Description

Die Erfindung betrifft eine Vorrichtung zum Runden von geschlitzten Hülsen. Derartige Hülsen sind z. B. unter dem Namen Spannstifte bekannt und werden als Paßstifte verwendet. Paßstifte müssen aber unbedingt rund und maßhaltig sein, wenn sie ihre Aufgabe erfüllen sollen. Es ist daher nötig, die aus Bändern zusammengebogenen Hülsen, die nur selten rund ausfallen, einer besonderen Nachbehandlung zu unterziehen, welche der Hülse die verlangte genaue Rundung gibt. Erfindungsgemäß werden hierzu-eine feste zylindrische Wand und eine koaxial dazu sich drehende Walze mit einem um den Hülsendurchmesser kleineren Radius benutzt und zwischen beide die zu rundenden Hülsen mittels eines Trichters parallel zur Walzenachse eingebracht. Walze und zylindrische Wand werden vorteilhaft mit leichten Rillen versehen.The invention relates to a device for rounding slotted Pods. Such sleeves are z. B. known under the name of dowel pins and are used as dowel pins. Dowel pins must be round and true to size, when they are supposed to do their job. It is therefore necessary to use the ribbons that are bent together To subject sleeves that are rarely round to a special follow-up treatment, which gives the sleeve the exact rounding required. According to the invention for this purpose a solid cylindrical wall and a coaxially rotating roller with a to the Sleeve diameter smaller radius used and between both the sleeves to be rounded introduced by means of a funnel parallel to the roller axis. Roller and cylindrical Wall are advantageously provided with slight grooves.

Die Zeichnung gibt eine Vorrichtung gemäß der Erfindung beispielsweise wieder. Die Abb. i zeigt eine Hülse in der unrunden Form, wie sie beim Zusammenwalzen eines Metallbandes meistens entsteht. Abb. 2 ist eine Vorrichtung, in welcher diese Hülse ihre genaue gleichmäßige Rundung erhält. Darin ist i der Trichter, in welchen die unrunden Hülsen eingeworfen werden, 2 eine Walze, die an ihrem Umfange leicht geriffelt ist und in bekannter, hier nicht dargestellter Weise im Uhrzeigersinne angetrieben wird, 3 eine zum Walzenumfang parallele, zylindrische Gegenplatte. Nach erfolgter Rundung fallen die Hülsen in einen Behälter 4.The drawing gives an apparatus according to the invention, for example again. Fig. I shows a sleeve in the non-round shape, as it is when rolled together a metal band usually arises. Fig. 2 is a device in which this Sleeve receives its exact uniform rounding. In it i is the funnel in which the non-round pods are thrown in, 2 a roller, which is easy on its circumference is fluted and clockwise in a known manner, not shown here is driven, 3 a parallel to the roller circumference, cylindrical counter-plate. To Once rounded, the sleeves fall into a container 4.
