Description

Verfahren zur Erzielung großer Trägheits- und Widerstandsmomente von Gußkörpern. Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Erzielung großer Trägheits- und '\Viderstandsmomente von Gußkörpern, wie solche im Maschinenbau zur Anwendung gelangen. Wie bekannt, ist die Anbringung von Durchbrechungen in den Wänden von gegossenen Hohlkörpern unb =-dingt erforderlich, sei es, daß solche Durchbrechungen als Kernlöcher zur Anbringung von Kernstützen, als Kernlöcher zum nachträglichen Entfernen des Kernes oder auch als Luftlöcher zum Abziehen der sich während des Gusses bildenden Gase ausgebildet sind. Diese .Durchbrechungen in den Gußwänden bilden mehr oder minder eine Schwächung des Hohlkörpers und machen sich besonders dann bemerkbar, wenn die Körper auf Biegung, Verdrehung, Biegung und Verdrehung oder in anderer Weise beansprucht werden. Insbesondere tritt die Schädlichkeit der Durchbrechungen in Erscheinung, wenn der Körper auf Verdrehen beansprucht wird.Method for achieving large moments of inertia and resistance of Cast bodies. The present invention relates to a method for achieving this large moments of inertia and resistance of cast bodies, such as those in mechanical engineering come into use. As is known, the installation of perforations in the Walls of cast hollow bodies are absolutely necessary, be it that such breakthroughs as core holes for attaching core supports, as core holes for subsequent Removal of the core or also as air holes to pull off the during the Gusses forming gases are formed. These breakthroughs in the cast walls form more or less a weakening of the hollow body and make themselves special then noticeable when the body is on bend, twist, bend and twist or otherwise claimed. In particular, the harmfulness of the Breakthroughs appear when the body is subjected to twisting.

Zweck der vorliegenden Erfindung ist es, die Trägheits- und Widerstandsmomente des Gußstückes zu erhöhen. Es wird dies dadurch erreicht, daß die Durchbrechungen der Wandungen mit Füllstücken geschlossen und diese durch Verschweißen mit dem Hohlkörper innig verbunden werden, so daß der Körper mit dem Füllstück als ein homogenes Stück betrachtet werden kann. Zweckmäßig ist es hierbei, nach dem Schweißen das Gußstück noch einmal zu glühen, um die durch das Schweißen entstandenen Spannungen im GuPstück zu vernichten. Bei der Ausübung des Verfahrens ist es gleichgültig und hat auf die vorliegende Erfindung keine Einwirkung, ob das Füllstück die gleiche Materialzusammensetzung zeigt wie der Gußkörper selbst oder ob im Interesse der leichten Schweißbarkeit eine andre Zusammensetzung gewählt wird. Ferner ist es ohne Belang, wie die Art der Schweißung, ob elektrisch oder autogen, vorgenommen wird. Weiterhin können die Schweißkanten beliebig ausgeführt sein, d. h. das Einlagestück kann beispielsweise mit dem Gußkörper stumpf verschweißt werden, oder es kann auch die Schweißnaht schwalbenschwanzförmig vorgearbeitet sein, ohne an der Erfindung etwas zu ändern.The purpose of the present invention is to measure the moments of inertia and resistance to increase the casting. This is achieved in that the openings the walls are closed with filler pieces and these are welded to the hollow body are intimately connected so that the body with the filler piece as a homogeneous piece can be viewed. It is useful here, after welding, the casting to glow again to relieve the stresses in the GuP piece caused by the welding to destroy. In the exercise of the procedure it is indifferent and has to be on the present invention does not affect whether the filler piece has the same material composition shows how the cast body itself or whether in the interest of easy weldability another composition is chosen. Furthermore, it is irrelevant how Art the welding, whether electric or autogenous, is carried out. Furthermore, the Weld edges can be designed as desired, d. H. the insert can, for example be butt-welded to the cast body, or the weld seam can also be dovetail-shaped be prepared without changing anything in the invention.
