Die Erfindung betrifft eine in radialer Richtung wirkende Spanneinrichtung für eine wendelförmig gewickelte, in Längs= richtung festgelegte und vorzugsweise mit Metzfrequenz ge= speiste wassergekühlte Induktionsspule zum Erhitzen von durch sie hindurch zu bewegende Rechteckblöcke.The invention relates to a radial direction Clamping device for a helically wound, fixed in the longitudinal direction and preferably with Metz frequency ge = fed water-cooled induction coil for heating rectangular blocks to be moved through it.
Bei einer solchen Spule treten während des Betriebes im Rhyth= mus der Periodenzahl des Wechselstromes unter starker Geräusch= bildung Vibrationen auf. Durch diese entstehen in den geraden Abschnitten der einzelnen Spulenwindungen stark nach außen gerichtete mechanische Kräfte, die im Betrieb zu einer Quer= Schnittsveränderung der Spule führen, wenn diese nicht in einem kräftigen Haltegrüst aufgenommen ist. Dabei wird durch Aneinanderreihen der benachbarten Windungen deren Isolierung bald zerstört. Damit wird die Spule unbrauchbar.With such a coil, the rhythm = mus is the number of periods of alternating current under strong noise = formation of vibrations. This creates a strong outward direction in the straight sections of the individual coil turns Directed mechanical forces that lead to a change in the transverse section of the coil during operation if it is not in is added to a sturdy support structure. The insulation of the adjacent turns is thereby achieved by lining up the adjacent turns soon destroyed. This renders the coil unusable.
Um diese Mangel zu vermindern, hat man bereits die geraden ι sich parallel gegenüberliegenden flachen Abschnitte der einzelnen! Windungen außen an in Längsrichtung zur Flachspule fest ange= ' ordneten lattenförmigen, nichtleitenden Haltern abgestützt oder aber diese mit den einzelnen Windungen der Spule unter Verwendung von bekannten Verbxndungsmitteln, wie Schrauben und Muttern vereinigt.In order to reduce this deficiency, one already has the straight ι parallel opposite flat sections of each! The outer windings are supported on slatted, non-conductive holders that are fixed in the longitudinal direction of the flat coil or these with the individual turns of the coil using known connecting means, such as screws and nuts united.

Allgemein bekannt ist es auch dem Rohr, aus welchem eine wasser= gekühlte Induktionsspule hergestellt wird, auf der Innenseite eine größere Wandstärke als außen zu geben, um dadurch den elektrischen Wirkungsgrad zu verbessern.It is also generally known from the pipe from which a water = cooled induction coil is made to give a greater wall thickness on the inside than on the outside, thereby the to improve electrical efficiency.
Diese häufig angewendete Maßnahme brachte bei Flachspulen, wie sie für die Blockerwärraung verwendet werden, nur eine geringe Verbesserung bezüglich der Standfestigkeit.This frequently used measure resulted in flat coils, as they are used for block heating, only one little improvement in terms of stability.
Aufgabe der Erfindung ist es, eine in radialer Richtung wirkende j Spanneinrichtung vorzuschlagen, mit welcher die geraden Ab= schnitte der Windungen einer Flachspule an ihren Enden von außen mit einem Druck beaufschlagt sind und diesen Windungs= abschnitten gleichzeitig auch noch in der Hitte eine nach außen gerichtete Vorspannung gegeben wird.The object of the invention is to provide a j To propose a clamping device with which the straight Ab = sections of the turns of a flat coil are subjected to pressure from the outside at their ends and this turn = sections at the same time an outwardly directed bias is also given in the Hitte.
Zu diesem Zv/eck wird erfindungsgemäß vorgeschlagen, daß Rahmen für die gleichzeitige Aufnahme von senkrecht zu den Spulen= windungen auf deren geraden, sich parallel gegenüberliegenden Abschnitten aufliegende, isolierte Druckbalken und mittig zwischen diesen angeordnete Zugeinrichtungen vorgesehen sind.For this Zv / corner it is proposed according to the invention that the frame for the simultaneous recording of turns perpendicular to the coils = windings on their straight, parallel opposite one another Sections resting, insulated pressure beams and centrally arranged between these pulling devices are provided.
Zur Einstellung der Größe der auf die Spulenwindungen von außen einwirkenden Kräfte wird nach der Erfindung empfohlen, daß sich die Druckbalken auf zueinander im Abstand einstell= baren Traversen des Rahmens abstützen.To adjust the size of the forces acting on the coil windings from the outside, it is recommended according to the invention, that the pressure beams are supported on each other in the distance adjustable = ble traverses of the frame.
Damit gleichfalls auch die in der Mitte der» geraden Spulen= abschnitte angreifenden, nach außen gerichteten Kräfte in ihrer Stärke verändert werden können, wird erfindungsgeiaäß noch vorgeschlagen, daß die Zugoinrichtungsn aus elektrisch nicht leitenden Balken bestehen, in deran Bohrungen die an jeder Spulenwindung angebrachten mit Mutten versehenen Gewinde= bolzen aufgenommen sind und die Balken Gewindespindeln tragen, welche die Traversen des Rahmens durchdringen und durch Muttern herausschraubbar sind.This also applies to those in the middle of the »straight coils = Sections attacking, outwardly directed forces can be changed in their strength, is erfindungsgeiaäß still proposed that the Zugoinrichtungsn consist of electrically non-conductive beams, in which the holes on threaded bolts attached to each coil turn with nuts are included and the bars carry threaded spindles, which penetrate the crossbars of the frame and through nuts are unscrewed.

Selbstverständlich Iä3t sich die besprochene Spanneinrichtung nicht nur bei Flachspulen verwenden. Sie ist vielmehr bei entsprechender Ausgestaltung auch für andere Spulenformen sehr gut geeignet.Of course, the discussed clamping device works do not only use with flat coils. Rather, with an appropriate configuration, it is also suitable for other coil shapes very suitable.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß bei der an ihren Breitseiten gleichzeitig mit Druck und unter Zug vorgespannten Induktionsspule praktisch keine Schwingungen mehr auftreten und sich daher die Spule auch nicht mehr verformt. Dadurch wird die Beschädigung der Spulenisolation vermieden und ein frühzeitiger Ausfall der Induktionsspule verhindert.The advantages achieved by the invention are in particular that at the same time on their broad sides with Pressure and tension pretensioned induction coil practically no more vibrations occur and therefore the coil also no longer deformed. This avoids damage to the coil insulation and an early failure of the Induction coil prevented.
