Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Vorbehandeln und/oder Beschichten der Lauffläche von einzelnen oder mehreren in einer Einheit zusammengefaßten Zylindern nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for pretreating and / or coating the tread of one or more cylinders combined in one unit according to the preamble of
Ein Verfahren zur Herstellung einer derartigen Laufflächenbeschichtung ist aus der DE-OS 39 37 763 bekannt. Dort wird einerseits der Zylinder, dessen Zylinderbohrungen beschichtet werden sollen, auf der Zylinderkopfseite mit einer Dichtungsplatte versehen und andererseits jedes Behandlungsbad mit einer Grundplatte, die die Zu- und Ablauf einrichtungen für die Badflüssigkeit aufweist, einer Pumpe und zugehöriger Steuerung bestückt. Zur Durchführung der Beschichtung wird der mit der Dichtungsplatte versehene Zylinder mit einer entsprechenden Transporteinrichtung zum jeweiligen Bad gebracht und dort auf die jeweilige Grundplatte aufgesetzt. Nachteilig an dieser Ausführung ist, daß jedes einzelne Bad mit gleichartigen Grundplatten, Pumpen und Steuerungen versehen sein muß.A method for producing such a tread coating is known from DE-OS 39 37 763. There, on the one hand, the cylinder, the cylinder bores of which are to be coated, is provided on the cylinder head side with a sealing plate and, on the other hand, each treatment bath is equipped with a base plate, which has the inlet and outlet devices for the bath liquid, a pump and associated control. To carry out the coating, the cylinder provided with the sealing plate is brought to the respective bath with a corresponding transport device and is placed there on the respective base plate. A disadvantage of this design is that each individual bath must be provided with the same base plates, pumps and controls.
Problem der vorliegenden Erfindung ist es daher, eine Vorrichtung zum Vorbehandeln und/oder zur Herstellung einer Laufflächenbeschichtung an Zylindern zu finden, die auf konstruktiv einfache Weise eine kostengünstige Vorbehandlung und/oder Beschichtung der Laufflächen von Zylinderbohrungen im Durchflußverfahren gewährleistet, wobei die einzelnen Behandlungsflüssigkeiten konventionell in Form einer Badreihe zur Anwendung kommen.The problem of the present invention is therefore to find a device for pretreating and / or for producing a tread coating on cylinders that is based on structurally simple way a cost-effective pretreatment and / or coating of the running surfaces of cylinder bores in the flow method is guaranteed, the individual treatment liquids being used conventionally in the form of a row of baths.
Die Lösung dieses Problems wird erreicht mit einer Vorrichtung mit den Merkmalen nach dem Kennzeichen des Anspruchs 1.The solution to this problem is achieved with a device with the features according to the characterizing part of
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen enthalten.Advantageous embodiments of the invention are contained in the subclaims.
Ein Ausführungsbeispiel wird anhand der Zeichnung, gemäß Fig. 1, die eine schematisierte Ansicht der Vorrichtung darstellt, nachstehend näher erläutert.An exemplary embodiment is explained in more detail below with reference to the drawing according to FIG. 1, which represents a schematic view of the device.
Eine Vorrichtung zum Vorbehandeln und/oder zur Herstellung einer Laufflächenbeschichtung an Zylindern von Verbrennungsmotoren durch Abscheidung einer Laufschicht aus Beschichtungsbädern, hier einer Nickelsiliziumcarbidschicht, besteht aus einer Vorrichtung 1 mit einer Grundplatte 2, auf deren Aufnahmefläche 3 ein Zylinder (nicht gezeichnet) mit seiner Zylinderkopfseite dichtend aufliegt. Entsprechend der Anzahl der zu beschichtenden Zylinderbohrungen besitzt die Grundplatte 2 Zulauföffnungen 4 und Standrohre 5 mit Ablaufbohrungen 6. Die jeweilige Badflüssigkeit wird über ein Verteilerrohr 7 und entsprechende Leitungen 8 den Zulauföffnungen 4 zugeführt, nachdem sie über eine in die Grundplatte 1 integrierte Pumpe 9 und angeschlossenes Saugrohr 10 dem Badbehälter (nicht gezeichnet) entnommen wurde. Für den Transport der Grundplatte 2 ist diese mit an sich üblichen und bekannten Aufhängungen (nicht gezeichnet) verbunden, über die auch die Stromzuführung für die Pumpe erfolgen kann.A device for pretreating and / or for producing a tread coating on cylinders of internal combustion engines by depositing a running layer from coating baths, here a nickel silicon carbide layer, consists of a
Zur Durchführung des eigentlichen Beschichtungsvorganges sind die Standrohre 5 aus bekannten Anoden-Metallen hergestellt und mit elektrischen Zuleitungen verbunden.To carry out the actual coating process, the
Um Verschleppungen von Badflüssigkeit beim Umsetzen von einem Badbehälter zum nächsten weitgehend zu vermeiden, ist eine Ablaufleitung 11 vorgesehen, die über ein Ventil 12 geöffnet bzw. geschlossen werden kann.In order to largely avoid carryover of bath liquid when moving from one bath container to the next, a
Mit einer derartigen Ausführung zur Durchflußbeschichtung, bei der der Zylinder mit seiner Zylinderkopfseite direkt dichtend auf der Grundplatte 1 aufliegt und die Zylinderbohrungen mit den entsprechenden Zu- und Ablaufeinrichtungen 4 - 6 für die Badflüssigkeit in Verbindung gebracht werden, wobei die Grundplatte 1 mittels ihrer Transportaufhängung von einem zum anderen Bad bewegt und dort einfach nur so auf den Badbehälter aufgesetzt wird, daß das Saugrohr 10 in die Badflüssigkeit reicht, ist auf konstruktiv einfache Weise eine Vorrichtung 1 geschaffen, die ohne zusätzliche gleichartige Einzelelemente an den jeweiligen Badvorrichtungen eine kostengünstige Beschichtung bzw. Spülung oder Reinigung gewährleistet, da diese Elemente nur einmal vorgesehen in der Grundplatte 2 integriert sind.With such a design for flow coating, in which the cylinder rests with its cylinder head side sealingly on the
