Abstract
The cutting out pliers have a punch and a die on the jaws (7,9) and also a vessel (14) fixed below the die, and into which the latter opens. The vessel can be a transparent tube joined to the die on one side, and closed by a detachable plug at one end. The die can be a stepped component (10) on the pliers, while a screw (11) secures it to them and also the tube in a recess in it. The die can have a flat surface at the front, and a rear edge (16) forming a stop for a plate or strip to be cut out. ADVANTAGE - Particularly for the manufacture of jewellery, there being no risk of loss of offcuts of precious metal.
Description
La présente invention a pour objet une pince à découper, en particulier pour la bijouterie.
En bijouterie, il est très souvent nécessaire de découper de petits morceaux de métal noble, tel que de l'or ou du platine, pour effectuer des soudures. Lors de la coupe d'un bout de fil, de bande ou de plaque au moyen d'une pince coupante usuelle, le morceau coupé a tendance à être projeté, ce qui entraîne souvent sa perte, compte tenu des faibles dimensions du morceau coupé.
La présente invention a pour but d'éliminer tout risque de perte du petit morceau découpé au moyen d'une pince.
A cet effet, la pince selon l'invention est caractérisée par le fait que ses mâchoires sont munies respectivement d'un poinçon et d'une matrice, ainsi que d'un réceptacle fixé à la pince, sous la matrice, et dans lequel débouche la matrice.
Ainsi, le petit morceau découpé par le poinçon et la matrice tombe dans le réceptacle où il peut être facilement récupéré. La pince selon l'invention offre en outre l'avantage de permettre de découper plusieurs morceaux à la suite, ces morceaux restant stockés dans le réceptacle pour être utilisés ultérieurement. L'artisan peut ainsi travailler plus rationnellement.
Le dessin annexé représente, à titre d'exemple, une forme d'exécution de l'invention.
La fig. 1 est une vue de dessous des mâchoires d'une pince à découper.
La fig. 2 est une vue de côté de ces mêmes mâchoires.
La fig. 3 est une vue de dessus de ces mâchoires.
La pince est constituée de deux branches 1 et 2 partiellement représentées maintenues écartées l'une de l'autre par deux ressorts lames 3 et 4 respectivement solidaires des branches 1 et 2 et dont les extrémités s'appuyent l'une contre l'autre. Les branches 1 et 2 sont articulées autour d'un axe constitué d'une vis 5 et d'un écrou 6. La mâchoire 7 de la branche 1 est munie d'un poinçon 8. La mâchoire 9 de la branche 2 est prolongée en avant relativement à la mâchoire 7 et elle porte une matrice 10 fixée sur le mâchoire 9 au moyen d'un vis 11 et dont la découpe 12 coopère avec le poinçon 8. Le corps de la matrice 10 présente un profil en U dont les ailes 12 et 13 s'étendent de chaque côté de la mâchoire 9 et présentent des faces intérieures concaves cylindriques.
Entre ces faces concaves 12 et 13 est logé un tube 14 en matière plastique transparente dont le diamètre est sensiblement égal au diamètre du cylindre limité par les faces intérieures des ailes 12 et 13 et dont le côté supérieur est fraisé de façon à présenter un méplat collé contre la face supérieure de la mâchoire 9. Le tube 14 est fermé par un bouchon 15 vissé dans le tube. Le corps la matrice 10 présente en outre à l'arrière un rebord 16 servant de butée pour la plaquette ou la bande à découper. On appuie celle-ci contre la butée 16, actionne la pince et le petit morceau découpé tombe dans le tube transparent 14.
La matrice 10 étant amovible, il est possible de la remplacer par une matrice d'une autre forme pour obtenir des découpes de formes différentes.
Le tube pourrait être fixé par la vis 11. Il pourrait être remplacé par un réceptacle de tout autre forme et d'autres dimensions.
La pince pourrait bien entendu être d'un autre type, par exemple à mâchoires articulées sur les branches et à deux axes, comme certaines pinces coupantes.
The present invention relates to a cutting pliers, in particular for jewelry.
In jewelry, it is very often necessary to cut small pieces of noble metal, such as gold or platinum, to perform welding. When cutting a piece of wire, strip or plate using conventional cutting pliers, the cut piece tends to be thrown, which often results in its loss, given the small dimensions of the cut piece.
The present invention aims to eliminate any risk of loss of the small piece cut by means of pliers.
To this end, the clamp according to the invention is characterized in that its jaws are provided respectively with a punch and a matrix, as well as a receptacle fixed to the clamp, under the matrix, and into which opens the matrix.
Thus, the small piece cut by the punch and the die falls into the receptacle where it can be easily recovered. The pliers according to the invention also offers the advantage of making it possible to cut several pieces in succession, these pieces remaining stored in the receptacle for later use. The craftsman can thus work more rationally.
The accompanying drawing shows, by way of example, an embodiment of the invention.
Fig. 1 is a bottom view of the jaws of a cutting pliers.
Fig. 2 is a side view of these same jaws.
Fig. 3 is a top view of these jaws.
The clamp consists of two branches 1 and 2 partially shown kept apart from one another by two leaf springs 3 and 4 respectively secured to the branches 1 and 2 and the ends of which bear against one another. The branches 1 and 2 are articulated around an axis consisting of a screw 5 and a nut 6. The jaw 7 of the branch 1 is provided with a punch 8. The jaw 9 of the branch 2 is extended by front relative to the jaw 7 and it carries a matrix 10 fixed to the jaw 9 by means of a screw 11 and the cutout 12 of which cooperates with the punch 8. The body of the matrix 10 has a U-shaped profile whose wings 12 and 13 extend on each side of the jaw 9 and have concave cylindrical inner faces.
Between these concave faces 12 and 13 is housed a tube 14 made of transparent plastic whose diameter is substantially equal to the diameter of the cylinder limited by the inner faces of the wings 12 and 13 and whose upper side is milled so as to have a glued flat against the upper face of the jaw 9. The tube 14 is closed by a plug 15 screwed into the tube. The body of the matrix 10 also has at the rear a flange 16 serving as a stop for the wafer or the strip to be cut. This is pressed against the stop 16, actuates the clamp and the small cut piece falls into the transparent tube 14.
The matrix 10 being removable, it is possible to replace it with a matrix of another shape to obtain cuts of different shapes.
The tube could be fixed by the screw 11. It could be replaced by a receptacle of any other shape and other dimensions.
The pliers could of course be of another type, for example with jaws articulated on the branches and with two axes, like certain cutting pliers.
