Abstract
Procedimiento de fabricación de pieza tubular metálica (10, 100, 210) de forma cilíndrica que consiste en someter una preforma tubular (20, 120) cilíndrica de revolución a unas operaciones de deformación plástica, estando dicho procedimiento de fabricación caracterizado porque: - en una primera etapa, se inserta en la preforma (20, 120) un mandril (30, 130, 230) de forma general cilíndrica de revolución que presenta poco juego radial con respecto al diámetro interior de la preforma, incluyendo dicho mandril, solamente en una fracción de su longitud, una o varias ranuras (32, 132, 233) cuyo eje tiene una orientación dada con respecto al eje del mandril, - en una segunda etapa, se hace pasar axialmente el dispositivo preforma-mandril por lo menos por una hilera (40, 140, 141, 142) de sección circular de manera que el metal de dicha preforma fluya anularmente entre la sección de paso de la hilera y el mandril, rellenando las ranuras (32, 132, 233) de dicho mandril e imprimiéndose en ellas en relieve (52, 152, 213), siendo dicho mandril (30, 130, 230) mantenido inmóvil con respecto al extremo anterior de la preforma (20, 120) donde se inicia la deformación, - en una tercera etapa, se extrae axialmente el mandril (30, 130, 230) de la preforma deformada (50, 165, 260) de manera que las partes sin ranuras (31, 131, 231) del mandril axialmente adyacentes a las partes con ranuras suban por las zonas (52, 152, 213) de la preforma deformada impresas en relieve durante la segunda etapa realizando un hinchamiento (62, 215) de la superficie exterior de dicha preforma deformada en el área de dichas zonas impresas en relieve.
