Abstract

Pour le démoulage des bagues 24, 25, 26, le dispositif 4 fonctionne comme suit : par sa face terminale avant, le dispositif est poussé contre la première bague 24 et de l'air comprimé est insufflé en même temps vers la bague 24, à travers la chambre annulaire 32 entre la douille exterieure 6 et la douille intérieure 7, par des perçages répartis à la périphérie. Dans la gorge annulaire 33 servant de logement à la bague 24, il se forme ainsi un coussin d'air comprimé, sous l'action duquel, lorsque le dispositif 4 est poussé sur la bague 24, celle-ci est éloignée de sa gorge 33 et appliquée contre la bague suivante 25, qui est ensuite extraite selon un processus analogue.For demolding the rings 24, 25, 26, the device 4 operates as follows: by its front end face, the device is pushed against the first ring 24 and compressed air is blown at the same time towards the ring 24, to through the annular chamber 32 between the outer sleeve 6 and the inner sleeve 7, through holes distributed around the periphery. In the annular groove 33 serving as a housing for the ring 24, a compressed air cushion is thus formed, under the action of which, when the device 4 is pushed on the ring 24, the latter is moved away from its groove 33 and applied against the next ring 25, which is then extracted according to a similar process.
