Description

Größere Werkstücke, insbesondere Platten, lassen sich mittels Induktiver- Heizung insbiesonden e zum Härten an der Oberfläche dadurch erwärmen, daß sie an einem im Verhältnis zur Platte kleinen Induktor voirbeibew .egt werden. Zu diesem Zweck wurde bisher die Platte auf Walzen aufs Isolätions--rr@atexual--;gelegfi: -Bei dieser Ausführung muß an der. Plätxe-@emc Vorrrichtung zum Einbaken der Vorschübvorrichtung angebracht werden. Um diesem Übelstand abzuhelfen, wurde über die Rollen eine Kupfer- oder Messingplatte als Schlitten geführt, die mit der Vorschwbvörrichtung fest verbudden war. Dieseir Schlitten diente als Tragvorrichtung für tdme zu härtende Platte. Das '.hatte aber den, Nachteil, daß die Platte nur unter Zwischenschaltung von Isolationsstücken mit Odem Schlitten in Berührung kommen darf. Außerdem mußte die Rückleitung des Induktors in: großer Entfernung von .der Platte geführt werderi, .so. daß auch @ schon aus diesem Grunde die Verwendung seines Schlittens aus. nichtleitendem Werkstoff, wie Novotext, ausschalten mwßte. Dieser Werkstoff würde sich darüber hinaus aber .auch im zur Abschreckung :dienenden Wasserbad sehr stark verziehen, s6 daß eine einwandfreie Auflage der Platte nicht mehr' erfolgen würde.Larger workpieces, in particular plates, can be heated on the surface by means of inductive heating, in particular probes, for hardening, in that they are voirbeibew on an inductor which is small in relation to the plate. For this purpose, the plate has hitherto been on rollers on Isolätions - rr @ atexual -; occasfi: - In this version, the. Plätxe- @ emc device for hooking in the feed device. In order to remedy this inconvenience, a copper or brass plate was guided over the rollers as a slide, which was firmly connected to the Vorschwbvörrichtung. This carriage served as a support device for the plate to be hardened. But that had the "disadvantage" that the plate was only allowed to come into contact with the slide with the interposition of insulating pieces. In addition, the return line of the inductor had to be guided at a great distance from .the plate, .so. that @ for this reason alone from using his sled. would have to switch off non-conductive material, such as Novotext. In addition, this material would, however, also warp very strongly in the water bath used as a deterrent, s6 so that the plate would no longer be properly supported.

Alle diese Nachtehre werden nach der Erfindung dadurch beseitigt, daß: der Schlitten aus rostartigen Profilen hergestellt wird, die dumch isolierende Querverbndun gen zusammengehalten werden. Damit kann die Platte unmittelbar auf den Schlitten gelegt werden. Außerdem lern die Rückleitung -'des- Heizleiters, wenn man sie an den Broflen entsprechend abkr öpft, in unmittelbarer Nähe der Platte gefühlt weiden, so daß, die Streuung sehr klein g ehalten wird.According to the invention, all these detriments are eliminated by that: the slide is made of rust-like profiles, the dumch insulating Cross-connections are held together. This allows the plate to open immediately be placed on the sled. In addition, learn the return line -'des- heating conductor, if they are cranked at the breadcrumbs, in the immediate vicinity of the plate felt grazing, so that the spread is kept very small.

In der Zeichnung ist ein Ausfüihrungsb:eispiel dies Erfindungsgegenstandes dargestellt. Auf den Transportrollen i lauen die Profile a, die an den b#eiiden Enden über isolierende Querverbindungen miteinander verbunden sind. Wie der Zeichnung deutlich @entnehmbar ist, läßt sich nunmehr der Rückleiter 3 in iuimittelbazer Nähe der Platte q. entlangführen, sofern er in der Nähe der Profile z entsprechend abgekröpft wird.The drawing shows an example of this subject of the invention shown. The profiles a on the transport rollers i lean on the two Ends are connected to one another via insulating cross connections. Like the drawing is clearly visible, the return conductor 3 can now be in the vicinity the plate q. along, provided that it is correspondingly angled near the profile z will.

Der Antrieb für den Vorschub des Tragschlittens läßt such einfach .durch eine Zahnstange durchführen, :die beispielsweise in dass mittlere der drei gezeichneten Profile eingebaut wird. Gegenüber den Antrieben mittels Ziehen der Ketten ergibt sich bei der Ausführung mit Zahnstangen .eine kürzere Härtebank.The drive for the feed of the support carriage is easy . Carry out through a rack: the one in the middle of the three drawn profiles is installed. Compared to the drives by pulling the Chains with racks have a shorter hardness range.
