An assembly (10, 50) for retaining a work piece and fitting together for placement in a swage machine. The assembly (10, 50), includes a die (16, 54) and a collar (18, 56) to keep the work piece from moving during the swaging process. The collar (18, 56) includes two clamping sections (28, 30 and 70, 72) that are connected together, such as by a hinge (32, 74). The collar (18, 56) is placed about the work piece and then clamped in place by a retaining bolt (34, 76) at the opposing end of the clamping section (28, 30 and 709, 72). The die (16, 54) includes a recess (22, 60) for holding the collar and a recess (24, 62) for the tube. The assembly (10, 50) includes an anti-rotation feature to minimize rotation feature to minimize rotation of the collar (18, 56) within the recess (22, 60). One example of an anti-rotation feature is the formation of the recess (22, 60) and the collar (18, 56) in corresponding hexagonal shapes. The die (16, 54) may also include a recess (20, 58) for retaining a fitting to be swaged to the work piece. The die and collar assembly (10, 50) eliminates the need for nylon inserts and eliminates work piece rotation and axial movement during the automated swaging process.

La présente invention concerne un ensemble (10, 50) destiné à retenir une pièce et un raccord ensemble en vue d'un placement dans une machine à sertir. Cet ensemble (10, 50) comprend une matrice (16, 54) et une bride (18, 56) destinés à empêcher la pièce de se déplacer pendant le processus de sertissage. La bride (18, 56) comprend deux parties raccord (28, 30 et 70, 72) qui sont connectées entre elles, par exemple par une articulation (32, 74). Cette bride (18, 56) est placé autour de la pièce, puis fixé en place par un boulon de retenue (34, 76) au niveau de l'extrémité opposée de la partie raccord (28, 30 et 70, 72). La matrice (16, 54) comprend un évidement (22, 60) destiné à tenir la bride et un évidement (24, 62 ) pour le tube. Cet ensemble (10, 50) comprend une caractéristique anti-rotation destinée à minimiser la rotation de la bride (18, 56) dans l'évidement (22, 60). La formation de l'évidement (22, 60) et de la bride (18, 56) en formes hexagonales correspondantes est un exemple de caractéristique anti-rotation. La matrice (16, 54) peut aussi comprendre un évidement (20, 58) destiné à retenir un raccord à sertir sur la pièce. Cet ensemble (10, 50) matrice et bride permet de supprimer les inserts de nylon et d'éliminer la rotation et le déplacement axial de la pièce pendant le processus de sertissage automatisé.
