Zum Einbringen von Einpresselementen in ein Bauteil, bspw. in ein Gussteil oder einen Gussknoten, ist eine bestimmte Lochvorbereitung erforderlich, um im verpressten Zustand des Einpresselements eine ebene Montagefläche zu erhalten, die eine definierte Montage eines weiteren Bauteils erlaubt. Zusätzlich muss das eingepresste Element für die Befestigung das erforderliche Anzugsmoment aufnehmen können. Dies erfordert einen erhöhten Aufwand, insbesondere ist aus Entformgründen ein Schieber im Werkzeug erforderlich. Dies erhöht jedoch die Werkzeugkosten und die Zykluszeit zur Herstellung des Bauteils, mit der Folge, dass dadurch auch die Kosten des Bauteils ansteigen.there the joining takes place and pressing in a tool, for example. Follower tool with stamp and Die, wherein in the component by mechanical machining the pre-hole is produced. For introducing press-fit elements into a component, For example, in a casting or a cast node, is a specific Hole preparation required in the pressed state of the press-fit element a flat mounting surface to obtain a defined assembly of another component allowed. additionally must be the pressed element for the attachment can take the required torque. This requires an elevated one Expenditure, in particular, is a slide in the tool for Entformgründen required. This increases However, the tooling costs and the cycle time for the production of the Component, with the result that thereby increase the cost of the component.
Aufgabe der Erfindung ist es daher, ein Verfahren zum Einpressen eines hülsenförmigen Einpresselements in eine Fügeöffnung eines Bauteils anzugeben, mit dem ein einfaches und damit auch kostengünstiges Einbringen von Einpressteilen in Bauteile, vorzugsweise in Gussteile möglich ist, insbesondere soll dieses Verfahren leicht in einen Fertigungsprozess mit geringer Prozessanfälligkeit integrierbar sein und die oben genannten Nachteile vermeiden.task The invention is therefore a method for pressing a sleeve-shaped press-in element in a joint opening of a Specify component, with a simple and therefore cost-effective Introducing Einpressteilen in components, preferably in castings possible In particular, this process is intended to easily enter a manufacturing process with low process vulnerability be integrable and avoid the above-mentioned disadvantages.
Diese Aufgabe wird gelöst durch ein Verfahren mit den Merkmalen des Patentanspruchs 1.These Task is solved by a method having the features of patent claim 1.
Bei einem solchen Verfahren zum Einpressen eines hülsenförmigen Einpresselements in eine Fügeöffnung eines Bauteils, bei dem nach dem Fügen des Einpresselements in die Fügeöffnung die Stirnfläche eines Fügeabschnitts des Einpresselements mit einer Oberflächenseite des Bauteils korrespondiert und eine Schulterfläche eines umlaufenden Flansches des Einpresselements gegen die andere Oberflächenseite des Bauteils anliegt, und durch anschließende plastische Materialverformung unter Anwendung einer Matrize, in der das Einpresselement mit dem Bauteil gehalten wird, und eines beweglich geführten Stempels das Einpresselement in dem Bauteil verankert wird, ist erfindungsgemäß vorgesehen, dass zunächst vor dem Fügen des Einpresselements in die Fügeöffnung stempelseitig diese mit einer Anfasung versehen wird, ein Einpresselement verwendet wird, dessen Fügeabschnitt höchstens der Dicke des Bauteils im Bereich der Fügeöffnung entspricht und zum Verpressen des Fügeabschnitts durch Versenken in die Fügeöffnung sowie zum Verpressen der Stirnfläche des Fügeabschnitts in die Anfasung der Fügeöffnung das mit dem Fügeabschnitt zusammenwirkende Ende des Stempels als Kugelschicht mit einer Kugelzone ausgebildet ist.at Such a method for pressing a sleeve-shaped press-in in a joint opening of a Component in which after joining of the press-in element in the joining opening, the end face of a Add section of the press-in element corresponds to a surface side of the component and a shoulder surface a circumferential flange of the press-in element against the other surface side of the component is applied, and by subsequent plastic deformation under Application of a die, in which the press-in element with the component is held, and a movably guided punch the press-fit is anchored in the component, the invention provides that initially before the joining of the press-in element in the joining opening on the punch side this is provided with a chamfer, a press-fit used whose joining section is at most the Thickness of the component in the region of the joint opening corresponds to and for pressing of the joining section Sinking into the joint opening as well for pressing the end face of the joining section in the chamfer of the joint opening the cooperating with the joining section End of the stamp formed as a spherical layer with a spherical zone is.
