INSTALLATION FOR PRESSURE WELDING OF PARTS HEATED BY AN ARC MOVING IN A MAGNETIC FIELD

The installation comprises two clamping devices (2, 3) the first of which is mounted on a frame (1) in a rigid manner and the second one on rods (7) secured by their ends to upsetting hydraulic cylinders (6) with the possibility of reciprocal movements. Each device (2, 3) has a base (5) and a cap (8...

Zusammenfassung:	The installation comprises two clamping devices (2, 3) the first of which is mounted on a frame (1) in a rigid manner and the second one on rods (7) secured by their ends to upsetting hydraulic cylinders (6) with the possibility of reciprocal movements. Each device (2, 3) has a base (5) and a cap (8) hingedly connected to it and moved by means of a hydraulic cylinder, the casing (25) of which is hingedly connected to the base (5), whereas the rod (26) is connected to the cap (8) with which interacts a pressure roller (14) when the parts (4) are clamped. The installation is provided with a lock (15) consisting of an L-shaped lever and with an arrangement (35) for correcting the coaxiality of the parts to be welded, as well as with an arrangement (19) for setting the working gap, consisting of a plunger (20) and a coaxially-mounted adjustable stop (21). L'installation comporte deux dispositifs de serrage (2, 3) dont le premier est solidarisé sur un bâti (1) et le second sur des tiges (7) fixées par leurs extrémités à des vérins hydrauliques de refoulement (6), avec la possibilité de mouvements alternatifs. Chaque dispositif (2, 3) possède une base (5) et un capot (8) qui lui est relié de manière articulée et qui est mû au moyen d'un vérin hydraulique, dont la structure (25) est reliée de manière articulée à la base (5), tandis que la tige (26) est reliée au capot (8) avec lequel coopère un galet de pression (14) lorsque les pièces (4) sont serrées. L'installation comporte un dispositif de blocage (15) constitué d'un levier en forme de L et un agencement (35) pour corriger la coaxialité des pièces à souder, ainsi qu'un agencement (19) pour régler l'écartement de travail, constitué d'un piston (20) et d'une butée réglable (21) montés coaxialement.
