Abstract
Description
Verfahren und Vorrichtung zum Antreiben, Biegen wnd/oder Führen vonMethod and device for driving, bending and / or guiding
Metallband, insbesondere bei der Herstellung von Schraubennahtrohren Die Erfindung betrifft ein Verfahren gemäß dem Oberbegriff des Anspruches 1 und eine Vorrichtung zur Durchführung des Verfahrens.Metal tape, especially in the manufacture of screw sutures The invention relates to a method according to the preamble of claim 1 and a device for carrying out the method.
Bei der bisher bekannten Herstellung von Schraubennahtrohren wird das Band vor Einlauf in eine Dreiwalzen-Biegenaschine durch einen Bandtreiber angetrieben. Die Walzen der Biegemaschine sind in schmale Einzelrollen gegliedert und in der Regel winkelverstellbar.In the previously known production of screw sutures the belt is driven by a belt driver before entering a three-roll bending machine. The rolls of the bending machine are divided into narrow individual rolls and in the Usually angle adjustable.
Bei dieser Herstellung nissen bei der Verarbeitung relativ dAnner Bänder diese auf der Strecke zwischen Antrieb und Einformung in vertikaler Richtung abgestützt werden damit die eingeleiteten Schubkräfte die Bänder nicht ausknicken und es ist außerdem insbesonder ein relativ großer maschineller Aufwand erforderlich für die separat gestalteten Anlagenteile: Biegesystem, Bandtreiber und Bandführungssystem.In this production, the processing nesses are relatively thin Straps these on the path between the drive and the molding in the vertical direction The shear forces introduced are supported so that the ligaments do not buckle and it is also necessary in particular a relatively large amount of machinery for the separately designed system parts: bending system, belt driver and belt guide system.
Der Erfindung liegt von daher die Aufgabe zugrunde ein Verfahren und eine Vorrichtung zur Einformung von Schraubennahtrohren zu schaffen, wobei insbesondere von einer vertikalen Abstützung des Bandes abgesehen werden kann und eine einwandfreie Einformung des Bandes bei möglichst geringem Mbschinen- und Arbeitsaufwand erreicht wird.The invention is therefore based on the object of a method and to create a device for forming screw sutures, in particular a vertical support of the belt can be dispensed with and a flawless one Formation of the belt achieved with the least possible amount of machinery and work will.
Gemäß der Erfindung wird diese Aufgabe bei einer Einrichtung der eingangs bezeichneten Gattung durch das in den Kennzeichen der Ansprüche 1 und 2 Erfaßte gelöst.According to the invention, this object is achieved in a device of the initially mentioned designated genus by what is included in the characteristics of claims 1 and 2 solved.
Die Vorteile der Erfindung bestehen insbesondere darin, daß bei geringe Aiod die vertikale Pührung des Bandes vor der Biegemaschine entfällt, eine Nachjustierung der WÜkaleinstellung der Antriebswalzen während des Betriebes stufenlos ermöglicht und die Bandeinlaufstecke durch die Xombination Biegesystee/Bandtreiber verkürzt wird.The advantages of the invention are in particular that at low There is no need for vertical guidance of the strip in front of the bending machine, readjustment enables the WÜkal setting of the drive rollers to be infinitely variable during operation and the belt infeed section is shortened by the combination of bending system / belt driver will.
Nachfolgend wird die Erfindung anhand eines schematisch dargestellten Ausführungsbeispieles erläutert, Es zeigt Fig, 1 die Draufsicht der Oberwalze der kombinierten Biege-Antriebsvorrichtung Fig. 2 eine Ansicht in Richtung des Pfeiles X gemäß Fig. 1, wobei demgegenüber die Laufringe in senkrechter Stellung zur Wellenachse verschwenkt dargestellt sind Fig. 3 eine Teildraufsicht im Schnitt gemäß Fig. 1 Fig. 4 eine Teildraufsicht im Schnitt gemaß Fig. 1, jedoch in der Situation nach Weiterdrehung der Welle um 90° gegenüber der Darstellung in Fig. 1 und 3.The invention is illustrated schematically below with the aid of a Embodiment explained, It shows Fig, 1 is a plan view of the top roller of the combined bending drive device Fig. 2 is a view in the direction of the arrow X according to FIG. 1, in contrast to which the races are in a perpendicular position to the shaft axis FIG. 3 is a partial plan view in section according to FIG. 1 Fig. 4 is a partial plan view in section according to FIG. 1, but in the situation after Further rotation of the shaft by 90 ° compared to the illustration in FIGS. 1 and 3.
Das Band 1 wird in Einffhrungsrichtung V dem aus einer angetriebenen Oberwalze und zwei antriebslosen, nicht dargestellten Uhterwalzen bestehenden Dreiwalzen-Biegesystem zugeführt dort gebogen und mit einer nicht dargestellten Schweißeinrichtung zun Schraubennahtrohr verschweißt (Fig. 1).The belt 1 is driven in the insertion direction V from a Top roll and two non-powered Uhter rolls, not shown, existing three-roll bending system fed there bent and with a welding device, not shown, zu Welded screw suture tube (Fig. 1).
Die Oberwalze besteht im wesentlichen aus einer fliegend gelagerten Welle 2 mit kardanisch gelagerten Laufringen 3, die durch eine Führungsvorrichtung 4 parallel gefflhrt und sowohl im Stillstand als auch während des Betriebes stufenlos verstellt werden können, so daß die Drehrichtung der Laufring 3 etwa parallel zu der Einf(fligsrichtung V des Bandes 1 verläuft, Die nicht dargestellten schmalen Einzelrollen der beiden Unterwalzen der Dreiwalzen-Biegemaschine werden ebenfalls entsprechend der Einführungstichtung V des Bandes 1 eingestellt, Für die Funktion der Laufringverstellunig an der Oberwalze der Dreiwalzen-Biegemascine ergibt sich aus den Fig. 1 bis 4. daß auf der in den Lagern 5, 6 fliegend gelagerten angetriebenen Welle 2 über zwei diametral angeordnete Drehzapfen 7, Zwischenringe 8 gelagert sind, Am Außenumfang der ru die gemeinsame Achse der Drehzapfen 7 schwenkbaren Zwischenringe 8 sind, - um 900 zu den am Innenumfang angeordneten Drehzapfen 7 versetzt, - diametral zwei Drehzapfen 9 angeordnet, um deren gemeinsame Achse sich die Laufringe 3 bewegen können.The top roller essentially consists of a cantilevered one Shaft 2 with gimbal bearing races 3, which are guided by a guide device 4 run in parallel and infinitely variable both during standstill and during operation can be adjusted so that the direction of rotation of the race 3 is approximately parallel to the insertion direction V of the tape 1 runs, the not shown narrow Individual rolls of the two lower rolls of the three-roll bending machine are also used set according to the insertion direction V of the tape 1, for the function the Laufringverstellunig on the top roll of the three-roll bending machine results from Figs. 1 to 4. that on the overhung in the bearings 5, 6 driven Shaft 2 are mounted via two diametrically arranged trunnions 7, intermediate rings 8, On the outer circumference of the ru the common axis of the pivot pin 7 pivotable intermediate rings 8 are, - offset by 900 to the pivot pins 7 arranged on the inner circumference, - diametrically two pivot pins 9 are arranged, about the common axis of which the races 3 move can.
Die Führungsvorrichtung 4 besteht im wesentlichen aus sich in Führungsnuten lo der Laufringe 3 führenden und abstützenden, halbschalenartig ausgebildeten Führungssegmenten 11, mit denen über Verbindungsstangen 12, 13, 14 mittels eines Stellantriebes 15 auch während des Betriebes stufenlos die Laufringe 3 in die gewünschte Einführungsrichtung V verstellt werden können. Die Verbindungsstange 13 ist dabei an dem Lager 6 und an einer durch die Welle 2 geführten Stütze 16 gehalten. Bei Drehung der Welle 2 ergibt sich, daß die Laufringe 3 durch die Führungsvorrichtung 4 in der eingestellten Einführungsrichtung V bleiben. Durch die kardanische Lagerung über die Drehzapfen 7 9 fuhren dagegen die Zwischenringe 8 eine Tauselbewegung aus, wobei zwei Taumelstellungen in den Fig, 1 und 3 bzw.The guide device 4 essentially consists of guide grooves lo the races 3 leading and supporting, half-shell-like guide segments 11, with which via connecting rods 12, 13, 14 by means of an actuator 15 Even during operation, the races 3 can be steplessly adjusted in the desired direction of insertion V can be adjusted. The connecting rod 13 is on the bearing 6 and held on a support 16 guided through the shaft 2. When the shaft rotates 2 it results that the races 3 by the guide device 4 in the set Insertion direction V remain. Thanks to the cardanic bearing on the pivot pin 7 9, however, the intermediate rings 8 perform a swiveling motion, with two tumbling positions in Figures 1 and 3 or
