Description

Abschneidevorrichtung für von Rohrschweiß- oder Rohrformmaschinen erzeugte Rohrstränge. Um bei Rohrschweiß- und Rohrformmaschinen den Betrieb beim Abschneiden des Rohrstranges nicht unterbrechen zu müssen, ist bereits vorgeschlagen worden, die Abschnei.devorrichtung parallel zum Rohrstrang und mit gleicher Geschwindigkeit wie dieser zu bewegen, so daß das Abschneiden während des Betriebes erfolgen kann; die bekannten Einrichtungen dieser Art haben sich jedoch in die Praxis nicht einführen können. Bei ihnen wird ein die Schneidvorrichtung tragender Schlitten selbsttätig durch Spannmuffen mit dem Rohrstrang verbunden. und während des Schneidvorgangs mitgenommen, worauf die Spannmuffen durch besondere Einrichtungen gelöst werden müssen, 'damit der Schlitten in die Anfangsstellung zurückgeführt werden kann. Diese Arbeitsweise bedingt eine sehr verwickelte und teure Bauart.Cutting device for pipe welding or pipe forming machines generated pipe strings. In order to operate at the Not having to interrupt the cutting of the pipe string is already proposed the cutting device parallel to the pipe string and at the same speed how to move it so that cutting can take place during operation; however, the known devices of this type have not been introduced into practice can. With them, a carriage carrying the cutting device becomes automatic through clamping sleeves connected to the pipe string. and during the Cutting process taken, whereupon the clamping sleeves by special devices must be solved 'so that the carriage returned to the starting position can be. This way of working requires a very complex and expensive design.

Nach der Erfindung wird .der gleiche Erfolg in unvergleichlich einfacherer und _ billigerer Weise dadurch erzielt, daß man das freie Ende des Rohrstranges benutzt, um die Bewegung des Abschneidwerkzeuges unmittelbar mittels Anschlages hervorzurufen.According to the invention, the same success becomes incomparably easier and _ cheaper way achieved by having the free end of the pipe string used to control the movement of the cutting tool directly by means of a stop to evoke.

In der Zeichnung ist eine Ausführungsform der Einrichtung in. einer Seitenansicht dargestellt. Es bezeichnet a die Schweißmaschine, welche den Rohrstrang b erzeugt. An der Schweißmaschine a ist eine Führungsbahn c angeordnet, die außen an einem Bock d befestigt ist. Auf dieser Führungsbahn gleitet der Tragschlitten e des Rohrabs;chneiders, f ; am Tragschlitten e unten ist ein Elektromotor g befestigt, welcher mittels des Riemens h den Messerschlitten des Rohrabs.chneiders antreibt. Sobald' man den Rohrabschneider f durch Umlegen des Handhebels h anstellt, klemmt sich in bekannter Weise die (nicht gezeichnete) lediglich zum Zentrieren des Rohrs in der Schneidvorrichtung dienende Spannpatrone des Rohrabschneiders auf dem Rohr fest, und das Rohr wird während seiner Bewegung vom Schneidstahl abgestochen. Um die Schneidvorrichtung von dem Rohr mit gleicher Geschwindigkeit mitnehmen zu lassen, ist an dem Körper e des. Rohrabschneiders mittel, der Lasche i ein rinnenförmiges Verlängerungsstück l angebracht worden, dessen geschlossene Endwand so liegt, daß das freie Ende des Rohrstranges b dagegen stößt. Sobald dies geschieht, wird hierdurch der Rohrabschneider vom Rohre mit gleicher Geschwindigkeit. mitgenommen. Das Anstellen der Schneidvorrichtung zum Zwecke des. Abstechers des Rohrstückes erfolgt alsdann entweder von Hand oder .auch selbsttätig. Durch diese Einrichtung ist sichergestellt, daß alle Rohrabschnitte genau gleiche Länge haben.In the drawing, an embodiment of the device is shown in. A side view. It denotes the welding machine that produces the pipe string b. A guide track c is arranged on the welding machine a and is attached to the outside of a bracket d. The support carriage e of the pipe cutter, f ; An electric motor g is attached to the support carriage e below, which drives the knife carriage of the pipe cutter by means of the belt h. As soon as the pipe cutter f is turned on by turning the hand lever h, the clamping cartridge of the pipe cutter (not shown), which is only used to center the pipe in the cutting device, clamps on the pipe in a known manner, and the pipe is cut off by the cutting steel during its movement . In order to allow the cutting device to be carried along by the pipe at the same speed, a channel-shaped extension piece l has been attached to the body e of the pipe cutter medium, the tab i, the closed end wall of which is so that the free end of the pipe string b abuts against it. As soon as this happens, this causes the pipe cutter to pull off the pipe at the same speed. taken away. The adjustment of the cutting device for the purpose of cutting off the pipe section then takes place either by hand or automatically. This device ensures that all pipe sections have exactly the same length.
