Beschreibung
Zusammenfassung:	The invention discloses a heat exchanger tube bundle assembly elbow welding device, and relates to the field of heat exchanger elbow welding devices, the heat exchanger tube bundle assembly elbow welding device comprises a fixing plate, the two ends of the bottom surface of the fixing plate are rotatably connected with a straight tube frame and an elbow frame respectively, and the two sides of the straight tube frame and the two sides of the elbow frame are slidably connected with supports; telescopic gears in threaded connection with the support are rotationally connected to the interiors of the support and the pipe bending frame, and synchronous gears meshed with the telescopic gears are rotationally connected to the top faces of the two sides of the straight pipe frame and the top faces of the two sides of the pipe bending frame. The straight pipe frame and the bent pipe frame which are matched with each other are rotationally connected to the mounting plate, the supports are slidably connected to the two
