Title: Structure amelioree de grain de poussee
Inventor: ROBBINS PAUL H
IPC: B21C26/00
Filed: 1997-07-18
Abstract: Cette invention concerne une structure de grain de poussée (152) qui permet d'extruder un métal extrudable et qui comprend les éléments suivants: une base (156) de grain de poussée; un connecteur (206) reliant cette base (156) à la tige d'une extrudeuse; un anneau d'usure remplaçable (154) connecté à la partie circonférentielle avant de la base du grain de poussée; un dispositif (158) permettant de fixer l'anneau d'usure (154) amovible à la base du grain de poussée; et enfin, un dispositif (150) assurant l'expansion de l'anneau de manière à ce qu'il entre en contact avec la paroi interne du conteneur de billette d'une presse d'extrusion lors de l'extrusion de ladite billette de métal par cette presse. L'amélioration dans cette invention tient au fait que l'anneau d'usure consiste en un collet métallique possédant une surface interne conique (212) qui converge vers la base du grain de poussée. Le dispositif (150) assurant l'expansion de l'anneau comprend un piston métallique qui possède une tête dont la surface conique va entrer en contact avec la surface conique du collet (154), ceci de manière à assurer l'expansion de ce dernier lorsque ladite tête y pénètre en force lors de l'extrusion. Les surfaces convergentes du collet et de la tête du piston s'étendent sur une distance suffisante pour assurer le télescopage de ladite tête du piston à l'intérieur du collet jusqu'à ce que ce dernier se déploie et entre en contact avec la paroi interne du conteneur de billette.
