Abstract

The adjustable band saw consisting of a base frame (15) provided with two bearings (11,11') for forming a pivot with the cutter. This contains two slides (5,5') made up of cylindrical ends in which the support (4) for the wheels slides. The support is controlled in movement by hydraulic jacks (6,6') which supports the two wheels (3,3'), one of which is motor driven (1) to drive the cutting band (2). The orientation of the cut is by a worm and wheel drive (7,8) attached to the cylindrical part of the slide and having, on the other end, a graduated drum (9) and a hand wheel (10). The whole being locked by stops (12,12'). A slide (13) is fitted to the base (15), on which is fixed the work piece (20), that can move longitudinally to and from the cutting blade (2) when driven by an electric motor (14).

Description

DESCRIPTIONDESCRIPTION

L'intervention concerne une machine de sciage réglable à ruban qui comporte un bâti (15) muni de deux paliers ( 1,1 1') pour réaliser une liaison pivot avec l'ensemble formant le système de coupe qui est constitué de deux glissièreas (5,5') comportant des extrémités cylindriques; dans laquelle glisse un support de volant (4) qui est contrôlé en translation par deux verins hydrauliques (6,6') et qui supporte deux volants (3,3') dont l'une est liée au moteur  The intervention concerns an adjustable band sawing machine which comprises a frame (15) provided with two bearings (1,1 1 ') to make a pivot connection with the assembly forming the cutting system which is made up of two slides ( 5.5 ') having cylindrical ends; in which slides a flywheel support (4) which is controlled in translation by two hydraulic cylinders (6,6 ') and which supports two flywheels (3,3') one of which is linked to the engine

(1) donnant le mouvement de coupe au ruban (2); voir figl.  (1) giving the cutting movement to the ribbon (2); see figl.

L'orientation du système de coupe est obtenu par un dispositif constitué d'une roue creuse (7) liée a la partie cylindrique de la glissière (5'), une vis sans fin (8), un tambour  The orientation of the cutting system is obtained by a device consisting of a hollow wheel (7) linked to the cylindrical part of the slide (5 '), a worm (8), a drum

gradué (9), un volant (10) pour manoeuvrer, ainsi des éléments de blocage (12,12').  graduated (9), a handwheel (10) for maneuvering, thus locking elements (12,12 ').

La machine est dotée aussi d'une table mobile(13), guidée dans le sens longitudinal et contrôlée en mouvement d'avance par un système (14) constitué d'un moteur électrique et  The machine is also provided with a movable table (13), guided in the longitudinal direction and controlled in advance movement by a system (14) consisting of an electric motor and

d'une boite de vitesse (boite des avances).  of a gearbox (box of advances).

La pièce (20) à usiner, voir fig2, est soit montée directement sur la table soit sur un  The workpiece (20) to be machined, see fig2, is either mounted directly on the table or on a

porte pièce ayant la possibilité d'être orienté et fixé sur la table.  room holder with the possibility of being oriented and fixed on the table.

La machine de sciage réglable à ruban est une invention qui entre dans le domaine des machines outils conventionnelles ou des machines-outils à commandes numériques dans le cas  The adjustable band sawing machine is an invention which enters the field of conventional machine tools or numerically controlled machine tools in the case

o les systèmes de contrôle (avance de coupe et orientation) seront commandés par ordinateur.  o the control systems (cutting advance and orientation) will be controlled by computer.

Les interêts apportes par la machine de sciage réglable à ruban c'est que cette machine est destinée à faire des opérations d'ébauche pour les travaux de fraisage, dans le but de: - Réduire le temps d'usinage pour des pièces mécaniques ayant des surfaces planes obtenues sur machine appelée fraiseuse soit par la face de la fraise soit par sona profil ou encore par les deux (face et profil), ce qui prouve la réduction du temps d'utilisation d'une machine  The advantages brought by the adjustable band sawing machine is that this machine is intended to make roughing operations for milling work, with the aim of: - Reducing the machining time for mechanical parts having flat surfaces obtained on a machine called milling machine either by the face of the cutter or by its profile or by both (face and profile), which proves the reduction in the time of use of a machine

onéreuse (fraiseuse).expensive (milling machine).

- Récupérer des chutes (21) (voir fig,2), après sciage, qui peut faire le brut pour d'autre  - Recover scrap (21) (see fig, 2), after sawing, which can make the rough for other

pièces au lieu de prendre des soucies pour les coupeaux obtenus sur le poste de fraisage.  parts instead of having to worry about the cutters obtained on the milling station.

- Utiliser l'outil ruban qui coûte moins cher que l'outil fraise.  - Use the ribbon tool which costs less than the cutter tool.
