Description
Verfahren zur Herstellung von Grundringen für Vollgummireifen mit unterschnittenen flachen Nuten. Es ist bekannt, zur Anbringung von Vollgummireifen Grundringe aus Eisen oder Stahl mit unterschnittenen flachen Nuten zu verwenden, in die der Gummi eingreift, um auf diese Weise unverrückbar fest zu sitzen. Das Profil eines solchen Grundringes ist in der Zeichnung durch Abh. i wiedergegeben. Bisher wurden die unterschnittenenNuten auf der Drehbank erzeugt. Es ist auch iricht angängig,; wie dies an sich bekannt, die Nuten zunächst rechtwinklig zu walzen und ihre unterschnittene Form dadurch zu erreichen, daß angewalzte Rippen dusch schräge Walzflächen nach innen umgelegt werden. Die flache Form der Nuten und die Notwendigkeit, die Form des Grundkörpers mit den breiten Stegen zwischen den Nuten beizubehalten, läßt diese Art der Herstellung nicht zu.Process for the production of base rings for solid rubber tires with undercut shallow grooves. It is known to attach solid rubber tires To use base rings made of iron or steel with undercut flat grooves, into which the rubber engages in order to be immovably tight. That The profile of such a base ring is shown in the drawing by Dep. I. Previously, the undercut grooves were made on the lathe. It is also wrong accessible ,; As is known per se, the grooves must first be rolled at right angles and to achieve their undercut shape by rolling ribs at an angle Rolling surfaces are turned inwards. The flat shape of the grooves and the need to to maintain the shape of the base body with the wide webs between the grooves, does not allow this type of production.
Der Erfindung gemäß werden die unterschnittenen Nuten zwar auch durch Walzen erzeugt, indem die Nuten zunächst rechtwinklig gewalzt werden; die Überführung der Nuten in die unterschnittene Form erfogt aber dadurch, daß die Kanten der rechtwinkligen Nuten etwas erhöht angewalzt und dann niedergewalzt werden. Auf diese Weise ergeben sich die flachen unterschnittenen Nuten, ohne daß der Grundkörper irgendwie geändert würde. Durch diese Art der Herstellung werden die Grundringe für Vollgummireifen ganz erheblich verbilligt, ohne daß sie an ihrer Wirksamkeit Einbuße erlitten.According to the invention, the undercut grooves are also through Rolling generated by first rolling the grooves at right angles; the overpass of the grooves in the undercut shape, however, is achieved by the fact that the edges of the right-angled Grooves are rolled slightly increased and then rolled down. In this way surrendered the shallow undercut grooves without the main body being changed in any way would. This type of production makes the base rings for solid rubber tires considerably cheaper, without any loss of effectiveness.
In Abb. a ist beispielsweise ein Profil des Grundringes vor dem. Niederwalzen in ausgezogenen Linien dargestellt, während punktiert die Form, nach denn Niederwalzen gegeben ist, die also der Abb. i entspricht. Es wird zunächst ein Starbt mit diesem Profil erzeugt, aus dem dann der Ring gebildet wird.In Fig. A, for example, a profile of the base ring is in front of the. Rolling down shown in solid lines, while dotted the shape, after being rolled down is given, which corresponds to Fig. i. There will be one dies with this first Profile generated from which the ring is then formed.
Zuweilen sind diese Grundringe an ihren zylindrischen Flächen mit feinen Längsriefen versehen, die ebenfalls, bisher eingedreht wurden. Der Erfindung gemäß sollen auch diese Längsriefen von vornherein mit eingewalzt werden. Das geschieht am vorteilhaftesten in der Weise, daß beim Einwalzen der rechteckigen Nuten nur die Bodenflächen der Nuten, nicht aber auch schon die Stegflächen mit Riefen versehen werden. Diese erhalten ihre Riefen dann nachträglich gleichzeitig mit dem Niederwalzen der Stege beim folgenden Walzenstich.Sometimes these base rings are on their cylindrical surfaces with fine longitudinal grooves, which were also previously screwed in. The invention accordingly, these longitudinal grooves should also be rolled in from the outset. This happens most advantageous in such a way that when rolling in the rectangular grooves only the bottom surfaces of the grooves, but not also the web surfaces, are provided with grooves will. These then subsequently receive their grooves at the same time as the rolling down the webs in the following roller pass.
