Description
L'invention est relative aux coupe boulons composés, comme montré figure 1 annexée :
- d'une tête A avec lames 2, entretoises 3 et axes 4 pour les lames,
- de bras de manoeuvre B1, B2,
- et de moyens C, multiplicateurs d'effort de coupe.
- a head A with blades 2, spacers 3 and pins 4 for the blades,
- of operating arms B1, B2,
- and of means C, cutting force multipliers.
Dans les coupes boulons actuels, ces moyens C comprennent des
axes 5 et 6a, 6b, qui, parallèles aux axes 4 d'articulation des lames, coopèrent
avec des chapes et tenons réalisés dans des parties forgées à l'extrémité des
bras (voir par exemple DE 29821378U).In current bolt cutters, these means C include
Ce mode de réalisation est coûteux, car mettant en oeuvre des moyens importants pour assurer le forgeage à chaud et nécessitant des reprises d'usinage.This embodiment is costly, since implementing important means for ensuring hot forging and requiring machining resumptions.
La présente invention vise à remédier à ces inconvénients en fournissant un coupe boulon qui, ayant un coût de fabrication réduit, est plus résistant.The present invention aims to remedy these drawbacks by providing a bolt cutter which, having a reduced manufacturing cost, is more resistant.
A cet effet, dans le coupe boulon selon l'invention, chacun des bras est constitué par un tube métallique dont l'extrémité antérieure écrasée contient, par emmanchement serré, deux tenons faisant partie de deux pièces métalliques issues d'un même flan découpé, embouti et traité, pour former l'un des deux éléments d'articulation des bras, respectivement femelle et mâle, chaque pièce comportant deux branches antérieures formant, dans l'élément d'articulation femelle, deux chapes coopérant, celle intérieure, à l'articulation des bras, celle extérieure à l'articulation d'une lame, et, dans l'élément d'articulation mâle, une chape extérieure coopérant avec une lame et un tenon intérieur pénétrant dans la chape intérieure de l'élément femelle pour l'articulation des bras.To this end, in the bolt cutter according to the invention, each of the arms consists of a metal tube whose crushed front end contains, by tight fitting, two tenons forming part of two parts metallic from the same blank cut, stamped and treated, to form one of the two articulation elements of the arms, female and male respectively, each part comprising two anterior branches forming, in the element of female articulation, two clevis cooperating, the inner one, at the articulation arms, the one outside the hinge of a blade, and, in the element of male articulation, an external clevis cooperating with a blade and a tenon interior penetrating into the inner yoke of the female element for the articulation of the arms.
En raison de la réalisation par découpage et emboutissage d'une tôle métallique, conformée à la demande et traitée ultérieurement, les moyens multiplicateurs d'efforts disposés à l'extrémité antérieure des bras peuvent présenter une résistance bien supérieure à celle obtenue jusqu'alors par l'extrémité antérieure usinée des bras forgés traditionnels et cela pour un coût de fabrication moindre.Due to the production by cutting and stamping of a sheet metal, conforming to the request and further processed, the means force multipliers arranged at the anterior end of the arms can have a resistance much higher than that hitherto obtained by the machined anterior end of traditional forged arms at a cost less manufacturing.
Dans une forme d'exécution de ce coupe boulons, les deux branches de chacune des pièces métalliques formant dans l'élément d'articulation mâle, respectivement le tenon et la chape, sont séparées par une fente longitudinale qui s'étend jusqu'à un perçage de libération des contraintes traversant l'épaisseur de ces deux pièces, et au moins l'une de ces branches comporte, dans son bord intérieur, une découpe de positionnement et d'appui d'un écrou carré pour une vis d'écartement, se vissant dans l'écrou, passant entre les deux ailes de la chape et venant en appui sur le bord intérieur du tenon.In one embodiment of this bolt cutter, both branches of each of the metal parts forming in the element of male articulation, respectively the tenon and the clevis, are separated by a longitudinal slot extending to a stress relief hole crossing the thickness of these two parts, and at least one of these branches has, in its inner edge, a positioning and support cutout a square nut for a spacer screw, screwing into the nut, passing between the two wings of the yoke and coming to rest on the inner edge of the tenon.
Cet aménagement permet pour un faible surcoût de fabrication d'intégrer dans l'élément d'articulation mâle des moyens permettant de modifier l'écartement entre les deux branches de ces deux pièces métalliques et, en conséquence, de modifier l'écartement entre l'axe d'articulation d'une lame et l'axe d'articulation des bras, pour ajuster l'entrefer entre les deux parties tranchantes des lames. Ce dispositif simple remplace avantageusement le réglage par excentrique disposé entre l'axe d'articulation des bras et le logement recevant cet axe, puisqu'il permet d'obtenir une plus grande course de réglage.This arrangement allows for a low manufacturing cost to integrate into the male articulation element means making it possible to modify the spacing between the two branches of these two metal parts and, in consequently, to modify the spacing between the hinge axis of a blade and the articulation axis of the arms, to adjust the air gap between the two parts sharp blades. This simple device advantageously replaces the eccentric adjustment disposed between the articulation axis of the arms and the housing receiving this axis, since it makes it possible to obtain a greater stroke adjustment.
L'invention concerne également le procédé de fabrication du coupe boulon.The invention also relates to the method of manufacturing the cup. bolt.
Ce procédé consiste :
- à découper dans une tôle d'acier des ébauches identiques comportant un tenon postérieur et deux branches antérieures ;
- à former la paire de pièces de l'élément mâle, en réalisant, par cisaillage, une fente entre les deux branches de ces pièces et en conformant chaque pièce par déformation vers l'extérieur de la branche extérieure pour former une chape ;
- à former la paire de pièces de l'élément mâle en déformant à la presse l'extrémité antérieure de chacune de ces pièces, de manière que les deux branches soient décalées transversalement par rapport au talon, mais en sens inverse pour former deux chapes ;
- à réunir les pièces de chaque paire par juxtaposition de leurs talons
- et à assurer la liaison de chaque élément d'articulation mâle ou femelle par emmanchement serré des talons de chaque paire de pièces dans l'extrémité antérieure écrasée d'un tube métallique.
- cutting from a steel sheet identical blanks comprising a rear post and two front branches;
- forming the pair of parts of the male element, by making, by shearing, a slit between the two branches of these parts and by shaping each part by deformation towards the outside of the external branch to form a yoke;
- forming the pair of parts of the male element by deforming with the press the anterior end of each of these parts, so that the two branches are offset transversely relative to the heel, but in the opposite direction to form two yokes;
- to join the pieces of each pair by juxtaposition of their heels
- and ensuring the connection of each male or female articulation element by tight fitting of the heels of each pair of parts in the crushed anterior end of a metal tube.
Ce procédé de fabrication est moins onéreux que celui actuel, nécessitant forgeage et usinage, puisque les ébauches, découpées et conformées par emboutissage, ne nécessitent aucune reprise d'usinage. Le remplacement du forgeage par un découpage d'ébauches permet d'utiliser des matières, et en particulier des aciers, supportant ultérieurement des traitements thermiques améliorant leurs caractéristiques physiques et la résistance du coupe boulon. En outre le délai pour le lancement de fabrication, de même que la durée de fabrication sont plus courts que ceux nécessaires pour la fabrication de bras forgés et usinés.This manufacturing process is less expensive than the current one, requiring forging and machining, since the blanks, cut and shaped by stamping, do not require any further machining. The replacing forging by cutting blanks allows the use of materials, and in particular steels, which subsequently undergo treatments thermal improving their physical characteristics and the resistance of bolt cutter. In addition, the time for launching production, as well as manufacturing times are shorter than those required for the manufacture of forged and machined arms.
