Description
Bekannt ist, daß die Richtwalzen an Blechrichtmaschinen mittels Stützrollen abgestützt werden, wobei jedoch die Stützrollen keinen besonderen Antrieb haben, sondern durch Reibung, die durch den Richtwalzendruck zwischen Richtwalze und Stützrollen entsteht, mitgenommen werden sollen.It is known that the straightening rollers are supported on sheet leveling machines by means of support rollers are, however, the support rollers have no special drive, but by Friction caused by the pressure between the straightening roll and the support rolls, should be taken.
Durch das Fehlen jeglichen Antriebes kommt es öfters vor, daß die eine oder andere Stützrolle stehenbleibt und dadurch Beschädigungen der Rieht- wie Stützrollen, hervorgerufen werden. Beim Richten, von blanken Qualitätsblechen kommt noch hinzu, daß sich diese Beschädigungen auf die Bleche übertragen, die dann nicht mehr verwendbar sind. Bei Richtmaschinen mit awei- oder mehrfacher Abstützung ist die Gefahr des Stehenbleibens einzelner Stützrollen noch viel größer.Due to the lack of any drive, it often happens that one or other support roller stops and this causes damage to the straightening and support rollers, be evoked. When straightening bare quality sheets, there is also that this damage is transferred to the metal sheets, which can then no longer be used are. There is a risk of straightening machines with two or more supports the stopping of individual support rollers is much greater.
Durch nachstellend beschriebene Erfindung werden diese Mißstände restlos beseitigt, da ein Stehenbleiben der Stützrollen und somit eine Beschädigung der Rieht- und Stützrollen sowie des Richtgutes vollständig ausgeschlossen ist.Through the inventions described in the following, these abuses are completely eliminated, because the support rollers come to a standstill and thus damage the rectifier and Support rollers as well as the target material is completely excluded.
Abb. ι zeigt einen Längsquerschnitt einer Blechrichtmaschine mit Antrieb der Stützrollen, Fig. Ι shows a longitudinal cross-section of a sheet leveler with drive of the support rollers,
Abb. 2 eine Ansicht von Abb. 1. Eine auf Richtwalzen 1 sitzende verzahnte Hülse 2 treibt ein Stirnrad 3, welches Ritzel 4, Welle S und Kettenrad 6 in Bewegung setzt, wobei die Umlaufgeschwindigkeiten Richtwalze 1 und Kettenrad 6 genau übereinstimmen. Die Stützrollen 10 tragen auf dem verlängerten Lagerzapfen Kettenräder ß. Eine Gelenkkette-7, die durch Kettenrad 6 angetrieben wird, läuft über Führungsrollen 16, 19 sowie Spannrolle 13 über Führungsschiene 9, welche am Lagerkörper 11 so befestigt ist, daß die Kette beim Gleiten über diese Führungsschiene die Kettenräder 8 in Bewegung setzt. Da die Stützrollen während des Richtens gehoben bzw. gesenkt werden, sind zum Ausgleich exzentrisch verstellbare Führungsrollen 19 sowie eine von sich selbst einstellbare Spannrolle 13 angeordnet.Fig. 2 is a view of Fig. 1. A toothed sleeve 2 seated on straightening rollers 1 drives a spur gear 3, which sets the pinion 4, shaft S and sprocket 6 in motion, the rotating speeds of straightening roll 1 and sprocket 6 exactly matching. The support rollers 10 carry chain wheels ß on the extended journal. An articulated chain 7, which is driven by chain wheel 6, runs over guide rollers 16, 19 and tension roller 13 over guide rail 9, which is attached to bearing body 11 so that the chain sets sprockets 8 in motion when sliding over this guide rail. Since the support rollers are raised or lowered during straightening, eccentrically adjustable guide rollers 19 and a self-adjustable tensioning roller 13 are arranged for compensation.
Bei zwei oder mehr Abstützungen erfolgt der Antrieb von einer Seite, und sind die nebeneinanderliegenden Stützrollen ι ο mittels Kuppelzapfen 17 und Kupplungshülsen 18 gekuppelt. If there are two or more supports, the drive is from one side, and they are Adjacent support rollers ι ο coupled by means of coupling pins 17 and coupling sleeves 18.
An die Stelle des Kettenantriebes können auch andere gleichwirkende Antriebsmittel, wie Kegelräder o. dgl., treten.Instead of the chain drive, other drive means with the same effect can also be used, like bevel gears or the like.
