Abrégé
(EN)
An improved punch retainer (20) disclosed in which a backing plate (24) extends over a relatively large surface area to dissipate force from a punch (64). A punch retainer body (22) and the backing plate are permanently connected to each other and include passages (38, 40, 42, 44, and 46) which are finally ground after the two have been permanently connected. With this arrangement, it is ensured that passages within the backing plate and retainer body are all properly aligned during formation of the punch retainer. Since the backing plate dissipates force over a relatively large surface area, the punch retainer may be used in heavier applications than prior art punch retainers. A spring passage (56) is closed off by a seal (79) received in the backing plate, allowing the use of standard springs (82).
(FR)
Dispositif de retenue de poinçon (20) amélioré dans lequel une plaque d'appui (24) s'étend sur une surface relativement grande pour dissiper la force émanant d'un poinçon (64). Un corps de retenue (22) et la plaque d'appui sont reliés l'un à l'autre de façon permanente et comportent des passages (38, 40, 42, 44 et 46) qui sont finalement meulés après avoir été fixés à demeure. Ce dispositif permet d'avoir des passages dans la plaque d'appui et dans le corps de retenue bien alignés durant la constitution du dispositif de retenue de poinçon. Comme la plaque d'appui dissipe la force sur une surface relativement grande, le dispositif de retenue de poinçon peut être utilisé dans des conditions plus sévères que les dispositifs de retenue de poinçon de l'art antérieur. Un passage de ressort (56) est fermé par un élément étanche (79) inséré dans la plaque d'appui, ce qui permet l'utilisation de ressorts standard (82).
