Abstract
Mandrin de formage à segments rétractables. Le mandrin de formage selon la présente invention comporte une première et une deuxième série de segments rétractables 11, respectivement 20, et des moyens pour actionner lesdits segments rétractables, ces moyens comprenant un premier, respectivement un deuxième manchon 9 respectivement 27, coulissant axialement sur un arbre central 25, et sur lequel est articulé chaque segment de la première, respectivement de la seconde série de segments au moyen de deux biellettes parallèles 12, respectivement 36, axialement décalées, et des surfaces d'appui 22, respectivement 23 orthogonales à l'axe du mandrin prévues pour maintenir axialement les segments en cours de leur déplacement radial. Application à la réalisation de gorges annulaires de section non circulaire à l'intérieur des portions d'emboîtement de tubes en matière thermo-plastique.
