Description

Das Formen von freiliegenden Stegen auf Gußstücken bereitete bisher besonders dann erhebliche Schwierigkeiten, wenn es sich um eine größere Anzahl handelte, die miteinander nicht verbunden waren, und die, obwohl zu mehreren in einer Flucht liegend, ihre Richtung mehrfach wechselten, wie dies bei den Stegen der in Abb. ι beispielsweise dargestellten Lagerschale der Fall ist. Man war bisher gezwungen,The shaping of exposed webs on castings has been particularly difficult in the past considerable difficulties when it was a question of a large number of people working together were not connected, and although several of them were in alignment, their direction changed several times, as is the case with the webs of the bearing shell shown in Fig. ι, for example the case is. Up until now one was forced to

ίο erst den ganzen Kern freizulegen und dann den Formteil jedes einzelnen Steges für sich vorsichtig aus dem Sande herauszuziehen. Diese zeitraubende und große Geschicklichkeit erfordernde Formweise macht die vorliegende Erfindung entbehrlich, indem alle in einer Flucht liegenden Stege durch ein gemeinsames Modellteil <i aus biegsamem Werkstoff im Durchzugverfahren geformt werden.
Um beispielsweise den Kern des in Abb. ι dargestellten Gegenstandes zu formen, wird ein Kernkasten nach den Abb. 2 bis 4 angefertigt. Dieser besteht aus der Grundform a, den Ringen b, den Brücken c und den Seitenbrettern f. Das Wesentliche der vorliegenden Erfindung ist nun die Verwendung von Modellteilen d aus einem biegsamen Material, z. B. Leder, Gewebe 0. dgl., zur Formgebung der in Abb. ι ersichtlichen Stege e. Wie aus Abb. 2 ersichtlich, sind diese biegsamen Modellteile d durch die Grundform α hindurchgeführt; sie können auf der Rückseite irgendwie angespannt und befestigt werden. Nach dem Einstampfen können diese Modellteile d ohne jede Vorsicht nach einer Seite herausgezogen werden. Alsdann werden noch die Ringe b herausgedreht, die Brücken c und die Bretter f entfernt und der Kasten a umgelegt und abgehoben. Der sehr komplizierte Kern ist auf diese Weise ohne jede Vorsicht fehlerlos in wenigen Minuten hergestellt.
ίο first to expose the entire core and then carefully pull the molded part of each individual bar out of the sand. This form, which is time-consuming and requires great skill, makes the present invention dispensable, in that all of the webs lying in alignment are formed by a common model part made of flexible material in a pull-through process.
For example, in order to shape the core of the object shown in Fig. Ι, a core box according to Figs. 2 to 4 is made. This consists of the basic shape a, the rings b, the bridges c and the side boards f. The essence of the present invention is the use of model parts d made of a flexible material, e.g. B. leather, fabric 0. The like. To shape the webs shown in Fig. Ι e. As can be seen from Fig. 2, these flexible model parts d are passed through the basic shape α ; they can be stretched and fastened somehow on the back. After crushing, these model parts d can be pulled out to one side without any care. Then the rings b are unscrewed, the bridges c and the boards f removed and the box a turned over and lifted off. In this way, the very complicated core can be produced flawlessly in a few minutes without any precaution.

Patentanspruch :Claim: Aus biegsamem Werkstoff hergestellter Modellteil zum Abformen von freiliegenden Stegen auf dem Gußstück, besonders von Stegen auf der Innenseite von Lagerschalen, dadurch gekennzeichnet, daß die Stegmodelle aus biegsamem, aber nicht dehnbarem Werkstoff, z. B. Leder, bestehen, so daß sie auch bei einem Richtungswechsel im Durchzugverfahren aus der aufgestampften Form herausziehbar sind.Model part made from flexible material for molding exposed parts Webs on the casting, especially webs on the inside of bearing shells, characterized in that the bar models are made of flexible, but not stretchable material, z. B. leather, exist, so that they even with a change of direction in the pull-through process can be pulled out of the stamped-on form. Hierzu 1 Blatt Zeichnungen1 sheet of drawings
