Figure 1 is a sectional view through a plane under axial cal tool, shown in perspective according to one invention.

L'outil, selon l'invention cqmprend un corp (15) qui est pourvu à une extrémité d'un palier (16) dans lequel est guidé l'axe d'une machine tournante. L'axe de celle-ci est logé dans le pignon (19 bis) et coopère avec la dentition (19) de la douille (21). The tool according to the invention cqmprend a body (15) which is provided at one end with a bearing (16) in which is guided the axis of a rotating machine. The axis of the latter is housed in the pinion (19 bis) and cooperates with the teeth (19) of the sleeve (21).

La douille (21) est traversée par une tige (23) pourvue d'un filetage à pas rapide (31), à son extrémité située du côté du fond de la douille (21), pourvue d'un ressort (40) tandis que son autre extrémité supporte des mors (24) pour le sérrage de la queue (8) du rivet. The sleeve (21) is traversed by a rod (23) provided with a quick pitch thread (31), at its end situated on the side of the bottom of the sleeve (21), provided with a spring (40) while its other end supports jaws (24) for tightening the tail (8) of the rivet.

La douille (21) comporte un trou latéral (22) dans lequel est logée la. bille (34) qui coopére avec des rampes (36) prévues sous la forme d'un alésage excentré sur la face corespondante du manchon extérieur (26). The socket (21) has a lateral hole (22) in which the. ball (34) which cooperates with ramps (36) provided in the form of an eccentric bore on the corresponding face of the outer sleeve (26).

le manchon..(26) est relié par exemple vissé au corp (15 bis), coaxial du corps (15) et peut être entraîner en rotation. the sleeve .. (26) is connected for example screwed to the body (15 bis), coaxial with the body (15) and can be rotated.

le manchon (26) est en appui tournant sur la bague (28) avec laquelle il constitue une liaison mobile entre les corps (15) et (15 bis). the sleeve (26) is in rotary support on the ring (28) with which it constitutes a movable connection between the bodies (15) and (15 bis).

Le corps (15 bis) à son extrémité est pourvu d'un logement de forme héxagonale destiné à reçevoir la tête (2) du rivet. The body (15 bis) at its end is provided with a hexagonal housing intended to receive the head (2) of the rivet.

le cylindre (67) qui est vissé sur le corps (15 bi) retient par so extrémité cônique le patin (68) contre 1' action d'un ressort (57). the cylinder (67) which is screwed onto the body (15 bi) retains the conical end of the pad (68) against the action of a spring (57).

Le patin (68) est prolongé en partie arrière par de languettes intérieures constituant des arrêts cscamotables (68 bis). The shoe (68) is extended at the rear by internal tongues constituting cscamotable stops (68 bis).

Lorsque le pignon (19 bis) est entartré en rotation, il entrain la douille (21) et par l'intermédiaire -c0 < la bille (34), la tige (23), le manchon (2t),. le corps (15 bis) se trouve également entraîné en rotation, du fait que les mors (24) et le patin (68) sont coincés dans le conduft héxagonal (25 bis) du corps (15 bis), ladite tige (23) entraine ainsi la tête du rivet (2) qui est bloqué dans le logement (50 ter) du patin (68).  When the pinion (19 bis) is scaled in rotation, it drives the sleeve (21) and via -c0 <the ball (34), the rod (23), the sleeve (2t) ,. the body (15 bis) is also driven in rotation, owing to the fact that the jaws (24) and the shoe (68) are wedged in the hexagonal conduft (25 bis) of the body (15 bis), said rod (23) drives thus the head of the rivet (2) which is blocked in the housing (50 ter) of the pad (68).

La pointe du cône (109 du river(2) est appliquée sur la tôle à percer et ses aretes coupantes (11) pratiquent cm trou dans oelle-oi
Lorsque le trou est pratiqueé, le patin (68) vient porter contre la tôle de sorte que le cerps (15 bis) est frei- né.L'appui du patin (68) engendre un coulissement de la tige (23) qui enolenche la bille (34) dans le pas de vis (31) et entrains la tige (23) contre la force du ressort (40) provocant le tirage des mors (24) sur la queue (8) de la t gei du rivet, ce qui provoque un épanouissenent da corps (1) du rivet
Lorsque la traction exercée sur la queue (8) dépasse un seuil déterminé celle-cf se brise au droit. de la gorge
(12) et est evacué par le tube (21 bis) situé dans l@ouver- ture (33) du corps (15). Dès qu'on écarte le. patin de la. tôle l'ensemble revient dans la posftion initiale par l'action des.The tip of the cone (109 of the river (2) is applied to the sheet metal to be drilled and its cutting edges (11) make a cm hole in oelle-oi
When the hole is made, the shoe (68) comes to bear against the sheet so that the hook (15 bis) is braked. The support of the shoe (68) generates a sliding of the rod (23) which enolenche the ball (34) in the thread (31) and draws the rod (23) against the force of the spring (40) causing the pulling of the jaws (24) on the tail (8) of the t gei of the rivet, which causes the body (1) to open out of the rivet
When the traction exerted on the tail (8) exceeds a determined threshold, it breaks right. throat
(12) and is discharged through the tube (21 bis) located in the opening (33) of the body (15). As soon as we dismiss the. skate of the. sheet metal the whole returns to the initial posftion by the action of.

ressorts (40) et (57).springs (40) and (57).

Bien entendu, l'invention n'est pas limitêe an mode de rdalisation qui vient autre déorit et représente, on pour- ra y apporter de nombreuses modifications de détail sans sor- tir pour cela du cadre de l'invention.  Of course, the invention is not limited to an embodiment which comes in another form and represents, it is possible to make numerous modifications of detail there without departing from the scope of the invention.
