Abstract

The invention relates to a universal punching tool. The one-piece mechanism of the universal tool, with its plunging striking head 1 and its punch holder 2 to which the short punches 3 are attached, receives the guide 4 fitted with its plate (sheet) grip 5. This universal tool, with its plunging striking head to which the punch holder is attached, can receive short punches as well as the corresponding plate grips whose particular design allows simple and effective attachment to the guide. This design of the tool avoids the use of a specific assembly for each punch and, in addition, allows the punch to be sharpened over a length of 10 mm. This results in an obvious saving as regards the duration of use of the punch. The application of these tools is particularly advantageous on punching machines having turrets.

Description

La présente invention concerne les outils de poinçonnage pour métaux par découpage de ceux-ci. Ces outils sont utilisés sur des poinçonneuses a tourelles revolver à postes multiples ou uniques.The present invention relates to punching tools for metals by cutting them. These tools are used on punching machines with revolver turrets with multiple or single stations.

Les outils connus à ce jour se présentent sous la forme d'un ensemble se composant d'un poinçon long traversant de part en part l'ensemble du mécanisme, d'un guide poinçon dont la base épouse la forme du poinçon et faisant office de dévAtisseur, d'un ressort de dévêtissage, d'un écrou de frappe, d'une rondelle de retenue et de visserie diverse. Sur ce type d'outil, un changement de poinçon entraîne systématiquement le remplacement de l'ensemble de l'outil. D'où son coût élevé. De surcroît, et compte tenue de la hauteur trés limitée de l'écrou de frappe auquel est fixé le poinçon, la longueur d'affûtage de ce dernier est limitée à 2 m/m. A noter également que le guide poinçon en acier qui est en même temps le serre-tôle a l'inconvénient de rayer les métaux.L'outil selon l'invention permet d'éviter un tel ensemble propre à chaque poinçon. Les résultats visés sont 1) De remplacer l'ensemble de l'outil propre à chaque poinçon par un mécanisme monobloc universel pouvant recevoir des poinçons courts de sorte que seul le poinçon et son serre-tôle, qui se présente sous la forme d'une rondelle fendue, sont à changer.The tools known to date are in the form of an assembly consisting of a long punch passing right through the entire mechanism, a punch guide whose base matches the shape of the punch and acting as deviator, a stripping spring, a striking nut, a retaining washer and various screws. On this type of tool, a change of punch systematically results in the replacement of the entire tool. Hence its high cost. In addition, and taking into account the very limited height of the impact nut to which the punch is fixed, the sharpening length of the latter is limited to 2 m / m. Note also that the steel punch guide which is at the same time the sheet clamp has the disadvantage of scratching the metals. The tool according to the invention makes it possible to avoid such an assembly specific to each punch. The targeted results are 1) To replace the entire tool specific to each punch by a universal monobloc mechanism that can receive short punches so that only the punch and its sheet clamp, which is in the form of a split washer, are to be changed.

2) De disposer, grâce à la tête de frappe plongeante, d'une grande longueur de filetage pour la fixation du porte-poinçon, et permettre de ce fait, de porter la longueur d'affûtage du poinçon de 2 à 10 m/m.2) Having, thanks to the plunging impact head, a large length of thread for fixing the punch holder, and thereby allowing the sharpening length of the punch to be increased from 2 to 10 m / m .

3) De pouvoir remplacer le poinçon sans avoir à démonter et à remonter le mécanisme monobloc.3) To be able to replace the punch without having to disassemble and reassemble the one-piece mechanism.

4) D'avoir un guide poinçon universel auquel se fixe le serre-tôle en matière composite qui se présente sous la forme d'une rondelle fendue. Ce serre-tôle a d'autre part l'avantage de ne plus rayer les métaux et se fixe par une simple pression sur le guide. La conception particulière de ce serre-tôle, du fait qu'il soit fendu, agit comme un ressort lors de sa mise en place, et une fois en place autour du poinçon, il devient inamovible. Pour le retirer il y a lieu de retirer en premier le guide qui est simplement tenu par un jonc.4) To have a universal punch guide to which the composite sheet clamp is fixed, which is in the form of a split washer. This sheet clamp also has the advantage of no longer scratching the metals and is fixed by a simple pressure on the guide. The particular design of this sheet clamp, due to the fact that it is split, acts as a spring when it is put in place, and once in place around the punch, it becomes irremovable. To remove it, first remove the guide, which is simply held by a ring.

5) D'empêcher lors de l'action, le dévissage du porte-poinçon grâce aux deux bagues en caoutchouc fixées sur la queue du porte-poinçon et qui s'insèrent entre le porte-poinçon et la tête de frappe.5) To prevent during the action, the unscrewing of the punch holder thanks to the two rubber rings fixed on the tail of the punch holder and which are inserted between the punch holder and the striking head.

6) D'avoir un outil de hauteur toujours constante, même aprés affûtage du poinçon. 6) To have a tool of always constant height, even after sharpening the punch.

7) D'être plus économique du fait que seuls le poinçon et le serre-tôle sont à changer, et non plus ltensemble de l'outil. A cela il faut ajouter que la durée d'utilisation du poinçon est à multiplier par cinq, du fait que la hauteur d'affûtage passe de 2 à 10 m/m.7) To be more economical since only the punch and the sheet clamp are to be changed, and no longer the whole tool. To this must be added that the duration of use of the punch is to be multiplied by five, because the sharpening height goes from 2 to 10 m / m.

Le dessin annexé représente une vue en coupe de l'outil avec son mécanisme monobloc universel.The accompanying drawing shows a sectional view of the tool with its universal one-piece mechanism.

Le mécanisme monobloc de l'outil universel constitué d'une tête de frappe plongeante 1, de son ressort de dévêtissage 2, de sa bague de retenue 3, et de sa bague d'arrêt 4, reçoit le porte-poinçon 5, muni de deux bagues de freinage en caoutchouc 6, le poinçon court 7,indexé en cas de forme par la goupille 8, et maintenu sur la périphérie par trois vis à bout sphérique en acier trempé 9, ainsi que le guide-poinçon 10, qui se fixe par une simple poussée vers le haut sur la bagué de retenue 3, équipée du jonc 12. Le serre-tôle interchangeable 11, de par sa conception particulière, du fait qu'il soit fendu, se fixe instantanés ment sur le guide par une légère pression latérale.The one-piece mechanism of the universal tool consisting of a plunging head 1, its stripping spring 2, its retaining ring 3, and its stop ring 4, receives the punch holder 5, provided with two rubber brake rings 6, the short punch 7, indexed in the case of form by the pin 8, and held on the periphery by three ball point screws in hardened steel 9, as well as the punch guide 10, which is fixed by a simple push upwards on the retaining ring 3, fitted with the rod 12. The interchangeable sheet clamp 11, by virtue of its particular design, owing to the fact that it is split, is instantaneously fixed on the guide by a slight lateral pressure.

Les possibilités d'application de ces outils sont, compte tenu de leur universalite et de l'interchangeabilité des poincons et serre-tôles avec possibilité d'affûter les poinçons sur 10 m/m , trés appréciées par les utilisateurs de ces machines.  The possibilities of application of these tools are, given their universality and the interchangeability of the punches and sheet clamps with the possibility of sharpening the punches on 10 m / m, very appreciated by the users of these machines.
