Abstract

Method for producing panels ribbed on one or both sides, wherein the ribbed profile is either created by rolling on the raw material of the panels, and the panels are only punched out after the rolling of the ribbed profile, or the already punched-out panels are fed in the correct position to a pair of rollers or rolling segments and the ribbed structure is formed in them in this way.

Description

Verfahren zur Herstellung ein- oder beidseitig gerippter Scheiben. Process for producing single or double ribbed discs.
Die vorliegende Erfindung betrifft ein neuartiges Verfahren zur Herstellung ein- und. beidseitig gerippter Scheiben, also Scheiben mit einem Rippenprofil auf einer oder beiden Seiten der Scheibe.The present invention relates to a novel process for the preparation of and. Both sides ribbed discs, so discs with a rib profile on one or both sides of the disc.
Solche einseitig und auch beidseitig gerippten Scheiben sind seit Jahren bekannt. Insbesondere beidseitig gerippte Scheiben, wie sie beispielsweise in der EP-Bl-426 895 beschrieben sind, haben sich als gute Losdrehsicherungen bewährt.Such unilaterally and also ribbed on both sides discs have been known for years. In particular, both sides ribbed discs, as described for example in EP-Bl-426 895, have proven to be good Losdrehsicherungen.
Von Nachteil bei diesem Stand der Technik ist das verhältnismäßig aufwendige und daher teure Fertigungsverfahren, welches bisher für diese Scheiben erforderlich war. Allgemeine Praxis in der Serienfertigung dieser Teile ist das Prägen des Rippenprofils. Bisher lässt sich nur durch Einsatz dieses Ferti- gungsVerfahrens eine optimale Rippenkontur erzielen, die für die gewünschte Sicherungsfunktion unbedingt erforderlich ist.A disadvantage of this prior art is the relatively complex and therefore expensive manufacturing process, which was previously required for these discs. Common practice in mass production of these parts is the embossing of the rib profile. So far, only by using this manufacturing process can an optimum rib contour be achieved, which is absolutely necessary for the desired safety function.
Dieser notwendige Aufwand bei der Serienfertigung gemäß dem Stand der Technik erhöht die Herstellkosten wesentlich. Ins- besondere bei Versuchsmustern und Prototypenteilen sind die Werkzeugkosten so hoch, dass sie den Anwender abschrecken. Die Werkzeugkosten für Versuchsmuster und Prototypenteile sind nämlich gemäß dem Stand der Technik nur unwesentlich niedriger als die Kosten für die Herstellung von entsprechenden Serienwerkzeugen.This necessary effort in mass production according to the prior art substantially increases the production costs. In particular, in trial samples and prototype parts, the tooling costs are so high that they deter the user. The tool costs for test samples and prototype parts are in fact only insignificant according to the prior art lower than the cost of producing appropriate series tools.
Es ist daher Aufgabe der Erfindung, ein Verfahren zur Her- Stellung ein- und beidseitig gerippter Scheiben anzugeben, welches erheblich preisgünstiger ist, und bei dem insbesondere die Kosten bei der Herstellung von Versuchs- und Prototypenteilen deutlich geringer sind.It is therefore an object of the invention to provide a method for producing one-sided and double-sided ribbed discs, which is considerably cheaper, and in which in particular the costs in the production of test and prototype parts are significantly lower.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass das Rippenprofil durch Walzen hergestellt wird. Die Kontur kann entweder vorab im Rohmaterial als auch danach an der glatten ausgestanzten Scheibe eingeprägt werden.According to the invention, this object is achieved in that the rib profile is produced by rolling. The contour can be embossed either in advance in the raw material and then on the smooth punched disc.
Besonders bevorzugt ist es dabei, wenn das Walzen des Rippenprofils auf dem Rohmaterial der Scheiben erfolgt, und die Scheiben erst nach dem Walzen des Rippenprofils ausgestanzt werden. Auf diese Weise kann mit einem einzigen Rollenpaar ein breites Spektrum an Scheibenausführungen gefertigt wer- den. Gemäß dieser vorteilhaften Ausführungsform der Erfindung lassen sich mit den gleichen Rollwerkzeugen unterschiedliche Scheibenausführungen herstellen, bei denen Innen- und Außendurchmesser beliebig variiert werden können, ohne dass es neuer Prägewerkzeuge, wie im Stand der Technik, bedarf.It is particularly preferred in this case if the rolling of the rib profile takes place on the raw material of the discs, and the discs are punched out only after the rolling of the rib profile. In this way, a wide range of disc designs can be manufactured with a single pair of rollers. According to this advantageous embodiment of the invention, different disc designs can be produced with the same rolling tools, in which inner and outer diameter can be varied as desired, without the need for new embossing tools, as in the prior art.
Besonders bevorzugt ist es, das Rippenprofil durch Prägewalzen herzustellen.It is particularly preferred to produce the rib profile by embossing rollers.
Eine besonders effiziente Herstellmethode ergibt sich vor- zugsweise dann, wenn das Walzen des Rippenprofils durch zwei synchron laufende Rollen oder Rollensegmente erfolgt . Es können Rollen (-paare) aber auch Rollensegmente zum Prägen eingesetzt werden. Vorzugsweise kann die Vorlage für das Rippenprofil vertieft oder erhaben auf den Walzrollen angebracht werden.A particularly efficient method of production preferably results when the rolling of the rib profile takes place by means of two synchronously running rollers or roller segments. Rollers (pairs) but also roll segments can be used for embossing. Preferably, the template for the rib profile can be recessed or raised on the rollers.
Erfindungsgemäß erfolgt die Fertigung der Rippscheiben durch Walzen des Profils. Dabei erfolgt das Walzen vorzugsweise durch Prägewalzen. Die Werkzeuge und Vorrichtungen für diesen erfindungsgemäßen Fertigungsprozess sind deutlich weniger aufwendig als die für den Prägeprozess des Standes der Technik erforderlichen Werkzeuge und Vorrichtungen. Beim Walzpro- zess werden nämlich bedingt durch die linienförmige Berührung zwischen Walzen und Werkstück nur verhältnismäßig geringe Kräfte erforderlich. Vorzugsweise kann dabei die Gestaltung des Rippenprofils durch zwei synchron laufende Rollen erfolgen. Die Rippenkontur kann sowohl vertieft als auch erhaben auf den Walzrollen angebracht sein. Anschließend an den WaIz- prozess erfolgt das Ausstanzen der Scheiben. Dadurch können aus dem gleichen, bereits mit den erforderlichen Rippen versehenen Material Scheiben mit beliebigem Innen- und Außendurchmesser hergestellt werden. Dies kann für die kostengüns- tige Fertigung kleiner Mengen genutzt werden. Bei großen Serien werden die Scheibenprofile mehrfach nebeneinander angeordnet, um so den Materialverbrauch zu minimieren. Eine weitere Fertigungsmöglichkeit ergibt sich, indem die Scheiben zunächst ausgestanzt werden und dann lagerichtig einem Pro- filrollenpaar zugeführt werden.According to the invention, the production of the dials by rolling the profile. The rolling is preferably carried out by embossing rollers. The tools and devices for this manufacturing process according to the invention are significantly less expensive than the tools and devices required for the stamping process of the prior art. During the rolling process, only comparatively small forces are required due to the linear contact between the rollers and the workpiece. Preferably, the design of the rib profile can be done by two synchronously running roles. The ribbed contour can be both recessed and raised mounted on the rollers. After the WaIz- process, the punching of the discs takes place. As a result, discs of any desired inner and outer diameter can be produced from the same material already provided with the required ribs. This can be used for the cost-effective production of small quantities. For large series, the disc profiles are arranged several times next to each other to minimize material consumption. Another possibility for production results from the fact that the discs are first punched out and then fed in the correct position to a profile roller pair.
Gemäß dem Stand der Technik werden bisher ausschließlich auf Prägemaschinen gefertigte Rippscheiben produziert. Erfindungsgemäß werden aufgrund der linienförmigen Berührung der Walzen erheblich geringere Kräfte benötigt. Daher können kleinere Produktionsmaschinen zum Ausstanzen verwendet werden und die Herstellkosten sind deutlich niedriger. Der erzielte Preisvorteil wird den Anwender der Teile motivieren, dieses Sicherungssystem verstärkt zu verwenden. Ein weiterer Vorteil des erfindungsgemäßen Fertigungsverfahrens ist eine gleichmäßigere Rippenkontur auf beiden Seiten der Sicherungsscheiben, sofern beidseitig gerippte Scheiben hergestellt werden sollen. Während bei geprägten, beidseitig gerippten Scheiben auf einer Seite die Rippenkontur vollkommen abgerundet ist, ist aufgrund des Prägeprozesses auf der Gegenseite eine geringe Abplattung des Rippenradius zu erkennen. Diese Abplattung kann zwar gemäß dem Stand der Technik innerhalb der geforderten Toleranzgrenzen gehalten werden. Dennoch führt dies bei der Montage zu geringen Streuungen. Bei der erfindungsgemäß gewalzten Ausführung der beiderseitig gerippten Scheiben ist das Rippenprofil auf beiden Seiten gleich gut gerundet .According to the prior art, knives produced so far exclusively on embossing machines are produced. According to the invention, considerably lower forces are required due to the linear contact of the rollers. Therefore, smaller production machines can be used for punching and the manufacturing costs are significantly lower. The achieved price advantage will motivate the user of the parts to use this security system more intensively. Another advantage of the manufacturing method according to the invention is a more uniform rib contour on both sides of the lock washers, if both sides ribbed discs to be produced. While the rib contour is completely rounded on embossed, ribbed discs on both sides, a slight flattening of the rib radius can be recognized due to the embossing process on the opposite side. Although this flattening can be kept within the required tolerance limits according to the prior art. Nevertheless, this leads to small variations in the assembly. In the present invention rolled version of the ribbed ribs on both sides of the rib profile is equally well rounded on both sides.
Besonders deutlich zeigt sich dieser Kostenvorteil bei der Herstellung von Versuchs- und Prototypenteilen.This cost advantage is particularly evident in the production of test and prototype parts.
Mit dem erfindungsgemäßen Herstellungsverfahren kann mit ei- nem einzigen Rollenpaar ein breites Spektrum an Scheibenausführungen gefertigt werden. Mit den gleichen Rollwerkzeugen können unterschiedliche Scheibenausführungen erzeugt werden, wobei Innen- und Außendurchmesser der Scheiben beliebig variiert werden können. With the production method according to the invention, a wide range of disc designs can be manufactured with a single pair of rollers. With the same rolling tools different disc designs can be produced, the inner and outer diameter of the discs can be varied as desired.
