Description

und längs des Bügels 16, 16« verschiebbar angeschlossen. Der Bügel 16, 16 « ist um eine Achse 17, 17 α verschwenkbar. Der Bügel 16, 16 a mit seiner Verschwenkachse 17, 17 λ ist um eine vertikale, durch die Verschwenkachse 17, 17 « gehende Achse verdrehbar (Fig. 2, gestrichelte Darstellung). Zur Verschwenkung des Ständers 2, 2 « um die Achse /1-/1, A'-A' ist ein Verschwenkbock 13, 13« vorgesehen. Zur Halterung des zu schneidenden Rohres R sitzen auf der Schiene I Auflageböcke 5, S «. An Stelle oder neben diesen Auflageböcken 5, S α kann zur Halterung des Rohres aber auch ein auf der Führungsschiene beliebig einstellbarer Schwenkbock 8 mit einem Aufspaimbock 7 vorgesehen sein, der um die Achse A'-A' beliebig verschwenkbar ist.and connected to be displaceable along the bracket 16, 16 ″. The bracket 16, 16 ″ can be pivoted about an axis 17, 17 α. The bracket 16, 16 a with its pivot axis 17, 17 λ can be rotated about a vertical axis passing through the pivot axis 17, 17 ″ (FIG. 2, dashed illustration). To pivot the stand 2, 2 ″ about the axis / 1- / 1, A'-A ' , a pivot bracket 13, 13 ″ is provided. To hold the pipe R to be cut, there are support blocks 5, S ″ on the rail I. Instead of or in addition to these support brackets 5, S α , however, a swivel bracket 8, which can be adjusted as desired on the guide rail and which can be pivoted about the axis A'-A 'as desired, can also be provided to hold the pipe.

Mit einer solchen Rohrbrennschneidinascliine können beliebige Anpassungsschnitte ohne Abtastung des Rohres geschnitten werden. Die dafür notwendigen Einstellungen werden an den Hebelarmen 10, 10 η, 18, 18« und dem Bügel 16, 16« vorgenommen. Die Hebelarme 10, 10«, 18, 18« werden auf den Radius des zu schneidenden Rohres R eingestellt, während der Abstand des Bügels 16, 16« von eier Verschwenkachse 17, 17 α auf den Radius des mit dem zu schneidenden Rohr R zu verbindenden Rohres eingestellt wird. Wird nun über den Antriebsmotor 6, 6« die Welle 9, 9 α gedreht, dann beschreibt der Schneidbrenner 3,3 a die gewünschte Raumkurve.With such a pipe cutting line, any adaptation cuts can be made without scanning the pipe. The settings required for this are made on the lever arms 10, 10 η, 18, 18 "and the bracket 16, 16". The lever arms 10, 10 ″, 18, 18 ″ are set to the radius of the pipe R to be cut, while the distance of the bracket 16, 16 ″ from a pivot axis 17, 17 α to the radius of the pipe R to be connected to the cut Rohres is set. If the shaft 9, 9 α is now rotated via the drive motor 6, 6 ″, the cutting torch 3.3 a describes the desired three-dimensional curve.

Um auf einfache Weise den Schnittpunkt zweier unter einem beliebigen Winkel miteinander zu verbindenden Rohre festlegen zu können, ist längs der Auflageböcke 5, 5« und damit auch längs des zu schneidenden Rohres R ein Maßstab mit einer Längeneinteilung 12 vorgesehen. Der Ständer 2, 2 « trägt eine Markierung 14, 14«, die durch VerschiebungIn order to be able to determine the point of intersection of two pipes to be connected to one another at any angle in a simple manner, a scale with a length graduation 12 is provided along the supports 5, 5 'and thus also along the pipe R to be cut. The stand 2, 2 ″ bears a marking 14, 14 ″, which can be shifted

ίο des Ständers 2, 2« auf der Schiene 1 auf die gewünschte Stelle für den Schnittpunkt einstellbar ist. Vor dem Einstellen der Markierung 14 auf einen bestimmten Wert der Längeneinteilung 12 ist der Ständer 2 mittels ejnes Handrades 4, 4 « bis an einen Anschlag 15, 15« auf dem Schwenkbock 13, 13« gefahren. Wenn die Markierung 14 auf die Stelle der Längeneinteilung gebracht ist, in der sich die Verschwenkachse A-A, A'-A' mit der Achse B-B der Welle 9, 9« und der Achse D-D des zu schneidenden Rohres R in einem Punkt schneiden, dann wird der Schnitt am Rohr K so ausgeführt, daß es der gewünschten Länge entspricht. Sofern statt der Auflageböcke 5, 5 « ein Schwenkbock 8 Aufspannbock 7 vorgesehen ist, dann werden auch dessen Markierung 14 b auf die gewünschte Stelle der Anzeigevorrichtung 14,14 « eingestellt.ίο of the stand 2, 2 «on the rail 1 can be adjusted to the desired point for the point of intersection. Before setting the marking 14 to a certain value of the length graduation 12, the stand 2 is moved by means of a handwheel 4, 4 "to a stop 15, 15" on the swivel bracket 13, 13 ". If the marking 14 is brought to the point of the length division in which the pivot axis AA, A'-A ' with the axis BB of the shaft 9, 9 ″ and the axis DD of the pipe R to be cut intersect at one point, then the cut on the pipe K made so that it corresponds to the desired length. If, instead of the support frames 5, 5 ″, a swivel bracket 8, clamping bracket 7 is provided, then its marking 14 b is also set to the desired location on the display device 14, 14 ″.

Claims

Claim:

Flaming tube cutting machine with supports for the pipe to be cut and with a machining tool which is carried by a lever arm of an axially displaceable shaft rotatably mounted in a stand pivotable with respect to the pipe, as well as with a guide device connected to the stand, which has a pivotable bracket Distance from its pivot axis to the radius of the pipe to be connected to the pipe to be cut is adjustable and which is connected to the shaft via a further lever arm and a joint supported by this lever arm, which can be displaced along the bracket, the two lever arms being set to the radius of the pipe to be cut are adjustable, characterized in that a length graduation (12) is provided to define the intersection point (P) of the axes of the two pipes to be connected along the support frames (5, 5 a, 7, 8) and the one opposite the support frames (5, 5 a, 7, 8) movable and welded nkbaren stand (2, 2 a) carries a marking (14, 14 ") through which the pivot axis (/ 1- / 1, A'-A ') of the stand (2, 2 a) goes, which is with the axes (BB, DD) cut the shaft (9, 9 a) and the pipe to be cut (R) at point (P).

The invention relates to a pipe cutting machine with supports for the pipe to be cut Tube and with a machining tool that is axially displaceable by a lever arm and in a pivotable stand with respect to the tube is supported rotatably mounted shaft, as well as with a guide device connected to the stand, which has a pivotable bracket, whose Distance from its pivot axis to the radius of the pipe to be connected to the pipe to be cut Tube is adjustable and the one with the shaft via another lever arm and one of this Lever arm supported, along the bracket displaceable joint is connected, the two lever arms can be adjusted to the radius of the pipe to be cut.

Such a pipe cutting machine is known from German patent specification 511 153. With such a pipe cutting machine can without scanning the pipe to be cut after Adjustment of the lever arms and the bracket to the radii of each other under a certain Angle to be connected pipes made the desired cuts in the form of closed space curves will. With this machine you don't have to mark the space curves on the pipes. But still had to take into account the axial position of the cuts Diameter of the pipes can be determined graphically or by calculation. For simple, smooth miter cuts this did not present any difficulty, but in the case of intrusive and complex ones The definition of space curves was very cumbersome.

The invention is based on the object of providing a flame cutting machine of the type mentioned at the beginning Kind of set up so that the pipe is cut with it by simply setting the processing tool can be that the axes of the pipes to be connected to each other at a desired Cut point.

According to the invention, this object is achieved in that, in order to establish the point of intersection, the aciise of the two pipes to be connected to one another along the Auflageböckc a length division is provided and the stand, which can be moved and pivoted with respect to the bearing blocks, is a marking carries, through which the pivot axis of the stator goes, which is with the axes of the shaft and the pipe to be cut cuts at one point.

By simply setting the marking to a desired point of the length division, ' the cut to be made is placed on the pipe so that the intersection of the axes of the Pipes at a predetermined distance from a certain point, e.g. B. the end of the pipe, comes to rest. The invention makes it possible to carry out several cuts on the pipe at the same time, because the pipe to be cut lies at rest during processing. The pipe cutting machine then has one or more identically structured, stored and guided processing tools, whose markings carried by the stands are adjustable according to the length division.

In the following, the invention will be described in greater detail on the basis of a drawing showing an exemplary embodiment explained. In detail shows
