DEVICE FOR AUTOMATIC TWO-SIDE WELDING OF RIBS BY INTERMITTENT WELD Russian patent published in 1997 - IPC

FIELD: mechanical engineering; automatic two-side welding of ribs to plates with corrugations and other obstacles on electrode movement path. SUBSTANCE: tracer of device is hinge secured on carriage for rocking relative to axis parallel to axis of lead screw. Tracer has reciprocating motion mechanism, two spring-loaded mirror like supports, deflecting rollers, lead screw drive and flanges. Flanges are connected with each other by means of rods on which brackets are mounted for movement. Brackets are mechanically coupled with lead screw. Welding torches are secured on brackets. Spring- loaded supports are rigidly coupled with rods and are made in form of bell- cranks with copying rollers mounted on some ends in plane square to axis of lead screw. Deflecting rollers are mounted on other ends for engagement with cams installed of carriage. EFFECT: enlarged operating capabilities. 4 dwg
