Die Erfindung bezieht sich auf ölhydraulisch getriebene Schmiedehämmer mit eingebautem Ölvorratsbehälter und einer ölkühleinrichtung. Es sind Maschinen dieser Art bekannt, die Leitungen zum Hindurchleiten von Kühlwasser durch den Ölsammelbehälter der Maschine besitzen. Die bei diesen Maschinen bekannten Ölkühler haben einen verhältnismäßig geringen Wirkungsgrad und halten den auftretenden Erschütterungen und Schwingungen nur kurze Zeit stand, so daß sie rasch zu Bruch gehen. Daher hat man bereits versucht, bei derartigen Schmiedehämmern auf eine besondere Ölkühleinrichtung ganz zu verzichten. Dadurch entstand jedoch der Nachteil, daß das Öl nicht mehr auf einer gleichmäßigen Temperatur während des Arbeitsvorganges gehalten werden kann.The invention relates to oil-hydraulically driven forging hammers with a built-in oil reservoir and an oil cooling device. There are machines of this type known, the lines to Have cooling water flowing through the machine's oil sump. The ones on these machines known oil coolers have a relatively low efficiency and keep the occurring Shocks and vibrations only stood for a short time, so that they break quickly. For this reason, attempts have already been made to use a special oil cooling device for such forging hammers to renounce entirely. However, this gave rise to the disadvantage that the oil was no longer on a constant temperature can be maintained during the work process.
Die Erfindung bezweckt, diese Nachteile zu beseitigen und außerdem weitere Vorteile zu erzielen, die in der Möglichkeit liegen, neben dem Kühlen gegebenenfalls mit der gleichen Einrichtung auch ein Erwärmen des Öles durchzuführen.The invention aims to eliminate these disadvantages and also to achieve further advantages, which are in the possibility of cooling, possibly with the same device as well To carry out heating of the oil.
Erfindungsgemäß wird vorgeschlagen, eine an sich bekannte, aus Flansch und Trägerrohr mit bifilar aufgewickeltem Kühlrohr bestehende Kühleinrichtung auswechselbar im ölvorratsbehälter anzuordnen. Hierdurch erhält man eine wirkungsvolle und leicht aus- und einbaubare Kühleinrichtung. Das Kühlrohr kann sich hier bei Wärmeschwankungen ungehindert ausdehnen und zusammenziehen.According to the invention it is proposed a known per se, comprising a flange and a support tube with a bifilar coiled cooling pipe existing cooling device to be arranged exchangeably in the oil reservoir. This results in an effective and easily removable and installable cooling device. The cooling pipe can expand and contract unhindered here in the event of heat fluctuations.
Bei der praktischen Ausführung ist die Kühleinrichtung in einem Gegenflansch gleitend gelagert. Dadurch erhält man die Möglichkeit, daß sich nicht nur das Kühlrohr, sondern auch das Trägerrohr bei Wärmeausdehnungen ungehindert verschieben kann. Das Trägerrohr kann gemäß einer weiteren Ausbildung der Erfindung gleichzeitig als Heizelement ausgebildet sein, beispielsweise zur Durchleitung von Dampf, Heißluft u. dgl. Vorzugsweise sind im Trägerrohr elektrische Widerstandsheizstäbe angeordnet, deren Anschluß an dem das Trägerrohr tragenden und mit ihm starr verbundenen Flansch sitzen kann. Damit die Widerstandsheizelemente gegen Schwingungen gesichert sind, werden sie in dem Trägerrohr mittels Aluminium eingegossen.In the practical version, the cooling device is slidably mounted in a counter flange. This gives the possibility that not only the cooling tube, but also the carrier tube at Can move thermal expansion unhindered. According to a further embodiment, the carrier tube can of the invention can also be designed as a heating element, for example for the passage of Steam, hot air and the like. Electrical resistance heating rods are preferably arranged in the support tube, their connection to the flange carrying the carrier tube and rigidly connected to it can sit. So that the resistance heating elements are secured against vibrations, they are in cast into the support tube using aluminum.
Es ist zwar bei Kühlvorrichtungen bzw. Wärmeaustauschvorrichtungen
bekannt, vom Kühlmittel bzw. Heizmittel durchströmte Rohrschlangen bifilar aufzuwickeln und auswechselbar in einem Behälter
anzuordnen. Derartige Einrichtungen hielt man jedoch bisher bei Schmiedehämmern für unbrauchbar,
da die bei derartigen Maschinen während des Betriebes auftretenden großen Erschütterungen nach

However, such devices have hitherto been considered unusable in forging hammers, since the large vibrations occurring in such machines during operation are also associated with the forging hammers driven by an oil-hydraulically driven forging hammers

Ansicht der Fachleute die frei hängenden und
besondere um eine horizontale Achse aufgewickelten Schlangen bald abbiegen oder gar abbrechen würden.
Daher hat man in ölhydraulisch getriebenen Schmiedeao hämmern bisher lediglich Kühlsysteme mit geringem
Wirkungsgrad vorgesehen, welche eingegossene Kühlkammern besitzen, deren Kühlwirkung nur zum Teil
ausgenutzt werden kann. Diese Kühlsysteme hielt man allein für ausreichend betriebssicher.
Durch die Erfindung wird dieses technische Vorurteil überwunden und ein neuer Weg zur Verbesserung
der Ölkühlung von Schmiedehämmern aufgezeigt. Durch die Anwendung der auswechselbaren,
in den Ölbehälter des Schmiedehammers ragenden Kühlschlangen ist es möglich, mit sehr geringem
Aufwand eine gleichmäßig niedrige Öltemperatur im Hammer zu erzielen. Die in den Ölbehälter ragenden,
waagerechten Kühlschlangen werden trotz der durch den Hammer erzielten starken Erschütterungen nicht
verbogen. Außerdem ergibt sich der Vorteil, daß die Ölkühleinrichtung leicht eingebaut und ausgewechselt
werden kann.Professionals view the free-hanging and
special snakes wound around a horizontal axis would soon bend or even break off. Therefore, hammers in oil-hydraulically driven forges have only been provided with low-efficiency cooling systems which have cast-in cooling chambers, the cooling effect of which can only be partially exploited. These cooling systems alone were considered to be sufficiently reliable.
The invention overcomes this technical prejudice and shows a new way of improving the oil cooling of forging hammers. By using the exchangeable cooling coils that protrude into the oil reservoir of the forging hammer, it is possible to achieve a uniformly low oil temperature in the hammer with very little effort. The horizontal cooling coils protruding into the oil container are not bent despite the strong vibrations caused by the hammer. In addition, there is the advantage that the oil cooling device can be easily installed and replaced.
