Description

Vorrichtung zur Verhinderung des Aufbäumens der Bleche bei Blechrichtmaschinen mit langen und kurzen Richtwalzen oder -rollen Die Erfindung betrifft eineVorrichtung zur Verhinderung dies: Aufbäumens der Bleche bei Blechrichtmaschinen mit langen. und kurzen Richtwa1z,en oder Richtrollen, von denen die kurzen sowohl nach dem Richtgut hin als auch parallel zu den langen Richtwalzen wie beim Patent 636 821, jedoch auf einer durch eine Längsbohrung der kurzen Walzen oder Rollen gesteckten Welle wie z. B. beim.Patent 7o8 661 verschoben werden können. Bei Blechrichtmaechinen der genannten Art kann es vorkommen, daß beim Strecken von mittleren Längszonen von Blechtafeln sich die am Einlaufende der Tafeln befindlichen. Ecken in dem freien Raum seitlich zwischen den Lagerböcken. der kurzen. Richtwalzen oder Richtrollen und dem Maschinengestell aufbäumen. Dies hat zur Folge, daß die Förderung des mittellängs gestreckten Bleches durch Anstoßen der genannten Ecken an der auf die kurze Richtwalze oder Richtrolle folgenden langen Richtwalze in der Maschine zum Stillstand kommt. während der «-eiter zurück liegende Tafelteil unter Umständen weitergefördert wird, wodurch dann die Tafel derart verheult und verbogen werden kann, daß sie unbrauchbar ist, abgesehen von den Schwierigkeiten und dem Zeitverlust, die das Entfernen der verbogenen Blechtafel zwischen den Richtwalzenreihen bereitet.Device to prevent the sheets from rearing up in sheet leveling machines with long and short straightening rolls or rolls The invention relates to a device to prevent this: Raising of the sheets in sheet leveling machines with long. and short straightening rollers, or straightening rollers, of which the short ones both after the material to be straightened towards and parallel to the long straightening rollers as in patent 636 821, however on a shaft inserted through a longitudinal bore in the short rollers or rollers such as B. in the patent 7o8 661 can be moved. With sheet metal straightening machines of the type mentioned, it can happen that when stretching central longitudinal zones of metal sheets are those at the entry end of the sheets. Corners in the free Space laterally between the bearing blocks. the short one. Straightening rolls or straightening rolls and raise the machine frame. This has the consequence that the promotion of the middle longitudinal stretched sheet by abutting the corners mentioned on the short Straightening roll or straightening roll following long straightening roll in the machine to a standstill comes. while the part of the table that is further back may be further promoted becomes, whereby then the board can be soiled and bent that it is unusable is, apart from the difficulty and loss of time involved in removing the bent sheet metal between the rows of straightening rolls.

Diese Mißständc werden durch die vorliegende Erfindung beseitigt.These inconveniences are eliminated by the present invention.

Das Neue bestellt darin, daß auf der durch die Längsbohrung der kurzen Richtwalzen oder Richtrollen gesteckten Welle. die im Falle der Anordnung eines Drehantriebs der kurzen Riclitivalzen zugleich deren Antriebswelle ist, längs federnde Wickel. z. B. in Form von Bandschrauben, aufgesteckt sind, die sich in jeder Stellung der kurzen Richtwalzen oder Richtrollen über den ganzen, zwischen den Lagerböcken der letzteren und dem Maschinengestell liegenden Raum erstrecken.What is new is that on the through the longitudinal bore of the short Straightening rollers or straightening rollers inserted shaft. which in the case of the arrangement of a Rotary drive of the short Riclitivalzen is also the drive shaft, longitudinally resilient Wrap. z. B. in the form of band screws are attached, which are in every position the short straightening rolls or straightening rolls over the whole, between the bearing blocks the latter and the machine frame extending space.

Ein Ausführungsbeispiel des Erfindungsgegenstands mit auf eine Antriebswelle gesteckten kurzen Richtivalzeii ist in der Zeichnung dargestellt, und zwar zeigt _U1. i die Vorder- und A11.2 die Seitenansicht der Blechrichtniaschine und A11. 3 die Vorder- und Seitenansicht einer Lagerstelle der Antriebswelle für die kurzen Richtwalzen mit auf die Antriebswelle aufgesteckter Bandschraube in vergrößerter Darstellung.An embodiment of the subject matter of the invention with a drive shaft inserted short Richtivalzeii is shown in the drawing, namely shows _U1. i the front and A11.2 the side view of the sheet metal straightening machine and A11. 3 the front and side views of a bearing point of the drive shaft for the short ones Straightening rollers with the strap screw attached to the drive shaft in an enlarged Depiction.

In den vom -'#,lascliinenjoc11 3 getragenen Lagern 32 sowie in den Lagerbö .ken 8 der kurzen Richtwalzen j ist deren Antriebswelle. die beim gezeichneten Ausführungsbeispiel aus zwei durch ein Kupplungsstück 20 gelenkig verbundenen Teilen i-. und ig besteht. abgestützt. Die Lager 32 machen das Heben und Senken der kurzen Richtwalzen ; und deren Lagerböcke 8 mit.In the bearings 32 carried by the - '#, lascliinenjoc11 3 as well as in the Bearing blocks .ken 8 of the short straightening rollers j is their drive shaft. the one drawn Embodiment of two parts articulated by a coupling piece 20 i-. and ig consists. supported. The bearings 32 do the raising and lowering of the short ones Straightening rolls; and their bearing blocks 8 with.

Um nun zu verhindern, daß sich heim Strecken der mittleren Längszone von Blechtafeln die in den seitlich zwischen den Lagerböcken 8 und dem Maschinengestell i befindlichen Raum gelangenden, vorderen Blechtafelecken aufbäumen. sind erfindungsgemäß auf die M"elle 14, ig längs federnde Wickel, z. B. in Form von Bandschrauben 43, auf-Cfesteckt. Diese stehen unter ihrem eigenen Federdruck einerseits am Lagerbock 8 und andererseits an den Wellenlagern 32 an und erstrecken sich in jeder Stellung des Lagerhacks 8 über den ganzen zwischen ihren lagern 8 und 32 liegenden Raum. Die M'ickel d3 sitzen mit geringem Spiel auf der Welle t4. i9 und besitzen deti ungefähren Durchin2sser der langen Richtwalzen 4.In order to prevent himself from stretching the central longitudinal zone of sheet metal in the laterally between the bearing blocks 8 and the machine frame Jack up the front sheet metal corners that come into the room. are according to the invention on the m "elle 14, ig longitudinally resilient coils, for example in the form of strap screws 43, on-C fixed. These are under their own spring pressure on the one hand on the bearing block 8 and on the other hand to the shaft bearings 32 and extend in each position of the storage hack 8 over the entire space between their stores 8 and 32. The M'ickel d3 sit with little play on the shaft t4. i9 and own deti approximate diameter of the long straightening rollers 4.
