Description

Beim autogenen Zerschneiden-von Blechen bestimmter Dicke besteht die Schwierigkeit, den Brenner oder dessen Träger mit gleicher Geschwindigkeit und ohne Schwingungen zu bewegen, so daß eine regelmäßige Schnittlinie gebildet wird. Die Erfindung bezweckt die Vermeidung dieses Übelstandes, um die Schnittflächen glatt, und gerade zu erzielen. Die Erfindung besteht darin, daß der Träger des Brenners mit einer Spitze oder einem Läufer versehen' ist, welcher auf eine bestimmte Temperatur gebracht wird, um in einen schmelzbaren Stoff allmählich einzudringen. Der Stoff in Berührung mit der Spitze oder dem Läufer schmilzt mit regelmäßiger Geschwindigkeit, welche die Geschwindigkeit der Bewegung der Spitze oder des Läufers begrenzt und regelt, so daß auch der damit verbundene Träger des Brenners ebenfalls mit einer geregelten Geschwindigkeit fortbewegt wird. Als schmelzbare Stoffe können z. B. das Stearin oder die Darcetylegierung benutzt werden.When cutting sheet metal with oxy-fuel Certain thickness there is the difficulty of the burner or its support with the same Move speed and without vibrations, so that a regular cutting line is formed. The aim of the invention is to avoid this inconvenience in order to achieve the cut surfaces smooth and straight. The invention is that the support of the burner with a tip or a Runner is provided ', which is brought to a certain temperature to be in gradually penetrate a fusible substance. The fabric in contact with the Tip or the runner melts at a regular rate, which is the speed the movement of the tip or the runner is limited and regulated, so that the associated carrier of the torch is also moved at a regulated speed. As meltable substances can e.g. B. the stearin or the Darcetyl alloy can be used.

Die zur Ausführung des Verfahrens dienende Vorrichtung kann beispielsweise aus einem Pantographen 1 bestehen, an welchem der Träger (z. B. eine Stange) des Brenners 3 angeordnet ist, und eine Spitze 2 oder ein Läufer 4 dieser Stange dringt in den schmelzbaren Stoff ein, wenn die Spitze erhitzt wird. Das Erhitzen erfolgt in einem bestimmten Abstand von der Spitze durch eine Heizquelle, welche beispielsweise mit demselben Gas gespeist wird wie der Schneidbrenner.The device used to carry out the method can, for example, from consist of a pantograph 1 on which the carrier (e.g. a rod) of the torch 3 is arranged, and a tip 2 or a runner 4 of this rod penetrates into the fusible Cloth when the tip is heated. The heating takes place in a certain Distance from the tip by a heating source, which for example with the same Gas is fed like the cutting torch.

Die Stange könnte auch durch andere Mittel geheizt werden, die eine regelmäßige Temperatur ermöglichen, z. B. durch inneren Umlauf einer heißen Flüssigkeit, ferner durch elektrische Widerstände usw.The rod could also be heated by other means that maintain a regular temperature enable, e.g. B. by internal circulation of a hot liquid, also by electrical resistances, etc.
