Abstract

Mechanically worked castings are mfd. At least two castings are connected by cast-on holding webs to form a unit; the webs are removed only after common mechanical working of the castings on the unit. Pref. the sprues serve as the webs. Method is partic. useful for small castings.

Description

Verfahren zum Herstellen von mechanisch bearbeiteten Gußstücken Die Erfindung betrifft ein Verfahren zum Herstellen von mechanisch bearbeiteten Gußstücken: Es ist seither üblich, die aus der Gießform entnommenen Gußstücke von anhaftenden Formresten zu befreien und anschliessend Gießtrichter und Gießläufe zu entfernen. Die einzelnen Gußstücke werden anschließend der notwendigen mechanischen Bearbeitung unterzogen. Insbesondere bei Gußstücken kleinerer Abmessungen bedingt die mechanische Bearbeitung einen relativ großen Aufwand an Nebenzeiten für das Ausrichten der Gußstücke. Method of Making Machined Castings Die The invention relates to a method for producing mechanically processed castings: Since then, it has been customary to remove adhering castings from the casting mold To free mold residues and then to remove pouring funnels and pouring runners. The individual castings are then subjected to the necessary mechanical processing subjected. In particular in the case of castings of smaller dimensions, the mechanical Machining a relatively large amount of non-productive time for aligning the castings.

Die Erfindung geht von der Uberlegung aus, daß die Nebenzeiten wesentlich verringert werden können, wenn man mehrere Gußstücke zu einer größeren Einheit zusammenfaßt und diese Einheit der mechanischen Bearbeitung unterwirft. Hierzu sind Haltestege vorgesehen, welche die einzelnen Gußstücke verbinden und nach dem letzten Arbeitsgang an der Einheit entfernt werden.The invention is based on the consideration that the non-productive times are essential can be reduced if you combine several castings into a larger unit and subjects this unit to mechanical processing. There are holding bars for this purpose provided, which connect the individual castings and after the last operation removed from the unit.

In der Zeichnung ist ein Anwendungsbeispiel dargestellt.An application example is shown in the drawing.

Die gezeigte Pleuelstange setzt sich aus den beiden Gußstükken 1 und 2 zusammen. Während nach herkömmlicher Methode die mit V V gekennzeichneten Flächen im getrennten Zustand der beiden Teile bearbeitet wurden, sind erfindungsgemäß die beiden Gußstücke 1 und 2 durch die Haltestege 5 und 4 zu einer Einheit verbunden, so daß in einem Einspannvorgang alle Flächen bearbeitet werden können. Die Haltestege 3 und 4 ersetzen in diesem Fall die sonst notwendigen Spannschrauben.The connecting rod shown consists of the two castings 1 and 2 together. While according to the conventional method, the areas marked with V V were processed in the separated state of the two parts, are according to the invention both castings 1 and 2 connected to one unit by the holding webs 5 and 4, so that in one clamping process all Surfaces can be edited. In this case, the holding bars 3 and 4 replace the otherwise necessary tensioning screws.

Nachdem die Bearbeitung der Einheit beendet ist, werden die Haltestege 3 und 4 entfernt und die beiden Teile sind montagefertig.After the processing of the unit is finished, the retaining webs 3 and 4 removed and the two parts are ready to assemble.

Der Erfindungsgedanke ist auf alle möglichen sonstigen Teile anwendbar und auch von der Art der mechanischen Bearbeitu* unabhängig. Auch ist es denkbar, daß das Eingußsystem, insbesondere die Gießläufe, als Haltestege im Sinne der Anmeldung dienen können.The idea of the invention is applicable to all possible other parts and also independent of the type of mechanical processing. It is also conceivable that the pouring system, in particular the pouring runners, as retaining webs within the meaning of the application can serve.
