Abstract

Connecting rod blanks for i.c. engines are mfd. as a strand, from which individual blanks are separated. The strand forming process can be a pressing or continuous casting process. The connecting rod blank can include the bearing cap which is afterwards removed. Individual blanks are separated with a laser beam or fluid stream. ADVANTAGE - Economical mass prodn.

Description

Die Erfindung betrifft ein Verfahren zum Fertigen eines Pleuels, insbesondere eines Pleuel-Rohlings für eine Brennkraftmaschine.The invention relates to a method for manufacturing a Connecting rods, in particular a connecting rod blank for one Internal combustion engine.

Nach bekannten Fertigungsverfahren werden Pleuel aus einem Grundwerkstoff in mehreren Stufenwerkzeugen separat zum endgültigen Rohteil verarbeitet. Bekannt sind gegossene, geschmiedete oder auch gesinterte Pleuel. Erforderlich sind hierbei zumeist mehrere Werkzeuge, die kontinuierlich beschickt werden müssen, wobei mit Ausnahme mehrerer in einer Form nebeneinander angeordneter Pleuel jeder Pleuelrohling quasi separat hergestellt wird.Connecting rods are made from known manufacturing processes a base material in several step tools processed separately to the final raw part. Known are cast, forged or sintered Connecting rod. Usually several are required Tools that need to be fed continuously with the exception of several in a form side by side arranged connecting rod each connecting rod blank quasi separately will be produced.

Ein demgegenüber wirtschaftlicheres Fertigungsverfahren insbesondere für die Großserienfertigung aufzuzeigen, hat sich die Erfindung zur Aufgabe gestellt.In contrast, a more economical manufacturing process especially for large-scale production, the invention has set itself the task.

Zur Lösung dieser Aufgabe ist vorgesehen, daß mehrere Pleuel an ihren Stirnseiten zusammenhängend in einem Strang-Formverfahren geformt und anschließend voneinan­ der getrennt werden.To solve this problem it is provided that several Connecting rods on their end faces connected in one Strand molding process shaped and then from one another who are separated.

Als derartiges Strang-Formverfahren kann ein an sich bekanntes Strang-Preßverfahren (beispielsweise für Sinterwerkstoffe) oder ein Strang-Gußverfahren zum Einsatz kommen. Von dem aus der Werkzeugmaschine aus­ tretenden quasi endlosen Formstrang können die einzelnen Pleuelrohlinge in entsprechend gewünschter Dicke einfach abgeschnitten werden. Als bevorzugtes Trennwerkzeug kommt hierbei ein Laser- oder Wasserstrahl zum Einsatz. Es ist aber auch möglich, vor dem Abtrennen der einzel­ nen Pleuel die Seitenflächen oder inneren Flächen der Pleuelrohlinge am Formstrang zumindest teilweise zu bearbeiten.As such, a strand molding process can be used as such known extrusion process (for example for Sintered materials) or a continuous casting process for  Come into play. From the machine tool The individual can enter the almost endless strand of form Connecting rod blanks in the desired thickness are simple be cut off. As a preferred cutting tool a laser or water jet is used. But it is also possible to separate the individual conrods the side faces or inner faces of the Connecting rod blanks on the molded strand at least partially to edit.

Vorzugsweise eignet sich die Erfindung auch zur Ferti­ gung von Pleuel-Rohlingen, deren Lagerdeckel an den Pleuelgrundkörper angeformt sind. Bekannt ist es hierfür beispielsweise, die Lagerdeckel vom Pleuelgrundkörper durch sog. Cracken abzutrennen. Vorteilhafterweise ist dieser Crackvorgang bei erfindungsgemäß gefertigten Pleueln auch an einem Formstrang mit mehreren an ihren Stirnseiten noch zusammenhängenden Pleueln durchführbar.The invention is preferably also suitable for production of connecting rod blanks, the bearing caps on the Connecting rod base bodies are molded on. It is known for this for example, the bearing caps from the connecting rod base separated by so-called cracking. It is advantageous this cracking process in manufactured according to the invention Connecting rods on one strand with several on theirs Front ends of connecting rods still connected.

Ein Ausführungsbeispiel für die Erfindung ist nicht gezeigt, das es anhand obiger Erläuterungen dem Fachmann möglich sein müßte, ein Pleuel nach einem erfindungsge­ mäßen Verfahren zu fertigen. Dieses Verfahren zeigt dabei an Großserienteilen, wie Pleueln von Brennkraft­ maschinen, besondere Vorteile, da Pleuel aufgrund ihrer Form für ein derartiges Fertigungsverfahren besonders geeignet sind.An embodiment of the invention is not shown that it is based on the above explanations to the expert it should be possible to use a connecting rod according to the invention according to the process. This procedure shows thereby on large series parts, such as connecting rods of internal combustion machines, special advantages because of connecting rods due to their Form for such a manufacturing process especially are suitable.
