Description

Gesteinbohrer.Rock drill.

Zusatz zum Patent 398248.Addendum to patent 398248.

Im Patent 398248 ist ein Gesteinbohrer beschrieben, bei dem die Bohrer flügel Ausnehmungen haben, in denen die Schneiden aus Hartmetall liegen. Erfindungsgemäß werden diese Ausnehmungen so tief gemacht, daß die Schneidekanten sich möglichst einer Durchmesserlinie nähern. Gleichzeitig aber wird dafür1 Sorge getragen, daß zwischen den beiden Flügeln des Halters ein Verbindungsstück ;des Haltermaterials stehen bleibt, so daß also der Halter der Schneidenplättchen in einem zur Bohrerachse senkrechten Querschnitt eine Z- oder S-ähnliche Form erhält. Dadurch werden einesteils besonders günstige Arbeitsbedingungen für den Bohrer gewährleistet, andernteils erhalt der Bohrer sehr große Festigkeit und Leistungsfähigkeit. In der Zeichnung ist ein solcher Bohrer in Ansacht und im Schnitt dargestellt, a, b bezeichnen die in den Ausnehmungen liegenden Plattchen, c, d die die Plättchen tragienden Teile der Bohrerflügel, e das die beiden Bohrerflügel verbindende Mittelstück, durch das der Halter in dem dargestellten Fall im Schnitt eine Z-ähnliche Form bekommt. Es· ist insbesondere die B'ohrerform mit ebenen, zu der Achse geneigten Flügeln dargestellt, wie sie in dem Patent 399369 (Zusatz zum Patent 398248) beschrieben ist.In patent 398248 a rock drill is described in which the drill wing recesses in which the cutting edges are made of hard metal. According to the invention, these recesses are made so deep that the cutting edges approach a diameter line as closely as possible. At the same time 1, care is taken that a connecting piece between the two wings of the holder; remains of the holder material, so that therefore the holder of the cutting plate receives a Z- or S-like shape in a plane perpendicular to the axis of the drill cross-section. In this way, on the one hand, particularly favorable working conditions for the drill are guaranteed, and on the other hand, the drill has a very high level of strength and performance. In the drawing, such a drill is shown in perspective and in section, a, b denote the plates lying in the recesses, c, d the parts of the drill wings that carry the plates, e the middle piece connecting the two drill wings, through which the holder in the The case shown gets a Z-like shape in section. In particular, the drill shape is shown with flat wings inclined to the axis, as described in patent 399369 (addition to patent 398248).
