Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand der Erfindung ist ein Verfahren zum Richten von Universaleisen und Blechstreifen, das darin besteht, daß die Werkstücke zunächst eine einseitige Biegung erfahren, worauf sie wieder in ihre gestreckte Form zurückgebracht werden.The invention relates to a method for straightening universal iron and sheet metal strips, that consists in the fact that the workpieces are first bent on one side, whereupon they are returned to their stretched shape.
Das neue Verfahren kann in der Weise ausgeführt werden, daß die von Unebenheiten zu befreienden Streifen zunächst auf einerThe new method can be carried out in such a way that that of bumps strip to be freed initially on one
ίο bekannten Biegemaschine so weit gekrümmt werden, daß alle Beulen o. dgl. verschwinden, worauf die Streifen auf einer zweiten, beispielsweise umgekehrt eingebauten Biegemaschine annähernd wieder in ihre gerade Form gebracht werden. Um die gestreckte Form genau wieder herzustellen, können die Streifen noch durch eine Blechrichtmaschine von bekannter Bauart mit mehreren Ober- und Unterwalzen hindurchgeführt werden.ίο known bending machine so far curved be that all bumps o. The like. Disappear, whereupon the stripes on a second, for example reversed built-in bending machine can be brought almost back into its straight shape. To the stretched one The strips can still be reproduced exactly with a sheet leveler of known design with several upper and lower rollers are passed through.
Die zwei oder drei vorerwähnten Maschinen werden dicht hintereinander derartig angeordnet, daß die Streifen aus der einen Biegewalze in die andere und aus dieser in die Blechrichtmaschine gelangen. Der Antrieb der einzelnen Maschinen wird dabei, um ein Zerren des Materials in seiner Längsrichtung zu verhüten, mit unstarren Maschinenteilen, z. B. Riemen oder Schleif kupplungen ο. dgl., versehen, damit die Umfangsgeschwindigkeiten der verschiedenen Walzen sich selbsttätig regeln können.The two or three machines mentioned above are arranged close to one another in such a way that that the strips get from one bending roller into the other and from this into the sheet leveler. The drive the individual machines are doing this to tugging the material in its longitudinal direction to prevent, with non-rigid machine parts, z. B. belts or slip clutches ο. like., provided so that the peripheral speeds of the various rollers are automatic can regulate.
Auf der beiliegenden Zeichnung sind zwei Ausführungsbeispiele von Einrichtungen zur Ausübung des neuen Verfahrens schematisch dargestellt.On the accompanying drawing are two embodiments of devices for Exercise of the new process shown schematically.
Gemäß Fig. 1 wird der zu ebnende Streifen α in der Biegemaschine b gekrümmt und dann in der umgekehrt angeordneten Biegemaschine c annähernd oder völlig wieder in seine ursprüngliche gestreckte Form zurückgebogen. Die genaue gestreckte Form des Streifens wird durch die Blechrichtmaschine d, deren Bauart bekannt ist, wieder hergestellt.According to FIG. 1, the strip α to be leveled is curved in the bending machine b and then bent back approximately or completely into its original stretched shape in the bending machine c, which is arranged upside down. The exact elongated shape of the strip is restored by the sheet leveling machine d, the type of which is known.
Bei geeigneter Leitung des Streifens α kann auch das Rückbiegen desselben dadurch geschehen, daß der Streifen α aus der Biegemaschine b unmittelbar in die Blechrichtmaschine d eingeführt wird, wobei dann die Biegemaschine c entbehrlich wird. Diese Anordnung ist in Fig. 2 der Zeichnung dargestellt. With suitable guidance of the strip α, it can also be bent back by inserting the strip α from the bending machine b directly into the sheet straightening machine d , the bending machine c then being unnecessary. This arrangement is shown in Figure 2 of the drawing.
