Description

La présente invention a pour objet un dispositif coupe-tube, de type à guillotine. On connaît déjà des dispositifs coupe-tube de type guillotine qui comprennent des moyens pour immobiliser le tube à couper, et une lame disposée dans un plan perpendiculaire à l'axe dudit tube, et mobile selon ce plan. De manière préférentielle, la lame présente deux tranchants faisant un angle saillant, et comporte de ce fait une pointe par l'intermédiaire de laquelle est amorcée la coupe.The present invention relates to a cutter device, guillotine type. Guillotine-type tube cutters are already known which comprise means for immobilizing the tube to be cut, and a blade disposed in a plane perpendicular to the axis of said tube, and movable along this plane. Preferably, the blade has two cutting edges at a projecting angle, and therefore has a point through which the cut is initiated.

L'attaque du tube par la pointe de la lame permet de limiter la déformation du tube, essentiellement un aplatissement, à l'amorce de la coupe, sans toutefois supprimer complètement cette déformation. Pour pallier cet inconvénient il est parfois proposé d'entailler le tube au niveau de la zone d'attaque de la pointe de la lame, ce qui est réalisé par l'intermédiaire d'une lame secondaire qui agit en tirant, tangentiellement au tube. Si cette solution améliore la coupe, elle présente l'inconvénient de rendre le dispositif plus complexe, puisqu'il faut ajouter, aux moyens d'entraînement de la lame principale, des moyens d'entraînement de la lame secondaire, ainsi que des moyens de coordination des mouvements. La présente invention a pour but de proposer un dispositif coupe-tube permettant de remédier à cet inconvénient 25 tout en conservant une parfaite qualité de coupe. Le dispositif coupe-tube selon l'invention comporte: - des moyens de réception du tube à couper, - une première lame disposée dans un plan perpendiculaire à l'axe dudit tube lorsqu'il est placé dans lesdits moyens de 30 réception, mobile selon ledit plan, et présentant deux tranchants faisant un angle saillant qui crée une pointe dirigée vers lesdits moyens de réception, - une lame secondaire, disposée selon le même plan que ladite première lame et en sorte que son tranchant puisse venir 35 au contact dudit tube et y créer, lors d'un déplacement axial tangent audit tube, une amorce de découpe à l'aplomb de ladite pointe, et il se caractérise essentiellement en ce que ladite première lame et ladite lame secondaire comportent chacune des moyens qui coopèrent entre eux en sorte de permettre que le mouvement de ladite première lame en direction desdits moyens de réception, génère le déplacement de ladite lame secondaire afin qu'elle puisse réaliser ladite amorce de découpe préalablement à l'entrée en contact de ladite première lame avec ledit tube.The attack of the tube by the tip of the blade allows to limit the deformation of the tube, essentially a flattening, at the beginning of the cut, without, however, completely suppressing this deformation. To overcome this drawback it is sometimes proposed to cut the tube at the leading edge of the tip of the blade, which is achieved by means of a secondary blade which acts by pulling tangentially to the tube. If this solution improves the cut, it has the disadvantage of making the device more complex, since it is necessary to add, to the drive means of the main blade, means for driving the secondary blade, as well as means for coordination of movements. The present invention aims to provide a tube cutter device to overcome this disadvantage 25 while maintaining a perfect cutting quality. The tube cutter device according to the invention comprises: - means for receiving the tube to be cut, - a first blade disposed in a plane perpendicular to the axis of said tube when it is placed in said receiving means, mobile according to said plane, and having two sharpening edges forming a point directed towards said receiving means, - a secondary blade disposed in the same plane as said first blade and so that its cutting edge can come into contact with said tube and there, during an axial displacement tangential to said tube, creating a cutting primer directly above said tip, and characterized essentially in that said first blade and said secondary blade each comprise means which cooperate with each other so as to allowing the movement of said first blade towards said receiving means to cause the displacement of said secondary blade so that it can perform said primer cutting before contacting said first blade with said tube.

Selon une caractéristique additionnelle du dispositif coupe-tube selon l'invention, la lame secondaire comporte une surface de guidage, de direction oblique par rapport à son sens de déplacement, et contre laquelle une partie de la première lame vient prendre appui et glisser lors de son déplacement en direction du moyen de réception du tube, en sorte de chasser la lame secondaire. Les avantages et les caractéristiques du dispositif coupe-tube selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel 20 en représente un mode de réalisation non limitatif. Dans le dessin annexé la figure unique représente une vue schématique en plan du dispositif coupe-tube selon l'invention. En référence à cette figure, on peut voir que le dispositif coupe-tube selon l'invention comprend dans un bâti 1, 25 des moyens 2 de réception et de maintien d'un tube à couper, non représenté, ainsi qu'une première lame 3 et une lame secondaire 4. La première lame 3 comporte deux tranchants 30 et 31 faisant entre eux un angle et créant ainsi une pointe 32, 30 laquelle est dirigée vers les moyens de réception 2. La première lame 3 est guidée et mobile dans le sens de la flèche C, dans un plan perpendiculaire à l'axe des moyens de réception 2, et en sorte que la pointe 32 et les tranchants 30 et 31 traversent les moyens de réception 2. 35 La lame secondaire 4 comporte un tranchant 40, et plus particulièrement, mais non limitativement, en forme de crochet.According to an additional feature of the pipe cutter device according to the invention, the secondary blade comprises a guide surface, obliquely direction relative to its direction of movement, and against which a portion of the first blade comes to bear and slide during its movement towards the receiving means of the tube, so as to drive the secondary blade. The advantages and characteristics of the pipe cutter device according to the invention will become more clearly apparent from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof. In the attached drawing the single figure shows a schematic plan view of the pipe cutter device according to the invention. With reference to this figure, it can be seen that the pipe cutter device according to the invention comprises, in a frame 1, means 2 for receiving and holding a cutting tube, not shown, and a first blade 3 and a secondary blade 4. The first blade 3 has two cutting edges 30 and 31 forming an angle between them, thereby creating a point 32, which is directed towards the receiving means 2. The first blade 3 is guided and movable in the direction of the arrow C, in a plane perpendicular to the axis of the receiving means 2, and so that the tip 32 and the cutting edges 30 and 31 pass through the receiving means 2. The secondary blade 4 comprises a cutting edge 40, and more particularly, but not exclusively, in the form of a hook.

La lame secondaire 4 est guidée et mobile dans le même plan que celui de la première lame 3, dans le sens de la flèche A, à savoir perpendiculairement au sens de déplacement C de la première lame 3, et en sorte que son bord 41, celui qui comporte le tranchant 40, soit tangent à l'emplacement que doit occuper le tube dans les moyens de réception 2. La lame secondaire 4 comporte également un bord 42, oblique par rapport au sens de déplacement, et faisant un angle aigu avec le bord 41.The secondary blade 4 is guided and movable in the same plane as that of the first blade 3, in the direction of the arrow A, namely perpendicular to the direction of displacement C of the first blade 3, and so that its edge 41, the one having the cutting edge 40, is tangent to the location that the tube must occupy in the receiving means 2. The secondary blade 4 also comprises an edge 42, oblique to the direction of movement, and making an acute angle with the edge 41.

En fait, le bord 42 est parallèle au tranchant 31 de la première lame 3, avec lequel il coopère en glissement. On comprendra que le déplacement C de la première lame 3 en direction des moyens de réception 2, provoque, au travers du contact glissant du tranchant 31 avec le bord 42, la chasse de la lame secondaire 4 dans le sens C, avec pour conséquence la réalisation, par le tranchant 40, d'une amorce de coupe dans laquelle va venir s'insérer la pointe 32 de manière que les tranchants 30 et 31 réalisent la coupe. L'angle que fait le tranchant 31 avec l'axe principal de la première lame 3, et par conséquent l'angle que fait le bord 42 avec l'axe principal de la lame secondaire 4, sont choisis en sorte d'assurer le déplacement de la lame secondaire 4, tout en garantissant un appui suffisant sur le tube pour y créer l'amorce de coupe.25In fact, the edge 42 is parallel to the cutting edge 31 of the first blade 3, with which it cooperates slidably. It will be understood that the displacement C of the first blade 3 towards the receiving means 2, causes, through the sliding contact of the cutting edge 31 with the edge 42, the flushing of the secondary blade 4 in the direction C, with the consequence that the realization, by the edge 40, a cutting primer in which will be inserted the tip 32 so that the cutting edges 30 and 31 make the cut. The angle made by the cutting edge 31 with the main axis of the first blade 3, and consequently the angle made by the edge 42 with the main axis of the secondary blade 4, are chosen so as to ensure the displacement of the secondary blade 4, while ensuring sufficient support on the tube to create the cutting primer.
