rollers, which are mounted on the end face of a rotatable head plate are; these machines are commonly used for drilling into rock.

Ziel der Erfindung ist es, eine verbesserte Schneidrolle der genannten Art zu schaffen.The aim of the invention is to provide an improved cutting roller of the aforesaid Kind of creating.

Die erfindungsgemäße Schneidrolle weist einen ringförmigen Körper auf, eine sich um den Umgang des Körpers erstreckende kontinuierliche Nut und mehrere in gleichmäßigen Abständen in der Nut angeordnete und sich längs dieser erstreckende Schneidelemente, die jeweils in die Nut eingelötet sind.The cutting roller according to the invention has an annular body on, one continuous groove extending around the perimeter of the body and several arranged at regular intervals in the groove and extending along this Cutting elements, each soldered into the groove.

In Weiterbildung des Erfindungsgedankens ist vorgesehen, daß die Zwischenräume zwischen benachbarten Schneidelementen in der Nut mit einem Ftlllmaterial gefiillt sind.In a further development of the inventive concept it is provided that the spaces between adjacent cutting elements in the groove filled with a filling material are.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels, das in der Zeichnung dargestellt ist, näher erläutert.The invention is explained below using an exemplary embodiment, which is shown in the drawing, explained in more detail.

Es zeigen: Fig. 1 eine erfindungsgemäße Schneidrolle im Längsschnitt, Fig. 2 eine Seitenansicht der Schneidrolle und Fig. 3 eine Stirnansicht einer drehbaren Kopfplatte, auf der die Schneidrollen gelagert sind.1 shows a cutting roller according to the invention in longitudinal section, FIG. 2 shows a side view of the cutting roller and FIG. 3 shows an end view of a rotatable one Head plate on which the cutting rollers are mounted.

Die in den Fig. 1 und 2 dargestellte Schneidrolle gemäß der Erfindung weist einen ringförmigen Körper 10 aus Stahl oder ähnlichem Material auf, der drehbar auf einer Welle 12 gelagert ist. Eine kontinuierliche Ausnehmung oder Nut 14 ist am Umfang des Körpers 10 ausgebildet; eine Reihe von bogenförmigen Schneidelementen 16 aus Hartmetall ist in der Nut 14 und entlang dieser angeordnet und darin eingelötet. Die Schneidelemente 16 sind in gleichmäßigen Abständen um den Umfang des Körpers verteilt; die Zwischenräume 18 zwischen benachbarten Schneidelementen liegen vorzugsweise in der Größenordnung von 6,5 mm.The cutting roller shown in FIGS. 1 and 2 according to the invention comprises an annular body 10 made of steel or similar material which is rotatable is mounted on a shaft 12. A continuous recess or groove 14 is formed on the periphery of the body 10; a series of arcuate cutting elements 16 made of hard metal is arranged in the groove 14 and along this and soldered therein. The cutting elements 16 are evenly spaced around the circumference of the body distributed; the spaces 18 between adjacent cutting elements are preferably located on the order of 6.5 mm.

Zum Einleiten der Schweiflelemente in die Ausnehmung wird ein Streifen 20 einer geeigneten Lötlegierung in der Nut 14 unter jedem Schneidelement 16 angeordnete Perforierte Abstandsstücke 22 aus Stahl werden in der Nut auf beiden Seiten des einzulötenden Schneidelementes angebracht, um das Element zu zentrieren und die Lötspaltbreite zu bestimmen. Auf das äußere Ende des Schneidelements wird dann ein radial nach innen gerichteter Druck aufgebracht mittels einer Feder oder dergleichen und die Baugruppe wird dann erhitzt, beispielsweise durch Induktionserhitzung. Die Lötlegierung 20 schmilzt und ein Teil davon wird infolge des Federdrucks an den Seiten der Nut nach oben gedrückt und verbindet die Seiten des Schneidelements mit den Seiten der Nut durch die perforierten Abstands stücke hindurch.A strip is used to introduce the tail elements into the recess 20 of a suitable solder alloy arranged in the groove 14 under each cutting element 16 Perforated steel spacers 22 are placed in the groove on either side of the to be soldered cutting element attached to center the element and the To determine the width of the soldering gap. On the outer end of the cutting element is then a radially inward pressure applied by means of a spring or the like and the assembly is then heated, for example by induction heating. the Solder alloy 20 melts and part of it is applied to the Sides of the groove pushed up and connects the sides of the cutting element with the pages of the Groove through the perforated spacers.

Jedes Schneidelement 16 ist vorzugsweise ungefähr 65 mm lang.Each cutting element 16 is preferably approximately 65 mm long.

Ein geeignetes Füllmaterial, wie beispielsweise flüssiger Stahl, wird in die Nut zwischen benachbarte Schneidelemente eingebracht, um als Zwischenstück zu wirken und zu verhindern, daß Gesteinsstücke in den Zwischenräumen eingeklemmt werden.A suitable filler material, such as liquid steel, is introduced into the groove between adjacent cutting elements to act as an intermediate piece to act and to prevent pieces of rock from getting jammed in the gaps will.

Fig. 3 zeigt mehrere Schneidrollen gemäß der Erfindung, die auf der Stirnfläche einer drehbaren Kopfplatte gelagert sind.Fig. 3 shows several cutting rollers according to the invention, which on the End face of a rotatable head plate are mounted.

Aus Gründen der einfacheren Darstellung ist nur eine einzige Schneidrolle 24 in Einzelheiten dargestellt.For the sake of simplicity of illustration there is only a single cutting roller 24 shown in detail.
