Description

Il est connu de fabriquer des coudes de raccordement en refoulant un tronçon de tube rectiligne dans une matrice de forme correspondante tout en chassant simultanément une série de billes à l'intérieur du tube. It is known to make connection elbows displacing a straight pipe section in a corresponding matrix form while removing simultaneously a series of balls inside the tube. Ce procédé est mis en oeuvre à l'aide d'une machine comprenant un piston extérieur de refoulement qui est monté coulissant dans la matrice, un piston intérieur qui peut coulisser dans le piston extérieur et est propre à chasser les billes dans le tronçon de tube, et des moyens pour faire coulisser les deux pistons. This method is implemented using a machine comprising an outer piston displacement which is slidably mounted in the die, an internal piston which is slidable in the outer piston and is adapted to drive the ball in the tube section and means to slide the two pistons.

La présente invention a pour objet une machine de ce type qui présente l'avantage de donner de bien meilleurs résultats que lorsque les moyens pour déplacer les pistons sont, comme actuellement, constitués par des poussoirs hydrauliques. The present invention relates to a machine of this type has the advantage of giving better results than when the means for moving the pistons are, as at present, consist of hydraulic tappets.

La machine selon l'invention est caractérisée en ce qu'elle comporte un plateau qui est monté pivotant autour d'une came fixe et comporte un certain nombre de postes de travail, et en ce que cette came présente deux rampes périphériques propres à déplacer respectivement le piston intérieur et le piston extérieur de chaque poste de travail. The machine according to the invention is characterized in that it comprises a plate which is pivotally mounted about a fixed cam and comprises a number of workstations, and in that said cam comprises two ramps own device moving respectively the inner piston and the outer piston of each workstation.

On a décrit ci-après à titre d'exemple non limitatif, un mode de réalisation de la machine selon l'invention avec référence aux dessins annexés dans lesquels There is described hereinafter by way of non-limiting example, one embodiment of the machine according to the invention with reference to the accompanying drawings in which
Les Figures 1 à 4 sont des vues en coupe de Figures 1 to 4 are sectional views of
l'un des postes de travail, à des stades de one of the workstations, at stages of
fonctionnements différents;- different functions -
La Figure 5 est une vue en plan de la came Figure 5 is a cam plan view
fixe. fixed.

La machine de fabrication de coudes de raccordement selon l'invention comprend une came fixe 1 qui est de révo1ution#flt#urd'un axe 2, et présente deux rampes 3 et 4. Un plateau tournant 5 est monté pivotant autour de l'axe 2 et comporte un certain nombre de postes de travail, par exemple dix. The connecting elbows making machine according to the invention comprises a fixed cam which is one of révo1ution flt # # urd'un axis 2 and has two ramps 3 and 4. A turntable 5 is mounted pivotally about the axis 2 and comprises a number of workstations, for example ten.

Chaque poste de travail comporte une matrice 6 dans laquelle est formée une empreinte coudée de façonnage 7. Each workstation comprises a matrix 6 which is formed in an angled shaping footprint 7.

L'une des extrémités de cette empreinte se trouve en regard d'un distributeur 8 pour des billes 9 dont le diamètre est sensiblement égal au diamètre intérieur du tube avec lequel le coude doit être réalisé. One end of this imprint located opposite a distributor 8 for the balls 9 whose diameter is substantially equal to the inner diameter of the tube with which the elbow to be achieved. Un verrou pneumatique 10 est prévu à la base de ce distributeur. An air lock 10 is provided at the base of the dispenser.

L'autre extrémité de l'empreinte 7 se trouve en regard d'un piston extérieur 11 qui est monté coulissant dans le plateau 5 dans la direction de l'axe de l'alésage 7; The other end of the cavity 7 is situated opposite an outer piston 11 which is slidably mounted in the tray 5 in the direction of the axis of the bore 7; un ressort 12 tend à appliquer ce piston contre la rampe 4 avec interposition de billes 13. L'extrémité lia de ce piston 11 peut coulisser dans l'empreinte 7 de la motrice 6 et a un diamètre extérieur égal au diamètre de cette empreinte. a spring 12 tends to press the piston against the ramp 4 with the interposition of balls 13. The end IIa of the piston 11 can slide in the cavity 7 of the motor 6 and has an outer diameter equal to the diameter of the footprint.

Dans le piston 11 est monté coulissant un deuxième piston 14; In the piston 11 is slidably mounted a second piston 14; un ressort 15 tend à appliquer ce piston contre la rampe 3 avec interposition d'une bille 16. a spring 15 tends to press the piston against the ramp 3 with the interposition of a ball 16.

Le trajet nécessaire au plateau 5 pour former un coude de raccordement est égal à un tour du plateau autour de la came 1. The route necessary to plate 5 to form a connection bend is equal to one turn of the plate around the cam 1.

A la Figure 1, un tronçon de tube 17,dont le diamètre extérieur est égal à celuide l'alésage 7, a été introduit dans ltempreints 7 et le piston ll a été amené à proximité du débouché de cette empreinte. In Figure 1, a tube section 17, whose outer diameter is equal to celuide the bore 7, was introduced into ltempreints 7 and ll piston has been brought close to the mouth of this imprint. Les extrémités de ce tronçon ont été ajustées en fonction de l'angle du coude qui peut par exemple être de So e, 600 ou de 750; The ends of this section were adjusted according to the angle of the bend which may for example be of So e, 600 or 750; dans le cas d'un coude à 900, les extrémités du tronçon ont été coupées 450. in the case of an elbow 900, the ends of the section 450 have been cut.

Le plateau tournant actionne un micro-interrupteur qui actionne le vérou 10: les billes 9 tombent dans la matrice 6 et s'introduisent dans le tube 17, puis dans le piston li jusqu'≈ce qu'elles soient au contact du piston 14 (Figure 2). The turntable actuates a microswitch 10 which actuates the Verou: the balls 9 falling into the die 6 and are introduced into the tube 17 and then into the piston li jusqu'≈ce that they contact the piston 14 ( Figure 2).

Le plateau continuantde tourner, le piston extérieur ll coulisse dans la matrice 6, sous l'effet de la rampe 4 et le piston intérieur 14 coulisse dans le piston 11, sous l'effet de la rampe 3, mais légèrement plus vite que le piston 11. Le piston 14 pousse les billes 9 dans le tube 17; The tray continuantde turn, the outer lt piston slides in the die 6, under the effect of the ramp 4 and the inner piston 14 slides in the piston 11, under the effect of the ramp 3 but slightly faster than the piston 11. the piston 14 pushes the balls 9 in the tube 17; le piston ll refoule à l'intérieur de l'empreinte 7 le tube 17 qui est guidé intérieurement par les billes. ll piston displaces inside the cavity 7 the tube 17 which is internally guided by the balls. Le tube prend une forme coudée (Figure 3). The tube assumes a bent shape (Figure 3).

Puis le piston 14 continue d'avancer; Then the piston 14 continues to advance; les billes 9 sortent du coude en le calibrant et sont verrouillées dans le chargeur 8 par le verrou 10 (Figure 4). the balls 9 out of the elbow in the calibrant and are locked in the magazine 8 by the bolt 10 (Figure 4).

En fin de cycle les pistons il et 14 reculent, le coude est éjecté et un nouveau cycle peut avoir lieu. When the cycle pistons it and 14 were down, the elbow is ejected and a new cycle can take place.

il va de soi que la présente invention ne peut être considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre au contraire toutes les variantes. it goes without saying that the present invention can not be considered limited to the embodiment described and shown, but on the contrary covers all variants.
