Definitions
- the invention relates to a cutting tool for severing open cross section profiles such as, for example, U-shaped rails for mounting partitions or false ceilings.
- the document US 5,010,795 shows a cutting tool for cutting open cross-section profiles, the tool comprising a base, a support attached to the base and a blade with two opposite ends, the blade being mounted on the support so as to be movable in a plane cutting between an open position to receive, between the support and the blade, a section which must be sectioned, and a closed position at the end of a cut, the support comprising a matrix intended to be capped by the profile to be sectioned and provided with a slot for receiving the blade during cutting, the blade being pivotally mounted about an axis transverse to the cutting plane of the blade, and having a punch located between the two opposite ends, and two cutting edges plates extending from the punch respectively towards one or the other of the two ends, the flat cutting edge extending towards the axis about which the blade pivots, being provided, punch, first of a short concave section.
- the object of the invention is to provide a cutting tool for cutting profiles without deforming or forming long chips.
- the object of the invention is achieved with a cutting tool according to claim 1.
- the support comprises a matrix intended to be capped by the profile to be cut and provided with a slot intended to receive the blade during a cutting
- the blade comprises a punch located between its two opposite ends, and two flat cutting edges extending from the punch respectively towards one and towards the other of the two ends.
- the cutting tool according to the invention is therefore a shearing tool according to two parallel sectioning planes passing through a longitudinal axis of the profile to be sectioned. Due to the small distance between the two sectioning planes and since this makes it possible to simplify the description of the invention without jeopardizing its accuracy, the present description refers thereafter to a single sectioning plane, also called cutting plane.
- the shearing is effected between a matrix provided with a slot and thus forming two fixed blades mounted on the support, and a movable blade having two flat cutting edges, thus having two cutting edges each, and which is intended to engage between the two fixed blades of the matrix.
- the blade is pivotally mounted on the support or - according to an alternative embodiment not described in detail - slidably mounted between two amounts of the support.
- the matrix has a shape adapted to the cross section of the sections to be cut, so that at least the greater part of the different wings of a profile placed on the matrix, preferably even all the wings of the profile, can be supported on the matrix and thus be exposed as little as possible to the risk of deformation.
- the support of one or the other of the wings of a profile can be exerted in addition to the support, as will be described later with reference to the drawings.
- the matrix is a removable element that can be replaced by a matrix of another shape or having other dimensions, or the matrix comprises several heads each of which is adapted to a specific profile, as will be explained in more detail later in the description.
- the tool according to the invention is not limited to the cutting of simple U-shaped sections. It may instead be adapted also to profiles having no planar base or occupying only part of the matrix, as will also be described later with reference to the drawings. Note also that the use of removable matrices contributes to a longer life of the tool because of being able to easily replace a worn matrix.
- the term "flat" characterizes a cutting edge having a certain width, as opposed to a cutting edge having only a net like the blade of a knife.
- each of the cutting edges extends perpendicularly with respect to the cutting plane of the tool.
- the cutting tool according to the invention is described below with the aid of a preferred embodiment of the invention, namely with a pivoting blade and with a four-head matrix for four different types of profiles. It goes without saying that this embodiment has been chosen arbitrarily and that it has no limiting character for the invention.
- the tool according to the invention is presented hereinafter as being designed more particularly for the cutting of metal profiles, where the chips are allowed to bend - as explained later - and then remain folded.
- the tool according to the invention can also be used for cutting plastic profiles, where the chips are allowed to bend in a similar manner, but do not generally remain folded.
- a cutting tool according to the invention for cutting profiles comprises a base 1 T-shaped and a blade 2 pivotally mounted on a support 3 attached to the base 1, for example by means of two bolts 4, 5.
- the blade 2 pivots around an axis 6 passing through the support 3.
- This arrangement makes it possible to move the blade 2 between an open position to receive, between the blade 2 and the support 3, a profile P (see FIG. figure 6 ) to be sectioned, and a closed position at the end of a cut.
- the blade 2 is shown in the open position for example on the figure 1 , in an almost closed position on the figure 7 and in the closed position on the figure 10H .
- the displacement of the blade 2 takes place along a vertical section plane constituting at the same time a plane of symmetry for the support 3 and for a matrix 7 intended to produce together with the blade 2, during the cutting of a profile P, the shear effect.
- the support 3 is formed by two plates or flanges 31, 32.
- Each of the flanges 31, 32 comprises a rectangular cutout 33 in which is housed the matrix 7.
- the two flanges 31, 32 are arranged parallel to each other and spaced from each other to receive between them the blade 2 during cutting or when the tool is placed in the closed position, for example to be stored or to be transported.
- the blade 2 is mounted close to an edge 35 of two vertical outer edges 34, 35 of the support 3 and so as to be pivotable towards the other vertical edge 34 of the support 3, the pivot axis being formed by a bolt 6 traversing the support 3 transversely to the cutting plane.
- the two flanges 31, 32 have recesses 36, 37 in flare.
- the matrix 7 is formed by two flanges 71, 72 arranged parallel to one another and spaced from one another so as to form a slot 73 in which the blade 2 engages during a cut.
- the two flanges 71, 72 have the same height and thus have a horizontal support plane, as it seems to be obvious when it is necessary to lay the profile horizontally on the matrix to cut it along its cross section, so vertically. It follows that when cutting sections in an oblique cutting plane is advantageously used a matrix whose two flanges have different heights and thus form an inclined support plane.
- the tool according to the embodiment shown in the drawings comprises a matrix 7 provided with a plurality of heads and which is rotatably mounted about an axis 8 passing through the support 3. More particularly, the matrix 7 is shown with four heads 7A to 7D arranged in a cross (see figure 5 ). However, without departing from the principle of the present invention, the matrix may equally well be provided with another number of heads, for example two or three heads.
- Each of the two flanges 71, 72 has the shape of a cross having four heads 7A to 7D of shapes and / or different dimensions corresponding to four or even five different types of sections to be sectioned.
- the two flanges 71, 72 are mounted rotating about an axis 8 passing through two flanges 38 arranged projecting and secured respectively to one and the other of the two flanges 31, 32 of the support 3.
- the two flanges 38 may be patches and attached to the support 3 by welding or be obtained by stamping the flanges 31, 32 of the support 3.
- the two flanges 71, 72 of the matrix 7 are mounted between the two flanges 38 so as to be put in two different positions.
- the two flanges 71, 72 are spaced from one another, they are then in the cutting position.
- each of the two flanges 71, 72 is engaged in the cutout 33 of the corresponding flange 31 or 32 of the support 3 and is aligned therewith.
- the two flanges of the matrix are at the same time prevented from changing position.
- the two flanges 71, 72 of the matrix 7 are brought closer to one another in order to be able to turn the die 7 to another position, that is to say when another of the four heads must be placed in the cutting position.
- the two flanges are advantageously, but no exclusively, mounted on an 8-pin both the flanges 31, 32 of the support 3 and the two flanges 71, 72 of the matrix 7 and a helical spring 74 disposed between the two flanges 71, 72 of the matrix 7.
- the spindle 8 is provided with a thread for receiving a nut by which it is possible to adjust the effective length of the spindle.
- the spindle On the other of its two ends, the spindle is provided with a cam lever 81 by means of which the two flanges 71, 72 are brought closer to each other against the elastic stress of the coil spring 74.
- the spindle On a central part of its length, where it is in contact with the flanges 71, 72 of the die 7, but advantageously outside the two end parts where the pin 8 rotates in the flanges 31, 32 of the support 3, and of course with the exception of the threaded portion, the spindle has a hexagonal cross section 82 whose dimensions correspond to those of a central orifice of each of the flanges 71, 72 of the die 7 to be traversed by the pin 8.
- the pin 8 and the central orifices of the flanges 71, 72 may have other shapes of cross section, for example rectangular, in particular square, or triangular. Indeed, regardless of the precise polygonal shape of the cross section of the pin 8 and orifices, it is thanks to it that the pin and the two flanges 71, 72 of the matrix 7 are integral in rotation.
- the figure 5 represents a complete flange 71 or 72 of the matrix 7 with the four heads 7A to 7D.
- the fourth head 7D is formed for a single section U which is wider than the profile for which is made the head 7A and whose wings are not provided returns.
- the blade 2 is connected to a lever arm 9.
- the arm is offset relative to the pivot axis 6 of the blade 2 for ease of use of the tool and in particular to generate a better support on the blade during cutting.
- the blade 2 comprises, as is shown in detail on the figure 8 , in addition to a blade body 21 provided with two cutting edges 24, 25 to effect cutting, a first connecting piece 22 connecting the arm 9 to the blade body 21 and a second connecting piece 23 connecting the arm 9 to a fixing appendix 26 for pivotally mounting the blade 2 on the support 3.
- the two connecting pieces 22, 23 are joined in a flange 27 provided with two orifices 28 for fixing the arm 9 to the blade 2.
- the blade 2 thus has a total length L between two opposite ends A, B which clearly exceeds a useful length LL of the blade, determined by the largest radial extent of the two cutting edges 24, 25 of the blade 2, and a total height H of the same order of size as the length L of the blade 2.
- the figure 6 shows more particularly that the blade 2 is mounted on the support 3 by introducing the attachment appendage 26 between two protuberances 39A, 39B of the two plates 31, 32 of the support 3, the two protuberances 39A, 39B each having a shape corresponding to that of the appendix 26 of the blade 2, and by passing through the appendage 26 and the two protuberances 39A, 39B by a bolt 6 serving as the axis of pivoting of the blade 2.
- the figure 6 also suggests also an alternative embodiment in which the base 1 can be extended in the plane of the section by a foot 12 having a transverse portion 13 to give the cutting tool a better stability.
- the foot 12 can be made with a fixed length or retractable, for example telescopic.
- the figure 8 shows the blade body 21 as being made in two parts 21A, 21B according to a first embodiment of the blade 2 according to the invention.
- the blade 2 is made in one piece.
- the blade body 21 comprises a punch 211 situated between the two opposite ends A, B of the blade 2 and from which the two flat cutting edges 24, 25 extend respectively towards the end A and towards the end B.
- Each of the two cutting edges 24, 25 comprises, while moving towards the corresponding end A or B of the blade 2, a convex section followed by a concave section.
- the punch 211 of the blade 2 is disposed of in order to first come into contact with the section P to be sectioned (see figure 6 ) and also in order to begin the sectioning of it (see Figures 10A, 10B ).
- each of the two cutting edges 24, 25 cuts the profile in the corresponding direction, ie the cutting edge 24 towards the end A and the cutting edge 25 towards the end B of the blade 2. This is made by two convex sections 213, 215 which extend, each in its direction, from the punch 211.
- the cutting edge 24 is provided, starting from the punch 211, first of a short concave section 212 before the convex section 213 begins. This is due to the fact that the blade 2 is formed to be pivotally mounted. As a result, the punch 211 is oriented along the tangent T to the pivot radius R passing through the center 261 of the appendix 26. An immediate start of the convexly shaped cutting edge 24 would be detrimental to the shear efficiency of the cutting edge.
- the punch 211 would be oriented in the direction of translation and the two cutting edges could be symmetrical with respect to the other and from the punch 211 in convex shape without affecting the sectioning of the section.
- the embodiment of blade 2 in two parts, in particular with a portion 21B having the concave section 216, may contribute to facilitate the manufacture of the blade, for example when the cutting means available to cut the blade, do not lend themselves to a tight shape of the cutting edge 25 as shown.
- the chips C1, C2 are first held in two recesses V1, V2 formed by the concave sections 214, 216 which each form a loop having an extent corresponding to at least one half circle or one another comparable curved shape, before being removed when the blade 2 is rotated to its open position to accommodate another P section to be sectioned.
- the figure 9 represents, as a variant of the blade 2 according to the figure 8 a second blade 102 which, as opposed to the first blade 2, is a "full" blade, i.e., its blade body 121 is directly connected to an arm 9, hence without connecting pieces.
- the blade body 121 is shown as being made in two parts 121A, 121B according to a second embodiment of the blade 102 according to the invention.
- the blade 102 may equally well be made in one piece.
- the blade body 121 comprises a punch 211 situated between the two opposite ends A, B of the blade 102 and from which two flat cutting edges 124, 125 extend respectively toward the end A and towards the end B.
- Each of the two cutting edges 124, 125 comprises, evolving towards the corresponding end A or B of the blade 102, a convex section followed by a concave section according to the same provisions and to produce the same effects as that has been described for blade 2.
- the realization of the blade of the tool of the invention according to the variant shown on the figure 9 brings the particular advantage of being able to choose two different materials for the part 121A and for the part 121B and to be able to give more hardness to the portion 121B comprising the punch 211 and the convex sections of the two cutting edges 124, 125, as 121A.
- the figure 12 represents, as a variant of the blade 102 according to the figure 9 , and likewise alternatively of the blade 2 according to the figure 8 a third blade 202 which is distinguished from the first two by the presence of an ejector finger 29.
- the blade 202 is shown mounted in the tool, the flange 32 of the support 3 having been omitted, and in an open position of the tool for setting up a section to be cut. The blade is therefore not in the maximum open position of the tool.
- the blade 202 comprises a blade body 221 in two parts 221A, 221B whose part 221B comprises the punch 211 and the first part of each of two cutting edges 224, 225 of the blade.
- the two cutting edges 224, 225 are shaped to sever the profile, from a point of impact of the punch 211 on the profile, in two opposite directions.
- Each of the two cutting edges is provided, away from the punch 211, a concave section forming respectively a hollow V1 and a hollow V2, in which the hollow chips resulting from the cut are held before being removed when the blade is pivoted to his open position.
- the ejector finger 29 which is formed in one piece with the body of the blade 21 and whose free end is advantageously, but not necessarily, angled approximately towards the point 211, raises the chip and the ejects the tool.
- the figure 13 represents a tool according to the invention which in most of its characteristics resembles the tool according to the figure 12 and is shown as this in the partially disassembled state, but in a perspective view.
- the tool is equipped with a ruler 40 to facilitate the cutting of a profile to a predetermined length.
- the rule 40 comprises a rod 41 slidably mounted in a support 42 and, at one of its two opposite ends, a stop 43.
- the rod 41 is advantageously, but not necessarily, graduated and has, advantageously but not necessarily, a rectangular section (square in the example shown) or oval according to the shape of the through hole made in the support 42 and, where appropriate, according to the precise design of the tool, in the flanges 31, 32 of the support 3 of the tool .
- This arrangement of the invention ensures that the stop 43 is always in horizontal position without the clamping means whose support 42 is provided to be able to stop the rod in different positions corresponding to different cutting lengths of a profile, must not develop. a clamping force such that the rod can be effectively prevented from rotating and leaving the stop in the pendulum position.
- the figure 14 represents a tool according to the invention which in most of its characteristics resembles the tool according to the figure 13 , but which is equipped with a fourth blade 302.
- the blade 302 differs from the first three by the absence of a second hollow V2, in which the chips resulting from cutting are maintained before being removed when the blade is rotated to its open position.
- the blade 302 comprises a blade body 321 with a punch 311 from which two flat cutting edges 324, 325 respectively extend towards one and towards the other of the two ends A, B of the blade (see FIG. figure 8 ).
- the first cutting edge 324 is essentially straight (after a concave start as on the punch 211) and is followed by a cutting edge portion 326 first concave then convex and ending in an ejector finger 29 corresponding to that of the blade 202 (see figure 12 ).
- the second cutting edge 325 corresponds to the cutting edge 225 of the blade 202 and forms a single recess V2 in which the chips resulting from cutting are held before being removed when the blade is pivoted to its open position.

Description
L'invention concerne un outil de coupe pour sectionner des profilés à section transversale ouverte tels que, par exemple, des rails en U pour le montage de cloisons ou de faux plafonds.The invention relates to a cutting tool for severing open cross section profiles such as, for example, U-shaped rails for mounting partitions or false ceilings.
Pour la découpe de tels profilés, on utilise traditionnellement une scie, un disque ou une cisaille. Cependant, quel que soit le type d'outil choisi, la découpe déforme le profilé, que ce soit en raison d'une faible rigidité du matériau ou en raison de la forme complexe du profilé et l'impossibilité qui en découle d'appliquer l'outil sur toutes les parties du profilé sous le meilleur angle. En même temps, la découpe avec certains de ces outils traditionnels produit des copeaux dangereux en raison de la longueur de leurs bords coupants.For cutting such profiles, traditionally used a saw, a disc or shears. However, regardless of the type of tool chosen, the cut deforms the profile, either because of a low stiffness of the material or because of the complex shape of the profile and the impossibility that ensues to apply it. tool on all parts of the profile at the best angle. At the same time, cutting with some of these traditional tools produces dangerous chips because of the length of their sharp edges.
Le document
Le but de l'invention est de proposer un outil de coupe permettant de découper des profilés sans les déformer ni former des copeaux longs.The object of the invention is to provide a cutting tool for cutting profiles without deforming or forming long chips.
Le but de l'invention est atteint avec un outil de coupe suivant la revendication 1.The object of the invention is achieved with a cutting tool according to
Selon l'invention, le support comprend une matrice destinée à être coiffée par le profilé à sectionner et pourvue d'une fente destinée à recevoir la lame au cours d'une découpe, et la lame comporte un poinçon situé entre ses deux extrémités opposées, et deux tranchants plats s'étendant à partir du poinçon respectivement vers l'une et vers l'autre des deux extrémités.According to the invention, the support comprises a matrix intended to be capped by the profile to be cut and provided with a slot intended to receive the blade during a cutting, and the blade comprises a punch located between its two opposite ends, and two flat cutting edges extending from the punch respectively towards one and towards the other of the two ends.
L'outil de coupe selon l'invention est donc un outil à effet de cisaillement suivant deux plans de sectionnements parallèles traversant un axe longitudinal du profilé à sectionner. En raison de la faible distance entre les deux plans de sectionnement et puisque cela permet de simplifier la description de l'invention sans que cela ne nuise à son exactitude, la présente description se réfère par la suite à un plan unique de sectionnement, également appelé plan de coupe. Le cisaillement est effectué entre une matrice pourvue d'une fente et formant ainsi deux lames fixes montées sur le support, et une lame mobile ayant deux tranchants plats, ayant donc deux bords coupants chacun, et qui est destinée à s'engager entre les deux lames fixes de la matrice. La lame est montée pivotante sur le support ou - selon un mode de réalisation alternatif non décrit en détail - montée coulissante entre deux montants du support.The cutting tool according to the invention is therefore a shearing tool according to two parallel sectioning planes passing through a longitudinal axis of the profile to be sectioned. Due to the small distance between the two sectioning planes and since this makes it possible to simplify the description of the invention without jeopardizing its accuracy, the present description refers thereafter to a single sectioning plane, also called cutting plane. The shearing is effected between a matrix provided with a slot and thus forming two fixed blades mounted on the support, and a movable blade having two flat cutting edges, thus having two cutting edges each, and which is intended to engage between the two fixed blades of the matrix. The blade is pivotally mounted on the support or - according to an alternative embodiment not described in detail - slidably mounted between two amounts of the support.
La matrice présente une forme adaptée à la section transversale des profilés à sectionner, afin qu'au moins la plus grande partie des différentes ailes d'un profilé posé sur la matrice, de préférence même toutes les ailes du profilé, puissent prendre appui sur la matrice et soient ainsi exposés le moins possible au risque d'une déformation. Dans certains cas, selon la complexité de la forme du profilé, l'appui de l'une ou l'autre des ailes d'un profilé peut être exercé en plus sur le support, comme cela sera décrit plus loin en référence au dessins.The matrix has a shape adapted to the cross section of the sections to be cut, so that at least the greater part of the different wings of a profile placed on the matrix, preferably even all the wings of the profile, can be supported on the matrix and thus be exposed as little as possible to the risk of deformation. In some cases, depending on the complexity of the shape of the profile, the support of one or the other of the wings of a profile can be exerted in addition to the support, as will be described later with reference to the drawings.
Lorsque l'outil selon l'invention doit servir à sectionner des profilés de différentes formes et/ou différentes dimensions, la matrice est un élément amovible pouvant être remplacée par une matrice d'une autre forme ou ayant d'autres dimensions, ou encore, la matrice comprend plusieurs têtes dont chacune est adaptée à un profilé spécifique, comme cela sera expliqué en davantage de détails, plus loin dans la description. L'outil selon l'invention n'est d'ailleurs pas limité à la découpe de profilés en U simple. Il peut au contraire être adapté aussi à des profilés n'ayant pas de base plane ou occupant une partie de la matrice seulement, comme cela sera également décrit plus loin en référence aux dessins. Notons accessoirement que l'utilisation de matrices amovibles contribue à une durée d'utilisation plus longue de l'outil du fait de pouvoir remplacer facilement une matrice usée.When the tool according to the invention is used to cut profiles of different shapes and / or different dimensions, the matrix is a removable element that can be replaced by a matrix of another shape or having other dimensions, or the matrix comprises several heads each of which is adapted to a specific profile, as will be explained in more detail later in the description. The tool according to the invention is not limited to the cutting of simple U-shaped sections. It may instead be adapted also to profiles having no planar base or occupying only part of the matrix, as will also be described later with reference to the drawings. Note also that the use of removable matrices contributes to a longer life of the tool because of being able to easily replace a worn matrix.
En ce qui concerne la lame de l'outil selon l'invention et plus particulièrement les deux tranchants de celle-ci, il convient de préciser que, dans le contexte de la présente invention, le terme « plat » caractérise un tranchant ayant une certaine largeur, par opposition à un tranchant n'ayant qu'un filet tel la lame d'un couteau. De plus, dans le cadre de la présente invention, chacun des tranchants s'étend perpendiculairement par rapport au plan de sectionnement de l'outil. La forme particulière de la lame et l'effet qu'elle produit selon les dispositions de l'invention seront décrits plus loin en référence aux dessins.With regard to the blade of the tool according to the invention and more particularly the two cutting edges thereof, it should be noted that, in the context of the present invention, the term "flat" characterizes a cutting edge having a certain width, as opposed to a cutting edge having only a net like the blade of a knife.

L'outil de coupe selon l'invention est décrit ci-après à l'aide d'un mode de réalisation préféré de l'invention, à savoir avec une lame pivotante et avec une matrice à quatre têtes pour quatre types de profilés différents. Il va sans dire que cet exemple de réalisation a été choisi arbitrairement et qu'il n'a aucun caractère limitatif pour l'invention.The cutting tool according to the invention is described below with the aid of a preferred embodiment of the invention, namely with a pivoting blade and with a four-head matrix for four different types of profiles. It goes without saying that this embodiment has been chosen arbitrarily and that it has no limiting character for the invention.
De plus, l'outil selon l'invention est présenté ci-après comme étant conçu plus particulièrement pour la découpe de profilés métalliques, où les copeaux se laissent plier - comme expliqué plus loin - et restent ensuite pliés. Toutefois, l'outil selon l'invention peut également être utilisé pour la découpe de profilés en plastique, où les copeaux se laissent plier de manière analogue, mais ne restent généralement pas pliés.In addition, the tool according to the invention is presented hereinafter as being designed more particularly for the cutting of metal profiles, where the chips are allowed to bend - as explained later - and then remain folded. However, the tool according to the invention can also be used for cutting plastic profiles, where the chips are allowed to bend in a similar manner, but do not generally remain folded.
Enfin, l'outil de coupe selon l'invention est représenté dans les dessins et décrit ci-après dans une de plusieurs positions d'utilisation possible, à savoir posé sur un sol horizontal. Aussi, les indications de direction ou d'orientation « horizontal » et « vertical » se réfèrent à cette position d'utilisation arbitrairement choisie pour simplifier la description de l'invention, mais n'ont pour autant aucun caractère limitatif.Finally, the cutting tool according to the invention is shown in the drawings and described hereinafter in one of several positions of possible use, namely placed on a horizontal floor. Also, the indications of direction or orientation "horizontal" and "vertical" refer to this use position arbitrarily chosen to simplify the description of the invention, but are in no way limiting in nature.

Comme les
De manière analogue aux dispositions du support 3, la matrice 7 est formée par deux flasques 71, 72 disposés parallèlement l'un à l'autre et espacés l'un de l'autre de manière à former une fente 73 dans laquelle la lame 2 s'engage lors d'une découpe.In a similar manner to the provisions of the
Comme cela est visible sur les dessins, par exemple sur la
Alors qu'il est concevable, selon la présente invention, que chacun des deux flasques de la matrice soit solidaire d'une plaque correspondante 31 ou 32 du support 3, ou y soit attachée de manière amovible, l'outil selon le mode de réalisation représenté dans les dessins comprend une matrice 7 pourvue de plusieurs têtes et qui est montée tournante autour d'un axe 8 traversant le support 3. Plus particulièrement, la matrice 7 est représentée avec quatre têtes 7A à 7D disposées en croix (voir
Chacun des deux flasques 71, 72 a la forme d'une croix présentant quatre têtes 7A à 7D de formes et/ou de dimensions différentes correspondant à quatre ou même cinq types différents de profilés à sectionner. Les deux flasques 71, 72 sont montés tournants autour d'un axe 8 traversant deux brides 38 disposées en saillie et solidaires respectivement de l'un et de l'autre des deux flasques 31, 32 du support 3. Les deux brides 38 peuvent être des pièces rapportées et fixées sur le support 3 par soudage ou être obtenues par emboutissage des flasques 31, 32 du support 3.Each of the two
Les deux flasques 71, 72 de la matrice 7 sont montés entre les deux brides 38 de manière à pouvoir être mis en deux positions différentes. Dans la première position, les deux flasques 71, 72 sont espacés l'un de l'autre, ils sont alors en position de coupe. Dans cette position, chacun des deux flasques 71, 72 est engagé dans la découpe 33 du flasque correspondant 31 ou 32 du support 3 et est aligné avec celui-ci. De cette manière, les deux flasques de la matrice sont en même temps empêchés de changer de position. Dans la seconde position, les deux flasques 71, 72 de la matrice 7 sont rapprochés l'un de l'autre afin de pouvoir tourner la matrice 7 vers une autre position, c'est-à-dire lorsqu'une autre des quatre têtes doit être placée en position de coupe.The two
Afin de pouvoir écarter les deux flasques rapidement, lorsque la tête appropriée est mise en position, et afin de pouvoir rapprocher les deux flasques aussi vite lorsqu'il s'agit de mettre une autre tête en position, les deux flasques sont avantageusement, mais non exclusivement, montés sur une broche 8 traversant aussi bien les deux flasques 31, 32 du support 3 que les deux flasques 71, 72 de la matrice 7 et un ressort hélicoïdal 74 disposé entre les deux flasques 71, 72 de la matrice 7. Sur une de ses deux extrémités opposées, la broche 8 est pourvue d'un filetage pour recevoir un écrou moyennant lequel il est possible de régler la longueur effective de la broche. Sur l'autre de ses deux extrémités, la broche est pourvue d'un levier à came 81 moyennant lequel les deux flasques 71, 72 sont rapprochés l'un à l'autre à l'encontre de la contrainte élastique du ressort hélicoïdal 74. Sur une partie centrale de sa longueur, où elle est en contact avec les flasques 71, 72 de la matrice 7, mais avantageusement en dehors des deux parties extrêmes où la broche 8 tourne dans les flasques 31, 32 du support 3, et bien sûr à l'exception de la partie filetée, la broche présente une section transversale hexagonale 82 dont les dimensions correspondent à celles d'un orifice central de chacun des flasques 71, 72 de la matrice 7 destiné à être traversé par la broche 8. Il va sans dire que, selon des variantes de réalisation selon l'invention, la broche 8 et les orifices centraux des flasques 71, 72 peuvent avoir d'autres formes de section transversale, par exemple rectangulaire, notamment carrée, ou triangulaire. En effet, quelle que soit la forme précise polygonale de la section transversale de la broche 8 et des orifices, c'est grâce à elle que la broche et les deux flasques 71, 72 de la matrice 7 sont solidaires en rotation.In order to be able to remove the two flanges quickly, when the appropriate head is put in position, and in order to be able to bring the two flanges as quickly when it comes to put another head in position, the two flanges are advantageously, but no exclusively, mounted on an 8-pin both the
Grâce à cette disposition de l'invention, lorsque le levier de la broche 8 est fait basculer dans une première direction, il n'appuie pas sur le flasque sur lequel il repose. En conséquence, le ressort hélicoïdal produit son effet en écartant les deux flasques. Les deux flasques 71, 72 sont alors situés dans les deux découpes 33 des flasques 31, 32 du support 3 et chacun des deux flasques de la matrice est aligné sur le flasque correspondant du support 3 et les deux flasques 71, 72 forment entre eux la fente 73.With this arrangement of the invention, when the lever of the
En contrepartie, lorsque le levier de la broche 8 est fait basculer vers une seconde direction, opposée à la première, la came du levier appuie sur le flasque et, en comprimant le ressort hélicoïdal, rapproche les deux flasques 71, 72 de la matrice 7. Lorsque l'écrou est bien réglé, les deux flasques 71, 72 viennent alors en contact l'un avec l'autre et, surtout, sortent des découpes 33 des deux flasques 31, 32 du support 3. Dans cette position, la matrice 7 peut être tournée jusqu'à ce qu'une autre tête est devant les découpes 33 des flasques 31, 32 du support 3. Cette position atteinte, le levier de la broche 8 est fait basculer vers la première direction et la matrice 7 se trouve à nouveau en position de travail ou de coupe.In return, when the lever of the

En effet, pour obtenir le résultat escompté de l'invention, c'est-à-dire pour obtenir un outil de coupe permettant de découper des profilés sans les déformer ni former des copeaux longs, le poinçon 211 de la lame 2 est disposé de manière à entrer en premier en contact avec le profilé P à sectionner (voir
Dans l'exemple représenté dans les dessins, le tranchant 24 est pourvu, partant du poinçon 211, d'abord d'un court tronçon concave 212 avant que ne commence le tronçon convexe 213. Ceci est dû au fait que la lame 2 est formée pour être montée pivotante. En conséquence, le poinçon 211 est orienté suivant la tangente T au rayon de pivotement R passant par le centre 261 de l'appendice 26. Un début immédiat du tranchant 24 en forme convexe nuirait à l'efficacité de cisaillement du tranchant. Notons accessoirement que, si la lame 2 était formée pour être montée coulissant entre deux montants du support 3, donc pour fonctionner en translation, le poinçon 211 serait orienté suivant la direction de translation et les deux tranchants pourraient être symétriques l'un par rapport à l'autre et partir de la poinçon 211 en forme convexe sans que cela ne nuise au sectionnement du profilé.In the example shown in the drawings, the
Le choix d'une forme convexe pour les tronçons 213, 215 permet non seulement de sectionner le profilé P, mais permet surtout de pousser les deux copeaux C1, C2 qui se forment, vers la surface intérieure de l'aile correspondante du profilé (voir
Lorsque les deux copeaux C1, C2 ont atteint, chacun indépendamment de l'autre, une longueur suffisante, ils butent contre un tronçon concave 214, 216 qui s'étend à la suite du tronçon convexe 213, 215 correspondant et par lequel les copeaux sont courbés ou enroulés, comme cela est représenté sur les
La réalisation de lame 2 en deux parties, notamment avec une partie 21B comportant le tronçon concave 216, peut contribuer à faciliter la fabrication de la lame, par exemple lorsque les moyens de découpe disponibles pour découper la lame, ne se prêtent pas à obtenir une forme serrée du tranchant 25 comme celle représentée.The embodiment of
Lorsque la découpe du profilé P est terminée, les copeaux C1, C2 sont d'abord maintenus dans deux creux V1, V2 formés par les tronçons concaves 214, 216 qui forment chacun une boucle ayant une étendue correspondant à au moins un demi cercle ou une autre forme courbe comparable, avant d'en être évacués lorsque la lame 2 est pivotée vers sa position ouverte pour accueillir un autre profilé P à sectionner.When the cutting of the profile P is complete, the chips C1, C2 are first held in two recesses V1, V2 formed by the

Selon le mode de réalisation représenté, la lame 202 comporte un corps de lame 221 en deux parties 221A, 221B dont la partie 221B comporte le poinçon 211 et la première partie de chacun de deux tranchants 224, 225 de la lame. Les deux tranchants 224, 225 sont conformés pour sectionner le profilé, à partir d'un point d'impact du poinçon 211 sur le profilé, dans deux directions opposées. Chacun des deux tranchants est pourvu, éloigné du poinçon 211, d'un tronçon concave formant respectivement un creux V1 et un creux V2, dans lesquels creux les copeaux résultant de la découpe sont maintenus avant d'en être évacués lorsque la lame est pivotée vers sa position ouverte.According to the embodiment shown, the
Cependant, il peut arriver que, pour quelle que raison que ce soit, le copeau maintenu dans le petit creux V1 en sort déjà lorsque la lame n'est pas encore suffisamment relevée pour que le copeau puisse tomber à côté de l'outil et qu'il reste coincé entre les deux flasques 31, 32 du support 3.However, it may happen that, for whatever reason, the chip held in the small hollow V1 comes out already when the blade is not yet sufficiently raised so that the chip can fall next to the tool and that it remains stuck between the two
Dans une telle situation, le doigt éjecteur 29 qui est formé en une seule pièce avec le corps de la lame 21 et dont l'extrémité libre est avantageusement, mais non nécessairement, coudée approximativement en direction de la pointe 211, relève le copeau et l'éjecte de l'outil.In such a situation, the

Selon ce qui est indiqué par une ligne interrompue S, la lame 302 peut être réalisée soit en une seule partie, soit en deux parties. Dans le dernier cas, la partie 321B est réalisée avantageusement en un matériau plus dur que la partie 321A.According to what is indicated by a broken line S, the
