Abstract

L'invention concerne un extracteur (1) pour un système d'extrusion (4). Le système d'extrusion comprenant un arbre cannelé (40) et des éléments de vis (41) montés successivement sur l'arbre cannelé pour former une vis d'extrusion (42). L'extracteur (1) comprend un premier dispositif de maintien (3) configuré pour immobiliser l'arbre cannelé (40), un second dispositif de maintien (5) configuré pour agripper un des éléments de vis (41) et un dispositif d'actionnement (6) configuré pour déplacer le second dispositif de maintien (5) selon un axe de translation (X1) parallèle à un axe longitudinal (X3) de l'arbre cannelé (40) en sorte d'écarter ledit élément de vis (41) agrippé du reste de la vis d'extrusion (42). L'extracteur permet de dégripper les éléments de vis de l'arbre cannelé.The invention relates to an extractor (1) for an extrusion system (4). The extrusion system comprising a splined shaft (40) and screw elements (41) successively mounted on the splined shaft to form an extrusion screw (42). The extractor (1) comprises a first holder (3) configured to immobilize the splined shaft (40), a second holder (5) configured to grip one of the screw elements (41) and a device for actuation (6) configured to move the second holding device (5) along a translation axis (X1) parallel to a longitudinal axis (X3) of the splined shaft (40) so as to move said screw element (41) apart ) gripped by the rest of the extrusion screw (42). The extractor allows the screw elements to be released from the splined shaft.
