Description

Bei dem normalen Ausstanzen der Fenster aus den Käfigmänteln der Rollenkörbe erhalten sie, sofern das Ausstanzen aus dem fertigen Rohrstück erfolgt, parallele Wände, und sie müssen, um den zylindrischen Rollen ein gutes Widerlager zu bieten, nachträglich in eine im Querschnitt trapezförmige oder seitlich gebauchte Form gebracht werden. Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung, durch die eine Umgestaltung der Stege des Mantels in einer einfachen und billigen Weise bewirkt wird.With the normal punching out of the windows from the cage shells of the roller baskets received they, if the punching takes place from the finished pipe section, parallel walls, and in order to provide a good abutment for the cylindrical rollers, they have to be inserted afterwards a trapezoidal or laterally bulged shape can be made. the Invention relates to a method and apparatus by which a redesign the ridges of the jacket is effected in a simple and inexpensive manner.

Nach dem Verfahren werden die beim Ausstanzen entstehenden Stege b des Mantels durch einen Satz angespitzter Stempel £, die der Länge der Fenster k entsprechen (Abb. ia), in eine parallele oder von außen nach innen breiter werdende Gestalt umgepreßt. Durch die etwas konkave Form, welche die Stege hierbei außen annehmen, erhöht sich zugleich ihre Knickfestigkeit. Bei Anwendung konvex zulaufender Stempel/)1 (Abb. ι unten) an Stelle der geradflächig zunehmenden Stempel p (Abb. 1 oben) erhalten die Seitenflächen der Stege eine der Form der Rollen r (strichpunktiert, Abb. 1) sich anpassende, gewölbte Form. Zum Umpressen der Stege können ein oder mehrere, zeitlich nacheinander wirkende Stempel oder auch ein Satz von gleichzeitig wirkenden Stempeln Anwendung finden.According to the process, the webs b of the jacket that are formed during the punching are pressed into a parallel shape or a shape that becomes wider from the outside inwards using a set of sharpened punches £, which correspond to the length of the window k (Fig.ia). Due to the somewhat concave shape that the webs assume on the outside, their resistance to buckling increases at the same time. When using convex punches /) 1 (Fig. Ι below) instead of the straight-surface increasing punches p (Fig. 1 above), the side surfaces of the webs are given a curved shape that adapts to the shape of the rollers r (dash-dotted line, Fig. 1) . One or more punches acting one after the other or a set of punches acting at the same time can be used for pressing around the webs.

Die Umformung der Stege in eine von außen nach innen sich verbreiternde Form oder in eine im Querschnitt rechteckige Form kann auch, wie Abb. 2 veranschaulicht, durch einen keilförmigen Hohlstempel q erfolgen, oder es kann eine Stanze (Abb. 2 und 2a) Verwendung finden, welche die Stegränder zuschneidet. The forming of the webs into a shape that widens from the outside to the inside or into a shape with a rectangular cross-section can also be done, as illustrated in Fig. 2, by means of a wedge-shaped hollow punch q , or a punch (Figs. 2 and 2a) can be used cutting the edges of the legs.

Die Stege können aber auch unmittelbar in richtiger Form aus dem fertigen Rohrstück ausgestanzt werden, wenn, wie Abb. 3 veranschaulicht, die zum Ausstanzen dienenden Stanzmesser η von vornherein im richtigen Winkel angesetzt werden. Das Ausstanzen der. Fenster kann auch· hier nacheinander oder, falls die Fenster hinreichend breit sind, um einen gleichzeitigen Angriff zweier Stanzmesser an einem Fenster zu gestatten, mittels paarweise zusammenwirkender Stanzmesser erfolgen.The webs can, however, also be punched out of the finished pipe section directly in the correct shape if, as illustrated in Fig. 3, the punching knives η used for punching are set at the correct angle from the outset. The punching out of the. The window can here also take place one after the other or, if the windows are sufficiently wide to allow two punching knives to attack a window at the same time, by means of punching knives interacting in pairs.

Unter Umständen genügt auch ein Widerlager für die Rollen lediglich oben und unten zwischen den Stegen. Dies kann beispielsweise auf die in Abb. 4" veranschaulichte höchst einfache Weise hergestellt werden, indem zur Aussparung der Stegzwischenräume k doppelkegelige oder auf der UmflächeUnder certain circumstances, an abutment is sufficient for the rollers only at the top and bottom between the webs. This can be produced, for example, in the extremely simple manner illustrated in FIG. 4 ″ by k double-conical spaces or on the peripheral surface to cut out the intermediate web spaces
