Description
Die Neuerung betrifft eine Einrichtung zum Härten von Werkstücken, die im Abschreckbad induktiv erhitzt werden, wobei dessen Abschreckflüssigkeit laufend umgepumpt wird.The innovation concerns a device for hardening workpieces, which are inductively heated in the quenching bath, the quenching liquid of which is continuously pumped around.
Es ist an sich bekannt, vor allem größere Werkstücke, wie Maschinenteile u.dgl. zur Erzielung einer gleichmäßigen Härteschicht unmittelbar in der Kühlflüssigkeit induktiv zu erhitzen, so daß nach dem Abschalten der induktiven Erwärmungseinrichtung das Werkstück sofort gekühlt und gehärtet wird. Da die induktive Erwärmung eine verhältnismäßig rasche E:hitzung des zu härtenden Gegenstandes zur Folge hat, kann mit befriedigendem Erfolg die geforderte Härte erzielt werden, jedoch hat dieses Verfahren in sofern einen Nachteil, als an der heißen Werkstückoberfläche Dampf- bzw. Gasschichten bzw. -blasen auftreten, die den Zugang des Härte- bzw. Kühlmittels zur Werkstückoberfläche an dieser Stelle hindern·. Dadurch entstehen weiche Flecken auf der Werkstückoberfläche, die unerwünscht bzw. in den meisten Fällen sogar unzulässig sind. Bei dünnen Drähten, die im Durchlauf durch das Bad geführt vierden, tritt diese Erscheinung kaum auf. Sie macht sich jedoch sehr nachteilig bei WerkstückenIt is known per se, especially larger workpieces, such as machine parts To achieve a uniform hardness layer to be inductively heated directly in the cooling liquid, so that after when the inductive heating device is switched off, the workpiece is immediately cooled and hardened. Since inductive heating is a relatively rapid E: heating of the object to be hardened for Result, the required hardness can be achieved with satisfactory success, but this method has a disadvantage insofar as than vapor or gas layers or layers on the hot workpiece surface. - bubbles occur which prevent the hardening or coolant from accessing the workpiece surface at this point. This creates soft spots on the workpiece surface, which are undesirable or in most cases even inadmissible. With thin wires that This phenomenon occurs when it is passed through the bath hardly open. However, it is very disadvantageous for workpieces

Die Erfindung hat die Aufgabe, eine Einrichtung zum Harten von Werkstücken zu schaffen, bei der ebenfalls die zu härtenden Werkstücke im abschreckenden Bad erhitzt werden, jedöqh eine Weichfleckigkeit sicher vermieden wird.larger dimensions noticeable. The invention has the task of creating a device for hardening workpieces, in which also the workpieces to be hardened are heated in the quenching bath, but soft spots are reliably avoided.
