Description

Die Rohrrichtmaschine für dünnwandige, im Durchmesser kleine Rohre nach der Erfindung verfolgt den Zweck, diese im voraufgegangenen Ziehprozeß krumm gewordenen Rohre so zu richten, daß diese unbeschädigt in gerade Lage gebracht werden. Dies wird nach der Erfindung dadurch erreicht, daß die Maschine, zwei gleiche, gegensinnig umlaufende, axial hintereinander angeordnete, Richtrollen tragende Rahmen aufweist.The pipe straightening machine for thin-walled pipes with a small diameter according to the invention has the purpose of making this crooked in the previous drawing process to straighten the pipes so that they are brought into a straight position undamaged. This is achieved according to the invention in that the machine, two of the same, is in opposite directions has circumferential, axially arranged one behind the other, straightening rollers supporting frame.

Rohrrichtmaschinen mit nur einem um das Werkstück umlaufenden, zu diesem gleichachsig angeordneten, Richtrollen tragenden Rahmen sind bekannt.Tube straightening machines with only one rotating around the workpiece this coaxially arranged frame carrying straightening rollers are known.

Es sind bei Rohrrichtmaschinen aber noch keine rechts und links um das zu richtende Rohr umlaufende Richtwerke, sondern nur Haspeln mit sich in einer Richtung um das zu richtende Rohr drehenden Richtwerken bekannt.With tube straightening machines, however, there are still no left and right turns the pipe to be straightened revolving straightening units, but only reels with them in one Direction around the pipe to be straightened rotating straightening known.

Bei diesen Richtwerken ist ein einwandfreies Richten dünner Rohre bei unbeschädigter Oberfläche sehr in Frage gestellt, wogegen sich das Rohr bei der Anordnung nach der Erfindung nicht drehen kann, -weil die beiden hintereinander angebrachten, entgegengesetzt umlaufenden Richtwerke das einwandfreie Richten des Rohres ausführen.With these straightening units, thin tubes are perfectly straightened very questionable if the surface is undamaged, whereas the pipe is at the arrangement according to the invention can not rotate because the two behind one another attached, oppositely rotating straightening units ensure the correct straightening of the Execute pipe.

Der Erfindungsgegenstand ist in der Zeichnung in einer Seitenansicht dargestellt.The subject of the invention is shown in the drawing in a side view shown.

Nach Einführung der Rohres a durch den Rolleneinzug b wird: dieses durch die in Pfeilrichtung rotierenden Richtwerke c und d durchgeschoben und in diesen gerichtet. Der Rolleneinzug f zieht bei diesem Richtvorgang das zu richtende Rohr a heraus.After the introduction of the tube a through the roller feed b becomes: this pushed through the straightening units c and d rotating in the direction of the arrow and in directed this. During this straightening process, the roller intake f pulls the one to be straightened Pipe a out.

Die Richtwerke bestehen aus Rahmen, in denen die Richtrollen gelagert sind.The straightening units consist of frames in which the straightening rollers are stored are.
