Description

Vorrichtung zur Ausübung der Hin- und Herbiegeprüfung an Drähten und Blechen Zusatz zum Patent 676 995 Nach dem Hauptpatent wird die einwandfreie Hin- und Herbiegeprüfung an Drähten und Blechen dadurch erreicht, daß die Biegerolle während des Biegevorganges parallel zur Oberkante der Biegebacken geführt wird. An dieser Biegevorrichtung wird der eine Arm eines zweiarmigen Winkelhebels durch die Biegerolle heruntergedrückt, nachdem diese von der Probe abgerollt ist. Dadurch wird der andere Hebelarm und die Probe auge hoben, so daß die Biegerolle beim Rückgang unter die Probe greift und sie zurückbiegt.Device for performing the back and forth bending test on wires and Sheet metal Addition to patent 676 995 According to the main patent, the flawless rear and bending test on wires and sheets achieved in that the bending roller is guided during the bending process parallel to the upper edge of the bending jaw. On this bending device, one arm of a two-armed angle lever is pushed through the bending roller is pressed down after it has unrolled from the specimen. Through this the other lever arm and the sample is lifted eye, so that the bending roller when falling reaches under the sample and bends it back.

Es hat sich nun gezeigt, daß die Anordnung des Winkelhebels einen etwas umständlichten Bewegungsmechanismus ergibt und daß bessere Maßnahmen möglich sind. It has now been shown that the arrangement of the angle lever a somewhat cumbersome movement mechanism and that better measures are possible are.

Erfindungsgemäß werden daher zu diesem Zweck an Stelle einer Biegerolle zwei Biegerollen zum Hin- und Herbiegen der Probe angeordnet, die zwangsläufig miteinander verbunden sind und die Probe auf zwei einander gegenüberliegenden Seiten umfassen, so daß das Zurückbiegen der von der einen Rolle umgebogenen Probe durch die am Biegevorgang nicht beteiligt gewesene andere Rolle bewirlçt wird. An Hand des in Abb. I dargestellten Ausführungsbeispiels wird die Prüfungsvorrichtung gemäß der Erfindung und die Wirkungsweise näher erläutert. According to the invention therefore instead of a bending roller for this purpose two bending rollers arranged to bend the sample back and forth, which inevitably interrelate are connected and encompass the sample on two opposite sides, so that the bending back of the sample bent from one roller by the bending process other role that was not involved is carried out. On the basis of the one shown in Fig. I. Embodiment is the testing device according to the invention and the mode of operation explained in more detail.

In Abb. I sind 3 die beiden Spannbacken, deren abgerundete Kanten durch die Walzen 3' gebildet sind. Die Biegerollen 1 und 2 sind starr miteinander verbunden und werden in der durch einen Pfeil angedeuteten Richtung geradlinig hin und her gerollt. In Fig. I 3 are the two clamping jaws, their rounded edges are formed by the rollers 3 '. The bending rollers 1 and 2 are rigid with each other connected and are rectilinear in the direction indicated by an arrow and rolled here.

Hierbei wird die zwischen den Backen 3 eingespannte Probe 4 zunächst nach links um die eine der beiden abgerundeten Kanten 3' der Spannbacken in die mit 5 bezeichnete Lage gebogen. Hierauf wird die Probe in die Lage 4 zurückgeführt und wieder geradegerichtet und dann anschlieaend nach rechts in die Lage 6 gebracht. Dieses Spiel wiederholt sich bis zum Bruch der Probe.Here, the sample 4 clamped between the jaws 3 is initially to the left around one of the two rounded edges 3 'of the clamping jaws in the bent position marked 5. The sample is then returned to position 4 and straightened it again and then brought it to position 6 to the right. This game is repeated until the sample breaks.

Durch die vorgeschriebene Anordnung wird in einfacher Weise erreicht, daß die Probe wie beim Hauptpatent ohne Abfederung um die Biegekanten gelegt wird und daß sie dann ohne zusätzliche umständliche Kippvorrichtung wieder nach der anderen Biege seite umgelegt werden kann. The prescribed arrangement achieves in a simple manner that the sample is placed around the bending edges without cushioning, as in the main patent and that they are then back after the other without an additional cumbersome tilting device Bending side can be turned over.

Für das Wesen der Erfindung ist es belanglos. ob die Oberkante der Biegeebene horizontal entsprechend der Abb. 1 oder in Kreisform entsprechend der Abb. 2 ausgebildet ist. It is irrelevant to the essence of the invention. whether the top of the Bending plane horizontally according to Fig. 1 or in a circular shape according to Fig. 2 is formed.
