Abstract

The installation is used to prepare pipe and rod material by de-scaling and straightening it, so that it becomes suitable for further machining in automatic lathes, etc. The installation consists of two groups of shafts on which rollers are mounted at a certain distance from one another. The first group of shafts is fixed while the other group can be moved parallel with respect to the first one. The rollers on one group are axially displaced from those on the other group. At least one of the group of rollers can be driven. The material which is to be straightened and de-scaled is driven round at a speed which differs from the speed of rotation of the rollers, in order to exert a torque on the material which will twist it, up to its limit of elasticity.

Description

Schälmaschinen-Anlage zum Richten und Schälen stangenförmigen Gutes (Zusatz zu Patent ...... (P 24 41 989.4) Im Hauptpatent wurde eine Schälmaschinen-Anlage zum Bearb2iten stangenförmigen Gutes, wie Rohre, Stangen, Wellen od. dgl., durch Richten und Schälen, gegebenenfalls auch Anfasen, bevor es in Automaten weiterverarbeitet wird, beschrieben, wobei vor und/oder hinter der Schälmaschine parallel zum Zufuhr- und Abfuhrgang je zwei Gruppen von Wellen mit auf ihnen festgelegten, voneinander beabstandeten Walzen angeordnet sind, von denen die eine Gruppe ortsfest gelagert und die andere Gruppe parallel zur ersten zeitlich steuerbar und einstellbar verschwenkbar ist, die Walzen der einen Gruppe gegenüber den Walzen der anderen Gruppe axial versetzt sind, und mindestens eine der Walzengruppen antreibbar ist. Peeling machine system for straightening and peeling rod-shaped goods (Addition to patent ...... (P 24 41 989.4) The main patent included a peeling machine system for processing rod-shaped goods such as pipes, rods, shafts or the like Straightening and peeling, if necessary also chamfering, before it is further processed in machines is described, with in front of and / or behind the peeling machine parallel to the feed and discharge passage each two groups of waves with fixed on them, from each other spaced rollers are arranged, of which a group is fixedly mounted and the other group can be swiveled in a timed and adjustable manner parallel to the first is, the rollers of one group are axially offset from the rollers of the other group are, and at least one of the roller groups can be driven.

Soweit das zu richtende und zu schälende Gut einen verhältnismäßig großen Querschnitt aufweist, hat sich die vorstehend gekennzeichnete Schälmaschine bewährt. Es zeigt sich jedoch, ist der Querschnitt des zu richtenden und zu schälenden Gutes verhältnismäßig gering, wie dies beispielsweise bei Draht der Fall ist, daß das geschälte Gut eine Krümmung mit verhältnismäßig großem Krümmungsradius aufweist, wobei sich die Krümmung im Regelfall in einer Ebene erstreckt. Das geschälte Gut weist also einen Säbelbogen auf. Ein solcher Säbelbogen kann bei der Weiterverarbeitung des Gutes in nachfolgenden Operationen, z.s. beim Transport in Rollgängen, stören, so daß man ge#wungen1 ist, das Gut für den bzw. die dem Schälen folgenden Arbeitsgänge durch einen gesonderten Richtvorgang wieder maschinen gerecht zu gestalten. Dieser Säbelbogen kann insbesondere dann verhältnismäßig stark ausgebildet sein, wenn die Zerspanungsleistung beim Schälen verhältnismäßig groß ist, sei es durch eine verhältnismäßig große Spantiefe, sei es durch einen verhältnismäßig großen Vorschub pro Umdrehung des Schälkopfes.As far as the goods to be straightened and peeled are proportionate has a large cross-section, the peeling machine characterized above has proven. It turns out, however, is the cross-section of what is to be straightened and peeled Relatively little good, as is the case, for example, with wire that the peeled product has a curvature with a relatively large radius of curvature, the curvature generally extending in one plane. The peeled good thus has a saber bow. Such a saber bow can be used in further processing of the goods in subsequent operations, e.g. during transport in roller tables, disturb, so that one has wung1 the material for the work step (s) following peeling by to make a separate straightening process machine-friendly again. This saber bow can be designed to be relatively strong in particular when the cutting performance is relatively large when peeling, be it due to a relatively large cutting depth, be it by a relatively large feed per revolution of the peeling head.

Der Erfindung liegt daher die Aufgabe zugrunde, die Schälmaschinenanlage gemäß Hauptpatent so weiterzubilden, daß das Schälgut nach dem Richten und Schälen die Schälmaschinenanlage ohne einen Säbelbogen verläßt, also, ohne nochmals gerichtet zu werden, weiteren Bearbeitungsvorgängen unterworfen werden kann. Die Lösung dieser Aufgabe ist erfindungsgemäß gekennzeichnet durch Antr ebsmittel für das Richtgut, die es mit einer Umlaufgeschwindigkeit in Drehung versetzen, die von der der Walzen der Gruppen der Richtmaschine abweicht, um eine Verdrehung des Richtgutes im Sinne von Torsion mindestens bis etwa zur Elastizitätsgrenze zu erreichen.The invention is therefore based on the object of the peeling machine system according to the main patent so that the peeled material after straightening and peeling leaves the peeling machine plant without a saber arch, that is, without having to straighten it again to become, can be subjected to further processing operations. The solution to this According to the invention, the task is characterized by means of propulsion for the material to be straightened, which set it in rotation at a speed equal to that of the rollers of the groups of the straightening machine deviates in the sense of a rotation of the object to be straightened of torsion at least up to approximately the elastic limit.

Da das zu richtende Gut in einer Richtmaschine gemäß Hauptpatent während des Richtens praktisch nicht in Richtung seiner Längsachse verschoben wird, weil die Walzen der Richtmaschine das zu richtende Gut nur im Sinne einer umlaufenden Biegebeanspruchung beeinflussen, läßt sich das Verdrehen des zu richtenden Gutes im Sinne Torsion ohne Schwierigkeiten dadurch erzielen, daß ein gesteuert antreibbares Spannfutter zum Erfassen des Richtgutes vorgesehen ist, wobei es an sich sekundär ist, an welcher Stelle ein solches Spannfutter angeordnet wird Weist das Richtgut im wesentEchen den gleichen Querschnitt auf dann reicht es aus, das eine Ende desselben in einem Spannfutter festzulegen, dass in an sich bekannter Weise antreibbar ist. Ändert sich der Querschnitt des zu richtenden Gutes in Längsrichtung, beispielsweise dadurch, daß der Querschnitt des zu richtenden Gutes im mittleren Bereich größer istaals im Bereich seiner beiden Enden, dann ist es zweckmäßig, das Spannfutter dem mittleren Bereich des Richtgutes zuzuordnen, also etwa in der Mitte der Längserstreckung der beiden Walzengruppen anzuordnen und so auszubilden, daß das zu richtende Gut in das Spannfutter quer zu dessen Drehachse eingelegt werden kann. Selbstverständlich ist in diesem Fall dafür zu sorgen, daß die Durchmesser der Walzen der beiden Walzengruppen so gewählt werden, daß die einzuleitende, umlaufende Biegebeanspruchung erzielt wird. Die an den Enden der Wellen der Walzengruppen vorgesehenen Walzen müssen also einen größeren Durchmesser aufweisen als die Walzen, die nähe der Mitte der Längserstreckung der Walzengruppen angeordnet sind.Since the goods to be straightened in a straightening machine according to the main patent during of straightening is practically not shifted in the direction of its longitudinal axis because the rolls of the straightening machine the goods to be straightened only in the sense of a rotating Bending stress can influence the twisting of the goods to be straightened achieve in the sense of torsion without difficulty in that a controlled drivable Chuck is provided for grasping the object to be straightened, it being secondary in itself is the point at which such a chuck is arranged essentially the same cross-section then it is sufficient to have one end of the same set in a chuck that can be driven in a manner known per se. If the cross-section of the goods to be straightened changes in the longitudinal direction, for example in that the cross-section of the goods to be straightened is larger in the central area istaals im Area of both ends, then it is expedient to assign the chuck to the middle area of the target, i.e. in the To be arranged in the middle of the longitudinal extension of the two groups of rollers and designed in such a way that that the goods to be straightened are inserted into the chuck transversely to its axis of rotation can. In this case it is of course necessary to ensure that the diameter of the rollers of the two roller groups are selected so that the one to be introduced is rotating Bending stress is achieved. Those provided at the ends of the shafts of the roller groups Rollers must therefore have a larger diameter than the rolls that are close the middle of the longitudinal extent of the roller groups are arranged.

Es hat sich bewährt, nach kurzem Anlauf nur noch das Spannfutter anzutreiben und dann die in der Anlaufphase zunächst angetriebene Walzengruppe frei mitlaufen zu lassen.It has proven useful to only drive the chuck after a short start-up and then the roller group initially driven in the start-up phase run freely allow.

Eine andere Lösung besteht darin, die Walzen der ortsfest gelagerten Gruppe mit einer Umlaufgeschwindigkeit anzutreiben, die von der Umlaufgeschwindigkeit der anderen, schwenkbar ge lagerten Gruppe abweicht. Zweckmäßig ist es, die Walzen der ortsfest gelagerten Gruppe mit einer höheren Umlaufgeschwindigkeit anzutreiben als die Walzen der schwenkbar angeordneten Gruppe.Another solution is to use the rollers that are fixedly mounted Drive group at a rotational speed that depends on the rotational speed the other, pivotably mounted group deviates. It is useful to use the rollers to drive the stationary group at a higher rotational speed than the rollers of the pivotal group.

Da die gegebenen Anweisungen ohne weiteres ausführbar sind, erübrigt sich deren Erläuterung anhand eines Ausführungsbeispieles.Since the instructions given can be carried out without further ado, they are not necessary their explanation based on an exemplary embodiment.
