Abstract
Description
L'invention concerne les lames de coupe notamment circulaire ou rubanThe invention relates to particularly circular or ribbon cutting blades
notamment pour les métaux pour des machines-outils. - especially for metals for machine tools. -
Dans les lames classiques, on rencontre des problèmes de propreté de coupe notamment avec des bavures notamment sur l'acier ou l'acier-inox. In conventional blades, problems of cleanliness of cutting are encountered, in particular with burrs, in particular on steel or stainless steel.
L'invention vise à remédier à ces inconvénients en éliminant ou en limitant notablement le phénomène d'apparition de bavures. The invention aims to remedy these drawbacks by eliminating or notably limiting the phenomenon of appearance of burrs.
io La lame est notamment prévue pour couper des tôles de type sandwich avec isolant d'épaisseur, l'épaisseur totale étant par exemple de 20mm à 200mm. io The blade is in particular provided for cutting sandwich type sheets with thickness insulation, the total thickness being for example from 20 mm to 200 mm.
L'invention concerne une lame de scie remarquable en ce qu'elle comprend une suite répétitive d'un train de dents successives différentes composé: - d'une première dent haute d'ébauche, - puis d'une seconde dent basse de finition, - puis d'une troisième dent basse de finition, les seconde et troisième dents ayant une conformation identique The invention relates to a remarkable saw blade in that it comprises a repetitive series of a train of successive different teeth composed: - of a first high roughing tooth, - then of a second low finishing tooth, - then a third lower finishing tooth, the second and third teeth having an identical conformation
d'afftage latérale alternée d'un côté puis de l'autre. side trim alternately on one side then on the other.
Selon des modes particuliers de réalisation: - la première dent est afftée sur la partie supérieure de la dent According to particular embodiments: - the first tooth is affté on the upper part of the tooth
symétriquement de type Heller.symmetrically of the Heller type.
- les seconde et troisième dents sont en afftage alternées sur la partie supérieure de chaque dent latéralement d'un côté puis de l'autre. - The second and third teeth are alternately sharpened on the upper part of each tooth laterally on one side then on the other.
- le premier angle d'afftage a de la première dent est compris dans un intervalle de 10 à 550 par rapport au plan horizontal supérieur tel que représenté figure 1. - The first sharpening angle a of the first tooth is in the range from 10 to 550 relative to the upper horizontal plane as shown in FIG. 1.
- les angles d'afftage alternés des seconde et troisième dents sont un 35 second angle f compris dans un intervalle de 1 à 25 et un troisième angle Y compris dans un intervalle de 1 à 55 par rapport au plan horizontal supérieur tel que représenté figures 2 et 3. - the alternate sharpening angles of the second and third teeth are a second angle f included in the range from 1 to 25 and a third angle Y included in the interval from 1 to 55 relative to the upper horizontal plane as shown in FIGS. 2 and 3.
- la première dent comprend une partie supérieure plate d'épaisseur A - the first tooth comprises a flat upper part of thickness A
représentant 1/10 à 4/5 de la largeur de la dent tel que représenté figure 1. representing 1/10 to 4/5 of the width of the tooth as shown in Figure 1.
- les seconde et troisième dents comprennent chacune uene partie supérieure pointue à sommets alternés décalés avec une largeur B de chanfrein pour l'inclinaison du troisième angle y comprise entre 0.05 à 1 nmm tel que représenté figures 2 et 3. - tout ou partie des première, seconde et troisième dents présente sur la partie supérieure une partie de face frontale inclinée d'angle fl par rapport à la verticale, variant de 0 à 200 positif ou de 0 à 250 négatif - The second and third teeth each comprise a pointed upper part with alternating vertices offset with a width B of chamfer for the inclination of the third angle therein between 0.05 to 1 nmm as shown in Figures 2 and 3. - all or part of the first , second and third teeth present on the upper part a front face part inclined at an angle fl relative to the vertical, varying from 0 to 200 positive or from 0 to 250 negative
tel que représenté figure 4 avec un angle négatif. as shown in Figure 4 with a negative angle.
- toute ou partie des première, seconde et troisième dents est constitué sur leur partie frontale d'un élément de lame rapporté notamment en carbure avant afftage tel que représenté figure 6 avec un angle ú - all or part of the first, second and third teeth is formed on their front part of a blade element reported in particular in carbide before sharpening as shown in Figure 6 with an angle ú
