Mechanized procedure for splicing parts in water pipes or similar, by means of electrically operated cylinders by solenoid valves, consisting of: # - A first cylinder (1), by means of a jaw (2), holds the tube (3) stopping its advance. # - They act two jaws (4, 5), in bowlers (6, 7) lateral to a central support (8). Two blades (9, 10), in a head (11) in central cylinder (12), cut the tube (3) on said support (8). # - Side cylinders (13, 14), attached to the jaws (4 , 5) lateral, they move separating the segments (3b, 3c) of tube. # - The metal part (15) is placed on the support (8). # - The lateral cylinders (13, 14) move in the opposite direction , approaching the segments (3b, 3c) whose ends are inserted, in the piece (15), fixing it by means of? gills?. # - The two lateral jaws (4, 5) and the extreme jaw (2) are opened.Procedimiento mecanizado para empalme de piezas en conducciones de agua o similar, mediante bombines actuados eléctricamente por electroválvulas, consistiendo en:#- Un prime bombín (1), mediante mordaza (2), sujeta el tubo (3) deteniendo su avance.#- Actúan dos mordazas (4, 5), en bombines (6, 7) laterales a un soporte (8) central. Dos cuchillas (9, 10), en un cabezal (11) en bombín (12) central, cortan el tubo (3) sobre dicho soporte (8).#- Bombines laterales (13, 14), unidos a las mordazas (4, 5) laterales, se desplazan separando los segmentos (3b, 3c) de tubo.#- Se coloca la pieza metálica (15) sobre el soporte (8).#- Los bombines laterales (13, 14) se desplazan en sentido contrario, aproximando los segmentos (3b, 3c) cuyos extremos se insertan, en la pieza (15), fijándose a ella mediante ?agallas?.#- Se abren las dos mordazas (4, 5) laterales y la mordaza (2) extrema.
