Abstract
Description
La présente invention concerne un dispositif pour la fixation de poinçons et autres éléments dans les outils de découpage, emboutissage, cambrage et autres outils de presses.The present invention relates to a device for fixing punches and other elements in cutting tools, stamping, bending and other press tools.
L'invention s'applique principalement aux poinçons de petites dimensions, de forme simple ou complexe dont la section active où la matière ne permet pas l'implantation d'une vis de diamètre suffisant pour en assurer leur maintien.The invention applies mainly to punches of small dimensions, of simple or complex shape whose active section where the material does not allow the implantation of a screw of sufficient diameter to ensure their maintenance.
Ces poinçons sont généralemment retenus en donnant à leur extrêmité non active une section plus importante. Cette solution présente souvent des démontages peu pratiques et surtout des difficultés de fabrication, notamment avec les machines "électro-érosion à fil". Elle oblige le cas échéant la confection de poinçons symétriques dits "à droite et à gauche".These punches are generally retained by giving their non-active end a larger section. This solution often presents impractical dismantling and above all manufacturing difficulties, in particular with "wire EDM" machines. It obliges if necessary the confection of symmetrical punches known as "on the right and on the left".
Le dispositif, selon l'invention, permet de remédier à ces inconvénients. Il est particulièrement adapté pour fixer des éléments tels que poinçons dans leur logement de positionnement que possède leur plaque-support. Il comporte un ensemble de deux coins complémentaires formant un parallélépipède droit contenu dans un logement voisin de celui de l'élément à fixer, un des coins comporte au moins un trou apte à recevoir une vis propre à l'entraîner, de sorte à faire augmenter la cote d'empilage des deux coins, provoquant ainsi le blocage par pincement de l'élément à fixer.The device according to the invention overcomes these drawbacks. It is particularly suitable for fixing elements such as punches in their positioning housing which their support plate has. It comprises a set of two complementary corners forming a straight parallelepiped contained in a housing close to that of the element to be fixed, one of the corners comprises at least one hole capable of receiving a screw capable of driving it, so as to increase the stacking dimension of the two corners, thus causing the element to be fixed to be pinched.
Selon une réalisation préférentielle, le deuxième coin dit fixe est remplacé par une partie de l'élément support avant la même forme et remplissant la même fonction.According to a preferred embodiment, the second so-called fixed corner is replaced by a part of the support element before the same shape and fulfilling the same function.
La figure 1 représente une vue éclatée du dispositif selon l'invention sur une vue partielle d'un bloc support (7).FIG. 1 represents an exploded view of the device according to the invention on a partial view of a support block (7).
La figure 2 représente en coupe le dispositif monté dans un porte-poinçons.Figure 2 shows in section the device mounted in a punch holder.
Les figures suivantes représentent des variantes du dispositif.The following figures show variants of the device.
Le dispositif représenté sur les figures 1 et 2 est contenu dans un logement (b) de la plaque support (6) voisin du logement (a) contenant l'élément à fixer (4). Il comprend un ensemble de deux coins complémentaires (1 et 2) formant un parallélépipède droit et au moins une vis (5) qui traverse et entraîne le coin mobile (1) pour le faire glisser suivant son plan incliné sur le coin fixe (2), la face du coin en appui sur l'élément à fixer (4) épousant sa surface de contact, et n'exigeant en aucun cas de cet élément une section différente de celle de sa partie active (c).The device shown in Figures 1 and 2 is contained in a housing (b) of the support plate (6) adjacent to the housing (a) containing the element to be fixed (4). It includes a set of two complementary corners (1 and 2) forming a straight parallelepiped and at least one screw (5) which crosses and drives the movable corner (1) to slide it along its inclined plane on the fixed corner (2) , the face of the wedge resting on the element to be fixed (4) conforming to its contact surface, and in no case requiring this element a section different from that of its active part (c).
Le déplacement du coin mobile (1) fait croître la cote d'empilage des deux coins provoquant ainsi par pincement le blocage de l'élément (4) dans son logement (a). La vis (5) est vissée dans le bloc support (7). Le faible déplacement du coin (1) vers l'élément à fixer (4) est permis par le jeu de la vis dans son passage.The displacement of the movable corner (1) increases the stacking dimension of the two corners, thus pinching the blocking of the element (4) in its housing (a). The screw (5) is screwed into the support block (7). The slight displacement of the corner (1) towards the element to be fixed (4) is allowed by the play of the screw in its passage.
Les coins (1 et 2) sont généralement réalisés dans une matière similaire à la plaque support (6).The corners (1 and 2) are generally made of a material similar to the support plate (6).
Le nombre de vis (5) et ses dimensions, ainsi que les dimensions des coins (1 et 2) sont déterminés suivant les caractéristiques de l'élément à fixer (4).The number of screws (5) and its dimensions, as well as the dimensions of the corners (1 and 2) are determined according to the characteristics of the element to be fixed (4).
La figure 73 représente en coupe une variante du dispositif où le coin fixe (2) est remplacé par une partie de la plaque support (6) ayant la même forme et remplissant la même fonction. Cette même figure représente une autre variante où la vis (5) traverse librement le bloc support (7) et se visse dans le coin mobile (1).Figure 73 shows in section a variant of the device where the fixed corner (2) is replaced by a part of the support plate (6) having the same shape and fulfilling the same function. This same figure represents another variant where the screw (5) freely crosses the support block (7) and is screwed into the movable corner (1).
Les figures 4, 5, 6 et 7 représentent des exemples où un seul dispositif est adapté pour fixer plusieurs poinçons (4) relativement proches les uns des autres en coopérant avec d'éventuelles cales intermédiaires (8) sur les figures 6 et 7, ou en ayant une forme spéciale suivant les figures 4 et 5. Le coin mobile (1) sur ces dernières comporte alors deux faces d'appui en contact avec les poinçons (4), ces deux faces d'appui et sa face oblique ainsi que celle de l'éventuel coin fixe (2) sont contenues dans des plans formant un tétraèdre. Le déplacement du coin (1) vers le fond du logement provoque alors une poussée simultanée sur sa face oblique et sur les deux faces en contact avec les poinçons (4).Figures 4, 5, 6 and 7 show examples where a single device is suitable for fixing several punches (4) relatively close to each other by cooperating with possible intermediate shims (8) in Figures 6 and 7, or having a special shape according to Figures 4 and 5. The movable corner (1) on the latter then has two bearing faces in contact with the punches (4), these two bearing faces and its oblique face as well as that of the possible fixed corner (2) are contained in planes forming a tetrahedron. The displacement of the corner (1) towards the bottom of the housing then causes a simultaneous push on its face oblique and on both sides in contact with the punches (4).
Selon les figures 8 et 9, le dispositif suivant les différentes variantes précédemment décrites est apte à être monté en groupe pour fixer un seul et même poinçon ou élément. Ces mêmes figures illustrent une variante de la vis (5) qui est une vis sans tête à deux filetages dont les pas sont différents. Ce genre de vis multiplie l'effort de serrage et permet un déblocage facile du dispositif.According to Figures 8 and 9, the device according to the different variants described above is adapted to be mounted in a group to fix a single punch or element. These same figures illustrate a variant of the screw (5) which is a headless screw with two threads whose pitch is different. This kind of screw multiplies the tightening effort and allows an easy release of the device.
Les figures 5 et 7 représentent également deux exemples où le coin mobile (1) est entraîné dans le sens desserrage, en plus du sens serrage, par la vis (5) dont la tête est prisonnière, par une plaquette (10) figure 5, par une goupille (9) figure 7, ou tout autre accessoire apte à donner un appui au-dessus de la tête de la vis (5) afin que son dévissage repousse le coin (1) et libère le ou les poinçons (4).FIGS. 5 and 7 also show two examples where the movable wedge (1) is driven in the loosening direction, in addition to the tightening direction, by the screw (5) whose head is trapped, by a plate (10) in FIG. 5, by a pin (9) Figure 7, or any other accessory capable of giving a support above the head of the screw (5) so that its unscrewing pushes the corner (1) and releases the punch (s) (4).
La figure 10 est une vue en perspective d'un bloc matrice de découpe à éléments rapportés, elle représente un exemple d'application du dispositif selon l'invention, adapté pour remplacer avantageusement les traditionnelles clés. Les éléments (4') situés aux extrêmités du bloc support (7') portent des logements ou encoches correspondant aux quatre encoches du bloc (7') recevant habituellement les clés. Deux de ces encoches d'une même extrêmité du bloc 7' reçoivent des taquets fixes (11), les deux autres reçoivent des taquets (12) dits réglables, portant un dispositif suivant l'invention.Figure 10 is a perspective view of a die cutting block with added elements, it shows an example of application of the device according to the invention, adapted to advantageously replace the traditional keys. The elements (4 ') located at the ends of the support block (7') carry housings or notches corresponding to the four notches of the block (7 ') usually receiving the keys. Two of these notches at the same end of the block 7 'receive fixed lugs (11), the other two receive lugs (12) said to be adjustable, carrying a device according to the invention.
La figure 11 illustre cette même variante, en représentant le dispositif, en vue de face, contenu dans le décrochement d'un taquet de positionnement (12), lui-même contenu en partie dans une encoche d'un élément à fixer (4') et comprenant un coin mobile (1) entraîné par une vis (5) traversant le taquet (12) qui comporte une partie apte à remplacer le coin fixe (2) des figures (1 et 2).FIG. 11 illustrates this same variant, by representing the device, in front view, contained in the recess of a positioning cleat (12), itself partly contained in a notch of an element to be fixed (4 ' ) and comprising a movable corner (1) driven by a screw (5) passing through the cleat (12) which comprises a part capable of replacing the fixed corner (2) of the figures (1 and 2).
La figure 12 représente une autre variante du dispositif selon l'invention applicable également à la fixation d'éléments juxtaposés dans un bloc support (7'). Il varie par le fait que le coin mobile est intégré au taquet (12') et coopère avec une partie inclinée que possède l'élément à fixer (4') la vis (5) sans tête prend alors appui sur l'élément (4') de sorte à entraîner le taquet (12') qui coulisse dans l'encoche du bloc (7') et provoque alors le pincement des éléments (4') contre les taquets (11) de la figure 10.FIG. 12 represents another variant of the device according to the invention also applicable to the fixing of juxtaposed elements in a support block (7 ′). It varies by the fact that the movable corner is integrated into the cleat (12 ') and cooperates with an inclined part which has the element to be fixed (4') the screw (5) without head then bears on the element (4 ') so as to drive the cleat (12') which slides in the notch of the block (7 ') and then causes the elements (4') to be pinched against the tabs (11) of FIG. 10.
Les variantes du dispositif illustrées par les figures 10-11-12 sont principalement adaptées aux éléments tels que matrices, celles-ci devant éventuellement recevoir une cale (13) pour compenser l'affûtage.The variants of the device illustrated in FIGS. 10-11-12 are mainly adapted to elements such as dies, these possibly having to receive a shim (13) to compensate for the sharpening.
L'invention n'est pas limitée aux seules formes de réalisations et applications décrites ci-dessus mais engloble toutes les variantes et modifications issues du même principe de base.The invention is not limited to only the embodiments and applications described above but encompasses all the variants and modifications resulting from the same basic principle.
Les différents dispositifs présentés dans ce descriptif sont aptes à être commercialisés en éléments standard.The various devices presented in this description are suitable for being sold as standard elements.
