Definitions

  • the cutting wheels 34 are brought from an outer passive position, outside the periphery of the pipe holding opening of the implement, i.e. a position in which the cutting wheels will not obstruct a completely free introduction of the pipe to be cut, to a position in which the cutting wheels are located so far inside that periphery as required for the wheels to cut through the pipe wall during the following operational phase.
  • Fig. 5 The said pivoting of the wheel holders 30 is illustrated in Fig. 5, where the holder is shown by dot-and-dash lines in its swung-out position, while it it shoen in full lines in an operative position during or after cutting through the pipe wall.
  • the rotational speed should be considerably higher, e.g. of the magnitude 150 rpm. If it is desired to make use of approximately the same cutting velocity for pipes of different diameters, e.g. in the interval 50-160 mm, the speed of rotation should be adjustable, but it has been found that middle sized pipes, 110 mm, can be effectively worked within a speed interval of 100-200 rpm, and a suitable standard speed, therefore, may be 150 revolutions per minute.

Abstract

Afin d'éviter les problèmes posés par le raccourcissement de tuyaux métalliques inoxydables en les coupant transversalement, des machines à découper rotatives existent déjà et fonctionnent en poussant plusieurs roues coupantes contre une zone annulaire du tuyau et en les déplaçant le long de cette dernière. Cepedant, une telle opération nécessite une durée relativement longue, ainsi qu'une technicité particulière. D'après l'invention, on utilise un principe similaire mettant néanmoins en application un dosage automatique et réciproquement indépendant de la pression de coupe, ainsi que de la force ou de la vitesse de rotation respectivement, ce qui permet d'effectuer une coupe transversale rapidement et sans technicité particulière. Le dispositif comprend une bague de support extérieur (2) pourvue de mâchoires de serrage (4) servant à maintenir le tuyau en le centrant, ainsi que d'un élément annulaire (24) rotatif concentriquement et actionné par un moteur (28). Ledit élément annulaire (24) possède des supports (30) de roues coupantes (34) formant une saillie vers l'intérieur et chargée par ressort, ainsi que des moyens de commande (42, 38) servant à faire pivoter lesdits supports (30), de façon à pousser élastiquement lesdites roues coupantes contre le tuyau. Par l'intermédiaire d'une rotation rapide et motorisée de l'élément annulaire (24), les roues coupantes fonctionnent avec une pression élastique prédéterminée et relativement élevée contre le tuyau, ce qui permet de le sectionner transversalement en un minimum de temps.
