Abstract

The invention relates to a method for stabilizing the two snap temperatures of snap elements made of thermostatic bimetal. According to said method, the mechanical steps are not interrupted by the required thermal treatment such that the embossed snap elements are pressed flat several times at a great aging temperature. The snap elements remain in the automatic production device during said process and can then be further processed in the automatic device.

Description

Verfahren zur Herstellung von SchnappscheibenMethod for producing snap disks

Die Erfindung betrifft ein Verfahren zur Stabilisierung der beiden Schnapptemperaturen von Schnappelementen aus Thermobimetall, bei dem die maschinellen Arbeitsschritte durch die Wärmebehandlung nicht unterbrochen werden.The invention relates to a method for stabilizing the two snap temperatures of snap elements made of bimetallic strip, in which the mechanical operations are not interrupted by the heat treatment.

Schnappelemente werden aus Thermobimetallband gestanzt und sie haben vorzugsweise Kreisform. Es sind aber auch andere Formen möglich und üblich: z.B. Quadrate, Rechtecke, Rhomben und Formen mit einer Zunge in der Mitte. Wenn in der folgenden Patentschrift von Schnappscheiben gesprochen wird, können alle diese Formen gemeint sein.Snap elements are stamped from Thermobimetallband and they preferably have a circular shape. However, other forms are possible and customary: e.g. Squares, rectangles, rhombuses and shapes with a tongue in the middle. When reference is made in the following specification of snap discs, all these forms may be meant.

Schnappelemente aus Thermobimetiall umfassen ein großes Anwendungsgebiet zur Regelung und zur Begrenzung von thermischen Vorgängen. Die beiden Temperaturen, bei denen sich die Wölbung der Scheiben plötzlich sprunghaft ändert, werden "untere Schnapptemperatur und obere Schnapptemperatur" genannt.Thermobimetal snap-in elements cover a wide range of applications for controlling and limiting thermal processes. The two temperatures at which the curvature of the discs suddenly changes abruptly are called "lower snap temperature and upper snap temperature".

Es ist allgemein bekannt, daß die verschieden stark geprägte Wölbung der Scheiben für die Lage dieser beTden Temperaturen maßgebend ist. Diese Wölbung wird mit unterschiedlich starker Prägung von beiden Seiten aufgebracht. Die Wölbung hat vorzugsweise die Form einer sehr flachen Kugelkalotte, es sind aber auch andere Formen möglich, z.B. die eines sehr flachen abgeschnittenen Kegelstumpfes.It is well known that the different degrees of curvature of the discs for the location of these bedenden temperatures prevail. This curvature is applied with different degrees of embossing from both sides. The curvature is preferably in the form of a very shallow spherical cap, but other shapes are possible, e.g. that of a very flat truncated truncated cone.

Die Figur 1 zeigt den Zusammenhang zwischen Temperatur und Wölbung. Auf der Abszisse ist die Temperatur aufgetragen und auf der Ordinate die Wölbung der Schnappscheiben. Beim Erreichen der oberen und der unteren Schnapptemperatur springt die Wölbung plötzlich auf die andere Seite. Die Alterungstemperatur, von der später die Rede sein wird, liegt weit über der oberen Schnapptemperatur, aber noch unterhalb der Temperatur, die zu einer Entfestigung des Bimetalles führt. Nach dem Prägen haben die Schnappscheiben noch zu wenig thermische Stabilität, das heißt, daß sich die Schnapptemperaturen mit der Zahl der Schnappbewegungen ändern. Es ist notwendig und üblich, die Schnappscheiben nach dem Prägevorgang "thermisch zu altern"; dabei setzt man sie auf die Dauer vieler Minuten bis zu einer Stunde einer hohen Temperatur aus, die über der oberen Schnapptemperatur liegt, aber noch unterhalb des Temperaturbereiches, in dem es zu einer Entfestigung des Bimetalles kommt.FIG. 1 shows the relationship between temperature and curvature. On the abscissa the temperature is plotted and on the ordinate the curvature of the domes. When the upper and lower snap temperatures are reached, the bulge suddenly jumps to the other side. The aging temperature, which will be discussed later, is well above the upper snap temperature, but still below the temperature, which leads to a softening of the bimetal. After embossing, the snap discs still have too little thermal stability, that is, the snap temperatures change with the number of snap movements. It is necessary and customary to "thermally age" the snap disks after the stamping process; It is set for a period of many minutes to one hour of a high temperature, which is above the upper snap temperature, but still below the temperature range in which it comes to a softening of the bimetal.

Die Dauer dieser Wärmebehandlung bedingt eine vorzeitige Unterbrechung des automatischen Fertigungsvorganges und es ist kaum möglich, die noch fehlenden Arbeitsgänge, das sind: Prüfung, Selektion, Freistanzen, wieder automatisch zu Ende zu führen. Es besteht daher der berechtigte Wunsch nach einer Methode der Temperaturstabilisierung, die sich durch eine extrem kurze Einwirkungsdauer in den Maschinentakt von einer bis zu zwei Sekunden einordnen läßt.The duration of this heat treatment requires a premature interruption of the automatic production process and it is hardly possible to perform the missing operations, which are: testing, selection, free dancing, again automatically to the end. There is therefore a legitimate desire for a method of temperature stabilization, which can be classified by an extremely short exposure time in the machine cycle of one to two seconds.

Die Lösung dieses Problemes ist Gegenstand der Erfindung.The solution to this problem is the subject of the invention.

Der Erfindungsgedanke besteht darin, daß man die geprägten Scheiben bei einer hohen Alterungstemperatur plan drückt. Diesen Vorgang kann man auch mehrmals wiederholen, z.B. zwei mal bis sechs mal.The idea of the invention is that the stamped disks are pressed flat at a high aging temperature. This process can also be repeated several times, e.g. two times to six times.

Bei der maschinellen Fertigung der Schnappscheiben muß man die Scheiben schrittweise von einer Arbeitsposition zur nächsten Position führen. Dafür gibt es eine Reihe von Methoden, um die fertig gestanzten Scheiben oder die Scheiben, die noch mit einem oder mit zwei Stegen mit dem Svanzstreifen verbunden sind, zyklisch weiter zu transportieren.In the mechanical production of the snap discs you must gradually guide the slices from one working position to the next position. There are a number of methods for cyclically transporting the finished die-cut discs or the discs that are still connected to one or two webs with the svanzstreifen.

Bei der nachfolgend beispielhaft beschriebenen Fertigungsmethode wurde die zuletzt genannte Transportmethode mit dem Stanzstreifen gewählt, in dem die Scheiben noch mit einem oder mit zwei schmalen Stegen hängen bleiben. Die Figur 2 zeigt eine derartige Methode.In the manufacturing method described below by way of example, the last-mentioned transport method with the stamped strip was selected, in which the discs still remain stuck with one or two narrow webs. FIG. 2 shows such a method.

Der unterteil des U-förmigen Ofens, der sich über mehrere Arbeitspositionen erstreckt, ist mit 1 bezeichnet. Der notwendige Heizkörper hat die Nummer 2. Auf der Sohle der U-Nut gleitet das gestanzte und geprägte Bimetallband 3. Aufgrund der Beheizbarkeit der Sohle der U-Nut wird das auf der Sohle aufliegende Thermobimetallband 3 rasch auf die Alterungstemperatur erhitzt, also einer Temperatur, die über der oberen Schnapptemperatur, aber unterhalb der Erweichungstemperatur des Bimetallbandes 3 liegt. In der Nut bewegt sich lotrecht die Druckleiste 4, die die gleiche Abmessung hat wie die Sohle des Ofenunterteiles. Die Leiste wird mit einem Kraftelement Nr.5 (pneumatisch, hydraulisch, über Exzenter oder magnetisch) auf die geprägten Scheiben gepreßt; so stark, daß alle geprägten Scheiben, die sich im U-Ofen befinden, plan gepresst werden. Der Pressvorgang, mit dem die Schnappelemente plan gedrückt werden, erfolgt somit bei einer Temperatur der Schnappelemente, die über der oberen Schnapptemperatur, aber unterhalb der Erweichungstemperatur der Schnappelemente liegt. Beide Vorgänge, also Erhitzen und Pressen, finden im Klemmofen 1 statt, wobei der Vorgang des" Pressens je nach der Taktzeit des Prägeautomaten weniger als eine bis eineinhalb Sekunden dauert. Anschließend folgt ein Transportzyklus, in dem der Stanzstreifen um genau eine Position weiter gezogen wird. Dieser zyklisch ablaufende Vorgang liefert nach jedem Takt eine gealterte Scheibe, ohne daß es notwendig ist, die Scheiben aus dem Automaten herauszunehmen.The lower part of the U-shaped furnace, which extends over several working positions, is denoted by 1. The necessary radiator has the number 2. On the bottom of the U-groove slides the stamped and embossed bimetal 3. Due to the heatability of the sole of the U-groove, the thermobimetal strip 3 resting on the sole is heated rapidly to the aging temperature, ie a temperature which is above the upper snap temperature, but below the softening temperature of the bimetallic strip 3. In the groove vertically moves the pressure bar 4, which has the same size as the bottom of the furnace base. The strip is pressed with a force element no.5 (pneumatic, hydraulic, eccentric or magnetic) on the embossed discs; so strong that all embossed discs, which are located in the oven, are pressed flat. The pressing process, with which the snap elements are pressed flat, thus takes place at a temperature of the snap elements, which is above the upper snap temperature, but below the softening temperature of the snap elements. Both processes, ie heating and pressing, take place in the clamping furnace 1, the process of " pressing " taking less than one to one and one-half seconds, depending on the cycle time of the automatic stamping machine, followed by a transport cycle in which the stamping strip is pulled by exactly one position This cyclical process delivers an aged disc after each cycle, without it being necessary to remove the discs from the machine.

Die Scheiben bleiben somit im Automat und die thermische Alterung wird im Automat ausgeführt, und zwar im Arbeitstakt des Automaten.The discs thus remain in the machine and the thermal aging is carried out in the machine, namely in the working cycle of the machine.

Es ist ein nützlicher Nebeneffekt, daß man im Klemmofen 1 durch das Pressen der Scheiben die schnellst mögliche Wärmeübertragung vom Ofen auf die Scheiben erhält. Das trägt zum raschen Ablauf der Arbeitsgänge bei. Die Figur 2 zeigt, daß der Ofen-U-Unterteil und die Druckleiste 4 eine zinkenförmige Verzahnung aufweist, die ineinander greifen. Diese Verzahnung dient dazu, einen so innigen Wärmeübergang vom Ofen zur Druckleiste zu bekommen, daß eine separate Heizung der Druckleiste entbehrlich wird.It is a useful side effect that in the clamping furnace 1 by pressing the discs receives the fastest possible heat transfer from the oven to the discs. This contributes to the rapid flow of operations. FIG. 2 shows that the furnace U lower part and the pressure strip 4 have a tooth-shaped toothing, which engage in one another. This gearing is used to get such an intimate heat transfer from the oven to the pressure bar that a separate heating of the pressure bar is unnecessary.

In der oben genannten Figur 2 sind die Arbeitspositonen nicht eingezeichnet, die vor und nach dem U-Klemmofen notwendig sind. In the above-mentioned Figure 2, the working positions are not shown, which are necessary before and after the U-clamping furnace.
