Description

Gewindewalzmaschine zum Kaltwalzen, vorzugsweise von feinem Metallgewinde, mit mehreren Gewindewalzen Bei bekannten Gewindewalzmaschinen mit mehreren Gewindewalzen, bei denen das Walzenauf Fertigmaß durch den letzten Gewindegang kegelförmiger Walzen vorgenommen wird, hat der letzte Gewindegang den sehr hohen Walzdruck ,auszuhalten, der häufig Ursache für das Abplatzen des Gewindeganges war.Thread rolling machine for cold rolling, preferably of fine metal threads, with several thread rollers In known thread rolling machines with several thread rollers, in which the rolling to the finished dimension through the last thread turn of conical rollers is made, the last thread turn has to withstand the very high rolling pressure, which was often the cause of the thread chipping.

Die vorliegende Erfindung vermeidet diesen Übelstand, indem Gewindewalzen Verwendung finden, die mehrere Gewindegänge zum Walzen des Gewindes auf das Fertigmaß besitzen, und die sich nach beiden Seiten hin kegelförmig verjüngen. Die Gewindewalzen sind z. B. doppelkonusartig mit zylindrischem Zwischenstück ausgebildet, oder sie steigen stufenförmig oder ballig von der einen Seite bis auf das Fertigmaß an und fallen dann gegen das Ende in gleicher Weise wieder ab. Beim Gewindewalzen mit derartigen Walzen steigt der Walzdruck allmählich an und sinkt auch allmählich ab, ohne daß überbeanspruchungen auftreten können. Ferner bewirken die Gewindegänge der Walzen ein Glätten und Kalibrieren auf genauestes Maß des Gewindes.The present invention avoids this drawback by providing thread rolling Use the multiple thread turns for rolling the thread to the finished size have, and which taper conically on both sides. The thread rollers are z. B. double cone-like with a cylindrical intermediate piece, or they rise step-like or convex from one side to the finished size and then fall off again in the same way towards the end. When thread rolling with such Rolling, the rolling pressure increases gradually and also decreases gradually without that overuse can occur. Furthermore, the threads of the rollers cause smoothing and calibrating to the most precise dimension of the thread.

Die Erfindung sei an Hand der Zeichnung, die ein Ausführungsbeispiel darstellt, näher erläutert.The invention is based on the drawing, which shows an embodiment represents, explained in more detail.

Abb. i zeigt schematisch drei Walzen einer Gewindewalzmaschine in Ansicht, Abb. z den Schnitt durch eine Walze, die gemäß der Erfindung nach beiden Seiten hin kegelförmig verjüngt ist: Zwischen denkegelförmigen Teilen a, a' befindet sich der zylindrische Teil b. Das Gewinde über die Teile a, b und a' der Walze ist durchweg mit vollem Profil ausgebildet.Fig. I shows a schematic view of three rolls of a thread rolling machine, Fig. Z shows the section through a roll which, according to the invention, is tapered conically on both sides: the cylindrical part b is located between cone-shaped parts a, a '. The thread over the parts a, b and a 'of the roller is designed with a full profile throughout.
